Coolant Reservoir: Description and Operation
Surge Tank Description
The radiator surge tank is only on the 6.5L Diesel engine and takes the place of the coolant reservoir found on gasoline engines. The primary function
of the surge tank is to allow air bubbles to escape from the cooling system and to allow proper cooling temperatures. The low coolant level sensor is
mounted on the side of the surge tank and is serviced by replacing the surge tank as a complete assembly.
