Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel. You may also
find a low
coolant warning light on your vehicle’s instrument panel
(5.7L V8 engine only).
If Steam Is Coming From Your Engine
I
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.
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 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.
0 Stop after high-speed driving.
0 Idle for long periods in traffic.
0 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 traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@)
or DRIVE (D) for automatic transmissions. 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 ofthe 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.
5-16

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
FULL COLD add a 50150 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.)
a CAUTION:
-1
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.
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.
5-19

When the coolant in the coolant recovery tank is at
FULL COLD start your vehicle.
If the overheat
warning continues, there's one more
thing you can try. You can add the proper coolant
mixture directly to
the radiator but be sure the cooling
system
is cool before you do it.
'
A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it
will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.
F
A CAUTION:
Steam and scalding liquids from a hot cooling
system
can blow out and burn you badly. They
are under pressure, and if
you turn the radiator
pressure cap
-- even a little -- they can come out
at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap, is hot. Wait for the cooling system and
radiator pressure cap
to cool if you ever have to
turn the pressure cap.

How to Add Coolant to the Radiator
(3800 V6 Engine)
I NOTICE:
Your engine has a specific radiator fill procedure.
Failure to follow this procedure could cause your
engine to overheat and be severely damaged.
1. You can remove the radiator pressure cap when the
cooling system, including the radiator pressure cap
and upper radiator hose, is no longer hot.
Turn the
pressure cap slowly counterclockwise until it first
stops. (Don’t press down while turning the
pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.

How to Add Coolant to the Radiator
(VS Engine Only)
NOTICE:
The LS1 Engine (Code G) has a specific radiator
fill procedure. Failure
to follow this procedure
could cause your engine
to overheat and be
severely damaged.
1. You can remove the radiator pressure cap when the
cooling system, including the radiator pressure cap
and upper radiator hose, is
no longer hot. Turn the
pressure cap slowly
to the left (counterclockwise)
until it fist stops. (Don't press down while turning
the pressure cap.)
If you hear a hiss, wait for that to stop.
A hiss means
there is still some pressure left.

Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire and its wheel together. If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to
spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck,
NOTICE: but you must use caution.
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t use tire chains on your
compact spare.
A CAUTION:
m
If you let your tires spin at high speed, they can
explode, and you or others could
be injured.
And, the transmission or other parts
of the
vehicle can overheat. That could cause an
engine compartment fire or other damage.
When you’re stuck, spin the wheels
as little as
possible. Don’t spin the wheels above
35 mph
(55 kmh) as shown on the speedometer.
