The Art of Troubleshooting Car Engine Performance Issues

by

Heading out onto the open road is always an exciting experience. You’re dreaming about your final destination. You have work chores in mind, ticking things off to complete during your busy day ahead. 

What you’re not prepared for is car trouble. If you’re having car engine performance issues, your entire day may be spent dealing with the problem. 

Owning a car comes with its fair share of joys and challenges, and one of the most frustrating challenges is when your car’s engine isn’t performing as it should. But fear not! We can help you troubleshoot the most common engine performance issues. 

The Engine Won’t Start

Picture this: you’re ready to head out for an important meeting or a long-awaited road trip, and your car refuses to start. Don’t panic! Start by checking the basics. 

Are your lights, radio, and other electrical components working? If they are, then your battery is likely not the issue. If they’re not working, a dead battery might be the culprit, and jump-starting your car could do the trick.

If the battery isn’t the issue, move on to checking the starter and the ignition switch. A clicking noise when you turn the key might indicate a faulty starter. If you hear nothing at all, the ignition switch could be to blame. 

It’s always a good idea to have a set of jumper cables, a spare key, and the number of a reliable tow service in your back pocket – just in case.

The Art of Troubleshooting Car Engine Performance Issues

The Check Engine Light Turns On

Ah, the infamous check engine light – the little yellow indicator that can send shivers down any driver’s spine. First, take a deep breath. The check engine light can be triggered by a multitude of issues, ranging from something minor to more serious problems. 

The first step is to retrieve the trouble codes from your car’s onboard diagnostic (OBD) system. You can do this by using an OBD-II scanner, which is available at auto parts stores or online.

Once you have the trouble codes, you can start narrowing down the issue. Keep in mind that the code doesn’t always point directly to the faulty component; it’s more like a clue in a detective story. You might need to do some further investigation or seek professional help if the problem seems beyond your expertise.

The Engine is Overheating

Seeing your temperature gauge spike into the red zone can be nerve-wracking, but don’t hit the panic button just yet. An overheating engine can be caused by various factors, such as a faulty thermostat, a malfunctioning radiator fan, or a coolant leak.

Quick Fix: If you notice your temperature gauge climbing, turn off your air conditioning and turn on the heat to high. This might sound counterintuitive, but it helps transfer heat away from the engine. Pull over as soon as it’s safe and let the engine cool down before opening the hood.

To prevent overheating, regularly check your coolant levels and look for any visible leaks. If you’re comfortable, you can also inspect the radiator hoses for cracks or bulges. Keep in mind that a more complex issue might require a visit to your trusted mechanic.

The Engine is Stalling

Dealing with a stalling engine can make any driver feel like they’re on a roller coaster of frustration. Stalling can occur for various reasons, such as a clogged fuel filter, a malfunctioning oxygen sensor, or even a problem with the spark plugs.

DIY Tip: Start by checking your air filter. A dirty air filter can disrupt the air-fuel mixture, leading to stalling. If your air filter looks like it’s seen better days, replacing it could potentially solve the issue.

If the problem persists, consider when the stalling occurs. Is it more likely to happen when idling, accelerating, or decelerating? This information can help you narrow down the possible causes and give your mechanic a head start in diagnosing the problem.

You Notice Steam or Smoke

Seeing steam or smoke billowing from your car’s engine can instantly make you panic. But before you jump to conclusions, let’s break it down. Smoke can be white, black, or blue, and each color might point to a different issue.

White Smoke: If your engine is emitting white smoke, it could be a sign of a coolant leak. This could mean a blown head gasket or a cracked engine block, both of which are serious problems that require immediate attention.

Black Smoke: Black smoke usually indicates the air-fuel mixture is too rich. This can be caused by a clogged air filter, a faulty fuel injector, or a malfunctioning oxygen sensor.

Blue Smoke: Blue smoke is often a sign of burning oil. This could be due to worn piston rings, valve seals, or other internal engine components.

Addressing these issues might involve replacing parts, fixing leaks, or even rebuilding parts of your engine. In any case, it’s best to consult a professional to accurately diagnose and resolve the problem.

You Hear a Funny Noise

Cars have their own language of sounds, and as a driver, it’s essential to pay attention to what your car is telling you. If you hear an unusual noise, don’t just crank up the radio to drown it out – listen closely. A clunking noise could indicate a problem with your suspension, while a squealing noise might point to worn-out brake pads.

Pro Tip: If you hear a knocking noise coming from under the hood, it could be a sign of engine trouble, such as detonation or worn-out bearings. It’s crucial to address this promptly, as engine issues can escalate quickly if left unchecked.

If you’re uncomfortable diagnosing the noise, don’t hesitate to take your car to a professional. They have the experience and tools to pinpoint the source of the noise and provide a proper solution.

