coolant temperature PONTIAC FIREBIRD 1998 Owners Manual

4. Before starting the engine, be sure to unplug and store
the cord
as it was before to keep it away from moving
engine
parts. If you don’t, it could be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on
the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle.
The dealer can give you the best advice for that
particular area.
Automatic Transmission Operation
There are several different positions for your shift lever.
PARK (P): This locks your rear wheels. It’s the best
position to use when
you start your engine because your
vehicle can’t move easily.

Skip Shift Light (5.7L Engine)
When this light comes on,
you can only shift from
I SKIP SHIFT 1
FIRST (1) to FOURTH (4)
instead of
F'IRST (1) to
I I
This helps you get the best possible fuel economy.
The light will come on under these conditions:
The engine coolant temperature is greater than
you are going 15 to 20 mph (24 to 32 km/h) and
170°F
(77"C),
you are at 35 throttle or less.
When the
skip shift light is on, the gearshift lever will
let you
shift from FIRST (1) to FOURTH (4) only. Once
you are in FOURTH (4),
you can press the clutch again
and shift into another gear.
Follow the shift speeds listed below when the SKIP
SHIFT light is on.
Computer Aided Manual 'Jkansmission Shift Speeds
1st to 4th @ 15 mph (24 km/h)
4th to 5th @ 25 mph (40 M)*
5th to 6th @ 49 mph (64 km/h)**
Each time you come to a stop, the engine's Powertrain
Control Module (PCM) determines when
to activate the
SKIP SHIFT upshift system. Use SECOND (2) gear
only when you accelerate very quickly from a stop. You
can follow the full gear shift pattern.
*30 mph (48 km/h) when accelerating to
highway speeds.
**45 mph
(72 km/h) when accelerating to
highway speeds.

Low Traction Light
LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid
a braking skid,
this light will come on.
If you have the traction control system, this light will
also come on when the system is limiting wheel spin.
You may feel or hear the system working, but this is
normal. 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 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.
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.

Heating Ventilation
The heater works best if you keep your windows closed
while using it.
1. Turn the air control knob to heater.
2. Turn the fan control knob to the desired speed.
3. Turn the temperature control knob to a
comfortable setting.
During initial start-up only, if your vehicle
is equipped
with
an optional engine coolant heater, you can use it in
cold weather (around
2OoF/-8 “C or lower) to improve
heater performance
on start up. See “Engine Coolant
Heater” in the Index.
Bi-Level Heating
You may want to use bi-level heating on cool, but sunny
days. This setting directs cool air toward your body and
warmer air toward your feet.
1. Turn the air control knob to bi-level.
2. Turn the temperature control knob to a
comfortable setting.
3. Turn the fan control knob to the desired speed. For mild outside temperatures when little heating
or
cooling is needed,
you can still direct outside air through
your vehicle.
1. Turn the air control knob to vent.
2. Turn the temperature control knob to a
comfortable setting.
3. Turn the fan control knob to the desired speed.
Defogging and Defrosting
1. Turn the air control knob to defrost.
2. Turn the temperature control knob to the
desired setting.
3. Turn the fan control knob to the desired speed.

Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel. You may also
find a low
coolant warning light on your vehicle’s instrument panel
(5.7L V8 engine only).
If Steam Is Coming From Your Engine
I
Steam from an overheated engine can burn 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 you keep
driving with no coolant, your vehicle
can be
badly damaged. The costly repairs would not be
covered
by your warranty.
5-15

A 50/50 mixture of water and DEX-COOL@
coolant will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 “F (1 29°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
NOTICE:
When adding coolant, it is important that you
use only DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL 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. Damage caused by the
use of coolant other than DEX-COOL@
is not
covered by your new vehicle warranty.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL@ coolant which
won’t damage aluminum parts. If you use this mixture,
you don’t need to add anything else.
I A CAUTION:
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 mixture will. Your vehicle’s coolant
warning system is set
for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of clean water and
DEX-COOL@ coolant.
6-28

Radiator Pressure Cap (All Engines)
I 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, a GM 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, a GM thermostat
is
recommended.
Power Steering Fluid
The power steering fluid
reseivoir is locatei toward
the back
of the engine on
the driver’s side.
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.
How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then 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.
