The Benefits of Regular Under-the-Hood Car Inspections

September 7, 2024 by Denver Express Car Care

The average new car price sits at $47,244. Whether you’re paying in cash or taking out a several year loan, it’s a lot of money to put into your vehicle. Caring for it is part of ownership. 

For many, under-the-hood inspections are an important part of preventative maintenance for your car. But it’s not something you can have done anywhere. Taking it to an in-and-out specialty service will give it a basic check at best. They look for what they service. They sell you on what makes them money. 

That means your under-the-hood inspection is anything but complete. 

The Role of Under-The-Hood Inspections On Car Longevity

Have you ever seen someone sitting on the side of the road, hood open, smoke billowing out, and they’re pacing with their phone to their ear? What went wrong? Could the situation have been avoided? Can you do things differently?

In short, they ignored early warning signs. They didn’t pay attention to what was going on under the hood. And it led them to be stranded by the side of the road. 

Vehicle maintenance isn’t a difficult process. With regular under-the-hood inspections, you’ll experience a number of key benefits, including:

The Benefits of Regular Under-the-Hood Car Inspections
  • Early Detection of Problems: A trained mechanic can easily pick up on potential hazards before they become significant problems. Identifying issues such as leaks, worn-out belts, or low fluid levels early on helps prevent breakdowns and keeps your car running smoothly.
  • Improved Engine Performance: Keeping the engine and its components in good condition ensures optimal performance, leading to better fuel efficiency and lower emissions.
  • Enhanced Safety: Regular checks reduce the risk of mechanical failures that could compromise your safety on the road. No more worrying whether you’ll be the one on the side of the road. 
  • Cost Savings: Preventive maintenance helps avoid expensive repairs by addressing minor issues before they become major problems. Catch them early before they escalate. 
  • Prolonged Vehicle Lifespan: By maintaining all under-the-hood components, you ensure your car remains reliable for many years, maximizing your investment. You won’t have to think about a new car for many years to come. 

What Do Mechanics Look For Under The Hood?

An under-the-hood inspection usually involves one of our mechanics carefully examining the engine bay and its components. This can be done visually and by using diagnostic tools. The inspection often takes place during routine maintenance (like an oil change) or as part of a more comprehensive service check. Going on a road trip? This is a perfect time for a more comprehensive service check. 

We look for many things. 

Engine Oil Level and Quality

Out mechanics check the oil level using the dipstick and assess the oil’s color and consistency. Dirty or low oil can indicate engine wear or leaks and may require an oil change or further investigation.

Coolant Level and Condition

The coolant level is checked in the reservoir, and the condition of the coolant is evaluated. Our mechanics look for signs of contamination or leaks, which can lead to engine overheating and damage.

Belts and Hoses

Our mechanics inspect the condition of drive belts (such as serpentine or timing belts) for cracks, fraying, or signs of wear. Hoses are checked for leaks, cracks, or bulging, which can indicate a potential failure.

Battery Health

The battery is checked for corrosion on terminals, secure mounting, and adequate charge levels. Our mechanics may use a multimeter to test the battery’s voltage and overall health, looking for signs of aging or potential failure.

Air Filters

The engine air filter is inspected for dirt and debris, which can reduce engine performance and fuel efficiency. The cabin air filter may also be checked to ensure it is clean and functional.

Fluid Levels

Various fluid levels, such as brake fluid, transmission fluid, power steering fluid, and windshield washer fluid, are checked to ensure they are at the proper levels and in good condition. Our mechanics look for signs of contamination or leakage.

Spark Plugs and Ignition Components

Spark plugs and ignition wires are inspected for wear, corrosion, or damage. Worn spark plugs can cause engine misfires, reduced performance, and increased fuel consumption.

Fuel System Components

Our mechanics check for any visible leaks in the fuel lines and inspect the fuel injectors for proper operation. They may also look at the fuel filter to ensure it isn’t clogged.

Radiator and Cooling System

The radiator and cooling system components, including the radiator cap, water pump, and thermostat, are inspected for leaks, corrosion, and proper function. Our mechanics also check for proper airflow and cooling fan operation.

Exhaust System

The exhaust manifold and related components are inspected for cracks, leaks, or loose fittings, which can affect engine performance and emissions.

Wiring and Electrical Connections

Our mechanics look for any damaged or corroded wires, loose connections, or signs of electrical shorts, which can lead to various electrical issues and failures.

Brake Components (if visible)

While most brake components are located under the car, some parts like the brake master cylinder and fluid reservoir are under the hood. Our mechanics check for leaks, proper fluid levels, and signs of wear or damage.

Visual Inspection for Leaks and Damages

A general visual inspection for any fluid leaks, unusual noises, or visible damage is conducted. Our mechanics look for anything out of the ordinary that could indicate a problem.

Under-The-Hood Car Inspection Is What You Need Right Now

How to Maintain Your Car’s Fuel Economy as It Ages

September 3, 2024 by Denver Express Car Care

New cars are wonderful. You slide behind the wheel, start the engine, and see everything come to life. The engine purrs. You feel it as you let your hand glide over the dashboard. There’s nothing quite like a new car. 

But then, life happens. You drive. You go to work. Take a vacation. And little by little, your new car starts to break in, wear down. 

You start changing fluids. You start replacing parts. Will your car ever work the same as it did when you first drove it off the lot? 

Will you ever experience the same fuel economy as your car ages? 

What Is Fuel Economy?

Fuel economy is something we all pay attention to when we’re looking at cars. The more you drive, the more fuel economy becomes. You know you’ll be spending more at the pump with a car that gets 10mpg over a car that gets 40mpg. 

But what goes into calculating fuel economy? It can be influenced by four things. 

It starts with your vehicle-specific attributes. This includes things like your car’s engine size and type, the vehicle weight, what kind of tires are on your car, and how much pressure they have. Are you driving an automatic or a manual? What type of fuel does your car use? It also depends on the overall design and how aerodynamic the body type. 

How to Maintain Your Car’s Fuel Economy as It Ages

It also depends on your driving habits. Frequent and rapid acceleration or hard braking reduces fuel economy. Smooth and gradual changes in speed help conserve fuel. How far do you travel from home each day? How fast or slow is your drive? If you tow or carry a heavy load, your fuel economy will be reduced. 

Where does your drive take you? Driving on hilly or mountainous terrain requires more energy (fuel) to climb inclines and affects fuel economy. Cold weather can reduce fuel efficiency because engines take longer to reach optimal operating temperatures, and air conditioning or heating systems consume additional power. Wind resistance also increases in adverse weather conditions. And then those weary days where it’s nothing but traffic – stop-and-go traffic decreases fuel economy due to frequent acceleration and deceleration.

You do have control over the fourth category – maintenance and condition of your car. A well-maintained engine runs more efficiently. Regular oil changes, clean air filters, and proper spark plug conditions can improve fuel economy. Proper alignment and balanced tires reduce rolling resistance and improve fuel efficiency. A properly functioning exhaust and emission control system ensures optimal engine performance and fuel efficiency.

What Causes Fuel Efficiency To Change Over Time? 

