Why Are My Tires Always Flat?

by

Have you ever noticed that on your busiest days, that’s when your car seems to take on a mind of its own? You know what I mean if you’ve ever run outside, late for a meeting, and found something wrong with your car.

While a dead battery might stop you in your tracks, it isn’t the only thing that can cause you to be late. One look at a flat tire will tell you you’re not going anywhere until it’s fixed.

And while a flat tire can hold you back until you change it, what happens when you come out repeatedly to a flat tire? What do you do when your tires are always flat? Why does it keep occurring back to back?

There could be several reasons for that. Let’s go over each of them to help you narrow down what’s going on with your vehicle.

Age

While a tire that goes flat once could be from a variety of things, if it keeps happening, there’s something else happening with your tire. When was the last time you replaced your tires?

Tires have a very important job on your vehicle. They connect you to the road, keeping you comfortable and safe as you drive along. They are continually being subjected to all kinds of things: rain, sleet, snow, ice, dirt, debris, potholes, heat … You get the picture. Every day brings on a new set of experiences. And your tires are designed to take it all in, and continue to protect your car.Why Are My Tires Always Flat?

Tires are made from a variety of materials, including rubber. These materials aren’t designed to last forever; they will eventually wear out.

There isn’t one set of guidelines to help you determine exactly when that is. However, tires do come with suggested guidelines you should follow. A high performance tire may wear down faster than one designed for all-weather performance. It also depends on what driving conditions it faces each day.

While you can start by determining how many miles you’ve put on this set of tires, you should also take a look at wear marks. Tire makers state that tires should officially be retired when the tread depth reaches 2/32 of an inch. If you’re kind to your tires, they can last for years. If you drive aggressively, it can shorten the curve immensely.

Dry rot

Age can cause your tires to degrade over time. But age isn’t the only thing that can go wrong. While age, in general, will impact the tread of the tire, dry rot affects your tire’s sidewall.

Dry rot isn’t created from bacteria as it does in a forest. Instead, dry rot on your tire is caused by age or exposure to certain conditions. They include extreme temperatures, UV damage, extensive periods of long term parking, and corrosive chemicals.

Think all of that describes Colorado living perfectly this year? Yep, us too.

The way to prevent dry rot is through regular maintenance. Checking your tires regularly can ensure they are inflated to proper levels, and that you don’t notice problems with the tire tread before you hop on the road and drive.

If you do park for extended periods of time, (like we’ve been doing here in the middle of a pandemic,) be sure you check your vehicle periodically to ensure it’s in good condition. That includes starting the car and running it from time to time to keep the systems working, and checking to ensure the tires are properly inflated.

Valve stem

If you’ve recently changed a flat tire, only to have it flatten again a few miles down the road, it’s time to take a look at the valve stem. The valve stem allows you to regulate tire pressure. It includes both the stem core and the valve cap. You use the stem core to add air into your tires, while the cap is used to seal out dirt and debris from entering.

Just like the tire itself, the valve stem can wear down over time. And as damage occurs, it can cause leaks. Inspect the valve stem. Do you notice any cracks? Does it appear to work when you fill your tires with air?

If you’re having problems regulating tire pressure, bring your vehicle in and we can perform a thorough check. It’s often a good idea to replace valve stems at the time you invest in new tires. This ensures the materials used are fresh and new, ready to perform for thousands of miles as you drive.

TPMS

Built inside the valve stem is a tiny sensor that warns your vehicle’s monitoring system of potential problems. TPMS – tire pressure monitoring system – is designed to track the tire pressure inside each tire, and provide a warning signal when it falls short of being within the manufacturer’s guidelines.

Because newer cars are all computerized, you can monitor any changes to your vehicle by merely keeping a watchful eye on your dashboard. While the actual dashboard signal may vary slightly from car to car, when you see a new icon illuminated, it’s time to find out what’s wrong. If a light blinks on and off, it might be a change in conditions. If it continues, it is a sign something is changing in the way your car operates. The best way to get to the root of the problem is to stop by and have us run a diagnostic test. It will help pinpoint where the problem lies, fix it, and get you back on the road again in no time.

Are you tired of changing tires? Are you tired of finding your car not ready to drive as you head out to a busy day?

Whether it’s due to age, dry rot, or there’s a problem with your tire pressure monitoring system, we can help you pinpoint the problem, and get you back on the road in no time.

Isn’t it nice to know there’s a local car care shop here waiting for you? You’ll receive honest answers every time you stop by. We’re here for you.

A Few “Key” Facts

by

You expect your key to turn in your vehicle’s ignition…but sometimes…it won’t, and that’s a problem.  Whether you’re trying to start your vehicle or trying to leave it, it’s a problem.

