COOLING SYSTEM
The engine coolant level is maintained by a remote pressurized tank system.
The remote pressurized tank is connected to both radiators and provides a
single pressure cap and fill point for the vehicle.
WARNING
To avoid burns, allow the engine and coolant system to cool down before
opening the system. Never remove the pressure cap while the engine is warm
or hot. Escaping steam can cause burns.
NOTICE
The cooling system can cause audible liquid flowing noises as the vehicle
cools down after operation. This is considered normal 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.
NOTICE
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.
