The Importance of Properly Inflating Your Tires Year-Round

February 14, 2025 by Denver Express Car Care

Ever thought about your tire pressure? You should. In fact, you might have already be experiencing the reason why. 

You hop into your car, start the engine, and head out for the day without thinking twice. But what if your tires aren’t properly inflated?

Underinflated or overinflated tires affect everything from fuel efficiency to handling and braking performance. A study by the National Highway Traffic Safety Administration (NHTSA) shows that vehicles driving on tires underinflated by more than 25 percent are three times more likely to be involved in a crash related to tire problems.

Tire pressure isn’t something you should think about only when you see a warning light on your dashboard. It’s a year-round maintenance task that can make a big difference in your car’s performance, safety, and longevity.

It’s time to get your tires into top shape and keep them there. 

Proper Tire Inflation Matters For So Many Reasons

What do you enjoy the most about your car? Maybe the comfort of the ride, or the performance when you’re driving to work. All of that is related to your tires. Tires are the only point of contact between your car and the road. Proper inflation ensures they perform at their best. 

The Importance of Properly Inflating Your Tires Year-Round

But what happens when they aren’t at the correct pressure?

Better Traction & Handling

Underinflated tires increase the risk of losing control, especially on wet, icy, or snowy roads. Overinflated tires reduce the contact patch with the road, making your car more prone to skidding. Proper tire pressure ensures optimal grip and handling in all driving conditions.

Fuel Efficiency: More Miles Per Gallon

Driving with low tire pressure increases rolling resistance, forcing your engine to work harder and burn more fuel. According to the U.S. Department of Energy, underinflated tires can lower gas mileage by up to 3 percent. And that adds up over time.

Longer Tire Life

Tires aren’t cheap. If you want to get the most out of them, proper inflation is key. Overinflated tires wear out in the center, while underinflated ones wear out on the edges. Keeping them at the right pressure ensures even tread wear and extends their lifespan.

Smoother Ride Quality

Ever feel like your car bounces too much or the ride seems rougher than usual? Improper tire pressure affects ride comfort, making for a bumpier and noisier drive.

Braking Performance

Braking distance is crucial, especially in emergencies. Underinflated tires increase stopping distances, while overinflated ones reduce traction. Keeping your tires properly inflated ensures reliable braking when you need it most.

Longer Tire Life

Tires aren’t cheap. If you want to get the most out of them, proper inflation is key. Overinflated tires wear out in the center, while underinflated ones wear out on the edges. Keeping them at the right pressure ensures even tread wear and extends their lifespan.

Braking Performance

Braking distance is crucial, especially in emergencies. Underinflated tires increase stopping distances, while overinflated ones reduce traction. Keeping your tires properly inflated ensures reliable braking when you need it most.

Yes, Tire Pressure Changes Each Season

Colorado weather can be crazy at times. Sunshine one minute, followed by snow the next. Temperature variations can swing 30, 40, even 50 degrees or more in a single day. That’s challenging for your tires. 

In colder weather, tire pressure drops approximately 1 PSI (pound per square inch) for every 10-degree drop in temperature. That means if you last checked your tires in summer, they could be dangerously underinflated by winter.

In hot weather, tire pressure increases as air inside the tires expands. This can lead to overinflation, making your tires more susceptible to blowouts.

The good news? Checking and adjusting tire pressure is quick and easy. Here’s how to stay on top of it year-round:

Find the Correct Tire Pressure for Your Car

Forget the number printed on the tire sidewall—that’s the maximum pressure, not the recommended level for your car. Instead, check the sticker inside the driver’s side door or your owner’s manual for more details. Most passenger vehicles require tire pressure between 30–35 PSI, but always follow your manufacturer’s recommendations.

Use a Reliable Tire Pressure Gauge

Digital or analog, a good tire pressure gauge is an inexpensive investment that helps you keep track of your tire health. Keep one in your glove compartment for quick checks.

Check Tire Pressure Monthly (and Before Long Trips)

Make it a habit to check your tires at least once a month, especially before a road trip. Be sure to measure pressure when the tires are cold (before driving) for the most accurate reading.

Adjust Pressure as Needed

If your tires are underinflated, add air at a gas station air pump or with a portable compressor. If they’re overinflated, release air until they match the recommended PSI.

Monitor for Leaks and Damage

If a tire consistently loses pressure, check for punctures, sidewall damage, or leaks around the valve stem. Slow leaks can be a warning sign that a tire needs repair or replacement.

Rotate and Balance Your Tires

Tire rotation helps ensure even wear, while balancing prevents vibrations. Follow your car’s maintenance schedule, usually every 5,000 to 7,500 miles.

Note: You should check your tire pressure even if the car’s sensor hasn’t lit up. That’s because the tire pressure monitoring system isn’t infallible. Think of it as a backup to one of the most important parts of your vehicle. 

The Cost of Ignoring Tire Pressure

What happens if you don’t check your tire pressure regularly? A lot, actually.

  • Increased Blowout Risk: Underinflated tires generate excess heat, making them more likely to fail—especially at high speeds.
  • Wasted Fuel: Running on low-pressure tires means more frequent stops at the gas station.
  • Expensive Repairs: Uneven wear shortens tire life, meaning you’ll be replacing them sooner than necessary.
  • Safety Hazards: Poor traction and braking performance increase the risk of accidents, especially in emergency situations.

All these issues are preventable with a 5-minute monthly tire pressure check.

By making tire pressure checks a regular habit, you’ll avoid unnecessary repairs, drive more efficiently, and ensure a smooth ride year-round.

How to Handle Your Car’s Traction Control System Warning Light

February 10, 2025 by Denver Express Car Care

Modern technology is great, isn’t it? We rely on it every day in so many ways. 

Hop in your car, and you know that technology does amazing things just by turning a key or pushing a button. Thousands of parts come together and allow you to go anywhere you desire safely and comfortably. 

But that technology can also be a bit puzzling. Have you ever cruised down the road, and suddenly, your dashboard lights up with a symbol that looks like a car with squiggly lines underneath? It’s your traction control system (TCS) warning light. 

If you’re like most drivers, you might feel a moment of panic.

What does it mean? Is it dangerous? Should you pull over immediately? 

Relax—we’re here to demystify that light and help you understand what to do next.

What Is the Traction Control System?

The traction control system is a safety feature designed to prevent your car’s wheels from losing grip on the road. If you’ve ever driven on wet, icy, or uneven surfaces and felt your tires lose their grip, you know how dangerous this can be. 

How to Handle Your Car’s Traction Control System Warning Light

TCS helps maintain stability by reducing wheel spin. It works by monitoring your wheels through sensors connected to the anti-lock braking system (ABS). If it detects that a wheel is losing traction, the system can reduce engine power to slow the spinning wheel, and apply brakes to the wheel losing grip, redistributing power to the other wheels.

In essence, TCS acts like an extra layer of security, especially in slippery or hazardous driving conditions. Think of it as your copilot. 

What Does the Traction Control System Warning Light Mean?

If your copilot steps away, that can be a bit unnerving. That same feeling might arise when the TCS warning light illuminates on your dashboard. It’s your car’s way of telling you there’s an issue with the system. Depending on the circumstances, the light could mean:

Temporary Activation

If the light flashes briefly and then turns off, it’s likely the system engaged temporarily to prevent wheel slip. For example, this might happen when accelerating on a slick surface.

