What Happens If You Don’t Change Your Car’s Motor Oil

August 14, 2020 by Denver Express Car Care

One of the very basic items to keep your vehicle running is motor oil. Outside of gasoline, it’s the number one thing you’ll change out on a routine basis.

But as you buy another can, or drive into your local service station for a motor oil change, have you ever wondered what would happen if you skipped it altogether? What if you waited a few months? What if you didn’t follow the guidelines? How bad could it be?

Many of the guidelines state that a car’s motor oil should be changed every 3,000 miles or 3 months, whichever comes first. If you check your owner’s manual, depending on the vehicle you drive, it may push that up to 5,000 or more.

What should you believe?

What motor oil does

Before we get into how frequently you should change it out, let’s talk for a moment about what it does.

Motor oil has one purpose: it’s designed to keep your car running smoothly. It’s designed to lubricate the engine and help carry heat away from the engine compartment. As the motor oil circulates throughout the system, it continuously lubricates the thousands of parts that come together and make your vehicle operational. And at the same time, it helps dissipate heat, carrying it away from where it can do the most harm.

That makes motor oil pretty important, right?

Think of motor oil as the lifeblood of your vehicle. If it doesn’t have a high quality supply running throughout the system, it can function at peak performance. And that means things will start to wear down over time.

Fresh, clean motor oil will keep your car in its best possible condition.

If it degrades, your car will start to wear down.

What really happens without fresh motor oil?

Glad you asked. It’s important to keep in mind that every car reacts in its own unique way. Your car won’t suddenly wear out without new motor oil at 3,001 miles. It’s more of a gradual process.

As motor oil works and moves throughout the system, it picks up all kinds of dirt and debris. If it’s working well, it can push this debris away from the moving parts and into an oil filter. But if you don’t replace the filter (it’s part of a regular oil change), the filter will eventually become too clogged to do its job. That means whatever the motor oil pushes in, it bypasses it and leaves it within the system.

That’s when engine parts start to wear down. Instead of fresh, clean motor oil, dirty fluid is circulating throughout the system. And it might not be doing a very good job. It can be abrasive, causing parts to rub together in wrong ways. It might not keep each part properly lubricated.

Motor oil isn’t just oil. Instead, it’s a combination of oil and additives designed to keep your car running at its best. It has things like detergents, dispersants, rust-fighters and friction reducers all working together to provide your vehicle with what it needs to thrive. You know when you’re washing dishes and the soap bubbles eventually dissipate because of all the grime that makes its way into your sink? That happens to motor oil too. The additives can’t work the way they did when you first added motor oil to the system, not once the system is compromised.

So the oil gets thicker, dirtier, and loses the ability to do what it was designed to do – keep heat out of the engine compartment. Heat builds. Parts warp. Damage starts to occur. And your car might not drive quite the way it did before.

But you still might notice anything. You might continue driving.

This turns oil into sludge. The volume of dirt and grime becomes too much, and it can’t process it at all. It barely moves, loses most of its lubricating qualities, and brings no relief to your vehicle’s parts.

If you leave it this way for too long, the engine will seize, and stop working altogether.

A high quality motor oil change is something you’ll barely notice in your monthly budget. We guarantee you’ll feel the pain of replacing a seized engine. It can cause thousands of dollars to bring your car back into working condition.

What else happens along the way?

Now that you know what happens within the engine compartment itself, let’s talk about a few other things you should know.

Did you buy a new or used car with a warranty? The warranty is only good if you follow the rules. And if you read the fine print on the warranty itself, you’ll find that it states you have to service your vehicle according to a schedule. If you don’t service it according to factory guidelines, the warranty will be null and void. Yes, that means you should keep track of every motor oil change you do. For that matter, you should keep a record book of every maintenance item you do, just to be able to refer back and determine all that you’ve done to your vehicle over the years. It can also be something that gives you an edge when trying to sell it down the road.

And long before you face a seized engine, you’ll also find your vehicle shows poor engine performance. When detergents and lubricants aren’t working correctly, you’ll hear and feel your engine sputtering. It can materialize as poorer gas mileage too.

It’s time to change your motor oil today

There’s an adage: an ounce of prevention is worth a pound of cure. And while that’s true for every system in your vehicle, it definitely applies here.

If you want a car that continues to operate well throughout its life, giving you the longest lifespan possible, it’s important to keep it working well.

You can do that easily just by pulling into our service station on a regular basis. Three or four times a year, for most.

It’s not about the money you’ll spend on new motor oil. It’s about the money you’ll save on repair bills down the road.

What Shock Absorbers Do For Your Car

August 10, 2020 by Denver Express Car Care

We’ve all seen the movies where a car goes bouncing down the road. But in reality, if you start to feel your car bounce, you know you have a problem. It could be a sign your shock absorbers are worn out.

What is a shock absorber?

A shock absorber is an integral part of a car’s suspension system. The shock absorber was designed to absorb the compression and rebound of the springs. They are created to take away the bounce and spring motion produced as your car moves.

Shock absorbers keep your tires connected to the road, so you experience a smooth ride.

