Why Regular Oil Changes are Essential for Your Vehicle

July 3, 2024 by Denver Express Car Care

You’re familiar with the advice about regular oil changes. It’s why oil changes are the most frequent maintenance items performed on today’s vehicles. 

What you aren’t sure about is the why. 

They say to replace oil every 3,000 to 5,000 miles. Some push it to 7,500 or 10,000. But what’s really true? Are regular oil changes essential to the health of your vehicle? What should you keep in mind as you go about your errands each day?

Why Your Car Needs Motor Oil

Your car’s engine needs motor oil to keep it running smoothly. It provides lubrication. Without it, the moving parts inside the engine couldn’t glide together without causing damage. They would grind, creating a lot of friction and wear. 

Motor oil also plays a crucial role in cooling the engine. As the engine runs, it gets hot, and the oil helps carry away this heat. This keeps the engine from overheating and maintains the right temperature for proper operation.

This role means motor oil gets pushed to the limit as you drive each day. Luckily, manufacturers realize this, and have built special additives into motor oil to pick up debris, and sludge, preventing them from building up inside the engine. This keeps the engine clean and running efficiently.

Without motor oil, an engine could face corrosion. Motor oil forms a protective layer on engine parts, preventing rust and damage caused by moisture and other elements. This is vital for keeping the engine in good condition.  It seals the engine, filling the tiny gaps between the piston rings and cylinder walls, ensuring efficient compression and combustion. This improves how the engine performs and helps save on fuel.

Why Regular Oil Changes are Essential for Your Vehicle

And if all that wasn’t enough, it also acts as a shock absorber. It cushions the engine’s moving parts, reducing the noise and vibration you might feel while driving. This makes your ride smoother and quieter.

What’s In Regular Motor Oil That Makes It Essential For Your Vehicle

Motor oil is essential to keep your car’s engine performing throughout the years. But what’s even more important is understanding what’s inside. 

The primary component of motor oil is the base oil, which makes up about 70-90 percent of the oil. Base oils can be made from petroleum, synthetic chemicals, or a blend of both. They provide the basic lubrication properties needed to reduce friction and wear in the engine.

The remaining 10-30 percent of motor oil consists of additives that enhance the performance of the base oil. These additives include:

Detergents

Detergents keep the engine clean by preventing the formation of deposits, sludge, and varnish on engine parts. They help remove impurities and keep them suspended in the oil until the next oil change.

Dispersants

Dispersants help keep solid contaminants in suspension, preventing them from clumping together and forming sludge. This ensures that the contaminants are carried to the oil filter, where they can be removed from circulation.

Anti-Wear Agents

Anti-wear agents, such as zinc dialkyl dithiophosphate (ZDDP), form a protective film on engine parts. This film reduces metal-to-metal contact, thereby minimizing wear and extending the life of engine components.

Viscosity Index Improvers

These additives help the oil maintain its viscosity, or thickness, across a wide range of temperatures. This ensures that the oil flows easily at low temperatures while remaining thick enough to provide adequate lubrication at high temperatures.

Antioxidants

Antioxidants prevent the oil from oxidizing, or breaking down, under high temperatures. Oxidation can lead to the formation of sludge and varnish, which can harm the engine. By preventing oxidation, antioxidants help prolong the life of the oil.

Corrosion Inhibitors

Corrosion inhibitors protect the engine parts from rust and corrosion caused by moisture and acidic by-products of combustion. This protection helps maintain the integrity of engine components.

Friction Modifiers

Friction modifiers reduce friction between moving parts, improving fuel efficiency and reducing wear. They are particularly important in modern engines designed for high performance and fuel economy.

Foam Inhibitors

Foam inhibitors prevent the formation of foam and air bubbles in the oil. Foam can reduce the oil’s effectiveness in lubricating and cooling the engine, so these inhibitors ensure consistent performance.

What Makes Today’s Motor Oil Different From Yesteryear?

Motor oil has been used since the dawn of cars. Maybe you remember your dad performing an oil change himself – it seemed easy. Just a can of oil, and you’re on your way. 

Things have changed a bit over the years. Today’s motor oil significantly differs from the oil used in the past. 

Modern motor oils often include synthetic base oils, which are chemically engineered to provide superior performance compared to conventional petroleum-based oils. Synthetic oils offer better stability, reduced volatility, and enhanced performance at extreme temperatures. Even conventional oils have seen improvements in refining processes, resulting in cleaner, more stable base oils that perform better and last longer.

Today’s motor oils also contain a more sophisticated blend of additives designed to meet the specific needs of modern engines. These include advanced detergents, dispersants, anti-wear agents, antioxidants, and friction modifiers that provide better protection and performance. Additives are now tailored to meet the requirements of different types of engines, including turbocharged, direct-injection, and high-performance engines.

Modern oils are typically multi-grade, meaning they can perform well across a wide range of temperatures. This is achieved through viscosity index improvers that allow the oil to remain fluid in cold temperatures while maintaining its thickness in hot conditions. They are more stable and less prone to breaking down or thinning out under extreme conditions, providing consistent lubrication and protection.

Modern motor oils meet stringent standards set by organizations like the American Petroleum Institute (API) and the European Automobile Manufacturers’ Association (ACEA). These standards ensure that the oils provide adequate protection and performance for modern engines. Many motor oils are also formulated to meet the specific requirements of Original Equipment Manufacturers (OEMs), ensuring compatibility and optimal performance for specific vehicle brands and models.

There is a growing market for biodegradable and eco-friendly motor oils that are less harmful to the environment. These oils are designed to minimize the ecological impact without sacrificing performance.

That’s Why Regular Oil Changes Are More Important Than Ever

It’s easy to put off regular maintenance. You get busy. Life happens. And suddenly, you can’t remember the last time you brought your vehicle in for servicing. 

But there’s a reason it can’t wait. Your engine is at the heart of your vehicle. If it’s compromised, it can have a ripple effect throughout your vehicle. 

Want to increase longevity? Want your vehicle to continue running smoothly? Start with a regular oil change. 

It’s the start of keeping your vehicle in the best shape possible.

The Benefits of Scheduling Regular Auto Maintenance Appointments

June 28, 2024 by Denver Express Car Care

When you want in-depth investigation, the best place to go is to the source. For your car, it would be your owner’s manual.

An owner’s manual is crafted from the very people who designed and manufactured your car. They understand how to keep everything in good working condition because they are the ones who picked the parts and put them together. 

This isn’t an easy feat. If you own an Audi R8, it would take you 43 hours to read through the more than 616,064 words. Have a Jeep Gladiator? It’s a mere 11 hours at 158,194 words. And for some, you’ll need a university-level education to fully understand what they’re talking about. Not a car buff? You might drift off a few pages in. 

