Detailed Description
Four Seasons 46162 is a new engine cooling fan clutch engineered as a thermal replacement for vehicles that use a compact clutch package and reverse rotation. The 6.45-inch overall diameter, 3.13-inch overall height, and 0.63-inch pilot dimensions help identify the correct application before installation.

Installation Notes
Verify overall height, pilot diameter, bolt circle, and thread size before installation. Confirm reverse rotation and thermal operation match the original cooling fan clutch specification. Use the vehicle fitment notes for 1991-1993 Buick Roadmaster applications that require fan clutch height less than 3 inches.
