Product Details

The Four Seasons 36963 is a severe duty thermal fan clutch designed for heavy-duty truck and commercial vehicle applications. This standard rotation fan clutch automatically controls engine cooling fan engagement based on temperature, improving cooling system efficiency while reducing engine load and conserving fuel.

Key Features:

  • Severe duty thermal design for demanding applications
  • Standard clockwise rotation pattern
  • 7.4-inch maximum clutch diameter
  • Precision-machined aluminum construction in raw aluminum finish
  • 6-bolt mounting pattern with 5/16-18 threaded holes and 6-inch bolt circle
  • 1.2-inch distance from clutch to mounting flange
  • Non-electronic thermostatic operation using silicone fluid coupling
  • Designed, tested, and built to OE specifications for proper fit and performance

This fan clutch is engineered to provide years of trouble-free operation, with each unit carefully inspected and tested before shipment. The thermal mechanism automatically engages the cooling fan at full speed when engine temperatures rise and allows reduced fan speed during cooler operation, minimizing parasitic power loss and reducing unnecessary noise. Backed by Four Seasons' 50+ years of mobile climate control experience.

Great so far

Cheapest priced ARP head studs on the internet. A++ I will definitely do more business with Autoplicity.

It was very easy,.....Thank You

Processed and shipped fast. I was a little upset with them shipping my Eibach springs in the Eibach box, and not repackaging it. Everyone could see the box, and knew what was in it. But this will not stop me from ordering again.

Found what I needed at an unbeatable price, easy purchase! No issues

The correct product that I ordered, and easy to find through there web site.thanks