In short, the answer is: Yes. As an engine ages, fuel economy can decrease somewhat. But this decrease has less to do with the age of the engine and more to do with the condition of the engine and other engine components. 

Over time, an engine’s components can wear down, reducing its efficiency. Spark plugs and valves may not seal as effectively, leading to decreased compression and fuel efficiency. 

Fuel injectors can become clogged with deposits, leading to inefficient fuel delivery and poor combustion, which reduces fuel economy. Oxygen sensors help manage the air-fuel mixture in the engine. Over time, these sensors can become less accurate, leading to a suboptimal mixture and reduced fuel efficiency. 

A clogged or failing catalytic converter can increase backpressure in the exhaust system, reducing engine efficiency and fuel economy. As a transmission ages, it may not shift as smoothly or efficiently, which can increase fuel consumption, especially in automatic or CVT transmissions.

As the components wear down, fuel efficiency also starts depending on how much maintenance you provide over time. 

A clogged or dirty air filter restricts airflow to the engine, causing it to work harder and consume more fuel. Worn spark plugs can cause incomplete combustion, leading to a reduction in fuel efficiency. 

Tires that are worn, underinflated, or misaligned increase rolling resistance, requiring more energy (fuel) to move the vehicle. Using old or incorrect engine oil, or having low levels of other critical fluids, can increase friction within the engine and reduce efficiency. If brakes are improperly adjusted or components are sticking, it can cause unnecessary drag, which requires more fuel to overcome.

Then, it also depends on things outside of your car and driving experience. The load and weight of your vehicle. Environmental factors such as temperature changes. Worn out and out-of-date technology. 

What’s The Key To Improving Fuel Efficiency? 

Awareness is the key to maximizing your car’s fuel efficiency. The more aware you are that your daily habits control how well your vehicle operates, the more fuel efficient your car will remain over time. It starts with:

Regular maintenance. That means keeping the engine tuned and replacing components like spark plugs, filters, and oxygen sensors. Use the recommended grade of motor oil and change it at the intervals specified by the manufacturer. Check tire pressure regularly and inflate to the manufacturer’s recommended levels. Proper wheel alignment and balance reduce rolling resistance and prevent uneven tire wear.

Optimizing your driving habits. Avoid rapid acceleration and hard braking. Observing speed limits, as fuel efficiency generally decreases at speeds above 50-60 mph. Avoid excessive idling, as modern engines don’t need to idle to warm up and restarting the engine uses less fuel than idling.

Reducing your vehicle load and drag. This includes removing unnecessary items from the trunk or back seat to reduce load. Removing roof racks and carriers that increase aerodynamic drag, especially at higher speeds. Closing windows as you reach higher speeds on the highway, which also increases drag. 

Using efficient routes. You know those quick trips to the store? It’s time to start planning out efficient routes and avoid short trips. Combine them into one longer trip, planning out your route to avoid heavy traffic and numerous stops. It might sound like a lot of planning, but through awareness, you’ll start to notice new things about your trip. You’ll find easy ways to make it more beneficial for you and your car. 

Fuel Economy Starts With Maintenance

How to Diagnose and Repair Car Vibrations

August 28, 2024 by Denver Express Car Care

Driving is often a fun experience. Head out on the open road, roll down the windows, and enjoy the experience. Something about slipping behind the wheel makes you feel like you’re having fun. 

Even as you rush from home to work and back again, the car might be the one place you can truly relax. Turn up your favorite tunes and sing along. For a few moments, it’s just you and the road – why not enjoy your time alone?

Unless your car doesn’t feel right. Suddenly, it takes on an entirely different experience. You feel it vibrating, shuddering, shaking, even wobbling to and fro. 

Maybe it’s a wobble in your steering wheel. It’s an annoyance, but you can live with it. Or maybe you feel it in your seat – it appears to be everywhere. 

Should you live with vibrations? Or is it a sign of something more?

When Does It Happen? When Do You Notice It?

Problems rarely occur overnight. They start small and build. This is where it pays to pay attention to the details. Before you bring your car to the mechanic, take a moment to observe when and where you feel the vibration in your car. Noticing these details can significantly help your mechanic diagnose the problem more efficiently. You can do so by asking yourself a series of questions. 

How to Diagnose and Repair Car Vibrations
  • Do you feel the vibration when you’re accelerating, maintaining a constant speed, or slowing down?
  • Is it more pronounced at certain speeds, like when you hit 60 mph?
  • Does the vibration change when you’re driving on different types of roads?
  • For instance, do you feel it more on smooth highways or bumpy city streets?
  • Identify where you feel the vibration the most. Is it in the steering wheel, seat, or floorboard?
  • Do passengers feel it too, or is it just on your side?
  • Does the vibration occur when the car is idling, or only when you’re driving?
  • Pay attention to whether it’s consistent or comes and goes with certain actions, like turning or braking.
  • Notice if the vibration is worse during certain weather conditions, like after a cold start in the morning or on hot afternoons.

Car Vibrations – Wheel or Seat? 

When you feel a vibration in your car, the location of the vibration can often point to different causes. Generally, vibrations can be classified into two main categories:

Vibration in the Steering Wheel

  • Wheel Imbalance: If you notice the steering wheel shaking at higher speeds, it’s often due to unbalanced wheels. This is one of the most common causes of steering wheel vibrations.
  • Alignment Issues: Misalignment can also lead to a shaky steering wheel, especially if the car pulls to one side.
  • Worn Suspension Components: Issues with tie rods, ball joints, or wheel bearings can cause vibrations that are felt in the steering wheel.

Pay attention to whether the vibration intensifies at certain speeds or when you’re turning. For example, vibrations that worsen during turns could indicate a problem with the front suspension.

Vibration in the Seat or Floorboard

  • Driveline Problems: If you feel the vibration in your seat, especially when accelerating, it could be related to the driveshaft or rear differential in rear-wheel-drive vehicles.
  • Tire Issues: A flat spot on a tire, worn-out tires, or improperly inflated tires can cause vibrations felt through the seat or floorboard.
  • Engine or Transmission Mounts: Worn or damaged mounts can lead to vibrations that are more noticeable in the cabin, especially when idling.

Notice if the vibration occurs more when accelerating, driving at certain speeds, or when the car is loaded with passengers or cargo. Vibrations that change with speed or load could indicate driveline or tire issues.

Getting Into The Details – What Different Kinds of Vibrations Mean

Still confused? We get it. Noticing your car isn’t behaving as it once did is difficult at best. You simply want to get in your car and drive. Feeling a vibration puts you on edge … Now what? 

But that’s where it helps you to start asking the questions we listed above. By finding the root of the problem, it makes it that much easier to talk with your mechanic. It also helps you get in and out of the repair shop quicker. 

So let’s talk about various vibrations and what they might mean. 

You Feel Constant Vibration at High Speeds

One of the most probable causes is unbalanced tires. If you notice a steady vibration that becomes more pronounced as you increase speed, it’s likely due to unbalanced tires. This often occurs when a wheel loses weight or after a tire has been replaced or rotated without proper balancing.

