(21) Radiator Bottom TankThe radiator is the cooling source of coolant for the cooling system. The radiator is made up of the following three sections. shunt tank for the radiator (1), radiator bottom tank (7), and radiator core assembly (6).The shunt tank (1) for the radiator is separate from the radiator. The tank is used in order to fill the cooling system, provides space for coolant expansion and removes air/gas from the system. Shunt line (14) connects to the shunt tank (1) to the inlet of the engines water pump (9). The shunt line provides a positive head pressure to the water pump as well and prevents cavitation. Coolant flows to the engine through the shunt line.The radiator bottom tank (21) is divided into two sections. The rear section accepts the return coolant from the water regulator housing (3). The front section is connected to the inlet of the water pump (9).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 (21). 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 inside 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.Radiator vent lines implemented to remove air or gas trapped in the cooling system. Vent line (radiator rear section) (5) removes gas from the highest point of the rear of the radiator cores (20). Vent line (radiator front section) (6) removes gas from the highest point of the front of the radiator cores (20) . Vent line (engine) (7) removes air and gas from the highest point of the engine.Reference: For additional information about the refrigerant condenser, refer to the Service Manual module Systems Operation, SENR5664, "Air Conditioning and Heating R-134a All Caterpillar Machines".Reference: For additional information about cooling the hydraulic system, refer to the Service Manual module Systems Operation, KENR7599, "Hydraulic Fan System".Reference: For additional information about cooling the steering system, refer to the Service Manual module Systems Operation, KENR7591, "General Information".Reference: For additional information about the axle oil cooler, refer to the Service Manual module Systems Operation, KENR7585, "Axle Oil Cooler".Transmission Oil Cooler
