Simple Answers for Water Pump

August 31, 2020 by Denver Express Car Care

Question: My water pump went out and it costs much more to replace than the ones I’ve replaced in the past. My technician said it’s because of where it’s located. Why is that?

Simple Answer: Some water pumps are driven by the serpentine belt and are bolted on out in the open with the alternator, air compressor and such…other water pumps are driven by the timing belt. These water pumps take a lot of labor to access and replace. We suspect your current vehicle has a water pump that is driven by the timing belt.

Water pumps are fairly simple devices that circulate engine coolant/antifreeze around the engine and out to the radiator. Like every mechanical device, they eventually wear out. Although having a cooling system service done on schedule at Express Car Care will extend the life of your water pump and its seals and gaskets, it will eventually fail and need to be replaced.

The water pumps that are driven by the timing belt (the belt that controls when your engine intake and exhaust valves open) are attached directly to the engine block. The timing belt system has a protective cover. The serpentine belt and all the accessories are located over the timing belt cover. So getting to the water pump requires removing a lot of parts which then need to be replaced.

When the water pump must be replaced, we at Express Car Care, think it is a good idea to go ahead and also replace the timing belt, timing belt tensioner and idler pulleys. First, because the timing belt may have been contaminated by leaking coolant; second, there is a schedule for replacing your timing belt and you might as well make the modest additional cost while everything is taken apart so you can avoid the same labor cost down the road.

By the way, the reverse is true as well: When you are replacing your timing belt on schedule, go ahead and replace the water pump at the same time. It would be a shame to spend the money on one of these replacements only to have to do it all again in a few months because the other part then needs to be replaced. Do them at the same time and start the clock over for both.

Your Car’s Heating and Cooling System Does More Than Keeping You Comfortable

August 29, 2020 by Denver Express Car Care

When most people think about temperature control inside their vehicle, they usually consider them to be two separate systems. Heating is used in the winter, cooling is used in the summer, with the most important part of the process being comfort.

Imagine arriving at your destination if you’ve driven across town in one-hundred degree heat and no air conditioning. It would be a miserable experience. Equally so as the temperatures creep towards zero, without a heater warming the interior cabin.

What makes both possible is the ventilation system that connects all the parts together. Yes, you need a heater and an air conditioner. But without the ventilation system providing a way for cooled or warmed air to move, you would be left to control temperatures by raising and lowering your windows.

So, how does your car’s heating and cooling system work?

Let’s talk about how your heater and air conditioner are related.

How a car’s heater and air conditioning works

Your car’s heater is a smaller version of the cooling system. Coolant circulates through a small radiator, often called a heater core. A fan is used at the front of the heater core to blow the cold air from outside over the fins. As this air moves through the heater core, it heats and becomes the warm air that is pumped inside the cabin through the heater vents.

The cooling system consists of a compressor, condenser, and evaporator. Refrigerant is compressed in the compressor, which turns into a hot gas. It moves to the condenser where it is cooled to a liquid state. It continues to move through the system, returning to a low-pressure gas as it rapidly cools in the evaporator. A fan blows over the evaporator during this process, cooling the air that blows through the vents inside the cabin of your vehicle.

Sounds easy enough, right? It’s easy to see how they are both connected. But they intertwine even more.

As the engine runs and causes friction and combustion, heat builds. Most of this is expelled through the exhaust system, but the remaining heat must be handled in some way. Coolant and water mix within the engine block and radiator to release the heat into the atmosphere. On cold days, that heat travels inside your cabin for warmth. But on warm days, your engine could overheat if something disrupts this process. That means your heating system is responsible for keeping your engine functioning properly all year long.

Likewise, on cold winter mornings you might wake to a layer of frost spread across your windshield. It’s not just your car’s heating system that warms it up, it’s the cooling system too. Multiple components all work together to pull humidity out of the air, helping to defrost your windows so you can see to drive. If you notice defogging issues, it may be time to recharge your air conditioning system, or check for leaks or damage.

What are the common problems with a vehicle’s heating and cooling system?

Have you ever heard of a vehicle needing to recharge the air conditioning system? That means ensuring the refrigerant is at proper levels to do its job well.