As your car moves, you hit a variety of things in the road – bumps, dips, even fast-acting swerves to avoid large items. Your car’s suspension system reacts to your controls, which in turn moves energy to the tires, so they continue to connect with the road and absorb this energy. Shock absorbers dampen the movement of the springs, turning kinetic energy into thermal energy (or heat energy.) Thermal heat is dissipated into hydraulic fluid.

Shock absorbers exist within a cylinder controlled by a piston that moves as the vehicle’s suspension system operates. Small amounts of fluid are released from the piston head, which helps slow down the suspension movement, further controlling the rebound of the springs. The faster the springs move, the more resistance a shock absorber provides.

That’s what shock absorbers do when they work correctly. Over time, they start to wear down.

How do you know if your shocks are bad on your car?

Most drivers rely on their senses to tell them when something is wrong with their cars. Paying attention can mean the difference between a minor repair and a major overhaul. When you hear, smell, or feel something that seems not quite right, it’s better to bring your vehicle in to a mechanic and have them check it out right away.

All of your vehicle’s systems offer various warning signs, including faulty shock absorbers. As you’re driving, you may notice any one of these items:

The vehicle bounce

Now that you know how shock absorbers work, it’s fairly easy to understand why your car would bounce when they no longer work well. Shock absorbers work together with the springs attached to your car’s suspension system. If the shock absorbers aren’t working the way they should, it allows more action from the springs. And that is going to cause you to feel more bounce from your car. If the shock absorbers aren’t there to alleviate the resistance, the energy will move into your tires, producing an uncomfortable ride.

A metallic sound

As a suspension system wears down, it produces a telltale sound of metal to metal contact. If shocks and bushings can no longer support the strut, the result will cause a knocking sound you’ll hear either from the front or rear wheels.

Diving or squatting as you start and stop

Shock absorbers help your vehicle stabilize as you pull away from stop signs and traffic lights, and control the movement as you brake and come to a stop. If the mechanics of the shock absorber can’t handle the weight of the vehicle during this action, you’ll find the front end diving down or the rear of the vehicle squatting during this process.

Body rolls

In a similar movement to diving and squatting, a body roll takes place as you bring your vehicle through turns. As the shocks start to go bad, you’ll feel your car leaning more into every turn you make. Over time, this can present safety issues, so it’s important to take action and correct the problem as soon as possible.

How long do shock absorbers last on a car?

Just like other parts of your car, finding an answer to how long shock absorbers last depends on a variety of things.

Most manufacturers will give you a ballpark number. You may see things like “10 year guarantee. ” That is subjective at best. A delivery van that puts on hundreds of miles a week will clearly need new shock absorbers long before a car that sits in the garage most days because the owner is retired.

Mileage or time frame is a starting point, but it also depends on how you drive.

It also depends on the roads you drive on regularly. Smooth highway miles are different than rural gravel roads. Lots of stops and starts can wear down the mechanics of the shock absorber long before a car that mostly drives on the highway.

Then there are also considerations around road conditions. Driving in the heat of the summer is different than driving on roads filled with mag-chloride, ice, snow, and salt. Chemicals can always play a part in how long various components will last.

Do shock absorbers need any maintenance?

All vehicles have four shock absorbers (or a strut/shock absorber combination) at each wheel. The good news is that your shock absorbers don’t require scheduled maintenance like other parts in your vehicle. This doesn’t mean they never need replacing.

Shock absorbers do fail over time. And replacing your shock absorbers is one of the more common replacements you’ll make keeping your vehicle safe and in good working condition.

But there’s another reason many people upgrade from factory-grade shock absorbers: ride quality. People often come in and state their luxury car is suddenly driving like a truck. That’s a sign you need new shock absorbers. Your ride will be smoother. It can also make a vehicle corner and brake like when it was new.

When a shock absorber goes bad, it’s not necessary to replace them all at one time. However, it’s usually recommended to replace them in pairs – both front or both rear. This is because new shocks will absorb more of the road bumps than the old. If you were to replace only one, there would be an unevenness from side to side. This could quickly cause other problems within your vehicle.

Are you ready for a smooth ride? If you’re tired of feeling every bump in the road, it might be time for new shock absorbers.

Why a Car Diagnostic Test Can Be Important To Your Wallet

August 7, 2020 by Denver Express Car Care

Every year, you schedule cleanings with your dentist, check-ups with your general physician.

Why? To ensure you stay in good health.

During your routine visit, a doctor can assess what’s going on inside by taking a few standardized tests. They poke and prod in the right places, looking for clues that will tell them something is wrong.

Your goal is to receive an a-okay, knowing you’ll be fine in the coming months. But if they find something small – just an inkling of a potential problem – they can explore further, knowing they’ve caught it early. And catching it early can be the difference between life and death.

A car diagnostic test works in a similar manner. It warns you of potential problems somewhere within your car, problems you might not see, or even detect. But they are there, waiting. They can increase quickly, requiring expensive repairs. Or worse, strand you at the least inconvenient time.

What is a car diagnostic test?

One of the greatest advancements in the auto industry was the addition of technology. As cars became more computerized, it allowed mechanics to connect with each system more effectively. Instead of guessing as to what causes a problem, mechanics can now pinpoint exactly where the problem lies, making it easier than ever to fix the problem and get you back on the road again in no time.

