Nissan Repair: a/c (serpentine) belt, tension bolt, nissan sentra

Question
Hi,
I have a Nissan Sentra '01 in need of a new serpentine belt, and I'm confused as to how the pulley system works/how to install it. Please help, thanks :)

ps i've seen a similar question asked before and it seems to me like for the front belt to be replaced i'd have to remove the back belt, rather than vice versa? please help...thanks

Answer
Joe,

The tensioner pulley has a lock bolt in the center and a long bolt that does the tightening and loosening.  Break the center bolt loose and then let the tension off with the long bolt.  The power steering is a different issue where the pivot bolt has to be released as well as the tension bolt.  Then pivot the pump to get the belt off.