From time to time, refrigerants can wear down or leak. If this is the case, the equipment should be repaired before refilling to ensure maximum efficiency. It can be difficult to tell as some leaks are tiny at best. But you can watch for puddles forming that are either green or orange. Healthy coolant will be green (ethylene glycol) or orange (Dexcool). If it puddles as more of a rusty color, that means the rust inhibitor in the coolant is no longer doing its job, so rust and scale are building up. Changing it out will breathe new life back into your heating and cooling system.

Topping off the coolant may seem like a quick and easy thing to do. You can buy coolant at your local auto parts store. But the bigger question is: why was it leaking in the first place? The way the system is built, it should never leak coolant. That means somewhere there is a compromise to the system. It could be a cracked hose. It might be a radiator cap gone bad. It could be a damaged water pipe. But if you don’t get to the root of the problem and fix it, you’ll continue to have trouble even after filling up the coolant.

Depending on how old your vehicle is could be a problem too. The EPA phased out the use of R-12 coolant in all refrigeration systems, replacing it with R-134. R-12 has been determined to cause ozone depletion, impacting the ozone layer. So it’s been phased out over time with one safer for the environment. If you still drive a vehicle that uses R-12, you may need to retrofit the system to handle the newer R-134 coolant. Seales, hoses, even the compressor might need to be swapped for a newer model.

Corrosion will also cause the core to leak. Over time, it may leak steam into the interior cabin and fog up your windows. You may also detect a leak by a sweet smell coming through your vents when the system is in operation.

Prevention methods

In most cases, your car’s heating and cooling system won’t create a lot of problems. If you pay attention to your car, running standard performance checks every time you drive, you’ll notice a problem long before it grows into something bigger. If you notice a problem with heating or cooling, hear a strange noise, or smell something unusual, don’t ignore it. Once may be a fluke, but if it happens multiple times, bring your car in for an inspection.

With winter coming, it’s especially important to ensure your heating system is working at its best. Have you noticed problems with your air conditioning this summer? Is your car not as cold as it once was? Schedule a maintenance visit today to ensure your heating and cooling system are fully operational.

It will ensure you have a stress-free driving experience every time you head out the door.

Is Your Car Experiencing One Of These Common Suspension Problems?

August 26, 2020 by Denver Express Car Care

From the moment you drive a brand new car off the lot, it’s placed in stressful situations every day.

That curb you nudged going around a corner? That may have damaged your tire.

That pothole you hit this morning on the way to the store? That may have compromised your suspension system.

Your car was perfectly designed, put together with care. But the world around you is anything but a perfect place. You can dodge a car that turns into your lane, jump when a rock hits your windshield and causes a crack, flinch when damage in the road jars your car, and all that is getting out of your neighborhood.

Imagine what happens to your car over the course of a year!

What does the suspension system do?

Before we get into all of the things that cause common suspension problems, let’s first take a look at what it does for your vehicle.

Imagine heading out on the open road, and pushing the pedal to the floor to reach 60, 70 miles per hour and more. What gives you control is your suspension system. What makes it a comfortable ride at every speed is your suspension system. Without it, you’d quickly spin out of control.

The primary function of the suspension system is control. It maximizes the connection between the tires and the road. It provides steering stability. It creates even weight distribution between all four wheels. It ensures comfort by absorbing every bump in the road. It limits the stress placed on other parts of the car, ensuring your vehicle sustains a long lifespan.

The suspension system consists of:

Tires
Air pressure in the tires
Shocks
Struts
Springs
Arms
Bars
Linkages
Bushings
Joints

All suspension parts are located somewhere between the frame of the vehicle and the road. It is designed as a protection system, creating a buffer between your car, the road, and you safely inside.

How do you know if your car has suspension problems?

Even though you can select a car from many different manufacturers, in many different sizes and shapes, they are all built with the same structure and way that they operate. Yes, you have the choice of purchasing many different types and styles of tires, for example, but they are all designed to provide the same basic function.

That makes it easy to recognize when things aren’t working right, no matter what vehicle you drive. There are common suspension problems that materialize when a part weakens or no longer works.

Pulling to one side

At the top of the list, one of the most common signs of a suspension problem is when the car pulls to the left or right while you drive. It’s also a difficult problem to diagnose without the help of a trained mechanic. That’s because it can be a whole host of different issues. It could be an alignment issue. Uneven tire wear. Or a problem with the steering wheel. It can be a problem with the tire rack. Or possibly a sticking problem with a brake caliper.

