Product Details

Hayden Fan Clutch 2789 is part of the Hayden Fan Clutch line, focused on thermal fan drive control for trucks and vans that need dependable engine cooling under load. This severe duty design uses a hex mounting type, a 3.25-inch fan bolt circle, and a 1.44-inch mount diameter to match the specified OE-style fitment. The reverse-rotation configuration is important for applications that use a reverse-rotation cooling fan, including Ford F-150, F-250 Super Duty, E-Series vans, Expedition, Excursion, Navigator, and Mark LT models listed below.

This part cross-references Four Seasons 36719 for the same application.
