The only reason i don't think it's a belt is because the lubrication i'm using is belt dressing.. I feel like that would take away squeaks to do with the belt
Also just putting this out there, I've used napa belt dressing on a belt that squeaked, and it made it 4 times louder and much more intense. A new belt fixed that issue, so the dressing didn't work in that situation at all.
