cooling PONTIAC GRAND-AM 1995 Owners Manual

If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition off. Or, if the light comes on
and stays on
when you’re driving, stop as soon as possible and turn
the ignition
off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you’re driving, your Pontiac needs service.
If the
light
is on but not flashing and the regular brake system
warning light isn’t on, you still have brakes, but you
don’t have anti-lock brakes.
. Engine Coolant Temperature Warning
Light
This light tells you that your
engine coolant has
overheated or your radiator
cooling fan is not working.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn the engine
off as soon as possible.
HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road”, this manual shows what to
do. See “Engine Overheating” in the Index.

VENT Use when outside temperatures are mild,
and little heating or cooling is needed. Air flow is
through the instrument panel outlets. Set the center
control knob to the temperature desired.
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 “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.
9 BLEND: This setting divides air flow equally
between the heater ducts and the windshield defroster
vents.
DEFROST This setting directs air through the
windshield defroster vents located on top of the
instrument panel.
Defogging Windows
To defog the windshield, turn all three control knobs to
the
far right.
Air Conditioning System (Option)
The air conditioner and heater work best if you keep
your windows closed while using them. Your vehicle
also has the flow-through ventilation system described
later in this section.
Air Conditioning
Your system has three air conditioner settings. Before using
your
air conditioner on very hot days, open the windows
long enough to let hot inside
air escape. This reduces the
amount
of work your air conditioner’s compressor will have
to do, which should help fuel economy.
MAX: Use for maximum cooling. This setting
recirculates much of the air inside your vehicle
so it
maximizes your air conditioner’s performance and your
vehicle’s fuel economy.
A/C: Use for normal cooling on hot days. This setting
cools outside air and directs it through the instrument
panel outlets.
BI-LEVEL: Use on cool, but sunny days. This
setting brings in the outside air, but directs it in two
ways. The cool air is directed to the upper portion
of
your body through the instrument panel outlets, but
slightly warmer air is directed through the heater ducts
and defroster vents. At times this temperature difference
may be more apparent than others.

Ventilation
Use when outside temperatures are mild, and little
heating or cooling is needed.
Turn the right knob to
VENT. Air
flow is directed through the instrument panel
outlets. Set the center knob to the temperature desired.
Heating
Turning the right control knob to HEATER and the
center control knob clockwise will send heated air
through the heater ducts toward your feet and the
floor,
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
(- 18 O C) or lower, your heating system will more quickly
provide heat because the engine coolant ‘is already
warmed. See “Engine Coolant Heater” the Index.
BLEND: This setting divides airflow equally between
the heater ducts and the windshield defroster vents.
Defrosting
The DEFROST setting directs air through ‘the defroster
vents located on top of the instrument panel.
Defogging Windows with Air Conditioning
System
To defog the windshield, turn all three control knobs to
the far right.
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
air flow to the side vents, close the center vents.

If you drive regularly in steep country, or if you’re
planning to visit there, here
are some tips that can make
your trips safer and more enjoyable.
0 Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transaxle. These
parts can work hard on mountain
roads.
0 Know how to go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Shift to a lower gear when you
go
down a steep or long hill. Know how to go uphill. Drive in the highest gear
Stay in your own lane when driving on two-lane
possible.
roads in hills or mountains. Don’t swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hll, be alert. There could
be something in your lane, like a stalled car
or an
accident.
You may see highway signs on mountains that warn
of special problems. Examples are long grades,
passing or no-passing zones, a falling rocks area, or
winding roads. Be alert to these and take appropriate
action.

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system, and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you find them quickly. If you’re trailering, it’s
a good idea to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.

If the coolant inside the coolant surge tank is boiling,
don’t
do anything else until it cools down. 1
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.

ProCarManuals.com

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 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 a proper antifreeze
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 about the proper coolant
mix.)
I NOTICE:

NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
1. You can remove the coolant surge tank pressure cap
when the cooling system, including the coolant surge
tank pressure cap and upper radiator hose, is no
longer hot. Turn the pressure cap slowly about
one-quarter turn to the left and then stop.
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.

Hydraulic Clutch Refer to the Maintenance Schedule to determine how often you should check the fluid level in your clutch
The hydraulic clutch linkage in your vehicle is master cylinder reservoir and for the proper fluid. See
self-adjusting. The clutch master cylinder reservoir is “Owner Checks and Services” and “Recommended
filled with hydraulic clutch fluid. Fluids and Lubricants” in the Index.
It isn’t a good idea to “top off’ your clutch fluid. Adding
fluid won’t correct a leak. How to Check
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
When to Check and What to Use
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 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.
The proper coolant for your Pontiac will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 262 OF ( 128 O C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights work as they should.
