Abstract: A universal, direct drive fan coupling designed to attach a radiator cooling fan to a water pump of an internal combustion engine for an automobile or like vehicle wherein the subject coupling is specifically designed to efficiently replace the fan idling clutch present in many relatively current models of American made automobiles, or like vehicles. The inherent versatility of the subject direct drive coupling enables the elimination of any clutch mechanism normally found in the aforementioned automobile type which is positioned between the rotating shaft associated with the conventional cooling fan and a subsequently positioned and driven component of the circulation system such as the water pump.