Persistent Illumination

If the light stays on, it indicates the traction control system is disabled or malfunctioning. While your car is still drivable, you’ll lack the added stability TCS provides, which could be risky in certain conditions.

Which have you experienced? When the light stays illuminated, it’s time to take action. 

Common Causes of a TCS Warning Light

You have a dashboard light that remains on. Now what? If it’s a TCS warning light, it can be triggered by various issues, ranging from minor glitches to more significant problems:

Slippery Road Conditions

When driving on icy, wet, or loose surfaces, the system may activate frequently. Prolonged use in these conditions can sometimes cause the system to temporarily shut off to prevent overheating.

Faulty Wheel Speed Sensors

The wheel speed sensors are critical for monitoring traction. If one or more sensors are damaged, dirty, or malfunctioning, the TCS may not function properly.

Problems with the ABS

Since TCS shares components with the anti-lock braking system, an ABS issue—like a malfunctioning pump or control module—can also trigger the TCS warning light.

Low Tire Pressure or Worn Tires

Uneven or low tire pressure affects how your wheels grip the road, potentially confusing the TCS sensors. Similarly, worn tires with insufficient tread can reduce traction, causing the system to overcompensate.

Electronic Control Unit (ECU) Errors

The ECU processes data from various sensors to control the TCS. Software glitches or faulty connections can lead to incorrect readings and trigger the warning light.

Steps to Take When Your TCS Warning Light Comes On

Even when you know the possible reasons for the TCS warning light to come on, it can still set a moment of panic deep inside. We suggest a few action steps to help you fix the problem. Here’s what to do:

Check Road Conditions

Are you driving on a slippery surface? Did the light flash briefly during acceleration? If the light turns off after the system stabilizes the vehicle, there’s no need for further action.

Inspect Your Tires

Pull over safely and examine your tires. Ensure your tires have sufficient tread to maintain grip. Check and adjust the pressure to the recommended levels in your owner’s manual. Look for signs of wear, damage, or uneven tread.

Restart Your Car

Sometimes, a simple restart can resolve temporary glitches in the TCS or ECU. Turn the car off, wait a few moments, and then restart it to see if the light goes away.

Check for ABS Issues

Is your ABS warning light also on? If so, the problem may be linked to the anti-lock braking system.

Consult Your Owner’s Manual

Your car’s manual often includes specific advice for handling warning lights. It may guide you to perform additional checks or describe what’s safe to do next.

Visit a Mechanic

If the light persists or if you notice changes in your car’s performance, it’s time to bring your vehicle to a professional. We’ll perform a diagnostic scan to retrieve error codes, inspect wheel speed sensors, the ABS system, and the ECU, and resolve the underlying issue to restore your TCS functionality.

Preventing Traction Control System Issues

Want to minimize the chances of seeing that TCS warning light in the future? Regular maintenance is key.

Maintain Your Tires

  • Rotate your tires every 5,000 to 7,500 miles.
  • Replace tires when the tread depth falls below 2/32 of an inch.
  • Ensure tire pressure matches manufacturer recommendations.

Keep Sensors Clean

  • Dirt, mud, or snow buildup can obstruct wheel speed sensors. Have them inspected and cleaned during routine maintenance.

Service the ABS and TCS

  • Schedule regular checkups for your braking and traction systems to catch potential issues early.

Drive Responsibly

  • Avoid harsh acceleration, especially on slippery surfaces. Gentle and steady driving reduces stress on the TCS.

Stay Safe with a Healthy Traction Control System

Your car’s traction control system is there to keep you safe, especially in challenging driving conditions. While a TCS warning light can be concerning, understanding its causes and addressing them promptly will ensure your car remains reliable and road-ready.

If you’re dealing with a persistent TCS warning light or want a thorough system check, schedule an appointment with us today. Our expert mechanics will diagnose the issue, restore your TCS functionality, and get you back on the road with confidence.

Don’t let a warning light slow you down—drive with the assurance that your car is in peak condition!

Tips for Preventing Overheating in Stop-and-Go Traffic

February 7, 2025 by Denver Express Car Care

Is bumper-to-bumper traffic getting you down? Is your short drive to work increasing all the time? Yes, Colorado traffic seems to be getting worse by the day. It can be aggravating, watching the minutes tick by, thinking of all the things you could be doing if you weren’t sitting in traffic. 

What happens if your car agrees? You glance down and notice the temperature gauge creeping higher and higher. Panic sets in—what if your engine overheats?

Overheating is a driver’s nightmare, especially in stop-and-go traffic, where airflow is limited, and your engine is working overtime. What do you need to know? How can you prepare now … before it happens? Let’s reduce the chances of your car overheating and avoid being stranded on the side of the road.

Why Do Cars Overheat in Stop-and-Go Traffic?

Your car’s cooling system is designed to keep the engine at an optimal operating temperature. However, stop-and-go traffic presents unique challenges:

Like limited airflow. When your car is moving, air flows through the radiator, helping to dissipate heat. In stop-and-go traffic, the lack of movement limits this natural cooling effect.

Of course, that isn’t the only thing that can happen. Frequent stops and starts put additional strain on the engine, generating more heat. 

Tips for Preventing Overheating in Stop-and-Go Traffic

And that stop-and-go traffic? That means more idling. While idling, the engine continues to produce heat, but the cooling system may struggle to keep up without adequate airflow.

Signs Your Car Is Overheating

Don’t think overheating occurs only in summer. In summer, cars are more likely to overheat due to high external temperatures. When the thermometer climbs into the 90s and 100s, your car is more likely to complain, too. The engine’s operating temperature goes up and the cooling system works harder to keep the engine at an optimal temperature. 

In winter, external temperatures are lower, but a car’s engine can still overheat. This can be from a frozen coolant system, a malfunctioning thermostat, or a faulty water pump. 

In both cases, it’s up to you to recognize the early signs of overheating can help you take action before your engine sustains damage.

  • If the needle on your temperature gauge moves into the red zone, it’s a clear sign your engine is overheating.
  • Steam or smoke escaping from under the hood indicates excessive heat.
  • A sweet, burning smell may indicate leaking coolant, while a rubbery odor could mean overheating belts.
  • The check engine or coolant warning light often illuminates on the dashboard when the engine overheats.

Tips for Preventing Overheating in Stop-and-Go Traffic

The best way to avoid an overheating engine is to prevent it altogether. Luckily, that’s a straightforward process. 

Check Your Cooling System Regularly

Your cooling system is your first line of defense against overheating. Regular maintenance ensures it’s working efficiently.

  • Inspect Coolant Levels: Low coolant is a common cause of overheating. Check the reservoir regularly and top it off with the manufacturer-recommended coolant if needed.
  • Flush the System: Over time, coolant can degrade and lose its effectiveness. Flushing and replacing it every 2-3 years prevents buildup and keeps the system clean.
  • Examine the Radiator and Hoses: Look for leaks, cracks, or corrosion in the radiator and hoses. Replace any damaged components promptly.

Keep the Radiator Clean

A dirty or clogged radiator can reduce its ability to dissipate heat effectively.

