Extend The Life of Your Vehicle With These Easy Maintenance Tips

April 21, 2022 by Denver Express Car Care

If you’ve shopped for a new car lately, you might have had sticker shock at how much prices have increased.

According to Kelley Blue Book, the average price for a new car has skyrocketed to just over $47,000.

Does that make you look at your current car a bit differently?

Want to extend the life of your vehicle, and ensure it stays running for a very long time? With these easy maintenance tips, your car will continue to run well for years to come.

Get started by reading your owner’s manual

Many vehicle owners can’t even remember where their owner’s manual is. But it’s one of the most important guides to have as a vehicle owner. Spend some time reviewing the recommended maintenance items. Manufacturers know their vehicles best, and will give you specific guidelines for maintenance and care. Following their “insider” tips will ensure your car stays running well for life.

We also recommend establishing a logbook for your vehicle. Keep it small, and carry it in your glove compartment. Record each of your maintenance visits, and update it with repair work. This gives you a way to see what you’ve done and what’s needed next at a glance.

Never push a cold car

When you rise in the morning, you stretch, move slowly, maybe reach for a cup of coffee. You have wake-up routines to help get you going. Your car works in a similar manner as it brings the various systems to life. Cars don’t need a lengthy warm-up process, but it is wise to let them get to operating temperature before pushing the engine to its full service.

Extend The Life of Your Vehicle With These Easy Maintenance Tips

Pay attention to your dashboard

Pilots have a checklist they run through before climbing into the cockpit for takeoff. Car owners would benefit if they had a similar process. Today’s modern vehicles come with over two dozen computer modules working to keep your car functioning, hundreds of electrical components keeping everything together, with an array of sensors keeping you safe and alerting you to potential problems.

When one of those dashboard icons illuminates, it’s important to act immediately. But the statistics show that the majority of drivers on the road today have no idea what most of those lights mean. If your “check engine” icon lights up, what will you do? People often keep driving, promising themselves they’ll “fix it” when they have time. Trouble is, these same drivers travel hundreds of miles until it escalates into a bigger problem, with a much larger repair bill. Even if money is tight, you’re much better getting these issues checked immediately to avoid even more costly repair bills in the future.

Check and replace fluids regularly

Most of us check and replace motor oil regularly. But when it comes to checking and replacing other fluids, we may not do so with such regularity. Today’s cars use a variety of fluids for lubrication, circulation, and to ensure your vehicle runs smoothly. Wear and tear can compromise these fluids, which in turn can impact the various parts and components it’s designed to service.

Basic fluids your vehicle relies on include:

Motor oil
Coolant or antifreeze
Brake fluid
Power steering fluid
Transmission fluid
Windshield washer fluid

Motor oil should be changed every 3,000 miles or so. Other fluids might last a lot longer. This is where getting to know your owner’s manual is a good idea, and can help you place inspections into your schedule.

Check your tires

Tire pressure helps regulate how well your vehicle handles. While a dashboard light may illuminate when tire pressure is low, it’s still a good idea to pay attention to pressure level. It helps your tires last longer, and impacts fuel efficiency with every tank of gas you use.

You should also inspect your tires regularly, and ensure they aren’t wearing unevenly or getting low on tire tread. Colorado weather can be harsh on tire wear, dealing with extreme cold in the winter followed by blazing heat in the summer. If your tires don’t have proper tread, your safety is more at risk.

Keep it clean

While it might seem like a simple maintenance tip, keeping your car clean is one you should fit regularly into your calendar. Colorado roads are filled with chemicals from snow removal strategies. Mag-chloride can stick to your undercarriage and wreak havoc on paint and other components. Road tar in the summer is equally as damaging, sticking to the paint and deteriorating the integrity.

Washing it regularly will help retain its value. Regular waxing will also provide added protection, reducing the chances of rust and other blemishes.

Plan out your trips

The hardest thing on your engine, the one thing that increases wear and tear is starting up your vehicle and traveling short distances. Cold starts are the hardest on your car. We’ve grown used to running short errands depending on our needs and desires. But if you can plan out your trips and bunch them together, your engine will thank you. The most power goes into a cold start. Once you have it running, keep it running for a while to ensure everything is well charged and running optimally.

When you do buy a new vehicle

There comes a point in time where we all purchase a new vehicle. In today’s world, a new car is a valuable purchase.

Extend the life of your vehicle with simple maintenance items. Start your car’s life outright by being gentle for the first 1,000 miles. This is when any impurities left in the system after production are still working their way through the system. Being gentle on your engine means they’ll flow through without incident.

Then bring your vehicle in for a 3,000 mile motor oil change, and a quick inspection to ensure everything is running with ease. Following these simple steps will ensure your car’s engine will run well for thousands of miles, and you’ll be happy with the vehicle you purchased.

Car Maintenance Tips That Will Improve Fuel Efficiency

April 18, 2022 by Denver Express Car Care

As cars first became a mainstay in our everyday lives, fuel efficiency wasn’t even on our radar. Early manufacturers paid more attention to how fast a car could go, or how comfortable it was.

Still, cars in the early twentieth century consumed fuel very well. Ford’s Model T got up to 21 miles to the gallon. That’s only 6 miles per gallon less than the average car sold today.

It wasn’t until the 1970s that fuel efficiency became more popular. The Arab oil embargo created a worldwide shortage, causing fuel prices to skyrocket, and talks resumed about improving vehicles for less reliance on oil.

What is fuel efficiency?

Fuel efficiency refers to how well your vehicle consumes fuel. It’s become a key consideration when consumers search for new vehicles, and is currently driving the electric car market.

Fuel efficiency refers to how far a car can go with the fuel it consumes. It measures in miles per gallon, and is one of the main ways manufacturers can differentiate themselves from the competition.

