1996 PONTIAC FIREBIRD engine overheat

NOTICE:
When adding coolant it is important that you use
DEX-COOL (orange-colored, silicate-free) coolant meeting
GM Specification 6277111.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant
will require change sooner -- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL (orange-colored,
silicate-free) antifreeze that meets
GM Specification
6277M, which won’t damage aluminum parts. Use GM
Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture,
you don’t need to add anything else.
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant
mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you
or
others could be burned. Use a 50/50 mix of clean
water and DEX-COOL
TM (orange-colored,
silicate-free) antifreeze.

NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cos’t 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.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These
can be harmful.
Checking Coolant
When your engine is cold, check the dipstick on the cap
of the coolant recovery tank. The coolant level should
be at COLD, or a little higher. When your engine is
warm, the level on the dipstick should be up to HOT, or
a little higher.

it means you’re low on

Adding Coolant to the Recovery Tank
j,
If you need more coolant, add the proper mix at the
emban& recovery tank, but only when your engine is
cool. If the tank is very low or empty, also add coolant
to the radiator. See “Engine Overheating” in
the Index
for
information.
LAUTION:
”urning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn
you badly-
Never turn the pressure cap -- even a
little -- when the engine and radiator are hot.
Add coolant mix at the recovery tank, but be careful not
to spill it.
I
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.

Radiator Precsure Cap (All Engines)
NOTICE:
Your radiator cap is an 18 psi (124 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. 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.
Power Steering Fluid
3800 L36 Engine
When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid
unless you suspect there
is a leak in the system or you hear
an unusual noise. A fluid loss in this system could indicate
a problem. Have the system inspected and repaired.
