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 ve\
ry
short distances only a few times a week. Or you may drive lo\
ng 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 re\
moval of
important components can significantly affect the quality of the air we breathe.
Improper fluid levels or even the wrong tire inflation can inc\
rease 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.
A
Performing maintenance work on a vehicle can be dangerous. In
trying to
do some jobs, you can be seriously injured. Do your own
maintenance work only
if you have the required know-how and the
proper tools and equipment for the job.
If you have any doubt, have
a qualified technician
do the work.
b
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.

Explanation Of Scheduled Maintenance Services
Below are explanations of the services listed in the maintenance charts.
The proper fluids and lubricants to use are listed in this se\
ction. Make sure whoever services your vehicle uses these. All parts should be \
replaced and all necessary repairs done before you or anyone else drives th\
e vehicle.
1. ENGINE OIL AND OIL FILTER CHANGE* -ALWAYS USE SG OR SG/CE QUALITY, ENERGY CONSERVING
II OILS OF THE PROPER
VISCOSITY. To determine the preferred viscosity oil for your vehicle’s
engine (e.g. SAE 5W-30). See “Engine Oil” in the Index.\

2. CHASSIS LUBRICATION -Lubricate the front suspension, ball joint,
steering linkage, clutch, and transfer case shift linkage, parki\
ng brake
cable guides, propshaft splines, universal joints, brake pedal s\
prings, and
clutch pedal springs at the intervals specified on the proper \
maintenance
schedule, or at every engine oil change, whichever comes first.\
On
vehicles without hydraulic clutches, lubricate the clutch cross \
shaft every
30,000 miles
(50 000 km).
Ball joints should not be lubricated unless their temperature i\
s 10°F
(-12°C) or higher. When the weather is cold, let them war\
m up before
lubricating them or they could be damaged.
Also, be sure to check all the vehicle fluid levels at this \
time.
3. CLUTCH FORK BALL STUD LUBRICATION (4.3L ENGINES ONLY)
-Lubricate the clutch fork ball stud through the fitting on th\
e clutch housing. Lubricant must be added “sparingly” to the fittin\
g, as only
.0066
Ib. (.003 kg) is required to lubricate the ball stud surface\
. Do not add
lubricant more often than the intervals recommended in the Main\
tenance
Schedules. Too much lubricant
will damage the clutch assembly.
4. COOLING SYSTEM SERVICE* -Drain, flush and refill the system wit\
h
new coolant. See “Engine Coolant’’ in the Index for th\
e proper coolant
and mixture to use in your vehicle.
Also inspect the hoses and replace them
if they are cracked, swollen, or
deteriorated. Tighten all hose clamps. Clean the outside of the radiator
and air conditioning condenser. Wash the radiator neck. To ensure proper
operation, pressure test the radiator and cap.

intervals. Ask your dealer for the proper replacement intervals for your
driving conditions.
6. FRONT WHEEL BEARING REP1 -;< (2-WHEEL DRIVE ONLY) -Clean
and repack the front wheel bearings at each brake relining, or at the
specified interval, whichever comes first.
7. TRANSMISSION SERVICE:
Automatic Transmission -Change the transmission fluid and filter \
every 15,000 miles (25
000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic.
Where the outside temperature regularly reaches 90°F (32°C) or
In hilly or mountainous terrain.
Frequent trailer pulling.
higher.
0 Uses such as taxi, police, delivery or other commercial service\
.
If the vehicle is not used mainly under any
of these conditions, change
the fluid and filter every 30,000 miles
(50 000 km). See “Automatic
Transmission Fluid” in the Index for more information.
Manual Transmission -Transmission fluid does not require periodic\

changing.
8. FUEL FILTER REPLACEMENT* -Replace the fuel filter at the specified
9. SPARK PLUGS REPLACEMENT* -Replace spark plugs with the type
interval
or sooner
if clogged.
listed in Section
6. See “Specification Charts” in the Index.
10. SPARK PLUG WIRE INSPECTION* -Clean wires and inspect for b\
urns, cracks or other damage. Check the wire boot fit at the distributor and \
at
the spark plugs. Replace wires as needed.
11. ENGINE TIMING CHECK AND DISTRIBUTOR CHECK* -Adjust timing to underhood label specifications. Inspect the inside and outsid\
e of the
distributor cap and rotor for cracks, carbon tracking and corro\
sion. Clean or replace as needed.
12. FUEL TANK, CAP AND LINES INSPECTION* -Inspect the fuel tan\
k, cap and lines for damage or leaks. Remove fuel cap, inspect g\
asket for
an even filler neck imprint, and any damage. Replace parts as \
needed.

Downloaded from www.Manualslib.com manuals search engine Scheduled Maintenance Services
13. ENGINE ACCESSORY DRIVE BELT INSPECTION*-Inspect belt. Look
for cracks, fraying, wear, and proper tension. Adjust or replac\
e as needed.
14. 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
II 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.
15. DRIVE AXLE SERVICE -Check rear/front axle fluid level and add \
as
needed. Check constant velocity joints and axle seals for leaki\
ng.
Locking differential -Drain fluid at first oil change and refill. Check
fluid level and add as needed at subsequent oil changes. In d\
usty areas
or trailer towing applications, drain fluid at every 15,000 miles
(24
135 kilometers) and refi1l.t
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 refil1.t
More frequent lubrication may be required for off-road use.
16. 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.t
When the wheels are removed for rotation, inspect disc brake p\
ads for
wear and rotors for surface condition. Also inspect drum brake \
linings for
wear and cracks. Inspect other brake parts, including drums, wh\
eel cylinders, parking brake, etc., at the same time.
Inspect brakes more often if driving habits or conditions resul\
t
in
frequent braking.
tA fluid
loss in these systems may indicate a problem. Have them inspected
and repaired at once.
