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,

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.

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.

and repaired at once.
