Abstract
A shear liquid fan drive coupling for the radiator cooling system of an internal combustion engine of the type wherein a temperature responsive valve controls the degree of rotary coupling between the engine and a radiator cooling fan by controlling the active quantity of shear liquid in a liquid coupling between the engine and the fan. The specific improvement relates to a bi-metal strip for the temperature controlled fluid coupling, the strip being so configured that it cannot be mounted on the housing of the coupling except in a predetermined orientation therewith. In this manner, overheating of the engine due to faulty mounting of the bi-metal strip is precluded.