Ignoring Oil Changes and Coolant Levels

Skipping oil changes and neglecting coolant levels might seem like time-saving measures, but in reality, they can lead to major engine performance issues down the road. Engine oil lubricates and cools your engine’s moving parts, while coolant prevents your engine from overheating.

Vital Reminder: Regular oil changes and checking coolant levels are simple yet crucial tasks that can extend the lifespan of your engine and prevent costly repairs.

There’s Water in the Engine

Water and engines don’t mix well, so if you suspect water has found its way into your engine, take immediate action. This can happen if you’ve driven through deep water or your engine has been exposed to heavy rain.

What to Do: If you’ve driven through water higher than the bottom of your vehicle, don’t attempt to start the engine. Have your car towed to a professional to assess the damage. Starting the engine with water in the intake system can lead to hydrolock, which can cause severe engine damage.

How’s your car engine performance? 

The art of troubleshooting car engine performance issues involves a combination of observation, investigation, and, when needed, seeking professional help. While it’s tempting to become a DIY hero, remember that some problems are best left in the hands of experienced mechanics. 

Regular maintenance, a keen ear for unusual sounds, and a bit of patience will go a long way in keeping your engine running smoothly and your stress levels in check. And with these tips in mind, you’ll be ready to handle it like a pro!

Why a Head Gasket Fails and What to Do About It

by

You don’t have to understand car mechanics to know that a blown head gasket is bad news. When a head gasket fails, it impacts the entire engine. 

Luckily, it isn’t a common problem. What’s more, it’s an issue you don’t have to face. In general, head gaskets are robust parts that usually last 100,000 miles or more. This is where regular maintenance comes into play. If you partner with a mechanic who performs routine maintenance, you’ll be alerted to issues before they begin. It allows you to fix and replace parts before they add into the mix. 

With that in mind, let’s dive in and learn more about what head gaskets do. 

What is a head gasket 

A head gasket is a critical component in an internal combustion engine, sealing the cylinder head and engine block together. It plays a vital role in maintaining proper compression and preventing coolant or engine oil leaks into the combustion chamber. This thin yet robust gasket separates different fluids and gasses flowing through the engine, contributing to its overall efficiency.

How a head gasket works

The head gasket is positioned between the engine block and the cylinder head, sealing the combustion chamber. When the engine runs, the head gasket is subjected to tremendous heat and pressure as it experiences the force of each piston’s compression stroke. This compression creates a tight seal between the engine components, allowing them to work harmoniously.

Why a Head Gasket Fails and What to Do About It

What happens when a head gasket fails

Unfortunately, head gasket failures are common, and when they occur, they can lead to severe consequences for your engine. 

When the head gasket fails, the seal between the engine block and cylinder head is compromised, resulting in leaks. This allows mixing of vital fluids. Once this happens, it can cause a drop in engine performance and, if left unaddressed, lead to catastrophic engine damage.

What causes a head gasket failure

Several factors can contribute to the failure of a head gasket. Let’s explore some of the common causes:

Pre-ignition

Pre-ignition occurs when the air-fuel mixture in the combustion chamber ignites prematurely, creating an intense spike in pressure. This sudden pressure can stress the head gasket excessively, causing it to fail over time.

Overheating 

Excessive engine temperatures can cause the head gasket to warp or crack, leading to leaks. Overheating is often a result of coolant system issues, such as a faulty thermostat, water pump, or coolant leak.

Pushing the engine to its limits

If you consistently push your engine to its maximum performance levels, it can put additional strain on the head gasket, eventually causing it to fail. When first starting out in the morning, give your car a chance to warm up before revving the engine. 

Think defensive driving rather than offensive. You’re not on a race track; your car is simply trying to get you from one place to another. Your car will thank you when you learn to take it easy. 

Poor gasket design

Head gasket failures can sometimes be attributed to inferior quality or poorly designed gaskets. Some may be crafted with cheap materials or not mesh with other internal parts. 

High-quality gaskets, installed correctly, are more likely to withstand the demands of engine operation.

How head gasket failure shows up

Detecting head gasket failure early is crucial to prevent further damage to your engine. Here are some common signs to look out for:

Loss of power

A failing head gasket can lead to a loss of engine power, making acceleration sluggish and reducing overall performance.

Overheating

If your engine is constantly overheating or frequently running hot, it may be a sign of head gasket failure, as the compromised seal leads to coolant leaks and inefficient cooling.

Oil contamination

A faulty head gasket can allow engine oil to mix with the coolant, resulting in a milky appearance in the oil or coolant reservoir.

External leaks

Leaking coolant or engine oil around the engine block and cylinder head area can indicate a head gasket issue. This is where a quick walk around your vehicle can alert you to potential problems. If you notice something, you’ll have a chance to bring it in before the situation escalates. 

White smoke

Excessive white smoke from the exhaust pipe, especially when the engine is warm, could be a sign of coolant entering the combustion chamber and burning along with fuel.

