If Your Engine Overheats

The pointer of your car's temperature
gauge should stay in the midrange
under most conditions. It may go
slightly high if you are driving up a
long steep hill on a very hot day. If it
climbs to the red mark, you should
stop and determine the reason.
NOTICE
Driving with the temperature gauge
pointer at the red mark can cause
serious damage to your engine.
Taking Care Of The Unexpected
Table of Contents
Your car can overheat for several
reasons, such as lack of coolant or a
mechanical problem. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or spray
coming from under the car or engine
cover. In either case, you should take
immediate action.
Steam and spray from an over-
heated engine can seriously
scald you.
Do not open the hood or
engine compartment if steam
is coming out.
1. Safely pull to the side of the road.
Put the transmission in neutral or
Park and set the parking brake.
Turn off the climate control and all
other accessories. Turn on the
hazard indicators.
2. If you see steam and/or spray
coming from under the car or.
engine cover, turn off the engine.
3. If you do not see steam or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading
(climbing a long, steep hill on a
hot day with the A/C running, for
example), the engine should start
to cool down almost immediately.
If it does, wait until the tempera-
ture gauge comes down to the
white mark then continue driving.
