I doubt if its the original belt, but you never know? I purchased the vehicle with roughly 48K, so its a possibility bc I have never replaced it to date. Now I am no expert on serpentine belts, but there are no obvious cracks or gouges. When you say check for play in the tensioner, exactly how does one do that? Or should I say how much play, if any, should it have?? In the meantime, I'm gonna go ahead and replace the belt, its cheap enough and hopefully kills the noise.
