Does Your Car Really Need a Power Steering Flush?

by

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.

Does Changing a Cabin Air Filter Really Make a Difference?

by

Cars provide an invaluable service. They:

  • Get us from point A to point B each day
  • Shelter us from the heat and cold
  • Allow us to travel long distances comfortably
  • Give us easy ways to transport things we need 
  • Keep us safe from harm

For all those reasons and more, it’s important to keep your vehicle in good working condition. 

When was the last time you thought about checking your vehicle’s filters?

While the oil filter may have been changed the last time you stopped in for an oil change, when was the last time you checked your cabin air filter?

What’s a cabin air filter?

When it comes to filters, your car has several to keep it operating well. They include:

  • Air filter – prevents harmful debris, dirt, and contaminants from entering your engine
  • Oil filter – removes contaminants from your car’s motor oil
  • Cabin air filter – prevents dust, pollen, dirt, and other pollutants from entering your vehicle through the cooling and heating vents

The cabin air filter is the one most vehicle owners miss because they often don’t know it exists. A cabin air filter is specifically designed to help filter the air supply inside your vehicle, creating a cleaner environment while you ride in your car. As you exhale, it takes in the air supply and moves it through the filter. As air comes in from the outside, it filters out pollen and dust to prevent further aggravation for allergy and hayfever sufferers.  

Like other filters, over time, cabin air filters can become dirty and clogged with harmful contaminants and debris. They no longer serve their purpose if they can’t filter air through the filter, and instead let the pollutants and contaminants back into the air supply. 

Does Changing a Cabin Air Filter Really Make a Difference?

If you notice a bad smell coming from the vents as you use heat or air conditioning, there’s a good chance it’s time to replace your cabin air filter. 

When should I replace a cabin air filter? 

While a cabin air filter might not need replacing as frequently as an oil filter, it’s still a good idea to keep it on a schedule and change it often. 

Take a look at your owner’s manual. It will give you an idea of manufacturer’s guidelines, and when your car’s designer suggests you change out the cabin air filter. Typically you’ll find that manufacturers recommend replacing it every 15,000 to 30,000 miles or so. 

Timing may be your starting point, but you should also factor in how you drive. Those who drive in urban, congested areas regularly will need to replace the filters more often. If you live in a rural location and dirt roads are a part of your daily drive, the filter may clog with dust and debris faster than by taking paved roads. 

Will a dirty cabin air filter show signs of wear? 

Like other parts of your vehicle, the cabin air filter doesn’t wear down in an instant. Instead, it will start to provide you with indicators that its clogging and no longer doing it’s job. You may notice:

  • Reduced air flow – when you crank the heat or air conditioning up too high and it still doesn’t seem to get the job done, it may be an indicator of a clogged cabin air filter.
  • A whistling sound – the higher speed you use for controlling the air supply, the higher the whistling sound coming from the cabin air intake ducts. 
  • A distinct musty odor – you can’t ignore the foul smell that comes every time you turn your vents on. It may even worsen over time if you continue to ignore the problem. 
  • Louder noises while the heating or cooling system is running – your heater and air conditioner have to work harder to meet the demands of the system. It’s trying – and you’ll hear it working. The noise will increase until the entire system is well maintained. 
  • Fog on the insides of your windows – if the cabin air filter is allowing pollutants and contaminants to blow out into the air supply, some of the debris may land on your windows and create a fog. This isn’t moisture, it’s actually particles landing on your window, and preventing you from seeing clearly. 

What can you expect from a new, clean cabin air filter?

The good news is that replacing an old cabin air filter with a new one, it will help your car run better. A well maintained vehicle won’t leave you stranded when you least expect it. It will also give you many more years of service, and be a reliable addition to your lifestyle. 

