When to Check and What to Use
Refer to the Maintenance
Schedule
to determine how
often you should check the
fluid level
in your clutch
master cylinder reservoir and for
the proper fluid.
See “Owner Checks
and Services” and
“Recommended Fluids
and Lubricants” in the
How tu Check
The proper fluid should be added if the level is at or
below the
STEP mark on the reservoir cap. See the
instructions
on the reservoir cap.
Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL TM (orange-colored, silicate-free) engine
coolant.
This coolant is designed to remain in your
vehicle
for 5 years or 100,000 miles (166 000 h),
whichever occurs first. The
following explains
your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating”
in the
Index.
A Sol50 mixture of water and the proper coolant for
your Pontiac will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 9 F ( 129 O C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.

NOTICE:
When adding coolant it is important that you use
DEX-COOL TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant will require change sooner --,at
30,000 miles
(50 000 km)'or 24 months whichever
occurs first.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL TM (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M, which won't damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don't need to add anything else.
.
Adding only plain water to your cooling system
can be dangerous. Plain water,
or some other
liquid like alcohol, can bo'il before the proper
coolant mix will. Your vehicle's coolant warning'
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn't get the overheat
warning. Your engine could catch
fire and you or
others could be burned. Use a 5060 mix of clean
water and
DEX-COOL (orange-colored,
silicate-free) antifreeze.

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
warranty. Too much water
in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add cooldnt more than four times a year,
have
your dealer check your cooling system,
I NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
Checking Coolant
The coolant surge tank is located on the passenger side
of the engine compartment.

Page 247 of 356
A CAUTION:
Turning the surge tank 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 surge tank pressure cap
-- even a
little -- when the engine and radiator are hot.
When your engine is cold, the coolant level should be at
the FULL
COLD mark, or a little higher.
If this light comes on,
means you’re low on engine
coolant.
See “LOW coolant Warning
Light” in the Index.
Adding Coolant
If you need more coolant, add the proper mix at the
surge tank, but only when the engine is cool.
I A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are .hot
enough. Don’t spill coolant on
a hot engine.
~~
When replacing the pressure cap, make sure it is tight.

Surge Tank Pressure Cap
NOTICE: ~~ ~
Your pressure cap is an 15 psi l(105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating,
When you replace your surge tank pressure cap, a GM
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
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless
you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and
repaired.
