How to take the serpentine belt off of a Buick?

I have taken them off other cars but can't seem to be able to find how the idler releases. This is a 1998 Buick Lesabre with a 3.8 V6. Also what's up with the bolt on the idler I can't get a metric or standard wrench to fit on it. What I am trying to do is change to altenator.



Thank In Advance

15mm socket on a breaker bar or long ratchet placed on the idler pully bolt.

if it is a spring loaded ideler, find the square hole in the aluminum arm and insert a 3/8 or 1/2 inch drive ratchet, which ever is required, then pull the tension awawy from the belt, don;t have to remove the tesioner.
i own a repair shop,and the process is just about the same as a Chevy except you get on the other bolt and pull to release the tension off of it,it basically works the same way though,you might have to loosen the one bolt but don't back it out more than one turn,but you should just be able to lift upwards on it,and release the tension on it,good luck with it ,i hope this helps.
Its the old imperial system that america's still using

caddilacs, buicks, chevys still use the ******* ancient measuring system.
