Caliso 22155 Thermal Fan Clutch Replacement

The Caliso 22155 is a thermal fan clutch designed as a direct replacement for belt-driven engine cooling fan systems. The thermal design uses a thermostatic mechanism to engage and disengage the cooling fan based on underhood temperature, delivering airflow precisely when the engine needs it most and reducing parasitic engine load when it does not.

Key Features:

• Temperature-controlled engagement — the thermostatic coil reads underhood heat and engages the fan when cooling demand is high
• Automatic disengagement at highway speeds or lower temperatures to reduce engine load and improve fuel efficiency
• Direct-fit replacement for worn or failed OE fan clutches in applicable belt-driven fan systems
• Cross-references to part numbers 215155, 2726, 36940, and A5587

A properly functioning fan clutch is critical to engine cooling system performance. A failed clutch can cause engine overheating at idle or low speeds, reduced A/C performance, excessive fan noise, and increased fuel consumption. The Caliso 22155 restores correct thermal fan operation and helps protect the engine from heat-related damage.
