Fan Drive / Viscous Clutch for OM904 Euro 3
Detroit Diesel

This viscous drive or fan clutch is engineered to regulate engine cooling by engaging or disengaging the radiator fan based on temperature cues. With an outer diameter of about 203 mm and a length of roughly 135 mm, it seamlessly connects to the fan assembly, providing variable fan speed control. Its viscous mechanism ensures that the fan operates only when needed, reducing unnecessary power draw and noise while maximizing cooling efficiency during high-temperature conditions. The clutch's design promotes consistent engine temperature management, which is essential for heavy-duty applications where thermal stability directly affects performance and engine life. Durability and precise operation are key, especially in extreme working environments.
