THEORY OF OPERATION - CONTINUED
OIL COOLERS AND COOLING SYSTEM OPERATION - CONTINUED
Radiator Assembly. Radiator assembly is source of coolant for cooling system. Radiator is made up of radiator top
tank, radiator bottom tank, and radiator core assemblies. Also, radiator assembly includes air aftercooler and hydraulic
air cooler. Radiator top tank accepts return coolant from water regulator housing. Coolant flows from radiator top tank
down tubes of radiator core, then into bottom tank. As coolant flows through radiator core, air is pulled around core and
coolant temperature is reduced.
