1998 PONTIAC GRAND AM coolant temperature

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
A CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three-prong 110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least 15 amps.
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.

Enhanced Traction System Active Light
When your Enhanced Traction System is limiting wheel spin,
this light will LOW
.TRAC
come on.
Slippery road conditions may exist if the Enhanced
Traction System active light comes on,
so adjust your
driving accordingly.
The light will stay on for a few seconds after the
Enhanced Traction System stops limiting wheel spin.
The Enhanced Traction System active 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 system is active.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature.
If the
gage pointer moves into the
too hot!
red area, your engine
is
A light
will come on to the right of the gage when the
gage pointer moves beyond the normal operating zone.
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.

Am
/J VENT: Use when outside temperatures are mild,
and little heating or cooling
is needed. Airflow is
through the instrument panel outlets. Set the center
control knob to the temperature desired.
‘fl HEATER: This setting brings heated air through
the heater ducts, and some through the windshield
defroster vents.
If you have the optional engine coolant heater (engine
block heater) and use it during cold weather, 0°F
(- 18 O C) or lower, your heating system will more quickly
provide heat because the engine coolant is already
warmed. See “Engine Coolant Heater” in the Index.
v# BLEND: This setting divides airflow equally
between the heater ducts and the windshield defroster vents.
w.
DEFROST This setting directs air through the
windshield defroster vents located on top of the
instrument panel.
Air Conditioning
On very hot days, open the windows long enough
to let hot, inside air escape. This reduces the time it
takes for your vehicle to cool down, which should help
fuel economy.
For quick cool-down on very hot days, use
MAX with
the temperature knob all the way in the blue area.
If the
setting is used for long periods of time, the air in your
vehicle may become too dry.
For normal cooling on hot days, use
A/C with the
temperature knob in the blue area. The system will bring
in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body,
but your lower body may not be warm enough.
You can use BI-LEVEL with the temperature knob in
the middle. The system will bring in outside air and
direct it to your upper body, while sending slightly warmed air to your lower body. You may notice this
temperature difference more at some times than
at others.

Engine Overheating
You will find a coolant temperature gage and a low
cooIant warning light
on your vehicle’s instrument
panel. See “Engine Coolant Temperature Gage”
and
“Low Coolant Warning Light” in the Index.
If Steam Is Coming From Your Engine
A CAUTION:
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.
I NOTICE: I
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.

When to Check and What to Use
Refer to the Maintenance Schedule to determine how
often you should check the
fluid level in your clutch
master cylinder reservoir
and for the proper fluid.
See “Owner Checks and
Services” and
“Recommended Fluids and
Lubricants” in the Index.
How to Check
The proper fluid should be added if the level is at or
below the
STEP mark on the reservoir cap. See the
instructions on the reservoir cap.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL 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, see “Engine Overheating” in
the Index.
J
A 50/50 mixture of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 OF (1 29 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as
they should.
6-25

Surge Tank Pressure Cap
I NOTICE:
~~
Your pressure cap is an 15 psi (105 kPa)
pressure-type cap and must be tightly installed
to
prevent coolant loss and possible engine damage
from overheating.
When you replace your surge tank pressure cap, a GM
cap is recommended.
Thermostat
Power Steering Fluid
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 ACDelco@
thermostat
is recommended.
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.

I Long Trip/Highway Maintenance Schedule I
0 Change automatic transaxle fluid and filter if the vehicle is mainly driven
under one or more of these conditions:
- In heavy city traffic where the outside temperature regularly reaches 90°F
(32°C) or higher.
- In hilly or mountainous terrain.
- When doing frequent trailer towing.
- Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these conditions, the fluid and
filter
do not require changing.
Manual transaxle fluid doesn’t require change.
