How The Colorado Climate Impacts Your Car Battery

August 4, 2021 by Denver Express Car Care

If you’ve ever been stranded because of a dead car battery, you know it’s not a lot of fun.

What causes it?

Age is only one factor that determines how well the battery will operate. What you might not have considered before is how the Colorado climate impacts your car battery.

Think of all Colorado weather can dish out. Just recently, Denver broke a 145-year-old record as temperatures climbed above 100 degrees for the fifth time this year. But warmth isn’t the only thing Front Range residents experience. Looking back through history, temperatures have dropped down as low as 29 degrees below zero.

Think these wild and crazy temperatures don’t impact the performance of your car battery? Think again.

Yet which is worse: heat or cold? Which climate impacts your car battery more?

What hot weather does to a car battery

While most people assume cold weather has the most impact on the performance of a car battery, summertime temperatures can wreak havoc too. That’s because high temperatures weaken the battery because of heat.

As temperatures climb, if you were to reach under the hood and record how hot it is, you would find it rises as high as 140 degrees or higher. Under that amount of extreme heat, battery fluid starts to evaporate, which can damage the internal structure of the battery.

Extreme temperature can also cause the voltage regulator and other charging components to malfunction, ultimately overcharging the battery system. This slows function and ultimately means the battery fails faster than its stated life.

Heat can also build inside and allow the lead plates inside the battery to corrode. Corrosion leads to deterioration, and ultimately failure.

What cold weather does to a car battery

How The Colorado Climate Impacts Your Car Battery

While car batteries can die at any time, with or without extreme temperatures, as winter moves in and the temperatures continue to dive, it can break down the internal components of a battery.

Car batteries aren’t something you replace like motor oil. Instead, car batteries can last three to seven years. That means a car battery will experience heat buildup during summer months, only to turn around and face freezing conditions in the winter. That cyclical beating can take its toll.

Cold weather can reduce the capacity of the battery by as much as 20 percent as temperatures drop to freezing, and as much as 50 percent when we start setting record lows. This reduction in capacity lowers battery output, which weakens the process of starting the car.

Cold temperatures also cause motor oil to thicken and solidify, making it harder for the engine to turn over. That forces the battery to work even harder, even though capacity is struggling for power.

A battery doesn’t power your vehicle. Instead, it’s used as a charge to turn the engine over, and provides power to the accessories like car windows and radio. As you drive your car, it recharges the battery, so it’s ready for your next outing. In cold weather, this recharging process slows down. That means you’ll have to drive further to accomplish the same recharge process. If you only head out on short errands, it might not be enough to keep the battery working efficiently.

The coldest days are also the shortest days. Cold brings out dreary weather, cloudy skies, and sunrise and sunset to shorten considerably. That means you’ll use things like headlights, windshield wipers, and heater functions more than ever. This increases the battery load at a time where the recharge rate is reduced too.

How to keep your car battery healthy all year long

Car batteries are not something you have to maintain; they simply need to be replaced every three to seven years. While you will find some batteries that have a water level indicator, allowing you to see the battery’s water level, most are sealed.

Still, it’s worth your time to pop the hood from time to time and check out the condition of your battery. Make sure that the battery and its posts are clean and free from dirt and engine grease. Dirt and grease act as a conductor, meaning they’ll lower battery power.

You’ll also want to ensure there isn’t corrosion anywhere on or near the battery. Battery corrosion often takes on a blueish tint. If enough corrosion builds up, it acts as an insulator, which prevents current flow in your battery.

To reduce the chances of impact from extreme temperatures, pay attention to where you park. If possible, park in a garage. Look for spots that are shaded by trees or buildings. This keeps the effect of sunlight to a minimum.

How to know if your car battery is weak

In the same way that the human body breaks down in record-setting temperatures, you’ll notice similar impact on your vehicle. High temperatures make us more susceptible to dehydration; the heat dries us out. Inside a battery, the liquid can evaporate as it experiences high heat, especially for long periods of time. This weakens the battery’s charge, and speeds up deterioration.

This isn’t an overnight process. Just like other systems on your vehicle, your car battery will give off warning signs as it starts to fail.

As you start your car, listen to the engine cranking over. Does it take longer to start?
The check engine or battery light may illuminate for short periods.
If you have a battery with a water-level indicator, this fluid level will be low.
The battery case may appear bloated or swollen.
The battery posts have corrosion.
You start to notice accessories like headlights appear dim and aren’t working at top levels.
Your battery is three years old or older.

Just because your battery stated a specific life span, doesn’t mean you’ll see it. It depends on driving conditions too. As you near the three-year mark, it often makes sense just to replace the battery if you start to notice any of the above symptoms frequently.

Wonder if Colorado’s climate is impacting the way your car battery performs? Bring it in. We can check your battery and determine if it’s still functioning correctly, making it a solid and dependable part of your vehicle. If it needs replacing, we can help there too.

Don’t get stranded – check your battery instead.

Is It Bad For My Car If I Run Out Of Gas?

July 28, 2021 by Denver Express Car Care

There are two types of drivers in the world: the ones that prefer to fill up the gas tank the moment their vehicle’s gas gauge nudges towards a quarter tank, and the ones who prefer to push the limit and drive it down as close to empty as possible.

Running out of gas is never fun. Depending on your current destination, it can leave you stranded in compromising places. It can make you late, and even put you in danger.

If you have a running out of gas story, chances are you remember the details of what happened. But have you stopped to think about your car? What goes on underneath the hood when there’s no more gas to feed the system? Does it hurt the engine? How about the other mechanics?

Today’s vehicles are finely tuned pieces of equipment with specific parts that help push fuel to the engine. If fuel no longer exists within the system, these components can quickly break down.

Where the process starts

You might assume that from the moment the gas tank empties, the car screeches to a halt and no longer works. It doesn’t work that way.