  • Clean the Fins: Remove debris, such as leaves or bugs, from the radiator fins using compressed air or a soft brush.
  • Check for Blockages: Internal blockages caused by rust or sediment can restrict coolant flow. If you suspect a blockage, consult a mechanic.

Monitor Your Thermostat and Fans

The thermostat and cooling fans play critical roles in regulating engine temperature.

  • Test the Thermostat: A faulty thermostat can get stuck closed, preventing coolant from circulating. Replace it if it’s not functioning correctly.
  • Inspect the Fans: Cooling fans draw air through the radiator when the car isn’t moving. If the fans aren’t turning on, check the fan motor, relay, or fuse.

Avoid Overloading Your Vehicle

Extra weight puts additional strain on your engine, causing it to work harder and generate more heat.

  • Travel Light: Remove unnecessary items from your car, especially if you’re driving in traffic-prone areas.
  • Distribute Weight Evenly: Proper weight distribution reduces stress on the engine and cooling system.

Use the Air Conditioner Wisely

Running the air conditioner adds to the engine’s workload, especially in traffic.

If you notice the temperature gauge rising, turn off the air conditioner and switch to the ventilation fan.

Drive Smoothly

Your driving habits have a significant impact on engine temperature.

  • Avoid Hard Acceleration: Rapid starts generate more heat. Accelerate gently to reduce engine strain.
  • Use a Steady Pace: In stop-and-go traffic, try to maintain a consistent speed to minimize frequent stops and starts.

Prepare for Traffic Jams

If you know you’ll be driving in heavy traffic, take a few extra precautions:

  • Plan Your Route: Use traffic apps to avoid congested areas when possible.
  • Carry Extra Coolant: Having a spare bottle of coolant can be a lifesaver if your levels run low unexpectedly.

What to Do If Your Engine Overheats

You’ve got a plan. You take care of your car. Sometimes it doesn’t matter; despite your best efforts, overheating can still happen. Do you know what to do to prevent further damage?

Turn Off the AC and Turn On the Heater

Switching off the air conditioner reduces engine load, while turning on the heater helps dissipate heat from the engine bay.

Pull Over Safely

Find a safe spot to pull over and turn off the engine. Allow it to cool for at least 15-30 minutes before checking under the hood.

Check Coolant Levels

Once the engine has cooled, check the coolant reservoir. If it’s low, add coolant or water, but never open the radiator cap while the engine is hot—it can cause severe burns.

Call for Help

If you’re unable to resolve the issue or notice significant leaks or damage, call a tow truck or roadside assistance.

It’s About Preventing Overheating

Stop-and-go traffic doesn’t have to mean overheating woes. Preventive maintenance and timely repairs can save you from overheating headaches.

If you’re overdue for a cooling system check or suspect an issue, schedule an appointment with us today. Our expert mechanics are here to keep your car cool and reliable on every journey.

The Importance of Regular Maintenance for High-Mileage Cars

February 3, 2025 by Denver Express Car Care

Wouldn’t it be nice to know your car will last for years? That you can buy it, drive it, and rely on it month after month, year after year, no matter how many miles the odometer registers? 

You can. 

The average age of a car on the road keeps climbing, currently 14 years. And no, these cars aren’t all sitting in a garage, only used to run errands a day or two a week. Many are driven daily, have high-mileage, and still operate well. What keeps them on the road is the way their owners handle regular maintenance. 

There are two approaches. 

1. Wait until you have a problem and then fix it.

2. Schedule regular maintenance to keep your car running well, fixing minor issues before they become major problems. 

Guess which one ensures your vehicle will last longer? 

What Is Considered a High-Mileage Car

The term “high-mileage car” doesn’t have a fixed definition—it varies based on perspective and advancements in automotive engineering. However, a car is often considered high mileage when it surpasses 100,000 to 150,000 miles on the odometer.

High-mileage cars are no longer the rarity they once were. Thanks to improvements in technology and manufacturing, many modern vehicles are built to last well beyond 200,000 miles with proper care. In fact, a high-mileage vehicle can remain reliable and efficient if maintained regularly and driven responsibly.

The Importance of Regular Maintenance for High-Mileage Cars

Just look at these examples. 

We’re not saying you should expect one million miles on the car you drive. But we are willing to bet that each of these examples had owners who scheduled regular maintenance to keep their cars in good shape!

How Are High-Mileage Cars Different From Low-Mileage Cars

It may seem a little obvious, but we thought we’d share the differences between operations on high-mileage vs low-mileage cars. 

While its core functionality remains intact, high-mileage cars require a bit more attention compared to their younger counterparts. Here’s how high-mileage cars differ:

Increased Wear and Tear

Every component in your car, from the engine to the suspension, experiences wear with every mile driven. High-mileage cars are more prone to issues like leaks, part failures, and reduced efficiency.

Fluid Degradation

Over time, essential fluids like engine oil, transmission fluid, and coolant degrade, reducing their effectiveness. Older vehicles may also be more susceptible to fluid leaks.

Reduced Efficiency

Engines in high-mileage cars may lose some efficiency due to worn components like piston rings, valves, or injectors. Regular maintenance can help mitigate these effects.

Potential for Corrosion

Vehicles driven through harsh weather or on salted roads are more likely to experience rust or corrosion, particularly on the undercarriage. Yes, just one more reason to give your car a good washing on a nice day after the infamous Colorado winter storms we get around here. 

These are just a few of the reasons why high-mileage cars need a little more attention. With the right maintenance strategy, they can remain reliable and functional for years to come.

Things To Consider as a Part Of Your Monthly and Yearly Routines

So, you want to keep your car as long as possible. Eight, ten, twelve – your car was expensive – why not get your money’s worth? If this sounds like your gameplan, just know that cars thrive on consistent care. What does that look like? Here’s what we suggest:

Monthly Maintenance Checklist

Check Fluid Levels

Ensure your oil, transmission fluid, brake fluid, and coolant are at appropriate levels. Look for signs of leaks.

Inspect Tires

Check tire pressure and tread depth. Uneven wear could indicate alignment or suspension issues.

Monitor Warning Lights

Pay attention to any dashboard warning lights and address them promptly.

Listen for Unusual Noises

Strange sounds can be early indicators of mechanical problems.

Clean the Car

Wash and wax your car to protect the paint and prevent rust, especially in winter months.

Yearly Maintenance Checklist

Change Oil and Filters

High-mileage cars benefit from more frequent oil changes. Replace the oil filter at every change, and consider using high-mileage engine oil for added protection.

Inspect Belts and Hoses

Look for cracks, fraying, or signs of wear. Replace them proactively to avoid breakdowns.

Flush Fluids

Brake fluid, coolant, and transmission fluid should be flushed and replaced according to the manufacturer’s recommendations.

Check the Battery

Ensure the terminals are clean and corrosion-free. Test the battery’s charge and replace it if it’s nearing the end of its lifespan.

Inspect the Suspension and Steering

Worn suspension components can affect handling and safety. Have a mechanic inspect shocks, struts, and bushings.

Examine the Exhaust System

Check for rust, leaks, or excessive noise. A compromised exhaust system can affect performance and emissions.

See? Easy-peasy. Just use this list to create “to-do’s” on your calendar. That makes it easy to remember. 