But if you can’t understand it and don’t have the time to dive in, how do you know the best way to take care of your car? It’s one of your biggest investments; maintaining it should be top priority. 

Luckily, there’s an easier way than taking vacation days to fully absorb manufacturer’s guidelines. Rely on regular auto maintenance visits with your local auto mechanic instead. 

The Benefits of Scheduling Regular Auto Maintenance Appointments

Your Car’s Starting Point

Every new vehicle starts out with a warranty. If your car is less than three years old and has fewer than 36,000 miles, which is the average warranty for new cars, you’re probably covered. This means you can take a trip back to the dealer and they will cover whatever the warranty covers. 

This doesn’t cover wear items like brake pads or oil changes. Your car will still need “routine maintenance” – those items you’ll pay for no matter where you are in your warranty period. 

This starts out with tasks that need to be performed regularly. They keep your car in good working condition. Oil changes, tire rotation, brake pad inspection, and fluid checks are a good place to start. They become even more imperative after your warranty runs out. 

Scheduling Regular Auto Maintenance Visits

The older your car gets, the more maintenance it will need to stay in good operating condition. This is where owners can take one of two roads. 

The first schedules regular auto maintenance visits, choosing to handle routine maintenance items before they turn into bigger repair problems. They work proactively to ensure their vehicles are always in the best condition possible. 

The second avoids regular maintenance and only brings a vehicle in when it’s no longer working. They work on the “emergency only” philosophy, and believe in saving money rather than spending money on routines. 

Obviously, it’s easy to see which method is better for your car and for your wallet. Staying on top of auto maintenance visits will benefit you in several ways:

  • It prevents major breakdowns. Regular check-ups can identify potential issues before they become major problems. If you fix small issues early, it will prevent costly repairs down the line.
  • It improves safety. Routine maintenance ensures that essential safety components such as brakes, tires, and suspension are in good working order, which in turn reduces the risk of accidents.
  • It enhances fuel efficiency. A well-maintained car runs more efficiently, consuming less fuel. Regular oil changes, air filter replacements, and proper tire inflation can improve gas mileage, saving you money at the pump.
  • It maintains the warranty. Many car warranties require regular maintenance to remain valid. If you stick to the recommended maintenance schedule, it can protect you from losing warranty coverage.
  • It increases resale value. A car with a documented history of regular maintenance is more attractive to buyers and can command a higher resale price. If you tell potential buyers you have a record of regular maintenance, they will be more confident that the vehicle has been well cared for.
  • It extends the vehicle’s lifespan. Routine maintenance helps your car run smoothly and efficiently for a longer period. This means you can enjoy your vehicle for more years without needing to invest in a new one prematurely.
  • It avoids unexpected breakdowns. Nothing is worse than being broken down by the side of the road. Regular maintenance can reduce the chances of unexpected car trouble, which can be inconvenient and expensive. Isn’t it nice knowing that your car is reliable and ready for any journey?
  • It has better performance. Regular tune-ups keep your car’s engine running at its best. Clean spark plugs, fresh fluids, and proper tire alignment contribute to a smoother, more enjoyable driving experience.
  • It’s cost-effective. While routine maintenance does have a cost, it is generally much cheaper than emergency repairs. Catching issues early often means simpler, less expensive fixes.
  • It gives you peace of mind. Knowing that your car is in good condition can provide peace of mind, especially during long trips or daily commutes. You can drive with confidence, knowing that your vehicle is less likely to encounter problems.

Consult With Your Mechanic

When it comes to keeping your car in good working condition, there are general guidelines or rules of thumb to your approach.

Monthly or every 5,000 miles

  • Check oil and coolant levels
  • Inspect tire pressure and tread depth
  • Check windshield washer fluid level
  • Inspect belts and hoses for signs of wear

Before a road trip

  • Check tire pressure and tread depth
  • Inspect brakes and brake pads
  • Check fluid levels – oil, coolant, transmission, power steering, and brake fluid
  • Inspect belts and hoses for signs of wear

Once a year or every 30,000 miles

  • Spark plug replacement
  • Air filter replacement
  • Fuel filter replacement
  • Belt checks and replacement
  • System checks – brake, transmission, engine, suspension, electrical, exhaust, fuel

Again, this varies by manufacturer, make, and model. Instead of looking at your owner’s manual, a better choice might be to partner up with an auto mechanic you can trust. Together they can help you establish a regular maintenance schedule that works for your lifestyle. 

It’s the best way to keep your car in good working condition, for life.

How to Extend the Lifespan of Your Vehicle

June 21, 2024 by Denver Express Car Care

What’s the secret to extending your vehicle’s lifespan? 

There isn’t one thing you can do. Instead, it’s a series of little things you choose to do every day that over a lifetime add up. 

While you can make the most difference if you start with a new car from day one, even an older car can become more reliable if you make changes and keep it well-maintained. 

Research shows that burning one gallon of gas emits 8,887 grams of CO2. For a standard midsize car that travels 12,000 miles, it emits 11,000 pounds of CO2. 

What if you could make a difference in how your car operates? What if it also extended your car’s lifespan? Win/win! This is how you do it. 

Create a Maintenance Schedule and Stick To It

There’s a reason the advice of replacing your motor oil every 3,000 to 5,000 miles is drilled into you … It works. If you bring fresh oil into your car’s engine every few thousand miles, your car is less likely to have problems over time. Parts will stay lubricated. Motor oil will flow without issue. And your engine will stay safe no matter what the drive holds for the day. 

How to Extend the Lifespan of Your Vehicle

But it’s not just your motor oil in question. It’s every part that comes together and makes your car run well. 

Regular maintenance means topping off or replacing fluids. Replacing oil and air filters. Checking brake pads and replacing them periodically. Checking your suspension and steering. Keeping tire pressure at proper levels. 

It’s all of this and more. 

Your owner’s manual is a great place to start. It can give you a checklist of when you should look at each system, each part. If you can’t find it, you’ll find it online. A quick search will lead you to a wealth of information about your vehicle’s make and model. 

Be sure to keep records of all work you’ve had done, and hang onto your receipts. In some cases, they can provide valuable information about the history of your car. This can also be a bonus if you sell a car – people pay extra for cars with a proven track record. 

Make It A Habit To Check Your Fluids

Your car has a bunch of different fluids in it that make your car go. 

  • Motor oil lubricates and cools the engine components.
  • Transmission fluid lubricates the gears and provides hydraulic pressure for automatic transmissions.
  • Coolant or antifreeze regulates the engine’s temperature and prevents overheating. 
  • Brake fluid transfers force from the brake pedal to the brake pads, enabling the braking process to occur. 
  • Power steering fluid provides hydraulic assistance to make steering easier. 
  • Differential fluid lubricates the differential gears. 
  • Windshield washer fluid cleans the windshield for clear visibility.
  • Fuel powers the engine and makes your car go. 

