I know they are bigger than 1/4". I want to go buy a square end socket but not sure of the size. 7mm, 8mm?

Thanks...
 
Use Vise Grips and be done with it. Then, go to NAPA and purchase petcocks to give you the ability to drain the block.
 
I did that once on the driver side of the block; easy to get to. The passenger side is up and over the starter. I don't have very effeminate hands so there's an access problem there for me. :D
