Coolant system overheating

[BlackBetty]

Ok, so I bought a 1997 Chevy 1500 5.7. I can't seem to keep the water pump from leaking. The coolant sprays from the bolt holes on either side regardless of how much I torque it or seal it. I replaced the thermostat, and recently I put a new, heavy duty dual core radiator in it because the old one was clogged. Now it seems like it blows steam out from every where. I'm lost, I don't know where to even begin

After you have the water pump removed are you making sure the bolt holes are completely dry?
Are you putting sealant on the bolts before you install then?
Are you putting sealant on the water pump gasket?
Have you pressure tested the cooling system pressure/radiator cap?