Changing out your cabin air filter will give you:

  • Better performance – air filtration is a crucial part of overall vehicle maintenance. Your car needs two things to operate efficiently – air and fuel. A clean air supply makes every aspect of your vehicle’s operational systems more effective. 
  • Better air supply – how much time do you spend inside your vehicle? According to the EPA, people spend 90 percent of their time indoors, where concentrations of some pollutants have been shown to be as much as five times greater than outdoors. Imagine how many contaminants you’re breathing in if you spend an hour or two each day tucked away inside your vehicle? 
  • Better reliability – how often do you use your heater or air conditioner? Trick question, because you might always have one or the other on, keeping your vehicle at your desired temperature. Every time you operate the heating and cooling system, it depends on the motor for energy. If it isn’t efficient, it requires more power from the engine. That puts undue stress on your engine, meaning it might need repair or even replacement sooner rather than later. 

Is it time to replace your cabin air filter?

If you can’t remember the last time you replaced your cabin air filter, now may be the perfect time. Be prepared for springtime pollen season by giving your ventilation system a little TLC. 

Changing out the cabin air filter will improve air quality and prevent allergy problems by filtering out pollen and mold spores, dirt, and other pollutants. 

It’s one of the easiest ways to ensure your vehicle remains well maintained. 

Does Your Car Really Need a Radiator Flush?

by

Denver is breaking temperature records every single year. It hit 102 in July 2021, 103 in July 2016, and 104 in June 2018. Will we see 105 this year?

When the temperatures creep upwards, it’s important to ensure your car is ready for the heat. Car’s today are built with an internal system to monitor heat and protect the engine. The engine uses antifreeze to keep your engine running, and the entire system cool. 

Is it running properly? Is it time for a radiator flush (also known as a coolant flush)?

It’s essential to keep your vehicle’s coolant fresh by following manufacturer’s guidelines. Ready to learn more? 

What a vehicle’s cooling system does  

If you’ve ever stood near the hood of your vehicle after driving on the highway for a while, you know how much heat is produced underneath the hood. Imagine the parts in action as you fly down the highway at 50, 60, even 70 miles an hour or more. All of that action creates a tremendous amount of heat. 

While the components of a vehicle are created for intense heat, car designers also build in a cooling system to counterbalance the heat, and make sure every part in the system remains in good working condition as you drive. 

If your vehicle didn’t have an effective cooling system, the engine would heat up and stop functioning in a matter of minutes. 

It’s equally important to keep in mind that the cooling system has a job to perform year-round. It works hard to protect the engine as temperatures soar over 100 degrees Fahrenheit, as well as safeguard the engine when temperatures fall below zero. 

Most engines today use a liquid cooling system that works by passing liquid continually through the engine block. Coolant, or antifreeze, is pushed through the engine via the water pump, absorbing heat as it moves through the passages. 

Does Your Car Really Need a Radiator Flush?

As the liquid leaves the engine, it travels to the radiator where it is cooled by an air stream entering through the grill of the car. It cools enough inside the radiator to return once again into the engine, pick up heat, and repeat the process again. 

A thermostat is located between the engine and the radiator to monitor the coolant’s temperature. If the coolant is above a certain temperature, it flows into the radiator to cool. If it’s below, it circulates back into the engine. 

This coolant continues to circulate throughout its life, heating and cooling to protect the internal components of the engine compartment. Coolant, or antifreeze, is composed of ethylene glycol, designed to withstand temperatures tens of degrees below zero, and engine temperatures reaching 250 degrees or above. For most climates, a concentration of 50 percent antifreeze and 50 percent water is sufficient to get the job done. It’s highly poisonous to humans and animals, so keeping it away from both is important. Its slightly sweet fragrance can attract animals and children; take appropriate protection measures. 

Why a radiator flush is needed

Like other fluids in your vehicle, coolant is designed to run nonstop while the engine is operational. Radiator fluid is a protection device, designed to heat and cool as it flows through the system, keeping the components clean and running to do their job well. 

Over time, coolant can start to pick up dirt, debris, and other contaminants that build up in the system. This can lead to corrosion, scaling, rust, or other potential problems that you do not want in your engine or radiator. 

A radiator flush solves this problem. It’s designed to keep the entire cooling system in pristine shape. Think of it as a blood transfusion of the cooling system. 