Preventing head gasket failures

While head gasket failures can be inconvenient and expensive, there are steps you can take to minimize the risk:

Regular Maintenance

Get to know your owner’s manual. Follow the manufacturer’s recommended maintenance schedule, including regular coolant system inspections and fluid changes. Proper maintenance can help identify potential issues before they escalate.

Avoid Overheating

Monitor your engine’s temperature gauge and address any overheating issues promptly. Those little dashboard icons are trying to tell you something. When they illuminate, don’t ignore them. Schedule a service appointment soon. 

Use Quality Gaskets and Parts

Invest in high-quality parts from reputable manufacturers when replacing the head gasket or any engine components. This can significantly improve the gasket’s longevity and reduce the chances of premature failure. 

Chances are you won’t be doing the work yourself, and instead will look to an experienced mechanic to do the job for you. This is where it pays to have a partner in keeping your vehicle in good repair. You’ll know they use reputable brands for the parts they install. You’ll know they stand behind their work. You’ll know the work will be completed, and you’ll be back on the road in no time. 

Don’t wait for head gasket failure

A head gasket is a small but crucial component that can make or break the health of your engine. Head gasket failure doesn’t have to happen. A simple maintenance routine is the best form of prevention. 

If you suspect a head gasket issue, don’t hesitate to consult one of our qualified mechanics for a thorough inspection and necessary repairs. Early detection and proactive maintenance are the keys to preserving your engine’s performance and longevity. 

Why Engines Smoke

by

Cars are a wonderful invention. They take you anywhere you want to go … until something goes wrong. 

Pay attention, and you might be able to stop issues in their tracks. It’s the best way to keep minor issues from turning into full-blown emergencies. 

Few things can cause your heart to race as much as engine smoke. What is it? What does it mean? 

Before you pull over and have your car towed, there are a few things to keep in mind. Let’s demystify this phenomenon and help you understand what it means for your trusty ride. 

Common Reasons a Car Engine May Be Smoking

You’re cruising down the road, enjoying the wind in your hair, and suddenly, you notice smoke billowing out from under your hood. Yikes! Before you panic and start imagining the worst, let’s take a look at some of the common culprits behind that smoky spectacle.

Leaking Head Gaskets

Think of head gaskets as the peacekeepers between your engine’s combustion chambers and coolant passages. When they spring a leak, things can get messy. The hot engine oil can mix with the coolant, resulting in white or bluish smoke.

Defective Coolant System

Engines work best at a specific temperature range, and your coolant system keeps things cool under the hood. If there’s a leak or a malfunction, your engine might overheat, causing steam and smoke to rise. Keep an eye on your temperature gauge.

Why Engines Smoke

Electrical Wires Burning

Modern cars are chock-full of wires that control everything from your lights to your engine. If these wires start to fray or short-circuit, they can emit smoke that’s often accompanied by a distinct burning odor. Safety first – if you see or smell this, pull over and call for help.

Worn Pistons

Pistons are like the heart of your engine – they move up and down to power your car. Over time, they can wear down, causing oil to leak into the combustion chamber. The result? You guessed it – smoke!

Faulty Fuel Valves

Your engine relies on a precise mixture of fuel and air to run smoothly. If your fuel valves are on the fritz, you might notice black smoke escaping from your tailpipe, signaling an overly rich fuel mixture.

What’s Causing the Smoke?

Now that we’ve covered the suspects, let’s dig deeper into what’s actually causing that smoke show.

Where is the Smoke Coming From?

The smoke isn’t just a magic trick – it’s coming from somewhere. Turn off your car and take a look around. Is it rising from the engine itself, the exhaust pipe, or maybe even the sides of the hood? This clue can help narrow down the source of the issue.

Be careful when opening up the hood. Smoke can indicate a problem. Lifting the hood can be dangerous if combined with steam or fire. Proceed with caution.  

What Color is the Smoke?

Believe it or not, the color of the smoke can provide some valuable insight into the problem. Let’s break it down:

What Black Smoke Indicates

If your exhaust pipe is puffing out thick, black smoke, your engine might be running too rich – meaning it’s burning more fuel than it should. This could be due to a faulty fuel injector, a clogged air filter, or even a problem with your engine’s sensors. It’s not just bad for the environment – it’s bad for your fuel economy, too!

What White Smoke Indicates

White smoke usually means one thing: coolant is getting into the combustion chamber. This might be due to a leaky head gasket or a cracked engine block. Don’t ignore this – excessive white smoke can lead to serious engine damage if left untreated.

What Gray Smoke Indicates

Gray smoke appearing as a thick cloud from your exhaust pipe is usually a sign that your car is burning oil. As oil escapes, it burns off as gray smoke from various parts of the engine. This liquid leaks into the combustion chamber, which can damage your catalytic converter and reduce fuel economy. 