Here are a few “key” facts of what can cause this to happen.  One of the most common is that the steering column locking mechanism is stuck.  Locking steering columns are an anti-theft feature introduced in the 1970’s.  If yours is sticking, try moving the steering wheel a little from side to side as you turn the key;  sometimes this will cause it to release.

A key may also stick if the vehicle is in gear.  Most vehicles will only let you start in neutral or park.  If you have an automatic transmission vehicle, make sure it’s in park.  Move the shift lever through the gears and back into park to make sure.  If the key still doesn’t turn, you can try jiggling the shift lever as you turn the key.  Electrical and mechanical contacts sometimes don’t line up properly, and a little jiggle might nudge them into place.

Sometimes vehicles with alarms can cause a key to jam; some require the doors to either be closed or open before the key will move.  Other vehicles with newer electronic ignition systems won’t allow you to turn the key if the battery is dead.

Another possibility is something jammed in your lock cylinder.  The little pins and spring that figure out you are putting in the correct key can stick as well.  Your key may also be the culprit.  The ridges can wear down, or the shaft can get bent.  Oh, and speaking of the key, are you trying to use the right one?  Double check it.

If you have a key that resists turning and you’re able to get it unstuck, consider yourself warned.  It probably won’t “fix” itself, and it’s time to have your qualified technician dig a little deeper to track down the root of the problem.  You could be less “luc-key” the next time it happens.

Understanding Car Sensors, Why Your Car Has Them, And Keeping Them Well Maintained

by

In the early 1900s, thousands of different automobile companies existed across America, producing over 3,000 makes for consumers to choose from. Cars were simple by design, and had very few systems and parts when compared to today’s standards.

As driving became a mainstay, as roads weaved through every major city across the world and we began relying on vehicles like never before, safety became an issue.

So we modernized. Every system improved. Designs became sleek and sophisticated.

Technology entered the scene, and we found ways to improve a vehicle through a centralized computer system. The more parts a vehicle has, the more complex the systems became, the more of a need there was to help determine when something goes wrong.

That’s where car sensors come into the scene, helping owners understand when something goes wrong with their vehicle.

Understanding an internal combustion engine

An internal combustion engine needs three things to operate:

  • Air
  • Fuel
  • Spark

Going back in time, vehicles produced these three items with mechanical or electromechanical systems.

The carburetor was installed and used to control the mixing process, and meter how effective it was.

A mechanical distributor created and distributed spark delivery. A mechanical fuel pump would release fuel from the fuel tank and push it to the carburetor.

Understanding Car Sensors, Why Your Car Has Them, And Keeping Them Well MaintainedThis process was fairly straightforward, but very hands-on for maintenance. A vehicle would need a thorough tuneup every 30,000 miles or so to keep the engine running well.

As vehicles increased and became the norm in households all across the world, rules changed, and new operational mechanisms were developed. The 1970s brought on electronic spark delivery rather than relying on mechanical means. The 1980s changed the emissions system and what was acceptable for the environment.

As the systems grew in complexity, sensors were added to deliver information to an analog management system. The problem with analog systems is they had to be programmed and managed. They had their limits. They wouldn’t respond to things as they happened, and could still allow problems to escalate quickly.

That all changed as technology became more sophisticated. As carburetors were replaced with fuel injection, engines needed more information to work properly. And that’s where sensors became a bigger part of the way our current vehicles operate today.

Understanding car sensors

Cars in the 1980s and 1990s increased in functionality. Every aspect of the engine and drivetrain is now controlled by a central processor and a series of sensors. Currently, a vehicle has anywhere from 60 to 100 sensors built into the vehicle. However, that number will rise as cars continue to get smarter.

In general, car sensors can be broken down into separate categories, including:

  • Motion sensors
  • Pressure sensors
  • Position sensors
  • Temperature sensors

Each of these is considered to be sensory organs that send critical information back to the engine, and control how well your vehicle works. These sensors can detect even the smallest of changes, compensating for differences to ensure your vehicle stays operating well at all times.

How do car sensors work?

The purpose of a car sensor is pretty straightforward. They detect changes in the environment around them. If something changes, a trigger turns them on and sends the info to the appropriate place.

For example, a pressure sensor is designed to register pressure. When it goes beyond the designated limits, it sends the info to the central processor, which in turn triggers either an alarm or a light on the dashboard.

This notification is designed to give you advance warning of a potential problem. It’s intended to provide you with ample time to pull safely off the road, get to a service station to have the issue evaluated, and get the problem fixed before you drive your car once again.

Car sensors and what they do for your vehicle

The average car on the road today will have between 60 to 100 sensors. The best way to learn more about what your car offers is to spend some time with your owner’s manual.

Here are a few of the more critical sensors and what they do for your car.

