ABSTRACT:
A fan drive for the cooling fan of an internal combustion motor vehicle in which the temperature of the engine coolant is constantly sensed and, in response to a sensed predetermined coolant temperature, heated air is directed by a blower through a conduit from a heat sink adjacent the exhaust manifold to the temperature sensing element of the fan drive. The heated air impacting on the temperature sensing element causes the element to react in a sense to engage the fan drive and cool the coolant.
