{Warning
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. Never turn
the cap when the cooling system,
including the surge tank pressure
cap, is hot. Wait for the cooling
system and surge tank pressure
cap to cool.
If coolant is needed, add the proper
DEX-COOL coolant mixture directly
to the surge tank, but be sure the
cooling system is cool before this
is done. 1. When the cooling system, including the coolant surge
tank pressure cap and upper
radiator hose, is no longer hot,
remove the pressure cap.
Turn the pressure cap slowly
counterclockwise about
one-quarter turn and then stop.
If a hiss is heard, wait for that
to stop. A hiss means there is
still some pressure left. 2. Keep turning the pressure cap
slowly, and remove it.
3. Fill the coolant surge tank with the proper DEX-COOL coolant
mixture until the level inside
stabilizes at the cold fill line on
the front of the surge tank.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until the
upper radiator hose can be felt
getting hot. Any time during
this procedure, watch out for
the engine cooling fan.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge
tank until the level stabilizes at
the cold fill line on the coolant
surge tank.
5. Replace the pressure cap tightly.
Check the level in the surge
tank when the system has
cooled down. If the coolant is
not at the proper level, repeat Steps 1−4, then reinstall the
pressure cap. If the coolant is
not at the proper level when
the system cools down again,
see your dealer.
Caution
If the pressure cap is not tightly
installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is an engine coolant
temperature gauge on the
instrument cluster. See
Engine
Coolant Temperature Gauge 0105.
The vehicle may also display a
message on the Driver Information
Center (DIC). See Engine Cooling
System Messages 0125.

If the decision is made not to lift the
hood but to get service help right
away, seeRoadside Assistance
Program 0328.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fan is running. If the engine
is overheating, the fan should be
running. If it is not, do not continue
to run the engine and have the
vehicle serviced.
Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.
If Steam Is Coming from the
Engine
{Warning
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 the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam Is Coming from
the Engine
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.
Climbs a long hill on a hot day.
. Stops after high-speed driving.
. Idles for long periods in traffic.
If the overheat warning is displayed
with no sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the
highest fan speed. Open the
windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or
N (Neutral) and let the
engine idle.
If the temperature overheat gauge is
no longer in the shaded area or an
overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
