Fixing a squeaky alternator typically involves a few simple steps. First, inspect the belt for wear and tear; if it's damaged, replace it. Next, tighten the belt tensioner as a loose belt can cause squeaking. If the noise persists, check for pulley misalignment or lubrication issues and address as necessary. Finally, use a spray lubricant on the bearings if safe and accessible. If these actions don’t work, you may need professional assistance.
