(1) Power Train Oil Cooler (2) Outlet (3) InletPower train oil cooler (1) is located on the right side of the engine. Hot power train oil flows through the oil cooler from the torque converter to inlet (3) as engine coolant is pumped through the oil cooler. Outlet (2) is connected to the lubrication distribution manifold. From the lubrication distribution manifold, the oil lubricates the power train.Oil Flow

FIRST GEAR FORWARD (1) Power Train Oil Cooler (2) Outlet (3) Inlet (4) Torque Converter Outlet Relief Valve (5) Lubrication Distribution Manifold (FF) Activated Components (GG) Tank Oil (HH) Lubricating Oil (JJ) High Pressure (KK) First Pressure Reduction (PP) Torque Converter PressureHot oil from the torque converter outlet relief valve (4) flows through inlet (3) of the power train oil cooler (1). Oil exits power train oil cooler (1) through outlet (2). Outlet (2) is connected to lubrication distribution manifold (5). The cool oil is then used to lubricate the transmission and the brakes.Coolant Flow

(1) Power Train Oil Cooler (6) Water Pump (7) Engine Oil CoolerIllustration 3 is a schematic of the engine cooling system for the D8T Track-Type Tractor with the C15 engine.ReferenceSee Systems Operation, "Cooling System" in this module for information about engine coolant flow.Engine coolant is pumped by water pump (6) through engine oil cooler (7). Engine coolant then flows to power train oil cooler (1) from engine oil cooler (7). The engine coolant flows out of the power train oil cooler into the engine block.As a result, the power train oil that is flowing through the power train oil cooler (1) is cooled.
