Product Details

The Four Seasons 36726 is a standard thermal engine cooling fan clutch designed to regulate engine temperature by controlling cooling fan engagement. This thermal fan clutch uses a temperature-sensitive bi-metallic coil that expands with heat, allowing silicone oil to flow through the fluid coupling and engage the fan when additional cooling is needed.

Key Features:

  • Thermal fan clutch design provides automatic temperature-based fan engagement
  • Reverse rotation (counter-clockwise) configuration for specific vehicle applications
  • Standard duty construction suitable for vehicles without air conditioning
  • Meets or exceeds OEM specifications for reliable performance
  • Helps reduce engine warm-up time and optimize fuel efficiency
  • Minimizes fan noise and vibration during normal driving conditions

This fan clutch is engineered to prevent engine overheating while reducing unnecessary fan drag, which improves fuel economy and reduces wear on engine components. The thermal design ensures the fan only operates at full speed when cooling is required, providing quieter operation during cold starts and highway cruising.

Awesome prices

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

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
