Hey guys. For some reason, i need to change my altenator belt on my car about every 3 months. I just changed it again. After about 2 months of driving, i have to tighten it. Then about a month later, it cannot be tightened anymore, cause its as far as it can go. What can be the problem here? Cheap belt? I am trying a goodyear gaterback belt ro see if it will last longer Or Could it be the harmonic balancer off or something? or maybe the waterpump pulley warn? My altenator is only 9 months old, and it did the same thing with the old one. Any suggestions?
