Drain, flush and refill the system
with new or approved recycled
coolant conforming to GM
Specification 1825M. Keep
coolant at the proper mixture as specified. See “Coolant”

Index. This provides proper
freeze and boil protection, corrosion inhibitor level and
maintains proper engine operating temperature.
Inspect hoses and replace if they
are cracked, swollen or deterior-
ated. Tighten screw-type hose
clamps. Clean the outside of the
radiator and air conditioning
condenser. Wash the pressure cap and neck.
To help ensure proper operation,
we recommend a pressure test of
both the cooling system and the
pressure cap.

Inspection
WHAT SHOULD BE DONE
Check the transmission fluid level; add if needed. See “Manual Transmission” in the Index.
A fluid
loss may indicate a problem. Check the system and repair if needed.
Check the gear lubricant level in the rear axle and add if needed. See “Rear Axle” in the Index.
A fluid loss may indicate a problem. Check the axle and repai\
r it if needed.
If your vehicle
is used to pull a trailer, have the rear axle gear lubricant changed every
7,500 miles
(12 500 km).
Inspect the complete system. Inspect brake lines and hoses for \
proper hookup, binding, leaks,
cracks, chafing, etc. 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, calipers, parking brake, etc. The parking brake\
is self-adjusting and no manual
adjustment is required. You may need to have your brakes inspected more often if your driving
habits or conditions result in frequent braking.
NOTE: A low brake fluid level can indicate worn disc brake pads which may need to be serv-
iced. Also, if the brake system warning light stays on or comes on, something may be wrong
with the brake system.
See “Brake System Warning Light” in the Index. If your anti-lock brake \
system warning light stays on, comes on or flashes, something may be wrong with the anti-lock
brake system. See “Anti-Lock Brake System Warning Light’’ in the Index.
