I recently found a puddle of coolant under my TJ. I traced the leak to one of the transmission cooler line fittings. But looking at it, the coolant seems to be coming from between the plastic housing and the flange part of the metal fitting, not the actual thread of the hose barb. I’ve been trying to think of a way to fix this, but I’m at a loss. Anyone have any suggestions? Or am I going to be replacing the whole radiator?
