3.4.8 Flow Paths of Engine Cooling System
The engine coolant flows through the shell side of the
heat exchanger (or radiator), engine coolant pump, oil
cooler, turbo chargers, engine block and cylinder
head, jacket water heater, thermostat, expansion tank,
and coolant recovery tank (if equipped).
On heat exchanger equipped engines raw cooling
water flows through the tube side of the charge air
cooler, if equipped, and the tube side of the heat
exchanger.
Refer to Figures #21A for heat exchanger cooled
engines and #21B for radiator cooled engines for
cooling system flow path diagram.