How To Plan Your Regular Maintenance Routine

We have a few more suggestions for you. Creating a maintenance schedule for your high-mileage car isn’t just about preventing problems. We believe it’s also about giving your car the best chance to thrive as it ages. Here’s a few more ideas:

Know Your Car’s History

If you’re not the first owner, see if you can get maintenance records from the previous owner to understand what’s been replaced or repaired. This helps you focus on areas that may need immediate attention.

Follow the Manufacturer’s Guidelines

Consult your car’s owner manual for maintenance intervals and recommended service. High-mileage cars may benefit from adjustments, like more frequent oil changes or the use of high-mileage oil.

Prioritize Key Areas

  • Engine Health: Replace spark plugs, clean fuel injectors, and ensure proper timing.
  • Transmission Care: Service the transmission and address any shifting issues promptly.
  • Brake System: Inspect pads, rotors, and fluid levels regularly to ensure stopping power.
  • Suspension and Alignment: Check for worn components and maintain proper alignment to avoid uneven tire wear.

Budget for Repairs and Upgrades

High-mileage cars may require unexpected repairs. Set aside a budget for maintenance and consider investing in upgrades, such as heavy-duty shocks, to extend the car’s lifespan.

Work with a Trusted Mechanic

Establish a relationship with a mechanic who understands your car’s needs. Regular visits can help identify potential issues before they become costly repairs.

High-Mileage Cars ARE an Asset

With proper maintenance, your car can continue to perform well and provide value long after passing the 100,000-mile mark.

Tips for Preventing Brake Fade During Heavy Usage

January 28, 2025 by Denver Express Car Care

Here in Colorado, we might think a bit differently about a car’s brake system than others across the Midwest. Driving up and down I-70 after a fun weekend can do that to you. 

Even if you’ve never experienced brake fade before, you’ve probably thought about losing your brakes as you fly down the hills. Those truck ramps off to the side, waiting for a runaway truck to help slow it down. 

What if the same happened to you? What if you couldn’t stop? 

Brake fade occurs when your car’s braking system temporarily loses effectiveness, making it harder to slow down or stop. It typically occurs under conditions of prolonged or extreme braking … hello, Colorado mountains. It can also occur during high-speed stops or in stop-and-go traffic. 

Losing your brakes is never fun. Luckily, there’s an easy way to lower your risk … regular maintenance. If you’ve never experienced brake fade before, it’s time to learn a little more about it and what you can do to solve it before it occurs.  

Learn More About Brake Fade

Brake fade is the loss of braking power due to overheating of the braking system components. When you press the brake pedal, friction is created between the brake pads and rotors (or brake shoes and drums) to slow your car. This friction generates heat. 

Under normal conditions, the braking system can dissipate this heat efficiently. However, during prolonged or intense braking, the heat generated can exceed the system’s capacity to dissipate, leading to:

Tips for Preventing Brake Fade During Heavy Usage
  • Overheated brake pads and rotors lose their ability to generate adequate friction.
  • Extreme heat can cause brake fluid to boil, creating air bubbles that reduce hydraulic pressure.
  • Excessive heat can harden the surface of the brake pads, reducing their ability to grip the rotor effectively.

There Are Several Types of Brake Fade

There’s a lot of power and energy behind the braking process. You’re driving at 40, 50, 60 miles per hour. You step on the brakes. It’s their job to reduce your speed, slow your vehicle down, and bring it safely to a stop, all the while moving that heat and energy around safely. 

Brake fade occurs when this fails. Brake fade can occur in several ways, depending on which component is affected. 

Friction Fade

This occurs when the brake pads or shoes overheat and lose their ability to generate sufficient friction against the rotors or drums. You’ll notice it as a reduction in braking power despite applying consistent or increased pedal pressure. 

Fluid Fade

Brake fluid absorbs heat and begins to boil, forming air bubbles in the brake lines. Air is compressible, unlike brake fluid, leading to a spongy or unresponsive brake pedal. When this happens, you’ll have to give a soft or spongy brake pedal more pressure to engage the brakes. 

Mechanical Fade

Heat causes components like the brake calipers, rotors, or drum linings to expand or deform temporarily. As this occurs, you’ll notice the reduced braking efficiency or uneven braking performance.  

How This Changes With Heavy Usage

You’re a Coloradan. We know how you love to play in the great outdoors. That’s why you have the large vehicle and lots of toys to enjoy nature. But here’s something to consider: Heavy usage significantly affects the likelihood and severity of brake fade. How?

Increased Heat Generation

Heavy braking – what happens when you experience frequent stops, towing heavy loads, or driving downhill for extended periods – generates more friction and heat. Heavy vehicles or loads amplify this effect, as your car’s brakes must work harder to slow down the larger mass. This excess heat can overwhelm the braking system’s ability to dissipate it, leading to friction fade or fluid fade more quickly. 

Faster Wear of Components

Constant heavy braking accelerates wear on brake pads, rotors, and fluid, reducing their effectiveness over time. That means these worn components are less able to handle stress, increasing the likelihood of brake fade during intense usage. 

Greater Strain on the Entire System

Hauling trailers or cargo increases the weight your brakes need to slow down. That amplifies the heat generated. If you’re using your truck or SUV frequently for heavy-duty purposes, the braking system often needs upgrading to handle the extra strain. Is this something you handle regularly? 

Reduced Recovery Time

Do you push your vehicle to the limits? During heavy use, brakes don’t have time to cool between applications. This cumulative heat buildup makes fade occur faster and last longer. 

Tips for Mitigating Brake Fade During Heavy Usage

You bought your vehicle for a reason. You have things to do. And your vehicle should be able to keep up with whatever you choose to dish out. 

This is where regular maintenance comes into play. Being aware of brake fade means you can do what’s necessary to prevent it. We recommend:

Use Engine Braking

Shift to a lower gear when descending steep grades to let the engine take on some of the braking load, which reduces the stress on the brakes. 

Invest in Heavy-Duty Brakes

If you frequently tow, haul, or drive in the Colorado mountains, ensure your vehicle is prepared for what it will face. High-performance brake pads are designed to withstand higher temperatures without losing friction. Slotted or drilled rotors allow better heat dissipation. Some vehicles offer or can be fitted with enhanced cooling mechanisms. Talk with a mechanic to upgrade your vehicle to meet your needs. 

Avoid Riding the Brakes

Apply brakes in short, firm bursts to give them time to cool between applications. Avoid holding the brake pedal continuously while descending hills – use downshifting or engine braking instead. 

Monitor Your Brake Fluid

Heavy use can cause brake fluid to boil if it contains moisture, leading to fluid fade. Use high-temperature-rated brake fluid and replace it more frequently if you’re regularly pushing your car’s limits. 

Regular Maintenance

Inspect your brake system more often if you frequently use your vehicle for heavy-duty tasks. Look for signs of wear, such as thinning brake pads, warped rotors, or discolored brake fluid. Replace components proactively. Don’t wait for them to fail under pressure. 

Experiencing Brake Fade

You’re reading this for a reason. Heavy usage amplifies the risks associated with brake fade and accelerates wear and tear on your braking system. 

If you’ve noticed this recently, and frequently rely on your car for towing, hauling, or other heavy-duty tasks, consult one of our professional mechanics to ensure your braking system is equipped to handle the load safely and efficiently.

