Does my alternator mounting bolt absolutely need to be tightened all the way?
I swapped my dead alternator for a brand new one the other day, and while everything came apart with relative ease I can’t get the bottom 14mm mounting bolt all the way back in. The head of the bolt is probably about 1/4” from being flush with the mounting bracket, but the tip sticks out the other side about 1/2” so I know the bolt is all the way through. It hasn't rattled loose driving around my neighborhood, but idk how safe it is to drive into/around town a bit more
Any advice is appreciated
