Get Your Car’s Air Conditioner Ready For Summer

May 10, 2021 by Denver Express Car Care

The temperatures are starting to climb. Fifties. Sixties. Seventies. Before we know it, we’ll be breaking records once again.

Here across the Front Range, those lazy summer afternoons are often a little difficult to enjoy outside. The intense sun beating down makes you hot just thinking about it.

Now think about your car. It’s there, sitting out in the blazing sun for hours at a time.

According to a San Jose University study, the temperature in the interior of your car can rapidly increase. On a one-hundred-degree day, the temperatures can climb to one-hundred-forty-five or more in just over an hour.

Cracking a window does little good. That same study shows it only allows a little air to circulate, but does almost nothing to bring down the temperatures on the inside.

Now imagine climbing in.

Hot!

As you turn on your engine, you want your air conditioner to work as quickly as possible. Will it? Or will it sputter and stop, barely providing you with any relief?

Before this scenario becomes a daily occurrence, take control now and get your car’s air conditioner ready for summer.

Get Your Car’s Air Conditioner Ready For Summer A car’s cooling system is an intricate part within your vehicle. Without it, your car wouldn’t operate as it should.

The cooling system includes many different parts, including the radiator, coolant, hoses, heater core, and water pump. With just a few simple steps now, you can ensure the entire system is working well, and will keep you cool all summer long.

Where do you start?

Listen

If you’re familiar with the way your car sounds, you’ll be more aware when a system starts acting up. Now, before the heat hits us with full force, turn your air conditioner on and listen. Does it make a sound as it turns on, or begins to operate? It should never be a loud process. It should be a hum in the background. If you hear banging, rattling, or anything else out of the ordinary, there may be something wrong somewhere in the air conditioning system.

Sniff

Air conditioned air always has a slightly different smell than the great outdoors. But it should never be overwhelming and distinctly noticeable. Turn the air conditioner on and sniff. Do you notice a strong, musty, or unpleasant smell? If dust, residue, or even mold or mildew built up inside the system, it can produce a scent reminiscent of a dusty attic. This not only is an indication of something wrong with your air conditioner, but it can also trigger allergies and asthma symptoms.

Look

When was the last time you popped the hood? Refrigerant sits in a container inside the engine compartment. A sight glass is fitted in the liquid line for quick reference. You can observe the refrigerant running through the system, which should look clear. If it’s milky or bubbly, it means water or air has penetrated the system and it’s time for a mechanic to replace it.

Feel

If an air conditioner is operating correctly, it should be able to bring the inside temperature down fifty degrees from the outside temperature. Of course, rarely will you have a desire for this extreme swing – moving from 100 to 50 isn’t what most of us consider comfortable. Still, your air conditioner should be powerful enough to handle the process. You can check it by turning your air conditioner on full blast, and leaving a thermometer inside the vehicle compartment. If there’s any problem with this test – especially if it’s not even close – it could be a sign something is wrong with the air conditioner.

What could be the problem?

If you’ve worked your way through the senses tests from above, and have a feeling something might be wrong with your vehicle’s air conditioner, it might be one of several things.

Radiator – when it comes to the health of your vehicle, the radiator plays an important part. The radiator’s job is to ensure car coolant (also known as antifreeze) passes through the engine to cool the system down. If it’s not working correctly, it can allow the engine to overheat, and the entire system to fail.

Water pump – it’s the water pump’s job to ensure coolant moves freely from the radiator to the engine. If the water pump slows or comes to a stop, this process will slow or cease, allowing the engine to overheat. When the water pump is working correctly, it’s designed to keep the cooling system at the proper temperature, no matter how much demand is placed on the system. If you notice coolant leads, or if rust starts forming around the engine compartment, it may be a sign of a faulty water pump.

Belts and hoses – while a lot of talk is about the main parts of the coolant system – radiator, water pump – there are a lot of pieces in the system to ensure it works properly. If one belt comes loose, if a hose cracks, the entire system starts to fail. The serpentine belt is the main belt that drives the cooling system. It circulates the water pump to keep your car cool and operating well. Even a tiny crack can throw this process off, and start degrading the system.

Heater core – the cooling system actually operates using the heater core within the vehicle. Signs your heater core may be the source of the problem include coolant leaks under the dashboard, an engine that runs hot, or you can smell coolant while sitting inside your car.

Coolant – while you don’t have to top off coolant in the same manner as motor oil or windshield washer fluid, it can decrease over time. You can check the antifreeze holding tank and ensure it’s filled to the full line. If not, it’s time to top it off. Be aware that coolant comes in different formulas, and some need to be mixed with water before adding to your vehicle. Get this wrong, and your problems will quickly escalate. That’s why it’s better to allow a mechanic to fully check your system, and repair only when problems are discovered.