A radiator flush forces several gallons of cleaner, water, and coolant through the system, eliminating contaminants or build-ups that may have been deposited since the last flush. 

Simply draining the radiator doesn’t do a proper job of removing contaminants. Trace debris may still be stuck inside the system, attached to the various components. By flushing the system, you remove these deposits and create a clean system once again. 

A radiator flush is also designed to repair and protect the various components that may have weakened with age. When you use the right additives and perform a radiator flush as suggested by your car’s manufacturer, it can lubricate the various parts, lengthen the life of the water pump, and help prevent future corrosion before it starts. 

Is it time for a radiator flush?

As a general rule of thumb, most manufacturers recommend having a radiator flush performed every 30,000 miles or 5 years, whichever comes first. Of course, your manufacturer knows best based on how the system was designed. Follow their suggestions to ensure a long life. 

Driving conditions can also impact expectations. Driving up and down the mountain each day can add to the stress of the coolant system. Pulling heavy loads continually can also impact the system. You know your driving conditions best. If you feel your car could benefit from a radiator flush, erring on the side of caution is always best. 

Your vehicle will also give you a sign if it’s time for a radiator flush:

  • You notice a leak by way of a puddle of coolant underneath your car
  • You notice a knocking sound in the engine compartment as you driv
  • Your car starts to overheat
  • You notice visible debris in the coolant
  • Steam or an odd smell coming from underneath the hood

What happens if you don’t flush the radiator

Is a radiator flush really necessary? 

When there is a problem inside the cooling system, you’ll notice any one of the symptoms from above. It can start in the form of a leak, migrate to a knocking sound in the engine, and eventually cause your engine to overheat. The problems won’t go away if you don’t take care of the problem. 

If left unchecked, the symptoms escalate and you wind up with even bigger problems. Further corrosion. Larger leaks. Failing components. Bigger repair bills. 

The easiest way to stop the problem in its tracks is to stick with a schedule and get a radiator flush from time to time, to keep your cooling system operating well. 

When was the last time your car had a radiator flush? 

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

by

“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. 

What Are Auto Diagnostic Tests and Are They Reliable?

by

When some problems arise, you can visually see the issue. If a tire is flat, you patch it. 

Other problems are more difficult to diagnose. You know your car isn’t running correctly. You know there’s a problem deep within the systems. But where?

Luckily, we have auto diagnostic tests to help pinpoint where the problem is. How reliable are auto diagnostic tests?

The history of auto diagnostic tests

Diagnostic tests are a relatively new concept in the automotive industry. Over the past two decades, the industry grew as electronics were introduced and used just as frequently as mechanics. 

The 1990s are considered the start of automotive diagnostics, as electrical structures were introduced into the complexities of car manufacturing. As computer chips became readily available and we moved to higher technological advances, vehicles changed their structures and relied more on sensors.  

These sensors made it easier to locate a problem. Vehicles converted into a digital piece of technology that could be monitored and tested periodically to ensure everything is working correctly. 

Running an auto diagnostic test from time to time helps keep your car safe and operating correctly. For a technician, it’s no longer guesswork when you bring the car in. Trouble codes tell them where a problem originates. Note – the code refers to where the problem lies, not necessarily what the problem is. This is where training and education come into play, where a mechanic uses their knowledge base to get to the root of the problem. 

What Are Auto Diagnostic Tests and Are They Reliable?

What parts can be tested?

Today’s diagnostic tests can reveal issues in all the vehicle’s major systems. 

  • Engine
  • Exhaust system
  • Brakes
  • Transmission
  • Fuel system

Diagnostic tests are designed to ensure your vehicle is running at optimal levels. It diagnoses:

  • Problems with the engine
  • Issues with the transmission
  • Responsiveness
  • Braking issues
  • Potential contamination or faults with the exhaust systems
  • Wear, tear, or breakage with major components

Drivers often have a misconception about what codes on their dashboards are telling them. If the check engine light turns on, they may attempt to pinpoint the problem by looking up the code being referred to. But this is only a starting point. This is where human experience takes over and gets to the root of the problem. 