Fuel efficiency is relative to other cars around it. Consumers shop based on their needs. A person with a fifty-mile commute each day may have different needs than someone who works remotely. Their needs and beliefs drive what cars they purchase, ultimately driving demand.

Fuel efficiency isn’t just about how many miles per gallon. Fuel efficiency also impacts how much pollution a car releases into the environment. As we’ve become more aware of how emissions affect global warming, manufacturers have once again gone back to the drawing board, looking for ways to make cars better.

Car Maintenance Tips That Will Improve Fuel Efficiency

A more efficient car saves on how much a vehicle consumes, as well as how much it pollutes. If you want to reduce your carbon footprint, increasing fuel efficiency is a start.

But it isn’t the only way.

Car maintenance can also make a difference. If a vehicle is well cared for, it runs cleaner and pollutes less no matter how many miles per gallon it gets.

Where do you start?

Regular tune ups make a car more efficient

When you visit your doctor once a year, it’s designed to check in and ensure everything is working well. Simple blood tests can reveal areas of concern.

Tune ups are designed similarly. It’s a way to bring your vehicle in for a check up, to ensure the engine is working well and doesn’t need repair. Your car’s engine is the heart of the system, and keeps many of the other parts working well. If a problem exists within the engine compartment, it can bring down efficiencies throughout the system. The Department of Energy has stated that when a car fails an emissions test, repairing it can improve performance anywhere from 4 to 40 percent.

Balance, rotate, and inflate your tires

The tires help connect you to the road, and provide proper support as you drive along. If they aren’t doing their job effectively, you’ll see the evidence in multiple ways.

It starts with ensuring they are properly inflated. Under-inflating them will decrease the surface area that connects with the road. Too much tire pressure, and you increase the strain, increasing the chance that they might blow.

Because your tires move and change regularly, it’s a good idea to have them rotated and balanced to keep them in their best condition. Manufacturers recommend balancing and rotating every 3,000 to 6,000 miles, or whenever you notice a problem. Balance issues often result in a vibration in your steering wheel, seat, or floor. This is a good time to pull in and ensure everything is working well.

Change the motor oil

When it comes to changing your car’s oil, stick with a regular schedule. The general rule is 3 months of 3,000 miles, whichever comes first. Today’s cars are more efficient than ever, with many manufacturers increasing recommendations. Check with your owner’s manual for what’s best for your vehicle.

As motor oil ages, it gets thicker and decreases the overall efficiency inside the engine. It can cause more friction, which in turn creates more heat. With increased heat comes a higher burn level, which means more fuel is burned with every turn of the engine.

Be sure to use the correct oil made for your car. If you stick with the recommended grade, you may boost fuel efficiency by as much as two percent.

Clean out the air filter

When you get an oil change, clean or change out the air filter too. It’s a component that helps eliminate pollutants that may otherwise damage your engine. A dirty air filter doesn’t have the ability to filter out particles that can cause damage inside the system.

Change out the spark plugs

Spark plugs help ignite the fuel as it moves into the engine. If they stop working or misfire, you’ll lose out on efficiency. Most manufacturers recommend replacing them about every 30,000 miles.

Slow down

Americans have an addiction to speed. And while that may be a huge safety concern, it also impacts fuel efficiency.

Up to about 60 miles per hour, your vehicle will generally burn less fuel as it picks up speed. However, after 50 miles per hour, the drag starts to require more fuel to keep the vehicle moving. Studies show this can be as high as 25 cents a gallon for every 5 miles per hour you increase. If you drive a lot of highway miles, the savings from slowing down can add up over time.

How can you improve fuel efficiency?

One of the easiest ways to keep your car in top condition is to pull in for an inspection on a regular basis.

This will keep your car operating well. It also reduces your chance of being stranded away from home.

When was the last time you scheduled an inspection?

How Worn Out Shocks and Struts Can Cause An Accident

April 14, 2022 by Denver Express Car Care

How long can you drive on worn out shocks and struts? It depends. Like other parts on your vehicle, they rarely fail overnight. Instead, it’s a process where they gradually wear down, causing more problems with your drive. Eventually, their failure can lead to an accident.

But before shocks and struts fail, they start giving warning signals. That’s where you should start paying attention. This gives you ample warning, and provides you with enough time to get them replaced.

How shocks and struts work

Shocks and struts work as stabilizers. Every turn you make, every time you accelerate or step on the brakes, the shocks and struts work to keep your vehicle under control. Without shocks and struts, you would feel every bump in the road.

Today’s vehicles use shocks, struts, or a combination of the two. Though the two are often used interchangeably, there is a difference. Shocks are individual components of the suspension system, while struts are a structural component.

A shock absorbers job is to control the spring and suspension movement by converting kinetic energy into heat energy, and dissipating it through hydraulic fluid. All modern day shock absorbers are velocity sensitive, which means with faster movement comes more resistance. That allows the shock absorber to adjust to the varying road conditions. This protects you from bouncing, swaying, or diving as you stop and go in traffic.

How Worn Out Shocks and Struts Can Cause An Accident

A strut is a structural part of the suspension, taking the place of the control arm and upper ball joint of the conventional system. It’s lighter and takes up less space than a shock absorber. Struts provide the same damping function as shock absorbers. But they also provide structural support for the vehicle’s suspension. It supports the spring, and keeps the tire in alignment. It also bears the side load placed on the suspension. While struts also provide comfort and handling, they also are designed for wheel alignment and prevent wear on other parts of the suspension system.

How shocks and struts can cause an accident

Shocks and struts gradually wear out over time. You’ll start noticing a difference in the way your vehicle handles as you drive. If they fail, it can lead to an accident as you:

Drive over bumps and dips

If your shocks and struts aren’t working, you lose your ability to navigate. Bumps and dips can cause vibration, which may cause you to lose control over your vehicle. Taking a speed bump too fast may make it feel like your car is “flying.”