Instead, traces of gasoline continue to feed the system. The car will start showing signs that gas is no longer running through the system in the expected quantities. It may have power surges, engine sputtering, or even engine backfire. And in between it all, you’ll also notice a loss of power. This is your cue to get to safety. Pull to the right and get to safety as quickly as possible.

This process may be further complicated by the fact that your hydraulic power to your brakes and steering systems start failing as well. It won’t completely take away your steering or brakes, but you’ll certainly notice a difference. It will require additional effort on your part. If you have electric power steering, it will continue to function from the car’s battery, so you’ll have more control and power over other types of vehicles.

What goes on underneath the hood

If you start to notice the difference, you can only imagine what’s going on with the mechanics of your vehicle.

Is It Bad For My Car If I Run Out Of Gas?

A car is designed for safety. It will do everything it can to keep you safe. When your car runs out of gas, the engine ceases to work. The loss of power will cause hydraulic assist to help with steering and brakes for a short time to get you to safety. It won’t cause damage to those components. But without gas flowing through the system, it can cause extensive damage quickly that surfaces as costly repairs.

Why?

Because running out of gas damages the fuel delivery system. Today’s vehicles are intricately designed to work together, fed by electronics and technology to ensure every piece is efficient as possible. Today’s modern cars are equipped with an electronic fuel pump that resides in the gas tank. That fuel pump stays in good working condition by using the gas to both keep the tank cool and provide proper lubrication. If no gas exists, there isn’t anything left to perform this function. With a minimal amount of gas in the tank, the fuel pump is very likely to overheat and fail.

That in itself can be a very costly repair. But it gets worse.

As this process occurs, the fuel pump is, in essence, self-destructing. As it’s trying to perform its function and can’t, it can shed a variety of debris that makes its way into the fuel system. That spreads the possibility of destruction.

The problems that occur when you run out of gas

Your fuel pump is only the beginning of where the damage can occur. Most car manufacturers today recommend filling up your gas tank at a quarter tank. Never let it go much lower to help keep an adequate supply of gasoline in the system to do its job. It’ll make your fuel pump last longer, and will ensure all working parts are well lubricated.

But as gas runs lower, the fuel pump starts running into problems, followed by other possible conditions.

The fuel injectors may also be impacted. Over time, debris and other impurities can create sediment that falls to the bottom of the gas tank. It’s the fuel filter’s job to filter this all out to prevent it from moving further into the engine. But when the fuel level drops too low, the impurities can make their way into the fuel lines, clogging the fuel injectors, which are tiny nozzles that spray gas into the engine.

Like the fuel pump, the fuel injectors may not display symptoms right away. If your car won’t start after running out of gas previously, it’s usually a problem with either the fuel pump or fuel injectors.

To start your car after running out of gas, don’t turn the key and crank the engine right away. After refilling the gas tank, turn the key to “on” without cranking the engine. Then turn it back off. Do this a few times to help prime the fuel pump with plenty of gasoline before you crank the engine. This helps remove any air that has entered the fuel lines as a result of being without gasoline.

If this doesn’t work, it’s time to let a mechanic check out the entire system. A qualified technician can ensure fuel injectors are properly working, and help restore power to your engine.

What to do when your car runs out of gas

Prevention is everything when it comes to keeping your car in good working condition. Pay attention to the gas gauge. As it nears a quarter tank, make plans to stop at the nearest fuel station to add gasoline back into the tank.

Yet if you do find yourself running out of gas, first and foremost is to stay calm. Find a safe place to pull over where you aren’t putting yourself or others at risk. If possible, exit the highway and find an open area or parking lot to stay free of traffic.

Turn on your hazard lights. This will help warn other drivers that your car is temporarily a hazard to driving, and will help warn them to stay clear. This is especially important if you are near traffic and you could become a problem.

Call for help. This is what roadside assistance is made for. You can rely on friends and family too if they are nearby.

Then have your car inspected to ensure there is no damage. Fixing minor problems early will ensure they don’t escalate and turn into larger problems.

Have Advanced Driver-Assistance Systems? Here’s How To Maintain Them

July 24, 2021 by Denver Express Car Care

Just a few years ago, the thought of having a car do the work for you was still more hopeful than reality. That didn’t stop sci-fi movies from showing us what would be possible. Flying cars. Cars that drive themselves. Cars that did everything for you.

While we might not be able to kick back in the backseat and get work done on the way to our jobs, we have come a long way with technology. Today’s car manufacturers are competing, trying to be first to market with all kinds of modern tools that make driving safer and easier.

Most new cars come equipped with advanced driver-assistance systems (ADAS). They add to the complexity of how your car runs, and more importantly, to the ongoing maintenance of your vehicle.

What is ADAS?

ADAS – advanced driver-assistance systems – are technological features designed to increase safety and drivability of your vehicle. When properly designed, these systems are installed to work together with the driver to improve functionality, and increase the ability to react to dangers on the road.

Safety is key. ADAS is designed to provide warnings of potential dangers, automate portions of certain aspects of driving, and give drivers ample time to react and safely gain control over the vehicle.

Some are built standard into a vehicle in production, while others are added aftermarket, allowing consumers to personalize based on their preferences and needs.

How does ADAS work?

ADAS is the result of years – decades -of safety improvements. Over time, manufacturers have created things like three-point seatbelts, shatterproof glass, airbags, and more to make the driving experience safer, minimize injury, and reduce risk for all on the road. ADAS takes it a step farther by using three advanced technologies to keep a car safe as it moves about.

Have Advanced Driver-Assistance Systems? Here’s How To Maintain Them

Ultrasound tracks the immediate space around the vehicle.
Cameras provide surround view and offer things like park assist.
Radar, sensors, lidar, and other technology, can physically respond faster than a driver, creating warning systems that potentially alert dangers.