Every pothole you hit, every bump in the road can jar something loose. If your alignment is out of whack, there’s a reason for it. Some part has either come loose, or is broken altogether. And the only way to get your car back in good working condition is to get to the root of the problem.

A bumpy ride

What happened to your nice, smooth ride? Suddenly, your car feels like an old beat up truck.

A rough ride is a clear indicator that your shocks and struts are worn out or in need of repair. Shock absorbers are designed to absorb every bump in the road. They have hydraulic fluid inside that helps dampen the bouncing motion as it connects with the road. If they lead, your performance suffers.

One corner sits lower than the rest

As you walk up to your car, take a quick look at how it sits. It should always be level. If it isn’t, there’s a problem. When one corner sits lower than the others, it’s likely a damaged spring. You may also start noticing a clunking noise as you hit a bump or turn a corner. That’s because the spring can no longer support the weight of the vehicle.

The shock and the spring are interconnected. If the shock is blown, it overcompensates by compressing the spring, lowering that side of the vehicle. Even the slightest height variance can be a sign of a problem.

Nose dives and rolls

If your car nose dives or leans forward as you brake and come to a stop …

If your vehicle rolls or leans side to side as you turn into corners …

If your vehicle squats or leans back as you accelerate from a stop …

You have a suspension problem.

Difficult steering

Have you ever had a hard time steering your car? Normally, it moves easily, one hand can take control. Then it grows in difficulty, it might even feel like it slips as you turn. This can be caused by a number of problems, including low power steering fluid, a faulty steering pump, a leaking power steering rack, or worn out arm bushings.

The best way to find the root of the problem is to schedule a maintenance visit with one of our mechanics.

Can you fix suspension on a car?

If you notice any of the common suspension problems listed above, to remain safe, don’t drive your vehicle any more than you have to. Bring your car in quickly to avoid further damage.

The biggest reason is one part can impact others. And what may have been a few hundred dollar repair can escalate into the thousands. It can also escalate from a minor repair into an emergency situation.

Imagine a problem with low tire pressure suddenly moving to critical level with a tire blowout.

That’s just one example of things that can go wrong.

If you suspect you have a suspension problem, don’t delay. Have one of our trained mechanics take a look and diagnose the problem today.

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.

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.

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.

Is Your Transmission Failing?

July 14, 2020 by Denver Express Car Care

If you’ve ever driven a vehicle with a manual transmission, you became more aware of how much it shifts as you drive around. You shift into reverse to move out of garages and parking spaces. You move from first to second, to third and fourth gears as you speed up and slow down from stop signs and traffic lights.

When you move to an automatic transmission, it works in much the same way. The difference being that the internal workings of the car do the job for you. No pushing in the clutch and moving the gears into position.

The transmission system transfers power from the car engine to the wheels. It’s what gives your vehicle mobility. It’s what allows your car to move backward and forward.

As you can imagine, a lot of stress is put onto each of the components within the transmission system over the years. That’s why transmission failure is common; it’s not a matter of if, but when. The transmission will require repair work the older it gets.

The good news is there are warning signs.

If you pay attention to the signals, you can catch problems early. That can save you from being stranded, and prevent expensive repairs in the long run.

How do you know if your transmission is failing?

Dashboard light

Your vehicle was designed to warn you well in advance of serious threats to your car’s systems. Pay attention to lights on your dashboard. A lit up check engine light can mean a variety of things. It can be a simple repair, or a sign of a bigger problem. Don’t ignore it. Instead, schedule an appointment with one of our technicians as soon as possible so we can diagnose the problem and get you back on the road without issue.

Struggles to switch gears

Sometimes, with an automatic transmission, you start to hear it struggle to find the right gear. If you have a manual transmission, shifting becomes more difficult, often feeling like you have to add force to move it between the various gears. This could be a signal your transmission fluid is low, or the mechanic you trusted your car with put in the wrong kind of fluid.

Slipping gears

Another thing you might notice is that your vehicle’s transmission tends to impulsively slip in and out of place. This can be highly dangerous if you’re on a busy road and your gears slip. Imagine flying down the highway from a day up skiing, and your gears slip to neutral. If you feel this at any point, bring it in to have it evaluated as soon as possible.

Grinding

This is more common in an automatic transmission, where a grinding or shaking occurs as you move between gears. This is one of the clearest indicators that your transmission is failing.

Dragging clutch

With a manual car, if the clutch fails to disengage the clutch disk from the flywheel as you press down on the clutch pedal, it’s a sign your transmission is having problems.