Intake Air Temperature (IAT) Sensor

The intake air temperature sensor is an important part of keeping your engine in good working condition. It helps regulate the temperature of the air flow entering the engine. These temperature measurements are used as the engine balances the air-fuel mixture to properly operate the engine.

Cold air is denser than warm air, which means more fuel is needed to keep a proper balance for peak performance. The IAT sensor is mounted on the intake manifold in order to detect the temperature as the air flows in.

Oxygen Sensors

Oxygen sensors are one of the most common sensors on the vehicle today, having been on modern day cars for close to five decades. The oxygen sensor helps to keep the emissions in check by regulating the emission of the gases. While cars today have at least one oxygen sensor, many have up to four to help keep the car as efficient as possible.

Voltage Sensor

This is another common sensor that helps manage speed. It helps to ensure the car increases or decreases as required. It also helps control idling speed.

Tire Pressure Sensor

Tire pressure not only ensures you have a comfortable ride, but it also ensures you safely travel on the road without risk of an accident. Tire pressure sensors are located near the wheel and tire where it measures a tire’s air pressure. If it moves beyond the preset ratios, it alerts you to a potential problem.

Brake Fluid Sensor

The brake fluid sensor is located within a car’s braking system and helps detect brake fluid levels. Brake fluid operates under pressure, and any deviation to this pressure can impact brake performance. If fluid pressure ever drops, it alerts you through a dashboard light, giving you a chance to pull safely off the road and fix the problem quickly.

Car sensors – pay attention and stay safe

Like everything in our lives today, car sensors are designed to keep you well informed about how your vehicle is operating. Car sensors are an important part of the internal workings of your vehicle.

When any one of them is displayed, there is a reason for it. Don’t ignore them. Stop by and let us evaluate what’s wrong. The quicker you take action, the safer you’ll stay. And you’ll be able to fix the problem before it turns into something bigger.

Why Your Car May Fail The Emissions Test

by

How long have you called Denver home? If you were around in the 1970s or 1980s, you might remember the brown cloud. As we continued to industrialize our city, the population moved outward and began developing suburbia. That meant more driving for all of our daily needs.

The EPA adopted the Clean Air Act to establish standards on air pollution from both factories and vehicles. But even with this law, Denver’s air pollution was visibly noticeable, partially because the city sits in a bowl-like valley. With mountains on one side and the Platte River Valley on the other, a temperature inversion traps pollution inside this bowl, creating a “brown cloud” of unhealthy air.

While policies continue to work at keeping this brown cloud under control, it hasn’t gone away. Experts say that the brown cloud has been replaced by thick smog, with the EPA changing our overall rating recently from “moderate” to “serious.” In 2018, Denver logged 131 days of poor air quality. And that impacts everyone across the Front Range, especially those with compromised respiratory systems.

Years ago, Colorado set up a program to monitor gas emissions from vehicles. Its goal was to keep the worst Why Your Car May Fail The Emissions Testpolluters off of the roads. Several counties require an emissions test to register a vehicle, including:

  • Boulder
  • Broomfield
  • Denver
  • Douglas
  • Jefferson
  • Portions of Adams
  • Portions of Arapahoe
  • Portion of Larimer
  • Portions of Weld

There are exceptions to this rule. If you aren’t sure if this rule applies to you, check with the Colorado Air Care Testing Facility near you to determine if your car needs testing, and how often you should take it in.

What an emissions test checks for

An emissions test is designed to ensure that a vehicle isn’t producing unacceptable levels of toxic gases. Tests are designed to measure the amount of emissions coming from a car’s engine. It’s a simple test that checks the pollutants being emitted from the tailpipe and being released into the air supply.  It measures:

  • Nitrogen oxide (NOx)
  • Carbon monoxide (CO)
  • Particulate matter (PM)
  • Non-methane organic gases (NMOG)
  • Formaldehyde (HCHO)

If your car passes, you can register your vehicle and drive it on the roads.

But what if your emissions test fails?

Here are the most common reasons a car will fail an emissions test.

Your car needs an oil change. An oil change is considered to be regular maintenance. It’s something that you should perform regularly, whether you drive regularly or not. Clean oil has fewer hydrocarbons in it, and helps keep your engine cleaner. A clean engine means cleaner emissions output. Check with your vehicle’s manufacturer, or refer to your owner’s manual to determine how often your oil should be replaced. Remember, this is based on time and miles driven. Even if you work from home and your car sits idle most days, it doesn’t mean your car doesn’t need fresh oil on a regular basis.

Your car has a rich air-fuel mixture. This is often caused by a malfunctioning injector or a faulty oxygen sensor. Check and replace both of these items before checking the emissions once again; this fixes the problem in a lot of cases. If the system continues dumping too much gas into the system, it will burn out the catalytic converter. Bringing it into our shop for a thorough checkup can find this and fix it if it’s the problem.

