Thermostatic Viscous Fan Clutch for Ford 40 Series and New Holland TS115 Tractors SKU: QT41117

When your viscous fan clutch fails, the symptoms are immediate—overheating under load when the fan won't engage, or constant fan roar and reduced power when it stays locked. This thermostatic clutch restores proper fan control, automatically engaging when cooling demand increases and disengaging during lighter operation.

Why Temperature Control Matters

• Sealed fluid coupling design prevents internal leakage that causes premature failure
• Internal thermostatic control responds accurately to engine bay temperatures
• Engineered for drop-in replacement without modification to mounting points
• Built to handle continuous vibration and thermal cycling in demanding applications

When your old clutch starts freewheeling or locks up solid, this replacement unit brings your cooling system back to proper operation. Mount the fan blades exactly as original and test engagement at operating temperature to confirm proper function.
