Understanding the Role of Engine Diagnostics in Car Repair

July 7, 2023 by Denver Express Car Care

Imagine your world if there were no computers. 

You wouldn’t hold a smartphone in your hand, or use your tablet to watch your favorite podcast. You wouldn’t use your phone to adjust the furnace up a few degrees when you’re coming home from work. 

There would be no internet. You wouldn’t pay your bills at the touch of a button. Life would be simpler … and more complicated. 

Now think about your car. Since the mid-1990s, every gasoline car engine produced has come equipped with an onboard computer system capable of being accessed by diagnostics. When you take your vehicle into a repair shop, the mechanic will almost always plug a diagnostic tool into a port under the dashboard, and use the information collected to narrow down the problem. 

It can alert them to potential issues before they become bigger problems. It allows you to make minor repairs before they escalate into full-blown overhauls. 

What is a diagnostic test?

Have you ever wondered how mechanics pinpoint and fix issues with your car’s engine? The answer lies in the crucial role of engine diagnostics. In today’s modern vehicles, sophisticated computer systems continuously monitor various aspects of the engine’s performance. Through diagnostic tests, mechanics can effectively identify problems and provide accurate solutions.

A diagnostic test is a check-up for your car, performed using a specialized computer plugged into your vehicle’s onboard computer system, also known as the Engine Control Unit (ECU). This tool communicates with the ECU and retrieves valuable data about the engine’s performance, emissions, and various subsystems. It generates error codes that give information about any issues or malfunctions the car may be experiencing.

How does a diagnostic test work?

When the diagnostic tool establishes a connection with the ECU, it retrieves trouble codes, also known as Diagnostic Trouble Codes (DTCs). These codes serve as valuable clues that help mechanics identify specific problems.

Understanding the Role of Engine Diagnostics in Car Repair

Diagnostic tests are just the starting point of the repair process. They alert where a potential problem is located, but it’s not a cure-all that ends the repair process. Skilled mechanics must still rely on their expertise and perform additional testing protocols to diagnose the issue accurately.

What systems does the car’s computer monitor?

While it may vary slightly from car model to car model, the onboard computer system generally monitors the same systems. These include the engine control unit, transmission, exhaust, ignition system, emissions control system, airbag, and fuel injection system. 

The engine control unit, or ECU, is particularly important as it adjusts many critical factors affecting fuel consumption, idle speed, and emissions.

What will a diagnostics test tell you?

A comprehensive diagnostic test can provide valuable insights into the health of your vehicle. It can pinpoint specific problems, such as a malfunctioning sensor, a misfiring cylinder, a faulty oxygen sensor, or a failing catalytic converter.

Once the computer has run the scan, it will generate an error code, identifying any specific issues your car may be experiencing. However, these codes are not a definitive diagnosis – rather, they simply give the technician a starting point of what needs to be checked and repaired. 

A diagnostics test will provide valuable information about potential issues like a faulty oxygen sensor, damaged spark plugs, or a clogged fuel injector. It can also determine any other underlying problems contributing to the car’s issues.

Should you get a diagnostics test regularly?

While routine diagnostic tests are not necessary, they can be beneficial in maintaining your vehicle’s performance and catching potential problems early on. Regular diagnostic tests can help identify minor issues before they escalate into major and costly repairs.

Erring on the side of regular testing can help your vehicle stay in good working condition. Having the test done regularly can identify and repair potential issues before they cause significant or irreversible damage. 

We recommend you follow your vehicle manufacturer’s recommendation, typically every 30,000-50,000 miles. And indeed, any time you notice a change in performance or are concerned about something specific.

What’s the benefit of having a diagnostic test?

There are many benefits to having a diagnostic test. 

To start, it can give you peace of mind knowing that your car is running smoothly. If any underlying issues are detected, the test can identify and repair the problem before it causes further damage to the vehicle. 

Having periodic diagnostic tests can help save you money on potential future repairs by identifying issues when they’re small, rather than waiting for them to become more extensive and more expensive.

Timely repairs also help extend the lifespan of your vehicle and maintain its resale value. That’s a very good idea considering today’s vehicle price is now over $48,000.

How long will a diagnostic test take?

The duration of a diagnostic test varies depending on the complexity of the problem and the expertise of the mechanic. In some cases, a diagnostic test can be completed within an hour, while more intricate issues may require additional time for thorough inspection and testing.

It’s best to consult with your mechanic to get an estimate of the expected duration for your specific situation.

How do I know if I should schedule a diagnostic test?

If you notice anything out of the ordinary with your vehicle, it’s always a good idea to schedule a diagnostic test. 

If you experience a persistent check engine light, erratic engine performance, unusual noises, or a significant decrease in fuel efficiency, it’s crucial to have your vehicle checked. Additionally, if you notice any leaks, abnormal vibrations, or odd smells, these can also be indicators of underlying problems that require professional attention.