Your spark plugs are worn. When spark plugs wear down, they produce incomplete combustion. The spark plug creates electricity that ignites the air-fuel mixture inside the engine. The spark plugs create the motion inside the piston, and continue to provide power to keep your vehicle moving. When this process is incomplete, it can impact how much your car is emitting. Changing your spark plugs may be all that is needed to get your car back on the road.

Your car’s gas cap is leaking. This is a simple issue you can fix yourself. First, inspect your gas cap to see if it’s properly sealed. Tighten it if necessary. If you notice a leak, replace the gas cap and test your vehicle’s emissions again.

Your car’s air filter is dirty. When a vehicle’s air filter clogs, it can increase the levels of hydrocarbons being emitted from your car’s engine. Most manufacturers suggest replacing your car’s air filter at least once a year. If you don’t remember when you last had it changed, consider replacing it and trying the emissions test again. This should be a part of your regular maintenance plan to ensure your vehicle is in the best condition possible.

Your car’s evaporative emission control system (EVAP) is defective. When a vehicle’s EVAP system isn’t working correctly, gas vapors will move from the gas tank and add to the pollution levels in the atmosphere. This is often caused by a leak in the hoses or vents, causing the EVAP system to work improperly. While this can be difficult to track, a thorough diagnostics test can often reveal where the problem lies.

Your car’s check engine light is defective. While every light on your dashboard is important, the check engine light is one you should never ignore. It can signal many different problems with the way your engine operates. Occasionally, the check engine light itself may malfunction, and be the cause of why your car is failing the emissions test.

The best way to proceed is with proper maintenance and an inspection by a professional mechanic

While a failed emissions test isn’t a sign your car has major systems problems, it is a warning of an issue that needs solving.

While regular maintenance can keep your vehicle in top driving condition, it’s an ongoing process.

By stopping by regularly, we can ensure your vehicle is in good condition, and will give you peace of mind, knowing your car will be reliable no matter where your travels take you.

Auto Repair Inspection For Before You Buy A New Used Car

by

One of the good reasons for having an auto mechanic on your side is they can help you through all kinds of situations. It’s nice knowing you’ll get an honest answer to all of your vehicle questions.

While that may be important if you notice a squeak when you apply the brakes, or hear a noise as you drive through a turn, it’s equally important when you consider buying a used car.

Used cars have been through a lot as they travel down the road. Yes, it might look good from the outside, the paint might be in good condition, the interior might be spotless. But how do you know if the internal workings of the car make it a good used car?

That’s why knowing a reputable auto mechanic can help you out.

If you’re looking at buying a used car, it’s important to do your homework before you start the search.

According to AARP, the average mileage per year is between 12,000 and 15,000 miles. That means for a five-year-old vehicle, having between 60,000 and 70,000 miles on the odometer isn’t out of the ordinary.

The Bureau of Transportation states that today’s vehicles on the road average just over 11 years. The standard vehicle being built today can fully be expected to continue running through 200,000 miles and more, with some inching their way towards 300,000.

Auto Repair Inspection For Before You Buy A New Used CarThere are a lot of reasons to keep your vehicle that long. The obvious is to save money on the price of purchasing a new vehicle.

That also makes it worth the time to buy a vehicle only a few years old. You can easily expect a vehicle to give you years of quality life, even if you purchase one a few years old.

That’s one of the biggest reasons it’s worth your time to ensure you’re buying a quality used car.

Inspections aren’t required when you buy a used car

There aren’t specific laws that give you the authority to have an inspection before you purchased a used vehicle. However, the Federal Trade Commission does advise people on specific steps people should take before you buy a used car.

Some are obvious:

  • Test drive the car on varied road conditions – on hills, highways, and stop and go traffic
  • Determine the value before you negotiate the price

Still others are great advice:

  • Ask for the car’s maintenance records from the owner
  • Get an independent review of the vehicle’s history. You can check with the Department of Justice’s National Motor Vehicle Title Information System to find out information about the vehicle’s title, which can help you determine if the car has been in an accident, flood damage, and other possible risk factors.

And finally, they recommend considering hiring a mechanic to inspect the car.

If the seller is reputable and is sure of the condition of the car, they will be happy to allow an inspection to take place. If, however, they are hiding something, an argument about this process should be your warning sign.

What will a good mechanic check on a vehicle inspection?

There are certain things you can do as a potential used car buyer. You can perform a road test to see how the car drives. You can check the odometer for mileage. You can check the headlights and taillights to ensure everything is working. You can use visual cues to help determine how well the owner took care of the car.

