broken bolt 1993 alternator tensioner to block thread size/depth
Anyone happen to know the thread size and depth of a b230 alternator tensioner bolt from a 1993 240? My bolt is broken. I drill it pretty much exactly on center and it wont come out. I don't want to bow up on the easy out and further for fear of breaking it and then having to drill out a super hardened easy out. So I feel like a helicoil is the way to go. I don't want to drill too far though and hit coolant.
