 Correct, this thread is NOT about tensioning the timing belt, it's about tightening the nut to securely lock the tensioner in place after the tension has been set.

If the tension was incorrectly set by turning the tensioner clockwise, then the tensioner will tend to back-off in service. That doesn't mean it 'will' back off, just that it's loaded in a way that 'leans' in the direction of backing off. In that case, the Nyloc has a more difficult job ahead of it. If the tensioner does back-off, the root cause will be the incorrect procedure, not a failure to hold on the part of the nut.

If the tension was correctly set by turning the tensioner COUNTER-CLOCKWISE (as viewed from the front of the engine), then the tensioner tends to hold it's setting, and the nut's job is less demanding.

While there is nothing wrong with using a nut and a jam jut, if the tension is set correctly, then installing a new, full depth Nyloc nut each time will suffice.
