Caliso 22407 Heavy Duty Thermal Engine Cooling Fan Clutch

The Caliso 22407 is a heavy duty thermal engine cooling fan clutch engineered to maintain optimal engine operating temperatures by automatically regulating cooling fan speed in response to heat. This direct-fit replacement fan clutch is designed to meet or exceed original equipment specifications, providing reliable, long-lasting performance in demanding driving conditions.

A thermal fan clutch works by engaging the cooling fan at higher speeds when the engine reaches elevated temperatures, then partially disengaging when cooling demand is reduced — improving efficiency and reducing unnecessary engine load. The heavy duty designation means this unit is built for applications requiring enhanced durability beyond standard-duty parts, including vehicles used for towing, hauling, or frequent stop-and-go driving.