You Notice Vibration When Accelerating

A vibration that intensifies when you press the gas pedal could point to a problem with the driveshaft or CV joints, especially in vehicles with rear-wheel or all-wheel drive. It might also indicate a worn or damaged axle.

There’s a Distinct Vibration When Braking

If your car vibrates when you apply the brakes, especially at higher speeds, it’s usually a sign of warped brake rotors. The uneven surface of the rotor can cause the brake pads to grab inconsistently, leading to a noticeable vibration.

You Notice a Vibration While Idling

Vibrations most noticeable when your car is stationary and the engine is running could indicate worn engine or transmission mounts. These mounts hold the engine and transmission in place, and when they wear out, the vibrations can be felt throughout the car.

You Feel a Vibration When Turning

You start to lean into a curve, and you feel a vibration ripple through your vehicle. If your car vibrates or shudders when turning, it could be due to problems with the suspension or steering components, such as worn-out tie rods or ball joints. It might also suggest an issue with the power steering system.

You Notice Vibrations in Specific Weather Conditions

Some vibrations might be more noticeable in cold weather, especially right after starting the car. This could be due to flat spots on tires that haven’t warmed up or issues with engine components that are more sensitive to temperature changes.

Are You Experiencing Vibrations Inside Your Vehicle? 

If so, it’s time to schedule an appointment with one of our mechanics. 

Vibrations can signal a host of different concerns. While some may be more concerning than others, every vibration should be checked and corrected to ensure your drive continues to stay safe and secure. 

We can help. Schedule your appointment today. We’ll have you back on the road in no time.

The Importance of Regular Headlight and Tail Light Checks

August 24, 2024 by Denver Express Car Care

Sometimes even the smallest problems can have a big impact on your car. 

What if your tail lights aren’t working? (Maybe you’ve been behind a car without working tail lights.) The person behind you doesn’t notice … until it’s too late. Now you’re faced with car repairs, insurance inquiries, and lots of time and money wasted. 

Headlight and tail light checks might not seem that important. Do you really need to minotaur them regularly? The short answer is: Yes. 

At a minimum, headlights and tail lights keep you, your passengers, and the traffic around you safe. They can also alert you to a bigger problem. Is your electrical system running well? 

Understanding Your Vehicle’s Lighting System

Your vehicle’s lighting system is more than just headlights and tail lights—it’s an essential safety feature that helps you see and be seen on the road. The system includes several components, each serving a critical function in different driving conditions.

Headlights are your primary source of illumination when driving at night or in low-visibility conditions. They come in two main types: low beam and high beam. Low beams are angled downwards to prevent blinding oncoming traffic, while high beams provide a broader, more intense light for driving in areas with no street lighting.

The Importance of Regular Headlight and Tail Light Checks

Tail lights, located at the rear of your vehicle, are equally important. They ensure your car is visible to drivers behind you, especially in low light or poor weather conditions. When you press the brake pedal, the brake lights—part of the tail light assembly—illuminate, signaling your intention to slow down or stop.

Connected to your lighting system includes turn signals, which communicate your intention to turn or change lanes, and hazard lights, used to alert other drivers to a potential danger or an emergency situation. Some vehicles also feature daytime running lights (DRLs), which automatically turn on to enhance your visibility during the day.

How Often Should I Check My Vehicle’s Lights?

Regularly checking your vehicle’s lights is a simple yet essential task to ensure your safety and compliance with road regulations. But how often should you inspect them?

  • Monthly Inspections. A good rule of thumb is to check all of your vehicle’s lights—headlights, tail lights, brake lights, turn signals, and hazard lights—at least once a month. This routine helps you catch any issues before they become serious problems. A quick walk-around of your vehicle while the lights are on will allow you to identify any bulbs that are dimming, flickering, or have burned out.
  • Before Long Trips. Before heading out on a long drive, especially at night or during inclement weather, take a few minutes to inspect your lights. Ensuring that all lights are functioning correctly can prevent unexpected failures when you’re far from home.
  • After Replacing a Bulb. If you’ve recently replaced a light bulb, it’s wise to check it periodically for a few weeks to ensure it was installed correctly and is working as expected.
  • During Routine Maintenance. Incorporate light checks into your vehicle’s routine maintenance schedule, such as oil changes or tire rotations. Most service centers will check your lights as part of their standard inspection process, but it’s always a good idea to request it if not offered.
  • Seasonal Changes. As the days grow shorter in the fall and winter, you rely more on your vehicle’s lighting system. This is an ideal time to conduct a thorough check and make any necessary adjustments, such as headlight alignment or cleaning lenses to remove cloudiness.

Can I Upgrade My Standard Headlights To LED?

Upgrading your standard headlights to LED (Light Emitting Diode) bulbs is an increasingly popular choice among drivers looking to enhance their vehicle’s lighting performance. LED headlights offer several benefits, but before making the switch, it’s important to understand both the advantages and considerations involved.

Advantages of LED Headlights

  • Brighter and Clearer Light. LED headlights produce a brighter and more focused beam of light compared to traditional halogen bulbs. This improved illumination enhances visibility, particularly at night and in adverse weather conditions, making your drive safer.
  • Energy Efficiency. LED bulbs consume less power than halogen bulbs, reducing the strain on your vehicle’s electrical system. This efficiency can contribute to a slight improvement in fuel economy over time.
  • Longer Lifespan. LEDs have a significantly longer lifespan compared to halogen bulbs, often lasting up to 20,000 hours or more. This means fewer replacements, saving you money in the long run.
  • Modern Aesthetic. LEDs emit a crisp, white light that can give your vehicle a modern and sleek appearance, enhancing both functionality and style.

Considerations Before Upgrading

  • Compatibility. Not all vehicles are equipped to handle LED bulbs without modifications. Some cars may require additional components, like a heat sink or a CANbus adapter, to ensure the LED bulbs work correctly and avoid issues such as flickering or error codes.
  • Legal Compliance. Check your local regulations before upgrading, as some areas have specific laws regarding headlight modifications. Installing non-compliant LED bulbs could result in fines or your vehicle failing an inspection.
  • Installation. While some LED kits are designed for easy plug-and-play installation, others may require more advanced skills or professional help. Improper installation can lead to poor performance or even damage to your vehicle’s lighting system.
  • Beam Pattern. LED headlights can sometimes produce a different beam pattern compared to halogen bulbs. It’s crucial to ensure the beam is properly aligned to avoid blinding oncoming traffic.

Electrical Problems – When To Seek Help

Your vehicle’s lighting system is a critical safety component on the road, and when it starts to malfunction, it’s essential to address the issue promptly. While some minor lighting issues, like replacing a burnt-out bulb, can be handled on your own, there are certain electrical problems that require professional assistance. Here’s when you should consider seeking help:

Flickering or Dim Light

If your headlights, tail lights, or interior lights are flickering or appear dim, it could be a sign of a more serious electrical issue, such as a failing alternator or a weak battery. These components are vital to your vehicle’s operation, and ignoring the signs could lead to more significant problems or even leave you stranded.