A car diagnostic test can either be performed at the dealer or at a reputable service station. Using specialized software, a trained auto mechanic can use the results from the car diagnostic test to pinpoint exactly where the problem lies. Thanks to built-it processors, microchips, and sensors, this computerized program will show where the problem lies. It makes it easier than ever to discover even the smallest problem within the major systems such as the engine, transmission, ignition cells, throttle, and more.

Does a car diagnostic test look at every part of the vehicle?

There is a misconception about just how accurate a diagnostic test can be.

When you receive the results from a blood test at your doctor’s office, it can tell the doctor something is wrong. But it’s up to the doctor to interpret the results, conduct further testing, and eventually get to the root of the problem.

Diagnostic testing works in a similar manner.

Through testing, problems can be revealed with a car’s engine, transmission, exhaust system, brakes, performance issues, problems with air flow, coolant, throttle issues, and more. If you have your “check engine” light come on the dashboard, for instance, it can be a warning of a small problem, such as a faulty gas cap, or it could mean something more serious, such as an engine misfiring.

The diagnostic test may provide certain clues that lead a mechanic to dig in a little further. But it’s up to his skill and knowledge levels to determine exactly what’s wrong with the car. The problem will only be fixed appropriately if the mechanic makes the right diagnosis. And that’s where it benefits you to choose your mechanic wisely.

Why should you schedule a car diagnostic test periodically?

If you’ve recently had your annual physical, you know the benefits of scheduling it once a year. In most cases, you’ll be in and out with no worries. You’ll receive a “clean bill of health,” and you’ll be on your way.

There’s a good feeling about that. You can put your fears aside if you’ve been feeling a little under the weather. You can talk with your doctor about any challenges you might have been facing throughout the year. And leave with more confidence, getting back to life.

Before car diagnostic tests, a car’s health was often left to chance. You drove the car hard until a problem presented itself. And by the time you noticed the problem, it usually turned into a major repair. It may have even left you stranded by the side of the road. That puts you at risk. It also signaled there must be a better way.

The diagnostic test helps keep you on the road trouble-free. It helps you feel more confident no matter if you’re driving on dark roads late at night, or traveling cross-country on the family road trip.

In addition to diagnosing potential problems within the systems of your car, it can also check the computer system for manufacturers’ notifications and other detailed messages about your car. It can reveal the history, and signal information about when is the best time to replace or repair.

Should I bring in my car for a diagnostic test today?

Creating a snapshot of your car’s health sounds beneficial, doesn’t it? Maybe you’re wondering when you should schedule a diagnostic test for your vehicle. You don’t have to wait for a light to pop up on your dashboard to signal it’s time for a test. This is where it pays to pay attention to how your vehicle sounds and feels.

If you notice an unusual sound, bring it in. If it just doesn’t drive the way it used to, a diagnostic test may reveal the reason.

Of course, it’s also good to schedule a “check up” at least once per year.

Are you heading out of town on the epic family road trip? A diagnostic test can help you do so with peace of mind.

Or maybe you choose to have a diagnostic test performed right before we head into the winter months. It’s a great way to ensure your vehicle is performing at peak performance, before the temperatures fall below freezing.

An annual test will help reveal small problems that aren’t yet triggered by a light on your dashboard.

It can also be a useful tool if you’re in the market for a good used car. Before you sign on the dotted line and commit your hard-earned cash, schedule a diagnostic test and it will ensure you’ve found a great car, and not a lemon-in-waiting.

Is it time to schedule your car diagnostic test?

Keeping your vehicle in good working condition takes more than new tires and an occasional oil change. To stay on top of potential problems, a diagnostic test can alert you to trouble long before it appears, giving you trouble on your daily drive. Give us a call or stop by today, and we’ll let you know exactly how well your vehicle is performing.

3 Easy Ways To Increase The Lifespan Of Your Brakes

August 3, 2020 by Denver Express Car Care

Wouldn’t it be great if you could magically wish all of your maintenance items away? Then your windows would be washed, your lawn would always be neatly trimmed, and your car would run in tip-top shape, no matter what the weather conditions throw at you.

Unfortunately, that’s not the case. Instead, you have to take on each chore yourself, monitoring the status and making choices about when to repair and when to replace.

One of the most vital systems in your car is your braking system. Imagine coming home from a weekend of skiing and not having your brakes in place. The idea is terrifying at best.

While every vehicle is different, statistics show that most will need brake replacement somewhere between 20,000 and 70,000 miles.

That’s a huge variance. And there’s a reason for that. A lot of it depends on your vehicle, and the quality of products used to build the car. But even more of it comes down to driving and care.

Are there ways to increase the lifespan of your brakes? You bet. Read on.

How brakes work

In order to increase the lifespan of your brakes, it’s important to understand how your brakes work.

A car in motion uses a lot of kinetic energy. To bring a vehicle to a stop, the brakes have to remove that kinetic energy, sometimes abruptly. Brakes do that by using friction to move kinetic energy into heat.

By pressing down on the brake pedal, hydraulic fluid is pushed through the master cylinder, which ultimately applies pressure to brakes located at all four wheels. Hydraulics is what multiplies the force behind pushing down on the brake pedal.

