All About Timing Belts: What They Do and When to Replace Them

by

Cars have more than 10,000 parts ensuring they stay operational for many years. 

Some components you understand you’ll have to replace from time to time. You replace motor oil, windshield wipers, and tires on a routine. 

But what about a timing belt? (Sometimes referred to as a timing chain.) How much do you know about timing belts? Or what the maintenance schedule looks like?

The more you know, the better prepared you’ll be to recognize the warning signs of a timing belt failing, and what you should do along the way. 

What is a timing belt?

Every internal combustion engine has a timing belt. It synchronizes the rotation of the crankshaft and the camshaft(s), ensuring that the engine’s valves open and close properly during the engine’s operation. 

The timing belt is typically made of rubber with high-tensile fibers, and it is driven by the crankshaft and wraps around the camshaft(s), keeping them synchronized with the crankshaft.

Timing belts are crucial components of an engine, as they ensure that the valves open and close at the correct time. This prevents collisions between the valves and the pistons. 

All About Timing Belts: What They Do and When to Replace Them

If the timing belt breaks or slips, the engine may stop working or suffer serious damage, so following the manufacturer’s recommended maintenance schedule to replace the timing belt is essential.

What function does the timing belt play in a car’s operation?

The timing belt plays a crucial role in a car’s operation by synchronizing the rotation of the engine’s camshaft(s) and crankshaft. The camshaft(s) control the opening and closing of the engine’s valves, while the crankshaft controls the movement of the pistons.

The timing belt ensures that the camshaft(s) and crankshaft are in the correct position, so that the valves open and close at the right time with the movement of the pistons. This is important because if the valves are not properly timed, they can collide with the pistons, causing severe damage to the engine.

Regular maintenance, including replacement of the timing belt according to the manufacturer’s recommendations, is essential to prevent potential damage to the engine and ensure reliable performance.

Signs a timing belt is failing

Luckily, a timing belt rarely fails without warning signs of a potential problem. Listen to your car – is it making noises? Take a whiff – do you smell something that’s not quite right? Your vehicle provides lots of guidance – if you pay attention. 

Manufacturers recommend replacing the timing belt every 30,000 to 120,000 miles, depending on the make and model. Manufacturers base this engine performance and driving conditions, which change in every situation. Start by checking your owner’s manual. Then pay attention to your car, especially if you start to notice:

  • Engine misfires – A worn or damaged timing belt can cause the engine to misfire or run erratically, leading to poor performance and reduced power.
  • Ticking noise from the engine – A ticking noise from the engine can indicate that the timing belt is loose or damaged and is not properly controlling the opening and closing of the valves.
  • Difficulty starting the engine – A worn timing belt can cause the engine to struggle to start or not start. This is because the belt may have stretched, causing the engine to be out of sync.
  • Oil leaking from the engine – A damaged timing belt can cause oil to leak from the engine, which can be a sign that the timing belt needs to be replaced.
  • Visible wear or damage – It is time to replace it if you can see signs of wear or damage to the timing belt, such as cracks, missing teeth, or fraying.

When should you replace a timing belt?

The timing belt is a critical component in a car’s engine, and it is essential to replace it before it fails. The manufacturer’s recommended replacement interval for the timing belt varies depending on the make and model of the vehicle. It can range from 30,000 to 120,000 miles or 5 to 10 years, whichever comes first. It is essential to refer to your car’s owner’s manual to determine your vehicle’s recommended replacement interval.

It is generally recommended to replace the timing belt as a preventative maintenance measure before it reaches its recommended replacement interval. This is because a failed timing belt can cause severe damage to the engine, resulting in expensive repairs.

If you notice any signs of a failing timing belt from above, you should have it inspected by a qualified mechanic as soon as possible. Additionally, if you purchase a used car and do not know the service history of the timing belt, it is recommended to have it replaced as a precautionary measure.

Should you replace your timing belt yourself?

In most cases, the answer is: No. The timing belt is complicated to replace and is often in a place that makes it difficult to service. 

Special tools are often needed to install a timing belt correctly. Plus, other parts may need replacement while installing a new timing belt. Aligning the camshaft gears with the crankshaft gear should follow the manufacturer’s specs. Even if a gear is one “tooth” off, it has the risk of running rough. 

And that could be detrimental to the overall operation of your vehicle. 

When the pros replace the timing belt, they often replace things like the drive belts, water pump, change the motor oil and filter, and flush the cooling system. It all depends on the timing belt’s location and what makes the most sense for your vehicle. 

What condition is your timing belt in?

Those 10,000 parts go through a lot each day. 

  • They take on the hottest days and the snowiest conditions.
  • They hit potholes, speed bumps, and road construction. 
  • They drive to work, sit in the carpool line, help you run errands, and sit through miles of traffic.

Each moment impacts your car differently. How is each part still working together?

The only way you’ll know is through regular servicing. 

It’s the one way one of our trained mechanics can determine if each part on your vehicle is still working together.

Troubleshooting Common Electrical Issues in Your Car

by

What energy source does your vehicle use? It uses gasoline to propel you down the street, but it also uses electricity to operate many of the systems you use every day. 

Common electrical issues vary greatly, with most of them stemming from a problem with the battery. But it’s not always the case. In newer cars, the electrical system is more complex, meaning there’s always a chance for something to go wrong. 

What causes the most common car electrical issues?

Troubleshooting electrical problems can always be a little tricky. That’s why leaving it to an expert is almost always best. Still, the more you understand about vehicles, the more likely you are to pinpoint the problem and discover why your car has electrical problems. The solution to any electrical problem starts by locating where the issue originates. It might be:

Dead battery – A dead or dying battery is one of the most common reasons a car won’t start. If the battery is not holding a charge, it could be due to a faulty alternator, a bad connection, or other issues.

Faulty alternator – The alternator is responsible for charging the battery while the car is running. If it’s not working properly, the battery will not charge, and the car will eventually stall.