Lights Not Turning On

When your lights fail to turn on, even after replacing the bulbs, it could indicate a wiring issue, a blown fuse, or a malfunctioning switch. Electrical wiring problems can be complex and potentially dangerous if not handled correctly, so it’s best to have a professional diagnose and fix the issue.

Burning Smell or Smoke

A burning smell or visible smoke when you turn on your lights is a serious warning sign. This could be caused by a short circuit, overheating wires, or other electrical faults. In this situation, turn off your vehicle immediately and seek professional help to prevent further damage or a potential fire.

Repeatedly Blown Fuses

If you find that your vehicle’s fuses keep blowing shortly after replacement, it’s likely due to an underlying electrical problem, such as a short circuit or an overloaded circuit. Continually replacing fuses without addressing the root cause can lead to more extensive damage.

Dashboard Warning Lights

Some vehicles are equipped with dashboard warning lights specifically for the lighting system. If you see a warning light related to your headlights, tail lights, or any other part of your lighting system, it’s important to have it checked out as soon as possible. Ignoring these warnings can compromise your safety and potentially lead to costly repairs down the line.

Aftermarket Modifications

If you’ve installed aftermarket lighting components, such as LED headlights or custom tail lights, and experience any issues, it’s advisable to consult a professional. These modifications can sometimes cause unexpected electrical problems if not installed correctly or if they’re incompatible with your vehicle’s system.

Is It Time For An Inspection?

Something as minor as a headlight or tail light problem can turn into a big deal. Before repairs get you down, schedule an inspection today. It’s the easiest way to ensure everything on your vehicle is working correctly, and will keep you safe no matter where you go on your drive.

The Benefits of Regular Drivetrain Inspections

August 21, 2024 by Denver Express Car Care

You know to change your motor oil every few thousand miles. You know to keep your tires pressurized to ensure they connect with the road. 

But a drivetrain inspection? That might be a bit more fuzzy. What is it, and how does it all work?

What Is a Drivetrain?

Drivetrain is one of those terms that may be referred to in many ways. Driveline is used synonymously, referring to the components that transfer power from the transmission to the wheels. 

Why not call it the transmission system? Some do. In a broad sense, the drivetrain and the transmission system are the same. 

Power train, geartrain, drive system – there are many ways to emphasize different aspects of the drivetrain system. What’s important to note is that it’s what makes your car function. It’s what makes your car go. 

What Makes Up a Drivetrain?

Don’t let the word confuse you. The drivetrain in today’s cars refers to the group of components that work together to deliver power from the engine to the wheels, enabling the vehicle to move. The drivetrain is made up of several components you probably already know. 

Transmission. The transmission is responsible for adjusting the power and torque from the engine, converting it into the appropriate speed and power needed to turn the wheels. You probably have an automatic sitting in the driveway, but manual or continuously variable (CVT) are available too.

Driveshaft. The driveshaft is a rotating shaft that transmits torque from the transmission to the differential. In front-wheel-drive cars, this may be referred to as a half-shaft or axle shaft.

Differential. The differential is a gearbox that splits the engine torque into two outputs, allowing the wheels to rotate at different speeds, which is necessary when turning corners.

The Benefits of Regular Drivetrain Inspections

Axles. Axles connect the differential to the wheels, carrying the load of the vehicle and transmitting the torque from the differential to the wheels.

CV Joints (Constant Velocity Joints). These joints are located at the ends of the driveshafts in front-wheel-drive and all-wheel-drive vehicles, allowing the driveshaft to flex while maintaining constant rotational speed.

Transfer Case (in AWD/4WD vehicles). The transfer case splits the power between the front and rear axles in all-wheel-drive or four-wheel-drive vehicles.

There are dozens of parts that make up each of these systems. They vary based on make and model, or what type of vehicle you drive. 

The drivetrain components are located at the front of the vehicle on front-wheel drive cars, with power being delivered to the front wheels. It’s the opposite with rear-wheel drive, where power is sent to the rear wheels with drivetrain components typically running from front to back. All-wheel and four-wheel drive distributes power to all four wheels, with a transfer case to manage power distribution between the front and rear axles. 

Drivetrain Inspections and Maintenance 

Just looking at the components makes you understand how important it is to care for every part. Without a drivetrain, your car won’t go. 

If you ignore it and hope for the best, you’ll wind up with an inefficient vehicle that faces costly repairs throughout the year. All of that can be avoided with regular maintenance. Here’s what we suggest. 

Quarterly

Or maybe we should say seasonally. As each season passes by on the calendar, it’s a good idea to give your car a visual inspection. 

Check for leaks around the transmission, differential, and transfer case (if applicable).

Inspect the driveshaft, axles, and CV joints for any signs of wear, cracks, or leaks in the rubber boots.

Because the transmission is so important, it’s a good idea to check the transmission fluid level (if your vehicle has a dipstick). Top up if necessary. If your vehicle has a sealed transmission, this step might be skipped or performed by a mechanic during scheduled service.

We also recommend paying attention to any unusual sounds, such as clunking, whining, or grinding noises when driving, especially when accelerating, decelerating, or turning. These noises can indicate issues with the drivetrain components.

Semi-Annual Maintenance 

We suggest taking it a step further every six months. (How about summer and winter?)

Start by checking the transmission fluid condition. Inspect the color and smell of the transmission fluid. It should be a clear red or amber color and not smell burnt. If the fluid is dark or smells burnt, it might be time for a change.

Check the CV boots for any tears or leaks. Damaged CV boots can allow dirt and moisture to enter, leading to joint failure.

For rear-wheel, all-wheel, and four-wheel drives, check the fluid level in the differential. Top up if needed, or schedule a fluid change if it’s due.

For all-wheel and four-wheel drives, ensure the transfer case fluid is at the correct level and in good condition.

Annual Maintenance 

Are you on track with your drivetrain inspections and maintenance? Once a year, we also encourage drivers to schedule an annual inspection to go deeper with drivetrain maintenance. 

How many miles have you put on your vehicle? Your vehicle’s manufacturer may recommend a change for the transmission fluid and filter. This is typically required every 30,000 to 60,000 miles but can vary based on the vehicle and driving conditions.

For vehicles with a differential, change the fluid as per the manufacturer’s recommendations, usually every 30,000 to 60,000 miles.

Change the transfer case fluid according to the manufacturer’s schedule, generally every 30,000 miles, especially for vehicles used in off-road or heavy-duty conditions.

Lubricate the U-joints (if applicable) and inspect the driveshaft for any signs of wear or damage.

Inspect the axle seals and wheel bearings for any leaks or wear. Repack or replace as needed.

Sounds easy, yes? 

Just keep in mind that every vehicle and every drive experience is different. 

Colorado can have harsh winters; inspect the drivetrain components for any signs of wear or leaks before the cold weather sets in, as freezing temperatures can exacerbate existing issues.

If your vehicle is used off-road, drivetrain maintenance may need to be more frequent due to the increased stress on the components and exposure to dirt, water, and other elements.

When Was Your Last Drivetrain Inspection? 

