Why is My Check Engine Light On?

You are driving your car down the freeway, and everything seems to be fine. Then suddenly the Check Engine Light illuminates on the dashboard. When this issue occurs, it is important that you address this problem in a timely manner.

In this blog, we will take a look at what to do when your Check Engine Light comes on, some possible reasons for it, and most importantly, how to get the problem resolved.

What is the Check Engine Light?

Today’s vehicles are extremely intricate machines, with many onboard computers controlling all the vehicle’s complex operations.

When the Check Engine Light becomes illuminated it is a warning to the driver that the car’s onboard computers have detected a problem that a system in the vehicle is not performing as it should.

Your vehicle will also tell you the severity of the situation by illuminating the Check Engine Light in several different ways. A solid yellow light means that the issue at hand is not immediately urgent but should be addressed.

A flashing light is an indication that something is seriously wrong and requires immediate attention.

Anytime your Check Engine Light comes on it is very important to take your car to a qualified repair shop to diagnose the issue.

Top Reasons That Check Engine Lights Appear

Engine Issues

Various engine problems can trigger the Check Engine Light to come on. Whether it be low oil pressure, overheating, or drivability issues, the light is a warning that something is going on that should not be happening.

Transmission Problems

Your car’s transmission plays a critical role in its operation, as it transfers engine power to the wheels, so the vehicle can move. Some transmission issues are mechanical in nature, and others are electronic or computer related. Transmission problems may cause the Check Engine light to illuminate.

Emission System

Today’s modern cars are equipped with sophisticated emissions systems that are designed to minimize the amount of pollution a vehicle produces while in operation.

There are many sensors and other components that make up a car’s emission system. If any component stops performing as it should, the Check Engine Light will appear.

Overheating

Engines and transmissions produce a tremendous amount of heat as they drive down the road.

A car’s cooling system is designed to keep the vehicle’s operating temperature within the proper range. When this system develops an overheating problem, serious damage to the engine can result.

How Do You Resolve a Check Engine Light Problem?

Just as cars have many sophisticated on board computers today, modern repair shops invest in complex diagnostic equipment that is used to determine what is wrong with a vehicle, and the best strategy to fix it.

Highly trained technicians connect to a car’s computer system by using diagnostic equipment at the repair shop. Based on a wide variety of trouble codes and performance measurements, a technician can interpret the nature of a vehicle’s issue and decide how to properly repair it.

Once the proper repairs have been made, the technician can “clear” the Check Engine light and turn it off. Then the technician will take a test drive and ensure all systems are operating properly.

Why is My Car Leaking Coolant?

One of the most important components of your car’s engine is its cooling system, as it is responsible for preventing the motor from overheating while driving. If you happen to notice, a bright green or orange fluid on the ground under your car, you could have a coolant leak and should get the issue addressed right away.

Let’s look at 5 reasons your car might be leaking coolant or what is known as anti-freeze.

Leak in the Radiator or Hoses

A car’s radiator is usually located in the front of the engine compartment, behind the grill. It is responsible for taking hot coolant from the engine and reducing its temperature. The coolant is then returned to the engine. This process is repeated in a continuous cycle.

If your radiator springs a leak, coolant will pour out onto the ground. This can be hazardous, as a leaking radiator will not be able to cool anti-freeze properly. In addition, the car’s coolant supply will eventually leak out, possibly causing severe engine damage. Take your car to a qualified technician to see if your radiator or one of its hoses is leaking.

Faulty Radiator Cap

Sometimes a leak can come from the radiator cap itself. Because the cap is constantly under extreme pressure, its seal can wear out, causing a fluid leak. A qualified repair shop can test your radiator cap for proper performance.

Water Pump Leak

Your car’s water pump is responsible for circulating coolant around the engine and to the radiator. Leakage is one of the first signs of a faulty water pump. A failing water pump can cause a vehicle to lose a great quantity of coolant and eventually overheat. Have an auto repair shop inspect your water pump for leaks and to determine if it is functioning properly.

Blown Head Gasket

A failed head gasket can cause serious damage to an engine, even to the point of seizure. The head of the engine is where the fuel, ignition, exhaust, and intake systems all come together to perform their various functions.

A car with a blown head gasket needs to be turned off right away, to avoid catastrophic damage from occurring. If you suspect that this has happened to your vehicle, consult with a qualified repair person immediately.

Expansion Tank Crack

When a car warms up to normal operating temperature, pressure builds up in the radiator which necessitates some of its coolant to be transferred to an expansion tank.

Over time, this plastic tank can crack, causing leaks. Have a trusted auto shop inspect your radiator system and its expansion tank. If you see a coolant leak coming from somewhere other than the radiator, have a technician check the expansion tank.