Troubleshooting Common Electrical Issues in Your Car

Blown fuses – Fuses protect electrical components in the car from surges of electricity. If a fuse blows, it can cause problems with various systems in the car, such as the headlights, radio, or power windows.

Faulty starter – The starter is responsible for turning the engine over when the ignition key is turned. If the starter is defective, the engine may not turn over, and the car won’t start.

Bad wiring – Corroded, damaged, or loose wiring can cause a variety of electrical problems in a car, including issues with the lights, radio, and other electrical components.

Computer problems – Today’s modern cars have sophisticated computer systems that control various functions. If the computer system malfunctions, it can cause a range of electrical problems.

How to diagnose more common vehicle electrical problems

It’s easy to tell if your car’s battery is dead. If your car won’t start, it’s most likely a worn out battery. You can further identify a dead battery by flipping on the headlights. If they are dim or won’t turn on, it’s most likely a dead battery. 

But what if your car’s accessories still work? Diagnosing common vehicle electrical problems can take a little more sleuthing. 

Check the battery – A dead or weak battery can cause a range of electrical problems, including difficulty starting the engine, dim headlights, and a dead radio. Use a voltmeter to check the battery voltage, and if it’s low, try jumpstarting the car. If the battery doesn’t hold a charge, it may need to be replaced.

Check the fuses – Blown fuses can cause various electrical problems in a car. Use the owner’s manual to locate the fuse box and check for blown fuses. If you find a blown fuse, replace it with a new one with the same amperage rating.

Check the alternator – The alternator is responsible for charging the battery while the car is running. If the alternator is not working properly, the battery will eventually die, and the car will stall. Use a voltmeter to check the alternator output voltage; if it’s low, it may need replacing.

Check the starter – If the engine doesn’t turn over when you turn the key, the starter may be faulty. Check for a clicking sound when you turn the key; if you hear it, the starter may need replacing.

Check the wiring – Corroded, damaged, or loose wiring can cause a range of electrical problems in a car. Use a multimeter to check the continuity of the wiring and look for any signs of damage or corrosion. Repair or replace any damaged wiring.

Check the computer – Many modern cars have sophisticated computer systems that control various functions. If the computer system malfunctions, it can cause a range of electrical problems. Use a diagnostic tool to check for error codes and diagnose the situation accordingly.

Keep in mind that these are just general tips, and diagnosing electrical problems in a car can be complex. If you’re uncomfortable working on your car’s electrical system, it’s best to take it to a qualified mechanic for diagnosis and repair.

Is it an electrical problem? Here’s how you know.

If your car won’t start when you turn the key, it’s most likely your battery. That’s an easy troubleshooting test. However, electrical problems aren’t always that easy to detect. 

You might experience battery problems without it being a dead battery. It could be your alternator or problems somewhere deeper in the system. Take a look at the battery cables checking for corrosion. Check accessories like headlights and the radio; if they work, it’s not your battery. Jumpstart your vehicle and see if it holds a charge. This can be a good indicator if it’s your battery. 

Your car’s fuse box prevents overvoltage or short-circuiting. It protects other vital components of your electrical system from getting too much energy. In some cases, a fuse can blow for no real reason. If this is the case, replacing it may fix the problem. But if fuses burn out repeatedly, it’s a bigger problem with the electrical system. Fuses protect the electrical system from further damaging your vehicle’s other, more complex parts. Diagnosis and repair are the best road to preventing more significant problems.  

Burning smells are also a clear indicator of an electrical problem. If you experience a burning smell, you should stop driving your car immediately. It’s a sure sign of an electrical malfunction, and could quickly lead to bigger problems.

The Importance of Tire Rotation for Your Vehicle

by

Automobiles are expensive. Prices are steadily rising. According to a recent JD Power survey, the average price paid for a new car was $46,437 in January 2023. 

That makes maintenance that much more critical. Do you know the importance of tire rotation? 

What is tire rotation?

Tire rotation moves the tires from one position to another. Typically, this involves moving the front tires to the rear and the rear tires to the front, but sometimes the left and right tires may also be swapped. Tire rotation aims to promote even wear on all four tires, which can help extend their lifespan and improve overall handling and performance.

Tire wear can be uneven due to a variety of factors, such as the weight distribution of the vehicle, the alignment of the wheels, and driving habits. By rotating the tires regularly, drivers can ensure that the tires wear evenly and avoid the need to replace them prematurely. 

Most tire manufacturers recommend that tire rotation be done every 5,000 to 8,000 miles. Check your owner’s manual for more information.

The Importance of Tire Rotation for Your Vehicle

Why is tire rotation important?

Swapping tires from one position to another may be easy to forget. Yet it can have a significant impact on the longevity of your tires. Schedule tire rotation regularly for several reasons:

Even wear – Tires can wear differently based on their position on the vehicle. For example, front tires typically wear faster than rear tires due to the engine’s weight and the fact that the front tires are responsible for steering and braking. By rotating the tires, the wear can be distributed evenly, which helps extend the tires’ life.

Prolongs tread life – Tires average about six years of life. Rotating the tires regularly ensures every aspect of the tire tread will be utilized throughout its life. How a tire wears depends on many things, including tire quality, design, driving style, and geographical location. A car subjected to intense heat and sunlight can also cause premature wear.  

Improved handling and performance – Uneven tire wear can lead to handling and performance issues, such as vibrations, pulling to one side, and reduced traction. By rotating the tires, drivers can maintain consistent handling and performance, improving safety and comfort.

Cost savings – Tires can be a significant expense for vehicle owners. Rotating the tires regularly can help to extend their lifespan. This means the tires won’t wear out prematurely, saving you money by not having to replace tires as frequently.

Warranty requirements – Some tire manufacturers require regular tire rotation as part of their warranty requirements. Failure to comply with these requirements can void the warranty.

What is a tire rotation pattern?

It may seem like a simple task – simply swap one tire for another. Yet there are specific guidelines for how you rotate your tires. 

