(1) Power Train Oil Cooler (2) Coolant Outlet (3) Coolant Inlet (4) Inlet for Power Train Oil (5) Outlet for Power Train Oil | |
Power train oil cooler (1) is mounted vertically on the right side of the engine. The oil cooler is a water to oil type cooler. The oil cooler uses the coolant from the engine cooling system to cool the oil.
The engine coolant enters the oil cooler at inlet (3) of the oil cooler. Coolant flows through the tubes in the cooler. The coolant removes heat from the oil. The coolant then flows out of the oil cooler through outlet passage (2) of the oil cooler. The coolant is then cooled by the engine cooling system.
High temperature power train oil enters the cooler from the torque converter outlet relief valve. This oil enters the oil cooler at inlet (4) at the bottom of the oil cooler. The oil flows along the tubes in the oil cooler.
The heat is removed from the oil and the heat is transferred to the engine coolant. The coolant temperature is cooled by the engine cooling system. The power train oil exits through outlet passage (5) at the top of the oil cooler. The oil now has a cooler temperature.
The cooled oil then flows to the lubrication distribution manifold. The lubrication distribution manifold divides the flow between the transmission and brakes for lubrication and for cooling.