What auto diagnostic testing is advantageous 

Technically, scheduling an auto diagnostic test isn’t a “needed” service. It’s not something you plan regularly as you would an oil change. 

Diagnostic testing usually comes into play when you start having trouble with your car. Suppose you notice a problem with performance, or a dashboard light suddenly turns on. In that case, a diagnostic test can help pinpoint where it originates, giving mechanics the ability to move right to the problem. 

This eliminates guesswork, and fixing by trial and error. It gets you in and out faster, and gives you better assurance that the original problem is fixed. 

The reliability of an auto diagnostic test

Depending on the age of your vehicle, you may be familiar with guessing at what a problem is. 

Before technology moved into the way a car functions, many of the most common issues were solved through human knowledge. But sometimes, the most challenging problems could take time to diagnose, as the output of the problem might not match what’s truly wrong. 

This meant a driver may have brought the vehicle back in multiple times trying to get to the heart of the problem. 

That’s wasted time, energy, and effort for all parties involved. 

Take smoke coming from the tailpipe as an example. Smoke coming from the tailpipe is a sign of a problem with the engine. But it could be triggered by several different things. 

It might be water vapor that’s built up inside the exhaust system, burning off as you start the car. 

It might be the fuel/air mixture is too rich, and isn’t combusting correctly. 

It might mean oil is burning inside the combustion chamber due to leaky valves or bad piston rings. 

Or it could be a sign coolant is burning in the engine, signaling it may be a blown head gasket, which could lead to the engine overheating.

A mechanic may recognize the signals and fix one issue. But if it’s multiple problems, one may be overlooked, especially if it’s a minor problem. 

A diagnostic test can pinpoint that and lead to fixing the problem before it escalates. 

Accuracy is important

Years ago, cars were more mechanical by nature. Systems were more straightforward, meaning getting to the root cause was easier for a mechanic to perform. 

That hasn’t changed. Some problems are easy to diagnose. A mechanic may see the issue frequently, and know exactly how to fix it. 

But today’s vehicles aren’t just mechanical. They are a blend of mechanics and technology, designed for precise calibration to ensure efficiency and ease at the same time. 

Compare it to a doctor’s visit. You go in with a complaint, a particular weakness or spot that’s troubling you. A doctor will ask questions, gather information, and order tests. These are essentially diagnostic tests. The doctor may have an idea of what’s wrong, but a diagnostic test confirms it, and rules out other causes. 

The same works for your vehicle. 

A mechanic may suspect what’s wrong. A diagnostic test confirms it. And ensures there aren’t other trouble areas that may be causing problems. 

Is it time for an auto diagnostic test?

If you’ve noticed a problem with one of the major systems, a diagnostic test may aid in getting to the root cause. Before you bring it in, gather as much information as possible:

  • What is the problem?
  • When does it occur?
  • What circumstances surround the most noticeable characteristics?
  • Is there a noise? Is it constant or inconsistent?
  • Have you noticed other issues?
  • Have you tried to fix it yourself?

The more information you bring in with you, the easier it will be for our technicians to figure out what’s wrong.

Does Your Clutch Need Repair or Replacing?

by

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?

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?

by

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. 

What Are The Signs of a Bad Timing Belt

by

The timing belt is an integral part of the engine compartment. It’s a rubber belt that synchronizes movement between the camshaft and crankshaft, and ensures the valves stay freely moving and your engine continues to run. 

When operating well, your timing belt helps your vehicle operate smoothly. A bad timing belt can cause problems with the way your car runs, and if left unchecked, can cease operation altogether. 

How do you know if your car’s timing belt is bad? 

Digging deep into timing belts

Depending on how old your car is, you may have also heard a timing belt referred to as a timing chain. A timing chain functions in the same way as a timing belt. The difference is in the location and construction. 

Timing chains are made from metal, where a timing belt is constructed of reinforced rubber. Before rubber became widely used, metal parts were standard in the production of automobiles. Timing belts were introduced in the 1960s as the material became stronger, and it was less expensive to produce. 

