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.

Hybrid Car Maintenance – Every Car Needs a Little TLC From Time to Time

December 7, 2021 by Denver Express Car Care

If you’re thinking of buying a car today, there’s more to it than deciding on a brand, make, or model. The automotive industry is changing fast enough now, you have to consider whether you want to stick with gas operated, or move to hybrid or electric technology.

Selecting the make and model is only the first step in deciding what will work best for your lifestyle. Before you choose based on looks and gas mileage, consider your maintenance routine too. What does hybrid car maintenance look like? Is it much different than what you’re used to with your gas-powered vehicle?

Hybrid car use in America

Hybrid and battery-operated cars are growing in interest. In 2020, there were 6.8 million battery electric vehicles in use globally, with more than half of them being added to the road during the course of the year.

Tesla might have given the industry its biggest push, but it by far isn’t the only choice. Pick your favorite car manufacturer – chances are they have an electric model.

A hybrid rests somewhere between a gas-powered and electric car. A hybrid combines at least one electric engine with one gas-powered engine to move the car. Sometimes the electric motor will do all the work. Sometimes it moves to the gas-powered engine. Sometimes the two work together to keep the car moving. This action results in a more efficient car with less gas burned and better fuel economy. In some cases, adding electric power can even increase performance.

So what’s the right choice for you as we move forward with technology? If you’re concerned about the future of gas-powered vehicles, and aren’t ready for a fully electric model, a hybrid vehicle may be the best choice for you.

What about hybrid car maintenance? How will your regular routines change?

Hybrid car maintenance

Because hybrid vehicles have both a gas-powered and electric engine, they need the basic maintenance offered to a gas-powered car, with a few additional needs for the electric. Hybrids will still need things like regular oil changes, belt replacement, and tire alignment. Because it runs on a battery, you’ll still have to replace the battery. For the electric battery, most today come with warranties for extended periods of time and a long life – 8 year, 80,000 miles, for example. That ensures the electric battery continues to operate without replacement for a long time.

To start thinking about what a hybrid car will need for a regular maintenance routine, consider adding these tasks to your schedule.

Check car fluids

Because hybrids run on both gas and electricity, they will need a regular course of action when keeping the engine compartment clean and running well. Just like standard combustion engines, you’ll have to replace your motor oil regularly. Beyond that, you’ll have to replace coolant, transmission fluid, and brake fluid based on the needs of your car. Check with the owner’s manual that came with your vehicle for more information. Or work with a mechanic experienced in working with EV technology to ensure every aspect of your vehicle continues to operate well.

Cooling system check

Hybrids have a more complex cooling system because it relies on two different types of power to keep the vehicle running. To keep everything under the hood cool, it requires a complex system relying on a split radiator to keep the internal combustion engine cool. At the same time, another series of circuits serves the various electrical components. Each hybrid system can be slightly different, so it’s important to follow the guidelines based on the manufacturer and make of your vehicle for further advice.

Hybrid battery

Because hybrid vehicles rely on both gas and battery for power, the batteries won’t travel as far as a fully electric vehicle. Depending on the make and model, you can have a limited range of 70 to 250 miles for each charge. The battery itself will last anywhere from 70,000 to 100,000 miles.

You might be used to allowing your mobile technology to fully drain before plugging it in. Hybrid batteries work similarly. It’s best to drain the battery down and then recharge it to full capacity. This keeps it functioning at its best. Freezing weather can impact how well a hybrid battery operates. Consider keeping it in a garage, or buying a heater.

Tire inspection

Whether you drive a gas-powered, hybrid, or electric vehicle, the reliance on tires to get you from point A to point B will always be the same. Your tires connect to the road and provide safe passage as you drive. If your tires aren’t in top shape, problems can start to build throughout the vehicle.

Do a spot check periodically to ensure your cars are in good condition. You can do the penny check to ensure the tread depth is in proper proportion. Most cars today come with an electronic tire pressure sensor. Ensure each tire is properly filled for maximum wear. Keep your tires in proper alignment, and have them balanced and rotated regularly. Every other oil change is a routine that will help you stay on track.

Brake check

Hybrid vehicles use regenerative braking technology to recharge the battery. When the driver removes their foot from the accelerator to coast or applies the brakes, the electric motor spins in reverse and acts as a generator to recharge the battery. This energy also adds resistance to the wheels without the use of the conventional brakes, which means the brake pads and other parts of the braking system won’t wear down as fast as it does with a traditional gas-powered system.

