My serpentine belt keeps breaking (shredding). I've changed the Tensioner Pulley but I'm on my fourth belt. I notice my crank shaft pulley is moving up and down while running. Should my crank shaft pulley run true and smooth or is the movement from the harmonic balancer. What can be causing my belts to break?
have the same problem?