Steer around curves and turns

If your vehicle isn’t properly gripping the road, it can cause you to over or understeer, putting you in a dangerous situation.

Lose control over your brakes

Your shocks and struts and anti-lock braking system work together to help you drive. If your shocks and struts aren’t working, that passes into your braking system. If you’re driving along on a bumpy road, for example, you may lose control over your steering, and not have the ability to brake for other objects in your path.

Cause other parts to wear down faster

Your vehicle consists of 10,000 working parts, all coming together to help you stay comfortable and safe while you drive. If one part wears down and fails, it impacts every other part of the system. Shocks and struts can affect a variety of parts, including tires, brakes, and more. Following a regular maintenance schedule is the easiest way to ensure every component is working well to help you drive safely down the road.

What are the warning signs of failing shocks and struts?

Luckily, shocks and struts don’t wear down without warning. If you notice any of these warning signs, schedule an appointment with a mechanic as soon as possible.

You feel a constant up and down movement as you drive, especially at higher speeds. The movement may be slight, but once you notice it, it’s time for an inspection.
When you turn, you notice the vehicle leans to one side or the other. It feels wobbly as it completes the action for the turn.
The front end dives down as you brake, especially when you hard brake. You may feel like you need to apply more pressure to come to a complete stop.
The rear squats down as you accelerate as the front end rises, especially with hard acceleration.
You feel bouncing from the tires, especially as you hit a bump or dip in the road. It may bounce for some time, or produce a clunking noise as it bounces.
You notice unusual tire wear. This is because the tires aren’t fully connecting with the road.
You notice a fluid leak around the shocks and struts. This is a sign the seal is broken and it no longer can properly function.

Is it dangerous to drive with bad shocks and struts?

In short, the answer is: Yes.

Like other parts on your vehicle, each is installed for safety and functionality. If one part isn’t working correctly, it impacts all other parts within the system.

That’s why as the pilot of your vehicle, it’s important to pay attention to how your car drives. If your car feels unstable, or it tips to the side as you drive, or you feel it bouncing with acceleration or stopping, or you see any fluid leaks, it’s time to schedule an inspection.

Shocks and struts are sold and replaced in pairs. While it’s not required to replace the front and rear shocks or struts at the same time, it’s usually suggested. Because shocks and struts wear down at the same rate, if one pair needs replacing, the others won’t be far behind it. It’s easier to get them all replaced at the same time.

Is it time to replace your shocks and struts? Have you noticed a change in the way your vehicle drives?

Don’t wait for more problems to arise, Schedule your inspection today and keep your car in good working condition. Your comfort and safety may depend on it.

What It Means If Your Accelerator Sticks

April 10, 2022 by Denver Express Car Care

There are two things you rely on exclusively as you drive: your accelerator and your brakes. It’s a constant motion of applying pressure to one pedal and then the other as you move from point A to B.

In most cases, both work flawlessly. You tap, and they respond.

When an accelerator sticks, it can be a scary experience. While it doesn’t happen often, if the gas pedal sticks it’s both frightening and a dangerous situation. In an instant, the car jolts forward, accelerating without being responsive to the pressure you put on the brakes.

You don’t have time to think; you react. Your instincts will kick in. And the more knowledge you have about how acceleration and braking work, the better your response.

How an accelerator works

An accelerator controls how fast or slow your vehicle moves down the road. When you press the accelerator pedal towards the floor, it opens the throttle valve, which allows fuel to flow into the engine. This causes the vehicle to move faster.

Mechanically speaking, the accelerator is the controller of the fuel flow rate into the combustion chamber. The more you press down on the accelerator pedal, the more fuel is added to the combustion chamber, the more fuel is burned to power your car and move it into action.

While this process has experienced little change over the years, newer cars have built in safety sensors to help protect you as you drive. The accelerator pedal is wired with three sensors. If all sensors agree with one another, the car speeds and moves according to your actions. If any one sensor is off, it triggers a warning. If all sensors disagree, it places the engine in idle.

What causes an accelerator to stick?

The accelerator sticking could be caused by a variety of things.

If the floor mat rides up, it can become wedged underneath the accelerator pedal.
It may be from frictional wear of the braking mechanism.
Defective electronic controls may cause it to stick.
It could be electromagnetic interference somewhere in the system.

While this isn’t a common problem, it does happen from time to time. Would you know what to do if your accelerator sticks?

When an accelerator sticks

What It Means If Your Accelerator Sticks

It’s only natural to panic when something doesn’t work the way it’s supposed to. Yet remaining calm, cool, and collected is what’s needed to bring your vehicle to a stop. If the accelerator sticks, you should:

Stay calm

The first step is to move past the sudden feeling of panic. Take a deep breath, and realize you can fix this. There are workarounds, so it’s important to stay calm and work quickly to bring your car under control.

Shift to neutral

The most important thing to do is to decrease the car’s speed. To do so, shift your engine to neutral gear. This allows the engine to still rev, but it will cause the car’s speed to stop increasing. If you have a manual transmission, don’t forget to use the clutch as you shift gears.

Don’t play with the key or ignition button. You want to have access to your brakes, and control over the navigation system. This would take all power away.

If you can’t get the gears to shift to neutral, you should move to the side of the road, or out of traffic if possible. Apply your emergency brake to bring your vehicle to a stop.

Turn your hazard lights on

This is a signal to other drivers that there’s a potential problem with your vehicle. It brings instant awareness to whoever sees the hazard signals, and allows them to slow and give you plenty of room.

Apply the brakes

If you are able to shift to neutral, the next step is to apply your brakes. Do this slowly, monitoring the situation as you continue to slow down the car. Try not to pump the brakes, as this will deactivate the power brakes.

Navigate to the side of the road or other safe place

If possible, steer your car to a safe place away from other motorists. Give yourself plenty of room to be able to park, exit your car, and move to safety. Only then should you turn the ignition off and apply the emergency brake if possible.

