What would make water shoot from a hole on the engine block behind the water pump?
[Edit]

Answer

sounds like the weep hole , time for new water pump

Answer

It's not the waterpumb, the problem was the part the waterpump mounts to. It look like it might have been dropped or hit with a hard tool during installation. The hole is a broken edge of that part, making a broken seal so it needs to be welded or sodder to work correctly.

Answer

It could also be a block or head freeze out plug that is old or damaged. They are very inexpensive and fairly easy to install. To remove an old one, use a hammer and screwdriver and pick one edge and punch it in. Use a pair of pliers and pull it back out sideways or drill a hole through the center and use a dent puller slide and pull that way. To install a new one, find a socket that fits inside of it almost perfectly and as carefully as possible, tap the new one in as straight as you can. Clean the inner surface first with steel wool to remove any deposits and give the new one a good seal.