Leaking fluid

Always be conscious as you approach your car for visible signs of a problem. Transmission fluid is dyed red in color to help distinguish it from other fluids. It also has a sweet smell.

Burning smell

While your engine is running, if you ever smell a burning smell, it’s time to bring it in to be serviced immediately. It’s often an indicator that your transmission is overheating, which could be from something as simple as low transmission fluid. The faster you repair it, the less risk you have of causing further damage to the system.

Unresponsive

In some cases, your car will refuse to respond to any attempt to change gears. If you can’t move from park to drive, it’s a problem with your transmission. Your only course of action may be to have it towed in for service.

How to properly maintain a transmission

Now that you’ve determined you may be experiencing problems with your transmission, how do you maintain it? How do you ensure you won’t run into trouble at the most inconvenient time?

First of all, remember regular maintenance is the key to your vehicle’s success. You should also pay attention to your car, and be alerted to any changes that may present a problem.

Check the level of your transmission fluid regularly, depending on your make and model. Some vehicles have a dipstick similar to your motor oil for easy access. Still others are closed systems, and require knowledge and a few tools, or bring it in and one of our mechanics can check the levels for you.

You should also schedule an automatic transmission fluid service change every 30,000 to 60,000 miles, depending on your vehicle’s requirements. The old transmission fluid will be flushed from the system, the fluid pan removed and cleaned, and a new filter will be installed to the correct amount.

Be aware of the way you drive. Slow down. You should never make quick switches from drive to reverse, or reverse to drive, especially if the car is still moving. In most cases, this will stall the engine, and possibly do a lot of damage to your transmission.

Be conscious of how you drive. Smooth acceleration helps to allow gears to change at the correct times, and provide you with the most fuel efficient behavior.

Take care of your transmission

You may have heard the horror stories of drivers facing expensive repair bills installing a new transmission. And we’re not going to lie, a replacement can be one of the most expensive auto repair bills you’ll ever receive.

Instead of waiting for that repair bill to come, commit to regular maintenance instead. By watching your vehicle and getting to know how it acts, you’re more likely to recognize when something goes amiss. That means you can drive it into our service station long before you have a seized transmission.

We’re here to help you keep your car running, no matter how old it is or how many miles you’ve put on. Let us give you a quote today.

Why It May Be Time For Wheel Alignment

July 11, 2020 by Denver Express Car Care

When you drive your car off the showroom floor, everything about it is in perfect condition.

From the moment it hits the open road, your car is at risk. Slam on the brake pedal and it impacts your braking system. Hit a pothole, and it can knock your wheels out of alignment.

The trouble is, most of the damage done to your car isn’t something that impacts it right away. Instead, it accumulates over time.

That pothole in the middle of the lane you always drive in to work? Yep, every time you hit it, it continues to impact your car. Bolts can loosen. Joints can come apart. And wheel alignment? Yep, that happens gradually too. Every bump you hit, every pothole you hit a little too hard, every curb you scrape and bump, it all adds up over time.

Why is wheel alignment important to my vehicle?

Wheel alignment is important for one very obvious reason: driveability. If you want a smooth ride as you drive to work, drop the kids off at school, or take your family out on the open road, a periodic wheel alignment is mandatory to keep your car working properly. Of course, there are other reasons too.

If your wheels aren’t connecting with the road properly, it also means your tires are being impacted every mile you travel. If a wheel is bent, it pulls the tires away from the road in certain spots. That means uneven wear. It also means the lifespan of your tires will be shortened.

When your wheels are in proper alignment, the entire suspension system is working together, keeping you pointed in the right direction. Without movement, you move in a straight line. But when wheels are out of alignment, that balance can shift and turn. Have you ever felt a pull to the right or left when you’re moving down an open stretch of highway? That’s a problem with your wheel alignment. It can cause other systems more wear as you overcompensate for the problem.

All of these extra problems can cause one more failure – gas mileage. It takes more energy to overcompensate for problems throughout your vehicle. If you start to see a slip in mileage each time you fill up your tank, it might be a wheel alignment issue.

How will I know if I have a wheel alignment problem?

Wheel alignment isn’t something you’ll find a dashboard warning light for. Instead, you’ll only discover you have a problem in one of two ways.

1. Regular checkups. If you let one of our mechanics check out your car periodically, we can find and correct issues before they become bigger problems.

