Viscous Fan Clutch for John Deere 3150-3350 and 6000 Series Tractors SKU: QT59577

When your viscous fan clutch fails, you face two serious problems - either a constantly roaring fan that steals 10-15 horsepower all day long, or a fan that won't engage when needed and lets your engine overheat during heavy work. This temperature-controlled replacement automatically engages the cooling fan only when engine heat rises, protecting your tractor while maximizing available power for field operations.

Why This Part Matters

• Automatically adjusts fan speed based on actual engine temperature
• Saves fuel and reduces noise by freewheeling during light loads or cool weather
• Sealed construction protects internal silicone fluid from contamination
• Progressive engagement prevents shock loads that damage belts and bearings

A failed clutch that's locked up constantly wastes fuel and power, while one that won't engage risks expensive engine damage. With over 55 years of cooling system expertise, S&H Parts can help you identify the right replacement for your specific John Deere model.