How to Avoid Premature Wear on Your Car’s Brake Rotors

January 24, 2025 by Denver Express Car Care

I say, “car brakes.” What do you think? Your mind might drift to the brake pedal, knowing exactly how it reacts when you press down. Or you might think about the brake pads, remembering the last time you had them changed out. 

Yet few people consider the entire brake system and how vital every piece is. Like brake rotors. Those shiny discs that sit behind your wheels. They play an equally essential role in stopping your car.

What happens when they wear prematurely? A bumpy ride, reduced braking efficiency, and potentially costly repairs. Not fun, right? 

So, what can you do to ensure they stay in good working condition for as long as possible? Glad you asked. Traditionally, brake rotors last between 30,000 and 70,000 miles – check your owner’s manual for your specific car. This is average. How long they last depends on factors such as driving style, road conditions, and the brake rotors you install on your car.  

What Are Brake Rotors and Why Are They Important?

Brake rotors are also sometimes called brake discs. They are circular metal components attached to each wheel – look behind the spokes, and you’ll see them there. When you press the brake pedal, the brake pads clamp down on the rotors, creating friction that slows the wheels and brings your car to a stop. Yep, pretty important to your overall braking system.

How to Avoid Premature Wear on Your Car’s Brake Rotors

The rotors must endure significant heat and pressure every time you brake. That makes them susceptible to wear over time. Worn rotors don’t just affect your stopping power—they can also lead to uneven braking, vibrations, and increased wear on other components. None of which is good. 

If you’ve ever felt your car shake when coming to a stop, chances are your rotors are trying to tell you something.

Signs of Premature Rotor Wear

We get it; maintenance is something you sometimes forget. You’re busy – you’ve been meaning to schedule an appointment, but there’s always so much to do. 

Now is the time to take action. 

You’re here reading for a reason. Premature rotor wear can show up in several different ways. Before diving into how to prevent rotor wear, let’s look at the signs that your rotors might already be in trouble:

  • Vibrations or Pulsing When Braking: A warped rotor can cause uneven braking, leading to noticeable vibrations in the brake pedal or steering wheel.
  • Squealing or Grinding Noises: These sounds often indicate that the brake pads have worn down and are scraping against the rotor.
  • Visible Grooves or Scoring: If you can see or feel ridges on the surface of your rotors, they’ve likely been damaged by worn-out pads or debris.
  • Increased Stopping Distance: If your car takes longer to stop than it used to, worn rotors could be the culprit.
  • Brake Warning Light: In some cars, a warning light may illuminate if there’s an issue with the braking system.

Noticing any of these symptoms? It’s time to address the issue before it becomes more severe. 

Causes of Premature Rotor Wear

Don’t think you’re doing something wrong. There are many reasons why some brake rotors wear out faster than others. The most common culprits include:

  • Poor-Quality Rotors or Pads: Cheap materials may save you money upfront, but they’re more prone to wear and may not withstand heavy use.
  • Improper Installation: Rotors that aren’t installed correctly can wear unevenly or fail prematurely.
  • Aggressive Driving: Frequent hard braking generates excess heat, which can warp the rotors and accelerate wear.
  • Worn Brake Pads: Pads that aren’t replaced in time can damage the rotor surface, creating grooves and reducing braking efficiency.
  • Neglected Maintenance: Ignoring routine brake inspections can allow minor issues to escalate, leading to rotor damage.

Tips for Preventing Premature Wear on Brake Rotors

See anything in that list that reminds you of your situation? That’s your first step in fixing it. Now that you know what causes premature wear, let’s talk about how to prevent it. Here are some tips to help you extend the life of your brake rotors:

Avoid Hard Braking Whenever Possible

Hard, sudden stops generate excessive heat that can warp the rotors over time. While emergencies happen, you can reduce wear by braking gently and allowing plenty of space between your car and the vehicle in front of you.

Pro Tip: Use engine braking when descending steep hills to reduce reliance on your brake system.

Replace Brake Pads Before They Wear Out

Brake pads act as a protective barrier between the calipers and rotors. When the pads wear down, the calipers come into direct contact with the rotors, causing grooves and damage.

What to Do: Check your brake pads regularly and replace them when they reach 2-3mm in thickness.

Choose High-Quality Components

Not all rotors and pads are created equal. Investing in high-quality components ensures better performance, durability, and heat resistance.

Consider Upgrades: Slotted rotors dissipate heat more effectively and are ideal for high-performance or heavy-use vehicles. Ceramic brake pads produce less dust and are gentler on rotors compared to metallic pads.

Break In New Rotors and Pads Properly

When you install new brake components, they need time to bed in (or break in). This process ensures a smooth surface on the rotors and helps the pads wear evenly.

How to Bed In Brakes: Perform several gentle stops from 30-40 mph, gradually increasing braking force. Allow the brakes to cool between stops.

Keep Your Rotors Clean

Dirt, road salt, and debris can accelerate wear on your brake rotors. Keeping your rotors clean helps maintain their effectiveness and prevents corrosion.

Maintenance Tip: Regularly wash your car’s wheels and undercarriage, especially after driving in winter conditions or on dirt roads.

Check and Adjust Brake Calipers

Misaligned or sticking calipers can cause uneven pressure on the rotors, leading to premature wear.

What to Do: Have your calipers inspected during routine maintenance. A mechanic can adjust or replace them if necessary.

Schedule Regular Brake Inspections

Preventive maintenance is the key to avoiding costly repairs. Regular brake inspections can catch minor issues before they escalate.

When to Inspect: We suggest every 12,000 miles or as recommended in your owner’s manual. And before long road trips or after heavy usage, like towing or mountain driving.

The Cost of Ignoring Rotor Maintenance

We’re just going to say it: There is a cost to ignoring rotor maintenance. If you ignore brake rotor maintenance, it can lead to:

  • Increased Repair Costs: Damaged rotors often require replacement, which is more expensive than routine maintenance.
  • Reduced Safety: Worn rotors decrease stopping power, putting you and others at risk.
  • Tire Damage: Uneven braking can cause irregular tire wear, leading to additional expenses.

If you’re still reading this, it’s time to take action. Give us a call today and set up an appointment. We’ll inspect your rotors and pads for wear. We’ll let you know what’s wrong and different approaches to fix it. 

Remember, your safety is everything. Your car’s brake rotors are a vital part of its safety and performance. With proper care and maintenance, you can prevent premature wear.

Understanding the Importance of Your Car’s Air Intake System

January 21, 2025 by Denver Express Car Care

Your car’s engine is a complex machine that relies on a perfect balance of air and fuel to run efficiently. But have you ever thought about how air gets to your engine? This is where the air intake system comes into play.

Often overlooked, the air intake system plays a critical role in your vehicle’s performance. It ensures the engine receives the right amount of clean air, optimizing combustion for power, efficiency, and reduced emissions.

What do you need to know about your car’s air intake system? It might not be as top-of-mind as your car’s brakes or tires, but it can’t run efficiently without it. A few minutes in learning how it works is all it takes for you to keep it in top shape.  

What Is the Air Intake System?

The air intake system is responsible for delivering clean, filtered air to your engine. You need it to breathe; your car needs it for the combustion process. It combines with fuel to create the energy needed to power your car.