2. Watch your tires. The easiest way to tell if you have a wheel alignment problem is to watch your tires for uneven wear. The tires should wear evenly across the tread. If you notice excessive wear on the inside of the rear tires, for example, it’s an indicator you may need an alignment. It also could be a sign of too much weight in the trunk.

How will my driving be impacted if the alignment is off?

Watching for uneven wear on your tires isn’t the only sign of an alignment problem. There are other noticeable signs you can watch for as you drive.

When your vehicle pulls to the right or left as you drive. You’ll tighten your grip on the wheel as you feel your car slowly moving one way or the other.
A steering wheel that looks crooked instead of straight. As you drive, your steering wheel should return to its original position. If you have to turn it slightly to keep it in the lane, it may be a sign.
Your tires may squeal and make noises. That high pitch squeal is because the wheels aren’t connecting the way they should.

Now what?

What it takes to calibrate a vehicle’s wheel alignment

You can’t look at your wheels and know you have a problem. It requires precision to ensure your wheels are calibrated perfectly, giving you the smoothest ride possible.

When you bring your vehicle in, alignment is performed using advanced computerized alignment equipment. Weights can be mere fractions, bringing all four wheels into alignment.

Our technology:

Measures all four tires and sets the alignment according to manufacturer’s guidelines. The more accurate this process is, the smoother your ride. It’ll also improve your gas mileage.
Provides an accurate reading. You can’t eyeball this, which is how it was performed years ago. Today’s technology is better than ever, meaning we can get accurate readings to ensure you’re driving out of our garage with the best alignment possible for your vehicle.
Understands the guidelines for your vehicle. A Prius will have different requirements than a large SUV.

How long does it take for a wheel alignment?

Like every service we perform, it depends.

If everything goes smoothly, you can be back out on the road shortly. But as we dive in and discover problems, it may lead to other issues.

Each wheel may have up to three alignment angles that need adjusting. They’re called caster, camber, and toe. Three alignment angles – four wheels – that means up to 12 adjustments needed for servicing. You can’t drive in, plug it in, and go. It may take a little time.

Because you have four wheels, all four must be adjusted at the same time. Performing one wouldn’t give you the right calibration to ensure your entire vehicle is driving the way it should. Instead, it’s essential to adjust the front wheels to be at a proper angle to ensure the back wheels operate correctly too.

An alignment check inspects both the steering and suspension systems. It will ensure your tires are pressurized correctly, and are still in good operating condition. It will adjust camber, caster, and toe angles, as needed. That may mean new parts and labor charges, depending on the issue. And finally, a road test. We want to drive it, to ensure it feels good when connecting with the road.

Sometimes your warranty requires occasional wheel alignments to ensure it’s in proper working condition. Check with your manufacturer, to ensure you stay within compliance.

Car Maintenance Items Before Your Road Trip

July 7, 2020 by Denver Express Car Care

What will the summer of 2020 be remembered for? Recovering from a pandemic will be high on the list. Roadtripping is also going to be one of the most popular activities for families.

Forty-six million Americans say they will jump in the car and visit someplace on their bucket lists during the summer. If the coronavirus has canceled your big traveling plans, and you’re looking to stay a little closer to home, roadtripping just makes sense.

Right now, a lot of us are looking for a little escape. After being locked up at home with no place to go, even if you love your home, it’s looking a little closed-in right about now. The open road, the wide open skies, and new-to-you territory sound good right now.

But in order to make it there safely, it’s important to ensure what you’re driving gets you there without trouble.

Has your car been sitting in the garage, with only trips to the grocery store keeping it running?

Has your pickup been parked, with no place to go?

Are you sure they’ll get you where you’re going, especially if you’ll be driving into the middle of nowhere, without a service station in sight?

Car trouble is bad anytime it happens. But when your car doesn’t start in the office parking lot, it’s a minor inconvenience. If your car dies on the open road, it can be downright dangerous.

Before you leave home, there are a few simple steps you can take to ensure your car is the last thing you’ll have to think about as you’re having fun with the family.

How do I know if my car will make a long trip?

If you have a brand new car, you might not think twice before hitting the open road. But what if your car is three years old? Or five?

In most cases, if your car has been operating well, you’ve provided it with routine maintenance, you attend to issues as they occur, and it runs well for you as you carry out your daily tasks, it should run for you on a road trip as well. If it hasn’t given you trouble as you drive around your neighborhood, there’s no reason to think it will act up on your trip.

