Engine Overheating
If Steam is Coming from Your Engine:
You will find a coolant temperature gage
on your Pontiac's instrument panel.
If your engine catches fire becaus
you keep driving with no coolant,
your vehicle can be badly
damaged. The costly repairs woul
not be covered by your warranty.
Steam from an overheated
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.
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.