A tire rotation pattern refers to the specific way in which the tires are rotated on a vehicle. Several tire rotation patterns are designed to address different types of tire wear and specific vehicle configurations.

Some of the most common tire rotation patterns include:

Rearward cross – This pattern involves moving the rear tires to the front and the front tires to the opposite sides of the rear axle. For example, the left front tire is transferred to the right rear position, and the right front tire is moved to the left back position. This pattern is commonly used on front-wheel-drive vehicles.

Forward cross – This pattern is similar to the rearward cross pattern, but the front tires are moved straight back to the rear, and the rear tires are moved to the opposite sides of the front axle. This pattern is commonly used on rear-wheel-drive vehicles.

X-pattern – In this pattern, the tires are moved diagonally, with the front left tire moved to the rear right position, and the front right tire moved to the back left position. The rear tires are moved straight forward to the front.

Side-to-side – This pattern involves swapping the left and right tires while keeping them in their original position on the vehicle. This pattern is commonly used on cars with directional tires, which can only be rotated side-to-side.

What happens if you don’t rotate your tires regularly? 

Tire rotation seems like such a simple thing. In fact, it might be easy to forget. Yet forgetting can cause several different issues, including:

Uneven tire wear – Tires can wear unevenly if not rotated regularly. When this happens, tires on one side of the vehicle may wear more than the other side. This can lead to handling and performance issues, such as vibrations, pulling to one side, and reduced traction.

Reduced tire lifespan – Uneven tire wear can also cause tires to wear out more quickly, meaning you’ll have to buy new tires more frequently. This can be expensive, as tires are a significant expense for vehicle owners.

Safety issues – Uneven tire wear can affect the handling and performance of the vehicle, which can compromise safety. Worn tires may not provide adequate traction in wet or slippery conditions, increasing the risk of accidents.

Warranty issues: Some tire manufacturers require regular tire rotation as part of their warranty requirements. Failure to comply with these requirements can void the warranty.

Have you scheduled tire rotation for your vehicle?

Like every maintenance item on your vehicle, tire rotation is easy to forget but will cost you even more in the long run. 

Like oil changes, put tire rotation on your calendar and bring it in for regular maintenance. If you haven’t had your tires rotated in a while, make today the day you bring your vehicle in.

Tips for Maintaining Your Car’s Air Conditioning System

by

The seasons are changing. Summer is a short time away. 

Before you know it, the temperatures will be climbing up, up, up. 

Will your car’s air conditioning system be ready for the challenge? Performing a little TLC now will help maintain your car’s air conditioning system no matter what the weather is like outside. 

Your car’s cabin can reach as much as 140 degrees on the hottest days of the year. If you want your AC system to work no matter what the thermometer reads, you’ll have to add a maintenance visit to your regular routine. 

Understanding a car’s air conditioning system

The air conditioning system in a car is responsible for cooling and dehumidifying the air inside the cabin. The basic components of a car’s AC system include:

  • The compressor is the heart of the AC system. It is driven by a belt from the engine, which compresses the refrigerant gas and circulates it through the system.
  • The condenser is located at the front of the car and releases heat from the compressed refrigerant gas. It looks like a small radiator and has fins to dissipate heat.
  • The evaporator is inside the car’s cabin, typically behind the dashboard. It absorbs the heat from the air inside the vehicle, causing the refrigerant to evaporate and turn into a gas.
  • The expansion valve or orifice tube is a small component between the evaporator and the compressor. It controls the flow of refrigerant into the evaporator.

The air conditioning system compresses the refrigerant gas in the compressor and then circulates it through the system. As the compressed gas moves through the condenser, it releases heat and becomes a high-pressure liquid. The liquid then flows through the expansion valve or orifice tube, which lowers its pressure and causes it to evaporate as it passes through the evaporator. The evaporating fluid absorbs the heat from the air inside the cabin, which is then blown out through the car’s vents.

Tips for Maintaining Your Car's Air Conditioning System

The system is closed and continuously circulates the refrigerant gas, which means that a low refrigerant level or a malfunctioning component can reduce cooling efficiency or cause a system failure. Regular maintenance and servicing can ensure the proper functioning of the AC system.

How do you know if your car’s air conditioner is failing? 

Several signs can indicate a failing AC system in a car. The most common include:

Reduced cooling performance – If your car’s AC system is no longer cooling the cabin as effectively as it used to, this can be a sign of a problem. The air from the vents may feel warm or not as cool as it should be.

Strange noises – Unusual sounds from the AC system, such as grinding, hissing, or rattling, can indicate a problem. A malfunctioning compressor or other components can cause these noises.

Foul odors – If you notice a bad or musty smell from the AC system, this can be a sign of mold or bacteria growth in the evaporator. This can also cause health problems if left untreated.

Water leaks – If you see water leaking from the AC system, this can indicate a clogged drain tube or a malfunctioning evaporator.

AC system not turning on – If the AC system fails to turn on, this can be caused by a blown fuse, a faulty compressor, or an electrical problem.

If you notice any of these signs, it is vital to have the AC system checked by a qualified mechanic. Ignoring these issues can lead to further damage to the AC system and higher repair costs. 

What regular maintenance items should you do to keep the air conditioner operating well?

Nothing is worse than being surprised with an air conditioner that suddenly doesn’t seem to work on the hottest day of the year. To avoid this, stick with a regular maintenance schedule to ensure its proper functioning and prevent issues from arising. 

Change the cabin air filter – The cabin air filter helps prevent dust, pollen, and other debris from entering the cabin and clogging the AC system. A dirty or clogged cabin air filter can reduce the airflow and cooling efficiency of the AC system. Changing the cabin air filter every 12,000 to 15,000 miles or once a year is recommended.

Inspect the belts and hoses – The belts and hoses in the AC system can wear out over time and develop cracks or leaks. Regular inspection can help detect any issues before they cause significant problems.

Check the refrigerant level – The refrigerant is the substance that cools the air in the AC system. A low refrigerant level can reduce the cooling performance and cause the compressor to overwork. It is recommended to check the refrigerant level every 12,000 to 24,000 miles or every two years.

