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.

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.

How Long Should a Car Battery Last

January 7, 2022 by Denver Express Car Care

Without a car battery, your engine wouldn’t start, and you’d be stuck where you are.

Of course, your car battery does more than start the vehicle. It also creates the power necessary for both the ignition and electrical systems. Think of your battery as your car’s lifeline. Without it, your car won’t function.

How long should a car battery last?

How a battery works

A lot of things around your home run off of battery power. From your smartphone to a smoke detector, batteries ensure you have enough power to the device to make it function.

When you turn the key in the ignition, it’s the car battery that provides the jolt of power needed to power up the electrical components in your vehicle. The car battery converts chemical energy into electrical energy, and provides enough force to send voltage to the starter. It also provides a steady stream of electrical current to stabilize this energy and keep the engine running.

That’s a lot of work for one little box underneath the hood of your car.

Depending on the make and manufacturer, a car battery is designed to last anywhere from 3 to 5 years. How long your battery will last depends on things like:

Driving habits

Short trips of 20 minutes or less can actually shorten the lifespan of your car battery. Each time you start your car, it uses battery power. When you make short trips around your community, it doesn’t give the charging system enough time to fully recharge the battery. By integrating short and longer trips throughout the day, it works to keep your car battery healthy and in good working condition.

Don’t think that leaving your car parked for extended periods of time won’t impact the battery. They naturally self-discharge over time. It’s better to disconnect the battery and remove it, or use a trickle charger designed to keep the battery at a constant charge level as it sits.

Also be wary of allowing your car battery to completely wear down through the use of electronics. Various car accessories like headlamps, interior lights, and the radio drain power from the car battery. That’s why if you forget to turn the lights off, it can impact your car starting the following day. Avoid using accessories for extended periods if you aren’t operating your car.

Weather

Here in Colorado, we can have widely changing temperatures within a short period of time. Throughout the year, your car may deal with below zero temperatures, followed by heatwaves in the triple digits in the summertime. That’s a lot for your batter to deal with.

Protecting your car battery from these extreme fluctuations will extend its life. If you have a garage, keeping your car inside during extreme weather will protect the battery from deterioration.

Maintenance

If you pop the hood and look underneath, you may discover corrosion around the battery box. Corroded batteries weaken the battery’s charge, which can impact its lifespan. You can keep corrosion at a minimum by scrubbing it with a mixture of baking soda and water, then wiping away the residue including dirt or grease.

Batteries won’t go bad overnight. By regularly testing it, you can watch how much amperage it’s putting out. We can test it when you come in for regular maintenance to ensure it’s operating well.

Is your car telling you it’s time for a new battery?

While you can give your car battery a long lifespan with proper maintenance and paying attention to your driving conditions, eventually it will wear out. It doesn’t suddenly fail without warning signs first.

Corrosion

When you see corrosion building up around the positive and negative battery terminals, it’s a sign the battery is weakening. You can clean it, but be aware it’s showing signs of age.

Slow engine crank

When your battery is working well, your car should gain power immediately upon turning the key. If it’s slow to react, that’s a sign your battery is weak.

Check engine or battery light

Today’s technology is designed to warn you of potential problems long before they cause you an issue. At the first sign of a dashboard light, bring your car in so we can use diagnostic tools to determine what’s wrong with your vehicle.

Bloated battery case

Swelling usually happens when the battery has overcharged. Heat and hydrogen gas build up faster than the battery dissipates, which can lead to the battery casing warping and expanding.

Leaks

When a car battery leaks, it can be from several things. Leaks can form through the cell caps at the top of the battery, or through damage to the battery body. Overcharging can also damage the battery, or if it is subjected to extreme cold for a length of time. This may be noticeable from the rotten egg smell it produces.

Low battery fluid

While not a regular maintenance item, your car battery can run low on fluid. As a battery recharges, electricity flows through the water as it’s converted from original gasses of hydrogen and oxygen. This can sometimes lead to water loss, which will need to be replenished to keep it in good working condition.

Age

The older your battery is, the greater chance it has of not working at its best.

If you’re not sure how old your battery is, there’s an easy way to tell. It has a creation date printed on it. This creation date is listed as a code with a letter and number. The letter corresponds to a month – A is January, B is February, and so on. The number gives you the final digit of the year – 8 would be 2018, 9 would be 2019, etc.

If your battery is more than four years old, it’s a good idea to plan on replacing it soon to avoid future issues associated with a weak battery. This gives you a chance to replace the car battery on your time rather than deal with an emergency situation somewhere away from home.

If you’re having battery problems, bring your car in and let one of our technicians test it to find out where the issue lies. We can service it as necessary, or suggest a new battery that will ensure your car’s safety.

Does Your Hybrid Vehicle Need an Oil Change?