Inspect your pedals

You can do a quick check to see if something is wedged under the pedal, causing it to stick. It may be the floor mat, or something smaller like a pen.

Call for help

If it’s not the floor mat or some other obstruction, it’s time to call for help. Tow your vehicle to a mechanic to have them assess the problem. Do not drive the vehicle until the situation is evaluated and the problem is fixed.

Maintenance to prevent accelerator problems

While a sticking accelerator can be caused by human error, it can also be from mechanical and electrical issues.

To prevent human error, ensure the inside of your car is clean and free of debris. Never allow anything to pile up on the driver’s side, especially near the pedals. Water bottles, purse straps, and office items like pens and paper clips should be kept off the driver’s side floor board. If you have a mat that isn’t form-fitting, it might be time to replace the mats.

Ice and snow can also impact the way the pedal works. On days where you’re in and out with ice and snow, water can accumulate and saturate certain types of mats. If it presses against the pedal mechanism, it can freeze the line.

While mechanical and electrical issues are rare, they can happen. It can be:

A malfunction with a component in the engine compartment
A defective vacuum hose
A faulty accelerator link

With regular inspections, a mechanic will test individual aspects of the system, and ensure all parts are working and in optimal condition. It’s the best way to ensure your vehicle is running, no matter what the conditions are like around you as you drive.

Have you ever experienced an accelerator sticking as you drive?

How Auto Mechanics Are Changing

March 7, 2022 by Denver Express Car Care

What car are you driving today? Does it run on gasoline? Is it a hybrid? Or electric?

Driving down the street shows just how far we’ve come in a short period of time. The hybrid car market is on track to grow at approximately 9 percent per year over the next few years. The electric car market has exceeded expectations, increasing 67 percent from 2019 to 2020.

Cars are changing. That also ensures that auto mechanics are changing too.

But what does that look like? Will you still be using mechanics in a similar fashion in the future?

Auto mechanics are changing. What does that mean for you?

Cars today

All you have to do is look in your own driveway or garage to see how cars are changing. You may have a gasoline-driven vehicle several years old, sitting next to a hybrid that gives you better gas mileage and is more efficient.

That’s representative of drivers all across America today.

Research shows more than 76 million vehicles on the road today are more than 16 years old. Thanks to technology, better mechanics, and economic considerations, cars over 12 years old are expected to grow as much as 12 percent per year. In the past decade, we’ve increased how long we own a car by 60 percent.

Hybrids and electric cars may be our future, but for now, we’re driving our cars longer than ever before.

Leasing or buying – a huge difference

Leasing is becoming a popular choice as cars increase in price. That means many drivers are out there swapping out their vehicles every few years.

That may seem like an easy way to move gasoline-based vehicles out and hybrid and electric vehicles in, but eventually, we’ll have a lot of older vehicles in all classes of cars.

Older cars run beyond their warranty. But they still have life left for the driver. That’s when auto mechanics will really change. Suddenly, we’ll have cars on the road – gasoline, hybrid, and electric – and they will all require maintenance to keep them running efficiently for the life of the vehicle.

Auto mechanics will be highly skilled as they move from vehicle to vehicle, keeping them in good operating condition. Not only will they be skilled with traditional mechanics, but they will also be skilled in electronics. That’s where independent shops will thrive as they continue to hone their skills to fix the problems associated with aging auto markets.

Auto parts

Have you faced this scenario? Your car isn’t operating correctly. It makes a noise, or you notice a smell. You bring it in for repair.

After a thorough diagnostics test, it’s determined one of the systems needs a new part. They order it … and you wait. Increasingly, you may have had to wait days for a part to be shipped in from somewhere else. It takes time for the part to be delivered, and more time for the part to be installed.

One of the advantages of having a standard car with an equally common problem is the abundance of parts. You can find them everywhere.

With so few hybrids and electric vehicles on the market, finding specific parts can be challenging at best.

As cars grow in popularity and we start honing in on simplifying how different systems work, even parts on hybrids and electric vehicles will become more commonplace. Especially for independent shops, they can be very specific in the services they provide, and be ready to make the necessary repairs quickly when you drive in.

That saves you time and money in the long run.

The future of auto repair

You only have to step into an auto mechanic shop today to see the changes that have taken place over the past few years. It’s more about diagnostics and technology than good old-fashioned “grease monkey” discovery.

The world is being automated right before our eyes. Why should we expect any difference within the automotive repair industry? Yes, some parts and services of the auto mechanics niche will disappear forever – hello, buggy whips. But new parts and services will take their place.

As we build more sophistication into every car we develop, that means an increase in artificial intelligence (AI), machine learning, and technology. All of this operates with sensors and other sophisticated equipment. When something goes wrong, it will be the auto mechanic of the future that steps in and makes the repair.

There will also be distinctions between individual and commercial classifications. As we step into autonomous transportation, there will be even more need for regular maintenance to ensure all vehicles on the road stay in good working condition. To ensure vehicles operate well to avoid error and reduce driver error, it will be imperative that every technical part on a vehicle is calibrated and working well.

That requires a skilled auto mechanic to ensure it’s fully operational.

Different time. Different vehicle. Different skills.

Auto mechanics are changing

But the need will never disappear.

Just like the Ford Model T required a specific type of auto mechanic, so to will the cars of tomorrow.

No matter how many technological advancements we make, or how many changes we make to the vehicles we drive, there will always be a need to maintain them, and keep them functioning at their best.

Every part, component, electrical connection, or mechanical device will wear down over time.

It’s an auto mechanics’ job to understand each system thoroughly, and be able to fix it when it needs to be updated.

The complexity of the systems are changing. An auto mechanic’s job will change too.

It won’t decrease the need for auto mechanics. It simply changes the services they provide.

