The cooling system in your vehicle is filled with new
DEX-COOL TM engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
‘(240 000 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 or if you need to add coolant to your
radiator, see “Engine Overheating” in the Index.
A $OB0 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 “F (129’ C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.

NOTICE:
When adding coolant, it is important that you
use only IBEX-COOL TM silicate-free coolant.
If silicated coolant is added to the system,
premature
engine, heater core or radiator
corrosion may result. In addition, the engine
coolant
will requipe 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 coolant which
won’t damage aluminum parts.
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 boil 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 50/50 mix of clean
water and
DEX-COOL TM coolant.
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 coolant more than four times a year,
have your dealer check your cooling system.
~~
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.

If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new
GM original
equipment
parts. This way, you will be sure to have
the right wheel, wheel bolts and wheel nuts
for your
Pontiac model.
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling
of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured.
Always use the
correct wheel, wheel bolts and wheel nuts for
replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer
or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for more
information.