Clean the condenser – The condenser can become clogged with dirt, debris, and bugs, reducing its ability to release heat from the refrigerant. Regular cleaning with a soft brush or compressed air can help maintain efficiency.

Run the AC system regularly – Running the AC system regularly can help keep the system lubricated and prevent the seals from drying out.

Have the AC system serviced regularly – Have the AC system inspected and serviced by a qualified mechanic every two years or as the manufacturer recommends.

Is your air conditioner ready for the summer season?

Regular maintenance and servicing of the AC system can help prevent any of these problems from occurring in the first place. It’s the best way to ensure your vehicle is ready for whatever Colorado weather dishes out. 

When was the last time you had your air conditioner inspected?

Get ready for the summer – book your maintenance visit now. 

Understanding the Ins and Outs of Car Engine Repair

by

At the center of your vehicle, the very heart of what makes your car operate, is the engine. Without an engine, your car would cease to go. 

A car engine has dozens of pieces, including:

  • Engine block
  • Combustion chamber
  • Cylinder head
  • Pistons 
  • Crankshaft
  • Camshaft
  • Timing belt
  • Valves 
  • Fuel injectors
  • Spark plugs
  • Oil pan
  • Manifold
  • Piston rings
  • Flywheel

While it may seem easy to you – turn the key, and it works, a car engine is a complex machine designed to convert energy into mechanical energy, allowing the entire vehicle to function. 

When it works well, it’s one of the most dynamic inventions we live with each day. However, if one of those components goes bad at any point, it can lead to problems. 

Car engine repair keeps your engine running smoothly for the life of your vehicle. 

Understanding the Ins and Outs of Car Engine Repair

How a car engine works

A car engine is an intricate machine that converts fuel into mechanical power. Without this, your vehicle would never move. It consists of several parts that work together in a complex sequence to keep the car running. 

Most common car engines use an internal combustion engine. It burns fuel inside a cylinder to create power. This engine can run on gasoline, diesel, or other fuels. The motor contains several cylinders, each with a piston that moves up and down.

The intake stroke is the first step in the engine cycle. The piston moves down, which creates a vacuum in the cylinder. This vacuum pulls air into the engine through an intake valve. Some engines also have a turbocharger or supercharger that compresses the air, which increases the engine’s power output.

In the compression stroke, the piston moves back up and compresses the air and fuel mixture. This mixture is highly combustible and needs to be compressed to increase the pressure and temperature inside the cylinder. The compression ratio is critical in determining the engine’s efficiency and power output.

In the ignition stroke, the spark plug fires, which ignites the air and fuel mixture. This explosion creates a rapid expansion of gasses, which pushes the piston down. The energy released by the explosion powers the engine.

In the final exhaust stroke, the piston moves back up, forcing the spent gasses out of the cylinder through an exhaust valve. The gasses are routed through the exhaust system and released into the atmosphere.

The valvetrain is the system that controls the intake and exhaust valves. It is responsible for opening and closing the valves at the appropriate times. The camshaft, driven by the crankshaft, controls the valve timing. The camshaft has lobes that push on the lifters, opening and closing the valves.

The fuel system is responsible for delivering fuel to the engine. The most common fuel system type is a fuel injection system, where the fuel is pressurized and sprayed into the engine through a nozzle. The engine’s computer controls the amount of fuel injected into the engine, which monitors several sensors to determine the optimal fuel-air mixture.

The cooling system is essential for preventing the engine from overheating. The engine generates a lot of heat, which can damage the internal components. The cooling system circulates coolant through the engine to absorb the heat and transfer it to the radiator. The radiator dissipates the heat into the atmosphere.

Keeping your car engine running smoothly

Now that you have a deeper understanding of how a car engine works, it may be easier to understand how maintenance plays into keeping it running smoothly. It’s an intricate machine that works well when everything is in good operating condition but can quickly fail when something goes wrong. 

Car manufacturers and repair shops all agree you should keep certain maintenance items on your calendar throughout the year. They include:

Regular Oil Changes – Regular oil changes are one of a car engine’s most critical maintenance tasks. The oil lubricates the engine’s moving parts and helps to keep it clean. Over time, oil breaks down, and its ability to lubricate the engine diminishes. Changing the oil and filter every 3,000 to 5,000 miles is recommended.

Air Filter Replacement – The engine’s air filter prevents dirt and debris from entering the engine. Over time, the filter can become clogged, reducing airflow and decreasing performance. A dirty air filter should be replaced every 12,000 to 15,000 miles.

Spark Plug Replacement – Spark plugs ignite the air-fuel mixture in the engine cylinders. Worn or dirty spark plugs can cause misfires, reduced performance, and reduced fuel economy. Replace spark plugs every 30,000 to 100,000 miles, depending on the plug type and the vehicle’s use.

Coolant System Flushing – The engine’s coolant system helps to regulate the engine’s temperature. Over time, coolant can become contaminated and lose its effectiveness. Flushing the coolant system every 30,000 miles or every 2 to 3 years helps to prevent overheating and engine damage.

Timing Belt Replacement – The timing belt connects the crankshaft and camshaft and keeps the engine’s valves and pistons in sync. A broken timing belt can cause severe engine damage. Replace the timing belt every 60,000 to 100,000 miles, depending on the vehicle’s manufacturer’s recommendation. Don’t wait until it breaks; keep this on your to-do list and replace it before it wears down.

Regular Tune-Ups – Regular tune-ups can help keep the engine running smoothly and efficiently. A typical tune-up includes replacing spark plugs, inspecting ignition wires, and checking the fuel and air filters.

Proper Driving Habits – It’s not just regular maintenance that keeps your engine in good working condition. Proper driving habits, such as avoiding hard acceleration and deceleration and maintaining a steady speed, can help reduce engine wear and tear.

What condition is your engine in? 

It doesn’t take a lot of work to keep your car’s engine running smoothly. Instead, it takes regular inspections and periodic maintenance.

