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 0 104.
The vehicle may also display a
message on the Driver Information
Center (DIC). See Engine Cooling
System Messages 0 123.
If the decision is made not to lift the
hood but to get service help right
away, see Roadside Assistance
Program 0 318.
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.
