Engine Coolant
The following explains your cooling
system and how to add coolant when
it
is low. If you have a problem with
engine overheating or if you need
to add
coolant to your radiator, see “Engine
Overheating” in the Index.
The proper coolant for your Chevrolet
will:
0 Give freezing protection down to
Give boiling protection up to 262°F
Protect against rust and corrosion.
0 Help keep the proper engine
Let the warning lights work as they
-34°F (-37°C).
(128°C).
temperature.
should.
What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets “GM Specification
1825M,” which won’t damage aluminum
parts.
You can also use a recycled coolant
conforming to GM Specification
1825M
with a complete coolant flush and refill. If
you use
this mixture, you don’t need to
add anything else.
NOTICE:
If you use an improper coolant mix,
your engine could overheat and be
badly damaged. The repair cost
wouldn’t be covered by your war-
ranty.
Too much water in the mix can
freeze and crack the engine, radiator,
heater core and other parts.

To Check Coolant:
When your engine is
cold, check the dipstick on the cap of the
coolant recovery tank. The coolant level
should be at
“COLD,” or a little higher.
When your engine
is warm, the level on
the dipstick should be up to
“HOT,” or a
little higher.
If you have the 5.7L LTI (Code P) engine
and this light comes on,
it means you’re
low on engine coolant.
To Add Coolant to the Recovery Tank:
If you need more coolant, add the proper
mix at the coolant recovery tank, but only
when your engine
is cool. If the tank is
very low or empty, also add coolant to the
radiator, see “Engine Overheating” in the
Index for information.

e CAUTION:
Turning the radiator pressure cap when the engine and radiator
are hot
can allow steam and scalding liquids
to
blow out and burn you badly.
Never
turn the pressure cap - even a
little
- when the engine and radiator
are hot.
Add coolant mix at the recovery tank, bul
be careful not to spill
it.
A CAUTION:
You can be burned if you spill
coolant on hot engine parts. Coolant
contains ethylene glycol,
and it will
bum if the engine parts are hot
enough. Don't spill coolant
on a
hot engine.
Radiator Pressure Cap (All Engines)
NOTICE:
Your radiator cap is a 18 psi
(1 24 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 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.

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.

Explanation of Scheduled
Maintenance Services
Following are explanations of the services
listed in Schedule
I and Schedule 11.
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 Accessory Drive Belt(s)
Inspection
- 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.)
ITEM
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.
* An Emission Control Service.
