Four Seasons 36966 Thermal Engine Cooling Fan Clutch

The Four Seasons 36966 is a standard rotation thermal fan clutch designed to regulate engine cooling fan operation. This thermal fan clutch automatically engages and disengages the cooling fan based on engine temperature, improving fuel efficiency and reducing noise during normal operation.

Key Features:

• Standard rotation thermal design for reliable temperature-activated operation
• Standard duty construction suitable for everyday driving conditions
• 5.85-inch diameter aluminum housing
• Flange mounting design with 4 bolt holes for secure installation
• Raw aluminum finish provides durability and heat dissipation
• Engineered and tested to provide years of trouble-free operation

This thermal fan clutch helps maintain optimal engine operating temperature by controlling when the cooling fan spins at full speed. When the engine is cold, the clutch allows the fan to freewheel, reducing parasitic drag and fan noise. As engine temperature rises, the thermal mechanism engages the clutch to spin the fan at full speed for maximum cooling. Four Seasons backs this fan clutch with a 12-month or 12,000-mile warranty against defects in materials and workmanship.