Schedule an inspection today

Engine diagnostics can significantly help car owners identify and resolve problems with their vehicles. They can provide significant information about your car’s onboard computer systems, giving qualified technicians a better understanding of what’s happening under the hood. 

The test only takes about an hour to complete, but it can identify and repair underlying issues before they become more challenging and more expensive in the long run. By getting tests performed regularly, you might be able to save yourself a lot of money and drive your car with confidence, knowing that it’s running smoothly.

Schedule your inspection today.

10 Car Maintenance Mistakes Car Owners Make

July 3, 2023 by Denver Express Car Care

People buy new cars for a reason. Peace of mind comes with knowing every part is new, every system should work for a long time before it needs repair. 

Yet with car prices climbing, we’re holding onto our cars more than ever before. The average age of a car in the US is now up to 12.2 years.

As your car ages, it will require maintenance to keep it in good working condition. Are you making any of these car maintenance mistakes? 

Maintenance Mistake #1: Skipping car fluid inspections 

As a driver, changing the motor oil frequently is pounded into you. We have specialty stores dedicated to changing motor oil. We get that. 

Yet a car needs more than motor oil to thrive. 

  • Transmission fluid
  • Coolant
  • Brake fluid

There’s a list of fluids vital for the proper functioning of a vehicle. 

Ignoring fluid levels can lead to problems such as engine damage, overheating, and brake failure. The best place to start is by checking your owner’s manual and following the manufacturer’s guidelines. Have your car’s fluids checked and replaced at the recommended intervals.

Maintenance Mistake #2: Neglecting the air filter

The air filter plays a crucial role in keeping the engine clean by filtering out dirt, debris, and other contaminants. Over time, the air filter gets clogged, reducing airflow and compromising engine performance. Neglecting to replace the air filter can lead to decreased fuel efficiency and increased engine wear.

The air filter should be inspected and replaced regularly. Finding a trusted mechanic to bring your vehicle into regularly will help ensure the air filter is changed out per the manufacturer’s recommended intervals. It will help maintain optimal engine performance.

Worn-out brake pads can compromise your ability to stop quickly, increasing the risk of accidents. It’s crucial to monitor the thickness of your brake pads and replace them when they reach the minimum suggested guidelines recommended by the manufacturer.

Maintenance Mistake #4: Driving with a check engine light on

What’s blinking on your dashboard? The check engine light is one of the most common to stay lit after starting the car. It’s also the most commonly ignored. 

The check engine light serves as a warning sign that something is amiss with your vehicle’s engine or emissions system. Unfortunately, many car owners ignore this warning and continue driving. 

Whenever the check engine light illuminates, it’s advisable to have your vehicle inspected by a qualified mechanic to diagnose and address the underlying issue.

Maintenance Mistake #5: Overlooking tire inspections

Have you ever noticed the pilot in action when you board a flight? When he arrives at his plane, he’ll spend a few minutes walking around, verifying the different systems. 

Follow these guidelines yourself and perform inspections on your vehicle from time to time. Tires are the only point of contact between your vehicle and the road, making them crucial for safety and performance. Neglecting tire inspections can lead to uneven wear, reduced traction, and increased risk of blowouts. 

Do a visual check. Check your tire pressure, tread depth, and overall condition. Ensure that the tires are properly aligned and rotated as recommended by the manufacturer to maximize their lifespan and maintain optimal handling.

Maintenance Mistake #6: Forgetting to replace windshield wipers

Colorado weather can be unpredictable at best. Have you ever turned the windshield wipers on, only to find they don’t work? You might be low on washer fluid, or the rubber is so old it streaks across the windshield. 

Proper visibility is essential for safe driving, especially during adverse weather conditions. Unfortunately, many car owners forget to replace their windshield wipers regularly. 

Worn-out wiper blades can leave streaks, impairing visibility and compromising your safety on the road. Inspect your wiper blades periodically and replace them if they show signs of wear or deterioration.

Maintenance Mistake #7: Ignoring noises or smells

What’s that sound? What’s that smell? Unusual noises or smells coming from your vehicle should never be ignored. 

They often indicate underlying problems that require attention. Whether it’s a squealing sound from the brakes or a burning odor from the engine, ignoring these warning signs can lead to significant damage and costly repairs. If you notice any unusual noises or smells, consult a qualified mechanic to diagnose and resolve the issue promptly.

Knowing your limits and seeking professional help for complex repairs is crucial. A qualified mechanic has the expertise and tools to diagnose and fix issues correctly, ensuring your vehicle’s reliability and safety.

Maintenance Mistake #10: Taking the smallest telltale signs for granted

Sometimes, it’s the smallest signs that can indicate more significant issues with your vehicle. A small leak, a minor vibration, or a subtle change in performance may be early indicators of a more substantial problem. 

