Typical symptoms include high-pitched squealing noises during engine startup or idling, visible wobbling of the pulley while the engine is running, and uneven wear on the fan belt edges. If you notice these, immediate replacement of CUM5255204 is required to avoid belt breakage.
While technically possible, it is highly recommended to replace the entire CUM5255204 Fan Idler Pulley assembly. Often the pulley groove itself is worn, and a new assembly ensures the dynamic balance is maintained, preventing future vibrations that could damage the water pump or alternator.
