332.02.0004 MAN Compatible Fan Tension Roller

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, ensuring the belt runs on pulleys without slipping. It is positioned at the front of the engine to compensate for belt elongation over time, dampen vibrations, and preserve the correct wrap angle. This component is essential for preventing belt slip, humming noises, and rising engine temperatures.

This specific component is compatible with various MAN models, including the Lion's City (A 22), Lion's Coach (C 310, C 320, C 360, C 400, C 440, C 430, 440, L 505, L 430, L 400, L 440, C 480, 480, 400), and Lion's Regio (350, L 440, L 430, L 390, L 350, L 330, C 430, C 390, C 350, C 310, 320, C 320, 360, C 400). It also fits MAN Lion's Classic (270 to 360), HOCL series (18.350 to 18.311), ND (323/363), SL II (SL 353/SL 363), SÜ (SÜ series), NL (NL series), and NG (NG series) models. It is suitable for engines such as the D2676.

When performing installation or maintenance, technicians should verify the pulley diameter and width against the removed part to ensure a precise fit. It is vital to check that the mounting dimensions—including center bolt diameter and thread pitch—match the original specifications exactly to avoid centering errors. Proper installation ensures the cooling system operates within its designed parameters.

Consult your authorized distributor to check the compatibility list.