But a good mechanic will go deeper into how the car operates. They look at:

Tire inspection – this is a good indicator for how well the car is maintained. They look for uneven wear at the inside or outside edges. They look for jagged edges in the tread. They look for uneven cupped patterns that may indicate suspension problems.

Test drive – a good mechanic is trained to pick up small noises that occur as you drive around. They take it through a series of tests, including highway driving, up and down hills, and in stop and go traffic, to see how it handles. Clunks, rattles, squeaks, and clicking noises can all be indicators of potential problems. If they note a sound, they can check it more thoroughly back in the shop.

Stop test – while it’s not something any of us should do on a regular basis, occasionally, you might have to slam on the brakes to come to a stop. The way your car brakes can tell you a lot. It’s also a good test before you buy a used car. In a safe area, doing a hard stop from 40 miles per hour will show how the braking system works. Does it pull to one side? Does it lock up? Do the brakes pulsate? A vehicle with all of its systems working correctly will stop in a straight line.

Fluid test – first and foremost, motor oil should be honey-colored and translucent. If it’s dark or has a sour smell, it could be a sign of a problem, and at the very least alert you to the fact that the previous owner didn’t change out the motor oil on a regular basis. It’s not the only fluid that should be checked. A mechanic will check for leaks, and ensure all other fluids are in good condition.

Of course, depending on where you go, mechanics can do a variety of other things to, depending on the age, make, and model of your car. Hooking it up to a diagnostics test can reveal hidden problems. Putting it up on a rack to look at the undercarriage, and giving the body a thorough evaluation can point out potential issues.

If you’re in the market for a good used vehicle, don’t overlook what a thorough inspection can do for you. It can be the difference between buying a lemon and investing in a quality car that will give you years of reliability.

Should You Invest In Better Brake Pads?

by

We’ve all heard the phrase, “you get what you pay for.” But does it apply to every situation? With something as sophisticated as your car’s brake system, is there a big difference between the different types of brake pads on the market?

To answer that question, let’s start with how the brake system works.

Understanding today’s modern brake system

Your vehicle is designed with four wheels, each with a brake attached to help slow it down. Car brakes may be disc or drum, depending on the way it was designed.

The front brakes provide you with more braking power. Think about the force for a moment, when you press down on the brake pedal to slow for a stoplight. The force of the vehicle moves forward, putting more pressure on the front of the car.

Disc brakes, in general, are better at stopping. You’ll find many cars today have disc brakes on the front, and drum brakes on the rear. All disc braking systems are found on some expensive or performance-driven cars, while all drum brakes may be found on older models, manufactured before disc brakes grew in popularity.

When you push down on the brake pedal, a piston moves inside the master cylinder. This allows fluid to move through pipes to slave cylinders located at each wheel. This transfer of fluid depresses pistons at each brake, forcing the brakes into action and the vehicle to slow.

This fluid is designed to distribute evenly throughout the system. This is what keeps your brake system working at optimal capacity.

You can also see the importance of having this process work correctly. An error or shutdown could have devastating impacts. Therefore, most modern cars have twin hydraulic circuits with two master cylinders, in case one of them no longer words. These twin systems can either each take a section – the front or back – or work in conjunction with each other to produce reliable force.

Why better brake pads can increase your safety

Should You Invest In Better Brake Pads?With a disc brake system, a disc turns the wheel. The disc is straddled by a brake caliper, which is controlled by pistons operating from the master cylinder. These pistons press against brake pads that case friction and stop the vehicle. These pads are shaped to cover a significant portion of the rotor, to ensure it properly stops the car.

This entire system is designed to apply pressure “just enough” to put the brakes into action. There aren’t springs to control it; instead, it all works via hydraulics, where pressure forces the pads against the rotor when the brake pedal is pressed, and released when it’s not. The two are close together by design, so only a small amount of movement is needed to put the brake system in action.

You can imagine the force needed to bring thousands of pounds of metal to a stop when it’s traveling down the road at 40, 50, or even 60 miles per hour. Brake pads endure a lot of force as you use the brakes again and again as you drive around.

When you purchase brake pads, rest assured no matter which you choose, they will get the job done. However, it’s also important to note that there are no federal safety standards for aftermarket brake pads.

Federal standards issued by the National Highway Traffic and Safety Administration set rules about new car standards, but do not establish regulations for aftermarket replacement brakes. The standards set for new vehicles ensure safe driving by requiring a car to stop within a certain distance, but the same rules don’t apply for replacement parts.

That’s why it’s important to know where your parts come from, and ensure you are using a trustworthy source for brake replacement.

In general, there are two types of brake pads on the market today: ceramic and semi-metallic brake pads.

