cooling PONTIAC FIREBIRD 1994 User Guide

Problems on the Road
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? pres5
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 keeb turning the pressure cap,
but now push down
as you turn it.
Remove the pressure cap.
5. After the engine cools, open the air
bleed valves on the heater return hose
and water pump inlet.

Hydraulic Clutch
The hydraulic clutch in your vehicle is
self-adjusting. The clutch master cylinder
reservoir is filled with hydraulic clutch
fluid.
It isn’t a good idea to “top
off’ your
clutch fluid. Adding fluid won’t correct a
leak.
A fluid loss in this system could indicate
a problem. Have the system inspected and
repaired.
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 Index.
How to Check:
The proper fluid should be added if the
level
is below the “STEP’ mark on the
reservoir. See the instructions on the
reservoir cap.
Rear Axle
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
“Periodic Maintenance Inspections” 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.
1052271) or SAE 80W-90 GL-5 gear
lubricant.
Limited-Slip Differential
To add lubricant when the.leve1 is
low, use Axle Lubricant (GM Part
No.
105227 1) or SAE 8OW-90 GL-5 gear
lubricant. 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) or SAE 8OW-90 GL-5 gear
lubricant.
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.

Service and Appearance Care
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned
and balanced carefully at the factory to
give you
the longest tire life and best
overall performance.
In most cases, you will not need to have
your wheels aligned again. However, if
you notice unusual tire wear or your
vehicle pulling one way or the other, the
alignment may need to be reset. If you
notice your vehicle vibrating when
driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or
badly rusted. If wheel nuts keep coming
loose, the wheel, wheel bolts, and wheel
nuts should be replaced. If the wheel
leaks air out, 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.
[f you need to replace any of your wheels,
wheel bolts, or wheel nuts, replace them
mly with new
GM original equipment
sarts. This way, you will be sure to have
:he right wheel, wheel bolts, and wheel
nuts for your Pontiac model.
NOTICE:
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer/odometer
calibration, headlight aim, bumper height, vehicle ground clearance, and tire or tire chain clearance to
the body and chassis.

Finish Care
Occasional waxing or mild polishing of
your Pontiac may be necessary to remove
residue from the paint finish.
You can get
GM approved cleaning products from
your dealer. (See “Appearance Care and
Maintenance Materials” in the Index.)
Your Pontiac has
a “basecoatjclearcoat”
paint finish. The clearcoat gives more depth and gloss to the colored
basecoat.Always use waxes and polishes
that are non-abrasive and made for a
basecoatklearcoat paint finish.
NOTICE:
Machine compounding or aggressive
polishing
on a basecoatjclearcoat
paint finish may dull the finish or
leave swirl marks.
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 damage 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 vehicle. 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 off the
protective coating.
Tires
Your Pontiac dealer has a GM White
Sidewall Tire Cleaner.
You can use a stiff
brush with the 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.
Weatherstrips
Silicone grease on weatherstrips will
make them last longer, seal better, and not
stick or squeak. Apply silicone grease
with a clean cloth at least every six
months. During
very cold, damp weather
more frequent application may be
required. (See “Recommended Fluids and
Lubricants’’ in the Index.)

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.

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.
