Caliso 22411 Heavy Duty Thermal Engine Cooling Fan Clutch

The Caliso 22411 is a heavy duty thermal engine cooling fan clutch engineered to maintain proper engine operating temperature by automatically regulating cooling fan engagement. The thermal fan clutch monitors engine heat and engages the cooling fan as temperatures rise, then partially disengages when the engine reaches normal operating temperature — reducing parasitic drag, minimizing noise, and improving fuel efficiency.

Key Features:

• Heavy Duty Thermal Design: Locks up 70–80% of shaft speed when engaged, making it suitable for vehicles with higher airflow demands and fan blades with a pitch of 2½ inches or greater
• Temperature-Responsive Operation: Thermostatic bimetal spring on the faceplate automatically modulates fan speed in response to engine temperature changes
• OEM-Equivalent Fit: Designed to match the performance, fit, and appearance of the original equipment fan clutch it replaces
• Cross-Reference Numbers: Compatible with part numbers including Hayden 6631, Toyota 16210-31030, 16210-0P020, 16210-31040, and 16210-31050
• Durable Construction: Built to withstand the rigors of daily driving and meet or exceed original equipment specifications

The Caliso 22411 heavy duty thermal fan clutch is a direct-replacement part designed for straightforward installation. Professional installation is recommended to ensure proper torque and safe operation.
