ABSTRACT:
A fluid coupling for an engine cooling system includes a driving member rotationably coupled to a driven member by a viscous fluid coupling. The viscous fluid coupling is controlled to vary the torque transfer from the driving member to the driven member as a function of a sensed engine liquid coolant temperature.
