If Your Engine Overheats
The pointer of your car's tempera-
ture gauge should stay in the mid-
range under most conditions. It may
go higher if you are driving up a long
steep hill on a very hot day. If it
climbs to the red mark, you should
determine the reason.
Driving with the temperature gauge
pointer at the red mark can cause
serious damage to your engine.
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.
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 warning indicators.
2. If you see steam and/or spray
coming from under the car or the
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 clue 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 mid-
point then continue driving.
4. If the temperature gauge stays at
the red mark, turn off the engine.
5. Wait until you see no more signs
of steam or spray, then open the
front hood and engine cover.
Taking Care of the Unexpected
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
