Engine Overheating
You will find a coolant temperature gage or the warning
light about a hot engine on your vehicle’s instrument
panel. See “Coolant Temperature Gage” and “Coolant Temperature Warning
Light” in the Index.
If Steam Is Coming From Your Engine
1
A CAUTION:
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 you
open 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.
I
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.
5-15

If No Steam Is Coming From Your Engine
If you get the overheat waming 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.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed
and open the window as necessary.
3. If you’re in a trafEc jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@)
or DRIVE (D).
If you no longer have the overheat warning, you can
drive. Just to be safe,
drive slower for about 10 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 oflthe 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:

L
A CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can injure you. Keep hands, clothing and tools
away from any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down.
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Electric Engine Fans
5-17

The coolant level should be at or above the FULL
COLD mark.
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump
or somewhere else in
the cooling system.
A CAUTION:
Heater and radiator hoses, and other engine
parts,
can be very hot. Don’t touch them. If you
do, you coul 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 fied before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by
your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fans are running. If the
engine is overheating, both fans should be running. If
they aren’t, your vehicle needs service.

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the FULL COLD mark, add a
50/50 mixture of
clean water (preferably distilled) and DEX-COOL@
engine coolant at the coolant recovery tank. (See
“Engine Coolant” in the Index for more information.)
I A CAUTION:
~
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water
or the wrong mixture,
your engine could get too hot but you wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned. Use
a
50/50 mixture of clean water and
DEX-COOL@ coolant.
I NOTICE:
In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
