1. You can remove the radiator pressure cap when the
cooling system, including the radiator pressure cap and upper radiator hose, is no longer hot.
Turn the
pressure cap slowly to the left 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. 3. After the engine cools, open the air bleed valves on
the heater return hose and water pump inlet.

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 Pontiac will:
Give freezing protection down to -34°F (-37 O C).
Give boiling protection up to 262 “F ( 128 ” C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets “GM
Specification
1825-M,” which won’t damage aluminum
parts.
You can also use a recycled coolant conforming to
GM Specification 1825-M 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 warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.

NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling,
speedometer/odometer calibration, headlamp
aim, bumper height, vehicle ground clearance,
and tire or tire chain clearance to the body and
chassis.
Used Replacement Wheels
Tire Chains
NOTICE:
If your Pontiac has P235/55R16, or P245/50ZR16
size tires, don’t use tire chains; they can dqpage
your vehicle.
If you have other tires, use tire chains only where
legal and only when you must. Use only
SAE
Class “S” type chains that are the proper size for
your tires. Install them on the rear tires and
tighten them as tightly
as possible with the ends
securely fastened. Drive slowly and follow the
chain manufacturer’s instructions.
If you can
hear the chains contacting your vehicle, stop and
retighten them.
If the contact continues, slow
down until
it stops. Driving too fast or spinning
the wheels with chains
on will damage your
vehicle.

Cleaning Your Convertible Top
NOTICE:
When using an automatic car wash, set your
heating or cooling system to “VENT” with the
fan speed set to the second highest speed. This
will prevent high pressure water from entering
around your top.
Your convertible top should be cleaned often. Use a
mild soap, lukewarm water and a soft brush. Don’t use
any harsh cleaners or bleaching agents on the top. They
can darnage the material.
When the top is really dirty, use a mild foam-type
cleaner. Use a cloth or sponge to remove the dirt.
Thoroughly rinse the top and dry it before lowering it.
A damp top causes wrinkles.
Aluminum Wheels (If So Equipped)
Your aluminum wheels have a protective coating similar
to the painted surface of your car. Don’t use strong
soaps, chemicals, chrome polish, abrasive cleaners
or
abrasive cleaning brushes on them because you could
damage this coating, After rinsing thoroughly, a wax
may be applied.
NOTICE:
If you have aluminum wheels, don’t use an
automatic car wash that has hard silicon carbide
cleaning brushes. These brushes can take the
protective coating
off your aluminum wheels.
Tires
To clean your tires, use a stiff brush with a tire cleaner.
When applying a tire dressing always take care to wipe
off any overspray or splash from painted surfaces.
Petroleum-based products may damage the paint finish.
