I installed new belts on my car and tried to tension them with "the tool" and I found the results to vary every time I put it on. I guess the main question is where should I place the foot of the toll that moves the needle? Should it be on top of a tooth or between two teeth? I know to not twist the tool and all that but I just don't know where to place it to get the proper results.

Hey Guys;
The round tension roller should indeed be in the valley of a pair of teeth. You can gently slip the gauge side to side and feel when you drop into one before you completely lock the drop-paddle in place. The gauge should be placed in the longest run of open belt you can find. That means upside down between the idler roller and cam sprocket for the cam belt. The paddles go on the smooth backside of the belt.
You DO INDEED want to move the gauge around a bit to settle it in place before taking a reading. I flip and roll it with my fingers a few times (this results in a slight twisting of the belt). You will note that 99% of the time the reading will decrease if you do this, and this likely is the cause of your meandering outcomes. Then reset the tell-tale needle and remove the tool for gathering your final numbers.

Yeah, but if the tool is not in the same spot you readings are going to change. When I did my first set of belts about 10 yrs ago I used the tool never again. In fact when I was at Taz's I couldn't even remember how to use it. The tool measures the tension at the length of tool if you're not in the exact same spot every time your reading will vary, it's kind of unnerving. At least this is my observation.