Some of the most common ADAS applications include:

Adaptive cruise control (ACC) – allowing you to maintain your speed on long stretches of road.
Adaptive light control – adapts the exterior lights to the conditions of the road.
Automatic parking – uses sensors and cameras to avoid blind spots when parking.
Navigation system – provides on-screen instructions and prompts to help you follow directions on your route.
Night vision – helps you see things that might otherwise be difficult to see. Uses both infrared and thermal energy to help you avoid animals, cars, and other objects.
Automatic emergency braking – helps you avoid danger by breaking as necessary.
Driver drowsiness detection – uses sensors to detect driver’s attention and alerts using warning signals as necessary.

Does your car have ADAS?

ADAS is not the same as having autonomous driving. Many cars today have a variety of features, including advanced driver-assistance systems. If you’re not sure what ADAS your car comes equipped with, there are a few ways to check.

Start with your owner’s manual. It might be collecting dust in your glove compartment, yet this guide is one of the most important indicators that came with your car. It can guide you to all kinds of information, including knowing what systems you have, and how to take care of them throughout the life of the vehicle.

Walk around your vehicle. Sometimes you can tell what ADAS systems you have simply by walking around your car. Check places like the tailgate, the side mirrors, rearview mirror, and front bumper. Do you see tiny cameras? That’s a sign of an ADAS system.

Talk with your mechanic. The next time you drop off your car, talk about which systems you have in place. We can help point them out, and provide you with proper maintenance schedules for them.

Scheduling a vehicle alignment

As a driver, you’re probably familiar with alignments. A wheel alignment is a computerized process that calibrates and aligns all four wheels to ensure it drives straight. Often, these aren’t noticeable adjustments. Instead, technicians use sensitive equipment to ensure each wheel angle is adjusted to match manufacturer’s specifications. If you continue to drive with improper alignment, it can wear your tires faster, and also decrease overall safety while you drive. If you want to prolong the life of your vehicle, getting proper maintenance ensures everything is working correctly.

While wheel alignment is performed using computerized equipment, ADAS alignment moves to another level. It requires specialized equipment and a fully trained technician to ensure proper ADAS alignment. Since ADAS uses technology to control things like brakes, cruise control, and steering, it also requires a special alignment process called a Safety Systems Alignment.

A Safety Systems Alignment adjusts the angles of the tire, calibrates the ADAS cameras, sensors, and radar system that help control the technological systems and components. If they aren’t in proper alignment, they cannot function properly, putting you at risk. For example, if the rear camera system is out of sync, it can’t track your wheel angle to help you reverse.

This isn’t something just anyone can do. It requires state of the art equipment, a highly skilled technician, and additional time to ensure your vehicle is up to par with your vehicle’s manufacturer’s guidelines.

Do you need a Safety Systems Alignment?

When your wheels are out of alignment, several warning signals appear to alert you to potential problems. You might notice your car drifts to one side or the other as you drive straight. Or your steering wheel is crooked while going straight.

That’s not always possible with ADAS. Your vehicle’s wheels may be in alignment, but with one of the ADAS features not working, it can steer you into a dangerous situation.

The best way to ensure your ADAS is working correctly is with regular maintenance. Just like you get frequent oil changes, or rotate the tires every few thousand miles, a check-up to ensure your ADAS is working correctly will ensure the safety of you and your passengers.

Short Distance Driving? Here’s How It Affects Your Car

July 21, 2021 by Denver Express Car Care

How much do you drive each day?

Lots of people create a lifestyle where they don’t spend a lot of time in their vehicles. They live close to work. They walk. They work from home.

Driving means taking the car to the grocery store … just a few miles away. Or maybe to pick up the kids from school … a few miles away.

According to the US Department of Transportation’s Federal Highway Administration, the average person drives around 13,500 miles per year, which equates to just over 1,000 miles per month.

Yet you know in your heart even that’s high. You just don’t drive.

What does that do to your vehicle? Should you still follow maintenance guidelines according to mileage, even if it’ll take you many years to reach what manufacturers suggest?

Let’s start with your warranty

If you have a newer car that’s still under warranty, you’re stuck with following the manufacturer’s guidelines to ensure your car maintains the suggested servicing schedule. You’ll void the warranty if you don’t. Pay attention to that as you purchase a vehicle, as some spell out maintenance schedules using different guidelines.

If you aren’t sure, now is the time to pull out your owner’s manual and read all about it.

Once your vehicle is out of warranty, then you can start to develop your own service routine depending on the type of driving you do. Keep in mind that it’s still important to bring your car in for service periodically. A vehicle left sitting unused can wear out parts in different ways. Rubber can harden. Oil can go bad. Parts can deteriorate simply by not being put into use.

Short Distance Driving? Here’s How It Affects Your Car

Instead of waiting for something to happen, it’s better to find a trusted resource who can help you monitor your vehicle and help you decide the right maintenance routine for you. Going with an independent mechanic can provide you with a trusted resource whose goal is to help you maintain your vehicle. Dealers are notorious for pushing you into service you don’t need, upgrading to new vehicles every chance they get. A reputable independent mechanic wants to increase the lifespan of your current vehicle, and to help ensure it does so without causing problems while you’re on the road.

Short distance driving damages engine oil

If you were to pop the hood on your vehicle and take a look underneath, you would find the engine is made from a variety of metal parts. Metal expands every time the temperature increases. An engine is created by piecing together a crankshaft, valves, pistons, con-rods, rings, cams – parts put together carefully to meet certain guidelines that are adhered to in a variety of conditions. They’re calibrated to ensure they work together to keep your vehicle operating smoothly, no matter what conditions it faces.

Motor oil is a thick, slow-moving flow designed for lubrication. It flows throughout the system every time your vehicle is put into operation. As the engine heats, this oil becomes less dense, which allows it to flow freely throughout and lubricate the internal components to keep them operating efficiently.

When these engine parts are cold, they don’t operate right. There isn’t enough lubrication to give each part the clearance necessary to work to the best of its ability. It takes time for the motor oil to warm, flow freely throughout the system, properly lubricate the entire system, and allow the engine to work to the best of its ability.

