Ok, I was doing what you said and while I was tightening the bolts, evenly I might add, the top part of the water pump BROKE OFF!!! The pump is still stuck in there. I'm trying to tighten the bottom bolt, but it's really hard for me to fit my ratchet in there because it is bumping into the bottom part of the water pump. I'm trying to tighten it as much as I can fit my ratchet in there but to no avail. Now I'm going to home depot and getting a crowbar. What do you think?
