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.

The camper’s center of gravity should fall within the center of gravity zone for
your vehicle’s cargo load.
You must weigh any accessories, trailer hitches or other equipment you add
to your vehicle. Then, subtract this extra weight from the CWR,
This extra
weight may shotten the center of gravity zone for your vehicle. Your dealer
can help you with this.
If your slide-in camper and its load weigh less than the CWR, the center of
gravity zone for your vehicle may be larger.
Your dealer can help you make
a good vehicle-camper match. He’ll also help
you determine your CWR.
After you’ve loaded your vehicle and camper, drive to a weigh station and
weigh on the front and rear wheels separately. This will tell you the loads on
your
axles. The loads on the front and rear axles shouldn’t be more th\
an
either
of the GAWRs. The total of the axie..loads should not be more than
the GVWR.
Open your driver’s door and look at the door lock pillar f\
or the CertificationKire label to find out your GWAR and GWVR.
If you’ve gone over your weight ratings, move or take out some\
things until
all the weights fall below the ratings. Of course, you should always tie down
any loose items when you load your vehicle or camper.
When you install and load your slide-in camper, check the manufacturer’s
instructions.

Use this rotation pattern. Do not include “compact spare tire” in rotation, if so
equipped.
If your vehicle has front tires with different load ratings or tr\
ead designs (such
as all season vs. on/off road) than the rear tires, don’t \
rotate your tires front
to rear.
If you have styled steel or aluminum wheels, your spare is full-s\
ized, but its
appearance will not match your other wheels.
After the tires have been rotated, adjust the front and rear \
inflation pressure as shown on the CertificationRire label. Make certain that
all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the Index.
A
Rust or dirt on a wheel, or on the parts to which it is fastened, can
make the wheel nuts become loose after a time. The wheel coul\
d
come off and cause an accident. When you change a wheel, remove
any rust or dirt from 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. (See “Changing a Flat Tire” in t\
he Index.)

make sure they are the same size, load range, speed rating an\

Mixing tires
could cause you to lose control while driving. If you mix
tires of different types (like radial and bias-belted tires) the vehicl\

Uniform Tire Quality Grading
The following information relates to the system developed by th\
e United
States National Highway Traffic Safety Administration which grade\
s tires by
treadwear, traction and temperature performance. (This applies o\
nly to
vehicles
sold in the United States.)
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the
tire when tested under controlled conditions on a specified government test
course. For example, a tire graded
150 would wear one and a half (1 -1/2)
times as well on the government course as a tire graded 100. The relative
performance of tires depends upon the actual conditions of their use,
however, and may depart significantly from the norm due to var\
iations in
driving habits, service practices and differences in road charac\
teristics and
climate.
Traction-A, B, C
The traction grades, from highest to lowest are: A, B, and C. They represent
the tire's ability to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of asphalt and concrete.
A
tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight-ahead) traction tests and does not include cornering \
(turning) traction.
Temperature-A, B, C
The temperature grades are A (the highest), B, and C, representing the tire's
resistance
to the generation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified indoor laboratory test wheel,
Sustained high temperature can cause the material of the tire
to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire

failure. The grade C corresponds to a level of performance which all
passenger car tires must meet under the Federal Motor Vehicle \
Safety
Standard
No. 109. Grades B and A represent higher levels of performance on
the laboratory test wheel than the minimum required by law.
Warning: The temperature grade for this tire is established for\
a tire that is
properly inflated and not overloaded. Excessive speed, underinfla\
tion, or
excessive loading, either separately or in combination, can cause heat buildup
and possible tire failure.
These grades are molded on the sidewalls of passenger car tire\
s.
While the tires available as standard or optional equipment on \
General Motors
vehicles may vary with respect
to these grades, all such tires meet General
Motors performance standards and have been approved for use on \
General
Motors vehicles.
All passenger type (P Metric) tires must conform to Federal
safety requirements in addition
to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced carefully \
ar IT.-
factory to give you the longest tire life and best overall performance.
In most cases, you will not need
to have your wheels aligned again.
However,
if you notice unusual tire wear or your vehicle pulling one way \
or
the other, the alignment may need
to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels may need
to be
rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted. If wheel nuts keep
coming loose, the wheel, wheel bolts, and wheel nuts should be\
replaced. If
the wheel leaks air out, replace it (except some aluminum wheels, which can
sometimes be repaired). See your GM dealer
if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load carrying capacity, di\
ameter,
width, offset, and be mounted the same way as the one
it replaces.
If you need to replace any of your wheels, wheel bolts, or wheel nuts,
replace them only with
new GM original equipment parts. This way, you will
be sure you have the right wheel, wheel bolts, and wheel nuts\
for your
vehicle.

Putting a used wheel on your vehicle is dangerous. You can’t know

It could fail
suddenly and cause an accident. If you have to replace

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.
