331.02.0002 MAN Fan Belt Tensioner Equivalent

The fan belt tensioner is a critical mechanical component in the cooling system of heavy commercial vehicles that keeps the belt driving the fan at the correct tension. By applying constant pressure through a spring-loaded arm and bearing-mounted pulley, it prevents belt slippage and ensures the cooling fan operates at the required speed to regulate engine temperature.

This unit is specifically engineered for compatibility with MAN vehicles, including models such as the Lions City (A 35, A 37, A 66), Lions Classic, SL II (240, 280), and Lions Coach. It is also fitted to various MAN HOCL, NL, NM, and SÜ series trucks and buses equipped with D0836 or D2876 engines. This part ensures reliable performance across diverse heavy-duty applications.

For optimal engine health, technicians should inspect the tensioner during routine maintenance intervals. Signs of wear include unusual belt noise, vibration, or visible belt fraying. Ensuring the tensioner maintains stable pressure helps prevent overheating and extends the service life of the entire fan belt assembly.

Check the compatibility list to ensure exact fitment for your specific engine configuration.