Understanding the Importance of Your Car’s Air Intake System

A typical air intake system includes:

  • Air Filter: Traps dirt, debris, and contaminants before they reach the engine.
  • Mass Airflow Sensor (MAF): Measures the amount of air entering the engine and sends this information to the engine control unit (ECU).
  • Throttle Body: Controls the airflow into the engine based on your accelerator input.
  • Intake Manifold: Distributes air evenly to each cylinder for combustion.

Together, these components ensure that the right amount of clean air mixes with fuel for efficient combustion.

Why Your Air Intake System Is Important

You can’t survive without oxygen – your car can’t survive without air intake either. A well-functioning air intake system is vital for several reasons:

Optimized Combustion

The air intake system ensures the right air-fuel ratio, which is critical for efficient combustion. Proper combustion improves engine performance, fuel efficiency, and power output.

Enhanced Fuel Efficiency

When the air intake system is clean and functioning correctly, the engine doesn’t have to work as hard to compensate for poor airflow. This results in better fuel economy and fewer trips to the gas station.

Reduced Emissions

A clean air intake system helps maintain the correct air-fuel mixture, reducing harmful emissions. This is especially important for meeting environmental standards and passing emissions tests.

Improved Engine Longevity

By keeping debris and contaminants out of the engine, the air intake system prevents wear and tear on internal components, extending the engine’s lifespan.

Consistent Engine Performance

A well-maintained air intake system ensures smooth acceleration, steady idling, and optimal power delivery, providing a better driving experience.

Signs of Air Intake System Problems

Like any car component, the air intake system can develop issues over time. Here are some common signs that it may need attention:

Reduced Fuel Efficiency

If your car’s mileage suddenly drops, it could be due to a clogged air filter or malfunctioning airflow sensor.

Decreased Engine Performance

Sluggish acceleration, rough idling, or reduced power output often point to restricted airflow caused by a dirty intake system.

Check Engine Light

The mass airflow sensor plays a key role in monitoring air intake. If it malfunctions, it may trigger the check engine light.

Strange Noises

Whistling or hissing noises could indicate a leak or crack in the intake manifold or tubing.

Black Smoke or Sooty Exhaust

An imbalanced air-fuel mixture can lead to incomplete combustion, producing visible black smoke from the exhaust.

Common Air Intake System Issues

Like every other system inside your vehicle, the air intake system will wear down over time. Several factors can affect the performance of your air intake system, including:

  • Clogged Air Filter: A dirty or clogged air filter restricts airflow, forcing the engine to work harder and reducing efficiency.
  • Faulty MAF Sensor: A malfunctioning mass airflow sensor can send incorrect data to the ECU, disrupting the air-fuel balance.
  • Leaks in the Intake Manifold: Cracks or leaks in the manifold can lead to unmetered air entering the system, causing performance issues.
  • Dirt or Debris Build-Up: Over time, dust and debris can accumulate in the intake tubing or throttle body, restricting airflow.

How to Maintain Your Air Intake System

Want to avoid air intake problems? Maintenance is the key. Keeping your air intake system in good condition is essential for your car’s performance and longevity. Here are some tips to help:

Check and Replace the Air Filter

Inspect your air filter regularly and replace it as recommended by your car’s manufacturer. A clean air filter is the first line of defense against contaminants.

Clean the Throttle Body

Over time, carbon deposits can build up in the throttle body, affecting airflow and throttle response. Cleaning it during routine maintenance can help prevent these issues.

Inspect the MAF Sensor

Ensure the mass airflow sensor is clean and functioning correctly. Use a specialized MAF cleaner if needed, but handle it carefully to avoid damage.

Check for Leaks

Inspect the intake manifold and hoses for cracks, leaks, or loose connections. Address any issues promptly to prevent unmetered air from entering the system.

Use High-Quality Fuel

Good-quality fuel can reduce carbon buildup in the intake system, keeping components cleaner for longer.

Schedule Regular Maintenance

Have your air intake system inspected during routine maintenance appointments. A professional mechanic can catch and resolve issues before they escalate.

When to Seek Professional Help

While some air intake maintenance tasks are DIY-friendly, others require professional expertise. Visit a mechanic if you notice:

  • Persistent check engine light or diagnostic trouble codes
  • Significant drops in fuel efficiency or performance
  • Strange noises from the intake system
  • Visible damage to the intake manifold or hoses

Don’t Ignore Your Air Intake System

Your car’s air intake system is a critical component that ensures efficient combustion, fuel efficiency, and reduced emissions. By recognizing the signs of issues and following a regular maintenance schedule, you can keep your car running smoothly and prevent costly repairs.

How to Prevent Common Issues with Automatic Transmissions

January 18, 2025 by Denver Express Car Care

It’s been a long time since most of us drove a manual transmission. Pushing the clutch in, adjusting your speed, staying in action throughout the drive – it all seems so difficult now. 

And most drivers agree. Manuals now make up less than 1 percent of all new cars sold. When people buy new cars, they want ease, they want to get in and drive. They want automatic transmissions. 

You agree? 

We get it; automatic transmissions give you a smooth, hassle-free driving experience. But like any mechanical system, they’re not without their quirks. When an automatic transmission starts acting up, it’s not only inconvenient—it can also lead to costly repairs.

Fortunately, with a bit of care and attention, you can avoid many common transmission problems. Do you know the common causes of transmission trouble? And maybe more importantly, how to recognize early warning signs and how to prevent issues before they happen?

Understanding Your Automatic Transmission

Your car’s transmission is responsible for transferring power from the engine to the wheels, adjusting gear ratios to provide the right amount of power for various driving conditions. Automatic transmissions do this seamlessly, without the need for a clutch or manual gear shifts.

How to Prevent Common Issues with Automatic Transmissions

Take a peek under the hood. You’ll find all the components for an automatic transmission there. It’s a complex system made up of:

  • Gears to allow your car to accelerate and decelerate smoothly.
  • Hydraulic system that uses transmission fluid to operate the clutch packs and control gears.
  • Torque converter to transfer engine power to the transmission while allowing the car to idle.
  • Electronic Components, sensors, and control modules to ensure precise shifting and smooth operation.

When any of these components fail, you’ll notice problems with your vehicle’s performance.

Exploring Common Issues with Automatic Transmissions

If you’ve been driving for a while, chances are you’ve experienced one of these common issues with automatic transmissions before. 

Transmission Slipping

You press the gas, but the engine revs without the car accelerating as expected. This is often due to worn-out clutch packs or low transmission fluid.

Delayed or Hard Shifting

If you feel a noticeable delay or jerk when shifting gears, it could be a sign of a failing solenoid, a dirty transmission valve body, or fluid issues.

Overheating

Excessive heat is the number one enemy of your transmission. It can cause fluid breakdown, wear on internal components, and even complete transmission failure.

Fluid Leaks

Transmission fluid is vital for cooling and lubrication. A leak can lead to low fluid levels, causing overheating and mechanical damage.

Check Engine Light

Many transmission issues trigger the check engine light. Codes related to solenoids, fluid pressure, or temperature can help pinpoint the problem.

Recognize any of the above? That’s the first step in prevention. 

How to Prevent Transmission Problems

Cars on the road are aging. That’s a testament to engineering and how much better cars are made today. Thirty years ago, the average passenger car made it just over 8 years; today it’s pushing 13.6 years. 