The Exhaust System: How It Works and Why It Matters

by

Your car’s exhaust system has an important job. It moves burnt air/fuel mixture out of the engine. Without a working exhaust system, you would drive a noisy car. You would also smell the fumes inside your car. 

Have a performance issue? It may stem from the exhaust system. The more you learn about it, the better you’ll be at maintaining it. 

How the exhaust system works on a vehicle

The exhaust system is a vital component of a vehicle, responsible for carrying away the harmful byproducts of the engine’s combustion process. 

The exhaust system is designed to remove the waste gasses produced during the engine’s combustion process and redirect them out of the vehicle. When the fuel and air mixture in the engine’s combustion chamber is ignited, it produces gasses, including carbon dioxide, nitrogen oxides, and unburned hydrocarbons. If these gasses remained in the engine’s cylinders, they would cause damage and decrease efficiency. The exhaust system removes them and redirects them out of the vehicle.

The exhaust system comprises several components that work together to achieve the basic function. These include:

The Exhaust System: How It Works and Why It Matters

Exhaust Manifold – This exhaust manifold connects the engine’s cylinders to the exhaust pipe. The exhaust manifold collects the waste gasses produced by the engine’s combustion process and directs them to the exhaust pipe.

Exhaust Pipe – The long metal tube carries the waste gasses from the engine’s cylinders to the muffler. It is usually made of steel and is designed to withstand high temperatures and corrosive exhaust gasses.

Catalytic Converter – The catalytic converter is responsible for reducing the emissions of harmful gasses. It converts the gasses into less harmful ones, such as carbon dioxide, water vapor, and nitrogen.

Muffler – The muffler reduces the noise produced by the engine. It creates a series of chambers that absorb the sound waves the engine’s combustion process produces.

Exhaust Tip – The exhaust tip is the visible part of the exhaust system and is usually made of chrome or stainless steel. It is designed to give the vehicle a sporty look and protect the exhaust pipe from damage.

The exhaust system works in a series of stages. In the first stage, the exhaust manifold collects waste gasses from the engine’s cylinders. These gasses are directed to the exhaust pipe, which carries them to the catalytic converter.

The catalytic converter converts harmful gasses into less harmful ones through a chemical reaction. The gasses pass over a surface coated with precious metals such as platinum, palladium, and rhodium, which cause a chemical reaction that converts them into less harmful ones.

From the catalytic converter, the gasses pass through the muffler, which reduces the noise produced by the engine’s combustion process. 

Finally, they exit through the exhaust tip at the back of the vehicle.

Why an exhaust system is important

While it may seem obvious, an exhaust system is important for a variety of reasons. The exhaust system plays a crucial role in the engine’s function and in ensuring the safety of passengers and the environment. 

It removes harmful gasses – The exhaust system’s primary function is to remove the harmful gasses produced during the engine’s combustion process. These gasses include carbon monoxide, nitrogen oxides, and hydrocarbons, which can be toxic and dangerous to the passengers if they accumulate in the cabin. The exhaust system redirects these gasses out of the vehicle, making it safer to drive.

It improves engine performance – The exhaust system also helps improve the engine’s performance by providing a way to expel waste gasses quickly and efficiently. If the exhaust system is not functioning correctly, it can build up pressure in the engine, leading to decreased performance and fuel efficiency.

It reduces noise – The exhaust system also plays a vital role in reducing engine noise. The muffler is specifically designed to dampen the sound waves the engine’s combustion process produces. Without the muffler, the noise made by the engine would be much louder and more unpleasant.

Environmentally friendly – The exhaust system is also essential for protecting the environment by reducing the engine’s harmful emissions. The catalytic converter helps convert the harmful gasses the engine produces into less harmful ones. This helps reduce the vehicle’s carbon footprint and makes it more environmentally friendly.

It keeps your car in compliance with regulations – Specific regulations mandate using an exhaust system on vehicles to reduce harmful emissions. Failure to comply with these regulations can lead to fines and other legal consequences.

What can you do to keep your car’s exhaust system in good working condition

Properly maintaining your car’s exhaust system is essential to keep it in good working condition. What can you do to ensure it remains in good shape:

Schedule regular inspections – Inspect your exhaust system regularly, ideally every 12 months or every 15,000 miles, to identify any potential issues before they become bigger problems.

Check for leaks – If you hear a loud or unusual noise coming from your car’s exhaust system, it could be a sign of a leak. Check for any visible cracks, holes, or rust on the pipes and muffler, and have them repaired or replaced as soon as possible.

Replace worn-out parts – Over time, parts of your exhaust system, such as the muffler, catalytic converter, or oxygen sensor, can wear out and need replacing. Replace these parts promptly when required.

Avoid driving over rough terrain – Driving on uneven terrain or hitting speed bumps and potholes can cause damage to your car’s exhaust system. Avoid driving on rough terrain as much as possible.

Use the right fuel – Using the wrong type of fuel or poor quality gasoline can build-up of harmful residues that can damage your car’s exhaust system. Always use the type of fuel recommended by your car manufacturer and buy from reputable gas stations.

Keep your engine tuned – A poorly tuned engine can produce more exhaust gasses, putting more stress on your exhaust system. Regularly tune your engine to ensure it runs efficiently and reduces emissions.

Is your car’s exhaust system in good working condition?

Regular inspections, prompt repairs, and proper maintenance are essential to keep your car’s exhaust system in good working condition. Following the tips above can help prevent damage and prolong the life of your car’s exhaust system.

  • How fast you’re driving
  • The maintenance of your vehicle
  • How old your brake system is
  • What weather conditions are currently
  • The make and model of the vehicle

Inherently we know that our cars will stop differently in July than in January. Hot streets create a different experience than a road covered in ice and snow. 

And while you might not think about your stopping power every time you jump behind the wheel, you might think about safety. You have a lot going on inside your vehicle. Safety is your number one concern. 

