Description

A fan tension roller is a critical drive component that maintains constant tension on the fan belt within a heavy commercial vehicle's cooling system. By sitting between the crankshaft and fan pulleys, it prevents belt slip and dampens vibrations, ensuring the cooling fan operates at the required speed to dissipate engine heat effectively.

This component is specifically designed for Mercedes-Benz vehicles, including the ACTROS MP4 / MP5, AROC S, and ANTOS series. It is engineered to work seamlessly with OM 471 LA engines, providing reliable performance in demanding heavy-duty environments. This part ensures the fan belt remains properly seated on the pulleys throughout the engine's operating cycle.

For optimal engine cooling performance, technicians should inspect the tensioner roller during routine maintenance. Signs of wear include increased humming noises or rising engine temperatures. When replacing, ensure the pulley dimensions and profile match the original equipment to prevent premature belt wear or slipping.

Consult your authorized distributor to check the compatibility list.
