Agree, waterpump. I have just gone thru my whole cooling system and replaced everything but the heater core. I didn't just throw money at it, I checked everything out and being as the Jeep has 215,xxx, I was having some overheating issues and did have some leaks. In fact I had to replace 4 out of the 5 freeze out plugs on the side of the block. But do some testing as blue96jeep said. Looking at it can be difficult to actually see it leaking but from where it is dripping I would go with the water pump too.

Looks like the pump to me also, but I would get in there with a good light and make sure. If it is coming from the weep hole in the bottom of the waterpump it won't last much longer. It would be best to swap it out before it goes out and leaves you stranded with an overheated engine.