You can’t make a car go without gas. That’s one fluid every driver knows to put in or pay the consequences somewhere out on the road. Pay attention to quality, selecting reputable servicing stations that offer quality gas. It makes a difference. 

The other fluids may not be as regular or as noticeable, but they are equally important. This isn’t something you have to check yourself. Scheduling a regular maintenance visit with one of our mechanics will ensure every system in your vehicle is ready to go. 

Drive Safely Every Day

This may seem obvious, but it goes a lot deeper than keeping your eyes on the road. The more care you put into your drive, the more you’ll see it show up in a reliable car that doesn’t slow you down when you least expect it. 

It starts by doing a “flight check” every time you drive. When you start up your car, does it sound right? Do you notice lights on the dashboard, noises that you’ve never heard before, or smells you know aren’t quite right? Don’t ignore any warning signs. You can see if it repeats throughout the day, but if it does and you notice it continually, it’s a sign to schedule a maintenance visit. 

Then, become a more considerate driver. Don’t race your car’s engine when you start, especially if it’s cold outside. Accelerate slowly as you begin to drive, giving your car a chance to warm up. Put less strain on your vehicle by avoiding high speeds and accelerating quickly, especially in very hot or cold conditions. 

Avoid those short tips throughout the day by consolidating your drive. Most of the wear and tear takes place in the first few minutes of driving. It also adds more pollution to the air. If you can consolidate them, doing several errands at once, it helps you become a better driver. And helps your car out too. 

Care For Your Tires

Tires are one of the most vulnerable parts on your vehicle. Why? Because they are in constant connection with the road. Hit a pothole, and it can impact many parts throughout your car. Curbing the tires can impact your tires, wheels, and drivetrain. The wrong air pressure can put your safety at risk. 

With that much riding on your tires, isn’t it a wonder in all they can do?

It should also motivate you to want to keep them in the best possible condition. Most experts agree that checking your tire pressure a couple times a month is best to prevent damage. Soft tires can quickly overheat, or even blow out when you’re out on the road. 

If your dashboard alerts you to varying tire pressure, take notice. Even slight variations can have a noticeable effect on your drive. If there’s a problem, get it checked out. 

How Do You Extend The Lifespan of Your Vehicle? 

Extending the lifespan of your vehicle isn’t a cut-and-dry procedure. There are guidelines you can follow, as well as go with your gut feelings.

Refrigerant – It’s What Keeps Your Car’s AC Running Efficiently

June 18, 2024 by Denver Express Car Care

On a 90-degree day, nothing feels better when you get into your car than a cool breeze flowing through the vents. It can help a little of your stress disappear as you feel the temperature fall. 

Yet sometimes it might feel as if it takes longer for that to occur. You keep it on full blast, wondering where the cool air is. 

Then there are efficiency issues – does AC operation mean less fuel efficiency? What if you want both? 

No matter what you’ve heard about keeping your car’s AC running efficiently, we bet there are a few myths you may still believe. Let’s get to the nitty-gritty of a car’s AC system and find out how to stay cool all season long. 

How a Car’s AC System Works

It’s actually a fairly simple process. 

A car’s air conditioning system works by removing heat from inside the car and expelling it outside, making the air inside cooler. It uses a special substance called refrigerant that circulates through the system. The process starts with the compressor, which is powered by the car’s engine. The compressor squeezes the refrigerant gas, increasing its pressure and temperature.

Next, the hot, high-pressure refrigerant gas moves to the condenser, which is located at the front of the car near the radiator. As air flows over the condenser, the refrigerant releases its heat and changes into a high-pressure liquid. This cooled liquid then travels to an expansion valve, where it quickly expands. This expansion lowers its pressure and temperature, turning it into a cold, low-pressure liquid.

Refrigerant - It’s What Keeps Your Car's AC Running Efficiently

The cold liquid refrigerant then goes to the evaporator, which is inside the car’s dashboard. The car’s blower fan pushes warm air from the interior over the evaporator coils. The refrigerant absorbs the heat from the air, causing it to evaporate into a gas. This process cools the air, which is then blown through the car’s vents, making the interior cool and comfortable.

The refrigerant, now warm and low-pressure again, goes back to the compressor, and the cycle starts over. This continuous loop removes heat from the car’s interior and expels it outside, keeping the car cool. Additionally, as the evaporator cools the air, it also removes moisture, dehumidifying the car’s interior. The condensed water from this process drains outside the vehicle.

Let’s Talk Refrigerant – An Essential Part of an AC System

As you’re reading above, you’ll notice refrigerant stands out as an essential part of the cooling process. That makes it one of the important fluids you should inspect regularly throughout the cooling system, as it’s crucial for your car’s AC system, helping cool and dehumidify the air inside your vehicle. Here’s what you need to know about refrigerant:

How to Know if Your Car Has Proper Refrigerant

First, check if your car’s AC system is blowing cold air when set to maximum cooling. If it is, you likely have enough refrigerant. Pay attention to how quickly your car cools down; if it takes longer or the air isn’t as cold as it used to be, the refrigerant level might be low. Some cars have a sight glass on the refrigerant lines where you can see the refrigerant flow; bubbles in the sight glass can indicate low levels. During routine maintenance, a mechanic can use gauges to check the refrigerant pressure. Proper pressure readings indicate the right amount of refrigerant.

How Often Should Refrigerant Be Checked?

It’s a good practice to have your car’s AC system checked at least once a year, ideally before the hot summer months. This ensures the system is in good working order and can help detect any issues early. If you notice any decline in AC performance, unusual noises, or if the air isn’t as cold as it should be, have the refrigerant levels checked immediately.

What Happens if Refrigerant is Low?

Low refrigerant levels mean the AC system cannot cool the air effectively. You’ll notice that the air from the vents is not as cold as it should be. The AC compressor relies on refrigerant for lubrication and cooling. Running the system with low refrigerant can cause the compressor to overheat and fail, leading to expensive repairs. The evaporator removes moisture from the air, but low refrigerant levels reduce its efficiency, leading to higher humidity inside the car. Additionally, low refrigerant often indicates a leak in the system. Refrigerant leaks can be harmful to the environment and need to be addressed promptly by a professional.

Tips for Maintaining Proper Refrigerant Levels

Include AC system checks in your regular vehicle maintenance schedule. Have a certified technician inspect your AC system annually, especially before summer. If you suspect a refrigerant leak or experience reduced cooling, seek professional help immediately to prevent further damage and ensure optimal performance.

AC’s Effect On Fuel Efficiency

According to the US Department of Energy, running your car’s AC system is the main contributor to reduced fuel economy in hot weather. Of course, there are a number of factors that impact that reduction: outside temperature, humidity, intensity of the sun, to name a few. But in very hot conditions, AC use can reduce a conventional vehicle’s fuel economy by more than 25 percent. EVs and hybrids can be even more. 