Additionally, motor oil also uses this generated heat to rid itself of moisture and other byproducts. If your vehicle rarely reaches the desired temperatures, these contaminants aren’t removed, meaning the motor oil increasingly has the potential to compromise the integrity of your vehicle as well as overall performance.

Short distance driving damages battery life

The biggest boost of energy comes from starting up your vehicle. When you turn the key (or press the button), it creates high demand from your battery.

As you drive, the alternator recharges the battery, so it’s ready for action the next time you start up your car. When you take short trips, the alternator doesn’t have a chance to fully recharge the battery, weakening the overall effectiveness with every trip.

Much like your engine needs time to warm up and reach its optimal operating temperature, so does the alternator. If the battery isn’t recharged properly, it pushes rapid depletion into motion, meaning your battery life decreases with every short trip.

Weak batteries can impact how well your vehicle starts up each time you turn the key. But it impacts other items on your car as well. The battery also operates your vehicle’s accessory, which means your headlamps might not be as bright, or your heated seats might be impacted.

Wear dates

Manufacturers list wear dates because many drivers use that as a gauge for maintenance and repair. And if you drive average distances or more each year, these guidelines are a good indication of things to watch for as you drive.

Yet if you’re a short distance driver, don’t be lulled into a false sense of security just because your car rarely leaves its parking spot. Parts wear down whether they are constantly in use or not. They just wear down differently.

No matter how much you drive each year, it’s important to create a maintenance schedule and stick with it.

Work with a trusted mechanic to ensure your vehicle is well maintained, has fresh oil on a rotating basis, and parts are well cared for no matter how much action they see during a year.

We can help you keep your car in good working condition, no matter how much you drive.

What a Shaking Steering Wheel Means

July 14, 2021 by Denver Express Car Care

Shake, rattle, and roll. Throw in a catchy beat, and you have the makings of a great song.

But if you start feeling your steering wheel shaking while you drive, that can be the start of something you won’t be singing about for very long.

A shaking steering wheel is a symptom of a bigger problem. From bad tires to worn out brakes, there are a variety of issues that could be causing your steering wheel to shake. If you feel shaking, start noticing when it occurs. That can help lead to where the problem lies.

Tires out of balance

One of the most common reasons that might start your steering wheel shaking starts with your tires. They may be out of alignment or out of balance, which sends shaking through your vehicle and into your steering wheel.

If your tires are out of balance, you won’t notice this as you’re pulling out of the driveway, or moving at low speeds due to traffic. But as you pick up speed, the shaking will increase. That’s because tires out of balance start becoming a bigger problem the faster you drive. Slow down, and it goes away.

The first thing to check is a visual inspection of all four tires. Are they properly inflated? Is one of them flat? Your car is designed to operate with all four tires evenly connected to the road as you drive. If one of them has lower air pressure than the others, it can throw the balance of your car off.

If all tires are inflated correctly, the next thing to check is the tread on the tires. In order to keep the tread even on all four tires, it’s important to get them rotated periodically throughout the year. You can have this done at the same time as an oil change. This will ensure even wear for the life of your tires. It also keeps your car evenly connected to the road, meaning a smoother, safer drive for you.

If the problem persists, it’s time to look at other potential problems.

Worn brake pads

Have you noticed that your steering wheel shakes only after you press down on the brake pedal? It might be a sign of worn brake pads.

As you apply the brake pedal, a caliper applies pressure to the brake pad, which in turn connects with the rotor to slow you down. This slows you down until ultimately, you come to a stop. If anything happens during this process, you might feel a shake coming through the steering wheel.

If it’s your brake pads, it’s usually because they are old, work, or dirty and can no longer grip the rotor effectively to bring your vehicle to a stop. The brake pad connects unevenly, which causes the skipping movement which vibrates up into your steering wheel.

Calipers are designed to last. The problem usually stems from the brake pads, which have to be replaced on average about every 10,000 to 20,000 miles. It can also be from the brake rotors, which may need replacing every 70,000 or so miles. This depends on your driving conditions, how you drive, the weight of your vehicle, among other things.

Suspension

The suspension can also be a common occurrence for a shaking steering wheel. This is especially true with vehicles that aren’t properly maintained, and haven’t been closely evaluated by a mechanic over time. That’s because suspension problems rarely surface overnight. Instead, they develop slowly over time.

What can cause it? It might be a loose tie rod, or a ball joint that wiggles out of position. It might start with an odd, subtle noise, one you put off because you don’t notice changes right away in the way your car operates. This is also why it’s important to pay attention to any changes in the way your vehicle operates, and provide any noticeable differences to the mechanic in charge of working on your car. It can lead to pinpointing a problem that might not have surfaced without it.

Dry guide pins

Guide pins are part of the brake calipers. Over time, they can slow down from dirt and lack of lubrication. To keep them performing well, they need to be periodically cleaned and lubricated or they become dry and corroded. This means they don’t apply the correct pressure as you press down on the brake pedal, which can cause the brake pad to connect with the rotor at the wrong angle. And when that happens, it produces a vibrating steering wheel.

This is detailed work. A trusted mechanic will inspect the entire brake system, including the caliper housing to ensure it’s handling the lubricant correctly throughout the process. If a problem exists, correcting it early will ensure parts don’t wear down before their time.

Do you have a shaking steering wheel?

Once you notice even a slight shake, it’s hard to ignore it. Don’t. Even a slight shake from time to time is a warning sign of future problems.

Do a search online and you’ll find all kinds of horror stories about faulty equipment. In almost every case, horror stories are caused by people who ignored the warning signals.

Even a tiny shake is trying to alert you to a problem. Take note of the details and bring it in. We can properly diagnose it, find the origination point of the problem, and fix it before it has a chance to grow.

The best course of action will depend on the specific problem. But if you catch it early, you’ll reduce the chances of having an expensive problem that moves to different locations throughout your vehicle.

While every part of your vehicle is important in helping to keep you safe and secure, any indication of a problem with your braking system should be checked immediately. If a problem threatens the longevity or safety of your car, fix it early to ensure you’re back on the road safely again.

