coolant level PONTIAC FIREBIRD 1994 Owners Manual

During initial start-up only, if your
vehicle is eduipped with an optional
engine coolant heater, you can
use i't in
cold weather (around
+20°F/-8" C or
lower) to heat the passenger areq better
than without it. Because an engine coolant
heater warms the engine coolant, your
vehicle's Heating system can more
efficiently provide heat for the passenger
area
of your vehicle. See "Engine Coolant
Heater" in the Index.

On the V8 engine you’ll see this:
1. Coolant recovery tank
2. Radiator pressure cap
3. Electric engine fans
If the coolant inside the coolant recovery
tank is boiling, don’t do anything else
until it cools down.
When it
is cool, remove the coolant
recovery tank cap and look at the dipstick.
The coolant level should be at
or above
“FULL
COLD.” If it isn’t, you may have
a leak in the radiator hoses, heater hoses,
radiator, water pump or somewhere else
in the cooling system.
NOTICE:
Engine damage from running your
engine without coolant isn’t covered
by your warranty.
If there seems to be no leak, check to see
if the electric engine fan is running. If the
engine
is overheating, the fan should be
running.
If it isn’t, your vehicle needs
service.

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but
the coolant level isn’t at or above the
“FULL COLD’ mark, add a 50/50
mixture of clean water (preferably
distilled) and a proper antifreeze at the
coolant recovery tank. (See “Engine
Coolant” in the Index for more
information about the proper coolant
mix.)
NOTICE:
I
In cold weather, water can freeze
and crack the engine, radiator,
heater core and other parts. Use the
recommended coolant. When the coolant
in the coolant recovery
tank is at or above the “FULL COLD’
mark, start your vehicle.
If the overheat warning continues, there’s
one more thing
you can try. You can add
the proper coolant mix directly to the
radiator, but be sure the cooling system is
cool before
you do it.

Start the engine and let it run until
you can feel the upper radiator hose
getting hot. Watch out for the engine
fan(s).
By this time the coolant level inside
the radiator filler neck may be lower.
If the level is lower, add more of the
proper
mix through the filler neck
until the level reaches the base of the
filler neck. Then
replace the pressure cap. At any
time during this procedure if coolant
begins
to flow out of the filler neck,
reinstall the pressure cap. Be sure the
arrows on the pressure cap line up likl
this.

4. Fill with the proper mix. Add coolant
until you see a steady stream of
coolant coming from the bleed valves.
5. Close the bleed valves.
i. Continue to fill the radiator up to the *

’. Rinse or wipe the spilled coolant from
the engine and compartment.
I. Start the engine and allow it to run in
idle
for approximately four minutes.
By this time, the coolant level inside
the radiator will be lower. Add more
of the proper mix through the filler
neck until the level reaches the bdse

If a Tire Goes Flat
[t’s unusual for a tire to “blow out” while
you’re driving, especially
if you maintain
your tires properly. If air goes out of a
;ire, it’s much more likely to leak out
jlowly. But if you should ever have a
‘blowout,” here are a few tips about what
:o expect and what to do:
[fa front tire fails, the
flat tire will create
3 drag that pulls the vehicle toward that
side. Take your foot off the accelerator
pedal and grip the steering wheel firmly.
Steer to maintain lane position,
then
gently brake to a stop well out of the
traffic lane.
A rear blowout, particularly on a curve,
acts much like a
slud and may require the
same correction you’d use in a skid. In
any rear blowout, remove your foot from
the accelerator pedal. Get the vehicle
under control by steering the way you
want the vehicle to go.
It may be very
bumpy and noisy, but you can still steer.
Gently brake to a stop, well
off the road
if possible.
[f a tire goes flat, the next section shows
how to use your jacking equipment to
change a flat tire safely.

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 Appearanc’e Care
The proper coolant for your Pontiac will:
0
Give freezing protection down to
-34°F (-37°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
1825M,” which won’t damage aluminum
parts. You can also use a recycled coolant
conforming to GM Specification 1825M
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 war-
ranty. Too much water in the mix can
freeze and crack the engine, radiator,
heater core and other parts.
Adding Coolant
To Check Coolant: When your engine is
cold, check the dipstick on the cap of the
coolant recovery tank. The coolant level should be “COLD,” or a little higher.
When your engine is warm, the level on
the dipstick should be up to
“HOT,” or a
little higher.

Service and Appearance Care
Radiator Pressure Cap (All Engines)
NOTICE:
Your radiator cap is a 18 psi (124 kPa)
pressure-type cap and must be tightly
installed to prevent coolant loss and
possible engine damage from over-
heating. Be sure the arrows on the
cap line up with the overflow tube
on the radiator filler neck.
When you replace your radiator pressure
cap,
an AC@ 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.

How to Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.
