damage a vehicle. To help avoid
this, install a towing dolly beneath the wheels that would otherwise be

side
of the axle inboard of the spring.

Engine Overheating
You will find a coolant temperature gage
or the warning light about
a hot engine
on your Pontiac’s instrument panel. See
the
Index under Coolant Temperature
Gage
and Coolant Temperature Warning
Light.
You will also find a low coolant warning
light on your Pontiac’s instrument panel.
If Steam is Coming from Your Engine:
/1 Steam from an overheated
L L 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 opening 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.

Engine Overheating (CONT)
If No Steam is Coming 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.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
180
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 your heater to full hot at the
highest fan speed and open the window as necessary.
3. Try to keep your engine under load
(in a drive gear where the engine
runs slower).
If you no longer have the overheat
warning,
you can drive. Just to be safe,
drive slower for about ten 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
OFF THE 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.

Cooling System
When you decide it’s safe to lift the
hood, here’s what you’ll see:

(B) Electric engine fan

engine is not running and can injure you. Keep hands, clothing
and tools away from any
underhood electric fan.
[f the coolant inside the coolant surge
tank is boiling, don’t do anything else
until
it cools down.
’he coolant level should be at or above
TJLL COLD.
f it isn’t, you may have a leak in the
adiator hoses, heater hoses, radiator,

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. Engine damage
from

engine without coolant isn’
covered by your warranty.

You can be burned if you spill

Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Don’t spill coolant
on a hot engine.

system, including the coolant surge
tank pressure cap and upper radiator
hose, is no longer hot. Turn the
