Caliso 22409 Heavy Duty Thermal Fan Clutch

The Caliso 22409 is a heavy duty thermal fan clutch engineered as a direct-fit replacement for engine cooling systems. Thermal fan clutches regulate engine cooling fan speed based on temperature, engaging the fan fully under high-heat conditions and allowing it to freewheel when cooling demand is low — improving fuel efficiency, reducing noise, and extending belt and water pump life.

This unit features an all-aluminum body for efficient heat dissipation and a high-quality heavy duty bearing packed with high-temperature moly grease for long-lasting durability. CNC-machined mounting surfaces ensure precise fit and help prevent fluid leaks, while the improved shaft design provides greater strength and enhanced load capacity.

Key Features:

• Heavy duty thermal clutch design for reliable temperature-controlled fan operation
• All-aluminum body construction for efficient heat dissipation
• High-load bearing with high-temperature moly grease for extended service life
• CNC-machined, tapped, and drilled mounting surfaces for assured fitment
• Staked end for anti-rotation stability
• Smooth surfaces reduce stress risers and lower material stress during assembly
• Full surface contact on all interference fits
• Direct-fit replacement — no modifications required
