Serpiente belt squeak

[Firemn260]

So after I did all the timing chains and cassettes on my 2003 it is running great. I just got back from a 1250 mile round trip run to the Smokey mountains in Tennessee. I love this truck.
Right before I left I replace the belt, idler and tensioner pulley because it was making noise. It was all quiet until about a week ago and the squeak came back. I’m not talking about a chirp, it’s a loud constant noise that’s annoying the crap out of me. All the pulleys look to be in alinement and when I sprayed some water on it it goes away for a moment so that ruled out any bearings. It seems once the truck runs for a while it goes away but now that it’s getting colder it seems to last longer before it does.

I replace the belt with a Dayton and I’m wondering if it maybe is the wrong size?
Any of you run into this problem?

Dayton’s generally good, but you might try putting the old one back on and see if the noise changes. Use a good straightedge on the pulleys- eyeballing it isn’t really precise.
