1998 PONTIAC GRAND AM coolant level

Low Coolant Warning Light
If this light comes on and
stays on, the vehicle should
be promptly pulled
off the
road and the coolant level checked. See “Engine
Coolant”
in the Index.
Malfunction Indicator Lamp
(Check Engine Light)
CHECK
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
If there are visible signs of steam see “Engine
Overheating’’
in the Index before opening the hood.
Have your vehicle serviced as soon
as you can.
This system is called OBD 11 (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. The
CHECK ENGINE 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.

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.

Heating Defrosting and Defogging
Turning the right control knob to HEATER and the
center CUR^^ knob to the right sends some heated air
through the heater ducts toward your feet, and some
through the defroster
vents.
VENT and HEATER are economical positions because
the air conditioner compressor doesn’t run in these
two
settings. This reduces engine load, resulting in improved
fuel economy. If either setting fails to keep you
comfortable, or causes your windows to fog up, turn the
right control
knob to one of the air conditioning
positions,
or to DEFROST.
If you have the optional engine coolant heater (engine
block heater) and
use it during cold weather, 0°F
(- 1 8 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.
To defrost the windshield, turn all three control knobs to
the far right.
The
DEFROST setting directs air through the defroster
vents located on top
of the instrument panel.
To warm passengers while keeping the windows clean,
use
BLEND.
To defog the side windows, turn the right control knob
to
BI-LEVEL and the fan control knob to HIGH. Aim
the side vents toward the side windows. For increased
airflow
to the side vents, close the center vents.

A CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can injure you.
Keep hands, clothing and tools
away from any underhood electric
fan.
If the coolant inside the coolant surge tank is boiling,
don’t
do anything else until it cools down.
I
The coolant level should be at or above FULL COLD.
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump or somewhere else in
the cooling system.
5-17

LA CAUTION: I
-1 -
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 cooling fan is running. If the
engine is overheating, the fan should be running. If it
isn’t, your vehicle needs service.
How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at or above FULL COLD, add a 50/50 mixture of
clean water (preferably distilled) and DEX-COOL@
coolant at the coolant surge tank, but be sure the cooling
system, including the coolant surge
tank pressure cap, is
cool before you do it. (See “Engine Coolant” in the
Index for more information.)
’ /$ CAUTION:
-
Steam and scalding liquids from a hot cooling
system
can blow out and burn you badly. They
are under pressure, and if you turn the coolant
surge
tank pressure cap -- even a little -- they
can come out
at high speed. Never turn the cap
when the cooling system, including the coolant
surge
tank pressure cap, is hot. Wait for the
cooling system and coolant surge
tank pressure
cap to cool if you ever have to turn the
pressure cap.
5-18

4. With the coolant surge tank pressure cap off, start the
engine and let it run until you can
feel the upper
radiator hose getting hot. Watch out for the engine
cooling
fan.
By this time, the coolant level inside the coolant
surge tank may be lower.
If the level is lower, add
more
of the proper mixture to the coolant surge tank
until the level reaches
FULL COLD, or just above
the small cylinder
at the base of the opening.
5. Then replace the pressure cap. Be sure the pressure
cap is tight.
Check the level in the surge
tank when the cooling
system has cooled down.
If the coolant isn’t at the
proper level, repeat Steps
1 to 3 and reinstall the
pressure cap or see your dealer.

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.
