Cooling System
The engine coolant level is maintained by a remote pressurized tank system. The remote pressurized tank is connected to the radiator and provides a single pressure cap and fill point for the vehicle.
The pressure tank is designed to contain a volume of air above the coolant level. As coolant operating temperature increases the coolant level in the pressure tank will rise and push out air past the pressure cap. As the engine coolant temperature decreases the coolant level in the pressure tank will lower and draw air back into the tank through the pressure cap.
TIP
Some coolant level drop on new vehicles is normal
as the system is purging itself of trapped air. Observe coolant levels
and maintain cold coolant level as recommended by adding coolant to
the pressure tank.
CAUTION
Escaping steam can cause burns. Never remove
the pressure cap while the engine is warm or hot. Always allow the
engine to cool before removing the pressure cap.