Just in time to turn up the radio and start singing your favorite tunes once again.

When It’s Time To Schedule a Diagnostic Test For Your Car

July 7, 2021 by Denver Express Car Care

The human body is a complex machine. It has an array of parts and systems that work together to keep you healthy and strong.

In many ways, today’s automobiles closely resemble the human body. It’s a complicated network of more than 30,000 parts, all creating systems that allow you to travel safely wherever you need to go throughout your day.

While cars used to operate with fairly simple systems, now it’s a complex network that relies on modern technology. It’s no longer possible to pop the hood, take a glance underneath, and know what’s wrong.

In modern medicine, a diagnostic test is a procedure that is used to identify specific areas of weakness in order to determine a condition or disease. Diagnostic tests for vehicles are used in a similar manner.

A diagnostic test used on a car, truck, SUV, or CUV can help an auto mechanic determine what’s wrong with the vehicle. It can also give them a snapshot of the vehicle’s overall health. If you’re buying a used car, for example, this snapshot can be a valuable piece of information in helping you determine whether to sign on the dotted line.

By utilizing specialized diagnostic equipment, it allows a technician to pinpoint problem areas within the various systems quickly, and get to the root of the problem better, faster.

Sounds like a good idea to run a diagnostic test, right?

According to Kelly Blue Book, the average price of a new vehicle in the US here in 2021 is $40,472. The average vehicle produced today is expected to last 11.4 years, while the average length of time drivers keep a new vehicle is at 71.4 months.

Doesn’t it make sense to keep your car in as good working condition as possible?

It’s time for an annual checkup

When It’s Time To Schedule a Diagnostic Test For Your Car

When you go in for your annual checkup, it gives your doctor a chance to assess your vitals. They can check your blood pressure, assess your weight, perform blood tests to determine how healthy you are from the inside out.

A diagnostic test for your vehicle works in much the same manner. If you bring your vehicle in annually, a diagnostic test can pinpoint weaknesses in the system, and give you a chance to fix it before the problem escalates. The sooner you make a repair, the less chance it has of breaking other parts around it, potentially stranding you by the side of the road.

If you partner with an auto mechanic right here in Denver, you can be sure to build a relationship with someone who understands your vehicle, can help you make the best decisions for you and your wallet, as well as ensure your car remains in the best condition possible for as long as you own it.

Pay attention to the check engine light

The average vehicle produced today comes with more than two dozen computer modules working together in the form of a network, linking all the components together to make your car run. In order to keep you apprised of potential problems, each of these computer modules is linked to a dashboard light, signaling to you there is a problem you shouldn’t ignore.

While you should take all of them seriously, one of the most crucial is the check engine light. It’s one of the most common to illuminate on the dashboard. It’s also one of the least specific. That’s because the check engine light is connected to so many different parts, and can be warning you of many different potential problems. It could be something as simple as a loose gas cap, or be more urgent in telling you there’s a loss of compression, which could quickly lead to engine failure.

When this little light comes on, don’t ignore it. Schedule a diagnostic test and bring it in for inspection. This one simple test can use technology to get to the root of the problem, make the necessary changes, and get you back on the road in as little time as possible.

Listen for changes in noises

Cars are built with a network of parts placed together to keep you safe as you drive each day. The first time you started up your car, you paid attention to the different sounds it made. You could feel the engine turn over. You could hear the gears as they clicked into place. All of these sounds became ingrained in your mind. It became your normal.

Over time, as a vehicle begins to wear down, it can start creating sounds out of the ordinary. This isn’t something that happens quickly; in most cases, it’s a slow process that happens over time.

It’s easy to ignore these noises. With so many other things going on in your daily life, why pay attention to small changes that are hard to hear? Yet these little noises are your warning sign of bigger problems.

Do you hear a squeak, grinding sounds, a rattle, or a hum? Has it been intensifying over time?

It’s time to schedule a diagnostic test.

Before you buy a used car

Given how well cars are put together today, it sometimes makes sense to buy a used car instead of new. New cars are expensive; used cars can save you money. A new car built today can operate well for more than a decade, and provide several hundred thousand miles of driving.

But how do you know if you’re sitting in a quality car or a lemon? While the condition of the car is a good representation of how well it was maintained, it isn’t everything. A diagnostic test can alert you to minor problems and help you choose wisely before putting money down on a used car. It’s an easy way to get third-party approval before you complete the transaction.

Have you made diagnostic testing a part of your regular routine?

Think of it as a checkup for your vehicle. It can help you understand how well your car is operating, allow you to make smaller repairs before they escalate in damage and price.

Schedule your diagnostic test today.

What Exhaust Problems Are Telling You About Your Car

July 3, 2021 by Denver Express Car Care

Sitting in traffic gives you a chance to notice potential problems with the cars around you.

The car in front of you might have smoke pouring out of the tailpipe, with an odor that has you reaching to control the inside cabin’s airflow.

Another car might have water leaking from the tailpipe, a trail forming as it drives along.

A car drives by with sounds louder than usual. Maybe you hear a loud roaring sound when someone starts up a car nearby.

Still another seems to operate perfectly. It quietly buzzes along the road, appearing to operate efficiently.

Exhaust issues can quickly turn into problems. Priority in fixing them means you’ll stop potentially costly repair bills before they escalate, as well as reduce the risk of health problems if the gas enters your cabin.

Before we talk about ways of fixing car exhaust problems, let’s learn a little more about the basics.

How the exhaust system works

The purpose of a car’s exhaust system is to limit emissions, noise, and vibrations, and be a release system for combustion gases. It also improves performance of the engine, and fuel consumption. It’s made up of a series of components that stretch the length of your car, starting with the engine and running to the rear exhaust pipe.

Depending on the make and model of your vehicle, the design of the exhaust system may vary. However, they all work in a similar manner, to pull the harmful exhaust gases from the engine, which are produced as the engine operates. The gases produced include three toxic gases: carbon monoxide, nitrogen oxide, and nitrogen monoxide.