Each wheel contains either disc brakes or drum brakes. Disc brakes have a brake disc, a brake caliper, and a brake pad. Hydraulic fluid causes the brake caliper to press the brake pad against the brake disc. This action causes friction, which sends the heat into the brake pad. A stopping car can generate as much as 950 degrees of heat, so these pads must work, and continue to work well.

Drum brakes are similar, but contain a brake drum and a brake shoe instead. The brake drum controls wheel movement. As the brake pedal is depressed, the brake shoe pushes against the brake drum, creating friction and stopping the wheel.

What causes wear on the braking system? Time and use. The more your brakes are put into action, the more wear will be given to each part in the system. But don’t think leaving your car set will be any different. Even a car that sets will eventually have parts that crack or break. It’s important to keep your vehicle properly maintained, no matter how you use it.

How can you increase the lifespan of your brakes?

If you live in an area where there’s a lot of stop-and-go traffic (hello, Denver), then you’ll be using your brakes a lot more than someone who lives in a more rural area. This impacts how fast the brake pads and rotors wear.

Normal braking will ensure you get the longest life possible from your braking system. However, there are several habits that drivers are prone to that will actually wear your brakes out faster. Reduce or eliminate these few things, and your brake life will be extended.

Speeding

Let’s start with a big one. It’s easy to feel rushed as you move throughout your busy days. When you leave even just a few minutes late for pickup or a meeting, you’re more likely to push the pedal down a little more to try and make up the time.

Pushing the speed limit causes two reactions. First, you’re more likely to ride closely to the car in front of you. This means you’re more likely to slam on the brakes when they slow down and come to a stop. You’ll use a lot more of your brake pad as you ride the brakes to control the movement of your vehicle.

Second, higher speeds mean more wear and tear. It takes more action to slow down your car, the faster you travel.

Stick with the speed limits, and drive according to road conditions. You’ll save on wear and tear, and decrease your risk of accidents.

One foot, less brake erosion

Have you ever driven behind a vehicle where the brake lights are always illuminated? They are a two footed driver. That means they use their right foot on the accelerator and left foot on the brake pedal. Instead of taking the foot completely off the brake pedal, they leave it there, resting, waiting to strike into action. The problem is they are also wearing out the braking system way before its time.

Driving with both feet doesn’t make you a safer driver. It won’t improve your response time. Instead, it causes more problems with vehicle maintenance, wearing down the brake pads and warping the rotors.

Keep your left foot on the floor, your right foot ready to spring to action, and a watchful eye on the road. That’s still the best way to drive.

Lighten your load

Depending on the vehicle you drive, you might be shuttling around several thousand pounds. If you load up the trunk with stuff, you may be adding to your load. While you might need lots of stuff when you head out on the open road for a family vacation, leave the stuff at home when you’re just moving around town. The heavier a vehicle, the harder it has to work to stop. And that means more pressure on your braking system.

This isn’t just about what you put in the trunk either. Do you have aftermarket products lining your vehicle inside and out? A ski rack on top? A bike rack on back? Remember, the heavier your vehicle, the more pressure it puts on your brakes. And the more it takes away from your wallet.

When was the last time you had your brakes inspected?

Your brakes won’t always alert you to problems in a convenient way. Being stranded by the side of the road is never fun. It can be dangerous too.

Instead, isn’t it time for your annual inspection, to ensure everything about your vehicle is running smoothly? Not only will simple tests assure you’re driving a safe car, but it can also increase the lifespan of every major system, including your brakes.

Call today for your appointment. And drive away with peace of mind.

TSB, not USB

August 3, 2020 by Denver Express Car Care

You probably know that USB is a computer term (it stands for Universal Serial Bus). But do you know what a TSB is? If you don’t, you should, because it could be important for your vehicle.

A TSB is a Technical Service Bulletin. When a new vehicle is introduced and starts being driven by thousands of real-world users, weaknesses in the parts or the design begin to be revealed. So automakers send out TSBs, so that service technicians will be aware and know to look for those problems. A TSB can be issued for things such as a loud noise when the vehicle turns or a minivan power door that won’t close properly.

A TSB is not the same as a recall. If a vehicle has a defect that could result in people being hurt or illegal emissions, that vehicle is recalled. The manufacturer must pay for a safety defect to be fixed, usually at a dealership.

When a Technical Service Bulletin is issued, it’s an acknowledgement that the vehicle manufacturer has noticed a pattern of something not working the way it should. They also suggest the proper repair to address these known issues. The cost for a TSB is usually only covered by the manufacturer if the vehicle is still under warranty.

If your vehicle is no longer covered by a warranty, but a TSB has been issued on a certain problem, any service facility can perform the service. Ask your service adviser about TSBs that may have been issued for your vehicle. Those TSBs can be helpful for the technician to diagnose any problem you are experiencing. The TSB will also guide the technician on the best repair procedure to get your vehicle working the way it should. We’re committed to maintaining your vehicle’s performance, safety, and fuel economy.

Low Engine Oil – What It Does To Your Car

July 28, 2020 by Denver Express Car Care

What is the most important fluid to keep your car running smoothly? Gas? Oil? Something else?

