Abstract
A water-cooled remote fan assembly having an extra pulley set mounted between a water drive mechanism and a cooling fan for creating a second overdrive mechanism used to increase the rotational speed of the fan relative to the engine input speed. This provides the pulley-driven engine cooling system with improved cooling capabilities at low engine speeds. By decreasing the radius of one of the pair of auxiliary pulleys mounted to a transfer drive mechanism relative to the radius of a crankshaft pulley , the transfer drive mechanism can rotate at a faster rate than the crankshaft pulley . One or both of the pair of auxiliary pulleys may be mounted on a shroud of the radiator to provide better fan orientation and higher efficiencies for fan performance.
