Truck Repair: 1994 Ford F150 4x4 Radiator Fluid, ford f150 4x4, radiator fluid

Question
I have a 1994 Ford F150 4x4 with a 351 ci engine.  I am getting radiator fluid under my truck when it sits for more than a day or 2.  Not everyday if I am using it.  I replaced the water pump about 3-4 months ago.  I have checked it and the water is coming from somewhere mid-engine from what I can tell.  It drips from above oil pan onto cross member and then onto ground.  Doesn't look like it is coming from head gasket are as I can see most of it from above and it is dry. Could it be a soft plug on the side of the engine that I can't see?  Any ideas?

Answer
Hi Brian,
That is what I would suspect.
If you get a small mirror, and a flashlight, and have the truck in a dark area, you can look at some places that are hard to see otherwise.
When looking out in the bright sunlight, it is hard to see some of those places.