This is why brake maintenance should also be top of your list. Brakes keep you safe. Your ultimate goal is to improve stopping power to lower your risk.

What to know about stopping power

What do you need to know about your brakes stopping power? For most drivers, it’s a simple process. Tap on the brakes; the car slows down until it ultimately comes to a stop. 

How to Improve Stopping Power and Safety with Brake Maintenance

But there’s more to it than that. 

Stopping power measures what it takes to bring the vehicle to a stop. It’s the stopping distance as you face everyday driving conditions. Ultimately it depends on:

  • How well the brakes work when you tap on the brake pedal
  • How well a vehicle reacts when the brake pedal is pressed
  • Your perception of driving conditions
  • How well you react when you sense a change in driving conditions

In most cases, it takes about three-quarters of a second to perceive a change in driving conditions, and another three-quarters of a second to react and tap the brake pedal to start the braking process. That’s 1.5 seconds before the brakes start doing their job. At a standard 60 mph, your car can travel as much as 120 to 140 feet in that 1.5 seconds.

Once you start the reaction process, it’s the vehicle’s turn takeover. Dry pavement conditions will provide more stopping power than wet pavement. It can easily double or even triple the space needed to bring your vehicle to a complete stop. 

All of this is with a car in good working condition. Ignoring regular brake maintenance can increase the time needed to stop, putting you, your passengers, and those around you at risk.  

It’s time for brake maintenance

As you continue to drive your car, you’ll get comfortable with how it works. You’ll develop a relationship with it, understanding when it’s trying to communicate with you. 

Maybe you hear a strange noise you’ve never heard before. A light flashes on the dashboard. Or an odor becomes apparent when you step on the brakes. 

Your vehicle was designed with safety systems to alert you when problems arise. Rarely will systems fail on a dime. Instead, warning signals will be sent, alerting you to potential problems.  

If you notice these early, you have time to do something about them. Your brakes are one of the most important systems in your car. Watch for any of these problems. Then take action as soon as possible. 

Noisy brakes – Brake pads are the most commonly replaced items within the brake system. The pads are designed with a warning marker to alert you the brake pads are wearing down. You can’t miss this high-pitched squeal. Every time you step on the brake pedal, that squeal will remind you it’s time to replace your brake pads. Ignore it, and the noise will worsen. Wait too long, and it could do more damage to the brake system, possibly warping the rotors. This will increase your repair bill once you bring it in for replacement. 

Smelly brakes – It’s not based on sound alone; you’ll notice a smell along with it. As brake pads wear down and possibly impact the brake caliper, it may begin to produce a scent you won’t be able to ignore. It may be a chemical smell as the wear layer burns down, or a burning smell as the brakes heat up. If you notice it, it’s time to bring them in for maintenance. 

Soft brakes – You can’t miss this soft, spongy feel when you press down on the brake pedal. You’ll press down further to get the same job done. Moisture can accumulate in the brake fluid reservoir, allowing the brake fluid to boil from the heat generated as you drive. Air in the brake’s hydraulic system can delay the reaction time between pushing on the brake pedal and stopping. 

Hard brakes – The opposite is also true. If you push down on the brake pedal and it’s harder than usual, it’s a sign of misaligned brakes or a brake booster no longer functioning correctly. 

Tires – The reason you have trouble stopping might not be your brakes at all. Instead, it could be a tire that can no longer function as designed. When tire tread is too thin or too worn, it doesn’t have the traction to bring your vehicle to a stop. It won’t have the “bite” necessary to grip the road. Bad driving conditions only accelerate this problem. That’s why it’s good to have them checked occasionally. 

Are your brakes well maintained? 

Good brake maintenance starts with getting to know your car. It’s about feeling how it runs when operating well so that you know when something is off. 

There’s no denying that one of the most critical systems on your vehicle is your brakes. If they aren’t working correctly, your stopping power can quickly diminish. 

When was the last time you had your brakes checked and maintained? If it’s been a while, now may be the time. With quick servicing, our experts will ensure your vehicle is ready to face the challenges of the road ahead, no matter what the Colorado weather throws our way. 

Tune-Up Tips: How to Keep Your Car Running at its Best

by

If you’ve priced new cars lately, you might have been shocked. The average luxury car is now up to $67,050, with non-luxury lines hovering around $44,584. 

That’s a lot of money to invest in something that depreciates the moment you drive it off the lot. The better you care for it, the longer it will run. 

How do you keep your car running at its best? Regular maintenance and tune-ups will ensure your investment stays operating well throughout its life. 

Use these tips to help you keep car maintenance at the forefront of your mind.

What is a tune-up?

A tune-up is a regular maintenance visit with a mechanic to keep it running smoothly and efficiently. It typically involves checking and adjusting various systems and components to ensure they are operating optimally.

With over 30,000 parts, there are many components to track and take care of. Luckily, all vehicles are built similarly with comparable systems and components. Tune-ups vary depending on the make and model of the vehicle, as well as its age and condition, but generally include:

Tune-Up Tips: How to Keep Your Car Running at its Best

Spark plugs – they deliver an electrical spark to ignite the fuel-air mixture in the engine. Over time, spark plugs can become worn and misfiring can occur, causing decreased fuel efficiency and increased emissions.

Ignition system – this includes the spark plug wires, distributor cap, and rotor. These components can wear out over time, leading to misfiring and decreased performance.

Air filter – the air filter helps prevent debris from entering the engine, which can lead to damage. A dirty or clogged air filter can also reduce fuel efficiency and performance.

Fuel system – this includes the fuel filter, fuel pump, and fuel injectors. These components help to deliver fuel to the engine and can become clogged or wear out over time, causing decreased performance and increased emissions.

Motor oil and oil filter – engine oil helps lubricate the engine and protect it from wear. A regular oil change and oil filter replacement can help to keep the engine running smoothly and prevent damage.

Emissions control systems – this helps reduce the amount of pollutants released into the environment. They include the oxygen sensor, catalytic converter, and other components, and can become clogged or worn out over time, causing increased emissions and decreased performance.