The refrigerant in your car’s AC system indirectly affects fuel efficiency through its role in the AC compressor’s operation. When you turn on the AC, the compressor pressurizes the refrigerant and circulates it to cool the air. This process requires additional engine power, increasing fuel consumption. The harder the compressor works, the more fuel the engine uses.

Having the right amount of refrigerant is crucial for efficient AC operation. When refrigerant levels are optimal, the AC system works efficiently, cooling the air with minimal strain on the compressor. This results in a moderate increase in fuel consumption when the AC is on.

If the refrigerant levels are low, the compressor has to work harder to cool the air, leading to higher fuel consumption. The engine must produce more power to drive the overworking compressor, using more fuel in the process. Too much refrigerant (an overcharged system) can also cause problems. Excess refrigerant increases pressure and strain on the compressor, making the system less efficient and consuming more fuel.

What’s the answer? How do you ensure efficiency throughout the season? 

It starts with regular maintenance. 

Regular maintenance of the AC system, including checking and refilling refrigerant levels, ensures it operates efficiently. An efficient AC system requires less power from the engine, helping maintain better fuel economy. A well-maintained compressor that runs smoothly and efficiently uses less energy, conserving fuel. Additionally, ensuring there are no leaks or blockages in the AC system helps maintain proper refrigerant levels and optimal compressor performance, both crucial for fuel efficiency.

We also suggest protecting your vehicle no matter where you are. Park in shaded areas or use sunshades to protect your interior. 

Open the windows when you first get into your car on a hot day. Let the open windows air out some of the hot air while you start your vehicle, then allow the AC to gradually cool the interior down. This puts less demand on the AC and helps cool your car faster. 

Staying Cool All Summer Long

Efficiency starts by understanding your vehicle a little better. Want a cooler, more comfortable drive? It starts with creating a well-maintained vehicle, one that drives well in any road condition.

The Impact of Weather on Your Car’s Performance

June 14, 2024 by Denver Express Car Care

Heading to work this morning? Need to run an errand? We think very little about our car’s performance when we slip behind the wheel. We turn the key, and expect it to go. 

But what if it doesn’t? What if you hear a noise? Or feel a vibration? Or smell something that definitely isn’t normal. Then what?

You might jump to thoughts about your drive in the past few days. Did you knock something loose when you hit the pothole? 

You might also ask yourself: Could it be the weather? 

Weather can have a big impact on your car’s performance. And weather is something that changes frequently across the Front Range. Cold one minute, sizzling hot the next. 

Did you know summer and winter can both take its toll? 

How Summer Impacts Your Car’s Performance

You’re driving along, air conditioner full blast. Except it doesn’t seem to be working. You roll down the windows – anything to escape this intense heat. You chug water, trying to stay cool. Only a few more hours and the sun will fade. 

You know what it feels like on the hottest days of the year. Now imagine what your car must be going through. 

The engine is at risk of overheating. The intense heat can cause your engine to overheat if your cooling system is malfunctioning. 

The Impact of Weather on Your Car's Performance

Tire pressure fluctuates as it connects with scorching pavement. Warm weather causes tire pressure to increase, potentially leading to overinflation and increased risk of a blowout. 

The battery might fail. High temperatures can cause battery fluid to evaporate, damaging the internal structure and reducing battery life. 

And your brakes – what if they fail? Higher temperatures can cause brake fluid to boil, leading to brake fade and reduced braking efficiency. 

Maybe you’ve noticed it as you pull in for fuel more frequently. On hot days, you use more air conditioning, which can lower fuel efficiency as the engine works harder to power the AC system. That extra work can also impact the cooling system as it works harder to keep the inside of your car cool.

Heat makes every fluid in your car evaporate a little quicker at high temperatures. That includes motor oil, transmission fluid, coolant, and brake fluid. 

Sun beating down can take its toll on the exterior and interior. Prolonged exposure to the sun can damage paint and interior materials. 

Tips for Maintaining Your Car in Summer

Why fix what’s not broken? That’s the way many drivers look at car maintenance. Yet we think there’s a better way. 

See, when you take a proactive approach, you’re conditioning the various systems in your car to be in tip-top shape. You catch potential problems long before they have a chance to materialize. Which means you won’t face the consequences on the road, when you least expect it. 

What we suggest for summer car maintenance is pretty easy:

  • Schedule regular check-ups to ensure all systems are functioning correctly.
  • Keep an eye on all fluid levels and top them up as needed.
  • Monitor tire pressure and inspect for signs of wear and tear.
  • Ensure the cooling system is in top condition to prevent overheating.
  • Test your battery and clean any corrosion to maintain optimal performance.
  • Use sunshades and protective coatings to safeguard your car’s exterior and interior.

Easy peasy. And this stuff really makes a difference. You can skip worrying about your car all summer long. Until winter hits …

How Winter Impacts Your Car’s Performance

You’re at work, dreading the drive home. The temperatures have dropped. Snow is creating whiteout conditions. Ice is piled everywhere. 

Did we mention cold? You know it’s cold when there’s a negative on the thermometer. Maybe getting home won’t be the problem. Maybe getting the car started will be the issue. There is a lot that can impact your car’s performance. 

Battery life is always impacted on those bitter cold days. Low temperatures reduce battery capacity, making it harder for the engine to start. 

Cold weather can cause your tires to lose traction, especially on icy or snowy roads. 

Ever feel like you slow down, cuddled in your jackets, trying to keep the blood flowing? As the temperatures drop, your car goes through a similar experience. Cold temperatures can cause engine oil and other fluids to thicken, reducing engine efficiency. 

When you’re ready to head out, you let your car idle for a bit, just to warm up. That extra idle time lowers efficiency and consumes more fuel. 

And though it may sound counterintuitive, coolant can freeze, which in turn can cause engine block damage. You need a coolant mixture that has the right amount of antifreeze to prevent it from freezing up, summer and winter. 

You may feel like you slip and slide more, but it’s not just the tires. Brake performance can also be impacted, making them less responsive. A quick check can tell if your brake fluid levels are topped off and brake pads are in good working condition. 

A malfunctioning heating system can make the drive uncomfortable and unsafe. Regular checks ensure the heater core is in good working condition. 

Tips for Maintaining Your Car in Winter

You’ve had your car inspected in the spring, ready for summer. Why look at it in the fall, getting ready for winter? Think back to all the places you’ve driven, all the rough roads you’ve traveled over, and the adventures you’ve had. Every mile can impact your vehicle. That’s why it’s time once again to schedule a maintenance visit. 

  • Schedule regular check-ups to ensure all systems are functioning correctly.
  • Switch to winter tires for better traction and control.
  • Keep an eye on all fluid levels and top them up as needed.
  • Test your battery and consider using a battery warmer.
  • Ensure the coolant mixture is suitable for low temperatures.
  • Use winter wiper blades and keep washer fluid topped up.
  • Carry de-icing tools and use proper defrosting techniques.
  • Wash your car regularly to remove salt and apply rust protection.

