To fix a squealing alternator, first check the belt tension. A loose belt can cause squealing; tighten or replace it if necessary. Next, inspect the belt for wear and replace it if it's cracked or glazed. Use a belt dressing spray to condition the belt temporarily. If the squeal persists, check the alternator bearings or pulley; these may require replacement by a professional.