Your car stays operational by ensuring all pieces are properly maintained, it’s hard to imagine how long your vehicle would run if you stopped putting motor oil into it.

Regular maintenance includes a trip to the service station every few months or few thousand miles, depending on your vehicle and driving patterns. Without replacing the motor oil, the lifeline to your car will be severed. Eventually, many problems will start showing up, such as reduced fuel economy, serious engine damage, leading to complete engine destruction.

What is engine oil?

Engine oil – motor oil – is a thick fluid that provides lubrication for your vehicle’s engine.

All motor oil is not created equal. If you head into an auto parts store, you’ll see a variety of makes and options sitting on the shelf. That’s because all motors were not created equal. If you purchased a high performance vehicle, that’s different than the family sedan. A car purchased ten years ago will also have different requirements than one you drove off the lot earlier this year.

Engine oil is sold by type and weight. That’s to keep your car running smoothly in all driving conditions. Newer cars use oil for better gas economy and oil consumption. It’s not only something drivers demand, but it’s also federal regulation. If you compare today’s engine oil to oil from twenty or thirty years ago, you’ll find it thinner. That’s for flow through. It keeps your engine running well no matter what you dish out as you drive.

There are two different categories of motor oil: mineral oil and synthetic oil. Mineral oil is petroleum based, similar to how gasoline is produced from crude oil. Synthetic oil is developed in a lab, designed for specific requirements. While mineral oil is often less expensive, it also won’t last as long once in the engine. Because mineral oil is also derived from a finite resource, there is also a question about carbon footprint.

Engine oil is designed to be a specific weight. You’ll see it rated like 0W20 or 5W30. It’s important to stick with manufacturers’ guidelines, as your vehicle was designed with a specific weight in mind. Going with another weight could reduce your fuel economy, or even impact your engine to the point of seizing your engine.

Why is engine oil important?

Engine oil is important for a variety of reasons.

Lubrication – the most important reason is for lubrication. The right engine oil keeps all of the moving parts protected, preventing them from rubbing against one another, causing wear. Metal on metal is never good. Not only would it wear individual parts out, but it can also wreck your engine. Preventing friction from having these parts wear on each other should always be your biggest consideration.

Cooling – every time you turn your engine on, it creates heat. If that heat builds, it can cause damage to the inner workings of your car. While most of the cooling is handled by the coolant system ( your radiator), motor oil provides supplemental cooling for parts of the engine where coolant can’t reach.

Cleaner – engine oil also acts as a cleaner to keep the engine clean. Over time, debris can accumulate in the engine compartment and start eroding various parts. Motor oil cleans those damaging deposits.

Why you should change your engine oil on a regular basis

When you take your vehicle in for a motor oil change, they’ll remind you to do so on a regular basis, either based on mileage or time. While service stations will do so based on simple guidelines, check with your manufacturer to determine the right course of action for your vehicle. With higher quality oils, it often means you can drive longer between oil changes. Newer weighted oil can often last up to 10,000 miles or more in between changes.

However, this isn’t an area you should skimp on. If you aren’t sure, sticking with the 3 months/3,000 miles rule is your best course of action. You can also speak with one of our mechanics and set up a time period that works well for your style of driving.

How do I know if I have low engine oil?

There are several issues that can cause low engine oil.

A faulty sensor

If the warning light turns on in your vehcile, signaling you have low engine oil, your first course of action can be to check your oil levels if you think it might be amiss. A simple oil check may be an indicator it’s a faulty sensor, not a problem with your engine oil. However, if your engine oil sensor is illuminated on your dashboard, it’s a good idea to let one of our mechanics take a look as soon as possible.

Improper engine oil

All motor oils are not created equal. That’s why it’s a good idea to go to a reputable shop where you know you’re vehicle will receive a high grade engine oil. Your car was created with specific grade levels in mind. If it doesn’t receive the proper grade, with time, it will break down faster, reduce lubrication within your engine compartment, and impact both the parts and performance of your vehicle.

Bad oil filter

The oil filter works to remove dust and metal from the oil. Without a good oil filter in place, particles can flow back into the engine. If the oil filter is bad, it can inhibit the oil from flowing freely, potentially setting off a warning signal on your dashboard as well.

Oil pump malfunction

The oil pump is designed to generate pressure and ensure the oil moves freely throughout the system. If the oil pump malfunctions either because of age or wear and tear, it bubbles into the oil, which in turn reduces the pressure within the system.

Oil leaks

Pay attention to the ground underneath your car. As you pull out of the parking space, do you notice wet marks underneath? Any leaks should be checked out by one of our mechanics immediately to further prevent damage to your vehicle.

The best way to prevent low engine oil in your vehicle is to perform maintenance and schedule regularl oil changes on a timely basis. Ignoring any of the warning signs can shorten the lifespan of your vehicle, make it less reliable, and cause you more money in the long run.

Does Your Car Have a Cooling System Leak?

July 23, 2020 by Denver Express Car Care

Imagine trying to survive outside all day in 100 degree heat without a bottle of water. It wouldn’t take you very long to start fading.

You need water to function, to survive.

Your car works in much the same manner.

