Is there a way to know if it is bad? I replaced my multi-v belt and it keeps on slipping off. I notice that the fan pully (harmonic balancer) is lose. Is there a way to tighten it?
The harmonic balancer is made up of steel and rubber (dampening material). In time the rubber part wears out causing the pulley to slip off the end of the balancer. Make sure all of your pulleys are in perfect alignment. If the balancer is loose it should be replaced - it cannot be tightened.