We get, drivetrain inspections might not be at the top of your list. You might not spend much time thinking about your vehicle’s drivetrain at all. But drivetrain inspections will ensure your vehicle is in good working order throughout the year. 

We can help. Inspections are designed to ensure everything is in good working condition. It’s the easiest way to keep you out on the road, getting you where you need to go without worrying about maintenance problems.

The Importance of Regular Car Air Conditioning System Checks

August 14, 2024 by Denver Express Car Care

It’s 90 degrees out, and the thermometer keeps climbing. We’re on track for breaking records this summer. 

Nothing feels better than jumping into your car and feeling a blast of cool air from the vents as you drive down the road. 

But what if your air conditioning system isn’t working? Regular air conditioning checks can ensure you’ll never face the heat with a system that isn’t working. Let’s find out a little bit more. 

Signs Your Car’s Air Conditioning System Is Malfunctioning

Weak Airflow

One of the most common indicators is weak airflow. This happens over time. The air feels weaker or inconsistent, even when the AC is set to its highest setting. Weak airflow often points to problems with the blower fan, which may be worn out or obstructed by debris. It could also indicate a blockage in the air ducts or a failing ventilation system. Over time, dust and debris can accumulate in the AC vents and filters, restricting the flow of air. If left unchecked, weak airflow can lead to more significant issues, reducing the overall efficiency of your car’s AC system and leaving you uncomfortable during your drives.

Warm Air

When your car’s air conditioning system blows warm air instead of cold, it can be a sign of several potential issues. Warm air may indicate low refrigerant levels, which could be due to a leak in the system. The refrigerant is essential for absorbing heat and cooling the air before it reaches the cabin. A faulty compressor is another common cause, as it is responsible for circulating the refrigerant through the system. If the compressor is damaged or not functioning properly, it cannot effectively cool the air. Other causes might include a malfunctioning condenser or an issue with the cooling fans. It’s essential to address this problem quickly, as continued use of the AC under these conditions can lead to more extensive damage to the system.

The Importance of Regular Car Air Conditioning System Checks

Strange Noises

Unusual noises from your car’s air conditioning system can be alarming and are often a sign of mechanical problems. Rattling sounds may indicate loose components or debris caught in the system, while grinding noises can point to issues with the compressor or worn-out bearings. A squealing sound, particularly when the AC is first turned on, might be a sign of a slipping or worn-out belt. These noises are typically due to wear and tear or lack of maintenance, which can cause parts to break down over time. 

Unpleasant Odors

A musty or moldy smell from the air conditioning vents is a clear sign of trouble. This odor often indicates mold or mildew growth within the AC system, usually caused by moisture accumulation. When moisture collects in the evaporator or ducts and isn’t properly drained, it creates an ideal environment for mold to grow. This affects the air quality inside the car, potentially leading to respiratory issues and inefficiency within the system. 

Benefits Of Regular Air Conditioning Checks

Have you noticed a sign that something is wrong with your car’s air conditioner? Have you paid attention? Part of ensuring your air conditioning system is well cared for is performing regular checks. They help you in more ways than one. 

Enhanced Comfort

Regular maintenance ensures your car’s air conditioning system functions efficiently, providing a comfortable and pleasant driving environment. With optimal cooling performance, you’ll enjoy a consistent and refreshing flow of cool air, even during hot weather conditions. This enhances your comfort, making long drives and daily commutes more enjoyable for you and your passengers.

Improved Air Quality

Routine checks and servicing help maintain clean air filters and vents, preventing the buildup of dust, pollen, and other pollutants. This leads to improved air quality inside the car, reducing the risk of respiratory issues and allergies. Clean air filters also prevent unpleasant odors and the growth of mold or bacteria in the system, contributing to a healthier cabin environment.

Increased Fuel Efficiency

A well-maintained air conditioning system operates more efficiently, placing less strain on the engine and improving fuel economy. When the AC system is functioning optimally, it requires less energy to cool the air, resulting in lower fuel consumption. This can lead to cost savings on fuel over time and a reduced environmental impact.

Prevention of Major Repairs

Regular inspections can identify minor issues before they develop into major problems, helping to prevent costly repairs. By addressing issues such as refrigerant leaks, worn-out components, or electrical malfunctions early on, you can avoid more extensive damage that might require expensive repairs or replacements.

Extended System Lifespan

Regular maintenance helps extend the lifespan of your car’s air conditioning system by keeping all components in good working condition. By ensuring that parts like the compressor, condenser, and evaporator are functioning properly, you can prolong the overall durability and reliability of the system, saving money on premature replacements.

Better System Performance

Routine checks and servicing ensure that all components of the AC system are operating at their best, leading to improved overall performance. This means faster cooling, consistent temperature regulation, and better dehumidification, all of which contribute to a more effective air conditioning system.

Safety and Reliability

A properly functioning air conditioning system enhances safety by preventing foggy windows and ensuring clear visibility. Regular checks can also prevent unexpected breakdowns and failures, ensuring that your AC system remains reliable when you need it most, especially during extreme weather conditions.

Preservation of Vehicle Value

Keeping your car’s air conditioning system in top condition helps preserve the overall value of your vehicle. A well-maintained AC system is an attractive feature for potential buyers and can contribute to a higher resale value when it comes time to sell or trade in your car.

How to Choose the Right Coolant for Your Vehicle

August 7, 2024 by Denver Express Car Care

When you visit the gas station, do you pay attention to the fuel pumped into your vehicle? Of course. You select a gas station you trust. You select the right fuel – regular, premium, diesel? You know it makes a difference because you feel it in the way your car drives. 

What about motor oil? You have it on the calendar to replace every few thousand miles. You have an auto repair shop that’s done a good job in the past. Your car is running well – why mess with success!?

Did you know an engine’s coolant is equally as important as your gas or motor oil?

In the summer, coolant raises the boiling point of the cooling system. In the winter, it lowers the freezing point and protects the engine and cooling system from corrosion. This means your engine is protected from overheating or freezing when driving in those sweltering or freezing temperatures. 

But here’s the thing: coolant is not a once-and-done fluid. It needs maintenance just like your motor oil. As coolant ages, it breaks down and becomes less effective over time. When this happens, it impacts many other components in your vehicle. 

When you decide it’s time for maintenance, choosing the right coolant might not be top of mind. Maybe it should be. 

Why Does Your Car Need Coolant?

Coolant is a fluid that circulates through a car’s engine to regulate its temperature. You might also know it as antifreeze. It’s typically a mixture of water and ethylene glycol (or sometimes propylene glycol), which helps prevent the liquid from freezing in cold temperatures or boiling over in high temperatures. 

When you look at it, you’ll notice coolant often comes in different colors like green, yellow, pink, or orange, depending on the type and manufacturer. Why does your car need it? Several reasons. 

