I had the same thing when I R/R the alt. After some head scratchin' I went back underneath and tightened the belt some more and presto, noise gone. Give it a try. Cheers

Ditto! Just did the timing belt on my baby and had the same squeal show up about 2 days later, every time I started the car, and yes I used new belts. Crawled underneath, undid the plastic belly pan, retightened the belts to spec (according to Tech Pages on Timing Belt Install) and problem solved. No more squeal!

In my Nissan service manual it shows an adjuster for/on the Power steering pump, the alternator and idler pulley. There are deflection settings for used and new belts as well as limits which I believe are to establish replacement times. BTW all the adjusters are a proper bitch to get at. Good luck, if I can help further, let me know.