Imagine, two maintenance visits a year to keep your car in good operating condition. Two maintenance visits a year to ensure your car is running well. 

It doesn’t take much. But it can make a world of difference. In the way your car handles. In the amount of money you spend on repairs. In the way your car operates out on the road. In the peace of mind it brings you. 

When was your last maintenance inspection?

The Importance of Transmission Service: What You Need to Know

June 7, 2024 by Denver Express Car Care

Some car maintenance words are so … challenging. You hear them. You play along – of course, you know what they mean. Who doesn’t know what a differential is? Or a serpentine belt, a tie rod, or a caliper. A transmission? Well …

We get it. Not everyone is meant to be a mechanic. You have a lot going on in your life. You’re running around from morning til night. You don’t need to know the inner workings of a transmission. But what you do need to know is the importance of transmission service. 

A Car Transmission – The Basics

When you hear the term transmission, think about wheels. A transmission is a mechanical component that is responsible for transmitting power from the engine down to the wheels. It gives you the ability to control the car’s speed and torque by shifting gears. This allows the engine to operate efficiently across various speeds and driving conditions. 

This is what allows you to accelerate, decelerate, and maintain speed. 

You may be driving an automatic transmission now, but there are several other types. A manual transmission allows you to manually shift gears using a clutch pedal and a gear stick. A continuously variable transmission provides seamless acceleration without distinct gear shifts by using a system of pulleys and belts. A dual-clutch transmission uses two separate clutches for odd and even gear sets, creating faster and smoother gear shifts. 

If your brain is already moving to “too much information,” we get it. We’re not going to give you the advanced version of how a transmission works. Suffice it to say that all you need to know is that your car won’t go if the transmission isn’t operating well. That’s why transmission service is so important. 

The Importance of Transmission Service: What You Need to Know

Is It Time To Schedule Transmission Service? 

If you’ve been driving for any length of time, you know cars need regular service to keep operating. With thousands of parts, each system is set up on its own schedule. The best way to learn about each system is to check with your owner’s manual. Of course, getting to know a local mechanic can help too. They can keep you updated on how well your car is operating, and what you can expect in the future. 

Transmissions aren’t like oil changes – they don’t need servicing every few thousand miles. That said, most makes and models do suggest transmissions are serviced every 30,000 to 60,000 miles or so, just to ensure they’re working well. 

This is where a mechanic will change transmission fluid and filter, inspect the transmission pan, and check for leaks and other issues. They’ll look for any signs or wear or damage, and evaluate it for proper operation. 

The 30,000 to 60,000 rule is just a suggestion. Think about the way you drive. If you frequently drive under severe conditions – towing, driving in heavy traffic, or in extreme temperatures – you might need to bring your car in more frequently. 

What a Mechanic Will Do During a Transmission Service

You bring your vehicle in for a transmission service. A mechanic will start with a transmission fluid change. 

This means the mechanic will drain the old transmission fluid and refill it with new fluid. This helps to remove contaminants and ensure the transmission operates smoothly. 

Transmission fluid is essential for a variety of reasons. 

  • It lubricates the moving parts inside the transmission, reducing friction and preventing wear and tear. 
  • It helps dissipate heat generated by the transmission during operation, preventing overheating, which can cause damage.
  • In automatic transmissions, the fluid acts as a hydraulic fluid, enabling the transmission to shift gears smoothly.
  • It contains detergents and additives that help clean and protect the internal components from corrosion and buildup of debris.
  • It ensures the transmission operates efficiently, providing smoother gear shifts and better overall performance.
  • It prevents damage. Old, degraded fluid can lead to overheating, slipping, or harsh shifting, which can cause significant damage to the transmission components.

That’s a lot of reasons to upgrade your transmission fluid, right? If for no other reason than to give your car new transmission fluid – that should be reason enough to bring it in for regular servicing. Of course, a mechanic does more than that. 

They’ll replace the transmission filter, which helps keep the fluid clean by trapping debris and particles. They’ll remove the transmission pan, clean it, and inspect it for any metal shavings or debris that can indicate wear or damage. They’ll check for fluid leaks. They’ll inspect and adjust bands and clutches and clutches and gears, just to ensure everything is working the way it should. 

And that’s all that really matters. When you drive away, you want the peace of mind that comes with knowing your car is in good shape and won’t need servicing again for a long while. 

You’re good to go, and your passengers will be safe and secure as you go about your busy days. 

Your Transmission Is Saying: It’s Time For Servicing

The easiest way is by watching your mileage – if it’s been 30,000 to 60,000 miles since your last transmission service, it may be time. Of course, vehicles are built to alert you when things are starting to go wrong. 

That trusty check engine light on your dashboard is a catch-all for all sorts of vehicle issues. When that pops on, schedule a visit. It helps keep your car in tip-top shape, fixing minor issues before they grow more significant. 

Pay attention to strange noises, like whining, humming, clunking, especially when shifting gears. Or if you notice anything funny with the way the car shifts – it might slip out of gear while driving, or delay when shifting from park to drive. These are all signs the transmission needs attention. 

See a leak on your driveway where you normally park your car? If it’s a reddish color, it can indicate a transmission fluid leak. You can also pop the hood to see if you notice leaks. If you regularly check the transmission fluid’s color and consistency, it should be a clear reddish color. If it’s dark, dirty, or has a burnt smell, it’s time for a change. 

Bottom line: if something “feels” off, it’s best to bring it in. 

You know your car. You know if something doesn’t feel right. And if you notice any of the signs above, it might be your transmission. Bring it in, we’ll fix it, and have you on the road again. 

Isn’t that what’s most important?

When Things Heat Up, It Might Be Time For Car AC Repair

May 24, 2024 by Denver Express Car Care

What does summertime in Colorado mean to you?

  • As much time outside playing with your friends. 
  • A drive into the mountains – it’s beautiful, with so much to do.
  • Taking the kids on small road trips to see more of this amazing state.

Whether you said yes to one of those, or you have a list all your own, chances are you’ll spend a lot of time behind the wheel. Have you seen the roads these days? It’s endless traffic. Will you spend the time with your windows rolled down because the AC doesn’t work?

Maybe it’s time for car AC repair. 

Your Car AC System

Your car’s AC works similarly to your home’s AC. At the heart of the unit is refrigerant. It’s a special fluid with a low boiling point. It moves into a compressor, which increases its pressure and temperature, turning it into a gas instead of a liquid. 

It then moves to a condenser that dissipates the heat from the refrigerant, causing it to condense into a high-pressure liquid. It flows through an expansion valve where it regulates the flow of the refrigerant, reducing the pressure, causing it to expand rapidly. This leads to a drop in temperature. 