Is your vehicle’s air conditioner ready for summer driving? Before the temperature climbs and stays high for the summer, bring your car in for a full maintenance visit today. We’ll ensure your cooling system is ready for no matter what the Colorado summer will dish out.

Used Car Inspection

May 10, 2021 by Denver Express Car Care

It’s natural for Denver drivers to be a little anxious when they buy a used car in the Denver area; it’s natural to worry that it has something wrong with it or that it hasn’t been well maintained. If it’s possible, bring the vehicle in for a used car inspection at Express Car Care. Your friendly and knowledgeable service adviser can tell you if there are current or emerging problems in the used car that you’re interested in purchasing. The peace of mind is well worth the price of the inspection service.

It’s also important for Denver drivers to get on track with the maintenance schedule and stay on track. If you don’t have maintenance records for the used car assume the worst and get started right away with an oil change at Express Car Care. The inspection by Express Car Care that comes with a full service oil change will reveal any basic problems. Be sure to bring up any specific concerns you might have with your service adviser. A more intense inspection can find hidden problems like body damage and sealer in A/C units which can be major expenses down the road.

Purchasing a Carfax report may let you know if the vehicle’s been in a major accident and give you a title history. You can find out if that ’71 Barracuda really was owned by a little old lady who only drove it to church on Sundays here in Denver.

If you’ve bought well, there’s no reason to believe that with proper maintenance your “new” used car won’t last a long, long time.

Give us a call and let us help.

Simple Answers: Improve Fuel Economy

April 26, 2021 by Denver Express Car Care

Question: What can I do to improve my fuel economy?

Simple Answer: There are a few things that you can do – some of them are easy and some take a little more effort. One of the first things you should do is make sure your tires are properly inflated. On the inside of the driver’s door or door jamb is a plate that says the correct tire pressure. Careful – there might be a different pressure recommendation for the front tires and rear tires. Check them at least once a month.

Carrying extra weight in the vehicle will hurt your fuel economy. Leave any unnecessary stuff at home. Do we even need to mention driving fast and jackrabbit starts? When you gently accelerate and plan your stops so that you can ease into them a bit, this way of driving will make a big difference in improving your fuel economy.

Now there are several maintenance items that improve fuel economy. Lubricants should be replaced on schedule – dirty oil, transmission fluid and differential fluid cause more friction and drag which hurt fuel economy. A big one is having a fuel system cleaning done if needed. A dirty fuel system can really reduce engine efficiency and increase fuel consumption.

And if your check engine light is on, take your vehicle in for a diagnosis. Some conditions that trigger the light can really hurt your fuel economy. Getting the necessary work done to correct the fault will help your engine run better and may bump up your mileage.

Also be on the alert for so called miracle cures. There are a lot of products out there that claim to increase fuel economy. Research them before you spend your money. And as always your service adviser can give you more ideas on how to improve your fuel economy. At this time when fuel prices are high and getting higher daily, we need to do all we can to improve fuel economy.

Brake Check Checklist To Ensure Your Passengers Safety

April 25, 2021 by Denver Express Car Care

When it comes to vehicle safety, there are many tasks you shouldn’t ignore. Motor oil is important; experts suggest replacing it about every 3,000 miles. If your tires wear out, not only will they provide a very bumpy ride, but they may also suffer a blowout, putting you and your passengers at risk.

But few would argue at the top of the safety list is your car braking system. The head of the Car Care Council said it best when he stated, “If brake service is neglected, you’re gambling with your safety, and the safety of your passengers and other drivers.”

For all those reasons and more, it’s important to keep a brake check checklist handy, and refer to it from time to time to ensure your car’s braking system is operating the way it should. It’s the best way to keep you and those around you safe and secure.

A good brake check inspection will allow you to recognize when things go wrong, as well as allow you to take action before bigger problems arise. If you have an older car and you haven’t paid much attention to the brakes lately, do this now.

Step 1: Schedule a brake inspection

A car’s brake system is made up of a variety of different components.

The brake master cylinder pushes hydraulic fluid into the brake lines. Most master cylinders have two components for safety reasons, one section to control the front brakes, the other for the rear brake. It works by controlling the amount of hydraulic fluid released in order to maintain the pressure used to slow down the vehicle.

The brake rotor (or brake drum on older cars) spins while the car is operating. The brake pad and caliper push against the brake rotor to cause friction necessary to slow down and stop the vehicle.

