Radiator Pressure Cap (All Engines)
NOTICE:
Your radiator cap is a 18 psi (124 kPa)
pressure-type cap and must be tightly
installed to prevent coolant loss and
possible engine damage from over-
heating. Be sure the arrows on the
cap line up with the overflow tube
on the radiator filler neck.
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.

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.

When using concentrated washer
fluid, follow the manufacturer’s
instructions for adding water.
Don’t mix water with
ready-to-use washer fluid; Water
can cause the solution to freeze
and damage your washer fluid
tank and other parts of the washer
system. Also, water doesn’t clean
as well as washer fluid.
Fill your washer fluid tank only
3/4 full when it’s very cold. This
allows for expansion, which could
damage the tank if it is completely
full.
Don’t use radiator antifreeze in
your windshield washer. It can
damage your washer system and
paint.

Explanation of Scheduled
Maintenance Services
Following are explanations of the services
listed in Schedule I and Schedule
II.
The proper fluids and lubricants to use are
listed in Section
D. Make sure whoever
services your vehicle uses these. All parts
should be replaced and all necessary
repairs done before you or anyone else
drives the vehicle.
NOTE: To determine your engine’s
displacement and code, see
“Engine Identification” in the
Index.

Chassis Lubrication
- Lubricate
the suspension and steering
linkage. Lubricate the
transmission
shift linkage.
Tire and Wheel Rotation and
InsDection
- For proper wear
and maximum tire life, rotate
your tires following the
instructions in this manual. See
“Tires, Inspection and Rotation”
in the Index. Check the tires for
uneven wear or damage. If you
see irregular or premature wear,
check the wheel alignment.
Check for damaged wheels also.
Engine Accessorv Drive Belt!s)
InsDection
- Inspect the belt(s)
for cracks, fraying, wear and
proper tension. Replace as
needed. (Belts can have many small cracks in individual ribs
without affecting performance.)

NO. SERVICE
5 Cooling: System Service* -
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”
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 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.

WHAT SHOULD BE DONE
Now and then, make sure all your belts, buckles, latch plates, retractors, anchorages and

that might keep a restraint system from doing its job, have it repaired.
Inspect the front and rear suspension and steering system for damaged, loose or missing parts,
signs of wear, or lack of lubrication. Inspect the power steering lines and hoses for proper
hookup, binding, leaks, cracks, chafing, etc.
Inspect the complete exhaust system. Inspect the body near the \
exhaust system. Look for broken,
damaged, missing
or out-of-position parts as well as open seams, holes, loose connections or , ’;;
other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes :~
