Why is my check engine light on?

The check engine light is one of the most vital components to a properly functioning vehicle. It alerts the driver of potential problem on the vehicle’s onboard diagnostic system (main computer). When the check engine light comes on it means that a system in your vehicle – such as ignition, fuel injection, or emission control – is not operating efficiently, even though your vehicle seems to be running fine. If your check engine light comes on and its’ flashing, that indicates a more severe problem that should be checked immediately to prevent damage to the catalytic converter. If you see a flashing light, minimize driving at high speeds, especially if you’re towing. When the check engine light comes on, don’t panic; just make an appointment to get your vehicle checked out as soon as possible. Ignoring your check engine light could severely damage engine components and cost you more money in the end.

Should I drive my car when the check engine light is on?

It is possible but not too likely. However, you do need to get your vehicle check out as soon as possible. You may see a decrease in performance.

How do I know when my car needs a tune up?

You may see your gas mileage decrease. Your vehicle may start running rough. If your check engine light comes on that could also be an indicator that your vehicle needs a tune up.

What should I do if my car starts to overheat?

A car overheating is a very serious problem.  It your car overheats for too long, it could damage your engine. If this occurs, pull over to safe place and shut the engine off. Do not attempt to check the fluid level in the radiator; the hot fluid can cause severe burns. The best thing to do is have your car towed to ABZ Auto Care.

Should I consider using synthetic motor oil in my vehicle?

Synthetic motor oils can b e good choice for high output, turbocharged or supercharged engines or for vehicles that are used for towing, particularly during the hot weather, as well as vehicles that operate in extremely cold or hot climates.  Synthetic motor oils can improve fuel economy and provide longer intervals between changes.

Why does my brake pedal vibrate when I’m slowing down form freeway speeds?

The most common cause is excessive warping of the brake rotor, which is caused by improper tightening of the wheels or wheel hubs that are not properly cleaned when the rotors are installed after a brake job or tire rotation.

The problem may not be apparent right away – it may take a few hundred miles of driving or getting the brakes hot enough for the vibration to show up.  To tackle this problem, the mechanic must determine if the rotors are warped, the hubs are dirty, or if the hub is bad. If the hub is the problem it must be cleaned properly, the rotor reinstalled, and the smoothness and straightness rechecked.

Is it necessary to replace the timing belt at the recommended interval?

Yes, failure to replace the timing belt in many cars can result in major engine damage. The cost of repairing an engine with a broken timing belt is much greater that the cost of a timing belt replacement.

Why should I have a pre-purchase inspection on a car before I buy it?

When buying a pre-owned car, you want to make sure that you don’t get more than you’ve bargained for. ABZ Auto Care can provide you with a thorough inspection.  We can ensure that the vehicle is sound mechanically by checking the engine, drive train, belts, and hoses. We will also do a comprehensive safety check on the brakes and look for suspension damage and wear. A thorough inspection will not only help to ensure your safety, but you’ll be armed with additional information when negotiating a sale price.

How much extra fuel is burned when using air conditioning?

It is estimated that the use of air conditioning in a typical car reduces fuel economy by one to two miles per gallon. For larger cars, or when traveling in extreme heat, air condition cuts fuel economy up to four miles per gallon.