In a disc brake system, the brake pad and caliper are used to control the speed by pressing up against a spinning brake disc. Brake calipers provide a clamping force that pushes the brake pad against the rotor.

The alternative to this is a brake shoe that is used for slowing and stopping drum brakes. The brake shoe rubs against the interior of the drum brake to control speed.

The brake pedal is the connector to give you control of how much pressure is applied within the braking system.

Many vehicles today are equipped with an anti-lock braking system (ABS). Each wheel has a sensor that detects how fast each wheel is spinning. If your wheels lock and one or more wheel spins at different speeds, the ABS module turns on to help you safely control and stop your car. This is run by an ABS module that programs the speeds and keeps the system working.
Brakes lines move brake fluid throughout the system to allow ease when you tap on the brakes.

While these are the main components of the braking system, there are many more parts that go into making up each individual component. If any of these parts wear down, break, or leak, it can put your braking system in jeopardy.

When you schedule a brake inspection, a mechanic will look at the entire braking system thoroughly. They move through the entire process, ensuring parts are in good condition, fluid is at the right levels, and every piece is working as it should. If you’re heading out on a road trip, this is an important step before you leave to give you added insurance your car is safe for the road.

Step 2: Never ignore warning signs

As a part of your brake check checklist, you should become aware of how your vehicle runs when it’s working at its best. How does it act? How does it sound?

Being aware of what your car sounds like in good working condition will help you pick up on the signs when something goes bad.

Do you hear a squealing, squeaking, or grinding noise? The brake pads are built with an internal indicator to create sound when they reach the end of their lifespan. They provide you with plenty of warnings to schedule an appointment and get your car in for servicing. A grinding noise might also mean dirt or debris has made its way into the brake line, and is causing havoc somewhere within the system. Bringing it in for servicing will allow a mechanic to thoroughly inspect the brakes and make corrections as needed.

Do you feel a vibration in the steering wheel? It could be uneven rotors. As the brake pads apply pressure to each of the four rotors, unevenness will send shockwaves through the system, and present itself as wobbling or a vibration.

Do you notice a spongy or soft brake? Over time, it can take more pressure applied to the brake pedal to slow and stop your vehicle. This could be a leak in the brake lines, or a problem with the master cylinder. This is also a sign you should schedule servicing as quickly as possible.

Do you smell something burning? If your brakes overheat as you use them, they have a sharp chemical smell you can’t miss. If your brakes get too hot, it can cause brake failure, meaning you’ll be driving without braking assistance. It’s important to pull over to safety immediately, and get your brake system checked out.

Step 3: Use your brakes correctly

This sounds almost obvious, but some drivers consistently put too much pressure on their vehicle’s braking system.

Speed is the enemy. If you drive too fast, follow too closely, and often find yourself slamming on the brakes, you’re putting too much pressure on the brake system. You’ll replace brake pads and other parts more frequently than if you slow down and drive less aggressively.

Coast when you can. Don’t hurry up just to stop again. And avoid being a two-footed driver. Having constant pressure on the brake pedal means your brake pads wear out that much faster.

If the brake warning light illuminates, don’t ignore it. Schedule your appointment with a mechanic today.

Step 4: Find a mechanic you can trust

While a trip to the service station often ends with you spending money on car repair, if you get to know your local mechanic, you can work in partnership to keep your vehicle safe.

If you have any questions about how to extend the life of your brake system, and how to get the most out of the parts you install, we’re here to provide the answers. Just call.

9 Car Noises You Should Never Ignore

April 21, 2021 by Denver Express Car Care

What’s that sound?

Is that normal?

Before you ignore it altogether, turn up the radio as you drive, take a moment to figure out exactly where the noise is coming from. The difference could be a simple fix versus a major auto repair.

The average vehicle on the road today has around 30,000 parts. If a screw falls out, if a belt loosens, if a part wears out, it’s going to create an odd sound. The only question for you is: does it matter? Should you disregard the sound? Or are there car noises you should never ignore?

To help you distinguish between the two, we’ve put together a list of the most common sounds, what they mean, and give you a better understanding of which noises you should pay attention to.

Squeaking

When you get into your vehicle, you expect certain things to happen. Step on the brake pedal and you assume you’ll slow down without a hitch. When you tap, do you hear a squeaking sound? That’s the first indicator there’s a problem with your brakes. Brake pads are designed in such a way that they provide warning sounds long before they’ve reached their lifespan. As the brake material wears, it gets closer to the wear line built in. When this touches the brake rotor, it makes a squeaking noise. You can’t miss it. You should never ignore it. While you do have some time before the brake pad completely wears down, the noise will be annoying enough to make you bring it in and repair it.

