That's what happened to mine. I put the new belt on and couldn't get the tensioner to pull it up before running out of threads. That is the stupidest tensioner design I think I have ever seen. It's a piece of rubber you wind up, so eventually, it takes a set and loses tension like an old stretched out rubber band. Everybody else just uses a spring and they never fail. I already had the whole front of the engine back together except the fan clutch, fan and shroud when I found mine was shot, so basically had to take it all back apart. Totally wasted a couple of hours and four days waiting on parts. And again, this is a car with less than 165,000 miles.