The problem lies with keeping a car well-maintained. The mechanics of a car may mean you can drive longer, but if you don’t keep up with maintenance, costly repairs will be close behind. The best way to avoid costly repairs is to take proactive steps to care for your transmission. Here’s how:

Check and Replace Transmission Fluid Regularly

Transmission fluid is critical for lubrication, cooling, and hydraulic operation. Over time, it degrades and collects debris. How often? Check your owner’s manual, but most vehicles need a transmission fluid change every 30,000 to 60,000 miles. Use the dipstick to ensure fluid levels are adequate and look for discoloration (dark or burnt-smelling fluid needs replacement).

Avoid Overheating Your Transmission

Heat is a major cause of transmission wear. Driving habits and external conditions can significantly affect the temperature. Install an auxiliary transmission cooler if you regularly tow or haul heavy loads. Avoid stop-and-go driving in hot weather whenever possible. Don’t “ride” the brakes or overuse the accelerator.

Be Mindful of Driving Habits

How you drive affects your transmission’s lifespan. Avoid sudden starts and stops, which stress the transmission. Come to a complete stop before shifting between reverse and drive. Don’t drive with your hand on the gear selector—it can lead to unnecessary wear on internal components.

Fix Leaks Immediately

Transmission leaks often start small but can lead to major damage if ignored. Check for puddles of red or brown fluid under your car. Inspect seals, gaskets, and cooler lines regularly. Have any leaks repaired promptly by a professional mechanic.

Service the Transmission on Schedule

Regular maintenance is key to preventing transmission problems. Have the transmission inspected during routine service appointments. Replace the transmission filter (if your car has one) and clean the pan to remove debris. Update the software for electronic control modules, if recommended by your car’s manufacturer.

Signs Your Transmission Needs Attention

We say it a lot around here: Spending a few minutes listening and observing your car each day will benefit you. Pilots do a preflight check before every flight. While that might not be necessary when you’re in and out of your car each day, a couple times a week could save you. That’s because even with good maintenance, problems can still arise. 

Recognizing early warning signs can help you address issues before they become serious. You might notice:

  • Shuddering or Vibration: Often felt during acceleration, this can indicate torque converter issues or worn-out transmission mounts.
  • Unusual Noises: Grinding, whining, or humming noises may suggest internal component wear.
  • Burning Smell: Overheated transmission fluid produces a distinct burnt odor.
  • Fluid Discoloration: Healthy transmission fluid is typically red or pink. Dark or brown fluid indicates contamination.
  • Gear Slippage or Delays: If your car struggles to shift gears or slips out of gear, have it inspected immediately.

When to Call a Professional

While some maintenance tasks are DIY-friendly, most transmission issues require professional expertise:

  • Persistent Symptoms: If you experience ongoing slipping, hard shifts, or overheating, it’s time to schedule an inspection.
  • Fluid Flush or Replacement: Flushing the transmission requires specialized equipment and should only be done by a trained mechanic.
  • Software Updates: Modern transmissions rely on complex software that may need updates or reprogramming.

One of our professional mechanics will use diagnostic tools to identify problems, recommend repairs, and ensure your transmission remains in peak condition.

If your transmission is acting up or you’re overdue for service, don’t wait—schedule an appointment with us today. Our expert mechanics can diagnose, repair, and maintain your transmission, keeping you on the road with confidence.

The Importance of Regularly Servicing Your Car’s Fuel Pump

January 14, 2025 by Denver Express Car Care

What do you think about when you pull up to the pump? Do you think about the day ahead? All the work you have to do? Getting the kids to their activities? What’s for dinner?

Those few minutes of standing idle can bring up a lot of “to-do’s.” But have you ever stopped to think much about your car’s fuel pump and all that it does to ensure your car goes? 

Probably not. We get it – fuel pumps aren’t a glamorous component. In fact, you might not have thought about it at all. 

You should. Like any of the other thousands of car parts, the fuel pump is essential to keeping your car running for years. Service it regularly, and you’ll decrease the chance of it giving you problems. Or moving from a small repair to a larger problem that takes more time and more dollars to solve. 

How Your Car’s Fuel Pump Works

Its name says a lot. Fuel pumps are a critical component of the fuel delivery system. It moves fuel from the gas tank to the engine. But it does more than that – it ensures the engine receives the right amount of fuel at the correct pressure for optimal combustion. (Yep, it isn’t free-flow like your garden hose.)

The Importance of Regularly Servicing Your Car’s Fuel Pump

Depending on the car you own, your car will have one of two different types of fuel pumps.

A mechanical fuel pump is on older vehicles. It’s found in carbureted engines. It operates via the engine’s camshaft or a crankshaft lobe, and creates a suction effect to draw fuel from the tank up into the carburetor. 

An electric fuel pump is included on today’s more modern vehicles. You’ll find it in fuel-injected engines. It’s typically located inside the fuel tank, and operates electronically to maintain consistent fuel pressure for the injectors. 

When you turn the key or press the start button, the car’s electronic control unit activates the fuel pump. A relay switch powers on and sends electrical power to the fuel pump. 

That tells the fuel pump to move into action. It uses an internal motor to create suction, drawing fuel from the gas tank through a fuel filter. This filter keeps debris from entering the pump. 

The pump pressurizes the fuel to a level specified by the engine’s design. This is a crucial part of the process – the injectors need this to spray the correct amount of fuel into the combustion chamber. 

Once that occurs, this pressurized fuel travels through the fuel lines to the fuel injectors (or carburetors). The fuel pressure regulator maintains a consistent pressure, adjusting based on how you’re driving and what the engine demands. 

It doesn’t end once the engine is running. The pump stays in action supplying fuel at a steady rate to match the engine’s RPMs. Every time your driving conditions change, the fuel pump changes its workload. 

What You Need To Know About A Failing Fuel Pump

Now you know how important a fuel pump’s job is. (In case you didn’t before!) Its main job is to transfer fuel from the gas tank to the engine. Of course, a variety of things can go wrong with that process. 

A fuel pump doesn’t usually fail suddenly. Instead, it gives off warning signs, symptoms that, if you catch early, can allow you to fix it before it causes more damage. Luckily, these warning signs are things you’ll notice. 

Difficulty Starting

Nothing is more frustrating than turning the key or pushing the button and nothing happens. A failing fuel pump struggles to deliver fuel, which in turn makes it hard for your engine to start. It might feel like the engine is cranking longer than usual, or not turning over at all. 

Engine Sputtering

You’re driving along, thinking about your day ahead, and your car sputters while driving at higher speeds. This is a sign the pump isn’t maintaining proper fuel pressure. This isn’t something that will occur continuously once it starts. That makes it tricky to diagnose, or having a mechanic recreate it when you bring the car in. Be sure to tell us when and where the problem occurs, and how long it’s been happening. 

Loss of Power 

When you put your car in stressful situations – driving up a big hill or towing your boat for a fun-filled weekend – this can stress a failing fuel pump. If it doesn’t supply the right levels of fuel, you’ll notice it as loss of power. 

Whining Noise

Nothing is as annoying as a whining noise coming from somewhere on your vehicle. Trace where it’s coming from. Is it in the fuel tank? It could mean the pump is wearing down. 