Timing chains are built within the engine, receiving lubrication from engine oil that can help it last for a long time. Timing belts are located outside the engine, and will dry out and crack over time. 

While metal is noisier than rubber, improvements have been made over the past few decades to where timing chains are making a comeback in some vehicles. To find out how your car operated, you can check your owner’s manual, or speak with your mechanic the next time you get your car serviced. 

While older timing chains needed replacing every 60,000 miles or so, today’s timing belts can last up to 100,000 before replacement. Many mechanics recommend that if the water pump goes out, it’s best to replace the timing belt at the same time as the belt needs to be removed in order to get to the pump. 

Warning signs of a bad timing belt

As the timing belt ages, it may start offering warning signs that it’s no longer working as well as it should. To prevent the timing belt from going out while driving, ensure regular maintenance to keep oil viscosity normal and ensure all parts are fully lubricated. And watch for these signs. 

A drop in oil pressure

Oil is the lifeblood of your vehicle. Without the right amount of oil, your engine will cease to operate. And that can be a very costly maintenance item. Full replacement is often the only way. 

Keeping an eye on all gauges while driving can alert you to potential problems. A failing timing belt can cause oil pressure to drop. If you notice this, pull over immediately and turn off the vehicle. A failing timing belt can cause the timing of the camshaft to be off, which can cause pieces to break off and fall into the oil pan. This is the worst-case scenario. It’s not something that often happens because most people heed other warning signs first. 

Broken pistons or valves

While it’s not common to have complete failure, if the camshaft and crankshaft aren’t performing correctly, the pistons and valves operate out of sync. This means they may collide with other components in the system, crack off and break. 

Broken parts are never a good thing, especially in a fast moving system. Pieces can be thrown in a variety of directions, causing even more destruction. If you see sudden changes in how your vehicle operates, and hear noises that come on suddenly, pull over and turn off your engine immediately. 

Rough idling 

When you look at a timing belt, you’ll notice they have little teeth or ridges on the edges to help it move. This is to help it move between the gears, allowing it to rotate through the various components of the system. As the belt ages, these ridges smooth down, the belt becomes looser, and the gears don’t mesh in quite the same way. This process can cause the engine to idle rough. The longer this continues, it can eventually lead to the engine stalling. 

Misfiring

As the timing belt begins to slip, it can cause a variety of problems. Slipping away from the gears causes the pistons and valves to open and close out of sync. This results in a misfire. While it can be easy to ignore, this is an indicator that the system isn’t performing up to par. If allowed to continue, you risk permanently damaging your engine. 

Smoke 

The timing belt is in constant rotation, keeping everything moving in perfect condition. This also ensures proper air intake, including exhaust. If there is a problem anywhere in the rotation process, the system may take in too much air, or release too much exhaust. In this case, you’ll often see an unusual amount of smoke escaping as the car operates. 

Prevention is key to avoiding timing belt problems

Having a timing belt go out isn’t something car owners have to experience. A little prevention goes a long way in keeping everything running well. 

If your vehicle operates using a timing chain, oil viscosity is key. Use your vehicle’s suggested motor oil to ensure it’s properly lubricated. When in doubt, error on replacing your oil frequently to ensure good quality motor oil is always running through the system. Today’s lighter oils can penetrate more areas to ensure every component stays running well. 

You can also have your vehicle checked from time to time to ensure the various systems and components are working well. Pay attention to manufacturer’s suggestions, replacing certain parts before they have a chance to go out. 

Have you experienced a bad timing belt before? 

What Happens If You Drive With a Bad Brake Caliper?

by

When you hop into your car and drive to school or work, you don’t think much about how it operates. You turn the key and go. 

Yet if you stop to think about each system, chances are you’d push the braking system to the top of the list in importance. After all, without the braking system, your car would experience extensive damage pretty quickly, while you may face injury yourself. 

