Four Seasons Severe Duty Thermal Fan Clutch

The Four Seasons Severe Duty Thermal Fan Clutch is an engine cooling fan clutch. Four Seasons designed it for demanding applications such as towing, hauling and heavy-load operation. A thermal fan clutch, also called a temperature-controlled fan clutch or engine cooling fan clutch, adjusts the speed of the cooling fan to match engine temperature.

Key Features:

• Thermostatic design: the clutch engages the fan more fully as under-hood air temperature rises, and it lets the fan freewheel when less cooling is needed.
• Severe duty construction: built for tougher operating conditions than a standard fan clutch.
• Improved fuel economy and power: the fan runs at lower speed when cooling demand is low, which reduces parasitic engine load and fan noise.
• Replacement design: made as a direct replacement for the original fan clutch, so it installs without modification.

A worn or failing fan clutch can cause overheating, poor air conditioning performance or excessive fan noise. Replacing it helps keep engine temperatures stable.
