Best Answer

On my 90 VW Passat there are a total of 4 bolts that hold the alternator in place. Two at the top left are associated with the slotted metal bar that is used to slide the alternator back and forth to slip off the belt. The other two at the bottom (right and left) of the alternator are what you need to loosen to allow the alternator to pivot back and forth along the slotted bar. Loosen the top bolt first then the remaining two at the bottom to release the tension. You may need to use minor (hand) force to pivot the alternator then slip off the belt. Note you will need some long box mm wrench's to reach the bottom bolts. Remember also if you end up removing or changing your alternator that you disconnect the negative on your battery first.

How do you replace the alternator on a 1995 Toyota Celica ST?

AnswerThere are three bolts involved. The top bolt located closest to the engine is your Pivot bolt. Loosen that bolt so the alternator will pivot downward when you unlock it. Speaking of unlocking, there is another bolt located on the bottom of the alternator, loosen and remove this bolt. Finally, on the front of the alternator there is a tension adjustment bolt. Loosen that until the belt clears the pulley so that you can remove it. You don't have to remove the tension bolt, just loosen it. Once the belt is removed make sure to disconnect any wire/plugs, etc from the alternator, remove the pivot bolt and viola! Installation is the reversal.
