332.03.0006 VOLVO Tension Roller, Fan Compatible

The heavy-duty tension roller plays a vital role in maintaining the precise tension of the fan belt within the cooling system. By regulating the belt path and preventing slippage, this component ensures that the cooling fan operates at optimal speeds, even under high thermal loads in heavy commercial vehicles.

332.03.0006 is the OE-equivalent of the VOLVO 20491753S, 21145261S, and 21155561S tension roller used in VOLVO heavy-duty vehicles. This precise engineering ensures that the part meets strict dimensional requirements for seamless integration into the engine cooling assembly.

Workshop technicians should inspect this component during routine maintenance of the cooling system to prevent belt wear or loss of tension. It is essential to check for smooth rotation and ensure that the bearing remains free from excessive noise or vibration during operation to maintain vehicle uptime and reliability.
