exactly how do i relieve the tension on my 93 buick lesabre serpentine belt to replace the alternator?

quaddriver

you dont need the special tool for this car, just use a 3/8" drive breaker bar and insert into the 'square' on the tensioning arm. 2 minute job tops.

MagicRat

If you don't have a 'square' on the arm, you can use a socket to rotate the bolt that holds the idler pully to the adjuster arm. This will rotate the entire arm, and relieve the slack on the belt.
