engine coolant PONTIAC FIREBIRD 1997 User Guide

NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core
and other parts.
Use the recommended coolant and the proper
coolant
mix.
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. 1
When the coolant in the coolant recovery tank is at
FULL COLD 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.
~
1 A CAUTION:
Steam and sc’alding liquids from a hot cooling
system can
blow out and burn you badly. They
are under pressure, and
if you turn the pressure
cap
-- even a little I- they can come out at high
speed. Never turn the cap when the cooling
system, including the pressure cap, is hot. Wait
for the cooling system and pressure cap to
cool if
you ever have to turn the pressure cap.

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.

3. After the engine cools, open the coolant air
bleed valve.
3800 V6 (VIN Code M): There is one bleed valve. It
is located on the thermostat housing.
4. Fill.the radiatorwith the proper DEX-COOL@
coolant mixture, up to the base of the filler neck.
If you see a! stream of coolant coming from an air
bleed valve, close the valve. Otherwise,
close the
valve after the radiator is filled.

5. Then fill the coolant recovery tank to FULL HOT
6. Put the cap back on the coolant recovery tank, but
leave the radiator pressure cap
off.
7. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine fan( s).
8. By this time, the coolant level inside the radiator
filler neck
may be lower. If the level is lower, add
more of the proper DEX-COOL@ coolant mixture
through the filler neck until the level reaches the
base
of the filler neck.

9. 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

When you put the cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure you fully install the cap. The diagnostic system
can determine
if the fuel cap has been left off or
improperly installed. This would allow fuel to
evaporate into the atmosphere. See “Malfunction
Indicator
Lamp” in the Index.
1~ NOTICE: I
If you need a new cap, be sure to get the right
type. Your dealer can get one for you. If you get
the wrong type, it may not fit or have proper
venting, and your fuel tank and emissions
system
might be damaged.
