That's a pretty specific and certain diagnosis considering how many ways a Jeep can leak coolant

Just kidding, that's actually how my stock radiator died and is probably common. However, the OP already stated he has already installed a new radiator and is still getting a leak.

Make sure to check your fan and relay. Failure of these components could have caused extreme pressure making the radiator fail to begin with. All of those component failed on mine -- including the radiator -- a few years ago and has been fine every since I put new ones on.
This is a brand new radiator. And I have searched every where and still can not seem to find where it is leaking from but I do know for sure that it is on the passenger side and not running along the bumper

Ah, I didn't see he replaced the radiator already - even though it could be defected, too. With all those replacements, you would have certainly went ahead and bought new radiator hoses... Buy some dye and put a light on it, then.

You're sure it's antifeeze, right? If it's AC condensation, I'm gonna laugh you out of this thread.

The dye has special UV tint in it and when you shine a black light on it, you can trace exactly where it is coming from.

You can probably borrow a coolant pressure tester from a local parts place. I had a mysterious tiny wee leak and I found it with a pressure tester. You can pressurize the system without getting the engine hot and then you can look and listen for that leak.
