Four Seasons Standard Rotation Thermal Fan Clutch

The Four Seasons Standard Rotation Thermal Fan Clutch is an engine cooling fan clutch, also called a thermostatic fan clutch or radiator fan clutch. It controls how fast the engine cooling fan turns, based on the temperature of the air passing through the radiator. Your engine gets the airflow it needs to stay cool, and it wastes less power when it doesn't need that airflow.

Key Features:

• Thermal-sensing operation: A temperature-sensitive mechanism engages the fan more firmly when the engine runs hot and lets it slip when the engine is cool.
• Standard rotation design: Built for applications that use standard (clockwise, as viewed from the front) fan rotation.
• Reduced engine load: Disengaging the fan when full airflow isn't needed helps cut fan noise and parasitic power loss.
• Better cooling and warm-up: The clutch helps the engine warm up faster and keeps operating temperatures steady in demanding conditions such as towing, hauling, and stop-and-go traffic.
• Quality construction: Four Seasons is a well-known name in engine cooling and climate control parts. It designs its fan clutches to meet or exceed OE performance expectations.

A worn fan clutch can cause overheating, excessive fan noise, or poor A/C performance at idle. Replacing it restores proper cooling-fan control and helps protect the engine from heat-related damage. Each part number in this product line is matched to specific application requirements.