Knocking

If you hear a knocking noise from the engine, it could mean your engine is low on oil. Low oil isn’t something to avoid as it can cause serious issues with your entire engine compartment. As an engine operates without proper fluid levels, the various components start failing. If the rod bearings fail, for instance, you might be replacing your engine soon. When you hear the noise, take note of where it’s coming from and how frequently you hear it. Bring it in as soon as possible to stop the problem from increasing.

Rattling

Rattling noises can drive you crazy. You press on various parts of your car, trying to figure out where it’s coming from. If you’ve pinpointed it’s coming from the front wheels, and you drive a front-wheel drive car, does it happen when you accelerate or make a hard turn? If water seeps into the joints that allow your tires to turn, they can rot. It makes a distinctive sound under certain circumstances. Of course, that’s not the only part that can rattle. With 30,000 parts, if any one of them comes loose, it can allow two or more components to come together and create an annoying sound. Maybe your muffler is loose. Or you have a problem with brake connections. Regular maintenance on your vehicle will ensure everything is properly connected and working as designed.

Howling

Does a howling noise seem to come from the back of your vehicle as you drive? Do you operate a rear-wheel drive car? It may be a problem with your read differential. Worn parts may include bad bearings, worn gears, or a pinion problem that causes a distinctive sound as you drive under different conditions. Accelerating and decelerating may exacerbate the noise.

Clicking

Some noises are more noticeable at certain speeds. At lower speeds, as your wheels turn and move, you may hear a clicking sound that sounds similar to when you drive over train tracks. This could be a problem with your drive axles. Velocity joints control the vertical movement of your car, send power into the wheels, and control your ability to steer. If the sound worsens, it may impact your ability to control your vehicle.

Hissing

You can’t miss a hissing sound. It sounds like air is being released somewhere underneath the hood. If it’s coming from your engine, you may have a leak in one of the many connective parts, such as a vacuum line, or a tube in the cooling system. If any of these parts aren’t working properly, quick repair is necessary to keep your engine working well. Leaks may start out small, impacting something as small as the way your dashboard works. But it can quickly escalate to your engine’s performance. If you have a question about something within the engine compartment, act quickly to avoid larger repair bills.

Grinding

When you hear a grinding noise, that usually indicates metal on metal, rubbing against one another. That means joints and lubrication have deteriorated enough for the parts to be connecting and wearing away. Notice where the noise is coming from for a better indication of what system it’s impacting. Under the hood, for example, could indicate a problem with the water pump, or a drive belt that’s failing.

Tire noise

One of the most difficult noises to recognize are the noises that change over time. You get used to the way they sound because the change is gradual. Tires will last thousands of miles. But if you have a problem with the way a tire connects with the road, one tire may wear out faster than the rest. That can also cause varying noises to come from different wheels. Pay attention to how they sound. Changes in noise level could mean a problem with alignment or suspension, which can impact the smoothness of your drive. It can also impact gas mileage over time, and eventually wear down different systems in your vehicle.

Whining

Most of us drive with an automatic transmission these days. As you move it into gear, it should operate smoothly with little noise. If you hear a clunking or banging as you move gears, that’s an indicator of a problem within the transmission system. As you’re driving, it shouldn’t produce a whining noise.

Have you started to hear strange noises as your car ages? Have some of them gone from bad to worse? Don’t wait. Waiting can also cause your repair bill to escalate. There are certain car noises you should never ignore. If you hear any of the above, schedule an appointment with our mechanics today.

A Guide To Your Car’s Air Conditioner Condenser Before The Summer Heat Hits

April 17, 2021 by Denver Express Car Care

Springtime in the Rockies. It can be in the 70s one moment, and a blizzard the next. You may find yourself turning on your car’s air conditioner in the afternoon underneath the blazing sun, followed by the heater as the sun dips behind the mountains.

Is your car’s air conditioner condenser up for the job? Is it ready and waiting for the hottest days of the year?

How your car’s air conditioning system works

While almost every car purchased today comes with air conditioning as standard equipment, that wasn’t always the case. Air conditioning grew in popularity in the 1970s, and it quickly became the standard in auto production.

The air conditioning system in your car today works similarly to how it was first put into production back in the 1930s. Air conditioners are built with three main parts: the compressor, the condenser, and the evaporator.

The three work together to push refrigerant through a high pressure/low pressure closed-loop system. As the refrigerant moves through the loop, it changes from gas to liquid, and back again.

The compressor takes in low pressure refrigerant gas and compresses it to a high pressure, high temperature gas. It then pumps this gas into the condenser.