January 4, 2022 by Denver Express Car Care

It’s hard not to notice there are more electric and hybrid vehicles on the road now than ever before. Maybe you’re thinking of switching and investing in new hybrid technology. But what will that do to your maintenance routine? Do hybrid vehicles still need an oil change?

Before we get into maintenance, let’s dive into the statistics.

The different types of electric vehicles include:

Hybrid electric vehicles (HEV) – they are powered by traditional gasoline and an electric motor that uses energy stored in a battery. The battery is charged by regenerative braking as you drive.

Plug-in hybrid electric vehicles (PHEV) – they are similar to HEVs but rely on plugging in to recharge the battery.

All-electric vehicles (EV) – these run on electricity alone.

While all-electric vehicles are growing in popularity, hybrids have been on the market longer, and continue to have higher sales. Currently over 5.4 million hybrid cars have been sold, and are on the roads all across America.

Does Your Hybrid Vehicle Need an Oil Change?

If you own one or are thinking of buying one, what does that mean for your regular maintenance routine?

Do hybrids need an oil change?

Hybrid vehicles run on both gasoline and electricity. While this increases the gas mileage, and ensures you won’t use as much gas as with more traditional cars, it still works in the same manner. A hybrid vehicle still relies on a combustible engine for part of the process, meaning you’ll still need to include oil changes as a part of your normal maintenance routine.

The good news is you can stretch out the time between visits. Just like you’ll find your gasoline goes farther, so will your motor oil. The typical hybrid manufacturer suggests you can go 10,000 miles or more between oil changes, more depending on how you drive. Check with your owner’s manual to see what your manufacturer suggests.

Keep in mind that a combustion engine will always need regular oil changes to continue to operate well. If you drive your hybrid only short distances, it may push the mileage beyond a year or more. Just like traditional vehicles, you should change the oil regularly based on mileage or age, ensuring the motor always has fresh oil to keep it working at its best.

Manufacturers will also recommend specific types of motor oil. Because a hybrid still uses a combustible engine, you can schedule an oil change like you would with a traditional car.

What about other hybrid maintenance items?

Hybrids have special needs. Because they are essentially two cars in one, it’s important to understand the different types of maintenance it will need over time.

Because it runs off a combustible engine, it will need much of the standard care, including:

Oil changes – while using a battery for some of the power will put less strain on the engine, it will still need regular oil changes.
Tires – adjustments, rotations, filling, and replacement will all be standard care for hybrids.
Filters – because it has the inner workings of a combustion engine, it will still need air filters and cabin filters as a part of your normal care routine.
Fluid refills and flushes – vehicles require many different types of fluids to stay running smoothly. To ensure levels remain constant, and you maintain and flush them for refills at the required intervals, be sure to check with your owner’s manual and work with a mechanic who can provide proper maintenance for as long as you own your vehicle.

Hybrids still use a braking system, however, they rely on regenerative brakes for full operation. As you brake, the energy is absorbed back into your battery to keep it fully charged. As a result, these brakes need special requirements to keep them working at their best. Be sure a mechanic understands the nuances and can provide you with expert care.

One of the biggest differences is with the car battery. Hybrid batteries must be powerful enough to provide as much energy as fuel gives gasoline vehicles. This means they are larger capacity than traditional car batteries, and have special needs. You can’t purchase a traditional battery and expect it to do the same job. However, hybrid batteries tend to last much longer than in a fuel-based car. Some manufacturers offer up to a 150,000 mile warranty. Just be sure to understand the nuances of the warranty, and follow the specific guidelines to ensure you don’t void it by not following the rules.

Because a hybrid vehicle runs on both fuel and electricity, you’ll find it has a complex electrical system that should be maintained over time. They are built with auto start and shut off features that help with fuel economy, and to preserve the life of the battery. The electrical system should be calibrated periodically to ensure it provides proper power within the system. Too much power or a jolt of electric current could cause serious damage to your starter or transmission.

Schedule care for your hybrid

Above all, your hybrid vehicle requires regular routine maintenance to ensure it keeps running and in good condition. Don’t wait until you have a problem. Instead, schedule regular maintenance to ensure you catch potential problems before they grow into bigger issues.

A great place to start is by giving your hybrid vehicle an oil change. Because a hybrid relies on a standard combustible engine, it uses standard motor oil built for all combustible vehicles. Just be sure to check with the manufacturer for guidelines on what oil to use.

Finding a mechanic with a routine maintenance item like an oil change is a great way to find a mechanic who treats you fairly, and gives you a chance to discover someone in your local community who you can rely on to do the job correctly.

Having Steering Problems? It’s Probably One Of These Things

December 18, 2021 by Denver Express Car Care

Power steering is something most drivers take for granted. Until they have steering problems.

