Frequently Asked Questions

Electrical

Always replace burned-out fuses with ones of the same amperage (printed on the fuse) and note that if a fuse continues to “blow,” you should have the circuit checked professionally by one of our technicians for defects.

Battery cables and terminals should also be cleaned and inspected to make sure they provide a good electrical connection.

There are many sensors and computerized components that manage your vehicle’s engine performance and emissions. When one of these fails, the “check engine” light is illuminated. Although your car may seem to run fine, it is important to have the issue addressed to prevent long-term problems or failure of emission tests.

Engine

This is a very serious problem – if your car overheats for too long, you can damage your engine. As soon as possible, find a safe place to pull off the road and shut the engine off! Do not attempt to check the fluid level in the radiator as it can burn you. The best thing to do is have your car towed to a repair shop.

Fluid

Synthetic motor oils can be a good choice for high output, turbocharged or supercharged engines, vehicles that are used for towing (especially during hot weather), or vehicles that are operated in extremely cold or hot climates.

Synthetic motor oils, though several times more expensive than mineral-based motor oils, can improve fuel economy and provide longer intervals between changes. They also provide instant lubrication on start-up.

Milky brown engine oil is an indication of coolant in the oil. This can be caused by a blown head gasket (other gasket), a failed transmission cooler, or cracked casings. This condition is very serious and needs to be checked by a professional technician quickly.

You should get your oil changed every 3000 miles or as recommended in your vehicle’s owner’s manual. If intervals are extended, ensure you use oil that is capable of extended mileage changes.

Maintenance

Always replace burned-out fuses with ones of the same amperage (printed on the fuse) and note that if a fuse continues to “blow,” you should have the circuit checked professionally by one of our technicians for defects.

For maximum fuel economy and peak engine performance, your spark plugs should be replaced every 30 months or 30,000 miles, unless your vehicle is equipped with 100,000-mile platinum tipped spark plugs.

To help ensure dependable, trouble-free performance, replace your car’s fuel filter approximately every 30,000 miles or as recommended in your vehicle’s owner’s manual.

Timing Belt

YES. The failure of a 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 than the cost of a timing belt replacement.

Tires

Your tires should be rotated every other oil change, or every 5000 miles. Neglecting to rotate tires is a major cause of premature tire wear.

Technicians use special diagnostic tools to test and recalibrate sensors any time a tire is moved from one location on the vehicle to another. A sensor must be tested to make sure it is functioning correctly and also must be reprogrammed whenever tires are moved from one position to another during rotation. OEMs recommend a sensor service kit be installed every time a tire is serviced. These kits include replacement parts to properly service the sensor. Sensors are powered by a battery that usually has a life of 6 to 8 years. The sensor has to be replaced when the battery fails because the batteries are not replaceable.

An estimated 23,000 accidents and 535 fatal accidents annually involve blowouts or flat tires. Maintaining proper tire air pressure is not only a major safety concern, but can also affect the handling and performance of your vehicle.
