Coolant from the engine comes in at the end. The
coolant goes through the many long tubes that are in
cooler (1). After the coolant goes through the tubes,
it goes out through the other end of the cooler and

comes in at the side of the cooler. The flow of oil is
around and along the many tubes inside the cooler. In
this procedure, heat is removed from the oil and is
given to the coolant of the engine. The engine coolant
goes through the tubes inside the cooler and takes the
heat from the oil. The coolant is then cooled by the
cooling system of the engine.
After the oil goes along the tubes in the cooler, it
goes out through the outlet passage at the bottom and
has a lower temperature. The colder oil then goes to
the transmission for lubrication and cooling.
Hydraulic system oil with a high temperature
comes from torque converter outlet (2). This oil
