Mystery squeal (93 850) 850

As long time listeners will know, I've had an issue with my 850 for a while. An annoying squeal when the car is cold, or when I turn on AC. If I push pressure on the tensioner, the noise diminishes/goes away.

So far I've:

replaced the belt
replaced the idler pulley and tensioner pulley
created several new swear words.


With the belt off, the pulleys all spin and don't make much noise.

Now with both of the new pulleys (tensioner and idle) and the longer serpentine belt, the squeal should be gone, right?

Nope. Still there.

I've seen a few videos online talking about alignment of the pulleys, so that is the next thing I'm going to check. Are they easy to adjust?

Does anyone have a serpentine belt they'd suggest? I saw a video talking about gatorback belts, but I'm not sure if they offer one for 850s.

T.I.A.
