Video tutorial

This video shows how to identify and resolve the annoying noise coming from the alternator. If you hear a disturbing noise in the engine bay, specifically from the belt driving the alternator pulley, the issue may be with the alternator itself.

To eliminate the noise, either replace the entire alternator or simply replace its pulley. Use the correct spanner to loosen the auxiliary belt and remove it to better locate the source of the noise; in this case, the noise originates from the alternator pulley, which will make noise when moved.
