Wonderful... now I can see why there wasn't a bolt in there.....
There must be a burr or thread problems inside the block itself. Snapped the new bolt off in the block putting it in.. and it couldn't have been with any more than 15lb ft.....
So I'm guessing the only option is to take off the grill, radiator, and fans and drill it out and retap?