Modern vehicles all use power steering to make driving easier. If you’re under the age of 40, chances are you’ve never driven anything without power steering. Cars today use a hydraulic power steering pump that provides help while you steer.

Go back in time to when cars entered the marketplace. Cars were built so the driver controlled the moving process. When a driver wanted to turn right or left, they would have to crank the steering wheel and physically adjust the wheels to get the car to move in their desired direction. That required physical strength that some people had trouble with. Inventors set out on a course to make the process easier. By the 1960s, power steering was an option for most vehicles, with it becoming standard by the 1970s.

Of course, a lot has changed over the years.

How power steering works

Today’s vehicles use power steering to respond to even the smallest of adjustments you make. That makes it easier to control, and easier to stay in the lane as you drive, no matter what your speed.

Power steering systems use either an electric or hydraulic device to turn and steer the wheels.

Hydraulic power steering uses hydraulic fluid to amplify the action of turning the wheels. Hydraulic fluid is pressurized by a pump driven by the engine, which provides hydraulic pressure for the steering system. As you turn the steering wheel, hydraulic pressure is applied to the steering gear, which makes it easy for the wheels to turn.

Having Steering Problems? It’s Probably One Of These Things

Electric power steering uses an electric motor that draws energy from the electrical system to provide steering ability. As a driver adjusts the steering wheel, sensors detect movement. This data is fed into a computer system which evaluates how much assistance to apply. The biggest benefit of an electric power steering system over a hydraulic system is better adaptation to specific driving conditions.

Electronic power steering, also known as EPS, is growing in popularity because of the performance improvements. Electric steering can give the driver the option to switch between different driving conditions for a different experience in driving. Comfort, standard, sport – you’ll find these steering systems and more depending on the make and model you drive.

Common power steering problems

Today’s vehicles have over 10,000 parts. Two main power components with the steering system include the pump, and the rack and pinion unit. It also includes a variety of hoses and connectors to ensure the system works well. If there is an issue with any of these parts, you won’t get assistance as you turn the steering wheel, making it difficult at best. That can put you in danger as you respond to actions out on the road. In general, five things may be wrong with your vehicle if you’re having trouble turning the steering wheel.

Low power steering fluid

One of the most common reasons for decreasing power in the steering wheel is low power steering fluid within the system. This usually occurs when the fluid is leaking from the pressurized hoses. If the hose is cracked or wiggles loose, it can cause the fluid to leak out. This fluid is required to keep the entire system well lubricated. If there isn’t hydraulic fluid within the system, the steering wheel gets more difficult to turn. You might be able to drive it, but it is a sign of a problem within the system. Eventually the steering pump will fail, and replacement is a lot more expensive than adding in new power steering fluid.

Bad power steering fluid

Parts and systems today are designed for years of use. But that doesn’t prevent fluids from getting old and stopping working. Even if hoses and joints are still in good shape, holding power steering fluid inside, the fluid itself can become thick and corroded over time. If it’s too thick to lubricate the system, you’ll notice it in a steering wheel that doesn’t move properly. You can check if your power steering fluid is thick and dark. That’s a sign it needs flushing and replacement as soon as possible.

Broken serpentine belt

Another common problem is an issue with the serpentine belt. If the serpentine belt is damaged or cracked, you’ll feel stiffness in the way the steering wheel turns. This belt is in constant action as you drive and make adjustments according to road conditions. It can wear down fairly quickly, especially here in Colorado where we face weather extremes throughout the year. If this is the problem, the belt will become looser as you drive. If it breaks, you won’t be able to drive the car at all. Heed to the warning of a problematic steering wheel to avoid bigger repair bills if it fails.

Bad steering rack

The steering rack contains the rack and pinion. Different joints and shafts are responsible for keeping the steering rack attached to the steering wheel. As this rack wears down or is damaged, it will prevent you from steering your vehicle properly. You’ll know when the steering rack is going bad when you notice the wheel is tight only from a cold start. Once it warms up, the lubricant warms up and the steering action improves. It may loosen up as you drive, but the potential for problems is still there.

Power steering pump failure

The power steering pump is what produces the right amount of pressure to allow you to move the steering wheel freely. If this pump no longer works correctly, it becomes more difficult to turn and control the steering wheel. As it wears down, you’ll be required to put more force into the act of turning the wheel. The heavier the vehicle, the harder it will be to complete this action. Bringing it in early means we can check for loose connections or other potential problems before determining if you need a new power steering pump.

Do you have power steering problems? If you see yourself in any of the conditions above, it might be a problem with your power steering system. Bring your vehicle in today and we’ll inspect it and pinpoint the issue.

Stay safe!

