331.01.0015 Belt Tensioner, Fan — MERCEDES BENZ

The 331.01.0015 Belt Tensioner, Fan plays a critical role in maintaining the proper tension of the cooling system belt, ensuring stable operation of the fan and auxiliary components. This high-strength component is designed to withstand the rigorous vibrations and thermal cycles typical of heavy commercial vehicle environments.

This part serves as the OE-equivalent for the MERCEDES BENZ 457 200 19 70 and 460 200 09 70 models used in the cooling system. It is also fully compatible with DAYCO APV1096 specifications. The 331.01.0015 is the OE equivalent of the DAYCO APV1096 belt tensioner used in MERCEDES BENZ heavy commercial vehicles.

Workshop technicians should ensure that the belt path is clear and that the mounting surface is free of debris before installation. Proper alignment is essential to prevent premature wear of the belt or bearing failure. Regular inspections of the tensioning mechanism are recommended during standard service intervals to maintain optimal engine cooling performance.

Using high-grade materials ensures that this component maintains its structural integrity under heavy-duty load conditions, preventing unexpected downtime due to belt slippage or tension loss.
