I replaced my alternator this week and just loosened the pivot bolt at the bottom to re-tension the belt cause it was squealing...and when I tigtened the pivot bolt up again it wouldn't go tight again..just kinda snug. I assume I stripped the bolt or threads on the case of the alternator itself. Any suggestions on what to do. I will order a new bolt from the dealer tomorrow but would threadlock work? I don't want to but a new alternator.
