1998 CHEVROLET CORVETTE engine oil

Downloaded from www.Manualslib.com manuals search engine Checking Brake Fluid
You can check the brake fluid without taking off the cap.
Just look at the brake fluid reservoir. The
fluid level should
be above the
MIN mark on the reservoir. If it isn’t, have
your brake system checked
to see if there is a leak.
After work is done on the brake hydraulic system, make
sure the level is between the
MIN and MAX marks.
What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part
No. 12377967). Use new brake fluid from a sealed
container only.
Always clean the brake fluid reservoir cap and the area around the cap before removing it.
This will help keep
dirt from entering the reservoir.
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.
NOTICE:
Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put
in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care” in
the Index.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts and wheel nuts
for replacement.
I NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire
clearance to the body and chassis.
A CAUTION:
Rust or dirt on the wheel, or on the parts to
which
it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use a cloth or paper towel to
do this; but be sure to use a scraper or wire brush
later,
if you need to, to get all the rust or dirt off.
I A CAUTION:
I
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.

Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flame if you strike a
match or get them on a hot part of the vehicle. Some are
dangerous if you breathe their fumes in a closed space.
When you use anything from a container to clean your
vehicle, be sure to follow the manufacturer’s warnings
and instructions. And always open your doors or
windows when you’re cleaning the inside.
Never use these to clean your vehicle:
Gasoline
Benzene
Naphtha
0 Carbon Tetrachloride
0 Acetone
0 Paint Thinner
Turpentine
0 Lacquer Thinner
0 Nail Polish Remover They can all be
hazardous
-- some more than
others
-- and they can all damage your vehicle, too.
Don’t use any of these unless this manual says you can.
In many uses, these will damage your vehicle:
0 Alcohol
0 Laundry Soap
Bleach
0 Reducing Agents
Cleaning the Inside of Your Vehicle
Use a vacuum cleaner often to get rid of dust and loose
dirt. Wipe vinyl or leather with a clean, damp cloth.
Your dealer has two cleaners, Multi-Purpose Interior
Cleaner and Capture Non-Solvent Dry Spot and Soil
Remover. They will clean normal spots and stains very
well. You can get GM-approved cleaning products from
your dealer. (See “Appearance Care and Materials” in
the Index.)

Clean up stains as soon as you can -- before they set.
Carefully scrape
off any excess stain.
Use a clean cloth or sponge, and change to a
clean area often.
A soft brush may be used if
stains
are stubborn.
If a ring forms after spot cleaning, clean the entire
area immediately or it will set.
Fabric Protection
Your Corvette has carpet that has been treated with
Scotchgard" Fabric Protector, a 3M product. It protects
fabrics by repelling oil and water, which are the carriers
of most stains. Even with this protection, you still need
to clean your carpet often to keep it looking new.
Further information on cleaning is available by calling
1-800-433-3296 (in Minnesota, 1-800-642-6167).
Cleaning Vinyl
Use warm water and a clean cloth.
0 Rub with a clean, damp cloth to remove dirt. You
may have to do it more than once.

don't get them
off quickly. Use a clean cloth and a
vinyVleather cleaner. See your dealer for this product.

dealer for this product.

Downloaded from www.Manualslib.com manuals search engine Your Corvette has a “basecoatlclearcoat” paint finish.
The clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that
are
non-abrasive and made for a basecoatklearcoat
paint finish.
NOTICE: I
Machine compounding or aggressive polishing on
a basecoat/clearcoat paint finish may dull the
finish or leave swirl marks.
1
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc., can
damage your vehicle’s finish if they remain on painted
surfaces. Wash the vehicle as soon as possible.
If
necessary, use non-abrasive cleaners that are marked
safe for painted surfaces to remove foreign matter.
Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their toll over a period
of years.
You can help to keep the paint finish looking
new by keeping your vehicle garaged or covered
whenever possible.
Cleaning Your Convertible Top
Your convertible top should be cleaned often. If you use
an automatic car wash, use one with water jets and
hanging cloths. High pressure car washes may cause
water to enter your vehicle.
When you hand wash the top, do it in partial shade. Use
a mild soap, lukewarm water and a soft sponge.
A
chamois or cloth may leave lint on the top, and a brush
can chafe the threads in the top fabric. Don’t use
detergents, harsh cleaners, solvents or bleaching agents.
Wet the entire vehicle and wash the top evenly to avoid
spots or rings. Let the soap remain on the fabric for a
few minutes. When the top is really dirty, use a mild
foam-type cleaner. Thoroughly rinse the entire vehicle,
then let the top dry in direct sunlight.
To protect the convertible top:
After you wash the vehicle, make sure the top is
completely dry before you lower it.
Don’t get any cleaner on the vehicle’s painted finish;
If you decide to go through an automatic car wash,
ask the manager if the equipment could damage
your top. it could leave streaks.

Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance can even
affect the quality
of the air we breathe. Improper fluid
levels or the wrong tire inflation can increase the level
of emissions from your vehicle.
To help protect our
environment, and to keep your vehicle in good
condition, please maintain your vehicle properly.
