1997 PONTIAC FIREBIRD overheating

The traction control system warning light may come on
for the following reasons:
If you turn the system off by pressing the switch
located at the front
of the console the warning light
will come on and stay on and the light on the switch
will
go out. To turn the system back on, press the
switch again. The warning light should go off.
(See “Traction Control System” in the Index
for more information.)
If the temperature of the throttle control b’egins to
rise, the system will turn off and the warning light
will come
on until the system cools down. The
system does this to prevent damage from
overheating.
If the traction control system warning light comes on
and stays on for an extended period
of time when the
system
is turned on, your vehicle needs service.
Low Traction Light
When your anti-lock system
is adjusting brake pressure
to help avoid
a braking skid,
this light will come on.
LOW
TRAC
If you have the traction control system, this light will
also come
on when the system is limiting wheel spin.
Slippery road conditions may exist if the low traction
light comes on,
so adjust your driving accordingly. The
light will stay on for a few seconds after the anti-lock
system stops a’djusting brake pressure or the traction
control system stops limiting wheel spin.
The low traction
light also comes on briefly when you
turn the ignition
key to RUN. If the light doesn’t come
on then, have
it fixed so it will be there to tell you when
the anti-lock brake system or traction control system
is active.

Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature.
If the
gage pointer moves into the
red area, your engine is too
hot! It means that your
engine coolant has
overheated.
Low Coolant Light (VS Engine)
This warning light should
come on while you are
starting your engine.
If the
light doesn’t
come on, have
it repaired.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
In “Problems
on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index. Your
Firebird is equipped with
a LOW COOLANT
indicator which is designed to detect when the coolant
level drops below set limits. If the low coolant level
sensor (on the radiator) drops while the engine is
running,
the LOW COOLANT indicator will light and
remain lit until the ignition switch
is turned to the OFF
position. Check coolant level and add coolant as needed.
The LOW COOLANT light might stay on after filling
the radiator. Turn the ignition switch to the
OFF
position, then restart the engine to verify that the LOW
COOLANT light goes out. See “Engine Coolant” in
the Index.

NOTICE:
Driving with the LOW COOLANT light on could
cause your Pontiac
to overheat. See 66Engine
Overheating”
in the Index. Your Pontlac could
be damaged and
it wou1dn”t be covered by
your warranty.
Malfunction Indicator Lamp
(Service Engine Soon Light)
SERVICE
ENGINE
SOON
Your Pontiac is equipped with a computer which
monitors operation
of the fuel. ignition and emission
control systems. This
system is called
OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels
for the life
of the vehicle, helping to produce a cleaner
environment.
(In Canada, OBD 11 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE SOON
light comes on to indicate that there is a problem and
service
is required. Malfunctions often will be indicated
by the system before any problem is apparent. This may
prevent more serious damage
to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after
a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty,

Driving On Grades Making Turns
I NOTICE:
Making very sharp turns while trailering could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than
normal. Do
this so your trailer won’t strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.
Turn Signals When Towing a nailer
The green arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel will flash for turns even if the bulbs on
the trailer are burned out. Thus, you may think drivers
behind you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working. Reduce
speed and shift
to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes
so much
that they would get hot and
no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility
of engine and transmission overheating.
If you are towing a trailer and you have an automatic
transmission with overdrive, you may prefer to drive in
THIRD
(3) instead of AUTOMATIC OVERDRIVE (a)
(or, as you need to, a lower gear). Or, if you have a
manual transmission with FIFTH
(5) or SIXTH (6) gear
and you are towing a trailer, it’s better not to
use FIFTH
(5) or SIXTH (6) gear. Just drive in
FOURTH
(4) (drive in FIFTH (5) if you have a
six-speed manual transmission) or, as you need to,
a lower gear.

Engine Overheating
You will find a coolant temperature gage on your
Pontiac's instrument panel. You may also find a LOW
COOLANT warning light on your Pontiac instrument
panel
(V8 Engine only).
If Steam Is Coming From Your Engine
Steam from an overheated engine can L,m you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign
of steam or 'coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
-
NOTICE:
If your engine catches fire because yon keep
driving
with no coolant, your vehicle can be
badly damaged. The costly repairs
would not be
covered by your warranty.
5-14

Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine if there is a leak.
If you run
the engine,
it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered
by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine fans are running. If the engine
is overheating, both fans should be running. If they
aren’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
FULL COLD add a 50/50 mixture of clean water
(preferably distilled) and DEX-COOL@ (silicate-free)
antifreeze at the coolant recovery tank. (See “Engine,
Coolant’’
in the Index for more information.)
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@coolant.

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
“Scheduled Maintenance Services” 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. 12345977) or SAE
80W-90 GL-5 gear lubricant.
Limited-Slip Differential
To add lubricant when the level is low, use Axle
Lubricant (GM
Part No. 12345977). 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).
Engine Coolant
The cooling s stem in your vehicle is filled with new
DEX-COOL 8 engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240
000 km) whichever occurs first, if you add only
DEX-COOL’ extended life 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.
A
50150 mixture’ of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
e Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