How to Choose the Right Coolant for Your Vehicle
  • Temperature Regulation: The primary function of coolant is to absorb heat from the engine and disperse it through the radiator, preventing the engine from overheating. An engine that runs too hot can suffer severe damage, including warped components and a potential engine failure.
  • Prevents Freezing: In cold climates, the coolant prevents the liquid in the engine from freezing. If the coolant were to freeze, it could expand and crack the engine block, causing significant damage.
  • Corrosion Protection: Modern coolants contain additives that help protect the engine’s internal components from corrosion, rust, and scale build-up. This prolongs the life of the engine and ensures it operates efficiently.
  • Lubrication: Coolant also helps lubricate the moving parts it comes into contact with, such as the water pump, ensuring they function smoothly and reducing wear and tear.
  • Maintains Pressure: Coolant helps maintain proper pressure within the cooling system, which is crucial for the system’s effectiveness. The coolant raises the boiling point of the water in the engine, allowing the engine to run hotter without boiling over, which improves efficiency.

There Are Several Different Types Of Coolant

We don’t live in a world with only one make and model of vehicle. Each manufacturer designs its vehicles with specific guidelines in place. That’s why several different types of coolant are available to meet the specific needs and manufacturers requirements. 

While there are many different types of coolant, the most common types include:

  • Inorganic Acid Technology (IAT) Coolant: This is the green coolant you might find in older cars made before the mid-1990s. It needs to be changed every 2-3 years or 30,000 miles.
  • Organic Acid Technology (OAT) Coolant: Often orange, but it can also be green, pink, or red. This type is used in many modern cars, like GM vehicles. It lasts longer—up to 5 years or 150,000 miles.
  • Hybrid Organic Acid Technology (HOAT) Coolant: Usually yellow or orange, this coolant combines the benefits of IAT and OAT coolants. You’ll find it in cars from brands like Ford and Chrysler, and it also lasts about 5 years or 150,000 miles.
  • Phosphate-Free Organic Acid Technology (P-OAT) Coolant: Typically blue or pink, this coolant is common in European and Asian cars, like BMW and Mercedes-Benz. It’s designed to last up to 5 years or 150,000 miles.
  • Nitrate Organic Acid Technology (NOAT) Coolant: Purple or pink, this is mainly for heavy-duty vehicles, like trucks and diesel engines. It provides extra protection against specific types of wear and lasts a long time.
  • G-05 Coolant: This yellow or gold coolant is used in some Ford, Chrysler, and Mercedes-Benz vehicles. Like HOAT coolants, it’s good for about 5 years or 150,000 miles.
  • Si-OAT Coolant: Often purple or pink, this type is found in many European cars, like Audi and Volkswagen. It’s especially good for modern engines and also lasts up to 5 years or 150,000 miles.

How Do You Know Which Coolant To Use In Your Car?

Just like motor oil, coolant is necessary to keep your car running well. Which should you use? Luckily, this isn’t something you have to run to the market and pick out on the shelves. There are many ways to select the right coolant your car needs to keep your engine running smoothly and avoid potential damage. 

Check Your Vehicle’s Owner’s Manual

The best place to start is your vehicle’s owner’s manual. It will specify the type of coolant recommended by the manufacturer. This recommendation is based on your car’s engine design and materials, so it’s crucial to follow it.

Look for Manufacturer-Specific Coolants

Some car manufacturers, like GM, Ford, or European brands like BMW and Mercedes-Benz, require specific types of coolant that match their vehicles’ cooling systems. These coolants often have brand-specific names, like “Dex-Cool” for GM vehicles. Using the coolant recommended by the manufacturer ensures optimal performance and avoids warranty issues.

Consider the Age and Type of Your Vehicle

Older vehicles, especially those made before the mid-1990s, typically use Inorganic Acid Technology (IAT) coolant, which is often green. Modern vehicles generally require Organic Acid Technology (OAT), Hybrid Organic Acid Technology (HOAT), or other advanced types of coolant. These are usually longer-lasting and provide better protection against corrosion.

Pay Attention to the Coolant Color

While color can be a helpful guide, it’s not foolproof. Different types of coolant can be the same color, so it’s not a reliable indicator on its own. Always cross-check the type of coolant with what your car’s manual specifies.

Avoid Mixing Different Types of Coolant

Mixing different coolants can lead to chemical reactions that reduce the coolant’s effectiveness or cause engine damage. If you’re switching coolant types (e.g., from IAT to OAT), it’s often necessary to completely flush the system first to avoid mixing.

Consult a Professional

If you’re unsure, it’s always a good idea to consult a mechanic or the dealership. They can provide guidance on the right coolant for your car and even perform a coolant flush if needed.

Use Online Resources

Many coolant brands provide compatibility charts or tools on their websites where you can enter your vehicle’s make, model, and year to find the right coolant.

Better yet, find an auto repair shop you can trust. 

They will inspect your coolant whenever you bring your car in for inspection. And when necessary, they will choose the right coolant for your car and replace it for efficiency. 

It’s the best way to ensure your car stays protected against temperature extremes and corrosion.

Minor Fender Bender? Don’t Forget Auto Repair

July 28, 2024 by Denver Express Car Care

Minor fender benders are a part of driving. No matter how careful you are out on the road, at some point you’ll experience minor mishaps. 

Fender benders are usually minor accidents that happen at slower speeds or even while parked. When you hop out and take a look at your car, it might not look like much. You might not notice anything at all. 

But this is your car. And safety should always be number one priority.  

Whether it’s a tap as you’re pulling out of a parking space, or a minor altercation out on the road, your first step is to ensure safety. That means bringing it in and allowing a trained mechanic to inspect it and fix anything that may impact your drive. 

Alignment Issues

Alignment issues might not be immediately apparent to the naked eye, but they can lead to significant problems over time. It can cause:

  • Wheel misalignment – small impacts can shift the wheels out of alignment, causing your car to pull to one side. 
  • Suspension damage – any of the suspension components – control arms, shocks, struts – can be damaged or bent. 
  • Tires – when your wheels are misaligned, it often leads to uneven tire wear. This can reduce tire life and affect your vehicle handling. 
  • Steering – fender benders can affect the steering wheel position, causing it to be off-center even if it appears to be driving straight.
  • Vibrations – misalignment can cause vibrations when driving at higher speeds. If it’s shaking and rattling, it can impact many components throughout your vehicle. 

One of our mechanics will first visually inspect the suspension components, tires, and steering system for obvious signs of damage or wear. Using alignment equipment, the mechanic will measure the angles of the wheels to see if they meet the manufacturer’s specifications.

Minor Fender Bender? Don’t Forget Auto Repair

Then we’ll inspect suspension parts such as control arms, tie rods, shocks, and struts for bends, cracks, or other damage. The tires will be checked for uneven wear patterns, which are indicative of alignment issues. The steering rack, tie rods, and other related components will be examined for damage or wear.

Whew – that’s a lot that could be potentially wrong, and you didn’t even see it!

Engine Problems

A lot of things can happen in the engine compartment that aren’t immediately visible. Yet the engine is one of the most essential systems! A fender bender can cause:

  • Radiator and cooling system damage – the impact from your fender bender can cause the radiator to crack or develop leaks, which can lead to overheating.
  • Hoses and belts – the force of the collision can dislodge or damage hoses and belts connected to the engine, leading to leaks or loss of function.
  • Fluid leaks – engine oil, transmission fluid, coolant, or other vital fluids can leak from damaged reservoirs or lines.
  • Electrical components – sensors and wiring can be jarred loose or damaged, causing malfunctions in engine management systems.
  • Engine mounts – the mounts that secure the engine to the chassis can be cracked or broken, leading to misalignment and vibration.
  • Air intake and exhaust – the air intake system or exhaust components can be damaged, affecting engine performance and emissions.