If you ignore these seemingly insignificant signs, it can result in costly repairs down the line. 

Pay attention to even the slightest changes in your vehicle’s behavior and have them inspected promptly.

Are you making these car maintenance mistakes? 

If you’ve seen yourself in any of these scenarios, it’s not too late to turn things around. 

Maintaining a car involves more than just filling up the tank and washing it regularly. By avoiding the common car maintenance mistakes mentioned above, you can prolong your vehicle’s lifespan, enhance safety on the road, and potentially save money on repairs. 

A well-maintained car performs better and provides peace of mind for a worry-free driving experience.

Car Repair Myths Debunked: Separating Fact from Fiction

June 28, 2023 by Denver Express Car Care

When you buy a new car, you expect it to run well. It’s new. 

That is a car repair myth you might find out for yourself if you’ve recently purchased a new car. 

According to the 2023 JD Power Initial Quality Study, vehicle quality continued to worsen with the 2022 line of automobiles. For 2022, the average rate of problems per 100 vehicles jumped to 180. And for 2023 – it’s already averaging 192 problems per 100 vehicles. 

New cars can have a host of problems almost as soon as you drive them off the showroom floor. Today’s cars are built with all sorts of new bells and whistles, many of them untried with limited testing. Consider yourself a beta tester – and things can sometimes go wrong.

Of course, that’s not the only car repair myth people believe. In fact, a lot of drivers believe a variety of myths that can make your car less efficient and require more maintenance over time. Have you ever believed one of these?

Myth #1 Engines require a warm-up period before you drive away

Have you ever headed out early on a cold, winter morning to start your car and let it warm up before you drive away? It’s a myth. 

Car Repair Myths Debunked: Separating Fact from Fiction

This myth stems from the era of carbureted engines, where a warm-up period was necessary to ensure proper fuel flow. Modern fuel-injected engines do not require an extended warm-up period. Idling your car for an extended period of time wastes fuel and causes unnecessary wear on the engine. 

You can start driving gently right after starting your car, and the engine will warm up faster while driving.

Myth #2 Open windows waste fuel

Today’s cars are aerodynamic by design. They’re intended to be driven as a closed circuit, windows up, everything in its place. Driving with the windows down creates a significant drag on the car, resulting in decreased fuel efficiency. Right?

Think again. While it’s true that open windows can cause some drag, the impact on fuel efficiency is generally minimal, especially at lower speeds. 

That may change a bit at higher speeds. The increased drag can have a noticeable effect. But something maybe even more important – what do you prefer?

When you’re heading out for a busy day, you may want the windows up for a quiet environment. Heading home from the beach may be the perfect time to enjoy fresh air and freedom – something you feel with the windows down. 

Cars are built for efficiency. It all averages out over time. 

Myth #3 Skip the air conditioner and roll down windows for better fuel efficiency

Contrary to popular belief, rolling down the windows and turning off the air conditioner is not always the most fuel-efficient option. At high speeds, the increased aerodynamic drag caused by open windows can offset the fuel savings from not using the air conditioner. 

Again, it’s all about preferences. How can you create the most comfortable environment for you? The change in fuel efficiency isn’t that noticeable, depending on your driving preferences. 

Myth #4 Cheaper gas can harm a car’s engine

Remember when changing the oil every 3,000 miles or three months was commonly recommended? It’s long since been a rule of thumb. 

Would it surprise you to learn that most modern cars are designed to run efficiently on regular unleaded gasoline?

Before you head to the pumps, spend a few minutes with your owner’s manual. What octane fuel does the manufacturer recommend? Using a higher octane fuel than recommended by the manufacturer will not provide any significant benefits and may be a waste of money. 

But don’t forgo recommendations. Using a lower octane fuel than recommended can potentially cause knocking or pinging. This shouldn’t cause any long-term damage, but it’s always better for your engine to treat it well.

Myth #5 Oil changes are necessary every 3,000 miles

Remember when it was commonly recommended to change the oil every 3,000 miles or three months? It’s long since been a rule of thumb. 

Advancements in oil and engine technology have extended oil change intervals for most vehicles. The frequency of oil changes depends on various factors, such as the type of oil used, driving conditions, and the manufacturer’s recommendations. 

For many modern cars, an oil change every 5,000 to 7,500 miles is sufficient. Consult your owner’s manual or contact a trusted mechanic to determine the appropriate interval for your vehicle.

Myth #6 Manual transmissions are more efficient than automatic

Today’s drivers prefer automatic over manual transmissions – 96 percent of our roadways are filled with automatic cars. 

Yet many of those drivers still believe that manual transmissions are more fuel-efficient than automatic transmissions. While this was true in the past, modern automatic transmissions have evolved significantly. 

The introduction of advanced technologies, such as continuously variable transmissions (CVT) and dual-clutch transmissions (DCT), has narrowed the fuel efficiency gap between manual and automatic transmissions. In some cases, automatic transmissions can even outperform their manual counterparts in terms of fuel economy.