What Blue Smoke Indicates

Blue smoke almost always indicates that your car’s engine is burning oil. As the liquid leaks into the combustion chamber, it burns alongside the fuel and creates a unique blue smoke. In addition, you might notice your car misfiring when you turn the key. Your car will shake and shimmy more than usual as it idles. Fixing it early will prevent further damage to your vehicle. 

When Does the Smoke Appear?

Is the smoke a constant companion on your drive, or does it only make an appearance during specific circumstances? Does it show up when you’re starting your engine, accelerating, or idling at a stoplight? These timing details can give your mechanic important clues to diagnose the issue.

Is Your Car Overheating?

Your car isn’t just a transportation machine – it’s a finely tuned orchestra of parts working in harmony. When one part goes rogue, like your coolant system failing to keep your engine’s temperature in check, your car might overheat. If your temperature gauge starts creeping into the red zone, pull over, turn off the engine, and let it cool down before continuing.

Now that you know why your car’s engine is smoking …

Remember, the key to keeping your car running well is observation and action. If you notice any unusual smoke, noises, or smells, don’t ignore it and hope it’ll magically disappear. Take a deep breath, pull over if needed, and call your trusted mechanic. It’s always better to address these issues sooner rather than later.

Understanding the Role of Engine Diagnostics in Car Repair

by

Imagine your world if there were no computers. 

You wouldn’t hold a smartphone in your hand, or use your tablet to watch your favorite podcast. You wouldn’t use your phone to adjust the furnace up a few degrees when you’re coming home from work. 

There would be no internet. You wouldn’t pay your bills at the touch of a button. Life would be simpler … and more complicated. 

Now think about your car. Since the mid-1990s, every gasoline car engine produced has come equipped with an onboard computer system capable of being accessed by diagnostics. When you take your vehicle into a repair shop, the mechanic will almost always plug a diagnostic tool into a port under the dashboard, and use the information collected to narrow down the problem. 

It can alert them to potential issues before they become bigger problems. It allows you to make minor repairs before they escalate into full-blown overhauls. 

What is a diagnostic test?

Have you ever wondered how mechanics pinpoint and fix issues with your car’s engine? The answer lies in the crucial role of engine diagnostics. In today’s modern vehicles, sophisticated computer systems continuously monitor various aspects of the engine’s performance. Through diagnostic tests, mechanics can effectively identify problems and provide accurate solutions.

A diagnostic test is a check-up for your car, performed using a specialized computer plugged into your vehicle’s onboard computer system, also known as the Engine Control Unit (ECU). This tool communicates with the ECU and retrieves valuable data about the engine’s performance, emissions, and various subsystems. It generates error codes that give information about any issues or malfunctions the car may be experiencing.

How does a diagnostic test work?

When the diagnostic tool establishes a connection with the ECU, it retrieves trouble codes, also known as Diagnostic Trouble Codes (DTCs). These codes serve as valuable clues that help mechanics identify specific problems.

Understanding the Role of Engine Diagnostics in Car Repair

Diagnostic tests are just the starting point of the repair process. They alert where a potential problem is located, but it’s not a cure-all that ends the repair process. Skilled mechanics must still rely on their expertise and perform additional testing protocols to diagnose the issue accurately.

What systems does the car’s computer monitor?

While it may vary slightly from car model to car model, the onboard computer system generally monitors the same systems. These include the engine control unit, transmission, exhaust, ignition system, emissions control system, airbag, and fuel injection system. 

The engine control unit, or ECU, is particularly important as it adjusts many critical factors affecting fuel consumption, idle speed, and emissions.

What will a diagnostics test tell you?

A comprehensive diagnostic test can provide valuable insights into the health of your vehicle. It can pinpoint specific problems, such as a malfunctioning sensor, a misfiring cylinder, a faulty oxygen sensor, or a failing catalytic converter.

Once the computer has run the scan, it will generate an error code, identifying any specific issues your car may be experiencing. However, these codes are not a definitive diagnosis – rather, they simply give the technician a starting point of what needs to be checked and repaired. 

A diagnostics test will provide valuable information about potential issues like a faulty oxygen sensor, damaged spark plugs, or a clogged fuel injector. It can also determine any other underlying problems contributing to the car’s issues.

Should you get a diagnostics test regularly?

While routine diagnostic tests are not necessary, they can be beneficial in maintaining your vehicle’s performance and catching potential problems early on. Regular diagnostic tests can help identify minor issues before they escalate into major and costly repairs.

Erring on the side of regular testing can help your vehicle stay in good working condition. Having the test done regularly can identify and repair potential issues before they cause significant or irreversible damage. 

We recommend you follow your vehicle manufacturer’s recommendation, typically every 30,000-50,000 miles. And indeed, any time you notice a change in performance or are concerned about something specific.

What’s the benefit of having a diagnostic test?

There are many benefits to having a diagnostic test. 

To start, it can give you peace of mind knowing that your car is running smoothly. If any underlying issues are detected, the test can identify and repair the problem before it causes further damage to the vehicle. 