Being aware is the most important part of car maintenance. Watch for anything new that arises with your vehicle.

Are there any fluid leaks?
Do you hear any new noises?
Does a light shine on your dashboard readings?
Does your car act similarly to how it always has?

If you haven’t noticed anything new, chances are it’s in good shape to make your road trip.

How do I prepare my car for a long trip?

Are you wondering if your car is in good enough shape to go on a road trip? Whether your trip is a few hundred miles, or you’ll be adding several thousand as you venture far from home, being stuck without a car isn’t a part of your plans.

Even if you take care of your vehicle regularly, if you haven’t had it checked in a few months, doing so right before your trip can give you added peace of mind. Scheduling a car maintenance appointment will allow one of our mechanics to check the important things, ensure everything is in good working condition, and enable you to head out without having to worry about your car.

Here’s what we’ll do.

Check fluids

Fluids are the lifeblood of any vehicle. It’s not just an occasional oil change that keeps your car running well. But regular oil changes are an integral part of keeping your car moving. Oil changes are usually done based on mileage. Will you hit that point during your trip? Then it’s a good idea to have your car serviced before you leave, to ensure it operates well throughout your trip.

Oil keeps many components operating well, such as the pistons, crankshaft, and camshaft. Mechanics will tell you to change your oil somewhere around every 5,000 miles. Manufacturers may go as high as 10,000 miles, depending on your make and model. Check with your owner’s manual, and talk with one of our mechanics to get on a schedule that works best for your needs.

Other fluids you should check include:

Radiator fluid – this is also known as coolant or antifreeze. This helps pull heat from the engine and dissipate it through the radiator. A mechanic can ensure a proper amount of fluid is in the system, and flushing it every 40,000 to 50,000 miles will keep it working its best.

Brake fluid – brake fluid keeps the brake lines working well. When you push on the brake pedal, brake fluid flows through the brake lines, enabling the brake pads to clamp on the rotors, and slow and stop your car. Flushing the system every 25,000 miles or so will ensure your brakes work as designed.

Power steering fluid – this fluid ensures your steering is responsive to your movements at any speed. If you notice a change in the way your car steers, and it takes more movement to go the direction you choose, it’s time to change out the power steering fluid. Many manufacturers recommend every 50,000 miles or so regardless.

Windshield washer fluid – long trips in the summer mean plenty of bugs and dust accumulating on the exterior of your car. Topping off the windshield washer fluid will allow you to keep your windshield clean no matter how many miles you drive.

Tires

As you would expect, your tires are essential for safety. Know how many miles of wear they have, bring your car in for inspection to ensure you’ll stay safe throughout your journey. This can alert you to potential problems, such as uneven wear marks, or faulty tread.

If you don’t have a sensor to alert you with pressure problems, be sure to check tire pressure every 1,000 miles or so. Even if your tire pressure is correct, it’s a good idea to rotate your tires every 8,000 to 10,000 miles or so to help them wear better and last longer. Tires should also be replaced every 25,000 to 50,000 miles. Not sure how much tread you have left? Do the quarter test. Insert a quarter into the tread. If it doesn’t cover George Washington’s hairline, it’s time to think about replacing your tires.

What other car maintenance items do you need before a road trip?

Cars have numerous components that need to be checked and observed over the years. The better you know your car, the more you’ll be aware when it’s time for replacement.

Other components that may need servicing or replacement include:

Brake pads – they provide friction needed to slow and stop your vehicle. Depending on the brake pad, you can expect anywhere from 25,000 to 70,000 miles before replacement. Keep in mind that brake pads may not always wear evenly from side to side. Be sure to have all brakes looked at and tested before heading out on the open road.

Air filters – especially in summer, you’ll be subjected to dust, dirt, and bug entering the engine and interior, clogging the filters. This can impact your drive as well as affect engine performance. New air filters for both your engine and interior cabin every 10,000 to 15,000 miles will give you a better ride.

Bulbs – when was the last time you checked your headlights? How about your brake lights? Make sure all of your lights are working properly to help keep you safe on the open road.

Belts and hoses – over time, belts and hoses can wear down, leak and crack. That can allow fluid to leak, and increase the potential of being stranded. Just a quick check can ensure your car is in its best condition for a safe trip, no matter where the road takes you.
