On the later models I think you have to remove the AC belt?  Which has a
tensioning bolt; where as the alternator doesn't so you need to use a large
screwdriver or pry bar to tighten the belt.  There are two bolts that need
to be loosened on the alt: the bottom pivot bolt (the back side of the bolt
you'll need a long extension on you socket wrench) and the bolt on the
slide.  Removing the AC belt is a bit more complicated: two pivot bolts
(Allen), two slide bolts, and a tensioning bolt (and the plastic snap on
guard.)

Good luck

Loosen alternator , change the belt, tighten the alternator.

Sometimes the Bentley is just good bathroom reading material.
Nothing more.

BUT, just for the sake of curiosity.
Why would anyone need a service manual to change somehing as simple as a
belt???