The condenser dissipates the heat outward, and turns the high pressure gas into a high pressure liquid. It removes any water formed during this process as it moves through a dryer system before being pumped out to the thermal expansion valve.

It’s there that this high pressure liquid is allowed to expand and become a low pressure liquid that enters the loop system and into the evaporator located in your car’s interior. The refrigerant moves from liquid to gas form once again as the evaporator takes in the heat from the inside of your car.

As this occurs, a fan blows over the compressor, creating the cooled air you feel through your vents. As the gas enters the compressor, it continues through the closed-loop system, and the process starts all over again.

What are the symptoms of a bad AC condenser?

A vehicle’s air conditioning system depends on a steady flow of refrigerant moving through it. This is what it needs to produce cooled air, and send that air out through the ventilation system.

The only way refrigerant can do its job is if the air conditioner condenser is working. But like other parts on your vehicle, an AC compressor can fail. Luckily, it doesn’t happen all at once. It provides you with warning signs so you can take action before it stops working altogether.

Noises – You can’t miss the noises a compressor might make as it develops problems. The compressor relies on a closed-loop system to operate, which is held together by a series of sealed bearings and other components. As these wear, break, or are damaged in any way, it becomes more difficult for the compressor to operate properly. Whether it’s a squeak, a squeal, or a bang, if you notice a noise as you turn your air conditioning system on, it’s time for an inspection.

Hot air from the vents – On a hot day, if you turn on the air conditioner the moment you enter the car, the only thing you’ll feel coming from the vents is hot air. If that hot air continues, it’s a clear indicator of a problem with the AC compressor. If refrigerant can’t circulate throughout the air conditioning system, it won’t be able to create the cooled air you want. This usually isn’t an all-or-nothing process. Gradually, the cool air will warm, and you’ll start to notice your air conditioner doesn’t put out as much cooled air as it used to. Eventually, it will stop altogether.

Leaks – The AC compressor is made up of a series of components to keep it working well. Over time, if those internal bearings and connections fail, the pressurized refrigerant can start to leak. Refrigerant won’t show up as a puddle underneath your car, the way other fluids might appear. Instead, refrigerant leaks appear as a thin, greasy substance that appears around the compressor itself, or small pools if it’s really bad underneath your vehicle. Refrigerant is bad for the environment, so it’s imperative that you fix the problem quickly to avoid further release into the atmosphere.

Are there ways to maintain the air conditioning system?

Luckily, your AC compressor isn’t something most car owners replace. If your car is well cared for, your compressor can last for tens of thousands of miles.

But that doesn’t mean you should take a back seat, and wait until warning signs occur. Like other systems inside your vehicle, there are general maintenance items you can occasionally do to ensure the air conditioning system continues to work well.

Your vehicle’s cabin has an air filter, which is positioned between the air conditioning system under the hood and the vents that blow air inside your car. Check this regularly, and replace it if it’s clogged or blackened with debris.

Don’t forget to clean your entire vehicle, inside and out. Running it through an occasional car wash is a great way to ensure the outside looks great. But don’t forget that salt, mag-chloride, and other contaminants can spray up into the engine compartment as you drive on Colorado roads throughout the year. The condenser sits in front of the radiator. A simple flow of water from a garden hose can clean the grille, which allows the airflow needed for the air conditioner to work.

An occasional inspection should also be made, especially if you’re heading out on a road trip. Pull it into our service station and let us evaluate your entire vehicle. We often catch small repair items that, if left unchecked, could quickly escalate as you head out on the road. It’s one of the easiest forms of preventing, ensuring your car stays in great shape for years to come.

When was the last time you pulled your vehicle in for an inspection?

Why Car Repair Shop Reviews Matter

April 13, 2021 by Denver Express Car Care

When were you last in a situation where your car had a problem, and you didn’t know where to go?

We’ve all been in that situation before. Maybe you’re new to town. Or maybe you’ve purchased a new home in a new neighborhood and aren’t familiar with the local shops.

You want to do business with a local, but where should you go?

Typically, there are three ways to find a new car repair shop.

1. Drive by. Every day as you’re out running errands, you notice the repair shops in your community. Which one should you trust?

2. Mailers and flyers. Of course, you can always rely on marketing. Homeowners are bombarded with flyers in their mailboxes offering coupons for different services. Does one of them seem to be a good deal, and applies to what’s wrong with your vehicle?

3. Referrals. Arguably, this is one of the best ways to discover new shops. If your neighbor or friend trusts a place, maybe you can too.