Ceramic brake pads were first introduced back in the 1980s and have gained in popularity. Ceramic brake pads are composed of a material you’ll find in your ceramic cookware, only a much denser fabric. Copper fibers are weaved through to help conduct and disperse heat. Ceramic brake pads are designed to be a softer material that won’t wear against the rotor as fast as other materials. That means they have a longer service life, will have less noise, and create less brake dust than its counterparts.

Semi-metallic brake pads, on the other hand, offer better performance. That’s because their friction quality is controlled by a variety of metals, including iron, steel, and alloys, all bound together by a small amount of graphite lubricant. You’ll find budget semi-metallic brake pads with a composition that is roughly 30 percent metal, but the best will contain higher ratios, as much as 60 percent or more. These brakes have great stopping power, durability, and dissipate heat better than other types of pads. But there is a trade-off – they can be a bit noisy, and will create more brake dust than ceramic brakes.

What’s the difference? What makes one brake pad better than another?

Ultimately, it comes down to the braking power. The major difference between the different pad materials will be on the friction layer, or the part that connects with the rotor. This is the part that causes your car to slow and stop.

Both economy and premium brakes will get the job done. Safety requirements do require all brake pads sold on the market to meet certain regulations. However, premium brake pads will offer better performance, and will always outperform lower quality brands. Premium brake pads have an increased stopping power and decreased brake fade. That means brake performance will remain consistent no matter how much pressure they are put under. That can be a big deal if you drive up and down the mountains, especially with a big payload.

Premium brake pads also use higher quality materials, which typically will give you longer wear factors. They are designed for longer service life and will wear more evenly overall. Better materials also mean less chance for particles to wear off. Brake dust can cause uneven wear on your brake pads. It can also cause squealing as the brake dust wears away.

When was the last time you replaced your brake pads? 

Why You Change Your Transmission Fluid

by

It’s very easy to forget about servicing your transmission because it doesn’t need it very often, but when you change your transmission fluid it keeps your vehicle running smoothly and helps you avoid costly repairs down the road.  Your transmission undergoes a lot of stress.  The grit you see in used fluid is actually bits of clutch material.  This grit flowing through your transmission under pressure eats away at seals and gaskets which can lead to leaks.  The transmission operates at very high temperatures – much higher than engine temperatures.  Those high temperatures eventually cause the transmission fluid to start to break down and loose efficiency.  At best, your transmission won’t operate smoothly.  At worst, it could lead to very costly damage.  When you change your transmission fluid and it’s running properly, it transfers more power from your engine to the drive wheels and improves fuel economy.  That’s why manufacturers have recommended changing your transmission fluid at regular intervals.  Your owner’s manual has a schedule for transmission service and, of course, your Express Car Care service adviser can tell you what the manufacturer recommends.  At Express Car Care, we are able to perform a transmission service while you wait and the cost is usually quite reasonable.  When you think about how much a major transmission repair can cost, the cost to change your transmission fluid with our transmission service is downright cheap.  Come on in or give us a call and let us know what we can do to help you keep your car on the road.

All Signs Point To A Bad Alternator

by

Today’s modern vehicle is designed with thousands of parts working together to keep you on the road. While most of us know how a few of the systems work, other parts aren’t as clear.

Tires connect to the road, keeping you comfortable and safe. A battery keeps the car running. Or does it?

A car battery is used to provide electricity to the electric starter motor designed to turn your vehicle on. But once the car is running, the power moves to the alternator, which generates energy to continually feed the electrical system while in operation.

Think of your alternator as a generator. When your vehicle is started, the engine spins wheels underneath the hood. One of those wheels is connected to the alternator, which generates energy. That energy is what keeps your electrical system running.

How do you know where the problem is with your vehicle? What are the signs of a bad alternator?

Bright or dim lights

All Signs Point To A Bad AlternatorWhen your electrical system isn’t getting enough current, it impacts the various accessories on your vehicle, including your lights. When you drive in the dark, is it harder to see? Does it appear your lights have dimmed? Or do they seem to be shining too brightly?

When an alternator begins to fail, it provides inconsistent voltage to the various systems in your vehicle. And that often translates to either underperforming or overperforming equipment. It’s usually most noticeable in headlights that appear either too dim or too bright. You may also experience flickering lights as you drive through the night.

Trouble starting

When you turn the key, you expect your vehicle to jump into action. If your alternator is starting to fail, that might not occur with regularity. You may have to turn the key a time or two, trying to get the engine to stay running.

For most car owners, the thought immediately turns to the battery. And while it might be the case, it’s important to consider all of the possibilities. How old is your battery? When was the last time you changed it out? Watch for other clues to determine where the problem lies.

Stalling

You may find the reverse happening too. As you drive your vehicle, stopping for lights and stop signs, you may find your car frequently stalls out.