One of our mechanics will perform a thorough visual check of the engine bay for apparent signs of damage, leaks, or dislodged components. Then we’ll move to checking the levels and condition of engine oil, coolant, transmission fluid, and other fluids to ensure there are no leaks or contamination. Then it’s on to inspecting the radiator, hoses, and cooling fans for damage or leaks that could affect engine temperature regulation.

Using diagnostic tools, we’ll check for any faults in the sensors, wiring, or other electronic components connected to the engine. We’ll inspect all belts and hoses for wear, damage, or displacement, and the engine mounts for cracks, breaks, or signs of shifting. We’ll ensure the air intake is clear of obstructions and the exhaust system is intact and functioning properly.

You can’t drive if your engine isn’t in proper working condition. We won’t let you drive away until it’s all inspected. 

Electrical System Damage

Sometimes it’s not about the structure. You notice problems with your lights, or the way your car turns on, or your windows won’t roll down. There’s a lot in your vehicle connected to the electrical system. That tiny nudge from behind might have knocked something loose. 

  • Sensor damage – a minor impact can damage or dislodge sensors like those for airbags, ABS, parking assistance, and more.
  • Wiring harness damage – wires can be pinched, cut, or disconnected, leading to electrical shorts or open circuits.
  • Battery and alternator issues – the jolt from the collision can damage the battery or alternator, affecting the vehicle’s electrical supply.
  • Fuses and relays – the impact might cause fuses to blow or relays to malfunction, leading to loss of power to certain systems.
  • Lighting damage – headlights, tail lights, and indicator lights can be damaged or dislodged, causing them to malfunction.
  • Control modules – the collision can affect electronic control modules (ECMs) that manage various vehicle systems, causing erratic behavior.

And this is just the start. Many drivers don’t realize how much of their vehicle is controlled by the electrical system … until it doesn’t work. We understand this and will test and inspect to ensure everything is working. 

We’ll perform a thorough check of the engine bay, undercarriage, and interior for any obvious signs of electrical damage or dislodged components. Using an OBD-II scanner to read any error codes from the vehicle’s computer systems, we’ll look for any indicators of specific problems. We’ll check the condition of wiring harnesses for any signs of wear, pinching, or disconnection.

Then we’ll test sensors related to critical systems like airbags, ABS, and parking assistance to ensure they function correctly. We’ll test the battery and alternator to ensure they are providing proper power and charging correctly. We’ll inspect and test fuses and relays to ensure they are intact and functioning as they should. We’ll check all external and internal lights to ensure they are operational.

You might not realize just how much of a car is controlled by the electrical system. Don’t worry; we’ve got you covered. 

Have a Fender Bender? Don’t Worry!

We understand any accident can be worrisome. But you’re safe. Your passengers are safe. Now it’s time to ensure your vehicle is safe too. 

Even if you aren’t bringing it in for auto body repair, it’s still worth your time to let one of our mechanics give it a lookover. We’ll inspect it and check everything out so you can get back on the road safely and securely. 

It’s all about peace of mind.

Towing a Vehicle – Your Car Needs More Maintenance 

July 24, 2024 by Denver Express Car Care

Ahh, summertime. You’ve been dreaming about it all year. You’ve purchased a bigger vehicle, have the boat on a trailer or jet skis ready to go. Now all you need to do is hook everything together and take off for summertime fun. 

But what about your vehicle? Is it ready for towing, especially here in Colorado where you might be towing it into the mountains? Or should you take your vehicle in for maintenance to ensure it’s ready for the road trip ahead?

It’s great to think ahead. Because towing can be strenuous, especially if your vehicle isn’t up for the job. 

How Towing Impacts Your Vehicle

What does towing do to your vehicle? Let’s look at your body as comparison. What happens after spending a morning in the garden? After pushing and pulling all sorts of equipment, how did you feel? Your back aches. Your fingers are numb. You can feel it in every muscle in your body. 

In similar fashion, towing forces your car to use components in ways they don’t normally operate. It can increase wear and tear, especially the more you tow. Of course, there are a lot of influences – how old is your car, how big is the engine, what about the tire capacity, and more. 

Just a few of the components that can be affected by towing include:

Towing a Vehicle - Your Car Needs More Maintenance 

Transmission

Towing can have a significant impact on the transmission, which has to work much harder to handle the extra load. This can cause the transmission to overheat, wear out faster, and, in severe cases, fail completely. 

Brakes 

Brakes also take a hit when towing. The additional weight means your brakes have to work harder to stop the vehicle, which can lead to faster wear of brake pads and rotors, increased brake temperatures, and even brake fade, where the brakes lose effectiveness. 

Suspension 

The suspension system bears the extra load too. Components like shocks, struts, and springs experience increased stress, which can result in premature wear and a rougher ride. 

Tires 

Don’t forget about the tires. The extra weight increases the load on your tires, leading to faster wear and a higher risk of blowouts. This also negatively impacts fuel efficiency. 

Engine 

All of this extra pulling means your engine also has to work much harder when towing. This can lead to increased wear, higher operating temperatures, and potentially reduced engine life. 

Cooling system

The cooling system has to handle more heat generated by the engine and transmission during towing. This added strain can cause the engine to overheat if the cooling system is not in top condition. 

Drivetrain 

Imagine the stress the drivetrain endures as you pull your favorite toys into the hills. This can include the driveshaft, axles, and differential. These parts experience higher levels of stress, leading to increased wear and potential failure. 

Frame 

The vehicle’s frame and hitch components carry the weight and force of the towed load. Over time, this can cause frame stress and potential deformation. 

Fuel economy 

Lastly, towing increases aerodynamic drag and vehicle weight, which leads to higher fuel consumption and reduced fuel economy. To mitigate the impacts of towing, regular maintenance, proper equipment, careful driving, and balanced load distribution are essential.

Understanding Towing Capacity

You have a truck or an SUV. You also have a boat or a camper. You can’t just hook one to the other without understanding towing capacity. Have you ever heard phrases like “payload capacity” or ‘towing capacity?” 

Towing capacity is the maximum weight your vehicle can safely tow, including the trailer and its cargo. This capacity varies between vehicles and is determined by the manufacturer based on factors like the engine, transmission, brakes, and suspension system.

How do you find your vehicle’s towing capacity?

  • Check the Owner’s Manual: Manufacturer specifications are listed here.
  • Look for a Label: Some vehicles have a label inside the driver’s door with the towing capacity.
  • Online Resources: Visit the manufacturer’s website or reliable automotive sites for information.

Ready To Tow – Maintenance Items To Ensure You’re Always Ready

The thing about living in Colorado is there are always opportunities to take off and enjoy nature. Summer, winter, spring, or fall, tow all of your toys just a handful of miles from home, and enjoy all Colorado has to offer. 