The system starts with the manifold, which has the job of collecting exhaust fumes from the engine. It acts as a funnel to divert gases from cylinders in the engine through a single opening referred to as the front pipe.

The gases then travel through a catalytic converter which removes the harmful elements and converts them to inert gases. They pass through a silencer or muffler, which reduces the sound waves and produces a quieter car. This is one of the biggest warning signs – if you hear a loud car, there’s a chance it has a problem with the exhaust system.

The tailpipe is the exit point for exhaust fumes. This is what takes toxic fumes away from the vehicle, and keeps the passengers inside safe from harm.

Common problems with an exhaust system

One of the most common problems within the exhaust system is corrosion of various components, including the front pipe. The silencer is also prone to corrosion damage, which is one of the biggest reasons you might experience more engine noise.

Because the exhaust system stretches the length of the vehicle on the undercarriage, it can also be impacted if you hit something because of low clearance. There are many joints that can loosen, break, or cause vibrations over time, and can affect performance. If you hear a hissing noise, it might be a leak.

Signs you have problems with the exhaust system

Like other parts of your vehicle, when something goes wrong in the exhaust system, it creates specific problems to alert you early, to give you time to fix the problem before it escalates.

Decreased power and acceleration – one of the first issues you’ll notice with a compromised exhaust system is a decrease in performance of your engine. You won’t be able to accelerate well, and you won’t get the same power you’ve grown accustomed to while owning your car.

Decreased fuel efficiency – when your vehicle isn’t performing well, you’ll also start to notice a decrease in fuel efficiency. Your car will have to work harder to achieve the same functions, which will take more fuel to accomplish the same goals. Watch your mileage numbers every time you fill up. Significant decreases in efficiency are your car’s way of telling you there’s a problem.

A noisy engine – if any part of the exhaust system breaks down, it will impact the noise level of the engine. A faulty manifold gasket, for example, will cause an exhaust leak that sounds like a hissing or tapping sound. It will increase in decibel levels from a cold start, or as you accelerate.

A burning smell – if the manifold gasket fails and begins to leak, the heat produced could impact the wiring or any of the many plastic pieces located underneath the hood. As the heat takes hold, they start to burn and it releases a distinct burning smell.

A gas smell – if one of the exhaust pipes or tubes is damaged and starts to leak, it can allow a gas smell to circulate inside your vehicle while you drive.

A loose or dragging exhaust pipe – if one or more of the brackets holding up the tailpipe are damaged or loosened, it can allow the exhaust pipe to hang or drag on the ground. When this happens, it’s important to fix it immediately, as it can quickly damage other parts of your vehicle through vibrations. If it falls off completely, it’s a danger to you and the other drivers around you.

Keep your vehicle in good working condition through regular inspections

Although the exhaust system is vulnerable to both damage and corrosion, a well cared for vehicle will rarely have problems with the exhaust system with regular driving alone. Modern vehicles are designed for an exhaust system to last for 100,000 miles or longer with regular maintenance. Unless your car is damaged or you take your vehicle four-wheel driving, it should stay trouble-free for years.

When you bring your car in for regular maintenance, we can use diagnostic tests to determine where minor problems exist. If we find a problem with the exhaust system, we can complete the required maintenance to bring the system back to good working condition, and get you on the road again in no time.

Tire Rotation – Should You Rotate Regularly, or Not?

June 24, 2021 by Denver Express Car Care

With every part of your vehicle, there’s a set of guidelines to ensure they remain in top condition. As they wear, there are also suggested plans of action for repair and replacement, to ensure you’re never stranded by the side of the road.

One of the most common reasons you’ll find people pulled over along the highway is for a flat or blown tire. It’s one of the most common repairs, because your tires are constantly under pressure.

When you purchase new tires, they promise you they’ll last 40,000, 50,000, even 60,000 miles or longer. The reality of that depends on how well you care for the tires during that time frame.

No, you can’t put new tires on and forget about them. Tire rotation is a crucial part of giving tires their longest lifespan.

What is tire rotation?

Tire rotation means periodically moving the tires to a different position on your vehicle. You should rotate them as recommended by your vehicle’s manufacturer, or about every 5,000 miles. To make the process easy, you might consider bringing your vehicle in for an oil change, and have the tires rotated at the same time.

When a mechanic rotates your tires, it also gives them a chance to inspect them for other potential problems. They can check air pressure, look for visible signs of damage, and check their tread depth. If you’ve noticed anything unusual with the way your car drives, let your mechanic know. It’s a perfect time for them to inspect the tires in more detail to ensure a safe drive for you in the coming months.

Why should tire rotation be a part of your regular routine?

Tire rotation is important for several reasons.

Banner For Car Wheel Business. 3d render and illustration. Wheel black background.

Potentially the biggest reason is to ensure you get the full mileage from your tires. By rotating them and putting tires in new positions every few thousand miles, it ensures the tread life is maximized. Tires on the front of a front wheel drive vehicle take a larger portion of the friction as you move down the road. Each wheel could have its own little quirks about pressure and the way it handles on the road. Rotating them changes the way each tire connects, and gives them the best chance at an extended life.

Also, even pressure on a tire ensures even tread wear throughout the life of a tire. Tread depth helps with traction on the road. Because we have a variety of weather conditions here in Colorado, connection is everything. With proper tread depth, you’ll ensure the safest levels of cornering and braking performance your vehicle can offer. That means a safer drive for you, your passengers, and the people around you.

If you have an all-wheel drive car, keeping your tires in balance means less stress on the drivetrain. And that can amount to less maintenance over time.

Is 5,000 miles suggested or mandatory?

We see all kinds of advice online that suggests mileage markers as a guideline instead of a rule. Ultimately, it’s about two things.

First, you should always consult your owner’s manual for maintenance requirements. The people who built your vehicle have the best understanding of how to maintain it. When in doubt, heed their guidance and follow their advice.