Myth #7 Replace all four tires at the same time

Uh, oh, a tire is flat. When it’s time to replace a tire, all four must be replaced simultaneously. 

Or do they?

In reality, tire replacement depends on several factors, such as tread wear, tire damage, and the condition of the remaining tires. If only one tire is damaged or worn out, replacing it alone may be sufficient. However, it’s essential to maintain consistent tread depth and tire performance across all four tires for optimal handling and safety. 

Regularly monitor the condition of your tires and consult a professional if you’re unsure about their replacement.

Myth #8 New car warranties require repair and maintenance at the dealer

While it’s true that new car warranties require proper maintenance, it’s not necessary to have all repairs and maintenance performed exclusively at the dealer. As long as you follow the manufacturer’s recommended maintenance schedule and use genuine or recommended parts, you have the freedom to choose where you get your car serviced. 

Independent repair shops and qualified mechanics can perform routine maintenance and repairs without voiding your warranty. Just make sure to keep records of the maintenance and repairs performed for warranty validation.

Myth #9 Today’s cars no longer need maintenance 

Technology has made everything more efficient. Why worry about maintenance? 

While modern cars are generally more reliable and technologically advanced, they still require routine maintenance to ensure optimal performance and longevity. Regular oil changes, fluid checks, filter replacements, and inspections are essential for keeping your car in top shape. Neglecting maintenance can lead to costly repairs and decreased reliability over time.

Skip the car repair myths – maintain your vehicle every day

By debunking these common car repair myths, we hope to provide accurate information and empower you to make informed decisions about your vehicle. 

Keep your owner’s manual handy. Consult with trusted professionals regularly. And continue to enjoy a smooth and hassle-free driving experience.

The Importance of Quality Parts and Components in Car Repairs

June 21, 2023 by Denver Express Car Care

Would it surprise you to learn that not all car repair shops use quality parts and components to fit into your car? 

Maybe you’ve even experienced it yourself. You pull in and expect a specific service, only to discover a short while later that the repair wasn’t completed as discussed. 

Car repair is often considered to be one of those areas that’s overwhelming at best. You know your car needs work, but you aren’t sure who to trust. What’s a person to do? 

Types of car repair shops

Car repair shops can be categorized in one of three ways:

  • Car dealerships – mechanics at a dealer are specially trained for the brand’s cars. 
  • General repair shops – mechanics who understand the ins and outs of most vehicles, and can work on any problem as it arises. 
  • Specialized repair shops – these are chains that specialize in one item – tires, brakes, oil changes, etc. 

Drivers often use car dealerships while their cars are under warranty. Because dealerships are quite expensive, drivers usually shop around looking for more personalized service that’s easier to fit into the budget. 

The Importance of Quality Parts and Components in Car Repairs

They might rely on specialized repair chains for specific services, but quickly move to general repair shops when they require more than one service at a time. 

Then comes the difficult part – choosing a reputable car repair service that you can rely on. It’s only natural to start asking questions like:

  • Do they provide quality service? 
  • Do they use quality parts? 
  • Do they tell the truth about repair work?

Choosing high-quality parts is crucial for ensuring your car’s safety, reliability, and efficiency. Quality car parts provide many benefits, including:

Safety and Reliability

Safety should be the top priority when it comes to car repairs. Quality parts and components are designed and manufactured to meet or exceed industry standards, ensuring they perform reliably under various driving conditions. Lower quality or counterfeit parts may compromise the safety of the vehicle and its occupants.

Want examples? Using substandard brake pads may reduce stopping power, leading to longer braking distances and potentially hazardous situations. Similarly, using cheap and inferior suspension components can negatively impact the vehicle’s handling and stability. This increases the risk of accidents – something you hope never to experience. 

Investing in quality parts gives you peace of mind knowing that your vehicle is equipped with components that have undergone rigorous testing and meet strict safety standards.

Performance and Efficiency

Quality parts and components can significantly enhance the performance and efficiency of your car. Original Equipment Manufacturer (OEM) parts, designed specifically for your vehicle’s make and model, offer the best fit and compatibility. These parts are engineered to work seamlessly with the rest of the car’s systems, maximizing performance and fuel efficiency.

However, much debate exists about how well OEM parts compare to aftermarket parts. High quality aftermarket parts can often do the job equally well, helping you save money in the process. We believe it comes down to a highly skilled mechanic selecting the right part for the job. Sometimes OEM parts are best. Sometimes an aftermarket part works equally well and saves money in the process. If you have any questions about what parts are being used, have a conversation with the mechanic before the repair work is completed. 

Longevity and Cost Savings

Using quality parts and components in car repairs can contribute to the longevity of your vehicle and save you money in the long run. High-quality parts are generally more durable and reliable, reducing the likelihood of premature failures or breakdowns. By choosing quality components, you can extend the lifespan of your vehicle and avoid costly repairs that may arise from using inferior parts.

