Product Details
Four Seasons Fan Clutch 46050 is engineered as a severe-duty thermal fan clutch for vehicles that need dependable engine cooling under load. The 7.4-inch clutch diameter, 1.86-inch mount diameter, and 3.81-inch fan bolt circle support a precise fit in the intended cooling fan drive setup. This part number is a direct replacement option for applications calling for a reverse-rotation, aluminum fan clutch with M8 x 1.25 threaded holes and a 2.08-inch distance from the clutch to the mounting flange.
For buyers searching for a Four Seasons 46050 fan clutch, a severe duty truck fan clutch, or a reverse rotation engine cooling fan clutch, this unit is built to match the requirements of heavy-duty cooling systems. It is also a relevant replacement for select vehicle applications such as Dodge Ram 2500 and Dodge Ram 3500 cooling fan clutch service where the original setup specifies this style and rotation.

Installation Notes and Tips
Verify reverse rotation, bolt pattern, pilot dimensions, and fan bolt circle before installation. Mounting hardware is not included, so reuse or source the correct hardware separately if required by the vehicle. Confirm clearance at the fan shroud and check that the mounting flange and pilot dimensions match the original cooling fan clutch specification.
