This sounds like water wetter is doing the job: making the  coolant more
efficient at transferring heat out of the engine

I don't know about Jeeps. Is there a sneak path for coolant to flow between the
radiator and the engine? I would be very surprised that such a path would be
large enough to defeat the thermostat with just slightly better coolant. Is it
possible that your thermostat is sticking open?
