How to troulbeshoot squeaking and squeeling around belts and pulleys? I have already changed the idler pulley and the tensioner pulley. I am not sure what else it could be.

IF it is the 3.0 motor. I would find a way to live with it.
I have one. Lol.

I believe there is an engineering flaw that causes the belt to ride and return causing a squeak. Replacing parts only seems to temporarily allieviate the noise.

I would suggest getting some valve grinding compound
and globbing/dabbing it on both sides of the belt at spaced out points. IF there is glazing it will remove it.
If the belt is older it may be the problem source itself should it quiet after the compound was applied.