Poor Fuel Efficiency

If a malfunctioning fuel pump delivers too much or too little fuel, your engine will run inefficiently. Track your mileage each time you fill-up the tank. Notice a change without a reason for it? It might be the fuel pump. 

Check Engine Light

We list this at the end because a check engine light can mean a host of different issues. One of which might be a failing fuel pump. Inconsistent fuel pressure will trigger the check engine light. When it lights up, it’s best to let one of our mechanics trace where the problem lies. 

Causes of Fuel Pump Failure

Just looking at the above warning signs probably has alerted you to what causes the problem. But it’s worth noting:

  • Running low on fuel – driving on a near-empty tank can cause the pump to overheat and draw in debris from the bottom of the tank. 
  • Clogged fuel filter – the pump will have to work harder. 
  • Electrical issues – corroded connectors, frayed wiring, or a blown fuel pump can all interrupt the pump’s operation.
  • Contaminated fuel – dirt, water, or other impurities can clog the pump and reduce its efficiency. 
  • Wear and tear – every component on your car will wear out. 

But there is something that prevents the damage that comes from continually driving on a failing fuel pump: Maintenance. 

Maintenance – The Key To a Healthy Car

Hopefully you’ve learned more about the fuel pump by reading this. Chances are, you might have noticed something within your vehicle. Basic troubleshooting can be done at home – you should always be aware of how your vehicle drives. Noticing changes can be the difference between a quick maintenance fix and a significant problem. 

That said, fuel pump issues often require professional expertise to get to the heart of the problem. Have you:

  • Experienced persistent stalling or power loss?
  • Have a car that won’t start despite having plenty of fuel?
  • Noticed any of the warning signs above, and want to be proactive in repairs?

It’s time to give us a call. Schedule an appointment with us today. Our expert mechanics can diagnose the problem and get your car back on the road.

How to Identify and Address Engine Oil Leaks

January 10, 2025 by Denver Express Car Care

People often buy new cars to avoid potential problems. But as mechanics, we know problems can arise quicker than you think. 

Think about your daily drive. Chances are in the past few weeks, you’ve:

  • Slammed on the brakes
  • Hit the accelerator to speed past a car
  • Hit a pothole
  • Taken a speed bump a little too fast

It’s called driving. We take each day’s challenges as they present themselves. And for your car, it can cause wear and tear to all of the thousands of parts. 

What’s the most important part of any car? While you could make a good argument for many of the parts, we feel the engine is close to the top. Without the engine, you won’t go. 

The engine is the heart of what makes your vehicle operate. And it can be impacted by every step you take throughout your days and nights. 

It’s an Engine Oil Leak – How Do You Know?

Chances are you’ve taken a peek at engine oil before, even if you’ve never changed the oil yourself. Open a can, and you’ll see it’s typically an amber to light brown color, and has a slick texture. This makes it easy to identify. 

How to Identify and Address Engine Oil Leaks

Most people notice oil leaks by a simple visual inspection. This is where it benefits you to develop a routine. When you park in a garage or driveway, pay attention to what happens underneath the vehicle. Look for puddles as you drive away. You can also pop the hood and look at the engine block, especially around seals or on the oil pan. 

If your car is leaking oil rapidly, you’ll notice the puddles. Slow leaks are harder to see. But you can notice it if your motor oil decreases rapidly, and you have to top off the oil without seeing noticeable puddles under the car. 

What’s that smell? A burning oil smell often indicates oil leaking onto hot engine components like the exhaust manifold. 

Or maybe your car starts smoking. A bluish smoke from the exhaust could indicate oil is legging into the combustion chamber, often due to worn piston rings or valve seals. White smoke from under the hood could indicate oil burning off a hot surface. 

And then there’s the dashboard icon “oil pressure” light. If it turns on, it’s telling you your car is experiencing a significant loss of oil. When was your last oil change? If it was recently, it could be an oil leak. 

Engine Oil Leaks – Where Do They Come From?

The good thing about car maintenance is it’s predictable. When you notice an issue, it leads to a problem. It can be tricky with some symptoms – they can signal multiple problems. But a well-trained mechanic knows how to ask the right questions and can quickly get to the root of the problem. 

What produces an engine oil leak? It could be:

Valve cover gasket

This component sits on top of the engine, sealing the valve cover to the cylinder head. Over time, this gasket can become brittle or cracked, which allows oil to seep out. When this happens, you’ll usually see oil pooling on top of the engine or dripping down its sides. 

Oil pan gasket

This part seals the oil pan to the bottom of the engine. A lot of things can happen to it as it sits closer to the road. Damage from road debris, overtightened bolts, or natural wear and tear can all impact it over time. If you notice oil underneath your car after parking for a while, it’s a sign of an oil pan leak. 

Front and rear seals

The front seal is at the front of the crankshaft near the timing cover, and the rear main seal is at the back of the crankshaft between the engine and transmission. Over time, they wear out. If your vehicle is high mileage and you haven’t replaced them in the past, it could be the seals. You’ll most likely notice it by finding oil dripping near the front of the engine or between the engine and transmission.  

Oil filter

The oil filter is typically screwed onto the engine block. It’s commonly replaced when you bring your car in for an oil change. Sometimes it’s improperly installed, or the threads are damaged when it’s put back into place. If it hasn’t been changed in a while, it could have a worn-out seal. If you see oil leaking from the filter area after a recent oil change, it could need adjustment or replacement. 

Oil drain plug

Wouldn’t it be nice if every maintenance item was accomplished with precision? If you’ve owned a car for years, you know a lot goes into repair. Sometimes mechanics are rushed. And let’s face it – not all repair shops are reputable. At the bottom of the oil pan is a drain plug used for draining oil during a change. If it’s improperly sealed, or has a worn or damaged washer, it might not fit perfectly back into place. This means oil could be dripping from the bottom of the oil pan. 

Timing cover gasket

Your car has a timing chain or belt cover located at the front of the engine. Sometimes the seals wear down from excessive engine heat breaking down the gasket material. When this happens, oil leaks at the front of the engine. 

Positive Crankcase Ventilation (PCV) System

There are a lot of parts in today’s car engines. Take a look, and you’ll find hoses and valves connected to the engine to manage all sorts of processes, including internal pressure. The PCV system can get clogged or malfunction, which creates excessive pressure, forcing oil out through weak seals. You’ll notice it if an oil leak is accompanied by increased engine pressure, or you can visibly see oil around the valve area. 

Fixing Oil Leaks

Now that you know more about engine oil leaks, there are two things you can do to protect your car from future problems:

1. Perform a visual check periodically to ensure nothing looks out of place, worn down, or broken. Awareness is the first step in good maintenance. 

2. Keep up with regular maintenance. A well-maintained car is less likely to have problems over time because you fix and repair things before they grow in significance. 

When you notice an oil leak – no matter where it is – fixing it prevents future problems. It:

  • Prevents engine damage
  • Avoided bigger repairs
  • Ensures safety
  • Reduces environmental impact

Regular maintenance and inspections are your best defense against leaks. During oil changes, have your mechanic inspect common leak areas and keep your car’s seals and gaskets in good condition. 

That’s one of the best reasons to use a reputable mechanic. Get to know our service today.
