This tool is the Belt Tension Gauge #91107 made by Gates
Also here is the Service manual to proper belt tension and procedure it is #13

A belt will only come off if improperly installed, usually insufficient tension. Or the belt snaps. |
Some call it a Krikit. I did use one.
I had installed new belts last year and reinstalled the same ones after doing the water pump and fan clutch a few weeks ago.
I failed to recheck the belt tension after driving a few times.
I also remember one of the alternator belts not holding the same tension as the other one. I should of tightened the loose one up to spec and not worried about the other one being a little tighter. There are two pulleys on the alternator that allow two belts (same size) to drive or turn such pulley. You would think that you would only have to check the belt tension on one belt.
I guess it might be possible that belts with the same size dimensions are not created equal.
There are 2 specs provided by the FSM, one for reinstalling the same belt and one for installing a brand new belt.
I believe I should of used the spec for the new belt install.
I used the spec (belt tension range) for a previously installed or used belt.
Belt did not snap so I take it that it was loose and then jumped off. Failed to tension the belts properly I guess.
Will install tranny hoses, belts and add tranny fluid on Sunday and report back
