Four Seasons Heavy-Duty Thermal Fan Clutch

The Four Seasons Heavy-Duty Thermal Fan Clutch is an engine cooling fan clutch, also called a thermostatic fan clutch or radiator fan clutch. It controls how the engine cooling fan engages and disengages, so it supplies airflow across the radiator when the engine needs it.

Key Features:

• Thermal, temperature-sensitive design. The clutch engages the fan as under-hood temperatures rise and releases it when cooling demand drops.
• Heavy-duty construction for demanding applications such as towing, hauling, and extended idling.
• Helps cooling performance by moving more air when the engine is hot.
• Lets the fan run more freely when cooling demand is low. This can reduce engine load and fan noise.
• Built as a direct replacement for the original fan clutch.

Four Seasons is a well-known name in engine cooling and climate control components. Each clutch in this product line is designed to restore reliable cooling-fan operation and to help prevent overheating caused by a worn or failed fan clutch.
