(6) Radiator cores (7) Radiator bottom tankThe radiator is the source of coolant for the cooling system. The radiator is made up of the following three sections. shunt tank for the radiator, radiator bottom tank and radiator core assembly. The shunt tank for the radiator is separate from the radiator. The tank is used in order to fill the cooling system.The radiator bottom tank is divided into two sections. The rear section accepts the return coolant from the water regulator housing. The front section is connected to the inlet of the water pump.The radiator core assembly is made up of two paths with a connection between the paths at the top of each core. As the coolant is returned to the radiator, the coolant flows into the rear section of the bottom tank. The coolant flows up the core through the rear three tubes. As the coolant gets to the top of the core, the coolant flows through the crossover tank. Then, the coolant flows through the three front tubes to the front section of the bottom tank. As the coolant flows through the radiator cores in both directions and the air is pulled around the radiator core, the temperature of the coolant will be reduced.Also, the radiator assembly consists of the refrigerant condenser, the hydraulic oil cooler, the steering oil cooler, the axle oil cooler, the fuel cooler, and the aftercoolers.ReferenceFor additional information about the refrigerant condenser, refer to the Service Manual module Systems Operation, SENR5664, "Air Conditioning and Heating R-134a All Caterpillar Machines ".ReferenceFor additional information about cooling the hydraulic system, refer to the Service Manual module Systems Operation, RENR9787, "Hydraulic Fan System".ReferenceFor additional information about cooling the steering system, refer to the Service Manual module Systems Operation, RENR9787, "General Information".ReferenceFor additional information about the axle oil cooler, refer to the Service Manual module Systems Operation, RENR8910, "Axle Oil Cooler".Transmission Oil Cooler

Rear Left Side of the Machine (1) Engine oil cooler (2) Bonnet (3) Water pump (4) Bonnet (5) Oil inlet (6) Transmission oil cooler (7) Oil outlet (8) BonnetEngine coolant from water pump (3) flows through bonnets (2) and (8) to oil cooler (6). The coolant flows through long tubes inside the oil cooler to bonnet (4). The coolant then flows through bonnet (4) to the engine cylinder block.Transmission oil with a high temperature flows from the torque converter outlet to the oil cooler. This oil flows through oil cooler inlet (5) to the inside of the cooler. In this procedure, heat is removed from the oil and the heat is transferred to the coolant in the tubes. The engine coolant is then cooled by the cooling system of the engine.After the oil flows around the tubes, the oil flows to the other end of the oil cooler. The oil then flows out of the oil cooler through oil cooler outlet (7). This oil
