How often do I need to change the oil in my
vehicle?
There are many variables that determine how often an oil change is
needed (climate, drive time, highway or city street driving, etc.) You
should refer to the Scheduled Maintenance section in your vehicle’s
owner’s manual.
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.
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.
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.
I have a belt making a very loud squeal on my
car. Should have it changed?
Inspect & replace belts regularly. The belt system in your car
helps such things as your alternator and air conditioning compressor to
operate correctly. When a belt breaks, they can cause costly damage. To
avoid this, inspect them regularly for wear. If they are showing signs, go
ahead and replace them before they become a problem.
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.
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 your local Chevrolet Dealership .
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.
How do I make sure my car battery has a good electrical connection?
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.