The now-cool refrigerant flows into the evaporator, located in the car’s dashboard. Air from outside the car is drawn in and blown over the evaporator coils, cooling the air. As it moves over the cold coils, moisture condenses, dehumidifying the air.  

When Things Heat Up, It Might Be Time For Car AC Repair

The blower fan then pushes the cooled and dehumidified air into the passenger cabin, lowering the temperature to your desired level. Using the thermostat and controls gives you a chance to adjust the desired temperature and fan speed, regulating the overall operation. 

It may seem like a fairly simple operation, but a number of things can go wrong. 

What’s Wrong if Your Car AC is Blowing Hot Air?

Now that you know how a car AC works, it’s easier to understand what can go wrong. 

It Might Be a Refrigerant Leak

One of the most common reasons for blowing hot air comes from a refrigerant leak. If there isn’t enough refrigerant inside the system to circulate properly, it won’t be able to cool your passenger compartment. Refrigerant isn’t colored like other fluids inside your car. It typically appears as a clear, oily liquid, though it can pick up dirt and debris, darkening the appearance. It often appears as a faint rainbow sheen if it hits the pavement. 

It Might Be Compressor Issues

The compressor is responsible for pressurizing the refrigerant. If it isn’t working correctly or engaging, the AC won’t cool the air. This could be from a variety of issues, including electrical issues, a faulty clutch, or other compressor-related problems. 

It Might Be a Condenser or Evaporator Problem

The condenser or evaporator can leak or clog over time, which will also lead to warm air blowing through the AC vents. This can be from age or wear and tear over time. 

It Might Be Clogged or Blocked Air Filters

Air from outside moves into the system before it’s cooled and blown into the passenger compartment. It moves through a filter, which can clog over time. In some cases, fixing your AC system could be as simple as cleaning or replacing an air filter. On many vehicles, this filter can be found at the base of the windshield, making it easy to find. You can use a vacuum to suck out dirt and debris. If that doesn’t fix the problem, it could be a deeper problem. 

It Might Be Electrical or Sensor Issues

Today’s modern cars are heavily controlled by electrical components and sensors. If a problem starts in any one of these areas, it can also cause the AC system to malfunction. Issues with temperature sensors or the control panel may prevent the system from regulating the temperature. 

It Might Be The Cooling Fans

The cooling fans in front of the condenser help dissipate heat from the refrigerant. If these fans aren’t working correctly, the AC may struggle to produce cool air. You’ll often notice this more when your car is idling, or you’re driving around the neighborhood at low speeds. 

How To Properly Maintain Your Car’s AC

The good news is a car’s AC system is easy to maintain. 

Every year, you schedule a checkup with your doctor just to check in. They might request bloodwork, take a few measurements, or schedule a few tests to ensure you’re in good health. 

Taking the same approach with your vehicle can ensure it stays operational all year, no matter where the drive takes you. Schedule a maintenance visit before summer heat kicks in, and a mechanic will inspect your AC systems for signs of leaks, wear and tear, or any damage that may have occurred. If you notice unusual noises or strange odors, have them addressed promptly by a technician. 

We’ve mentioned it before, but it’s worth mentioning again. Replacing the cabin air filter ensures proper airflow and helps maintain air quality inside the car. Check your owner’s manual for manufacturer recommendations, or replace it more frequently if you drive in dusty environments. 

You should also check refrigerant levels from time to time. If you notice a decrease in cooling performance, have the refrigerant levels checked by a professional. Low refrigerant levels can indicate a leak or other issues within the system. 

It’s also important for a technician to occasionally inspect the belts and hoses connected to the AC compressor for signs of cracks, wear, or leaks. Age impacts a lot of things under the hood – don’t wait until they’re damaged. It’s easier on the pocketbook and your peace of mind if you replace it before it gives you trouble. 

Schedule Car AC Repair Before the Heat of the Summer

As the temperatures rise during the summer months, your car’s air conditioning becomes an essential component for comfort and safety. To ensure your AC system is ready to tackle the heat, schedule any necessary repairs or maintenance before the peak of summer arrives.

By proactively addressing any issues with your car’s AC system, you can avoid the inconvenience of being without cool air when you need it most. Whether it’s addressing refrigerant leaks or simply performing routine maintenance, taking care of your AC system before the summer heat sets in can help prevent breakdowns and ensure optimal performance.

Don’t wait until the sweltering heat of summer is upon you. Take proactive steps to schedule any necessary repairs or maintenance for your car’s AC system now, so you can stay cool and comfortable on the road when the temperatures soar.

Buying Used? Car Inspection Service Is What You Need

May 18, 2024 by Denver Express Car Care

They say new car prices are falling in 2024, but with the average price still hovering near $49,000, that can impact your new car purchasing plans. 

Used cars aren’t faring much better. Fewer leases occurred during the pandemic, which means fewer certified pre-owned vehicles are making their way to the used car marketplace. With fewer cars available, this means premium pricing for the used cars that remain. 

If you’re in the used car market, how do you know if you are about to purchase a good vehicle? What can you do to put the odds in your favor? Used car inspection service may be just what you need. 

Used Car Inspection – Self Service

When you’re looking at a used car, there are some things you can evaluate on your own. 

Take a walk around the vehicle to look at the exterior and body. Check for dents, scratches, rust spots, and panel alignment to ensure there hasn’t been any unreported damage. This may be easy to spot, and you might be okay with the damage that’s there. But it is important to know what you’re walking into before you sign on the dotted line. 

Examine all glass and mirrors for cracks and large chips. This can obstruct your vision and be a safety hazard. Ensure lights and lenses are all intact and functioning properly so you can drive safely at night. 

Buying Used? Car Inspection Service Is What You Need

With the outside inspected, it’s time to open the door and climb inside. Check the upholstery for tears, stains, and general wear in the seating and carpet. 

Evaluate the controls and the dashboard panel. Confirm that all gauges, lights, and indicators work, including the HVAC system, stereo, and navigation. 

Test all power windows, locks, and sunroof to ensure they operate smoothly and without issue. 

Take the time necessary for a full inspection before you go for a test drive. Being on the road can alert you to any noises, smells, feelings you get as you navigate through the community. Take note of any issues for further inspection.

Used Car Inspection – Find a Trusted Repair Service

If a vehicle passes your self-inspection test, it’s time to bring your vehicle in to have a professional check it out. 

It’s one of the reasons we like to partner with drivers when it comes to taking care of their cars. If you get to know us as you care for your vehicle, you’ll have someone to trust when it comes time for purchasing something new. We’ll have an established relationship to help you through this major purchase. You’ll feel better as you drive away with a new-to-you car. 

We’ll also give it the once-over to examine the body and exterior, as well as the interior and comfort. You might have already noticed a few of these items, but we’re happy to give you our opinion on how they will fare in the future. 

