Caliso 22171 Thermal Engine Cooling Fan Clutch

The Caliso 22171 is a thermal engine cooling fan clutch engineered to restore proper cooling system performance. This direct-fit replacement fan clutch uses a thermostatic bimetallic spring to automatically regulate fan speed based on engine temperature — increasing airflow when the engine runs hot and disengaging at cruising speeds to reduce parasitic drag and improve fuel efficiency.

Key Features:

• Thermal (viscous) operation automatically modulates fan engagement based on underhood temperature
• Designed to meet or exceed OEM specifications for precise, reliable fit
• Includes fan mounting hardware for a complete installation
• High-load internal bearings for improved durability and wear resistance
• CNC-machined mounting surfaces ensure proper sealing and assured fitment with mating components
• Staked shaft end design prevents anti-rotation for long-term reliability
