I just replaced my timing belt last month at 105k. I used the Courtesy Autoparts kit. I could not believe how loose my old belt was. I undid the nut for the tensioner and tensioner swung all the way out not realy putting any tension on the belt. It must have been streched pretty good.
On instalation I lined up the marks, let the spring hold tension on the belt then locked the tensioner in place. Then I pushed down on the belt and checked to make sure there was roughly 1/2" deflection which there seemed to be. So I think I am ok there. The one place I did screw up was the tensioner stud. once I got the whole thing back together I turned around and realized it was sitting on the bench behind me. I also realized that I hand torqed it instead of using a torque wrench. Will I be ok on that or am I going to have to open her back up and redo the tensioner stud once it warms up around here?
