5.9L phantom coolant leak

I've had my 1998 JGC 5.9L for a couple of years now and love it. However, it's had a recurring but intermittent problem nearly the entire time I've owned it. Basically, the coolant level mysteriously drops from time to time, primarily during or after long road trips. I had the system pressure-tested, which seemed to point to a faulty radiator cap. Unfortunately, the problem continued after I replaced the cap. Engine oil is coolant-free when I change it, and no puddles of coolant appear under the Jeep while it sits in my garage.

It seems obvious that hot coolant is escaping the system from some point while I'm driving. So, where's the leak?

Thanks in advance!

idk but i'm having about the same problem with my 96 GC. at the begining of the summer i noticed the AC wasn't working. took it to the dealer in early june and they charged the system. ran it for a while and it was fine. they parked it over night and by the morning it was totally empty agian. they couldn't figure out where it was coming from. so they recharged the system again with some dye in it. ran it for a full 24 hours flawlessly. been working just fine since and they didn't do a damn thing to it. i'm just waiting it to break again. oh well.
