Engine Coolant Heater (Option)
[n very cold weather, 0°F (- 18 "C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged in a minimum
of
four hours prior to starting your vehicle,
I'o Use the 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.
P
A CAJT,,J:
Plugging the cord into an ungrounded outlet
coul'd 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. After you've used the coolant heater, be sure to
store the
cord as it was b'efore 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 Pontiac dealer
in the area where you'll be puking
your vehicle. The dealer can give
you the best advice for
that particular area.

The air conditioner compressor operates in MAX, A/C,
BI-LEVEL, BLEND and DEFROST when the outside
temperature is above freezing. When the air conditioner
is on, you may sometimes notice slight changes
in your
vehicle’s engine speed and power. This is normal because
the system .is designed to cycle the compressor on and off
to keep
the desired cooling and help fuel economy.
Cooling
The air conditioner works best if you keep your
windows closed.
On very hot days, open the windows
just long enough for the hot air to escape.
1. Turn the air control knob to A/C for normal cooling.

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
+20 O F/-8 O C or lower) to improve
heater performance on start up. Because an engine
coolant heater warms the engine coolant, your vehicle’s
‘heating system can more efficiently provide heat for the
passenger area
of your vehicle. 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

Pontiac's flow-through ventilation system
supplies outside air into the vehicle when it is moving.
Outside air will also enter the vehicle when the
blower
fan is running.
Ventilation Tips
0 Keep the hood and front air inlet free of ice, snow or
any other obstruction (such
as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.
0 When you enter a vehicle in cold weather, turn the
fan control knob to the right for a few moments
before driving off. This helps clear the intake ducts
of snow and moisture, an'd reduces the chance of
fogging the inside of your windows.
0 Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That
is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on with your headlamps. Let the heater
run for awhile.
Then, shut the engine
off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.

Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found on the driver's door tells you the proper size,
speed rating and recommended inflation pressures for
the tires on your vehicle.
It also gives you important
information about the number of people that can be in
your vehicle and the total weight
that you can carry.

If No Ste~ n Is C Jminp From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when
you:
Climb a long hill on a hot day.
0 Stop after high-speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for, a minute or so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hbt at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@) or
DRIVE
(D) for automatic transmissions.
If you no longer have the overheat warning, you can
drive.
Just to be safe, drive slower for about 10 minutes.
If the warning doesn’t come back on, you can
drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see
if
the warning stops. But then, if you still have the
warning,
turn oflthe engine and get everyone out of the
vehicle
until it cools down.
You may decide not to lift the hood but to get service
help right away.

An electric 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 recovery tank is boiling,
don’t do anything
else until it cools down.
When it is cool, remove the coolant recovery tank cap
and
look at the dipstick.
The coolant level should be at 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.

5-16
ProCarManuals.com

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 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
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 TM
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant” in the Index for
more information.)
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 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 TM antifreeze.

NOTICE:
.In cold weather, water can freeze and crack the
engine, radiator, heater core
and other parts.
Use the recommended coolant and the proper
coolant
mix.

You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn
if the engine parts are hot
enough. Don't
spill coolant on a hot engine.
When the coolant in the coolant recovery tank is at
FULL COLD, start your vehicle.
If the overheat warning continues, there's one more
thing you can try. You can add the proper coolant mix
directly to the radiator, but be sure the cooling system is
cool before you do it.
