coolant leak...

First off let me say that I am by no means a car expert. So can anyone help me out with this? I have a 96 Jeep 4.0 Cherkokee, 121000mi. The other day it was starting to overheat. I pulled over and noticed it was leaking coolant everwhere. I pulled over and refilled it. I figured it was the inner radiator hose. I drove home fine after that. I went out of town and didnt drive it for a day. Then the next day I drove a short distance around town and it was fine. I ignored it. I then drove it to work the following day (15 miles) and on the way home the problem happened again..coolant everywhere. I looked this time and the hoses seem to be fine. I cant figure out where its leaking from. I need some advice before I take it in. What should i look for. thanks.

Not a lot to go by but one of the most common leak spots on a 4.0 is the weep hole on the water pump see if there is a residue trail on the lower radiator hose leading to the water pump if it is the usual case it has been going on in small amounts and leaves stains marks.

Thanks Jeepfixitman! that was it. I replaced the water pump and all is good...for now.