To do so, keep your vehicle in good operating condition, to be ready for whenever you decide to hit the road. 

Start with your engine and transmission. Ensure you follow the recommended oil change intervals, especially before towing. Consider using high-quality or synthetic oil for better protection under stress. Check the transmission fluid regularly and replace it as needed. Clean, fresh fluid helps the transmission run cooler and more efficiently, which is crucial when towing.

Because the cooling system is critical, inspect the radiator for leaks and ensure the coolant level is adequate. Flush and replace the coolant according to the manufacturer’s recommendations to prevent overheating. Check all hoses and belts for signs of wear, cracks, or leaks. Replace them if they show any signs of damage to avoid unexpected breakdowns.

Can you imagine navigating the open road without working brakes? Inspect brake pads and rotors for wear and replace them if necessary. Towing puts extra strain on the brakes, so they need to be in top condition. Check the brake fluid level and quality. Replace it if it’s dark or has debris, as fresh brake fluid ensures optimal braking performance.

Just as important is your suspension system. Inspect the shocks and struts for leaks or damage. Replace them if they’re worn out to maintain a smooth ride and proper handling. Check the condition of the springs. Heavy loads can wear them out faster, so replace any that are sagging or broken.

Your tires will wear out faster too. Ensure all tires, including the spare, are properly inflated to the recommended pressure. Inspect tire tread for even wear and sufficient depth. Replace any tires that are worn out or damaged.

More gadgets mean more stress on your electrical system. Check the battery’s condition and ensure it’s fully charged. Towing can put extra demand on the electrical system, so a healthy battery is essential. Inspect all wiring and electrical connections, especially those related to trailer lights and brakes, to ensure they are secure and in good working order.

We also recommend keeping an eye on your drivetrain. Check the differential fluid level and quality. Replace it according to the manufacturer’s schedule to ensure smooth operation. Inspect the drive shaft and axles for wear and lubrication. Replace any worn or damaged components.

Before heading out, check your vehicle’s overall condition. Take a walk around for visual inspections to catch any potential issues early. Consider getting a professional mechanic to perform a thorough inspection and maintenance check before any major towing trip.

It’s the best way to ensure you’re safe and your vehicle is ready to tow. 

Can we help you get ready for your next vacation?

Understanding the Signs of Transmission Problems and How to Fix Them

July 21, 2024 by Denver Express Car Care

Imagine your life without your car. Hard to do, isn’t it?

You jump behind the wheel in the morning, and it’s go-go all day. You start it and stop it. You brake for lights and stop signs. You throw it into gear as you drive away. You put it into reverse as you back out of parking spaces. 

But what if you notice a problem? What if you try to put it into gear and it slips? Or refuses to switch gears? 

That’s a sign of transmission problems. 

What Is A Transmission?

In simple terms, a transmission is a mechanical component that transmits power from the engine to the wheels. Its primary function is to ensure that the engine operates within an optimal range of speeds while providing a range of output speeds to the wheels. This allows the vehicle to accelerate smoothly from a standstill to high speeds and to operate efficiently under various driving conditions.

Today, we almost always operate with automatic transmissions. This is where the vehicle automatically changes gears based on speed and engine load without the driver needing to intervene.

If you drive a sports car or an older vehicle, you might have driven with a manual transmission. This is where the driver manually shifts gears using a clutch and gear stick. Continuously variable transmissions and dual-clutch transmissions exist too, though they aren’t as common. 

Understanding the Signs of Transmission Problems and How to Fix Them

Signs Of Transmission Problems  

Transmissions work … until they don’t. Luckily, transmission failure doesn’t usually happen without warning. 

Listen to your car. Pay attention. It rarely goes from working to nothing without warning. 

Noises

This is one of the most popular ways people start to notice problems. They turn the key, they put it in drive, and hear something unusual. When you know how your car usually sounds, it’s easy to pick up when things don’t sound quite right. 

Don’t ignore these sounds. Clunking, humming, or whining are all indicators of automatic transmission problems. If you notice it when your car is shifting gears, it is a clear indicator of problems. It’s time for a mechanic to look it over. 

Smells

What’s that smell? If it seems to be coming from your engine compartment, it’s a sure sign of a problem. As transmission fluid runs low or wears down, it overheats and starts to burn. It can create a burning smell that’s hard to ignore. The longer it operates under these conditions, the more damage will occur with your engine. A hot engine contributes to early wear and corrosion. 

Of course, smells can come from many places. Maybe a trapped plastic bag made its way up and melted inside the engine compartment. Maybe dripping antifreeze is causing a problem. Whatever the case, treat the smell as a problem, and get it checked out quickly. 

Check Engine Light

There can be dozens of little lights on your dashboard, all blinking for your attention. Each of them means something different. But the check engine light is often the one that confuses people the most. It can tell you the gas cap is loose, you have a faulty oxygen sensor, or you have transmission problems. Big difference, right?

If the transmission is triggering a dashboard icon, it’s sensing jerks and tremors you might not notice until later. It’s picking up these subtle changes, alerting you to potential problems. If you get it checked quickly, it might remain a minor problem, and be an easier, less expensive fix. 

Shifting Problems

When your car is working correctly, it slides into gear every time you adjust the gears. Problems arise when you notice that the slide isn’t working quite the way it used to. It hesitates. It gives you no response. Ignore this, and there may come a time when the transmission leaves you stranded, without being able to get it into gear. 

Fluid Leaks

Your vehicle has several essential fluids to keep it operating and lubricated. If fluids break down or start to leak, the system weakens and eventually becomes inoperable. 

A transmission fluid leak is easy to spot. It has a unique red color and sweet smell. If it’s degrading, it will take on a darker red color and start to have a toasted smell. 

This is something you can easily watch for yourself. Take a look at your driveway as you drive away. If you see the red color, your transmission fluid is leaking. It’s time to bring it in right away. 

Won’t Go Into Gear

You go to move from park to reverse or drive, and it refuses to go into gear. It’s often a fluid issue. If the fluid is clean, it might be a problem with the shift cables or clutch. The computer system could also be the issue. 

If it is the computer system, you can give your car a reboot. Disconnect the battery for a few minutes, and the computer reboots once it’s reengaged. If you still have a problem, it’s one of the others. You’ll need to get your car into see one of our mechanics to fix the problem. 

Slipping Gears

With a manual transmission, you, the driver, change gears. With an automatic, you can choose reverse, neutral, or drive, then the transmission handles the rest. 

If your car is slipping between gears without any change from you, it’s dangerous for you and the engine. This could be caused by low fluids or worn down transmission components that are allowing the gear to slip. Get your vehicle into our repair shop to avoid dangerous situations. 

Pay Attention and Don’t Miss These Transmission Problems

If you’ve noticed any of these transmission problems, it’s time to get it checked out. Whether you hear it, smell it, or notice it as you drive, don’t put it off. Minor problems can be easier and less expensive to fix. Bigger problems risk leaving you stranded by the side of the road. 

Have questions? We’re here to help. Come in today and we’ll help you get to the root of the problem.
