Viscous Fan Clutch, Temperature-Sensing SKU: QT43187

This viscous fan clutch adjusts radiator fan engagement based on temperature, ensuring efficient cooling when needed and reducing engine load when demand is low. Replacing a worn clutch restores proper cooling control and helps prevent overheating.

Built with a sealed fluid coupling and thermal sensing element, it’s designed to resist leaks, vibration, and heat. The direct-fit design makes installation straightforward in standard fan drive systems.

• Thermostatic viscous clutch for automatic fan control
• Engages at higher temperatures and disengages under light load
• Sealed housing protects against leaks and contaminants
• Durable construction for long service life

Installation Tip: Align the clutch with the drive hub, torque bolts evenly, and reinstall fan blades in their original position. Run the engine to operating temperature to confirm proper engagement.

A reliable replacement that balances cooling performance and engine efficiency in daily operation.