Have Advanced Driver Assistance Systems? Pay Attention To The Alignment

December 14, 2021 by Denver Express Car Care

If you’ve hopped behind the wheel of a new car lately, you know a lot of the driving is now done for you. Adaptive cruise control, lane change assistance, collision avoidance, blind spot monitoring – each of these advanced driver assistance systems (ADAS) is designed to make your job a little easier, keeping you and your passengers safer in the process.

To ensure each of these systems works properly, sensors are placed in different regions of your vehicle. With ADAS, every sensor is needed to ensure accurate decisions are made as to how your car moves. If a wheel is out of alignment, or a misdirected sensor, it won’t provide proper input. This can lead to poor performance, or even emergency situations.

Cars have changed so much in the last few years that many dealerships offer driving assistance programs to help you understand these advanced driver assistance systems more intimately before you take the vehicle home. At the very least, you should become familiar with your owner’s manual. It’ll help you become more familiar with the individual systems, and understand the maintenance routine necessary to keep everything working well.

Getting to know your advanced driver assistance systems better

Almost all accidents on the road today are caused by human error. The role of ADAS is to prevent accidents and reduce the impact of those that occur. That’s why you’ll find ADAS applications like:

Automatic emergency braking
Blindspot detection
Lane departure correction and warning
Parking assistance
Traffic sign recognition

Each of these systems is designed applications using interface standards while running vision-based algorithms, relying on individual sensor functions and real-time multimedia. Each autonomous application uses a chip that connects with sensors placed around the vehicle. These sensors take in a large amount of data with the help of image software, sensors, lidar, and radar. It responds to unique situations faster than any human could process.

Have Advanced Driver Assistance Systems? Pay Attention To The Alignment

If you drive a car with ADAS, you know how easy it is to rely on your vehicle performing specific functions. Studies show that in the first month, drivers are fully engaged as they adjust to self-help cars. That slowly wanes as it becomes the new norm for driving. And that’s where you can miss what’s happening to your vehicle over time.

How wheel alignment changes with ADAS

A wheel alignment is a regular routine maintenance item for your vehicle. Like oil changes and checking tire pressure, a wheel alignment ensures your tires safely connect to the road, and keep you pointed in the direction you want to go.

Wheel alignments today are computerized processes where a mechanic aligns all four wheels to ensure your car drives straight. It’s done by adjusting three separate angles of each wheel known as camber, caster, and toe.

These aren’t large adjustments; they are often so small you would have difficulty noticing a change in the tire. That’s because computerized analysis can inspect every aspect of alignment and make micro changes that you and I might overlook. It can bring back your wheel alignment to what the manufacturer suggests.

Improper wheel alignment will wear your vehicle’s tires down faster, and decrease safety while you’re driving. If the wheels aren’t properly connected to the road, you run the risk of having your car steer out of control.

This is why ADAS can help. It also adds more complex nuances to a car’s driving and braking systems.

With a standard wheel alignment, the alignment process involves specialized computer equipment to determine how well the system functions. ADAS takes that to another level. With even more specialized and fine-tuned sensors, the controls for things like steering, brakes, and cruise control all need a higher level of adjustment, referred to as a Safety Systems Alignment.

This alignment starts by adjusting the three angles of the tires. It goes further by calibrating the ADAS cameras, sensors, and radar to ensure complete control of the vehicle. These functions rely on proper alignment of the vehicle to ensure it can be controlled in the manner it was programmed.

For example, one of the most visible systems drivers use is the rear camera system. It tracks the wheel angle to show where your car is traveling in reverse. If this camera isn’t aligned properly or the steering wheel is out of alignment, it can impact what the camera show, which turns the process into a hazardous situation.

To receive a Safety Systems Alignment, it requires:

State of the art equipment – these computers are designed exclusively to monitor cameras and sensors with precision. The slightest error in camera angle could impact the safety of the drive.
Highly skilled technicians – this isn’t a process you can perform on your own. It requires a skilled mechanic who understands how to calibrate every sensor and camera system your vehicle may have.
Extra time – to perform a complete inspection takes time. We have to ensure your tires are properly aligned, as well as ensure your entire safety system meets guidelines.

Do you need an ADAS alignment?

If your vehicle relies on ADAS for any of its safety features, you’ll need a safety systems alignment from time to time.

There are several symptoms that suggest it’s time for a wheel alignment:

You notice your tire is wearing unevenly from tire to tire.
The steering wheel is crooked as you drive straight.
You hear noise as you are steering.
The car pulls to the right or left as you drive.
You hear a squealing noise from the tires.
You install new tires.

ADAS problems don’t show up in the same way. Your wheels may appear to be driving straight, but the sensors aren’t registering it that way. That’s why it’s imperative to bring your vehicle in for regular alignment maintenance to ensure they are operating correctly.

To ensure all of your ADAS features are working properly, schedule a safety systems alignment along with your other routine maintenance. Schedule yours today.
