engine oil CHEVROLET EXPRESS 1996 1.G Owner's Manual

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half
clean water (preferably
distilled) and one-half DEX-COOL
Rul (orange-colored,
silicate-free) antifreeze that meets
GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need
to add anything else.
’/d CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
’ get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use
a 50/50 mix of clean
water and
DEX-COOL TM (orange-colored,
silicate-free) antifreeze.

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.
Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the
brake pads are worn
and new pads are needed. The sound may come and
go or
be heard all the time your vehicle is moving (except when
you are pushing on the brake pedal firmly).
I
The brake wear warning sound means that
sooner or later your brakes won’t work well.
That could lead
to an accident. When you hear
the brake wear warning
sound, have your
vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.

Downloaded from www.Manualslib.com manuals search engine Using Solvent-’Qpe Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all.
Some spots and stains will clean off better with just
water and mild soap.
If
you need to use a solvent:
Gently scrape excess soil from the trim material with
a clean, dull knife or scraper. Use very little cleaner,
light pressure and clean cloths (preferably
cheesecloth). Cleaning should start at the outside of
the stain, “feathering” toward the center. Keep
changing to a clean section
of the cloth.
When you clean a stain from fabric, immediately
dry the area with a blow dryer
to help prevent a
cleaning ring.
Fabric Protection
Your GM has upholstery and 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 upholstery and carpet often to
keep
it looking new.
Further information on cleaning is available by calling
1-800-433-3296
(in Minnesota, 1-800-642-6 167).
Special Cleaning Problems
Greasy or Oily Stains
Stains caused by grease, oil, butter, margarine, shoe
polish, coffee with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar and asphalt can
be removed as follows:
1. Carefully scrape off excess stain.
2. Follow
the solvent-type instructions described earlier.
3. Shoe polish, wax crayon, tar and asphalt will stain if
left
on a vehicle’s seat fabric. They should be removed
as soon as possible. Be careful, because the cleaner will dissolve them and may cause them
to spread.

Stains caused by catsup, coffee (black), egg, fruit, fruit
juice, milk, soft drinks, wine, vomit, urine and blood can
be removed as follows:
1. Carefully scrape off excess stain, then sponge the
soiled area with cool water.
2. If a stain remains, follow the foam-type instructions
described earlier.
3. If an odor lingers after cleaning vomit or urine, treat
the area with a waterhaking soda solution:
1 teaspoon (5 ml) of baking soda to 1 cup (250 ml)
of lukewarm water.
4. If needed, clean lightly with solvent-type cleaner.
Combination Stains
Stains caused by candy, ice cream, mayonnaise, chili
sauce and unknown stains can be removed as follows:
0 Carefully scrape off excess stain, then clean with
cool water and allow to dry.
0 If a stain remains, clean it with solvent-type cleaner. 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.
Things like tar, asphalt and shoe polish will stain if
you don’t get them off quickly. Use a clean cloth and
a GM VinyULeather Cleaner or equivalent product.
Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap.
0 For stubborn stains, use a GM VinyVLeather Cleaner
or equivalent product.
cleaners, furniture polish or shoe polish
on leather.
0 Never use oils, varnishes, solvent-based or abrasive
0 Soiled leather should be cleaned immediately. If dirt is
allowed to work into the
finish, it can harm the leather.

Downloaded from www.Manualslib.com manuals search engine Finish Care
Occasional waxing or mild polishing of your vehicle by
hand may be necessary
to remove residue from the paint
finish. You can get GM-approved cleaning products
from your dealer. (See “Appearance Care and Materials”
in the Index.)
Your GM manufactured vehicle may have
a
“basecoat/clearcoat” 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 basecoat/clearcoat paint finish. 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.
I NOTICE:
Machine compounding or aggressive polishing on
a basecoat/clearcoat paint finish may dull the
finish or leave
swirl marks.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is usually
needed. However,
you may use GM Chrome Polish on
chrome or stainless steel trim, if necessary.
Use special care with aluminum trim.
To avoid
damaging protective trim, never use auto or chrome
polish, steam
or caustic soap to clean aluminum. A
coating of wax, rubbed to high polish,
is recommended
for all bright metal parts.

Introduction
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.
