I have an interesting issue. If you're looking at the water pump housing on the passenger side of the engine, there are 2 mounting bolts, and in between those 2 bolts, recessed in a little, is another hole for another bolt. I missed this when assembling the engine, and now its leaking coolant when trying to fill the system. I can't for the life of me remember taking a bolt out of that hole, and I don't have a bolt that seems to fit. I have tried 5/16 of various lengths and it just slops around in the hole. 3/8 seems to be too big. Any ideas?
Any help appreciated, thanks!

Big block housings have 6 bolts--3 on each side.
They are all the same thread size.
These holes go into the water jacket, so you will never seal it without the bolt in there...

That hole is where the water temp sensor screws in.
Then a wire attaches to make your temp guage work

None of those 6 holes go into the water jacket , the top top are thru holes and the bottom 4 are blind .
