Product Details

The Four Seasons 36786 is a heavy-duty thermal fan clutch designed for severe duty applications in trucks and commercial vehicles. This reverse rotation (counter-clockwise) fan clutch automatically regulates engine cooling fan speed based on temperature, improving fuel efficiency and reducing noise when maximum cooling is not required.

Key Features:

  • Severe duty thermal fan clutch rated for heavy-duty truck applications
  • Reverse rotation (counter-clockwise) design
  • Non-electronic thermal control for reliable operation
  • Precision machined aluminum construction with raw aluminum finish
  • Maximum clutch diameter of 7.4 inches
  • 4-bolt mounting pattern with M8 x 1.25 bolt holes
  • Fan bolt circle diameter of 3.81 inches (96.8mm)
  • Fan mount diameter of 3.25 inches (82.6mm)
  • OE performance, fit, and appearance

This fan clutch meets or exceeds OEM specifications and is designed for out-of-the-box installation. The thermal design engages the cooling fan when engine temperatures rise and disengages during cooler operation to improve efficiency and reduce engine load. Commonly replaces OEM part numbers including 15001827, 15130067, 15228375, 922843, and others.