Without the proper fluids, your car would quickly grind to a halt. It would perform only as good as it could, trying to pull what it needs from the various resources. Until nothing was left. The only choice it has is to quit functioning altogether.

Coolant is an important fluid your car needs to function year round, but especially in the summer months. Coolant is designed to prevent water in your radiator from boiling over. In the summer months, your vehicle can reach much higher temperatures, especially as you drive under the extreme heat we face here along the Rocky Mountains. Coolant also provides lubrication for all the moving parts it comes into contact with, keeping seals and gaskets supple, so they are less likely to harden and leak.

Coolant, also known as antifreeze, is one of the most important fluids to keep your car running properly. If you’ve noticed an odd, sweet smell after turning your engine off, you might have a coolant leak.

While the term antifreeze might have you thinking it’s only used in the winter months when temperatures fall below freezing, antifreeze is equally important in the summer months for your cooling system. Coolant – antifreeze – control’s the engine’s temperature so it won’t overheat.

A car’s radiator is filled with coolant, which is a mixture of 50 percent antifreeze and 50 percent water. The engine pumps coolant through the radiator, engine, and heating system to help keep your engine operating at the proper temperature, regardless of how high or low the temperatures climb.

When an engine starts running low on coolant, it causes the radiator to run too hot, which hurts both performance and fuel economy. If allowed to operate too long in this condition, your engine can overheat, which will damage your car, possibly bringing it to a halt. If it destroys your engine, it will be a complete replacement, a costly endeavor at best.

If you have a cooling system leak, it’s important to discover it as quickly as possible, and get it fixed. The cooling system has many different parts, something a good mechanic will know how to search out. A coolant leak could be something as simple as tightening a loose clamp, or as complicated as repairing or replacing a broken water pump. Bringing it in will allow a technician to diagnose the problem and fix it quickly to have you back on the road in no time.

How to tell if you have a coolant leak

In most cases, you’ll know if you have a cooling system leak in one of three ways.

If you notice a sweet aroma from outside your vehicle, or immediately after you turn your car off after you’ve driven it.

Look for puddles of liquid underneath your car. They are either lime-green, orange, pink, or blue-green in color. Different antifreeze manufacturers create different dye lots to help differentiate coolant from other fluids your vehicle uses. For example, engine oil is gold when new or a dirty brown or black as it’s used. Transmission fluid is a deep red color. This is one reason to park in the same spot regularly, and pay attention to what lies underneath when you drive away.

Your car starts overheating. You may also notice the temperature gauge moving towards the hot zone as you drive.

Reasons for a cooling system leak

Once you’re sure you have a leak in the cooling system, you can start to pinpoint where the leak originates. There are a variety of ways coolant can begin leaking, here are several of the most common.

You have a leaky radiator cap – the radiator is an extremely pressurized environment. If the radiator cap isn’t tightly sealed, it won’t keep the cooling system at the right pressure level. Over time, this seal can begin deteriorating or the spring may wear out, causing coolant to leak.

Your head gasket blows – the head gasket plays an important role in the engine’s performance. When a head gasket blows, it may take time before you notice a problem. The head gasket manages a wide range of temperatures, and runs with both high and low pressure within the engine. It sits between the engine block and the cylinder head, and is referred to as “blown” when it develops a leak. The engine will no longer keep the oil and coolant separate once this happens, and ultimately leads to engine failure. It can also allow the coolant to leak and drop to low levels, which impacts the ability to cool the engine down.

Your radiator has a hole – the radiator endures both low and high extremes as you drive throughout the year. That constant temperature change takes its toll over time. Corrosion within the radiator is one of the main reasons for problems with leaks. As it ages, it gets weaker, allowing sediment or debris inside. This can spring tiny holes that lead to leaks.

Your water pump – the water pump is one of the key parts that ensures coolant is being circulated throughout the cooling system. It’s driven by a belt and is located in the lower part of the engine, connected by a hose to the radiator. This hose can break or become separated, or suffer damage over time. If coolant isn’t moving throughout the system, your engine will eventually overheat.

How to avoid cooling system problems

One of the easiest ways to avoid coolant leaks is to follow a regular maintenance schedule. That means changing out the coolant in your radiator according to manufacturer’s guidelines.

Older coolant can become sour, become acidic, and start eating away at the internal parts. Regular maintenance detects problems with hoses and connection, and finds tiny leaks throughout the cooling system before they become bigger problems.

No matter what problem you notice, whether it’s a smell, a noise, or moisture underneath your vehicle when you drive away, the best way to fix a problem is to bring your car in quickly and stop the problem in its tracks.

Let us help keep your car in good working condition this summer. It’s the best way to help you stay on the road, and avoid an overheating engine on one of the hottest days of the summer.

Pre-Owned Vehicles – Vehicle Inspection Items Before You Buy

July 21, 2020 by Denver Express Car Care

You buy a car in one of two ways.

With a new car, you rely on the manufacturer to produce a high quality car. You also have a warranty in place to protect you for a certain amount of years or mileage, whichever comes first.

But when you buy a pre-owned vehicle, things operate a bit differently. Yes, you can buy from a certified auto dealer, and in some cases, walk away with a warranty. Yet many people opt to buy in a different way. They hit Craigslist to find the perfect car. Or notice a for sale sign in the window of a car sitting in their local neighborhood.