Moreover, quality parts often come with warranties that provide additional protection and reassurance. These warranties cover defects and failures within a specified period, giving you peace of mind and potential cost savings. While the initial cost of quality parts may be higher compared to their cheaper counterparts, the long-term benefits outweigh the short-term savings.

Resale Value and Brand Reputation 

Using quality components in car repairs can positively impact the resale value of your vehicle. Potential buyers often look for vehicles that have been well-maintained with genuine parts. Having a documented history of using quality components enhances your car’s perceived value and reliability, making it more appealing to buyers.

Additionally, using genuine parts from reputable manufacturers contributes to the overall brand reputation of your vehicle. Trusted automotive brands invest heavily in research and development to produce high-quality components that meet stringent standards. By utilizing these parts, you maintain the integrity of your vehicle and align with the manufacturer’s commitment to excellence.

Do you use a car repair shop that invests in quality parts?

Cars today are a significant investment. The average new car price has settled at just above $48,000. 

Maybe that’s why we’re keeping our cars longer than ever before. Studies show we keep pickup trucks for 13.6 years, SUVs for 8.5 years, and sedans for 10.3 years. That’s expected to rise significantly as cars get more expensive. 

Those statistics are just two reasons why people are becoming more involved in selecting a car repair shop that can help them keep their cars better, longer. It’s no longer about keeping a car running; it’s about keeping it in good working condition for life. 

When it comes to car repairs, the quality of the parts and components used can make a significant difference in the overall performance and longevity of the vehicle. Choosing high-quality parts is crucial for ensuring your car’s safety, reliability, and efficiency.  

If you haven’t found a repair shop to rely on, maybe it’s time. 

As a family auto repair shop, we care about the parts we use to service each vehicle and our reputation in the community. 

How can we help you keep your car in great condition?

Signs That Your Car Alternator May Be Failing

June 10, 2023 by Denver Express Car Care

Sometimes car trouble hits you at the worst time. You’re late for a meeting, turn the key, and instead of the engine firing up, all you hear is: click, click. 

Is it a dead battery?

Or is it something else? 

Today’s average vehicle is made up of more than 10,000 parts. One piece works together with another to make your entire vehicle possible. But when one part goes bad, it can impact many others. 

That click, click might not be your battery. It might be the alternator instead. 

What does an alternator do?

Have you ever experienced being stranded on the side of the road with a dead battery and had no idea what went wrong? If you are nodding your head yes, then you might have experienced a failing alternator. 

Whether you are driving a brand-new or an old one, your alternator plays a pivotal role in keeping your car running smoothly. It’s responsible for keeping the battery charged while driving; if it fails, it can cause several problems for your vehicle. 

An alternator generates electricity to power your car’s electrical system and recharge the battery. It is connected to your car’s engine through belts and pulleys to create energy when the engine is running. The alternator sends power to the battery, which keeps the car running and powers the headlights, stereo, and other accessories.

The warning signs the alternator is failing

Without a properly functioning alternator, your car’s battery would quickly drain, leaving you stranded on the side of the road. Understanding the signs that your alternator may be failing can help you address the issue before it becomes a significant problem.

Signs That Your Car Alternator May Be Failing

Dashboard battery light

Have you ever noticed a dashboard warning light that looks like a battery? That’s the alternator warning light. If it comes on, it could mean your alternator is failing. If the alternator is not producing enough voltage, the battery will not be able to recharge, causing the battery light to come on. If you notice this light illuminated while driving, addressing the issue promptly is essential to avoid further complications.

Headlight trouble

If your headlights are dimming or flickering while driving, it could be a sign that your alternator is failing.

The Role of the Alternator in Your Car’s Electrical System

June 4, 2023 by Denver Express Car Care

If you own a car, you already know that your car’s electrical system plays a vital role in keeping your vehicle functional. At the core of the electrical system is the alternator, one of the most critical components in keeping your vehicle’s electrical system performing correctly. 

Yet as a driver, you might not know much about the alternator. What does it do? What signals should you watch for and correct before it fails altogether? 

What is an alternator?

Simply put, an alternator is a device that converts mechanical energy into electrical energy. The engine powers it and ensures that the battery remains charged. It also maintains a stable voltage supply to other electrical components in your vehicle.

The alternator is usually located near the engine. It creates electrical energy from mechanical energy with an alternating current. It’s created from several components, including:

  • A voltage regulator to prevent power surges
  • A stator and rotor to produce alternating current to convert energy into electricity 
  • A cooling fan to protect the various parts from overheating

How does an alternator work?

