How to Add Coolant to the Radiator
(V6 Engine Only)
I NOTICE:
Your engine has a specific radiator fill procedure.
Failure to follow this procedure could cause your
engine to overheat and be severely damaged.
1. You can remove the pressure cap when the cooling
system, including the pressure cap and upper radiator
hose,
is no longer hot. Turn the pressure cap slowly
counterclockwise until
it first stops. (Don’t press
down while turning the pressure cap.)
If you hear a hiss, wait
for that to stop. A hiss means
there is still some pressure left.

2. Then keep turning the pressure cap, but now push
down
as you turn it. Remove the pressure cap.
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 to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
“Scheduled Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom
of the filler plug hole,
What to Use
Standard Differential
Use Axle Lubricant (GM Part No. 12345977) or SAE
80W-90 GL-5 gear lubricant.
Limited-Slip Differential
To add lubricant when the level is low, use Axle
Lubricant (GM
Part No. 12345977). To completely refill
after draining, add 4 ounces
(1 18 ml) of Limited-Slip
Differential Lubricant Additive (GM Part
No. 1052358).
Then fill to the bottom of the filler plug hole with Axle
Lubricant
(GM Part No. 12345977).
Engine Coolant
The cooling s stem in your vehicle is filled with new
DEX-COOL 8 engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240
000 km) whichever occurs first, if you add only
DEX-COOL’ extended life 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.
A
50150 mixture’ of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
e 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 only DEX-COOL@ (silicate-free) c’oolant.
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 ckan water (preferably
distilled)
and one-half DEX-COOL@ coolant which
won’t damage aluminum parts. If you use this mixture,
you don’t need to add anything else.
I
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 50J50 mix of clean
water and DEX-COOL’coolant.
6-30

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.
Checking 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.

Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced.
If the
wheel leaks air, replace
it (except some aluminum
wheels, which can sometimes be repaired). See your
Pontiac dealer if any
of these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new
wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel
bolts or wheel nuts, replace them only with new
CM
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.

Not all air conditioning refrigerants are the same.
If the air conditioning system in your vehicle needs
refrigerant, be sure the proper refrigerant is used.
If you’re not sure, ask your Pontiac dealer,
* Recheck fluid level after filling. See “Automatic
Transmission Fluid”
or “Manual Transmission Fluid”
in the Index.
** Recheck the oil level after filling. See “Engine Oil”
