Caliso 22174 Heavy Duty Thermal Fan Clutch

The Caliso 22174 is a heavy-duty thermal fan clutch designed as a direct-fit replacement for trucks, SUVs, and commercial vehicles. The thermal fan clutch regulates engine cooling fan speed based on engine temperature, engaging the fan when cooling demand is high and allowing it to freewheel at lower temperatures to reduce parasitic drag and improve fuel efficiency.

Key Features:

• Heavy-duty construction built to meet or exceed OEM specifications for durability and longevity
• Thermostatic operation automatically modulates fan speed in response to engine heat for optimal cooling performance
• Direct-fit replacement for straightforward installation without modification
• Precision-sealed bearing helps prevent leakage and extends service life
• Silicone fluid chamber provides consistent engagement across a wide operating temperature range

The Caliso 22174 thermal fan clutch is an ideal solution for restoring proper engine cooling performance, reducing fan noise at highway speeds, and improving overall drivetrain efficiency.