The alternator takes the mechanical energy the engine generates through motion and turns it into electrical energy. This process is achieved using a rotor and a stator within the alternator. The rotor is a magnetic field created by a copper coil that spins along with the engine belt. The stator sits beside the rotor, takes the rotating magnetic field and uses it to produce an electrical current. Once the electrical current is generated, it flows through the car’s electrical system, powering the lights, radio, and other electrical components.

The Role of the Alternator in Your Car's Electrical System

How long does an alternator last?

Like other components on a vehicle, the alternator will only last for so long. The lifespan of an alternator may vary depending on the make and model of your vehicle and how often you use it. 

On average, alternators tend to last between five to seven years. However, if your alternator isn’t working right, it may be worth inspecting it to see if it needs replacement. If your alternator stops functioning, it could drain your car’s battery or lead to a much larger electrical failure that could wind up being a costly fix.

What symptoms surface when an alternator fails?

Several signs indicate an alternator is failing or has failed. The most common warning sign is your car battery warning light illuminating your dashboard. This light signals that an issue has arisen within the electrical system that needs attention. Other symptoms may include your car struggling to start or irregular noises or smells. If you notice these symptoms, you should get your vehicle to a mechanic as soon as possible.

Weak battery

As the alternator’s ability to charge the battery decreases, it will eventually lose its charge and weaken. This may cause the engine to struggle or even fail to start altogether.

Battery dashboard light on

A common indicator of a failing alternator is the battery dashboard light. If this light illuminates, the alternator is not charging the battery properly, and the battery is being drained.

Grinding noise

A failing alternator can also produce a grinding noise. This noise can be caused by worn bearings or failing internal parts. If the stator and rotor don’t spin correctly, they may produce an unpleasant sound. 

Dim or slow-working electrical components

If the alternator is not providing enough power to the electrical system, the car’s components, such as headlights, radio, and air conditioning, may operate at lower capacity or slow down. This can also include other systems like power windows or door locks

Flickering or pulsating headlights

A failing alternator may cause the headlights to flicker or pulse, as the alternator is not providing a consistent flow of electricity to the car’s electrical system.

Burning rubber smell

A worn-out alternator belt or a failing alternator pulley can cause a burning rubber smell. This indicates the belt or pulley is overheating due to excessive friction.

Stalling or hesitation

A weak or failing alternator can cause the engine to stall or hesitate, as the spark plugs may not receive enough power to ignite the fuel and air mixture in the combustion chamber.

Any of these symptoms should be taken seriously and should prompt you to have your vehicle inspected by a qualified mechanic. An alternator that is not functioning properly can lead to a drained battery, which can leave you stranded, and cause other issues down the road if not addressed.

How do you fix an alternator? 

A qualified mechanic should always carry out the repair or replacement of an alternator. Ensure they have experience working on automotive electrical systems.  

Before replacing an alternator, the mechanic will perform a series of diagnostic tests to determine the cause of the issue. This may include testing the battery, checking the alternator’s voltage output, and inspecting the alternator belt and pulley.

Depending on the results of the diagnostic tests, the mechanic may be able to repair the alternator by replacing faulty components such as the voltage regulator or bearings. If the alternator cannot be repaired, it must be replaced with a new or rebuilt unit.

After the installation, the mechanic will perform a series of tests to ensure the alternator functions properly. This may include checking the voltage output, inspecting the battery’s charge level, and verifying that all electrical components work as they should.

Easy peasy, and it shouldn’t take much time. You’ll be back on the road in no time. 

Have you ever had a problem with an alternator? 

While an alternator may not be a component you work with regularly, it’s crucial to your vehicle’s construction. As it fails, your car will show visible signs of failure. 

The alternator is a critical element in how your car runs, and it is vital to know when it is showing signs of wear and tear or failing altogether. Knowing what an alternator is and how it works can be very helpful when talking to a mechanic about the issues you may be experiencing. 

Keep an eye out for warning signs, and if you ever feel unsure about anything, it’s always best to take your vehicle to a mechanic to get a proper diagnosis. You can avoid costly fees and expenses by staying on top of your car’s electrical system and ensuring the alternator is doing its job.

What is a Valvetrain and How Does it Work?

May 28, 2023 by Denver Express Car Care

As drivers, we know what some car parts are for. The tires connect with the road. The steering wheel allows us to navigate turns and corners. Motor oil keeps the engine running smoothly. 

But other parts are a little more obscure. Like the valvetrain. It sounds important. But what exactly is a valvetrain, and how does it work?

What is a valvetrain?

In today’s modern cars, the valvetrain is integral to the engine’s functionality. It comprises various parts, such as valves, rocker arms, pushrods, camshafts, and lifters, that control the intake and exhaust of air and fuel in the engine. 

The valves open and close at specific intervals, allowing gasoline to enter the combustion chamber while expelling exhaust fumes. A well-maintained valvetrain ensures optimal engine performance, improving fuel efficiency, reducing emissions, and extending engine life. Therefore, it’s crucial to have a basic understanding of what a valvetrain is and how it contributes to your car’s overall performance.

