Heavy-Duty Viscous Fan Drive for Agricultural Tractors SKU: QT58319

When your viscous fan clutch fails, you face two bad scenarios—either your fan runs constantly, robbing fuel and power, or it won't engage when temperatures rise, risking costly engine damage. This heavy-duty viscous fan drive restores intelligent temperature control to your cooling system, automatically adjusting fan speed based on actual engine conditions.

Why Professional-Grade Matters

• Temperature-responsive fluid coupling provides precise cooling control without manual adjustment
• Sealed design prevents contamination and fluid loss that destroys clutch calibration
• Heavy-duty bearings handle the constant engagement cycles of demanding farm work
• Built for continuous operation in dusty, high-vibration agricultural environments

A properly functioning viscous fan clutch saves 5-10 horsepower during normal operation while ensuring full cooling capacity when you need it most. Trust S&H Parts for reliable cooling system solutions—we've been keeping farm equipment running since 1969.