Having periodic diagnostic tests can help save you money on potential future repairs by identifying issues when they’re small, rather than waiting for them to become more extensive and more expensive.

Timely repairs also help extend the lifespan of your vehicle and maintain its resale value. That’s a very good idea considering today’s vehicle price is now over $48,000.

How long will a diagnostic test take?

The duration of a diagnostic test varies depending on the complexity of the problem and the expertise of the mechanic. In some cases, a diagnostic test can be completed within an hour, while more intricate issues may require additional time for thorough inspection and testing.

It’s best to consult with your mechanic to get an estimate of the expected duration for your specific situation.

How do I know if I should schedule a diagnostic test?

If you notice anything out of the ordinary with your vehicle, it’s always a good idea to schedule a diagnostic test. 

If you experience a persistent check engine light, erratic engine performance, unusual noises, or a significant decrease in fuel efficiency, it’s crucial to have your vehicle checked. Additionally, if you notice any leaks, abnormal vibrations, or odd smells, these can also be indicators of underlying problems that require professional attention.

Schedule an inspection today

Engine diagnostics can significantly help car owners identify and resolve problems with their vehicles. They can provide significant information about your car’s onboard computer systems, giving qualified technicians a better understanding of what’s happening under the hood. 

The test only takes about an hour to complete, but it can identify and repair underlying issues before they become more challenging and more expensive in the long run. By getting tests performed regularly, you might be able to save yourself a lot of money and drive your car with confidence, knowing that it’s running smoothly.

Signs That Your Car Alternator May Be Failing

by

Sometimes car trouble hits you at the worst time. You’re late for a meeting, turn the key, and instead of the engine firing up, all you hear is: click, click. 

Is it a dead battery?

Or is it something else? 

Today’s average vehicle is made up of more than 10,000 parts. One piece works together with another to make your entire vehicle possible. But when one part goes bad, it can impact many others. 

That click, click might not be your battery. It might be the alternator instead. 

What does an alternator do?

Have you ever experienced being stranded on the side of the road with a dead battery and had no idea what went wrong? If you are nodding your head yes, then you might have experienced a failing alternator. 

Whether you are driving a brand-new or an old one, your alternator plays a pivotal role in keeping your car running smoothly. It’s responsible for keeping the battery charged while driving; if it fails, it can cause several problems for your vehicle. 

An alternator generates electricity to power your car’s electrical system and recharge the battery. It is connected to your car’s engine through belts and pulleys to create energy when the engine is running. The alternator sends power to the battery, which keeps the car running and powers the headlights, stereo, and other accessories.

The warning signs the alternator is failing

Without a properly functioning alternator, your car’s battery would quickly drain, leaving you stranded on the side of the road. Understanding the signs that your alternator may be failing can help you address the issue before it becomes a significant problem.

Signs That Your Car Alternator May Be Failing

Dashboard battery light

Have you ever noticed a dashboard warning light that looks like a battery? That’s the alternator warning light. If it comes on, it could mean your alternator is failing. If the alternator is not producing enough voltage, the battery will not be able to recharge, causing the battery light to come on. If you notice this light illuminated while driving, addressing the issue promptly is essential to avoid further complications.

Headlight trouble

If your headlights are dimming or flickering while driving, it could be a sign that your alternator is failing. The alternator provides power to the car’s electrical system, including the headlights, so if it’s not functioning correctly, the headlights may have trouble getting enough power to shine brightly.

Regular maintenance and prompt attention to warning signs can help you avoid unexpected breakdowns and costly repairs.

What is a Valvetrain and How Does it Work?

by

As drivers, we know what some car parts are for. The tires connect with the road. The steering wheel allows us to navigate turns and corners. Motor oil keeps the engine running smoothly. 

But other parts are a little more obscure. Like the valvetrain. It sounds important. But what exactly is a valvetrain, and how does it work?

What is a valvetrain?

In today’s modern cars, the valvetrain is integral to the engine’s functionality. It comprises various parts, such as valves, rocker arms, pushrods, camshafts, and lifters, that control the intake and exhaust of air and fuel in the engine. 

The valves open and close at specific intervals, allowing gasoline to enter the combustion chamber while expelling exhaust fumes. A well-maintained valvetrain ensures optimal engine performance, improving fuel efficiency, reducing emissions, and extending engine life. Therefore, it’s crucial to have a basic understanding of what a valvetrain is and how it contributes to your car’s overall performance.

How a valvetrain functions

To understand how a valvetrain functions, let’s begin with the basics of how an engine works. The engine’s pistons move up and down, creating pressure that drives a crankshaft, which powers the car’s motion. The valvetrain controls the air and fuel entering and leaving the combustion chamber, where the pistons move.

