Sad 3.5L front end belt noise for 1 minute when below 20*degrees outside!...

Anyone ever have this problem before?, It only happenes when it like below 20 degrees outside, and only does for about a minute or so. I have brand new belts(both main drive belt, and A/C), I wonder If I have to re-adjust my belts again, since I put in new belts, they do stretch out after a while. Anyone know about measuring belt deflection for precisely doing it rite with measurement numbers?. I do have a spare idler pulley for both belts that have 30,000 miles on them, while the ones on my car have about 150,000 miles, the only reason I put these back on where because They seemed pretty good still, never had a problem with them on my other motor(3.2L), they spun super smooth, w/ no noise when I checked, can this be that t hey are on their way out?, or...?.
(Note: when this happens and Im in the car, if I turn the steering either left or rite while in park, the noise gets louder, going either way(but my steering is still sooooooOoO smooth) So I think it cant be a powersteering issue, or anything, pulley looked lined up, I triple checked them before I put everything back together when I installed them. Can this be because of the pulley bearings?, belt deflection?(can belt more deflection loose H.P.?). I was also thinking about emptying my resivoir and powersteering system's old fluid out, and refilling with ATF+4, as it states to do so(NOTHING ELSE PERIOD!) in the FSM!. Anyone want to chime in this for me pleasssse?, I have saturday to work on this, and want to get as much info as I can on this problem!, Thanks Very much Guys!, ;)

What does it sound like. If it a growl, there is nothing you can do about it really. There was a TSB about it but it was jsut to tighten the belts to the right tension using their special tool and then it comes back a week or so later anyway. I've jsut learned to live with it.

Its a loud eRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRr rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rr........then away she goes (i know of the groal that you speak of, and have dealt with that no matter what, but this other noise is just driving me nuttttzzzzzzzzzzzzzzzzzzzzzzzzzzzzz, and its not the heat shields either. type of noise only for a minute or so, I even pop up to hood to hear it, and it sounds like a pulley, or the steering pump, or the belt loosened up a little, then goes away!,

thanks mopar/muscle for your quick reply!, ;)

Sounds like possibly the power steering pump. My cavalier used to do that when the rack was gone and I was low on fluid. It would do it sometimes when it was cold even if the fluid level was ok. I really can't say for certain what was causing it though because I worked on that PS system so many times I don't remember which solution fixed which problem. It may have been the pump or the rack, I can't say. It's possible though with it being cold the viscosity of the fluid is a little higher and the pump is struggling to pump it. I have had a constant whine since it's been cold and it sounds very much like the other constant noise I had when the fluid would run out in the cavalier. My fluid level is fine though so it's been puzzling me as to what it is. Good luck tracking it down dude!

my bets on the belt idler pulley, one of them anyway. My caravan did that and my trep started to until I changed the a/c idler pulley. No more noise.

I bet the idler pulley too. My serpentine belt started making noises after 95,000km's or so, and I was worried it was the pulley.......but I changed the belt and the noise went away

one thing you have to remember,, the cold and rubber dont mix the belts are stiff,, and warm quickly hence the noise goes away, the belts on my trep were always noisy when cold
