Squeaky pulley tricks?

I replaced the serpentine belt on my truck the other day but I am still having a squeak. Anybody have quick tricks for isolating which pulley it would be? Last for about 15 minutes when I started cold and then goes away.

I shoot WD40 on each pulley one at a time until it stops.

Grab a spray bottle of soapy water and mist the belt and see of the noise goes away or not first I have seen new belts squeak sometimes also. Next look for a pulley alignment issue. After that then play with isolating pulleys and what not.

So if it IS the new belt, then what....? Spray it with that belt antisqueak spray or something that is longer lasting? It is actually worse since I put the new belt on.

I actually did spray a few of the pulleys with WD40 tonight. Hadn't helped right away, but maybe after it sits and penetrates a little.

If it makes more noise sometimes then new belts are junk have run into it before

On a side note....since it seems to go away after it warms up, would that tend to point more towards the belt as well? Would a pulley squeak even go away typically?

Well I got my question answered. I sprayed some soapy water on it and it instantly went away. Looks like I will be redoing the belt again. LOL.

Make sure the pulleys all spin smooth and even. The tensioner could be coming apart or another pulley wobbling when spinning causing the squeak.

I replaced the belt tonight.....seems good so far. Sat for 5 hours and didn't squeal....in 50 degree weather. So we will see. If anything tensioner seems a little aged if anything on the belt change so I can change that if need be....
