Frequently Asked Questions


Pro Automotive Car Repair - Frequently Asked Questions


How often should I rotate my tires?
Your tires should be rotated every other oil change, or every 6000 miles. Neglecting to rotate tires is a major cause of premature tire wear. 

What happens when my tires are not inflated to the proper level?
Tires that are under or over inflated can cause uneven tread wear, reduce the life of the tire, reduce traction and impact gas mileage, reducing your fuel economy. That’s why you should check your tire pressure at least once a month and adjust to the recommended pressure listed in your owner's manual. You can also find this information on a sticker in the trunk, on the door pillar, in the glove box or on your fuel door.

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

What does it mean if my "check engine" or "service engine soon" light comes on?
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.

How often should I change my wiper blades?
How often you should change your vehicle’s wiper blades depends on how much time your car spends indoors. If your car is kept mostly inside, then you should plan on changing your wiper blades once a year. However, if your vehicle is mostly outdoors, then it is important to change your wiper blades at least two times throughout the year. Properly maintained wiper blades guarantee clearer vision and safer driving.

How do I ensure that my car battery has a good electrical connection?
A Battery cables and terminals should be cleaned and inspected periodically to make sure they provide a good electrical connection.

When should I replace my car's fuel filter?
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.

When should I change my spark plugs?
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.

I have a burned out fuse, what should I do?
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.

How often do I need to check the anti-freeze? Does it need to be changed?
YES. Especially during summer, it is essential to check your vehicle’s anti-freeze once a month. Your vehicle’s anti-freeze fluids should be changed every 30,000 miles or every 2 to 3 years.

What should I do if my car starts to overheat?
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; the hot fluid can cause severe burns. The best thing to do is have your car towed to the nearest, trusted auto repair facility.

How Can I prevent my car from overheating this summer?
Radiator coolant, or anti-freeze as it is commonly known, works to combat both heat and cold. This helps to ensure your engine doesn't freeze or over-heat. Over time and with exposure to winter cold and summer heat, the protective components of this fluid are weakened and its effectiveness can be dramatically decreased. Check and service your car's cooling system at the intervals recommended in your owner’s manual.

Why are my brakes making noise?
Typically, noisy brakes indicate unsafe brakes, and once your brakes start making unusual sounds, it is extremely important to take your car into Pro Automotive for an immediate check-up.

How often should I get my oil changed?
You should get your oil changed every 3000 miles or more frequently if recommended in your vehicle's owner's manual.

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

Should I consider using synthetic motor oil in my vehicle?
Synthetic motor oils can be a good choice for high output, turbocharged or supercharged engines. Or for vehicles that are used for towing (especially during hot weather), and vehicles that operate in extremely cold or hot climates. Although more expensive than mineral-based oils, synthetic motor oils can improve fuel economy and provide longer intervals between changes.

How long will new, bottled engine oil last for?
An unopened container should be good for about 3 years. See the engine oil bible page for full details on this topic.
