Skyward Automotive Products SK36729 Radiator Fan Clutch

The Skyward Automotive Products SK36729 is a thermostatic radiator fan clutch designed to regulate engine cooling fan speed based on temperature. This fan clutch automatically engages and disengages the cooling fan to maintain optimal engine temperature while reducing unnecessary drag on the engine when cooling demands are low.

Key Features:

• Temperature-activated engagement for efficient cooling performance
• Reduces parasitic horsepower loss by disengaging fan at lower temperatures
• Helps improve fuel economy during highway driving and cooler conditions
• Direct replacement design for simplified installation
• Durable construction for reliable long-term operation

This fan clutch mounts between the water pump and engine cooling fan blade assembly. When the engine reaches operating temperature, the thermostatic clutch engages to spin the fan at higher speeds, drawing air through the radiator. As temperatures decrease, the clutch partially disengages to reduce fan speed and mechanical load on the engine.