Why Your Car’s Engine Is Making a Rattling Noise

Are you hearing a rattling or pinging sound from your car? Is the noise coming from the engine area? An engine rattling noise can be a sign that something is wrong, and should be addressed as soon as possible. Let’s take a look at some possible reasons why your car’s engine is making unusual sounds.

A Rattling Noise from the Engine When Accelerating

Noises coming from the engine when you are pushing on the gas could be caused by a loose or weak timing belt, chain tensioner, cracked flywheel, or a broken flexplate.

These issues will only get worse over time, not better. It is important to bring your car into the repair shop as soon as possible.

Noises Coming from the Engine When Idling

A common problem that may be causing a rattling noise while idling involves the engine’s hydraulic valve lifters. This part of your car is responsible for opening and closing the engine’s intake and exhaust valves.

When a lifter is not working properly, a loud ticking sound can usually be heard under the hood.

Another issue that could be causing a rattling noise at idle is piston slap. If one or more of your pistons no longer fit properly in the cylinders due to wear, piston slap can occur. This is something that should be checked out right away.

Engine Noises Happening When the Car Is Hot

An engine ticking noise when the car is hot could indicate low oil pressure. Insufficient oil pressure can be damaging to an engine regardless of its age, so having a qualified mechanic take a look at it is highly advisable.

Why Does the Inside of My Car Smell Like Gas?

If the inside cabin of your vehicle smells like gasoline, it could be a sign that there may be more significant problems, and you should address them as soon as possible. While the smell of gas fumes on occasion isn’t as alarming, a strong odor from inside the vehicle should be investigated right away.

In this article, we will discuss potential reasons why the inside of your car smells like gas, such as possible fuel or exhaust leaks, a malfunctioning gas cap a failed pressure regulator, and more.

Fuel Leaks

If the smell of gasoline seems to be coming from the engine compartment, this could be a sign that there’s a leak in the fuel system. It is very important to have this checked out right away, as a leak in the fuel system could cause a fire under the hood.

Exhaust Leak

In contrast, if the gasoline smell seems to be coming from the car’s exhaust, this could be a sign of an exhaust leak. One of the main functions of a car’s exhaust system is to ensure drivers aren’t breathing in exhaust fumes. If you begin smelling gas fumes at the front of the vehicle near the engine or inside the cabin, the car’s exhaust system should be checked out.

Malfunctioning Fuel Cap or EVAP system

There is also a chance the gas smell in your car cabin is because of a faulty gas cap or EVAP (emissions) system. If your vehicle’s gas cap isn’t sealing correctly or is loose, damaged, or missing, gasoline fumes may escape through the fuel filler. Modern cars are also designed with EVAP systems to capture these gas fumes, so if that’s malfunctioning, it could be the source of the gas odor.

Failed Pressure Regulator

A failed pressure regulator may also leave your car with a gas smell. If the regulator is not working correctly, the vehicle’s fuel mixture may be off, causing an abundance of fuel to be present in the system. This will cause the car to run “rich”, which could produce a strong odor of gas in the passenger cabin.

Are Your Tires Ready For Winter?

With the winter season upon us, it is inevitable we will soon be dealing with colder temperatures, snow, and ice. Properly maintained tires are vital to the safety of your vehicle during the winter months. Your tires are your vehicle’s only contact with the road. Because of this, there are a few precautions you should take before the weather becomes unfavorable.

• All four of your tires should be the same type, size, tread pattern, speed rating, and load index. Differences in these factors can negatively affect a vehicle’s handling and stability.
• Proper inflation and pressure are imperative. Having inadequate tire pressure can cause unnecessary wear, as well as impact your vehicle’s fuel consumption. Keep in mind that as the temperature drops, so does the pressure in your tires. Make it a priority to check your tires’ pressure every few weeks in the winter.
• Have your tires checked for proper alignment and tread. This is something that should be done on a regular basis, but is most crucial to have done in preparation for winter.
• Make sure your tires are in good shape, or get new ones. Tires that are worn, cracked, or out of balance can seriously hinder your ability to drive and control your car. The majority of winter accidents are caused by loss of control of the vehicle on snowy or icy roads.
• Should you decide to get new tires, winter or snow tires are the best bet for those living in regions that have particularly cold and snowy winter months. Snow tires can provide up to 20% better snow traction than all-season tires. With snow tires, you receive the benefits of shorter braking distances as well as more predictable and controllable turning.
• If you choose not to purchase winter/snow tires, be sure to check the tread on your current tires. The next time you do purchase tires, check for deep grooves on the edges of the tires. These types of grooves move both snow and water outwards from underneath your tire, creating better handling and traction year-round.

Should your College Student Take their Car to School?

