3-76. EXPANSION TANK AND WATER CONNECTIONS - MAINTENANCE INSTRUCTIONS.
a. The expansion tank (heat exchanger) provides a means of filling the engine cooling system as well as space
for expansion of the coolant as its temperature rises. An over flow pipe, attached near the top of the tank, provides a vent
to the atmosphere.
b. In this system the hot coolant flows from the water manifold to the expansion tank (heat exchanger) and down
through the vertical cells of the heat exchanger core. While raw water flows horizontally between the cells and lowers the
temperature of the coolant. The coolant is then circulated through the cylinder block and head by the fresh water pump.
c. The engine coolant level should be maintained near the top of the expansion tank (heat exchanger).
d. The expansion tank (heat exchanger) receives coolant from the water manifold, exhaust manifold and raw
water pump. The expansion tank (heat exchanger) returns coolant to the system thru the fresh water pump and lube oil
cooler.
