Radiator Pressure Cap
IVU I IIJt
Your radiator pressure cap is a 13
- i (90 kPa) pressure-type cap and
must be tightly installed to prevent
coolant
loss and possible engine
damage from overheating. Be sure
the arrows on the cap line up with
the overflow tube on the radiato
filler neck.
I
When you replace your radiator pressure
cap, an
AC* cap is recommended.
Thermostat
Engine coolant temperature is controlled
by a thermostat in the engine coolant
system. The thermostat stops the flow
of
coolant through the radiator until the
coolant reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
Power Steering Fluid
How to Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.

Engine Oil and Filter Change* - Always use SG
Energy Conserving I1 Oils of proper viscosity. The
SG designation may be shown alone or in
combination with others, such as SG/CC, SG/CD,
or SF, SG, CC, etc. To determine the preferred
viscosity for your vehicle’s engine (e.g., SAE
5W-30 or 1OW-30) see “Engine Oil’’ in the Index.
Engine Idle Speed Check* - Check the idle speed
and adjust it to underhood label specifications.
*An Emission Control Service.
The proper fluids and lubricants to use are listed in Section

3 Cooling System Service* - Drain, flush and refill
the system with new or approved recycled coolant
conforming to
GM Specification 4038M. Keep
coolant at
the proper mixture as specified. See
“Coolant”
in the Index. This provides proper freeze
protection, corrosion inhibitor level, and 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
pressure cap.
