I'm sure I'm not the only one that has had an issue. The way you adjust the belts on these cars (alt and ac) there is a bolt you loosen and then you put a wrench on a cogged piece which rotates on another cogged piece. Well mine were rounded off since its so thin and rusty over time. Has anyone changed there's to a bolt that presses against something to pull it tight or something else? Can you replace these with new pieces? Right now I've just pried against the accessory tight with a pry bar and tighten the adjustment bolt.
