Question about 2001 Jeep Grand Cherokee
Check your water pump for signs of seepage. Do this with no pressure in the system and cap off. Sometimes in the beginning stages of failure pressurizing the system will drive the seal against the shaft and actually hide the leak. I have seen very small cracks in cylinder heads, especially between the valves that won't show up on a pressure test 'till they get worse. Check the plugs for any coloring from antifreeze.
You are going in the right direction so far, but need to go over everything sometimes a few times before a small leak is found. Keep an eye out for dried or semi-dried stains, especially around the perimeter of the head /block parting line...sometimes small leaks will only leave a slight stain, often white or antifreeze colored powder residue.
Hate to say it, but sometimes when you can't find it, just put some block sealer in there and see if it corrects the problem.I'm a professional but sometimes just doing that saves a big headache for a small problem.

Your letter is very confusing. You say " PRIOR TO REPAIR ANTIFREEZE HAD LEAKED BUT SHOWED NO SIGNS OF LEAKAGE" either it leaked or it didnt? I would say it needs to be checked by a repair shop. Tell them the problem, and history. They will need pressure test it, and also recommend a block check to test for exh gases in the cooling system. Be sure they pressure test it hot and cold.
