Before removing all the belts get a spray bottle of Windex (glass cleaner) and with the engine running at idle spray each belt with the Windex. Spray it generously at each belt on the side riding in the pulley groove. If the noise goes away buy new belts. Note: the Windex will only stop the noise till it drys out. So the noise may return. Do not use belt dressing. Before installing new belts clean all the pulley grooves completely. Be careful of the moving belts, pulleys and fan blades.
