Thermostatic Viscous Fan Clutch SKU: QT41117

This viscous fan clutch regulates radiator fan speed based on engine temperature, engaging the fan under load and disengaging when cooling demand is low. A malfunctioning clutch can lead to overheating or unnecessary drag.

Constructed with sealed fluid coupling and internal thermostatic control, it endures vibration, temperature shifts, and engine bay stress. It’s engineered as a direct replacement clutch unit for ease of service.

• Thermostatic viscous clutch for radiator fan drive
• Automatically adjusts engagement per temperature variation
• Sealed construction to resist leaks and contamination
• Designed as a drop-in replacement for ease of fitting

Installation Tip: Align the clutch carefully with the drive hub, mount the fan blades exactly as original, torque bolts uniformly, and then test at high temperature to confirm proper engagement.

A dependable replacement unit that balances cooling performance and engine efficiency across operating conditions.
