Ok, I just pulled off the belt, and, being nervous about running the engine with it disengaged I simply spun that top tensioner (the one with the spring) and I could tell easily that it was kind of rough when I spun it. Kind of like tiny bb marbles in there spinning around. I'm thinking this is it. What do you call the part, I tried looking up at autozone's website, but I'm unsure what it is callled. Just tensioner?