While these are just a few of the many parts and systems located on your vehicle, it’s important to note that a car tune-up can help to improve a vehicle’s fuel efficiency, performance, and emissions. Tune-ups help to identify and resolve potential problems before they become more serious. 

However, it’s equally important to note that the frequency and type of tune-ups required will vary depending on the make and model of the vehicle, as well as its age.

Why do tune-up requirements change as a car ages?

As a car ages, things start to change. Parts wear down at different rates. Systems rely on a variety of functions, some old and some new. All of that can stress how the vehicle operates and cause additional issues.  

While you should continue with tune-ups as your car ages, how a tune-up is defined and the repair work that needs to occur will vary and change along with it.  

As components age, they can become worn or damaged, reducing their efficiency and performance. For example, spark plugs can become dirty, ignition components can wear out, and fuel and air filters can become clogged. These issues can lead to decreased fuel efficiency, reduced performance, and increased emissions. Regular tune-ups are needed to maintain optimal performance.

Advances in technology can also affect the tune-up requirements for a vehicle. As engines have become more sophisticated, the number of spark plugs, or the use of traditional distributors, has changed. Newer vehicles may use electronic fuel injection, which requires different maintenance procedures than older vehicles that use carburetors.

Emissions requirements have also changed over time, requiring different tune-up procedures to maintain compliance. Catalytic converters and oxygen sensors are the perfect examples, with components now required to control emissions at today’s optimal levels. Your car needs evaluation to fix what it can, and optimize based on function. 

Why you should rely on a professional for a tune-up

Some will say there are many things you can do yourself in order to ensure your car is tuned-up and in excellent working condition. We agree! This is about you keeping a watchful eye over how your car operates every single day.

The Role of Sensors in Your Car’s Anti-Lock Brake System: Understanding How They Work

by

Few systems on your vehicle are as critical as the brakes. They help keep your car under control. They help keep you safe. 

Since brakes were first developed, designers have worked to make them better. 

The very first cars were equipped with simple braking systems consisting of a lever or pedal connected to the wheels. These early brakes were not very effective, and they often failed to stop the car in a timely manner. With so few cars on the road, it had little effect. But it did spawn the next generation of brakes.

In the early 20th century, new technologies improved the performance of brakes. Drum brakes were introduced, which used brake shoes to press against the inside of the drum wheel. This design was more effective than the earlier mechanical brakes, and became the standard for most cars.

In the 1950s and 1960s, disc brakes were phased in. Disc brakes use a rotor attached to the wheel with brake pads that press against the rotor to slow down the car. This design is more effective than drum brakes and provides better stopping power. Disc brakes have now become the standard for most cars, and are used on both the front and rear wheels.

With more advanced materials and computer-aided design, braking systems continue to evolve. Today, you’ll find cars equipped with advanced braking technologies, including anti-lock braking systems (ABS), electronic brake force distribution (EBD), and brake assist (BA). These systems use sensors and computer-controlled actuators to optimize braking performance and improve safety.

What does the future hold? Electric vehicles (EVs) are bringing in new brake systems specifically designed for EVs. These systems use regenerative braking, which captures the energy generated by the car’s brakes and uses it to recharge the battery.

If there is a way to make the braking system safer, car designers are finding ways to implement the technology. Sensors are and will remain an essential part of overall car design. 

The Role of Sensors in Your Car's Anti-Lock Brake System: Understanding How They Work

The role of anti-lock brakes

You don’t have to go any further than the name to understand the role anti-lock brakes play in the braking system. Anti-lock brakes are designed to prevent the wheels from locking up. If you’ve ever experienced this on icy roads, you understand how dangerous it can be. Anti-lock brakes avoid skidding or loss of control. It helps decrease the braking distance to improve overall safety. 

The ABS keeps the tires connected to the road. Before ABS, pressing down hard on the brake pedal could lock the steering wheel and cause the wheels to skid. When you lose traction, you lose control.

ABS uses sensors to monitor the rotation of each wheel. It detects slippage, skidding, or wheel lock. When it encounters it on one or more wheels, the electronic control unit will send a signal to the hydraulic control unit, releasing braking pressure to improve the grip. With the lock position corrected, brake pressure is reapplied to keep the wheel connected and bring the car to a complete stop. 

How an anti-lock brake sensor works  

Anti-lock sensors are located at each wheel hub. These sensors constantly monitor the rotation of each wheel throughout the drive. They monitor every aspect of wheel cycling to see if any of them skid or lose control. 

Speed sensors calculate the revolutions and continuity between each wheel. If it detects differences, the ABS engages and takes over the braking. 

A speed sensor consists of a magnet wrapped in a coil, attached to a sensor ring connected to the CV joint hub. As these two meet, they create an electrical field that measures the number of pulses per second created between each coil and sensor ring. This converts to a digital signal that is transmitted to the ABS. The controller counts the pulses and evaluates when to control the braking. 

What can go wrong with the anti-lock brake sensors

Different cars will have different anti-lock brake sensor configurations, with most of today’s vehicles having a sensor attached to each wheel. With more parts means there are more chances for a component to fail, activating a potential problem that can impact you while you drive. 

With most vehicles, technology creates precise measurements and has a dynamic way of alerting you to potential problems. When an ABS sensor fails, it will warn you in several ways. 

The ABS light comes on

The most apparent alert system will occur right on your dashboard. The ABS light will come on, alerting you it’s detected an issue with the ABS. Think of the ABS light as a similar warning signal to the check engine light. It’s a check system that alerts you to minor changes, giving you plenty of time to schedule a visit with your mechanic to determine where the problem lies. Never ignore warning signals. They’re there for a reason. 

Braking changes

The goal for any driver should be to avoid heavy braking conditions whenever possible. Slamming on the brakes is never good, putting you, your passengers, and your car at risk. That said, systems like ABS are designed for unavoidable situations where hard braking is necessary. Over time, you may notice changes in the way your brakes respond. Does it take longer to react? Do you see tiny slips in what used to be flawless recovery? It might be an indicator of a problem with an ABS sensor. Since the ABS is crafted from just a few components, the problem may lie within the controller or the sensors. A mechanic can test both and find out exactly where the problem lies. 