Still, we’ve all heard horror stories about taking your vehicle in for service, only to have the mechanic come out and tell you there’s a major complication with your car. Do you trust the advice? Do you sink hundreds – thousands – of dollars into your vehicle?

Do you trust that they are telling you the truth?

Two types of car repair shops, which is right for you?

As you’re running errands, you’ve probably come across two separate types of car repair shops in your neighborhood: national brands, and locally owned shops.

The national brands are part of a corporate conglomerate with shops all over the country. Their names are recognizable, and part of that is to gain your trust. If you visit one in your local city, you can go to one in another town and expect similar service. Of course, that’s not always the case.

Locally owned shops are also known as “mom and pop” shops. They were started by a local member of the community, and operate as a family operation. You’ll typically talk with the owner and get to know them over time.

According to a survey by Consumer Reports, independent mechanics provide a more satisfying experience. They surveyed over 40,000 consumers and asked them about their recent repair experiences. One mechanic they interviewed said it best:

“If you keep your car for many years, find a local, independent garage you can trust, and then build a relationship by giving them repeat business. If you stay loyal, they’re bound to treat you right, which can be advantageous when it comes to those really expensive jobs.”

With most large corporations, they operate to maximize profits. They set prices and stick with schedules to ensure maximum revenue. The people you meet when you bring your vehicle in are employees. And as employees, they come and go based on their goals and desires.

Local car repair shops are locally owned and operated, often bringing in family and friends who stick around. You’ll see the same friendly faces every time you bring your vehicle in.

How do you find a car repair place you can trust?

As mentioned before, you can find local service shops in a variety of ways. As you narrow down your focus, that’s when you should head online. While you might receive one or two reviews from your neighbors, online, you can gain a wealth of information with only a few clicks. Whether you use social media like Facebook, or review sites like Angie’s, you’ll start to see patterns emerge.

Car repair shop reviews help you monitor quality – If a business is around for any length of time, chances are you’ll find a number of reviews online. People realize how important this is, and they are highly motivated to leave their own. Don’t read one or two and finalize your decision. Instead, take some time to get a consensus about how people feel about the local shop. Do they like the people? Do they like the service? Do they have any trouble with the mechanics of the repair after they drive away? Online reviewers are honest about quality, and you can quickly build a better understanding of how well a shop is doing.

Car repair shop reviews build trust – One review might not be enough to lower your concerns, but how about ten, or twenty? Building reviews online should be a part of a local business’s goals. It’s a great way to tell other people in your community about the great resources you’ve been using for years. With reviews, you can also see the dates of when the item is posted. Does the service stay the same year after year? That can be a bonus for a local shop.

Car repair shop reviews can also show your customer service care – Let’s face it, all reviews aren’t going to be positive. This is also a chance for a car repair shop to show its true colors. How do they handle the situation? Do they ignore the review? Or do they take the time to answer the poster and face the problem head-on? Not every customer is going to gel with a business, and that’s okay. This is where it’s important to read reviews carefully, and go with the majority view. It will tell you everything.

Celebrate good reviews

There are many ways to celebrate good reviews. Increasingly, online review resources understand how difficult the process of finding quality repair shops can be, so they highlight service businesses that go above and beyond.

Here at Express Car Care, we take our reviews and ratings very seriously. We’ve recently been awarded the distinction of being a 2020 CARFAX Top-Rated Service Center, with an average rating of 4.9, and we couldn’t be happier!

Battery Cable Maintenance

April 12, 2021 by Denver Express Car Care

Chances are you’ve had the power go out in your neighborhood at some time, and you know how helpless that can make you feel. No lights, no microwave oven, no cold refrigerator, it’s like living in another century!

Well, your vehicle is also highly dependent on having power for it to run properly. This is why battery cable maintenance is so important. When your battery cables are failing, the power that needs to be transferred for your vehicle to run properly, isn’t being transferred.

Battery cables are essentially the wires that connect your vehicle to its battery. The positive cable supplies the power to the various components that use them and the negative grounds the system to the vehicle chassis. This setup allows you to have power throughout your vehicle.

When a battery cable fails, your vehicle may not start, your starter may turn over very slowly, or you may hear a clicking noise. And you may see your battery warning light go on. Just like a house with no power, a vehicle with no power needs to get reconnected to its power source in order to work the way it should.

It’s important to keep your battery cables clean and maintained. You may have noticed a greenish white substance building up on the battery terminals. This corrosion can start to move inside the battery cables. Corroded cables don’t conduct electricity well. Your Express Car Care technician can disconnect the cables, check them and clean the cable ends and the battery terminals. This preventative battery cable maintenance will help extend the life of your battery and your battery cables.

