Other Maintenance Items
Hydraulic Clutch Grease Fitting
If you have the 4.3L (VIN code Z) engine with a manual transmission, a
grease fitting is on the clutch housing for lubricating the cl\
utch fork ball stud.
Refer to the Maintenance Schedule for information on how to lu\
bricate the
clutch housing, and what type of lubricant to use. Be sure no\
t to over-fill
because you could
damage your clutch.
Front Suspension and Steering Linkage
Refer to the Maintenance Schedule to determine how often to lubricate the
fittings and what type of lubricant to use.
Front Wheel Bearings (Two-Wheel Drive)
If your vehicle is two-wheel drive, it has wheel bearings that mu\
st be cleaned
and repacked.
Refer
to the Maintenance Schedule to determine how often this must be
done.
Single Belt Accessory Drive
Your new vehicle uses a serpentine belt that is lighter, and more durable than
systems with several belts.
The belt runs over or around the pulleys
on the engine. A tensioner is used
to keep the belt tight at all times. The tensioner also makes replacing the
belt easier.
If you need to replace the belt, be sure to get the correct
replacement belt. Your dealership or parts supplier can help yo\
u with this.
The Accessory Drive Belt Routing label on your vehicle will sh\
ow you how to
route the belt your vehicle uses.

Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle if you notice:
Engine misfiring
* Loss of performance
Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three- Way Catalytic Converter
Your vehicle’s three-way catalytic converter is designed to reduce \
the
pollutants in your vehicle’s exhaust. Use only unleaded fuel \
in your vehicle.
If
you use leaded fuel, you could damage your three-way catalytic \
converter, and other engine components.
The Malfunction Indicator (SERVICE ENGINE SOON) lamp on your instrument panel lets you know when your emission system needs \
service.
The light will come on briefly when you start your engine to let you know
that the system is working.
If it does not come on when you start your
engine, or
if it comes on and stays on while you’re driving, your system \
may
need service. Your vehicle should still be driveable, but you should have your
system serviced right away.

Rinse the section with a clean, wet sponge.
Wipe off what’s left with a slightly damp paper towel or c\
loth.
Then dry it immediately with an air hose, a hair dryer or a heat lamp.
Wipe wlrh a clean cloth.
Using Solvent-Type 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 it, then:
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 an air hose, hair dryer, or heat lamp to help prevent a cleaning ring. (See
.
previous NOTICE.)
Special Cleaning Problems
Greasy or Oily Stains: Like grease, oil, butter, margarine, shoe polish, coffee
with cream, chewing gum, cosmetic creams, vegetable oils, wax c\
rayon, tar and asphalt.
Carefully scrape off excess stain.
Then follow the solvent-type instructions above.
Shoe polish, wax crayons, tar and asphalt will stain if left on a vehicle
seat fabric. They should be removed as soon as possible. Be c\
areful, because the cleaner will dissolve them and may cause them
to bleed.
Non-Greasy Stains: Like catsup, coffee (black), egg, fruit, fr\
uit juice, milk,
soft drinks, wine, vomit, urine and blood.
Carefully scrape off excess stain, then sponge the place with cool water.
If a stain remains, follow the foam-type instructions above.

Downloaded from www.Manualslib.com manuals search engine If an odor lingers after cleaning vomit or urine, treat the area \
with a
watedbaking soda solution:
1 teaspoon (5 ml) of baking soda to 1 cup
(250 ml) of lukewarm water.
Finally, if needed, clean lightly with solvent-type cleaner.
Combination Stains: Like candy, ice cream, mayonnaise,
c i sauce and
unknown stains.
Carefully scrape off excess stain, then clean with cool water and allow to
dry.
If a stain remains, clean it with solvent-type cleaner.
Cleaning Vinyl or Leather
Just use warm water and a clean cloth.
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 solvent-type vinylheather cleaner.
Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces of the instrument
panel. Sprays containing silicones or waxes may cause annoying \
reflections in
the windshield and even make it difficult to see through the windshield under
certain conditions.
Care of Safety Belts
Keep belts clean and dry.
I
CAUTION
I
A
Do not bleach or dye safety kits. If you do, it may severely weaken
them. In a crash they might not be able to provide adequate
protection. Clean safety belts only with mild
soap and lukewarm
water.
Glass
Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or
a liquid household glass cleaner will remove normal tobacco smo\
ke and dust
films.
Don’t use abrasive cleaners
on glass, because they may cause scratches.
Avoid placing decals on the inside rear window, since they may have to be
scraped off later.

Headlights
The headlight wiring is protected by a circuit breaker in the \
light switch. An electrical overload will cause the lights to go on and
off, or in some cases to
remain
off. If this happens, have your headlight wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker a\
nd a fuse. If
the motor overheats due to heavy snow, etc., the wiper will s\
top until the
motor cools. If the overload is caused by some electrical problem and not
snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows a\
nd other power
accessories. When the current load is
too heavy, the circuit breaker opens
and closes, protecting the circuit until the problem is fixed \
or goes away.
Trailer Wiring Harness
The optional seven-wire trailer wiring I ;s is protected by an in-line fuse
in the battery feed wire. This fuse is near rhe junction bloc\
k. See “Trailer
Wiring Harness” in the “Features
& Controls’’ section.
Fuse Block

Downloaded from www.Manualslib.com manuals search engine Be sure to use the correct fuse. If you ever have a problem on the road and
don’t have a spare fuse, you can “borrow” one of the correct value. Just pick
some feature of your vehicle that you can get along without-like the radio or
cigarette lighter-and use its fuse,
if it is of the value you need. Replace it
as soon as you can. See “Fuses and Circuit Breakers” in this section.