Each cylinder typically has two or more valves – an intake valve and an exhaust valve – both controlled by the valvetrain. The camshaft is a crucial part of the valvetrain and controls the timing of when the valves open and close. The camshaft rotates with the crankshaft, and its lobes push against the rocker arms attached to the valve stems, causing the valves to open and close.

The process of opening and closing valves is precisely timed to ensure that the right amount of fuel and air enters the combustion chamber while the correct amount of exhaust gasses are expelled, producing the desired power output.

Valvetrain components and what they do

A car is constructed from thousands of moving parts. The valvetrain is an intricate component with many parts coming together to keep your car operational. Parts include:

Camshaft

The camshaft is the heart of the valvetrain. It’s a rotating shaft with a series of cam lobes that control the opening and closing of the engine’s valves. As the camshaft rotates, the lobes push on the pushrods or rocker arms, causing them to move the valves up and down.

Pushrods

Pushrods are long, thin rods that connect the camshaft to the rocker arms. They transmit the motion of the cam lobe to the rocker arm, which then opens or closes the valve.

Rocker arms

Rocker arms are the pivoting levers that transfer the motion of the pushrod to the valve. They pivot on a shaft mounted on the cylinder head. The rocker arms come in various configurations, including stamped steel, cast aluminum, and roller tip designs.

What is a Valvetrain and How Does it Work?

Rocker shafts

Rocker shafts support the rocker arms and allow them to pivot smoothly. They are typically made of steel or aluminum and are mounted on the cylinder head.

Valve bridges

Valve bridges are small metal pieces that connect the intake and exhaust valves. They ensure that the valves open and close together, preventing interference between the valves.

Valves

The valves are the components that control the flow of air and fuel into the combustion chamber and the exhaust gasses out of the engine. There are typically two valves per cylinder, an intake valve, and an exhaust valve. The valves are opened and closed by the camshaft, pushrods, and rocker arms.

Valve springs

Valve springs are the coil springs that keep the valves closed when the engine is not running. They ensure that the valves close tightly against the valve seats, preventing any leakage of air or fuel.

Timing belt

The timing belt is a toothed belt that connects the camshaft to the crankshaft. It ensures that the camshaft rotates at the correct speed and in time with the crankshaft. The timing belt must be replaced periodically to prevent it from breaking and causing damage to the engine.

Belt tensioner

The belt tensioner is a component that maintains the proper tension on the timing belt. It ensures that the timing belt does not slip or jump teeth, which can cause the engine to run poorly or not at all.

Regular maintenance to keep the valvetrain at peak performance

One of the most important things you can do to keep your car’s valvetrain in peak performance is to change the oil regularly. Oil is the lifeblood of the valvetrain, and without proper lubrication, the valves can stick, causing damage to the engine. Additionally, the oil contains detergents and other additives that keep the valvetrain clean and prevent the buildup of carbon deposits.

Another essential maintenance task is to check the valve clearances regularly. Valve clearances, also known as valve lash, are the distance between the rocker arm and the valve stem when the valve is closed. Too much or too little clearance can lead to poor engine performance or damage. This is where it helps to have a mechanic you can rely on for regular maintenance. When they know a car well, they can help you maintain it over time. 

It’s also important to keep the air filter clean and replace it when necessary. A dirty air filter can reduce engine performance, causing the valves to work harder than they need to, wearing them out faster.

Is your car’s valvetrain in good working condition?

The valvetrain is a vital component of your car’s engine, and it’s essential to understand how it works to keep it well-maintained. Regular oil changes, checking valve clearances, and replacing air filters are just a few of the vital tasks required for proper valvetrain maintenance. 

By taking care of your car’s valvetrain, you can ensure optimal engine performance, prolong engine life, and save on fuel costs. So, the next time you’re behind the wheel, take a moment to appreciate the intricacies of your car’s valvetrain and give it the care it deserves.

Maintaining Your Car’s Refrigerant System For Optimal Performance

by

The temperatures are climbing all across the Front Range. 70. 80. 90 and more. It’s record-breaking heat, and your car isn’t happy. 

What’s worse, the temperature inside your car is even hotter. One study found that a car parked in the sun can reach 95 degrees or hotter within an hour. Dashboards can reach 157 degrees, and those seats can be a scorching 123 degrees. Ouch!

All of that can take a toll on your car’s air conditioner. It’s up to the refrigerant system to ensure its optimal performance. 

What do you know about refrigerant and how it helps maintain your car’s air conditioner? What you don’t know might impact you on the hottest days of the year. 

What is car refrigerant? 

Car refrigerant is a substance responsible for cooling the air in your vehicle’s air conditioning system. It circulates through a closed loop system, absorbing heat from the cabin and expelling it outside, creating a cooler environment inside. It plays a vital role in maintaining comfortable temperatures inside the car, especially during hot weather conditions.

Maintaining Your Car's Refrigerant System For Optimal Performance

Refrigerants are typically colorless, odorless, and tasteless, making it difficult to detect when running low or leaking. That may require analysis by a professional, but there are additional things you can do. 