If you are noticing any signs that the power in your vehicle isn’t acting the way it usually does, head on over to Express Car Care and have one of our technicians check it out. More power to you!

When Should You Use Your Parking Brake

April 10, 2021 by Denver Express Car Care

Your car’s braking system is one of the most essential mechanisms built in for safety. Imagine driving down the mountain after a day of skiing without it. Even coming to a stop for a stoplight would be a harrowing experience if something were to go wrong.

While your front and rear brakes make up the most important part of the braking system, there’s a third brake that doesn’t get as much attention yet is equally important: the parking brake. The parking brake is connected to the rear brake system, and is used mainly as a failsafe if something were to happen to your brakes during your normal drive.

The parking brake is a secondary brake system that is designed to be independent of the front and rear brakes. This is your safety feature. You’ll find the control for your parking brake in one of four places:

Center console – it’s a lever located between the two front seats

If you drive a manual transmission, you may be used to using a parking brake to keep your car from rolling. But that doesn’t make a parking brake on an automatic transmission any less important. In truth, everyone should be familiar with the uses of a parking brake, and utilize it to make your driving experience safer.

How a parking brake works

Your vehicle’s brakes are designed to bring your car to a stop. The more pressure you apply to the brake pedal, the more tension is transferred from the brake pad to the wheel, slowing your car until it eventually stops.

When you engage the parking brake, discs inside your rear wheel squeeze up against the inner part of the wheel in much the same way. This action slows the wheel, eventually stopping it and keeping it from rolling away.

While parking brakes work in a slightly different manner from vehicle to vehicle, to engage the parking brake, fully engage the rear brake system by pressing down on the brake pedal. Only then should you pull the lever or press the button for the parking brake system. Once the parking brake is in place, shift your car into park. Then release the brake pedal. This allows the hydraulic system to activate and do its work without putting added stress on the transmission.

Why your vehicle has a parking brake

In everyday situations, you might be tempted to only utilize your vehicle’s braking system. When you place your vehicle in park, a parking pawl is pushed into one of the grooves of the transmission gear to keep it from moving. A parking pawl is nothing more than a hammer-shaped pin that drops into place. While it might be enough force in everyday situations, it can weaken over time, especially if you’re on steep inclines or hills. One small pin stopping a several ton vehicle will only work for so long.

If you don’t use your parking brake regularly, this parking pawl weakens over time. That can impact your transmission system, or cause accidents as your vehicle rolls away. That can lead to expensive repairs.

Get in the practice of using your parking brake

Even if you infrequently drive, even if you park in relatively flat areas across the Front Range, your vehicle can still be at risk. If you’re putting your car in park, it’s a good idea to engage the parking brake too.

We advise using a parking brake no matter where you park your vehicle, but especially as your risk level increases.

Are you parallel parking on a hill? Engage your parking brake.

Are you filling up your vehicle at a gas station? Engage your parking brake.

Will you be leaving your car in a parking garage for hours at a time while you head into the office? Engage your parking brake.

It’s better to be safe than sorry. And a parking brake gives you added insurance to ensure your vehicle stays safe.

In many cases, people refer to a parking brake as an emergency brake. That title may be a bit misleading, making you think you only need it in emergency situations. The parking brake not only keeps your vehicle from moving, but it also saves your transmission from wear and tear. And that can save on repair bills down the road.

Using a parking brake in an emergency

Your car’s braking system is a complex mechanical system. Over time, it can fail, and that could be catastrophic depending on where it happens. That’s where the emergency brake comes into play. If you’ve ever referred to the parking brake as an emergency brake, this is why.

In the case of brake failure, you have seconds to react. A natural reaction is to stomp on the parking brake pedal, or pull up on the parking brake lever as hard as possible. Resist that urge. That will send your car into a tailspin, and possibly put you in even more danger.

Instead, slowly engage the emergency brake as your car comes to a stop. The parking brake is designed to hold your car in place, not stop it. As it engages, it slows your vehicle down until the point you can gain control.

Get a full brake inspection

If the concept of using your parking brake regularly is still new to you, put it into practice today. It can help your vehicle have a longer lifespan, as well as keep it safer over time.

Have a question about how well your brakes work? It’s time for a complete brake inspection. It’s the easiest way to determine how safe your entire braking system really is. By bringing it in, we can tell you how much wear is left on your brake pads, and give you tips on better driving and maintenance. If you pinpoint issues early, you’ll stay safer in the long run.

Is That a Radiator Leak?

April 7, 2021 by Denver Express Car Care

If you’re a careful driver, and do what you can to ensure your car has a long life, you may notice when liquid appears underneath your vehicle and wonder if everything is alright. Is it oil? Is it water? Is it something else?