They call. They drive it a few miles. They hand over a check, and the transaction is complete.

That’s also where the heartache can come in.

A drive around the block, and a quick look under the hood won’t tell you what you really need to know. It won’t tell you if there is an underlying problem that will surface a short distance after you take title of the car.

The only way to do that is to schedule a pre-owned vehicle inspection with one of our mechanics. This will allow a professional to run a full diagnostic on it, note where potential problem spots are, and alert you to where repair and replacement potential is around the vehicle.

Why car buyers don’t request a full inspection

When you purchase a new vehicle from a dealer, you assume the car is in the best shape possible. And if it isn’t, you have recourse in the way of a warranty.

When you purchase a used car from an independent third party, you are relying on their honesty as to the condition of the vehicle.

It’s personal to them. They want the car gone. They may stretch the truth, mask potential problem areas, and sell you on the good features of the car, ignoring what they know to be problem areas.

As a buyer, you might not know that used car inspections are not only possible, but are also readily available to you.

Yes, a pre-owned vehicle inspection will cost you money. But won’t that be money well spent if it alerts you to a potential problem that could cost you thousands of dollars, and days – weeks – without your vehicle while it gets repaired? By getting an inspection before you by, you’ll know exactly what to expect in the months ahead, knowing right where your trouble spots are on your new-to-you vehicle.

People also assume getting a pre-owned vehicle inspection is a hassle. Will a third-party even allow you to get an inspection before you hand over the money. The better question might be: what are they trying to hide if they won’t let you get an inspection? If an individual knows their car is in great shape, they will be more than happy to allow a mechanic to give you a second opinion.

The easiest way to do that is to have a trusted mechanic ready and willing to do the inspection when you’re ready. It’s a simple request when you find the car you’re looking for. We’re more than happy to help you out – just let us know what you’re looking for, and give us a call when you find a potential vehicle to purchase. We’ll get the car in and out as quickly as possible, getting both you and the seller back on the road again in no time.

What a mechanic looks for when performing a pre-owned vehicle inspection

You can find pre-owned vehicle inspections at many different dealers and repair shops. Automotive repair shops across the country offer different levels of service.

However, it is wise to build up a rapport with a mechanic before you ask for a pre-owned vehicle inspection. To ensure that you are receiving your money’s worth, a good inspection should:

Verify that all equipment is functioning correctly on the car
Confirm the overall condition of the car, including wear on tires, brake pads, and other components of the major systems
Discover hidden problems that might impact your drive in the future, such as rust on the body, frame, or engine
Run a diagnostic test to raven any mechanical or electrical problems

If a mechanic is doing his job during a pre-owned vehicle inspection, they will find things like:

Poor maintenance – a good sign of this would be to discover low oil or other easy maintenance items that should be handled regularly
Low quality repair work – some people take their vehicles to reputable service stations that use high quality parts. Others look for DIY options, where they look for cost savings in every area. By looking at repair work and other modifications, you can tell if the previous owner cut corners by choosing the cheapest product lines on the market.
Frame damage – if there is any sign of damage to the frame of the car, it might indicate the vehicle was in an accident and wasn’t repaired correctly. That can impact all other systems on the vehicle, such as pulling to one side and causing premature wear to the tires or brakes.
Vehicle history reports – while you can pull some history reports online based on VIN numbers, trained mechanics are also good at spotting discrepancies in what owers may say and what the vehicle is telling them. They are trained to spot telltale signs of damage, especially if someone is attempting to cover it up.
Other – there are many other things that a good mechanic can pick up on based on what they see in a standard inspection. They can find hidden rust, fluid leaks, nonfunctioning accessories, overdue maintenance items, or odors or noises that might not be noticeable to you in a few minutes of test driving.

A pre-owned vehicle inspection is used-car-buying insurance

While no inspection can guarantee you won’t have trouble with your new-to-you vehicle in a short time period, it can help you avoid serious problems that are obvious to a trained eye. A good mechanic can flush out any potential problems that are sitting and waiting to happen to you. It gives you a good, reliable assessment of the overall condition of the car.

If you’re thinking of buying a pre-owned vehicle, allow us to be one of your first stops. We’ll ensure your car is running efficiently and will be a great purchase for you and your family.

Fuel Pump

July 20, 2020 by Denver Express Car Care

Help your fuel pump last longer. One pump killer is contamination in the fuel tank. Sometimes this comes from the fuel itself. Buying fuel at a reputable Denver station will help make sure you are putting clean fuel into the tank. Older vehicles tend to have more sediment in the tank from years of rust or corrosion from the tank itself. The tank may need a thorough cleaning or replacement.

Another thing you can do to help your fuel pump last longer is refill your tank when it gets down to about a quarter full. The fuel pump is submerged in the fuel which cools it and lubricates it. When the fuel in the tank runs low, the pump has to work harder to suck up the fuel from the bottom and there is not enough fuel in the tank to cool it. This can lead to premature wear.