Second, Nothing is ever cast in stone. However, if you wish to keep your car in the best condition possible, and avoid potential problems that could impact your drive, erring on the side of being consistent with checkups will never hurt.

Allowing a mechanic to inspect your vehicle regularly gives them a chance to find potential problems before they escalate. With tire rotation, they can determine any potential problem with your tire before it gives you trouble on the road.

It reduces the cost of an expensive repair, giving you a chance to fix it before more goes wrong with your vehicle.

Other reasons to rotate your tires regularly

While your tires are an expensive part of your vehicle, parts you’ll be replacing regularly as you drive, there are other reasons to inspect them regularly.

While regular tire rotation can ensure your tires the longest life, it also ensures your safety. If tires don’t wear evenly, it can increase your risk of a blowout. At a minimum, it will impact the performance of how you drive, and can lower your gas mileage, making you spend more at the pump each time.

Your tires are also largely responsible for braking. Think of your tires as a protection system for the wheels. If tires are overly worn, they can jar the wheels, impact the brakes, which can cause you problems in emergencies. Ever had to stop quickly and your brakes not perform the way you’re used to? It could be a problem with your tires.

Especially on a front-wheel drive car, it uses gripping for traction. If the tires on the front are compromised, it can affect your car’s performance overall.

What happens during tire rotation?

Above all, tire rotation gives the mechanic a chance to inspect the tires and determine if there is a potential problem. This stops issues in their tracks. It also allows them to look at a variety of conditions, from proper inflation to how they are impacting the drivetrain. They also check tire safety, looking for things like overinflation, blistering, or cupping on your tires.

In most cases, tire rotation involves moving the front tires to the rear, and the rear tires to the front. There are other possible patterns depending on what the professional finds, and according to your manufacturer’s guidelines.

What’s your next step?

When was the last time you had your tires rotated?

When was the last time you scheduled a maintenance visit with your local mechanic?

Regular inspections are the easiest way to keep your vehicle in good condition, create peak performance, and reduce the cost you’ll spend on repair bills when things go wrong.

It’s your early warning protection system.

Daily Driving Habits That Are Destroying Your Suspension

June 18, 2021 by Denver Express Car Care

Habits and resolutions are something we all work on from time to time. Studies consistently show that while we’re good at setting habit intentions, we’re not as good at making them stick. Up to 80 percent of people give up or fail within the first 30 days of implementing a new habit.

Driving habits are difficult to break. While the basic skills we learned from our parents or a driving instructor, most habits we pick up as we age. If cell phones weren’t a thing when you were learning, you picked up the habit as new technology was introduced. If you text and drive, for example, you’re increasing your risk of an accident.

But some habits go deeper and impact the way your car operates. Your driving habits can cause uneven wear on your tires, wear your breaks long before their stated lifespan, or even affect your fuel efficiency. Damage may start out small, but if you’re consistent with your driving habits, it may be destroying your suspension system.

You don’t have to drive slow, take the back roads, or avoid driving altogether to keep your vehicle in good working condition. By being conscious of hazards and practicing good driving, your car will remain in good condition for the life of your car.

Do you find any of these daily driving habits in your normal routine?

Driving too fast

The faster you drive, the more risk you take while on the road. You become a defensive driver, always responding quickly to what’s happening around you.

If you tailgate and drive too close to the car in front of you, for example, you’ll be in reactionary mode. If they tap their brakes, you’ll slam down on your brake pedal to adjust your driving to match the road conditions. This wears down many parts within the suspension system, including the brake pads, rotors, shocks and struts. It can wear out all parts within the braking system prematurely, put you more at risk while you drive, and cost you more money as you’ll have more repair bills over time.

Daily Driving Habits That Are Destroying Your Suspension

You’ll also risk overheating the brakes. Here in Colorado, that can be a real risk, especially if you drive in the mountains frequently. Keeping your foot on the brakes is never a good idea while descending from higher altitudes. It’s tough on the suspension system if you slam on the brakes.

Hitting speed bumps without slowing down

The dreaded speed bump. They may have been designed to slow you down, but instead, you look at them as an inconvenience in how you drive. Ignore them and hit them at your regular speed and they can do extensive damage to your suspension.

While they may be annoying, they are placed on the road for a purpose. They are designed to slow you down; in this case, it’s a good idea to follow the rules.

While it may seem to do little to your car the first time you hit one, or the tenth, the damage is cumulative. You can hit it multiple times without visible consequences, but one day, you’ll face a multitude of problems. Like a blown tire, a broken shock or strut, or even break an axle if it’s old and in bad shape. The suspension system is designed for smooth driving conditions. The harder you take the largest bumps and dips in the road, the more impact it will have on all 30,000 parts.

Slamming into parking space dividers

How fast do you drive as you park your car? Are you always in a hurry to get where you’re going? Do you use the parking space dividers as a checkpoint to bring you to a halt rather than as a guide to keep your car safe?

Those parking space dividers may be there as a guide to keep you within the lines of the parking space, but they are big enough to do severe damage to your suspension system.

As you move your car forward into the parking space, your tires, wheels, and entire suspension system are in forward rotation. If they bump into the parking space divider, it brings your entire vehicle to a sudden stop. That jolts the wheels, and forces the whole system into a direction it’s not prepared to go. Damage may be unnoticeable the first time. Over multiple times you will start to hear and feel the results.

Hitting curbs

Now that you’re aware of what hitting a parking space divider can do, let’s talk about curbs. Curbs are built as dividers to keep the road separate from walkways and private property. They are built at about the same height as parking space dividers, and can create extensive damage to your vehicle.

Instead of creating a sudden forward/stop motion, hitting a curb can bounce your car around like a bumper car. It may be going forward one moment, but in an instant it’s moving sideways and in all directions in a matter of seconds.

Or maybe you’re in an area where parallel parking is a mandatory part of living. You used the curbs as a telltale sign you’re close enough to the curb. Every time you hit it, it forces your suspension to adjust to a new direction instantly. It can knock your wheels out of alignment, damage your tires and wheels, and create havoc on the suspension system.

