Leaking Coolant

I have a 88 4.3 and it started leaking coolant it got really bad and was a non stop drip It looked like it was comming from the lower radiator hose and it was kinda rotted on the bottom. I replaced that but it still leaks somewhat. It seems to leak the night after I run it. It wont leak right after usually but Ill notice a puddle in the morning. Sometimes if I just start it up and back it down the driveway and park it it will leak a little bit to. I have the hose on tight and it doesent leak as much as it did with the old hose on.

Take a look at the weap hole on the water pump.
They leak sometimes hot or cold or luke warm or when ever they want to depending on where it stops.
Also shake the fan blades and see if the water pump is lose.
If all else fails run a pressure test on it.
