Awe hell, I forgot about that pic.
That isn't my engine. It was just a random Google image I found ... only one I could find of the freeze plug the guy needed to see.
I'm not sure what tensioner that is but I will find out. Far as I know Gates, Dayco and Cloytes don't make it.
... I'm not even sure who's engine that is, so can't ask them.
Don't "think outside the box".
There is no box.
