Downloaded from www.Manualslib.com manuals search engine A Word About Maintenance
We at General Motors want to help you keep your vehicle in good working
condition. But we don’t know exactly how you’ll drive it. You may drive
very short distances only a few times a week. Or you may drive long
distances all the time in very hot, dusty weather. You may use your vehicle
in making deliveries. Or you may drive it to work, to
do errands, or in many
other ways.
Because of all the different ways people use their GM vehicles, maintenance
needs vary. You may even need more frequent checks and replacements than
you will find in the schedules in this section.
So please read this section and
note how you drive. If you have any questions on how to keep your vehicle
in good condition, see your GM dealer, the place many GM owners choose
to have their maintenance work done. Your dealer can be relied upon
to use
proper parts and practices.
Your Vehicle And The Environment
Proper vehicle maintenance not only helps keep your vehicle in good
working condition, but it also helps the environment. All recommended
maintenance procedures are important. Improper vehicle maintenance or the
removal of important components can significantly affect the quality of the
air
we breathe. Improper fluid levels or even the wrong tire inflation can
increase the level of emissions from your vehicle. To help protect our
environment, and to help keep your vehicle in good condition, please
maintain your vehicle properly.
If you are skilled enough to do some work on your vehicle, you will
probably want to get the service information GM publishes. You will find a
list of publications and how to get them in Section
8, Customer Assistance
Information.
See “Service Publications” in the Index.
The Maintenance Record provides a place for you
to record the maintenance
performed on your vehicle. Whenever any maintenance is performed, be
sure to write it down in this section. This will help you determine when your
next maintenance should be done. In addition, it is a
good idea to keep your
maintenance receipts. They may be needed to qualify your vehicle for
warranty repairs.

needs, you’ll know that GM-trained and supported service people

Downloaded from www.Manualslib.com manuals search engine Explanation Of Scheduled Maintenance Services
Below are explanations of the services listed in the maintenance charts.

all necessary repairs done before you or anyone else drives the vehicle.
1.

5.
ENGINE OIL AND OIL FILTER CHANGE* - ALWAYS USE
API SERVICE SH OR SG ENERGY CONSERVING I1 OILS OF THE
PROPER VISCOSITY. The “SH” or “SG” designation may be shown
alone or in combination with others, such as “SHKD”, or
“SH, SG,
CD,” or “SG/CD”, etc.
To determine the preferred viscosity oil for your
vehicle’s engine (e.g. SAE
5W-30), see “Engine Oil” in the Index.
CHASSIS LUBRICATION - Lubricate the front suspension, ball
joint, steering linkage, and transfer case shift linkage, parking brake
cable guides, propshaft splines, universal joints, brake pedal springs,
and clutch pedal springs at the intervals specified on the proper
maintenance schedule, or at every engine oil change, whichever comes
first.
Ball joints should
not be lubricated unless their temperature is 10°F
(-12°C) or higher. When the weather is cold, let them warm up before
lubricating them
or they could be damaged.
Also, be sure to check all the vehicle fluid levels at this time.
COOLING SYSTEM SERVICE* - Drain, flush and refill the
system with new or approved recycled coolant conforming to “GM
Specification
603%”’. See “Engine Coolant” in the Index for the
proper coolant and mixture to use in your vehicle.
Also inspect
the hoses and replace them if they are cracked, swollen, or
deteriorated. Clean the outside of the radiator and air conditioning
condenser. Wash the radiator neck. To ensure proper operation,
pressure test the radiator and cap.
AIR CLEANER FILTER REPLACEMENT” - Replace at
specified intervals. Ask your dealer for the proper replacement
intervals for your driving conditions.
FRONT WHEEL BEARING REPACK (2-WHEEL DRIVE

Downloaded from www.Manualslib.com manuals search engine 13. TIRE AND WHEEL ROTATION AND INSPECTION - For
proper wear and maximum tire life, rotate tires at the first
6,000 miles
(10
000 kilometers) for Schedule I or 7,500 miles (12 500 kilometers)
for Schedule I1 and then every 15,000 miles
(25 000 kilometers)
thereafter. Follow the instructions and patterns shown in Section
6.
Check tires for uneven wear or damage. If irregular or premature wear
is apparent, check wheel alignment. Also, check for damaged wheels.
See “Tires” in the Index for more information.
14.
DRIVE AXLE SERVICE - Check readfront axle fluid level and add
as needed. Check constant velocity joints and axle seals for leaking.
Locking Differential - Drain fluid at first oil change and refill.
Check fluid
level and add as needed at subsequent oil changes. In
dusty areas or trailer towing applications, drain fluid at every
15,000 miles (24 135 kilometers) and refill.?
Standard Differential - Check fluid level and add as needed at
every oil change. In dusty areas or trailer towing applications,
drain fluid every
15,000 miles (24 135 kilometers) and refill.?
More frequent lubrication may be required for off-road use.
15. BRAKE SYSTEM INSPECTION - When the engine oil is changed,
inspect the lines and hoses for proper hookup, binding, leaks, cracks,
chafing, etc. Check the parking brake adjustment, and the fluid level in
the master cylinder. A low fluid level can indicate worn disc brake pads
which may need
to be serviced.?
When the wheels are removed for rotation, inspect disc brake pads for
wear and rotors for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including drums, wheel
cylinders, parking brake, etc. at the same time.
Inspect brakes more often if driving habits or conditions resul\
t in
frequent braking.
.L t A fluid loss in these systems may indicate a problem. Have them inspected
and repaired at once.
