In the diagram above, #8 is a stud that holds the tensioner to the water pump housing.
Just below where its located is a recess, show in the diagram, where a nut screws onto a stud that then holds the housing to the block.
I cant find this stud on any of the diagrams i look at. Pictures of the block dont show it, nor where it even goes.
The reason im asking?
Mine is snapped off, and i need to work out how deep is safe to drill.
