I have a lot of trouble with my AC belt since I switched to 134a. If routing around the WP would help with the squeal at all, I'm going to be all over that in the spring.

I would think if anything having the belt run across the 3 pulleys instead of 2 could make it squeal more, just because it decreases the surface area the belt touches on each pulley. ...
OE setup wraps belt 180° around Crank and AC pulleys.
That "Upgrade" using WP wraps AC clutch ~90° means less belt
to drive AC compressor. That is not a good thing.
The belt likely will fail sooner then OE setup.
Over tight a belt is bad as loose belt. Both can fail the belt. Likely worse because tight belt can fry WP Alt AC bearings. See my Cave, Serpent Belt
Has belt tension data etc.
Bad AC pulley bearing can make the belt fail.
Bad AC compressor can make the belt fail.
AC mount brackets problems can cause pulley misalignment...
Some Double pulley WP like have replace dead WP w/ a new pulley and WP. Double pulley keep store inventory low.
Many likely have engines was replace during recall/warranty work. Most engine like that are engines from GM that fits FWD cars and Fiero. They came compete so dealer does minimum work to replace engine. Dealer payout under recall/warranty work are fix pay under GM "flat rate." Most Recall TSB have Labor Rates dealers get. Some recall docs at http://www.fieronews.net/fusion/downloads.php
shows flat rate for Dealers.
