Abstract
A system for controlling the temperature of a vehicle drive train component utilizes coolant that is normally used to cool an engine on the vehicle. At least one flow passageway is associated with the drive train component housing. Coolant from the radiator is selectively allowed to flow through the passageway where it absorbs heat from within the drive train component. The fluid is then returned to the radiator where heat can be dissipated in a conventional manner. A suitably programmed controller preferably controls the amount of coolant fluid flow through the component and controls a fan assembly associated with the radiator to ensure appropriate cooling of the fluid to achieve desired engine cooling and drive train component cooling.
