(1) Radiator outlet (2) Transmission oil cooler (3) Bypass line (4) Water pump inlet (5) Water pump (6) Hydraulic oil cooler (7) Engine oil cooler (8) Cylinder block (9) (10) Coolant outlet from turbochargers (11) Coolant inlet to turbochargers (12) Aftercooler (13) Regulator housing (14) Radiator inlet (15) RadiatorCoolant from radiator (15) is pulled through radiator outlet (1) and water pump inlet (4) by water pump (5). At the water pump outlet, the coolant flow is diverted in three directions. Part of the coolant goes to the hydraulic oil cooler (6) and to aftercooler (12). The coolant then flows through the aftercooler and into the top of the cylinder block (8). The coolant then flows to each side of the cylinder block.Another part of the coolant goes to transmission oil coolers (2) and to the front of the cylinder block. Coolant at the front of the cylinder block then goes to each side.The remainder of the coolant from the water pump goes through engine oil cooler (7) to the side of cylinder block (8) .The coolant flows through the water jackets and around the cylinder liners from the bottom to the top. The hottest temperature is at the top of the cylinder liners. In this area, the water jacket is made smaller. This shelf (smaller area) causes the coolant to flow faster for better liner cooling. Coolant from the liners goes into cylinder heads (9) and around the hottest components. Coolant goes to the top of the cylinder head and to an elbow at each cylinder head. The coolant flows to the water manifolds at each bank of cylinders. Coolant goes through the water manifolds to the temperature regulator housing (13) .Regulator housing (13) has an upper and a lower section. The regulator housing uses four temperature regulators. The sensing bulbs of the four temperature regulators are in the coolant in the lower section of the housing. Before the regulators open, cold coolant is sent through the lower section of the housing and through bypass line (3) back to the inlet of water pump (5). As the temperature of the coolant increases, the regulators start to open. Coolant flow in the bypass line is stopped, and coolant flow is now sent through the regulator outlet to radiator inlet (14).