Less stability under poor driving conditions

We’ve had our share of bad driving conditions this year. The ice and snow have lingered for what seems to be a long time. Over time, you’ve developed a sense of how your car performs under different weather conditions. This is where it pays to focus on your car’s performance. A properly functioning ABS will minimize any traction loss. If you experience any traction loss or feel a slight slippage, it might indicate an ABS sensor failing. This is often caused by a problem within the module, or a component of the sensor that needs replacing. 

The role of the anti-lock brake sensor – is yours working? 

Today’s modern conveniences keep us safer on the road. It’s also possible for more problems to occur over time as things wear down. 

When was the last time you had your car inspected? Schedule an inspection today if you think you have a problem with an anti-lock brake sensor. 

It’s the best way to keep you safe and out of harm’s way. 

Auto Repair and Suspension: How to Improve Handling and Ride Comfort

by

You expect a smooth, comfortable ride when you hop in your vehicle. If you notice every bump and dip in the road, it’s a sign something is going on with your vehicle’s suspension. How do you improve handling and ride comfort?  

How suspension controls handling and ride comfort

The suspension system is crucial in controlling handling and ride comfort. It is responsible for absorbing shocks and vibrations from the road surface and maintaining contact between the tires and the road. Without this, you wouldn’t have stability and control of the vehicle.

The suspension system controls:

Handling – The suspension system helps maintain the vehicle’s stability while it is in motion. It does this by controlling the movement of the wheels and keeping them in contact with the road. This helps the driver maintain control even in rough or uneven terrain.

Ride comfort – A well-designed suspension system can provide a comfortable ride even on rough roads, minimizing the discomfort felt by passengers.

Auto Repair and Suspension: How to Improve Handling and Ride Comfort

Weight distribution – The suspension system also helps distribute the vehicle’s weight evenly, improving handling and ride comfort. When the weight is evenly distributed, the car is less likely to sway or bounce around as you’re driving down the road.

Cornering – When the vehicle corners, the suspension system keeps the body of the vehicle level, which helps to maintain traction and stability.

Braking – The suspension system prevents the wheels from locking up and allows the vehicle to come to a stop smoothly and safely.

Improving your vehicle’s ride quality can make your driving experience more comfortable and enjoyable and even reflect your personality. As a driver, you may have unique preferences for how your vehicle handles and the overall driving experience.  

How you can improve the right quality

Technology is the key to today’s driving experience. We’ve been increasing every aspect of the everyday commute in just a few short years. Cars today help you drive, navigate, and park. They alert you to potential problems long before they impact your drive. 

Yet you can’t rely entirely on technology to alert you of minor issues that can impact your comfort. Some of that comes from scheduling regular maintenance. An auto repair shop is critical to ensuring your car’s longest lifespan. For the suspension to be in top condition, pay attention to:

Check tire pressure – A smooth ride depends on how well your tires connect with the road. Make sure your tires are inflated to the recommended pressure. Overinflated or underinflated tires can lead to a harsh ride and poor handling.

Replace worn-out shocks and struts – Shocks and struts help absorb bumps and vibrations from the road, providing a smooth and comfortable ride. When worn out, the vehicle may bounce or jolt excessively, making the ride uncomfortable and potentially causing motion sickness. Shocks and struts also play a crucial role in the handling and stability of the vehicle. They help the wheels stay in contact with the road, providing traction and grip during acceleration, braking, and cornering. When worn out, the vehicle may feel unstable, wander or drift on the road, or even sway or roll during turns. Replacing worn-out shocks and struts can improve the handling and stability as well as restore the smoothness and comfort of the ride.

Check wheel balance and alignment – Misaligned wheels can cause uneven tire wear, poor handling, and a rough ride. Wheel balancing involves adjusting the weight distribution of the tire and wheel assembly to ensure that it rotates evenly around its axis. When a tire and wheel assembly is incorrectly balanced, it can cause vibration, uneven tire wear, and handling problems. On the other hand, wheel alignment involves adjusting the angle and position of the wheels relative to the vehicle and the road surface. When wheels are misaligned, they can cause a range of problems, including uneven tire wear, poor handling, and decreased fuel efficiency. Each process helps improve handling, reduce tire wear, and improve fuel efficiency.

Install high-quality tires – Higher quality tires can significantly improve the driving experience by providing better traction, handling, comfort, and safety. High-quality tires typically have better tread designs and compounds that provide superior grip on the road, especially in wet or slippery conditions. This improved traction can lead to better acceleration, braking, and cornering, making the vehicle more stable and responsive. They also tend to have more advanced construction and materials, resulting in a more precise and consistent handling experience. With better feedback and control, the vehicle will feel more connected to the road, allowing the driver to maneuver more confidently.

Reduce vehicle weight – Too much weight in a vehicle can significantly impact the suspension system, which is responsible for supporting the weight of the car and its occupants, as well as absorbing shocks and vibrations from the road. When a vehicle is overloaded, the suspension may sag or compress beyond normal limits, causing the ride height to lower. This can lead to reduced ground clearance, decreased handling and stability, and increased tire wear.

It can also strain the suspension components, such as springs, shocks, and struts. This can cause them to wear out more quickly or even fail prematurely, compromising the vehicle’s safety. And when a vehicle is overloaded with extra sports equipment and weekend to-do items, it may be more challenging to control and handle, especially during sudden maneuvers or emergencies. The suspension system may not effectively absorb shocks and vibrations, causing the vehicle to bounce, sway or roll more than usual.

Improve handling today – your car will thank you

What will it take to improve how your vehicle handles on the road? A lot of it is based on your suspension system. 

If you take care of your car and schedule regular maintenance visits with your auto repair shop, you’re more likely to keep your vehicle in good working condition for life.
