I have a 1996 Chevy K1500 Z71 pickup and it is leaking water from under the rocker pan any ideas on where the water is coming from. I noticed it leaking when I got home and you could put water in radiator and it would come out as you put it in. Let it set overnight to cool off when I started to see were water was coming from put water in radiator and was not leaking so I stated motor and then it started leaking again check the oil and it is nice and clean. Any suggestions on were it is coming from. Thanks Aaron

Check all of the hoses for cracks.

The radiator may have a tiny crack in it. As the coolant gets warm, it heats the radiator. When the radiator is heated, the material expands. This expansion will make the tiny crack even bigger, allowing the coolant to leak.