What matters most is the relationship you develop, and the trust you place in ensuring they do a top-quality job for you.

Are you happy with the auto mechanic who services your vehicle?

Does Your Car Really Need a Power Steering Flush?

February 28, 2022 by Denver Express Car Care

Have you ever brought your car in for something simple – an oil change – and the mechanic approaches you with a list of potential parts and services it needs to run properly?

It can be confusing at best.

Does your car need fluid flushes or full detailing to ensure an efficient ride? Or is this just a way for the mechanic to bring in extra money?

We get it. It seems as if every company is fighting for ways to add on sales, and bring in extra money.

And flushes can be confusing. Let’s take a power steering flush as an example. You know your car uses power steering to make it easy to drive. You may have a general understanding of mechanics, knowing it takes power steering fluid to ensure movement as you go. How does the fluid get there? And will it wear down? How do you know?

Great questions! Let’s find out.

Start with understanding the power steering system

Power steering is a system that uses engine power to control the front wheels effortlessly. It makes it easy to maneuver at lower speeds, making it easy to take tight corners, and turn into spaces like parking spots and enter garages. Without it, you’d need a lot more force to keep control over your vehicle, especially as you turn and move in different directions.

Today’s vehicles use one of three power steering systems: hydraulic, electric, or hybrid electro-hydraulic. Each utilizes the same function, even if they approach it differently.

Does Your Car Really Need a Power Steering Flush?

The oldest – hydraulic power steering – has been assisting drivers for more than 50 years. It utilizes a hydraulic pump assembly that pushes transmission fluid into the steering assembly, which aids in controlling the tires. The pump draws power from the engine to perform its work. Because it remains operational while the vehicle is running, it exerts wasted energy while moving on a straight stretch of road.

Hydraulic power steering relies on several different types of power steering fluid.

Automatic transmission fluid (ATF)
Synthetic power steering fluid – these are engineered for specific types of cars
Non-synthetic power steering fluid – mineral fluid that often is used in place of ATF

Like other fluid types, it’s important to know which your car accepts to reduce the chance of damage, and give your car what it was designed with.

Electric power steering (EPS) is becoming the new norm for today’s vehicles. Instead of a hydraulic pump, the gear connects to an electric motor and a control module, which uses sensors to determine how much assistance is needed to the steering system while you drive.

Electro-Hydraulic steering is a hybrid of the two. It provides the smooth feel of a hydraulic system, with the energy draw of the electric system. It improves fuel economy as the pump only operates when you need assistance. This is most common in heavy commercial vehicles, though some car manufacturers install them because of the benefits.

My car uses power steering fluid – do I need a flush?

If you use hydraulic power steering fluid, you may wish to speak with a mechanic about the benefits of having the steering pump flushed and filled with fresh fluid. It pays to know what your manufacturer suggests, as well as understand what your mechanic finds to make this suggestion.

While it isn’t a common maintenance item, it isn’t something you can ignore. Paying attention to what’s happening under the hood can give you assurance everything is in good working condition.

Power steering fluid is red, and is often similar in color to coolant (if your coolant is red.) It can turn a deeper shade over time. Color alone isn’t a sign that something is wrong. It takes further investigation.

If you notice a leak, find out where it’s coming from. Over time, seals, o-rings, and other parts can deteriorate and result in a leak. Fluid underneath your car in conjunction with problems with your power steering could be an indicator it’s time for a power steering flush and repair work.

Many reservoirs are installed with see-through plastic so you can track how much fluid you have, and check to ensure it’s not running low. Your owner’s manual will guide you to where it’s located on your vehicle.

What a power steering flush will do for your vehicle

Is a power steering flush really needed? There are a few important things this service can provide you with.

Better steering – if you notice your driving is becoming more difficult, it may be a sign of compromised power steering fluid. New fluid will get rid of the grime, and make your drive that much safer.
Protects the pump – fluid is the life-blood to any major component. Replacing power steering fluid is much less expensive than risking damage to larger items like the power steering pump.
It flushes harmful contaminants – driving here in Colorado means you’re subjected to everything on the road. Mag-chloride and salt in the winter, mud and other debris in the summer as the rains set in. flushing the system pushes these harmful contaminants out.
Peace of mind – keeping the maintenance items recommended in your owner’s manual on your calendar can give you peace of mind over time. Instead of waiting for a major breakdown, being proactive can keep your vehicle in the best working condition possible.

Is it time for a power steering flush?

Before you head out on your next road trip, or move into a new season, head in for an inspection to keep your vehicle operating well.

By working with our mechanics, we can help you determine how to keep your car in good working condition.

CV Joint and CV Boot Repair – What You Need To Know

February 18, 2022 by Denver Express Car Care

“Your tire is flat. You’ll need to replace it.” Those words are straightforward and simple to understand. As a driver, if a mechanic gives you that advice, you may jump right on board.

But some parts are a little more difficult to understand.

“Your CV joint and CV boot are damaged and need repair.” Where do you begin?

What are a CV joint and CV boot?

CV stands for constant velocity. A CV joint (or CV axle) is used in front-wheel drive vehicles to transfer engine power to the drive wheels. It’s also used in some vehicles with independent rear suspension, as well as some four-wheel and all-wheel drive cars.

A CV axle uses two CV joints (an inner and outer joint) to transfer power to the drive wheels at a constant speed no matter what the travel conditions. That means no matter what speed the vehicle is traveling at, or the state of the road, the CV joint handles the power to ensure a safe and comfortable drive.

CV joints use grease for lubrication. To keep this grease pliable and in good working condition, the CV joints are covered with a rubber boot called a CV boot. CV boots are made from durable rubber designed to withstand extreme temperatures and driving conditions. CV boots are designed to last 100,000 miles or more. But because they are often exposed to the elements, they can and will occasionally go bad. Like other parts on a vehicle, it’s a good idea to routinely inspect CV boots to ensure they are in good working condition. If you move beyond 125,000 miles, scheduling routine inspections will ensure they stay operational and don’t leave you stranded.