Are there different types of refrigerant?

Refrigerants are not all the same. Over the years, different refrigerants have been used in car air conditioning systems. The most commonly used refrigerants are R-12 (dichlorodifluoromethane), R-134a (tetrafluoromethane), and the emerging R-1234yf (2,3,3,3-tetrafluoroprop-1-ene). R-12, also known as Freon, was widely used until the 1990s but was phased out due to its adverse effects on the ozone layer.

R-134a replaced R-12 as the standard automotive refrigerant and is still widely used in vehicles today. It is a more environmentally friendly option and has a lower ozone depletion potential. R-1234yf is a newer refrigerant that offers even lower global warming potential than R-134a, making it more eco-friendly. However, not all vehicles are compatible with R-1234yf due to differences in system design and requirements.

Do all types of refrigerant work in every car?

Refrigerants are not interchangeable; they do not work in every car. The type of refrigerant your vehicle requires depends on its make, model, and the system it is equipped with. Older vehicles designed for R-12 refrigerant cannot be retrofitted to use R-134a without significant modifications to the air conditioning system.

Vehicles designed for R-134a may not be compatible with R-1234yf without system updates. It is crucial to consult your car’s manufacturer or refer to the owner’s manual to determine the appropriate refrigerant type for your vehicle. Using the wrong refrigerant can damage the system, leading to costly repairs. If you have any questions, we can help. 

What causes refrigerants to be depleted?

Refrigerant depletion can occur due to various factors. 

The most common cause is a leak in the system. Over time, wear and tear can cause tiny holes or cracks in the refrigerant lines or components. 

Exposure to extreme heat while parked in the sun can also cause refrigerants to leak. That intense heat can take its toll on many parts and components. 

Don’t think a long, grueling winter isn’t hard on your AC unit. Moisture can build up in the system over time, causing damage to the compressor, evaporator, and hoses. 

Refrigerants can gradually escape through the tiny pores of rubber hoses, o-rings, and seals. Even a small leak can result in a significant loss of refrigerant over time, compromising the system’s performance and efficiency. Regular maintenance is crucial to detect and repair leaks promptly.

How do you maintain a car air conditioner?

Have you noticed that maintenance is critical to keeping your car running and all systems checked and working well? No matter what component you’re considering or what system you may have issues with, maintenance is key to returning it to good working condition and ensuring your car always runs well. 

To maintain your car’s air conditioner and ensure optimal performance, consider these tips:

Regular Inspections – Schedule periodic inspections of your vehicle’s air conditioning system by a qualified technician. They can check for leaks, test system pressures, and assess overall performance.

Leak Detection – If you notice a decline in cooling performance or an unusual hissing sound, it may indicate a refrigerant leak. Have it inspected and repaired as soon as possible to prevent further depletion.

Recharging – If your car’s air conditioning system is not cooling as effectively as before, it may be a sign that the refrigerant levels are low. Recharging the system with the appropriate refrigerant might be necessary. Recharging should be done by a professional who can accurately measure and add the correct amount of refrigerant to the system.

Cabin Air Filter Maintenance – The cabin air filter plays a vital role in maintaining the air quality inside your vehicle. A clogged or dirty air filter can restrict airflow, reducing the efficiency of the air conditioning system. Regularly inspect and replace the cabin air filter according to the manufacturer’s recommendations to ensure proper airflow and system performance.

Use the System Regularly – Running your car’s air conditioning system regularly, even during cooler months, helps maintain the system’s integrity. This practice prevents seals and hoses from drying out, reducing the likelihood of leaks. It also helps circulate the refrigerant, lubricating various components and keeping them in good working condition.

Keep the Condenser Clean – The condenser is located behind the grille at the front of your car. It is responsible for releasing heat from the refrigerant. Over time, debris such as leaves, dirt, and bugs can accumulate on the condenser fins, obstructing airflow and reducing cooling efficiency. Regularly clean the condenser using compressed air or a gentle stream of water to remove debris and ensure optimal airflow.

Protect from Excessive Heat – Prolonged exposure to extreme heat can damage the refrigerant and other components of your car’s air conditioning system. Whenever possible, park your vehicle in shaded areas or use sunshades to minimize the interior temperature. This practice reduces the strain on the system and helps maintain its performance and efficiency.

Seek Professional Help – While car owners can perform some maintenance tasks, seeking professional help for complex repairs or system diagnostics is essential. Certified technicians have the expertise and specialized equipment to effectively identify and resolve issues with your car’s refrigerant system.

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. 

How well is your timing belt working? If you have any questions, bring it in for an inspection. 

We’re here to help keep you driving, regardless of road conditions.

