1994 PONTIAC FIREBIRD engine

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

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.
