The radiator on these Jeeps has a plastic housing at the hose connection. The plastic part is known for cracking or forming small holes, which are not easily seen in the beginning, until things get worse from steam pressure. Just repaired one today. I'm trying to save the radiator by cold welding plastic on the inside of the radiator neck and on the outside to form a sandwich. Waiting for it to cure to test the results.

Same with my Jeep, and it's a 2000 Jeep Grand Cherokee 4.0L.

The radiators in the Jeeps are too small.
I had a Laredo with a 4.0 liter. I bought it from a friend. He told me it keeps overheating.
One day going through a canyon in California, going up it over heated and red lined. Blew the head gasket. My friend had changed the fan clutch, water pump, thermostat, hoses, fan blades-fan. Still was overheating.
He was off road one day and hit a jack rabbit. Took it to the dealer to fix it. They put a new radiator in it, the same type he had in it. But kept getting hot. When I was driving it thru the canyon and it red-lined and blew the head gasket, at least I was able to coast home.

I am wondering if you ever found the source of your coolant leak? I have the same issue.
