After upgrading my alternator to a 95 amp unit from a newer heavy-duty truck, I found that the older style V-belt setup wasn’t up to the task anymore. The belt would constantly slip and squeal and tightening them up would only temporally fix the problem. Eventually, the belt would break apart about every month or so. An upgrade to the belt system was in order. This article is to upgrade your Alternator V-Belt system for a GM V8.