How CV joints can fail

CV axles rarely fail. CV joints, however, can occasionally fail if something happens to the CV boot. When a CV boot is torn or fails due to age, the grease inside keeping the CV joints well lubricated starts to leak. It also leaves the CV joints unprotected, meaning dirt, grime, and other debris from the roadway can enter the joint. When this happens, it will eventually fail.

CV Joint and CV Boot Repair - What You Need To Know

Of the two, the outer joint will almost always fail first. That’s because more of the action is performed using this joint, and it’s also more vulnerable to the open road. If you suspect damage to the CV joints, it’s almost always the outer joint.

How CV boots can fail

If the CV boot gives out, it puts the CV joints in danger. Ensuring the CV boot is in good working condition can prevent most costly problems. CV boots can give off several warning signs of a problem:

Grease leak – it’s the most common symptom of a CV boot issue. Over time, the rubber can become dry, brittle, or crack. Once a split occurs in the rubber, grease from the CV joint can leak out. You’ll see this on the inside of the wheel, or flung onto the chassis or other parts of the underside of the vehicle as the CV joint continues to turn.

Clicking, popping, or grinding noise – if a CV boot is damaged for a while, it can lead to a CV joint becoming loose on the axle. If you hear a noise during turns, this might be the case. Most CV joints that reach this stage need replacing.

Vibrations – if a CV boot is damaged, it can allow dirt, grime, and other particles to get underneath the boot and near the CV axle. This debris causes damage, which can lead to a vibration up from the CV axle and through the steering wheel. This may only happen at certain speeds.

A CV boot is a protection device to keep the CV axle and CV joint clean and damage-free. It’s the first line of defense. To ensure a long life, keep an eye on the CV boot for potential damage, and maintain and repair it at the first sign of wear.

Inspecting the CV Axle

Whenever you suspect a problem with your vehicle, the fastest way to ensure everything is working well is to bring it in for an inspection. Trust our knowledge and experience to ensure your car is working well and won’t leave you stranded.

If you do suspect a potential problem with your CV axle, you can do a manual check at home with just a simple flashlight in hand.

First, park your car on level ground. Ensure the emergency brake is engaged.

Next, slide underneath the vehicle at front center, to be able to inspect both CV axles at the same time. Alternatively, you can slide underneath in front of one wheel at a time and inspect them separately.

Look closely at each CV axle. Each axle has two CV boots – outer and inner. Visually inspect the rubber for cracks, leaks, or other damage. If you see grease leaking, it’s a sign of wear.

If you suspect CV joint damage, you can take your vehicle out for a drive, paying attention to the way it drives. On a flat surface, such as an empty parking lot, turn the steering wheel all the way in one direction, then drive in a circle. Repeat going the opposite direction. If one of the CV joints is bad, you’ll notice a clicking or popping sound as you drive in a circle.

If the CV joint is bad enough for you to hear a clicking or popping sound while driving straight, it’s reached the end of life, and will ultimately fail soon. Schedule an appointment as soon as possible to avoid further damage, or risk being stranded by the edge of the road.

Does your vehicle need CV joint or CV boot repair?

CV boots serve as a protection device to allow the CV axles and joints to remain clean and in good working condition. To maintain a long service life, inspecting them at the first sign of potential damage is important. When in doubt, have a professional check it out. Make an appointment today.

Does Your Clutch Need Repair or Replacing?

February 10, 2022 by Denver Express Car Care

Clutch failure. Even if you aren’t quite sure what it means, it sounds bad.

Like other parts of your vehicle, the clutch is only designed to last for so long before it starts to wear down. Both manual and automatic transmissions have clutches designed to engage the transmission and harness the power to move the wheels throughout a full cycle. As you move out of park and start moving, the clutch engages. As you come to a stop, the clutch engages.

Manual transmission vehicles create movement between gears manually using a clutch pedal. An automatic transmission creates this movement automatically. In both cases, there is constant movement and friction as the gears move into place. Over time, enough wear will occur to wear down the clutch, requiring repair or replacement to ensure your safety.

How do you know which it is? Is it time to repair or replace the clutch in your car? Read on to find out how you’ll recognize the symptoms.

What is a clutch? Why does my car need a clutch?

Before you can diagnose clutch problems, learning more about its function can help you recognize potential problems early.

A clutch is a mechanical device that engages and disengages the transmission between several rotating shafts. A clutch is a connection point between two shafts, allowing them to lock and spin together, or disengage to operate separately.

In most vehicles, the clutch sits between the engine and the main driveshaft. It takes power from the engine and transfers it to the wheels. While an engine spins and creates power continuously, your wheels don’t. To gain control over the wheels without turning off the engine, you need a way to operate the two separately. This happens between the clutch disc and the engine’s flywheel, giving you full access to control power and speed in any condition.

Does Your Clutch Need Repair or Replacing?

A traditional clutch will contain a variety of parts, including:

Clutch disc – the connection point to the transmission
Cable – connects the clutch pedal to the clutch fork
Clutch fork – controls the force between the clutch and the pressure plate
Pressure plate – connects to the clutch disc
Flywheel – connects to the engine

Each piece is connected via links, cables, and other bearings to ensure it maneuvers correctly. If any one of these parts starts to fail, you’ll notice it in the way your car performs. A few things that can go wrong include:

A slipping clutch

A clutch can have anywhere from 50,000 to 100,000 miles before it needs repair or replacement. As the clutch wears down, the material begins to wear out, and it won’t perform as it did when it was new. A clutch needs friction to engage. Without the proper friction, the clutch won’t work as well as it should. That means you may feel the clutch slip as you accelerate, and the clutch moves between gears. It’ll feel like your vehicle is dragging, even though the engine may be revving up.