It’s good to be aware every time you get into your car. Awareness can help you drive safely without having to worry about being stranded by the side of the road. But it still takes a careful eye to notice all the potential warning signs your car sends out.

What is a radiator?

A car’s engine produces a lot of heat during operation. To prevent the engine from overheating, your car pumps coolant through the engine to take in the heat and move it away from the engine block. Coolant takes heat into the radiator, which blows air across the liquid to cool it down, before exchanging the heat with the air outside your car. It’s like a mini air conditioner built exclusively to keep your engine cool and running at its best.

If the radiator doesn’t work at its best, it can cause your engine to overheat, impacting the drivability of your car.

If your vehicle overheats, a lot can go wrong internally. Various parts can be impacted, including the engine, thermostat, gaskets, and other components connected to the engine block. That’s why it’s important to recognize potential problems, and fix them before they allow bigger problems to occur.

Leading warning signs of radiator leaks

Radiator leaks rarely happen overnight. Instead, minor problems slowly develop as your car ages. Here’s what to watch for.

Drop in coolant levels, rise in temperature – do you keep an eye on your temperature gauge? You should. You’ll notice it remains relatively static as you drive. Coolant levels rise and fall based on engine temperature. It adjusts to keep your engine at a constant level. A quick drop in coolant levels can be a good indicator there is a leak somewhere in the system. If you think there may be a leak, fill the reservoir back up with coolant, and recheck it after a few days of normal driving. Watch the temperature gauge during this time. Does it lose fluid? If so, bring your car in for inspection as quickly as you can.

Visible fluid leaks – if you’ve ever experienced an engine misfire, it’s easily recognizable. When you turn the key or press the button, the engine fumbles for a bit as it struggles to catch and stay running. The more frequent this is, the bigger the problem. A spark plug misfiring releases a variety of problems into the overall process of starting and operating your vehicle. It can release too much raw fuel into the exhaust, which can cause internal temperatures to rise. This restriction can lead to problems throughout the system, including the converter substrate, which may further restrict the exhaust. Never ignore the warning sign of an engine that doesn’t turn over quickly every time you turn the key.

Visible damage to hoses and parts – when is the last time you popped the hood and took a look underneath? You don’t need a class in auto mechanics to notice when something is wrong. Rust or discoloration around your radiator or surrounding the engine block may be a sign of a coolant leak. Radiator hoses and clamps will also wear down over time. They should be washed and checked regularly to ensure they are running smoothly without leaks.

Regular inspections – when you work with an auto mechanic regularly, they can notice items that may otherwise go undetected until bigger problems arise. Think of an auto inspection as your vehicle’s yearly checkup. It’s a way to test each system, look at the major parts, and determine how much life is left in each system. A mechanic will notice what systems have potential problems, and what parts should be replaced to avoid problems on the road. They can also give you a clear indication of how much time you have left in different systems. This can allow you to plan for further repair work when you have the time. This is especially important if you’re planning a road trip in the near future.

Is a radiator flush necessary?

Coolant’s job is to push fluid through the system, keeping your engine cool and running properly. Over time, that coolant can begin to break down. That’s when it no longer can serve its purpose.

Over time, dirt and debris can build up inside. That’s when a coolant flush is necessary, to flush out any corrosive debris, rust, or other contaminants that have built up inside.

A technician will take several gallons of radiator cleaner and water, and flush it through the cooling system. This gets both old antifreeze and other contaminants out of the system. If this isn’t done the right way, it can break loose debris and leave it in the system, which can quickly damage major other components and lead to problems with the engine overheating.

How do you know it’s time for a radiator flush? A technician will usually look for several things.

Orange or green fluid is leaking
The radiator is corroded, dirty, or rusty
You’ve noticed steam coming from underneath the hood
Your car smells like hot maple syrup under the hood

If you’re considering this as a DIY project, keep in mind that you have to clean the surrounding area thoroughly. Antifreeze is a sweet smelling liquid that attracts both animals and children. Your space should be cleaned entirely of both old and new coolant to ensure you don’t put anyone around you in danger. That’s the upside of having a mechanic perform this task for you. They know how to complete the job efficiently, as well as dispose of all fluids properly after the job is done.

You have a choice. If you pay attention to the way your car operates, you’ll notice slight changes that can have a big impact. You’ll check coolant levels, and fix leaks before they grow. You’ll flush your radiator to keep it operating at its best. This will allow you to stop problems before they arise; a radiator flush is much less costly than replacing the entire radiator. Or worse, the entire engine block.