How a valvetrain functions

To understand how a valvetrain functions, let’s begin with the basics of how an engine works. The engine’s pistons move up and down, creating pressure that drives a crankshaft, which powers the car’s motion. The valvetrain controls the air and fuel entering and leaving the combustion chamber, where the pistons move.

Each cylinder typically has two or more valves – an intake valve and an exhaust valve – both controlled by the valvetrain. The camshaft is a crucial part of the valvetrain and controls the timing of when the valves open and close. The camshaft rotates with the crankshaft, and its lobes push against the rocker arms attached to the valve stems, causing the valves to open and close.

The process of opening and closing valves is precisely timed to ensure that the right amount of fuel and air enters the combustion chamber while the correct amount of exhaust gasses are expelled, producing the desired power output.

Valvetrain components and what they do

A car is constructed from thousands of moving parts. The valvetrain is an intricate component with many parts coming together to keep your car operational. Parts include:

Camshaft

The camshaft is the heart of the valvetrain. It’s a rotating shaft with a series of cam lobes that control the opening and closing of the engine’s valves. As the camshaft rotates, the lobes push on the pushrods or rocker arms, causing them to move the valves up and down.

Pushrods

Pushrods are long, thin rods that connect the camshaft to the rocker arms. They transmit the motion of the cam lobe to the rocker arm, which then opens or closes the valve.

Rocker arms

Rocker arms are the pivoting levers that transfer the motion of the pushrod to the valve. They pivot on a shaft mounted on the cylinder head. The rocker arms come in various configurations, including stamped steel, cast aluminum, and roller tip designs.

What is a Valvetrain and How Does it Work?

Rocker shafts

Rocker shafts support the rocker arms and allow them to pivot smoothly. They are typically made of steel or aluminum and are mounted on the cylinder head.

Valve bridges

Valve bridges are small metal pieces that connect the intake and exhaust valves. They ensure that the valves open and close together, preventing interference between the valves.

Valves

The valves are the components that control the flow of air and fuel into the combustion chamber and the exhaust gasses out of the engine. There are typically two valves per cylinder, an intake valve, and an exhaust valve. The valves are opened and closed by the camshaft, pushrods, and rocker arms.

Valve springs

Valve springs are the coil springs that keep the valves closed when the engine is not running. They ensure that the valves close tightly against the valve seats, preventing any leakage of air or fuel.

Timing belt

The timing belt is a toothed belt that connects the camshaft to the crankshaft. It ensures that the camshaft rotates at the correct speed and in time with the crankshaft. The timing belt must be replaced periodically to prevent it from breaking and causing damage to the engine.

Belt tensioner

The belt tensioner is a component that maintains the proper tension on the timing belt. It ensures that the timing belt does not slip or jump teeth, which can cause the engine to run poorly or not at all.

Regular maintenance to keep the valvetrain at peak performance

One of the most important things you can do to keep your car’s valvetrain in peak performance is to change the oil regularly. Oil is the lifeblood of the valvetrain, and without proper lubrication, the valves can stick, causing damage to the engine. Additionally, the oil contains detergents and other additives that keep the valvetrain clean and prevent the buildup of carbon deposits.

Another essential maintenance task is to check the valve clearances regularly. Valve clearances, also known as valve lash, are the distance between the rocker arm and the valve stem when the valve is closed. Too much or too little clearance can lead to poor engine performance or damage. This is where it helps to have a mechanic you can rely on for regular maintenance. When they know a car well, they can help you maintain it over time. 

It’s also important to keep the air filter clean and replace it when necessary. A dirty air filter can reduce engine performance, causing the valves to work harder than they need to, wearing them out faster.

Is your car’s valvetrain in good working condition?

The valvetrain is a vital component of your car’s engine, and it’s essential to understand how it works to keep it well-maintained. Regular oil changes, checking valve clearances, and replacing air filters are just a few of the vital tasks required for proper valvetrain maintenance. 

By taking care of your car’s valvetrain, you can ensure optimal engine performance, prolong engine life, and save on fuel costs. So, the next time you’re behind the wheel, take a moment to appreciate the intricacies of your car’s valvetrain and give it the care it deserves.

Maintaining Your Car’s Refrigerant System For Optimal Performance

May 24, 2023 by Denver Express Car Care

The temperatures are climbing all across the Front Range. 70. 80. 90 and more. It’s record-breaking heat, and your car isn’t happy. 

What’s worse, the temperature inside your car is even hotter. One study found that a car parked in the sun can reach 95 degrees or hotter within an hour. Dashboards can reach 157 degrees, and those seats can be a scorching 123 degrees. Ouch!

All of that can take a toll on your car’s air conditioner. It’s up to the refrigerant system to ensure its optimal performance. 

What do you know about refrigerant and how it helps maintain your car’s air conditioner? What you don’t know might impact you on the hottest days of the year. 