Back to school can be a time of big decisions for parents and students. One of the most difficult is whether or not to take a car away to college. Consider the following when making this decision:

• Responsible use – Has your child done his or her part in taking care of their vehicle so far? Have they driven safely and not had a problem with speeding tickets or accidents? Keep in mind the atmosphere of college inevitably means less supervision and more opportunities for poor decisions, so trust is a major factor.

• School policy – Colleges have varying policies on cars for students. Many universities don’t allow first-year students to bring cars to campus. If your student’s school does allow vehicles, the next thing to look into is parking. Will there be a nearby lot or deck they can park in, or will they have to park further away? If the parking area safe?

• Convenience to family – Does it make sense to the rest of the family that your student’s car be gone for semesters at a time? There could be younger siblings near or of driving age that may need the car.

• Jobs or internships – If your student has a part-time job or internship this fall, especially off-campus, then it is important they have a reliable means of transportation.

• Cost – Does your child have a way to pay for gas, parking permits, etc., or will you be covering that? Come up with a plan, such as you paying a certain percentage if your student maintains a certain GPA.

• Rules – Should you make the decision your student will take their car, establish some ground rules. Classmates will surely ask to borrow or drive the car at some point.

• Alternatives – Should you decide your student won’t take their car, there are several alternatives to having a car on campus to consider.

Get Summer Road Ready

Are you ready for the Summer?

Let the ASE Certified Techs at Car-X Tire & Auto make sure your vehicle is safe & road ready!

Get vacation ready w/ the following tips:

Battery– Have your battery checked along with the charging system. Most people feel that the cold is tough on a vehicle’s battery, but it is heat that truly wears a battery out!

Tires– Have your tires checked for wear and have them rotated if needed. Teen-agers really do not enjoy changing tires while on vacation. Swimming and boating is a lot more desirable to them then this activity.

Cooling system– Ensure that your coolant can handle the extra heat you will be asking it to absorb and make sure it is still protecting all the different metals in your engine. Have the belts and hoses checked as well. The number one reason for vehicle break down while on the road is a blown heater hose.

Fluids– Make sure that all critical fluids are full and ready to make the long trip with no problems along the way! This list includes engine oil, transmission fluid, brake and power steering fluid, and also differential fluid. Change any of these fluids that are at the end of their useful life.

A/C– No time is the air conditioning system needed more then during a long road trip with the family all on board the vehicle. Cooler inside temperatures usually mean cooler tempers and a lot more enjoyable road trip. The A/C system should be checked for proper performance including compressor operation along with the cooling fans. You need to ensure that vehicle will be properly cooled when the outside heat is 90 plus degrees. Most newer vehicles are now equipped with a cabin filter and this needs checked yearly especially if anyone in the family suffers from allergies. Lastly, the A/C system should be checked for any small leaks so that the A/C does not quit half-way through your fun filled vacation trip.

What to Keep in Your Car at All Times

Ask yourself this: If you were stuck with a flat tire, a dead battery, an empty gas tank, a blown gasket or any number of other car troubles, would you be prepared? Most drivers try not to think about the possibility of being in any of those situations, but the fact is it happens more often than what we would think. Throw in the factor of bad weather, especially come the winter months and that probability of getting stranded increases.

When these events occur having an emergency kit can make a large difference in your experience. Having some of these items can help you get yourself back on the road sooner than later or at least can help keep you safe until someone can come to the rescue.

There is no limit to what you can have in your emergency kit but there are some things that are essential to have. Below is a list of those essential items to keep in your vehicle:

Lighting – Flares, Flashlight, Reflective Lighting

No. 1 on your emergency kit checklist should be lighting. Reflective lighting triangle and flares will help notify other drivers of the roadside hazard. We suggest getting Led battery-operated flares, they are longer lasting and reusable. A flashlight is also very important to have on hand to help you investigate the issue with your car. It is important to keep extra batteries as well.

Jumper Cables/ Jump Starter

Car batteries often die or lose juice at the least opportune moments, having jumper cables can be the difference between waiting for 10 minutes to find another driver to jump your car or hours for a tow truck to get out to you. Another option is having a jump starter. This device acts like the battery of another vehicle with jumper cables directly attached. The instructions are the same procedure as jumping your battery with another person’s vehicle. Often these devices have multipurpose uses, some come with an air compressor and a flashlight attached. The only thing that you must make sure to do if you decide to get a jump starter is to make sure to charge it. Without a charge it will be useless, so it is always good to have a separate set of regular jumper cables.

First Aid Kit

The first aid kit is a must have item for your emergency kit. You can find prepack kits that will have all the essentials for small to more serious injuries. It is easy to injury yourself while trying to get your car back up and going. Be prepared for the worst and always hope for the best.

