If the noise goes away when belt dressing is applied it would appear it is a belt issue. Belt dressing does not always fix a belt noise paticularly if its not adjusted to proper tension or if a idler pulley bearing is worn causing a slight misalignment issue.
BELT DRESSING IS A JOKE, ITS LIKE DIET PILLS. REPL ALL BELTS WITH NEW NOW THAT THEY ARE CONTAMINATED AND YOUR PROB WILL GO AWAY
