3. Fill the coolant surge tank with
the proper DEX-COOL coolant
mixture, to the COLD FILL line.
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. 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
DEX-COOL coolant mixture
to the coolant surge tank until
the level reaches the COLD
FILL line.
5. Replace the pressure cap.
Be sure the pressure cap is
hand-tight.
Check the level in the coolant surge
tank when the cooling system has
cooled down. If the coolant is not
at the proper level, repeat Steps 1
through 3 and reinstall the pressure
cap. If the coolant still is not at the
proper level when the system cools
down again, see your dealer.
Engine Overheating
The vehicle has an indicator to
warn of engine overheating.
There is an engine coolant
temperature warning light on
the vehicle's instrument panel.
See Engine Coolant Temperature
Gauge on page 510.
The decision may be made not
to lift the hood when this warning
appears, but instead get service
help right away. See Roadside
Assistance Program (U.S. and
Canada) on page 138 or Roadside
Assistance Program (Mexico) on
page 1310.
