Viscous Fan Clutch for Renault/Claas Ares, Celtis, Ergos, and Temis Series Tractors

Description

When your fan starts roaring constantly even when it’s cool outside, or worse yet, your engine starts running hot during heavy work, it’s time to look at that viscous fan clutch. This viscous clutch unit is suitable for Claas & Renault tractors and automatically adjusts fan speed based on actual temperature conditions. It’s the smart cooling system these European tractors were designed to have—when it’s working right, you’ll barely notice the fan, but when you need cooling power, it’s there.

What You’re Getting

• Temperature-controlled fan engagement that saves fuel and reduces noise when you don’t need full cooling
• Precisely calibrated system using temperature-sensitive silicone fluid that remains thin when cold, allowing the fan to slip, then thickens progressively as operating temperature rises
• Intelligent operation that can free up 10-15 horsepower during normal operation compared to a direct-drive fan
• Direct replacement for your original clutch with no modifications needed

Built for European Farm Work

This viscous clutch fits a wide range of Renault and Claas models including the compact Celtis series utility tractors, mid-range Ergos models, and the larger Ares 500 and 600 series row-crop machines. Whether you’re running a loader on a Celtis 446 or pulling heavy implements with an Ares 696 RZ, this clutch automatically adjusts cooling to match your workload and conditions.

Made to Last

The hermetically sealed construction maintains precise calibration for the life of the unit, with no adjustment or service required. The robust sealed construction prevents contamination that would alter the clutch’s carefully calibrated response, ensuring years of maintenance-free operation. It’s built to handle the temperature swings and demanding conditions these European tractors face in real farm work.

Installation Notes

Never store the unit on its side or upside down, as this can cause fluid migration that affects performance. The fan blades often transfer to the new clutch, so inspect them for cracks or damage. After installation, check cold operation—the fan should freewheel easily, and as the engine warms, you should hear and feel increased fan engagement. A properly working viscous clutch means quieter operation and better fuel economy.
