Drain, flush and refill the system
with new or approved recycled
coolant conforming to
GM
Specification
182SM.
Keep
coolant at the proper mixture
as
specified. See “Coolant” in the
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
deteriorated. 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
nressure cap.