Still, your braking system is one of the most important parts of your vehicle. Routine checks will ensure everything is working correctly. If you’re heading out of town, or head into the mountains regularly, it’s a good idea to put a maintenance visit on your calendar periodically to ensure the safety of your braking system.

Do you have a hybrid vehicle?

Technology is allowing advances in our transportation system like never before. Hybrid car maintenance may be slightly different from traditional, but it’s still necessary to ensure your vehicle stays safe throughout the years.

How Old Is Your Car Battery? It Might Be Time For a New One

December 4, 2021 by Denver Express Car Care

On average, you can expect your car battery to last anywhere from two to five years. Of course, that depends on the battery you install, driving conditions, and the environment in which you drive.

Here in Colorado, a lot can impact your car battery even if all you do is drive to work and run a few errands each day. Your vehicle is subjected to:

Intense summer heat
Bitter cold winters
Ice, snow, and slush
High altitude driving
Short distance driving

And those are just for a start. Every time you take your car out, it impacts your car battery. Even leaving it at home and not starting your car can take its toll over time.

How a car battery works

Our lives are filled with devices that run off of batteries. Take a fully charged battery, pop it into your device, and you’ll have hours, days, or even weeks of use.

Some batteries you must replace every so often; when they die, it’s time for a new one. Other batteries you can charge over and over again.

A car battery is the latter. When you turn the key or press the button to start your car, that process sends a signal to the battery that starts a chemical reaction inside the battery box. This reaction creates electrical energy that activates the motor running and the engine cranking.

How Old Is Your Car Battery? It Might Be Time For a New One

Car batteries are designed for starting, lighting, and ignition. It sends short bursts of energy to your lights, accessories, and engine. The energy is transferred to the alternator once the battery powers up the engine. As it runs, it will fill up the car battery and ready it for the next use.

How long a car battery will last

Think about how often this process occurs throughout your day. You start the vehicle to take the kids to school, drive to work, head out for lunch. You stop and start your car over and over again.

While the average car battery will last between 2 to 7 years, there are several ways you can increase the likelihood your battery will have a long life:

Short rides – when you start your car, the battery drains power as it provides energy to kick everything into action. As you drive, that energy is replaced, so the battery will be ready to operate when you start the car up again. If you limit your driving to short rides, it never has a chance to build power back up. Plan longer drives periodically to ensure your battery receives the full charge.

Turn off lights – do you flip on interior lights frequently? Do your headlamps stay on even after you turn off the engine? Lights can be a big drain on the battery, especially if they stay on for hours or days at a time. Build a habit of checking to ensure lights are off before walking away from your car.

Battery check – what does your daily drive look like? Do you take rough roads? Do you navigate potholes and speed bumps that can jar anything loose? It’s a good idea to check underneath the hood from time to time to ensure everything is in its place. The battery might come unfastened, which can cause damage or short circuit. Watch for corrosion around the battery terminals; you can clean it with a simple mixture of baking soda and water.

Turn off electronics when the engine isn’t running – you wait for the kids after practice. You’re early for a meeting. There are a lot of reasons we sit inside our vehicles and wait – why not use things like the radio, lights, or air conditioning while we do so? Because it adds wear and tear to your battery. If you find yourself doing this regularly, look for ways to change your patterns. It’ll help extend the life of your car battery.

Signs your car battery may be dying

No matter how well you take care of your car battery, it will need replacing every few years to keep your vehicle running well. Luckily, a weak car battery alerts you with a few telltale signs before it dies.

Trouble starting – as the components of the battery begin to wear, they won’t operate at the same level as when the battery was new. You’ll notice it as your car has trouble turning over.

Electrical problems – because it’s the battery’s job to power the vehicle’s electronics, you’ll notice a change in the way they function. If your headlamps seem dim, it could be a sign of a weak battery.

Check engine light – the check engine light is one of the most frequent dashboard icons to light up. If you pay attention to how your car operates, you can usually deduct what might be wrong and make the necessary adjustments. When in doubt, bring it in, and we can help pinpoint the problem.

Bad smell – when a battery is damaged or not functioning correctly, it can cause the battery to leak. If you smell rotten eggs, a leaking battery may be the culprit. Replace it as soon as you can.

Corrosion around the connectors – pop the hood and glance over the various components from time to time. A white substance on the metal parts of the battery is a sign of corrosion. Corrosion can lead to voltage issues, which means you’ll have trouble starting your car.

Damaged battery case – Colorado’s weather can do funny things to a battery case. Intense heat, bitter cold, and everything in between can sometimes cause a battery case to swell and crack. This can lead to a variety of harmful effects. If you notice anything unusual, bring it in for us to inspect.