If this happens regularly, it’s not your battery failing. Instead, it’s a sign that your vehicle’s spark plugs aren’t retaining enough power to keep your car operational. Without the flow of energy, your car simply can’t keep going.

Dead battery

There may be other times where you try to start your car and the battery is dead. You turn the key and nothing happens.

It could be just that – a dead battery. Maybe you left your light on overnight, and it drained the power from the battery. But if you’ve noticed other signs of potential problems, you might also determine it’s a sign your alternator is failing.

A bad alternator won’t charge the battery while the engine is running. That means the energy dissipates from the system quicker, preventing it from turning over when you go to start it.

A great way to test to see if it’s your battery or the alternator is to jumpstart the car. If it stays running, it’s your battery. If it dies shortly after the jump, it might be that your alternator isn’t supplying enough power to the battery.

Accessory problems

The electrical system supplies energy to many different parts of your car. It includes your power windows, your radio, your seat warmers, your windshield wipers and more. If you notice your windows take longer to move into place, it might be a sign the electrical system isn’t working at its best.

Thanks to today’s technology, there’s a hierarchy to where energy flows in the event of a problem. Your car is programmed to keep your car running, keeping you safe from potential problems. It’s programmed to stop supplying energy to things lower on the list – your radio or seat warmers – before turning off more vital systems – your headlights.

That’s why it’s important to pay attention to all warning signs as they occur. If you notice your radio fading in and out, there might be a reason for that.

If it keeps occurring and you notice other problems, it’s time to get your vehicle tested and the problem solved.

Noises

Cars make a variety of noises. From the moment you drove it off the lot, you’ve become attuned to the noises your car makes. Pay attention to any noises that change over time.

Do you hear a growling sound? Or a whining noise coming from under the hood? Whether something changes, gets louder, or worsens over time, your best course of action is to have a mechanic check things out.

Odor

Another warning sign that may occur is a strange odor coming from underneath the hood. A burning rubber smell could indicate parts are starting to wear out. The alternator’s drive belt is under constant tension and pressure. And because it’s near the engine, it can easily emit a burning smell as it comes closer to the engine compartment.

A burning odor can also occur as your alternator ages. If it has frayed or the wires are damaged, it’ll be reminiscent of an electrical fire.

Battery warning light

Your vehicle’s monitoring system is designed to warn you of any potential problems. When the battery warning light pops up on the dashboard, it can be from various problems. Many drivers assume it’s a problem with the battery. However, it’s also designed to illuminate any issues with the electrical system, including the alternator.

The alternator is designed to work at a specific voltage. When it falls outside of the recommended levels – usually 13 to 14.5 volts – it’s a sign that it’s failing. And when that happens, the battery dashboard light will illuminate.

Depending on how the electrical load is impacting your car, it can also cause the battery light to flicker on and off. If power isn’t getting to your headlight or wipers, for example, the battery may flicker as it attempts to do its job. If you notice this frequently, it’s worth further investigation.

Whether you’ve just started noticing a problem with your electrical system, or your car simply won’t start, we’re here to help you with all of your vehicle’s issues.

Key Reasons Why Cars Last Longer Than Ever Before

by

According to the Environmental Protection Agency, the average car is driven about 15,000 miles per year. The New York Times found that fifty to sixty years ago, the average expected life of a vehicle was around 100,000 miles. Today, because of better technology, tighter tolerances, and better anti-corrosion coatings, the average life is closer to 200,000.

Cars are lasting longer than ever before. While that may be good for you as the car owner, it can compromise the overall driving experience if it isn’t well maintained. The average age of cars and light trucks on the road has reached peak levels to 11.8 years in 2019. It’s predicted to be more than 84 million vehicles on the road at least 16 years old by 2023. That poses significant problems, especially when car manufacturers 16 years ago weren’t thinking about that kind of longevity.

Why are coats lasting longer?

And equally important, what can you do to ensure your vehicle will last you for many years to come?

Improving the way a vehicle is assembled

Key Reasons Why Cars Last Longer Than Ever BeforeThe way cars are produced has changed a lot over the years. To say they’ve gone through a massive overhaul in the last century would be an understatement.

The first cars were powered by steam at the turn of the century. They didn’t have windshields, doors, or turn signals. Safety features – they weren’t in existence.

Mass production is what brought the first inkling of what we have with our vehicles today. Slowly, cars became safer, more durable, with improved systems and functions to create a better driving experience.

Laws like the 1966 National Traffic and Motor Safety Act worked on improving driving conditions. It included traffic safety programs, driver education and licensing, inspections, highway design, and traffic law enforcement.

The National Highway Traffic Safety Administration began testing and rating vehicles for collision protection in 1978. That made manufacturers work harder at creating vehicles that would protect passengers.