What is car refrigerant? 

Car refrigerant is a substance responsible for cooling the air in your vehicle’s air conditioning system. It circulates through a closed loop system, absorbing heat from the cabin and expelling it outside, creating a cooler environment inside. It plays a vital role in maintaining comfortable temperatures inside the car, especially during hot weather conditions.

Maintaining Your Car's Refrigerant System For Optimal Performance

Refrigerants are typically colorless, odorless, and tasteless, making it difficult to detect when running low or leaking. That may require analysis by a professional, but there are additional things you can do. 

Are there different types of refrigerant?

Refrigerants are not all the same. Over the years, different refrigerants have been used in car air conditioning systems. The most commonly used refrigerants are R-12 (dichlorodifluoromethane), R-134a (tetrafluoromethane), and the emerging R-1234yf (2,3,3,3-tetrafluoroprop-1-ene). R-12, also known as Freon, was widely used until the 1990s but was phased out due to its adverse effects on the ozone layer.

R-134a replaced R-12 as the standard automotive refrigerant and is still widely used in vehicles today. It is a more environmentally friendly option and has a lower ozone depletion potential. R-1234yf is a newer refrigerant that offers even lower global warming potential than R-134a, making it more eco-friendly. However, not all vehicles are compatible with R-1234yf due to differences in system design and requirements.

Do all types of refrigerant work in every car?

Refrigerants are not interchangeable; they do not work in every car. The type of refrigerant your vehicle requires depends on its make, model, and the system it is equipped with. Older vehicles designed for R-12 refrigerant cannot be retrofitted to use R-134a without significant modifications to the air conditioning system.

Vehicles designed for R-134a may not be compatible with R-1234yf without system updates. It is crucial to consult your car’s manufacturer or refer to the owner’s manual to determine the appropriate refrigerant type for your vehicle. Using the wrong refrigerant can damage the system, leading to costly repairs. If you have any questions, we can help. 

What causes refrigerants to be depleted?

Refrigerant depletion can occur due to various factors. 

The most common cause is a leak in the system. Over time, wear and tear can cause tiny holes or cracks in the refrigerant lines or components. 

Exposure to extreme heat while parked in the sun can also cause refrigerants to leak. That intense heat can take its toll on many parts and components. 

Don’t think a long, grueling winter isn’t hard on your AC unit. Moisture can build up in the system over time, causing damage to the compressor, evaporator, and hoses. 

Refrigerants can gradually escape through the tiny pores of rubber hoses, o-rings, and seals. Even a small leak can result in a significant loss of refrigerant over time, compromising the system’s performance and efficiency. Regular maintenance is crucial to detect and repair leaks promptly.

How do you maintain a car air conditioner?

Have you noticed that maintenance is critical to keeping your car running and all systems checked and working well? No matter what component you’re considering or what system you may have issues with, maintenance is key to returning it to good working condition and ensuring your car always runs well.

Leak Detection – If you notice a decline in cooling performance or an unusual hissing sound, it may indicate a refrigerant leak. Have it inspected and repaired as soon as possible to prevent further depletion.

Recharging – If your car’s air conditioning system is not cooling as effectively as before, it may be a sign that the refrigerant levels are low. Recharging the system with the appropriate refrigerant might be necessary. Recharging should be done by a professional who can accurately measure and add the correct amount of refrigerant to the system.

Cabin Air Filter Maintenance – The cabin air filter plays a vital role in maintaining the air quality inside your vehicle. A clogged or dirty air filter can restrict airflow, reducing the efficiency of the air conditioning system. Regularly inspect and replace the cabin air filter according to the manufacturer’s recommendations to ensure proper airflow and system performance.

Use the System Regularly – Running your car’s air conditioning system regularly, even during cooler months, helps maintain the system’s integrity. This practice prevents seals and hoses from drying out, reducing the likelihood of leaks. It also helps circulate the refrigerant, lubricating various components and keeping them in good working condition.

Keep the Condenser Clean – The condenser is located behind the grille at the front of your car. It is responsible for releasing heat from the refrigerant. Over time, debris such as leaves, dirt, and bugs can accumulate on the condenser fins, obstructing airflow and reducing cooling efficiency. Regularly clean the condenser using compressed air or a gentle stream of water to remove debris and ensure optimal airflow.

Protect from Excessive Heat – Prolonged exposure to extreme heat can damage the refrigerant and other components of your car’s air conditioning system. Whenever possible, park your vehicle in shaded areas or use sunshades to minimize the interior temperature. This practice reduces the strain on the system and helps maintain its performance and efficiency.

Seek Professional Help – While car owners can perform some maintenance tasks, seeking professional help for complex repairs or system diagnostics is essential. Certified technicians have the expertise and specialized equipment to effectively identify and resolve issues with your car’s refrigerant system.