Age – when did you last replace your battery? Pay attention to dates, and you can start recognizing weaknesses in the way your battery is operating. If it’s been three or four years, it might be worth replacing your battery before it leaves you stranded.

Is it time to replace the battery in your vehicle?

Why Your Car Needs Regular Tune Ups

November 24, 2021 by Denver Express Car Care

A car is comprised of over 10,000 components working together to provide you with reliable transportation. If it’s well cared for, it will continue running indefinitely. That’s why car manufacturers recommend regular tune ups to keep their vehicles operating at their best.

But what does that mean? The concept of a regular tune up is a bit vague. It can mean one thing to one driver, and have a completely different meaning to someone else.

What is a tune up?

When you bring in your car for a tune up, it will move through two processes: an inspection and servicing.

The inspection process starts with a visual check of all the major components of the vehicle. A mechanic will determine how well the engine is performing by inspecting the spark plugs, air filters, oil and coolant levels. They will assess the fuel system by making sure the fuel filter is clean and unclogged.

If a mechanic sees any potential problem, the inspection process can grow from there to assess other systems and ensure they are operating well.

The tune up service depends on the results of the inspection. Every tune up process will be different, with recommendations made based on what is found. The goal is to ensure the engine operates properly, receives the right amount of fuel and oil, and functions well based on the current road conditions. Suggestions for servicing might be as simple as adding coolant, to more complex issues that require replacing various parts of the system.

Typically, a mechanic runs through a series of tests to find potential problems before they escalate. The most common parts replaced after an inspection include:

Fluids – cars operate well if the fluids are topped off and in good condition. Mechanics often recommend replacing or topping off motor oil, coolant, transmission fluid, or power steering fluid after a thorough check.
Filters – a filter’s job is to keep contaminating particles from entering a system. Once a filter is dirty or compromised, it can no longer do its job effectively. If a mechanic notices a dirty filter, changing out may be an easy solution to the problem.
Belts and hoses – belts and hoses keep your car operational. It’s how power moves through the various components to keep your car running well. Cracks, leaks, and other damage can compromise the working condition of the various systems underneath the hood.
Ignition – this includes the electrical components of your vehicle, including spark plugs, wires, and coils.

Warning signs your car needs a tune up

Cars rarely fail without indicators far in advance. It’s your job to notice transitions in the way your vehicle is operating, and bring your car in for servicing before things move from bad to worse.

Luckily, there are built in warning signs that alert you to potential problems.

Dashboard lights – today’s vehicles are technologically advanced, and can easily alert you to potential problems before they grow. Every dashboard light tells you your vehicle is operating outside of “normal.” It gives you a chance to bring it in for servicing before it gets worse. An engine light can mean many things. A tune up will get to the root cause, and fix the problem quickly.

Brakes – the brake system is one of the most vital. If you notice squeaks when you apply the brakes, or the pedal feels a bit spongy as you apply pressure, it’s time to bring your vehicle in for inspection.

Fuel economy – with every fill up, pay attention to the gas mileage you got for that tank of gas. If you notice changes in gas mileage without a solid reason, it could be that your vehicle isn’t processing the gas as efficiently as when it was new. That can impact the way the engine performs, as well as effect the emissions being released every time you drive.

Stalling – as you apply pressure to the accelerator, does the car lag, jump, work to catch up with your demands? This can put you in a dangerous situation on a busy road, and continue causing damage underneath the hood.

Vibrations – whenever your vehicle shifts in ways it normally doesn’t, shakes as you drive, or hesitates, it’s a sign there’s a problem within the system. To stay safe, a tune up can find out what’s wrong.

While it’s important to bring your vehicle in for a tune up if you notice something not working right, it’s equally important to do so regularly. Manufacturers make recommendations based on the way your vehicle was constructed to ensure it continues working well throughout the life of the vehicle.

Modern vehicles only need tune ups every 30,000 to 100,000 miles. If you’re not sure about your vehicle, check the owner’s manual for more details. It’s best to stick with a plan to ensure a long life for your car.

What a car tune up includes

When you bring your car in for servicing, it typically will include:

Filter replacement
Change out spark plugs
Replace all worn components
Preventative maintenance
Fluid replacement
Examining the electrical connections
Repairing and replacing belts, hoses, and wires

If you stick with a regular maintenance plan, your tune up should be uneventful, with updates to the needed components.

Maintenance is the key to keeping your car well conditioned for as long as you own your vehicle.
