ABSTRACT:
An adapter for attaching a radiator cooling fan to a water pump of an internal combustion engine, the adapter having spaced rear and front walls for attachment to the water pump and fan respectively with recesses extending radially into the body of the adapter between these walls for reception of a wrench used in securing the rear wall to the pump, and with these recesses being separated by radial projections securing the front and rear walls together, and with additional openings being provided in the front wall for passing a wrench rearwardly through that wall when necessary. The adapter has a rearwardly opening pilot recess for engaging a pilot projection on the water pump flange, and a forwardly projecting boss structure for centering the fan, which boss structure desirably has two external diameters for engaging fans with different size center openings, and with a spacer being provided for reception about the larger diameter portion of the boss structure to locate a fan having a smaller diameter central opening for proper engagement with the reduced diameter portion of the boss.