How much do you know about the braking system? Brake pads. Rotors. Brake fluid. Calipers. There are several major components that create an effective braking system. If any one piece is damaged or not working correctly, 

Understanding brake calipers

While most people understand that pushing on the brake pedals initiates the braking process, they don’t understand a brake caliper’s job. Brake calipers are a crucial part of making your car slow down and come to a stop as you push down on the brake pedal. 

A caliper is a component of the disc brake system, which is what most cars have in the front brakes. 

What Happens If You Drive With a Bad Brake Caliper?

The brake caliper sits like a clamp on a wheel’s rotor. You can actually see it on most cars if you glance through the spokes on your wheel. The caliper houses the brake pads and pistons. Its main purpose is to clamp down on the rotor, creating friction with the brake rotors. 

When you press down on the brake pedal, brake fluid creates pressure, causing the piston to move against the brake pad, which in turn pushes it against the brake rotor. The more pressure you put on the brake pedal, the more friction between the pads and rotors. Until your vehicle comes to a complete stop. 

The brake caliper sits inside the wheel, and is connected to the master cylinder through a series of tubes, hoses and valves. These connections push brake fluid through the system to make it work. If any piece or component in this system isn’t operating well, it can greatly impact the braking process. And that can put you and the people around you in danger. 

What happens if you drive on a bad brake caliper?

If you drive with a bad brake caliper, you’re risking the entire braking system not operating as it should. 

The caliper houses the brake pads and pistons. A stuck caliper means the brake pad will not completely pull away from the brake rotor. A part of the brake pad will have constant pressure against the rotor while you drive. Which also means part of the braking system will be engaged all the time. 

This can add stress to the entire braking system. It can also add stress to the transmission, which can cause failure earlier. 

At a minimum, it will cause your brake pad to wear down prematurely. This means you’ll be replacing your brake pads more frequently, and putting yourself at risk if it doesn’t engage properly when you step on the brake pedal. 

As soon as you notice a problem, fixing it is your best solution. 

When is it time to replace brake calipers?

While you might not notice a problem right away, eventually you’ll start to notice your brakes aren’t working the way they should. A bad caliper can cause a variety of warning signs, signaling to you a potential problem. 

Pulling to the right or left – one of the biggest warning signs is a vehicle that doesn’t drive straight. As you’re driving down the road, does your vehicle pull to the right or left? As you’re braking, do you notice the pull get more prominent? If one of the calipers is bad, it’ll impact the connection between the brake pad and the rotor, causing your vehicle’s stopping function to be compromised. 

Heat coming off the wheel – as you can imagine, when the brake pad connects with the rotor, it creates a lot of friction. This friction gives off tremendous heat. Under normal driving conditions, this heat dissipates quickly. But if the connection is constant, the heat continues to grow. If you suspect a stuck caliper, stop the vehicle and turn off the engine. Place your hand near the wheel without touching it. Can you feel more heat than the other wheels? This may be a sign of a stuck caliper. Bring it in for an inspection right away. 

Dirty brake pads – imagine all the wear and tear your brake pads see as you drive. From ice and snow, to the one-hundred degree days in the summer months, your brake pads deal with a lot of dirt and debris kicked up from the road as you drive. Sometimes that dirt can build up on your brake pads, causing the caliper to stick. A mechanic may be able to clean them and get them working once again. If they are worn, you can replace the brake pads before they cause any more problems. 

Brake hose problems – the braking system contains multiple parts to remain in good working condition. If the brake hose wears out, it won’t deliver brake fluid properly to the various parts. Without brake fluid, the master cylinder won’t be able to control the brake caliper movement. This can be assessed by a mechanic, and a brake hose replacement may be necessary. 

The best way to keep your calipers in good working condition is to ensure your brake pads are replaced and the brake fluid is topped off. Brake pads are the most frequently part replaced on the braking system, with most brake pads being replaced every 10,000 to 20,000 miles. 

Tracking your maintenance items can alert you to potential problems before they exist. Are your brake pads nearing your vehicle’s suggested guidelines? Are you pushing the 20,000 mile marker? It may be time to schedule an inspection with one of our mechanics. We can evaluate the entire system, and ensure your brakes are safe and ready to work every time you drive.
