After reading the post by MFSchmit it got me to thinking about my own truck. Im rapidly approaching 100K and it's time to do the Coolant and pump and belt. /Tensioner. Some said that the bearing in the tensioner wheel could be replaced ok I have a grip on that but what about the tensioner itself? Is there something that can go bad except the bearing in the wheel or is the tensioner itself a ware item. If so how would you check for ware? Or just replace the whole thing after all its got 100K on it. I'd kind of like to know before I tear it all down and dont have all the parts from Geno's