A slipping clutch can be caused by a variety of problems, including:

A cable that needs adjusting
A clutch linkage is bent or damaged
The pressure plate is weak or warped
The clutch assembly is dirty from oil or grease leaks
A broken motor mount

As it slips between gears, it may also become sensitive to movement, or even get stuck. For a manual transmission, you may notice this if you press down on the clutch pedal and it slips out of gear immediately, or you have to push it all the way to the floor without movement. Clutches can stick for various reasons, including:

A broken or stretched clutch cable
Leaky or defective clutch master cylinder
Air in the hydraulic line
Clutch components out of sync
Linkage out of adjustment

A clutch master cylinder failure

Clutch failure can originate in the clutch master cylinder for a variety of reasons. With each potential problem, it creates signs that something is wrong. You’ll notice a problem in different ways.

Noises – when parts aren’t properly synced and working well, the friction between the parts will create a variety of sounds. With a manual transmission, you might hear a noise as you press the clutch pedal to the floor, even if the engine is turned off. That’s an indicator of a clutch fork problem. As lubricant dries up, it can cause a noise as it tries to engage.

Vibrations – as you press down on the pedal, you may feel a vibrating sensation from time to time. Vibration can be caused by a variety of things, but usually starts as things wear down. Friction no longer occurs between separate parts, meaning they rub against each other incorrectly. This appears as a vibration as they try to engage.

Spongy or loose feel – this is often caused by a hydraulic problem. There may be air in the hydraulic system, low fluid in the reservoir, or a leaking connection, hose, or pipe somewhere in the system.

Grinding while shifting gears – there should always be free-flow as your car moves from gear to gear. When you start feeling or hearing the process, it’s a sign of a worn down part. Any one of the parts that make up the clutch system isn’t moving correctly at the right speed. Instead of moving into position, it sticks or drops quickly. You’ll hear it as parts don’t connect as intended. It may require an adjustment, or a full replacement.

What can it be? An inspection will get to the root cause

Each symptom is a signal it’s time to bring your car in for an inspection. It’s the easiest way to get to the root of the problem, and fix it before it escalates into something else. In some cases, it might be a simple repair. It’s better to know for sure before it escalates, causing more damage, and potentially putting you at risk.

Does Your Car Really Need a Transmission Flush?

February 7, 2022 by Denver Express Car Care

Some vehicle maintenance items become so routine, you rarely think about them. You fill up with gas, pull in for oil changes, and replace your tires when the tread wears down.

But internal items are trickier to understand. How do you know if your transmission isn’t operating well? Would a transmission flush work, or is the problem deeper?

A quick search online will tell you controversy surrounds transmission flushes. Some reports say it’s a myth to need to flush the system at all. Other resources tell you it’s a must to keep your car in good working condition. Who do you believe?

A quick search by brand tells you it’s mixed between manufacturers. Toyota recommends automatics flush the system every 60,000 to 100,000 miles, while manual vehicles need care every 30,000 to 60,000 miles. Mercedes has a wider range of recommendations, depending on the year, make, and model. You’ll find advice for transmission flushing between 40,000 and 100,000 miles.

Understanding automatic transmission fluid

According to a CarMax study, Americans love automatic transmissions, with 96 percent of the population driving automatic vehicles. Maybe it’s our multitasking strategies that make automatic transmissions more convenient.

Automatic transmissions use a hydraulic system that relies on a constant flow of transmission fluid to provide the correct supply of hydraulic pressure for ultimate response. It’s the transmission fluid’s job to provide proper flow through each hydraulic line within the transmission system.

Does Your Car Really Need a Transmission Flush?

Transmission fluid is designed with a specific viscosity and additives that help reduce expansion as the fluid heats under pressure. If operating well, it will remain consistent over time.

Over the years, the additives will wear down, which can cause the fluid to thin and be more susceptible to the expansion process. This is when it’s time to replace the transmission fluid to ensure your car continues to operate well.

Why a transmission flush is necessary

Today’s vehicles use a variety of fluids to continue to operate well:

Windshield washer fluid – to ensure your safety while driving on dirty roads
Motor oil – to keep the engine healthy and running smoothly
Coolant – also known as antifreeze, helps to keep the engine cool
Brake fluid – keeps the brake system fully operational

Each of these fluids is important to ensure your vehicle continues to operate, and you won’t be stranded while out on the road.

Some fluids drain out of the system and simply need to be refilled to continue working. Windshield washer fluid provides the necessary spray to keep your windshield clean in all driving conditions. If it runs out, you simply fill up the reservoir and it’s available once again.

Transmission fluid works slightly differently.

With an automatic transmission, the fluid continues to circulate throughout the fuel lines. As it wears down, small particles travel with the fluid, and can stick or corrode the inside of the lines. Even if you were to drain the lines, those tiny particles could still be a problem. The only way to thoroughly remove those particles is with a flush to the system.

If those particles continue to build, they can wear down the various parts of the transmission system. Here are four reasons why it’s important to perform a transmission flush according to manufacturer’s guidelines:

It increases transmission lifespan

Clogs in the hydraulic fuel lines can lead to all kinds of problems. As particles and contaminants build up, they can lead to inner seal leaks and breaks. It can force liquid into areas where it shouldn’t be. And while you might not notice the results immediately, they can have a trickle down effect. Flushing the transmission occasionally and replacing minor parts is a lot more friendly on the wallet than replacing a transmission after complete failure. A transmission flush can extend the life of your vehicle by ensuring the entire system is once again operating properly.

It makes shifting easier

It’s the transmission’s job to ensure smooth shifting as you speed up and slow down. Over time, particles and contaminants can cause gears to slip or stick, impacting the effectiveness of your driving. A transmission flush gets rid of those imperfections and ensures a smoother shift.

