Caliso 22140 Heavy Duty Thermal Reverse Rotation Fan Clutch

The Caliso 22140 is a heavy duty thermal fan clutch engineered to meet or exceed OEM specifications. Featuring a CNC-machined aluminum body and reverse rotation design, this bolt-on fan clutch is built for demanding cooling applications where precision fitment and reliable performance are essential.

Thermal fan clutches operate by sensing underhood temperature through a bi-metal thermostatic coil. At low speeds or under high heat loads, the clutch fully engages the fan to maximize airflow through the radiator. At higher speeds or lower temperatures, it partially disengages, reducing unnecessary engine load and improving fuel efficiency.

Key Features:

• Heavy duty thermal design meets or exceeds OEM specifications
• Reverse rotation bolt-on fan clutch
• CNC machined to exact OE specifications for precise fit
• All-aluminum body for efficient heat dissipation and reduced weight
• High-quality, heavy duty bearing packed with high-temperature moly grease
• Direct bolt-on installation — no modifications required

The Caliso 22140 is a reliable replacement for worn or failed fan clutches, restoring proper cooling system function and protecting your engine from overheating.
