Hi all. Recently developed a strange rhythmic noise coming from the serpentine belt/ pulley area. Almost sounds like a rubbing or creaking and it is in rhythm with the belt turning about a second apart. It sounds like it is coming from one of the pulleys and not the belt itself... I cannot tell if it is the idler pulley, the crankshaft pulley or waterpump etc .. Car runs fine and no CEL.. Would a bad crankshaft pulley show more symptoms then just a noise? Am getting it looked at soon just looking for some thoughts. It is not a belt squeal more like a rhythmic creak.. I will try to get a video clip up tomorrow.
