Cooling System - Pontiac 1994 Grand Am Owner's Manual

If No Steam 1s 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:
0
Climb a long hill on a hot day.
0
Stop after high speed driving.
0
Idle for long periods in traffic.
Tow a trailer.
[f 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 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.
[f 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
4ND 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.
