Here is where I stand:
checked the coolant during warm up and after a 20 min drive - no bubbles in the filler neck of the radiator. I have V-Belts and am going to check the water pump for a 3rd time to make sure right pump. I am on my 2nd thermostat. I am also going to check actual coolant temp with a thermometer tomorrow. I'll let everyone know what I find. I am leaning toward a blocked passage in the head. The pervious owner never complained of overheating but the first day I owned the jeep, I found a 1/8" hole in the coolant reservoir and patched that day. Have had cooling problems since day one.
anyway, let you know what I find.
Brad.
