What to do with a broken tensioner bolt for the serpentine belt?

Описание: You know how it goes… “I have 30 minutes so I will change the serpentine belt”.
It goes down the hill when the tensioner bolt breaks 😵‍💫
So I had to get creative to change the serpentine belt that was in really bad shape. Talking it out with the breaking bar was not bad but putting the new one in was harder since it was not stretched.
It certainly required my son’s help when I was pushing the tensioner.