From there, we head under the hood. Diagnostics is a friend; it will alert you to any potential problems. It can find things we aren’t capable of seeing with our eyes. Instead, it looks through a mechanical and electronic lens, and pulls anything that may differ from what the guidelines expect. 

Of course, that doesn’t mean a trained and experienced mechanic can’t fully inspect a car and give you an opinion. We can do a lot of things to determine its condition. Like checking fluid levels and the condition of the oil, coolant, brake fluid, and transmission fluid. We can inspect belts and hoses for wear and leaks. We can assess the battery’s age and health, and check the wiring or for any obvious issues. 

From there, we head under the car. We check the condition of the shocks, struts, and brake pads and look for signs of uneven wear. Because a car with a faulty suspension or brake system is clearly one you may want to reconsider. 

Here in Colorado, we have stringent exhaust regulations in place. We’ll check out the exhaust system, looking for rust, holes, or illegal modifications. If it can’t pass an emissions test when you buy it, it’s only looking for trouble down the road as you continue to face issues. 

Then we’ll evaluate the drivetrain, examine the transmission, differential and axles for leaks and wear. We understand here in Denver you might drive as much in the city as you take in road trips deep into the mountains. We’ll make sure your car is ready wherever the road takes you. 

It’s time to check the tires. We’ll evaluate tread depth and wear patterns, which can indicate issues with alignment or suspension. We’ll check the wheel alignment and confirm that the car drives straight without pulling to the left or right. Then we’ll take the car out for a road test to see how it performs. There’s a lot a mechanic can tell simply by driving it around – we’ll ensure everything runs smoothly without hesitations, noises, or anything else that seems ineffective. 

One Final Test – Many Drivers Forget This

You’re looking at buying a new-to-you car. You’re excited about the make and model. You like the looks and are happy with its condition. But there’s still one more check you should make, and that includes a history and documentation check. 

Depending on who owned the vehicle, you may be able to get a service history to review. This can alert you to past servicing and give you a better idea of the maintenance routine. 

A trusted mechanic will alert you to any recall information, to ensure there are problems that need to be fixed, or recalls that have already been addressed. 

If you’re purchasing from a private party, do a title and ownership check too. This will ensure the vehicle’s documentation is legitimate and there are no liens against the car. 

Congratulations!

With all of these checks and inspections in place, you can purchase the used car with more confidence and good faith. 

Then as you drive away and back into your daily routine, remember, regular maintenance is what ensures a long life. Check your owner’s manual, set up a schedule, and bring your car back in for regular routine maintenance. 

We’ll help ensure your used car has a long life.

Car Exhaust System Acting Up? Repair It Now

May 14, 2024 by Denver Express Car Care

If you’ve been driving for a while, you probably recognize the signs of brake trouble. Nothing sounds like screeching metal-on-metal when brake pad material is wearing down. 

You know to replace the oil periodically, and to buy new tires when the tread is fading. 

But what about a car exhaust system? When is it in need of repair? How do you know? 

Like any system on your vehicle, there are warning signs. Paying attention on your daily drive can alert you to potential problems. And provide warning signs to fix your vehicle quickly to avoid bigger issues down the road. 

The Purpose of a Car Exhaust System

In simple terms, a car exhaust system has one purpose: to remove harmful substances and gasses away from the vehicle. In truth, it’s a bit more in-depth. 

The exhaust system’s primary purpose is to reduce harmful emissions from the engine. Components like the catalytic converter help turn hazardous gasses such as carbon monoxide, nitrogen oxides, and hydrocarbons into less harmful substances like carbon dioxide, nitrogen, and water vapor before they are released into the environment. But that’s not all it does. 

Car Exhaust System Acting Up? Repair It Now

The exhaust system helps to efficiently expel combustion gasses from the engine, which is crucial for maintaining proper back pressure in the engine. Optimal back pressure ensures that the engine runs efficiently, maximizing power while minimizing fuel consumption. You wouldn’t have an efficient, well-performing engine without the exhaust system. 

Have you ever listened to a car where they’ve stripped away parts of the exhaust system? The exhaust system, particularly the muffler, plays a crucial role in dampening the sound made by the escaping exhaust gasses. This noise reduction is essential for meeting regulatory standards and for maintaining a quieter operation of the vehicle. 

It’s not just a noise reducer; it’s about safety too. The exhaust system directs exhaust away from the vehicle, keeping harmful pollutants away from the engine and the vehicle’s cabin. That creates a safer environment for the car’s occupants and reduces potential heat damage inside the engine compartment. 

It’s Not Just Creating a Safer Vehicle; It’s Regulated Too

The exhaust system may be a part of your vehicle, but it does just as much for the environment as it does for your car. Cars are subject to stringent regulations designed to protect the environment and public health. Governments around the world have established specific standards that dictate how much pollution a vehicle can emit.

Here in the United States, the Environmental Protection Agency (EPA) sets emissions standards for cars and trucks. These regulations focus on limiting the release of harmful pollutants such as nitrogen oxides (NOx), carbon monoxide (CO), hydrocarbons (HC), and particulate matter (PM) into the atmosphere. Vehicles are required to pass emissions testing to ensure they meet these standards before they can be sold or operated on roads.

Colorado has its own set of rules. Years ago, a brown cloud hovered across the Front Range. Today, it’s been replaced by a thick smog. When you hear we’re having a poor air quality day, it’s often due to an overabundance of smog in our atmosphere. 

The Colorado program was set up to monitor gas emissions and keep the worst polluters off the roads. Different counties throughout Denver require an emissions test to register a vehicle. You’ll have to visit a Colorado Air Care Testing Facility according to guidelines to ensure your vehicle fits within the limits. 

How Do You Know If Your Exhaust System Is Acting Up?

Like other systems, a car’s exhaust system won’t fail without warning. It will alert you to potential problems; it’s up to you to recognize the warning signs. 

  • Loud Noises: If you start hearing unusual noises like rumbling or roaring from your exhaust, it could indicate a hole or a disconnected part in the exhaust system, particularly in the muffler.
  • Decreased Fuel Efficiency: If your car starts consuming more fuel than usual, it could be a sign that the exhaust system is not functioning properly. A damaged exhaust system can cause the engine to work harder, which in turn increases fuel consumption.
  • Bad Odors: A well-functioning exhaust system will direct exhaust fumes away from the vehicle to keep them from entering the cabin. If you notice an unusual smell, particularly the smell of rotten eggs (which could be due to a failing catalytic converter), it’s a clear sign something might be wrong.
  • Visible Smoke: Excessive smoke from the exhaust pipe can be a symptom of problems within the exhaust system. Different smoke colors can indicate different issues. For example, blue smoke might suggest oil burning in the engine, while white smoke often indicates a coolant leak. This can happen due to a cracked or warped engine block, a head gasket failure, or a crack in the cylinder head.
  • Check Engine Light: The check engine light can come on for numerous reasons, and one potential reason is an issue with the exhaust system, including the catalytic converter or oxygen sensors.
  • Reduced Power and Acceleration: If your vehicle feels sluggish and lacks power during acceleration, it could be due to an exhaust system problem affecting the engine’s ability to breathe properly.

