Caliso 22321 Heavy Duty Thermal Fan Clutch

The Caliso 22321 Heavy Duty Thermal Fan Clutch is a direct-fit replacement designed to restore proper engine cooling system performance. This thermal fan clutch regulates engine cooling fan speed based on engine temperature, engaging fully during high heat conditions and partially disengaging during normal operation to reduce parasitic power loss and improve fuel efficiency.

Key Features:

• Heavy-duty construction for extended service life and reliable performance under demanding conditions
• Thermal engagement automatically modulates fan speed in response to engine temperature
• Direct OE replacement engineered to meet or exceed original equipment specifications
• Precision-balanced to minimize vibration and reduce strain on water pump bearings
• Seals and internal components built to resist heat, oil, and coolant contamination

A failing fan clutch can cause engine overheating, excessive fan noise, reduced A/C performance, and poor fuel economy. The Caliso 22321 is a reliable, cost-effective solution for restoring OEM-level cooling fan operation on applicable vehicles.