Blankets/Warm Clothing

These items are more essential in inclement weather conditions. If your car loses power completely and leaves you stranded on a winters day or evening the temperature in your car will decrease at a very fast pace. Make sure that you keep these items easily accessible to avoid leaving your car door open for longer than necessary, letting in the cold air

Spare Tire & Tools

Most of our vehicles have a spare tire or at least should. You should always double check to make sure you have a spare and to make sure that spare is properly inflated. A flat tire and a flat spare tire a recipe for disaster or having a properly inflated spare tire but no tools to switch out the tires. Ensure that you have the proper tools to use your spare tire when the time comes.

Avoid Getting Stranded!

What to do if…

…Your car won’t start

There are several possible reasons your car may not start, such as corroded cables or a light left on.

• If your car makes a clicking noise when you turn your key in the ignition – This type of sound usually indicates a dead battery. Have the battery checked and/or replaced by a certified technician.
• If your car is silent when you turn your key in the ignition – Check the battery cable connections and make sure they are tightened properly. Try starting your car again.
• If your car turns over but won’t start – Check your fuel supply. If you have plenty of gas, examine your spark plugs to ensure they are getting the electrical spark.
• If your car won’t start on cold days and your car has fuel injection – It will need professional assistance.
• If your battery seems alright – Failure to start problems can also be caused by bad ignition switches or starter connections. These can be examined and/or replaced by a certified technician.

Knowing how to jump start your car is important for if you ever do end up stranded.

1. Get out your jumper cables – Always carry a set up jumper cables in your car.

2. Find someone who is willing to assist you by using their car. Place both cars in park with the ignitions turned off and the emergency brakes on.

3. Remove the caps of both batteries.

4. Connect the cables to the two batteries. The red cable has positive clips on each end and the black cable has negative clips. They should be attached in the correct order. One of the red clips should be attached to the positive terminal of your battery. The other red clip should be attached to the positive terminal of the other person’s car. One of the black clips should be attached to the negative terminal of the other persona’s batter. The other black clip should be attached to an unpainted metal surface on your car that isn’t near the carburetor or battery.

5. Try to start your car. If it still won’t start, make sure the cables are connected properly and have the other person run their engine for a few minutes. Try to start your car again and if it still will not start, you battery may need to be replaced.

…Your car breaks down

Many things can cause you car to break down. If you feel your car experiencing a problem while driving, make every possible attempt to pull over to the right-hand shoulder of the road.

• Turn on your flashers. If it is nighttime, turn on your interior lights.
• If you were unable to make it to the side of the road, remain in your vehicle and call for help. Always try to carry a cell phone with you while driving.
• Many suggest hanging a cloth or piece of paper out of the drivers’ side window. This lets other drivers know your vehicle is in trouble and to go around you, as well as alerts any police officers or highway patrol that you are in need of assistance.
• If you are familiar with your car under the hood and want to look for what the problem may be, ensure you are far enough to the side of the road and stand only on sides of the car that are far enough away from traffic. Get back in your car as soon as you’ve looked around.
• If you are concerned about getting stranded, you may want to invest in a roadside assistance program such as AAA or OnStar, which can now get to you very easily by using GPS to track your location.

An important first step to any car trouble is to refer to your owner’s manual.

Tire Season Has Begun

October is Tire Month at Car-X! Why? It is the best time of year to pay attention to your tires and make sure they are ready for the coming winter months. The importance of tire maintenance cannot be underestimated – they are your vehicle’s only contact with the road.

• Have your tires inspected for proper wear and tread depth. Have them rotated if necessary according to your owner’s manual.

• Make sure your tires are in good shape. If they’re not, have them replaced. Tires that are worn, cracked, or out of balance can seriously hinder your ability to drive and control your car. The majority of winter accidents are caused by loss of control of the vehicle on snowy or icy roads.

• Depending on where you live, you may want to consider winter or snow tires. Snow tires can provide up to 20% better snow traction than all-season tires. With snow tires, you receive the benefits of shorter braking distances as well as more predictable and controllable turning.

• The valve caps on your tires are more valuable than you may think. They keep out any debris and prevent moisture from entering the tire, which can cause damage if the moisture freezes. This is especially critical for vehicles equipped with TPMS.

• All four tires should have the appropriate amount of inflation and pressure. This should be checked every few weeks once the weather gets cold, as the cooler temperatures cause the pressure in your tires to drop.

• Low tire pressure also negatively impacts gas mileage. According to a study done by the U.S. Department of Energy, having properly inflated tires can improve your gas mileage by up to 3.3%.

• When was the last time you checked your spare? Take a look at your spare tire to ensure it is in good condition. A time when you really need it is not a time to find out it is flat.

Making sure your tires are in good condition is important, especially when preparing for the winter months. Read our article about the other components of winterization.
