Four Seasons Standard Thermal Engine Cooling Fan Clutch

The Four Seasons Standard Thermal Engine Cooling Fan Clutch line gives you a direct-fit replacement thermal fan clutch (also called a cooling fan clutch or fan drive clutch) for gasoline and diesel engines. A thermal fan clutch uses a temperature-sensitive coupling to control how hard the engine fan works. It engages to pull more air through the radiator when the engine is hot. It disengages when the engine is at normal operating temperature.

Key Features:

• Temperature-responsive operation: The clutch engages for airflow when the engine runs hot. It disengages once the engine reaches its optimal temperature, which reduces fan drag and parasitic power loss and supports fuel efficiency.
• Built by application: Each clutch is designed and tested for its specific application, with OE-style fit, performance and appearance.
• Durable construction: Steel and aluminum components are built to withstand high underhood temperatures and demanding operating conditions.
• Precision machined: Machined components help the clutch install out of the box and run reliably.
• Multiple duty and rotation options: The line includes standard-duty, heavy-duty and severe-duty thermal clutches. It also includes standard-rotation and reverse-rotation designs, so you can match the clutch to your original equipment.

A failing fan clutch can cause overheating at idle or in traffic, excessive fan noise or poor air conditioning performance. Replacing it, often along with a water pump job, helps restore proper engine cooling. Four Seasons has decades of experience in engine cooling and climate control. Select the correct variant for your application to get the proper rotation, duty rating and mounting configuration.
