Temperature-Controlled Viscous Fan Clutch for Agricultural Equipment and Cooling Systems SKU: QT64969

A failed viscous fan clutch leaves you with two expensive problems—either a fan that runs constantly even when you don't need it, robbing 10-20 horsepower and burning extra fuel, or one that won't engage when temperatures climb, risking costly engine damage. This precision-engineered replacement restores intelligent, temperature-based fan control that automatically adjusts cooling power exactly when and where you need it.

Why Temperature-Controlled Cooling Matters

• Automatically engages only when temperatures rise, saving fuel and horsepower during light work
• Sealed silicone fluid system maintains precise calibration throughout service life
• Heavy-duty bearings and construction handle the constant speed variations and high rotational forces
• Progressive engagement prevents shock loads that destroy belts and water pump components

When your cooling fan is either locked up and roaring constantly or slipping when you need maximum cooling, this viscous clutch delivers the smart cooling control your equipment was designed to have.