Avoid road debris

The more aware you are of driving conditions, the better your car will handle over time.

Colorado seems to be a constant landmine filled with potholes, rocks, miscellaneous debris that drops off cars and trucks, tire rubber, and more. If you’re not aware of what’s in the road in front of you, if you drive too closely to watch for things in the road, your chances of hitting it increase.

Spotting hazards gives you a chance to avoid the issues before you hit them. It also allows you to have more control, adjust slowly to issues rather than jerking the wheel, and preventing damage to your car over time.

Be aware. It’s one of the best ways to keep your car safe from anything standing in your way.

How are your driving habits?

If you choose to change and adjust the way you drive, remember, it’s not a race but a journey. Be aware of how you drive. Make conscious changes.

Your car will thank you.

What Happens If Your Car Experiences a Vacuum Leak

June 10, 2021 by Denver Express Car Care

One of the most frustrating things about owning a car is experiencing a problem and not knowing the cause. That’s when the questions begin.

Is it important?

Should you bring it into the shop immediately? Or can you push it, waiting for a better time?

Car repairs can be expensive. If you wait, it can cause the cost of the repair to escalate rapidly. Instead of replacing a hose, for example, you might end up replacing an entire system. And that can be a heavy hit to the pocketbook.

It can also be difficult to know exactly what’s going on inside your vehicle. The average car has over 30,000 parts. If one piece has a problem, how will you ever find it? It may be easy to see if a headlamp is burned out, but it can be a lot more difficult to determine if there’s a problem inside the engine.

Understanding a car vacuum leak

To better understand how a vacuum leak forms, it’s essential to know how a car engine works.

An engine is a large, powerful vacuum that draws air in to be able to produce the amount of energy needed to move your vehicle. It uses pistons moving up and down to create the vacuum, which draws air into the engine and creates combustion.

This air is carefully metered through computerized sensors that analyze how much fuel to take in for maximum efficiency and power. Thanks to modern technology, it’s a process that can be tweaked and controlled to ensure your car continues to operate smoothly as you drive.

Through wear and tear, problems can arise. Each make and model can be set up slightly differently, but a vacuum leak occurs anywhere between the engine and the airflow sensor. Unmetered airflow enters the system and causes actual airflow to be higher than what the sensor can measure. That allows the system to miscalculate the amount of fuel injected into the system, which means your engine will run lean. Too much air causes too little fuel. And you’ll notice the impact of this vacuum leak in the way your engine idles.

How do you know if your car has a vacuum leak?

The 30,000 parts that make your car operate are all interwoven together in a complex way. When something goes wrong, it’s designed to make you aware of a potentially escalating problem by giving off warning signs. A vacuum leak is often diagnosed in one of several ways:

A rough idle

This is perhaps one of the most common ways to diagnose a vacuum leak. Because the leak allows too much air into the system and not enough fuel, it immediately shows up in the way the engine operates. You’ll feel it in the way the engine runs, and hear it as it attempts to stay operational.

Engine hesitation

In addition to the rough idle, you’ll also have trouble with the way your vehicle operates as you drive it down the road. With too much air and not enough fuel in the system, as you press the accelerator, the vacuum pressure will be more noticeable. You’ll have an engine that hesitates or stumbles as it attempts to pick up speed and move forward.

Fuel economy and emissions problems

When there is a change in the air-fuel ratio, the engine will burn hotter than normal. This increases the generation of oxide emissions, such as nitrogen oxide and sulfur oxide. Even if it isn’t strong enough to trip the check engine light, it will still be detected if you run your vehicle through an emissions test. You’ll also notice a reduction in fuel economy as the overall system tries to compensate by adding more fuel to the process. The EVAP – evaporative emissions control system – also depends on the vacuum to work. When it doesn’t, it can throw off the system functionality, sending an emissions trouble code back into the system.

Check engine light

Depending on your vehicle, the vacuum leak will eventually be detected by the monitoring system and react by turning on the check engine light. The check engine light can mean a variety of things, which is why it’s imperative to bring your car in as quickly as possible to avoid damage to any part of the engine system.

Engine damage

If you catch a vacuum leak early, you can minimize damage and fix the problem easily. The more the vacuum leak is allowed to continue, the more extensive the potential damage. Driving with a vacuum leak elevates temperatures within the engine compartment by running on a lean air-fuel ratio. This mixture over time can damage pistons and bearings, and can move to other parts within the engine, such as the catalytic converter.

Over time, damage can move more extensively underneath the hood. If you leave a vacuum leak unchecked, the situation will worsen over time. Depending on where the vacuum leak is and what type of car you drive, you can experience many other problems. With some vehicles, it may impact the engine and stall it as you park. For others, it can reduce braking power, meaning your car will be harder to stop.

The faster you solve the problem, the less likely it will affect other parts, putting you further at risk.

Identifying a vacuum leak

If you do a quick search online, you’ll discover several ways you can test the system to see if your car is experiencing a vacuum leak. Some take more working knowledge than others. If you aren’t familiar with how a car operates, your best course of action is to bring it in and let one of our skilled mechanics take a look. We can find the root of the problem, fix it, and have you back on the road in no time.

A visual check can alert you to potential problems with hoses and tubes. If they become stiff and brittle, they can easily crack or break under pressure.

A water check is a simple way to detect where the vacuum leak is. Spray a bottle of water where the vacuum leak is thought to be. A vacuum leak will suck in moisture and temporarily seal the leak.

Once you find the leak, fix it at the source. Keep in mind that the fix isn’t always straightforward. Hoses and sensors can be easy to find and change out. But if the problem goes deeper, such as a faulty intake manifold, it can be more time-consuming and costly, especially if you don’t fix it right the first time.

Think you have a problem under the hood? Is a vacuum leak impacting your drive? Bring your car in today. We’ll have you back on the road in no time.