The Most Common Sensors Used In Your Car’s Engine

by

A car’s engine can be considered the central component that gives a vehicle the power to move. An internal combustion engine creates tiny, contained explosions to produce the energy necessary for movement. And while many refer to it as a car engine, it’s actually made up of several individual components all working together simultaneously. Engine sensors give it precision, ensuring the car engine works seamlessly as it ages. 

A car engine is designed around sealed, metal cylinders. Most vehicles today have between four and eight cylinders, which are made to open and close precisely as fuel and air enter with a spark for burning internally, exhausting the gasses produced outside. While there are many separate components, the essential include:

  • Engine block – the core of the engine 
  • Pistons – transfers energy created from combustion to the crankshaft to help propel the vehicle 
  • Crankshaft – the crankshaft turns the pistons up and down at engine speed
  • Camshaft – the camshaft regulates the timing of opening and closing of the valves, and the up and down motion of the crankshaft to control the movement of the pushrods and valves. 
  • Cylinder head –  is attached to the engine through cylinder bolts, sealed within the head gasket. It contains many of the internal parts of the engine and controls the passageways that allow airflow into the cylinders and exhaust back out. 
  • Timing belt/chain – the camshaft and crankshaft need precise timing to work properly. The timing belt/chain provides the action. 

While each of these components and systems are designed to work seamlessly together, modern day vehicles also use sensors for more precise movement. Modern car engines have up to 30 separate sensors to keep everything running properly, to control everything, and ensure optimal performance. 

The Most Common Sensors Used In Your Car’s Engine

Not every vehicle will come with the same type of sensors. Yet some are more universal, meaning you can find them across the board. The most common sensors in a car engine include:

Engine oil level sensor

One of the most common sensors is the engine oil level sensor. This sensor measures the oil levels inside the engine, ensuring it’s operating at safe capacity. If the oil drops below a certain level, the sensor will catch it and illuminate an oil level warning light on your dashboard. This sensor is often located at the bottom of the oil pan, which requires draining the engine oil in order to replace it. 

Engine oil pressure sensor

The engine oil pressure sensor is similar to the oil level sensor. It measures the oil pressure from the oil pump. It’s located at the engine block, often near the fuel filter.  These can often crack with age, which can cause a leak before it malfunctions. In most cases, people notice this when it illuminates on the dashboard. 

Coolant temperature sensor

A coolant temperature sensor monitors the coolant temperature, which is a great way to determine how efficient your engine’s overall temperature is. If an engine gets too hot, damage can occur. In newer cars, this coolant temperature monitors the inside temperature and can turn the engine off if the temperature gets too high.  

Mass airflow sensor

This sensor measures the amount of air flowing into the engine. It’s a computerized device that regulates the volume and density of air being moved throughout the system. It also ensures fuel is taken into the engine at the proper level. It’s located on the intake hose between the intake manifold and the air filter. 

Oxygen sensors

Oxygen sensors measure the air-fuel mixture from the exhaust, and determine how effective the catalytic converter is. One oxygen sensor measures air effectiveness before it enters the catalytic converter, and the other measures effectiveness after. If not enough emissions control is performed during the process, it alerts you via the check engine light on the dashboard. 

Knock sensors

Engine knock is a severe problem in combustion engines. It’s caused when the air/fuel mixture in the cylinder does not result in detonation and ignition from the spark plug. A knock sensor is there to ensure the engine doesn’t suffer from detonation, or the knocking process of not igniting correctly. A knock in the car engine can cause extensive damage to the internal parts. The knock sensor focuses this process and alerts you to a potential problem.

Crankshaft/camshaft position sensors

Engine timing relies on the crankshaft and camshaft executing in perfect tune. Position sensors time both to ensure they move together, always knowing where the other one is. If those positions are off even a fraction of a percent, you need to know as soon as possible. Having sensors on both the crankshaft and camshaft ensures both are in the proper position every time they move. 

Engine speed sensor

This sensor is attached to the crankshaft, and is responsible for monitoring the spinning motion. This controls fuel injection as well as timing for when the engine runs. This sensor ensures the car won’t stall or spin out of control while driving down the road. 

Manifold absolute pressure sensor

The manifold absolute pressure sensor measures the pressure in the manifold. It further supports the mass airflow sensor by measuring how much air makes it into the engine. This is critical to fuel-injection engines as it optimizes the air-fuel ratio for optimal performance. 

Exhaust temperature sensor

Depending on the make and model of your car, you may have one to four exhaust sensors designed to measure exhaust gas temperature before and after the particle filter. It controls engine conditions and effectively reduces emissions. 

Summary

While these aren’t all the sensors located throughout the engine compartment, it’s a list of just some of the sensors you’ll find in a vehicle. These are some of the more common sensors, and are likely to be the ones you’ll encounter problems with. 

While dashboard lights may be a bit annoying when they illuminate frequently, they are designed to alert you to problems as they arise, before they escalate into more significant problems. It’s the perfect way to fix an issue before it has the chance to destroy your car.