And it all starts at the assembly line, with the way today’s modern vehicles are put together. What used to be left to humans, which varied from person to person, is now a precise task as machines and robotics handle every detail.

Emphasis is placed on making every part better, stronger, lighter, and more efficient. To improve fuel economy, for example, required designers to come up with ways to make body parts more efficient. They had to be thinner, lighter, and made of better materials so they wouldn’t rust or corrode.

All of this is because regulations keep getting better. And that isn’t going to stop. We now demand it in every car we purchase, knowing it’ll give us years of service.

Engine efficiency

Old engines made a vehicle operate, but they weren’t very efficient. That’s changed as laws and regulations required it so.

Old carburetors would drip fuel into the engine, and because there wasn’t a lot of control, that extra fuel would wash away, corroding parts as a part of the process. Unburned fuel would dilute the oil, wear out rubber, and cause the engine to be anything but efficient.

Now, modern fuel and oil have been modernized to the current status where they are beneficial at helping vehicles thrive. You no longer have engines that die from corrosion and buildup. Fuel injection makes every system a precise course of action. It controls fluids in such a way that they go where needed, in the right amounts, at the right time. A cleaner combustion process means a better engine that lasts longer, and saves on fuel and oil in the process.

Motor oil from just a few decades ago was simple at best. But as mechanics and engineers learned more about the process, they refined the fluids used in today’s engines. Synthetic oils are designed to work no matter what the temperature is outside, from freezing cold to sweltering heat. This isn’t the motor oil your parents used.

Thanks to technology, you can go farther between servicing, and expect parts to last for tens of thousands of miles. Spark plugs, for example, now last 100,000 miles or more.

It’s no longer about guessing when you’re vehicle is in need of repair. Today’s vehicles will tell you what it needs, when it needs it.

Better electronics

Imagine a vehicle that can tell you what it needs. Gauges alert you when you’re running low on fuel. Lights warn you of potential problems. Voice commands give you diagnostics, and offer refinement to improve the driving experience.

Of course, this isn’t sci-fi; this is reality. All you have to do is sit in a new car and you’ll find technology a big part of how it operates.

With on-board computer sensors and monitors, every system, every piece is watched closely to ensure it’s operating the way it should. When something moves outside of the established limits, a sensor is alerted, and it warns you via a dashboard light. They are finely tuned to maximize part life, give you advanced warning to bring your car in for servicing, and lessen the likelihood of being stranded because of a part that no longer works.

Establishing a car maintenance program you can live by

If you choose to keep your vehicle for years, it’s important to service your car regularly to maintain each of the systems at optimal performance. The average car built today includes over 30,000 parts. Each of those parts are attached and combined to work together. If one part is bad, it has the ability to impact every other part in some manner.

A reputable auto mechanic isn’t just there to service your vehicle when you have problems with your car. They are also there to be a part of the team that keeps it operating correctly for as long as you own it.

If you’re looking for a partner to keep your car operating in great condition, stop by today and give us a try. From regular oil changes to overhauling complete systems, we can help your car stay safe and on the road for years to come.

Driving on Technology

Driving on TechnologyThink of how much technology has changed vehicles in the last several years.  And there’s a lot more coming.

Many of you will remember when drivers were the ones who had complete control of several driving functions:  steering, braking and skid and accident prevention, just to name a few.  Thanks to driving technology, now computers and high-tech systems in the vehicle assist with many of these skills.  Anti-lock brakes help the driver stop while avoiding uncontrolled skids, traction control helps reduce slippage, and stability control can minimize the chances of losing control.

Backup cameras let drivers see what’s directly behind them which they never could see before.  Sensors warn drivers if a vehicle is crossing in front or behind them.  Even more sensors and fish-eye cameras alert drivers when they’re getting too close to something.  And those are just a few samples of the new driving technology advances.

The quest for self-driving vehicles has produced features that are already making their way into today’s cars, trucks, and SUV’s.  Electric and hybrid vehicles are introducing break-out driving technologies.  For example, a new braking technology allows the driver to let up on the accelerator, and instead of the car coasting for a while or the driver having to apply the brakes, the vehicle will slow down using regenerative braking without the driver even touching the brake pedal.  This regenerative braking system recharges the batteries.  Another system helps steer the car to keep it in the center of the lane using cameras and radar to keep track of the lane markers.

Most of these driving technologies aim at improving safety and efficiency, in much of the same way as all the other systems installed in the vehicle you currently own.  But whether you’re driving on new technology or not, it’s always important to keep them maintained so they’re working properly.  At Express Car Care we invest in training and diagnostic tools and equipment to keep your high-tech systems up to date as we all move forward to the vehicles of the future.