When the day comes that your fuel pump needs to be replaced, Express Car Care of Denver will use a quality replacement pump that meets or exceeds your vehicle manufacturer’s specifications. The entire assembly should be replaced. Your Express Car Care service adviser will be sure to install a replacement pump that is compatible with your fuel type. For example, if you have a FlexFuel vehicle that can run on gasoline with up to 85% ethanol content, your fuel system components – including the fuel pump – must be able to withstand the corrosive effects of high alcohol content fuel.

We’d like to help you with all your car repair questions, give us a call or come in and see us.

Get Ready For Summer: Truck Maintenance Tips For Towing Your Gear

July 18, 2020 by Denver Express Car Care

All across America, the great road trip is on. Albeit differently than any summer before.

Because very few of us relish the thought of hopping on a plane in the coming weeks, more are pulling out their maps and planning an old-fashioned kind of vacation. Why not see what America has to offer? Pack your bags, hook your camper up to your truck, and let’s go!

Of course, pulling your campers, boats, water toys and more takes a lot of work. Is your truck up for the job? Here are a few truck maintenance tips to ensure your vehicle is up to the task.

Towing capacity

Have you decided this is your year to invest in new camping gear? Did you pick up a boat at a bargain price on Craigslist? Or maybe your dream of owning watercraft has finally come true. Surely your current truck can do the job, right?

Maybe not.

Don’t assume your truck has the proper towing capacity for the job. Check your owner’s manual instead. It will tell you how much pulling capacity you have without damaging your vehicle or impacting the ability to handle the load safely as you travel up and down hills and around tight corners. Too much weight on your tow could damage wheel bearings, brakes, transmission, axles, or even your engine.

Towing equipment

If you’re new to towing, be sure to invest in the right towing equipment for the job. In most towing situations, you’ll need four pieces of equipment:

Hitch

Hitch receiver

Drawbar

Hitch ball

If you have the right equipment, you’ll safely tow your equipment behind you wherever the road takes you. If you don’t, you could be staring at crushed campers and watercraft at the bottom of a ravine.

Every setup is created for a specific weight and size class. The mini camper you towed last summer isn’t necessarily the same as the boat you recently purchased. Check with your owner’s manual for classification, as well as read up on the new equipment you’ve purchased.

Trailer details

When you’re towing various toys for camping and having fun on the water, it’s no longer just about your truck. You have a trailer to think about too. That means in addition to caring for your truck before you head out on the road, you’ll have to have your trailer checked out too. Make sure you have:

Trailer lights – ensure the electrical wiring is properly attached to ensure taillights and brake lights are in good working condition.
Secure load – whether it’s simply pulling a mini trailer, or if you have a variety of toys spread out in the back of your truck, ensure it’s all properly covered or tied down. You don’t want to reach your final destination, only to discover you’ve lost half your load along the way.
Check your tires – while trailers and other towable equipment may not have a lot of running internal parts, you will be dependent on the wheels and tires to get you where you’re going. Sometimes you off-road it, being more vulnerable to things that can flatten or blow a tire. Are they in good shape before you leave?

Safe truck checkup

When you’re about to head out on vacation, it’s a good idea to give your truck a thorough checkup before you leave home. When you drop off your truck for an inspection, mention your vacation plans and what you’ll be towing. That will give our mechanics a better idea of what to look for, and make recommendations based on your plans.

While these aren’t the only things you should check, it’s a starting point.

Brakes – not only will you be using your brakes to stop your truck, but you’ll also be adding weight behind you in what you’re towing. Having brakes that are even slightly worn could be a hazard to your safety.

While it might be a natural tendency to ride the brakes with the added weight behind you, especially as you navigate turns and hills, this can only increase the chance of overheating them. Instead, choose to drive at a slower speed. Some trailers come with their own braking system. While this takes practice to be able to coordinate the two tougher, it can reduce the likelihood of putting too much pressure on your own braking system.

Cooling – no matter where you’re driving to this summer, chances are you’ll be using your air conditioner to help you stay cool. This intensifies the possibility of your truck breaking down. That extra load puts more stress on your vehicle, so ensure all of your cooling system parts are working well before you head out. That includes the radiator, water pump, thermostat, cooling fan, and other systems attached to your vehicle.

Suspension – check both your truck’s suspension system and whatever you’re towing as well. For driving around town, your truck may have lighter duty shocks that can present problems when you start to pull a heavy load. A heavier duty shock absorber will help keep your vehicle stable while towing. Plus it will make your ride smoother too.

Fluids – not only will you be pulling a heavier load wherever you go, but you’ll also be doing it on potentially some of the hottest days of the year. It’s time to check all of the fluid levels throughout your vehicle to ensure you’re topped up and ready to go.

Start with motor oil. This isn’t a time to skimp and look for bargains. Instead, trust brand name synthetic motor oil and transmission fluid to give your engine added protection throughout the summer and beyond. Replace oil filters to improve performance. Top up things like windshield washer fluid – those roads can become muddy and dirty from brief rainstorms and more.

It’s summer – get out there and have fun!

Before heading out on your summer adventure, spend a little time preparing your truck for the process.

It’s been a stressful year. No matter if you’re heading off the beaten path, or will be following others into some of the most well-loved monuments in this country, following a few truck maintenance tips before you head out will ensure you arrive safely, and that you don’t spend more time on the side of the road then you do having fun at your final destination.