Car Exhaust System Repair

Maintaining the exhaust system is key to ensuring it runs smoothly, efficiently, and safely. Regular inspections and timely repairs can help prevent larger, more expensive issues down the road and ensure that your vehicle meets emission standards.

It’s a good practice to have your exhaust system checked at least once a year. A mechanic can look for physical damages, leaks, rust, and other wear-and-tear that might affect its performance.

If you notice any of the warning signs of exhaust problems, get your vehicle inspected immediately. Delaying repairs can lead to more significant damage and potentially more costly fixes.

When repairs are needed, using high-quality replacement parts is crucial. This ensures that your exhaust system functions properly and lasts longer without recurring issues.

Due to the complexity and importance of the exhaust system, repairs should generally be handled by professional mechanics. They have the expertise and equipment to diagnose issues accurately and make repairs that comply with safety and environmental regulations.

Decoding Common Signs of Transmission Problems Before They Escalate

May 3, 2024 by Denver Express Car Care

When you get into your car, you expect it to go. You’ve got a busy day ahead, with lots to think about on your drive into work. 

But what if your car doesn’t go? 

Picture this: You cruise onto the highway, and your engine starts racing. You can hear the transmission isn’t shifting gears. It whines and grinds, but no movement. You know something is wrong. You pull over to the side of the road … it’s going to be a long day. 

Transmission problems can be the most stressful, expensive repair issues to deal with. 

But the good news is you don’t have to wait for transmission problems to escalate before you take action. Warning signs start to appear long before problems occur. Let’s cover a few of them so you can start taking action now. 

Ignoring Maintenance

One of the most common reasons transmissions fail for all vehicles is not following manufacturers’ maintenance recommendations when caring for the engine and transmission. They push the mileage when scheduling fluid and filter changes. They push off maintenance until they “have more time.” 

Here in Colorado, that can be dangerous, especially if you enjoy our outdoor lifestyle. You frequently head up into the hills for skiing, hiking, and biking. You tow campers and boats for a weekend of play. These harsh conditions are taking a toll on your vehicle’s inner-workings. Without proper fluid levels, it no longer lubricates properly. Without clean filters, your vehicle won’t cool properly, leading to overheating, failure, and a host of other mechanical issues.  

Decoding Common Signs of Transmission Problems Before They Escalate

Fluid Leaks

The second most common way your transmission will warn you of pending issues is through a transmission leak. Transmission fluid leaks can occur at various points in the transmission system, including seals, gaskets, or cooler lines. Leaks lead to low fluid, burnt fluid, overheating, and eventual damage that will no longer be repairable by just adding fluid. 

A transmission fluid leak is usually red, ranging from light pink to a brownish color, depending on its age. If you notice this color leaking from your car and pooling underneath the front of your car, it’s likely a transmission leak. Identifying the source of the leak and repairing it promptly is crucial to maintaining proper transmission function and preventing fluid loss, which can lead to overheating and damage. If it isn’t caught early, it can lead to needing a replacement or rebuilt transmission. 

Strange Noises

Vehicle noises differ depending on where the problem lies. But if you hear anything out of the ordinary, pay attention. Can you describe it as humming, buzzing, whining, or clunking? Those are the most common ways people describe transmission problems. With hundreds of parts inside the transmission system, even one loose bearing can throw the entire system off. Each sound signals a different potential issue:

  • Grinding noises typically occur when there’s a problem with the gears, such as worn synchros or teeth. These sounds often indicate that the transmission is having difficulty synchronizing the gears, which can lead to further damage if not addressed.
  • Whining or humming noises might indicate low transmission fluid or a worn-out bearing. Both scenarios can lead to serious transmission issues if left unattended.
  • Clunking sounds when shifting gears could be a sign of worn-out or damaged transmission mounts, which can cause the transmission to shift unexpectedly and result in further damage to surrounding components.

Only  a thorough inspection of the system can isolate where the noise is coming from and point to where the problem originates. Trust your mechanic to get to the root of the problem. 

Warning Lights

Thank goodness for modern cars. Their technological advancements have done wonders helping you solve issues before they escalate and turn into bigger problems. Depending on your make and model, you may have 20 to 30 dashboard lights ready and waiting to alert you to potential problems. Don’t ignore them – they light up for a reason. 

Dashboard warning lights such as the Check Engine Light or Transmission Temperature Light are designed to alert you to potential issues with the transmission system. The Check Engine Light is one of the most common lights to illuminate; it can signal many different issues in your car. Bringing your car in early for an inspection means we’ll catch the problem before it escalates, potentially saving you money on more severe problems. 

Slipping Gears

Do you hear the engine revving higher than it should when driving down the road? Does it lack power or sound like it’s slipping gears? People often describe this in many ways, yet you’ll know when it feels like your car is clunking as you speed up and slow down. 

Transmission slipping occurs when the transmission fails to maintain a consistent gear, resulting in the engine revving higher than usual without a corresponding increase in vehicle speed. This can be caused by many things, including worn-out clutch bands, clutch packs, or torque converters. You can prevent slipping transmission by maintaining your fluid levels and ensuring you don’t have any leaks. When you find a problem, get it fixed immediately. 

Burning Smell

A burning smell is never a good sign. In most cases, a burning smell comes from overheated transmission fluid, or leaking fluid. Low fluid levels cause excessive friction which exacerbates the situation. Ignoring this smell could lead to severe transmission damage or failure.

Solenoid Issues

Solenoids in cars perform many different functions, from helping start the engine to assisting in shifting gears. They control upshifting and downshifting while you drive. If solenoids are damaged or wear down, it can damage your transmission, cause shifting problems, leading to diagnostic codes showing up in your vehicle’s computer. 

A car’s computer sends 100s, if not 1000s, of signals to the solenoids a second, telling your vehicle how much pressure it needs, when to shift, how fast to shift. This level of action eventually wears parts down, causing you to notice it in the way your car shifts and moves. It may be as simple as replacing the solenoid if it has become defective. 

Do you Have Transmission Problems? 

From the moment you notice a first sign of a problem, your best course of action is to schedule an inspection. It’s the easiest way to stop issues early before they rise in significance and escalate to a more costly problem. 

Have a transmission issue? Let’s chat. Give us a call, and we can schedule a time to inspect your car, find the issue, and make the repair. It’s the best way to get you on the road again. It’s the best way to bring peace of mind to your drive.