It improves fuels economy

How well the transmission operates is what ultimately controls fuel efficiency. If the flow of gasoline is inhibited in any way, it takes more energy to produce the same results. A vehicle in good working condition ensures the best fuel efficiency possible. If the transmission slips or doesn’t engage properly, it requires more fuel inside the engine. A transmission flush brings the entire system back to good working condition, helping your car be as efficient as possible.

It protects your car’s warranty

Do you have an extended warranty on your vehicle? More manufacturers are offering years of coverage on well cared for parts. The key is ensuring each system is well cared for, and that you meet their key requirements. Do you know what your owner’s manual says about transmission flushes? If not, it’s time to read up and learn what your vehicle needs to thrive and stay within the acceptable guidelines. Be sure to track it in case you need to fall back on the warranty at any point you own the vehicle.

Is it time for a transmission flush?

A lot of what we’ve referred to in this article concerns automatic transmissions. Manual transmissions work differently, and require different levels of maintenance. The best way to ensure you’re giving your vehicle what it needs to operate well is to refer to your owner’s manual regularly, and use the advice to set up your own maintenance routine.

Does your vehicle need a transmission flush?

Do All Shocks and Struts Need To Be Replaced At The Same Time?

February 3, 2022 by Denver Express Car Care

Describe your vehicle’s performance. Most people would say things about the power it has when driving on the road.

But there’s another side of performance that determines just how enjoyable the ride is.

If you’ve ever ridden in an old pickup truck, imagine how bumpy the ride was as you rambled down the road. Every bump, every pothole shot right through your system.

Now think about the ride in a high performance car. You barely heard the road. You definitely didn’t feel it. Every bump was handled with ease, barely registering on your radar.

You can thank the shocks and struts in your vehicle for that.

What’s the difference between a shock and strut?

Shocks and struts are often used interchangeably. Yet they have distinct differences. You can not substitute one for the other. If your vehicle uses struts, you cannot replace them with shocks.

A shock is the piece of the suspension system that helps coil springs absorb the impact of the road. It’s the shock’s job to take the bounce out of the movement of the car. They help keep the tires fully connected with the road instead of bouncing up as it hits different bumps in the road.

A strut combines a shock absorber and the coil spring into one single unit. While it acts as an absorber with every bump your car hits, it also provides structural support and integrity to the suspension system.

What does your vehicle use, shocks or struts?

Each wheel will either have a shock or a strut. They come in pairs. If your rear left wheel has a shock, your rear right wheel will too.

However, your vehicle may have shocks on one axle, and struts on another. Most modern vehicles have struts on the front axle, and shocks on the rear axle. You might also find struts on both axles, while it’s rare to have shocks on all four.

What does your car use?

Check your owner’s manual. If you no longer have it, a quick check online will determine what your make and model have in place.

Do All Shocks and Struts Need To Be Replaced At The Same Time?

You can also check under the car. They are easily seen if you look underneath your vehicle.

A mechanic can also tell you which components are attached to your suspension system. They can also make recommendations for replacement, when necessary.

Do shocks and struts need to be replaced at the same time?

We alluded to the answer above. Shocks and struts come in pairs. What’s located on one side of the axle will appear on the other.

Shocks and struts are always sold in pairs, and should be replaced in pairs. This provides consistency to both sides of the vehicle.

What’s more, mechanics suggest that you replace all four at the same time. This gives you a consistent response on your vehicle overall, every single bump you hit in the road.

If one set of shocks or struts wears out, chances are the other set isn’t far behind. By replacing them all at the same time, you ensure a safer, more comfortable ride.

How do you know when your shocks and struts need replacing?

Shocks and struts tend to wear out every 50,000 to 100,000 miles. The more aggressive you are on the road, the faster they will wear out. If you frequently drive on dirt roads, and love taking advantage of mountain driving, you’re more likely to replace them sooner rather than later.

Like other components, shocks and struts don’t wear out all at once. Instead, they provide warning signs of potential problems.

Bumpy ride

It might start gradually, but you’ll eventually notice your ride is getting rougher. You start to feel every bump in the road. Does your vehicle bounce more than once or twice when you hit a bump? Let it go on too long, and you’ll feel like you could lose control.

Fluid leak

Whenever you notice leaking fluid, it’s a sign to bring the car in for inspection. Leaking fluid near the exterior of the shocks and struts is a sign they’ve been compromised and they no longer have enough hydraulic fluid to do their job. If you aren’t sure if the fluid is coming from the shock absorber, wipe it down and check it again in a few miles.

Uneven tread wear

Take a look at your tire tread from time to time. It can tell you a lot about performance. If you notice wavy dips on the tread, it’s a sign you have worn shocks and struts. This is caused when the tires don’t stay firmly on the road as you drive. Instead, they bounce up from time to time, which creates uneven wear marks. This will compromise your tires faster, and decrease your stopping power.

Braking problems

A classic sign of worn out brakes and struts includes a nosedive when you hit the brakes, or swaying as you make a turn. Because the shocks and struts aren’t able to handle the changes in your vehicle’s weight distribution effectively, your car will decrease in performance.

Today’s vehicles are designed with a variety of safety systems built into the structure. Anti-lock brakes and stability control systems all rely on the various components to keep your car safe. If any piece isn’t functioning properly, it puts the entire structure at risk. Response is everything in an emergency.

The best way to know when it’s time to replace your shocks and struts is to let a technician evaluate your suspension from time to time. If you notice a sign, book your appointment sooner rather than later. Also consider creating inspection appointments at the change of seasons. This is a great way to ensure your vehicle is ready for the ice and snow of winter, and the heat of the summer.

After any suspension work, it’s a good idea for a full alignment too. This ensures your car is balanced and ready for all the driving you’ll do in the coming weeks and months.

When was the last time you had your suspension system checked? Shocks and struts need to be replaced in pairs, especially when you notice problems. If you suspect an issue, give us a call today.
