I know what you're saying and it would make sense. And why would I want to have no AC? The lines were bent and broken in places so I took them out. I have another set I'm putting in. It's coming from behind the engine, not really where the AC line is at the fire wall. I was thinking it was the coolant pipes. I really need a diagram of under the plenum or on the back of the engine so I can make sure everything is ok.
