There could be several reasons, Radiator, Hoses, Head cylinder Waterpump. One of the common problems found with some of the newer 4.0s is the ones with the head casting of 0331. They are known to crack in the middle of the head under the oil filler cap. Check to see if you have any water in the oil. It could be a very small amount, as I dont know how much coolant your loosing. Check for leaks under the Jeep, where they are can also help to find out where the leak is comming from. One of the best ways to help find a leak is to do a pressure check on the radiator and watch for leaking. I hope this helps you out.
