Anybody replaced that exchange unit or repaired leek on passenger side right at the floor,I have slow leek and am curious whats involved. It is right where the tube comes through the fire wall.
I've read the procedure for that in the Hanes manual once, it involves pretty much taking out the whole dash to get to it. Sounds like alot of fun. If its leaking at the inlet/outlet tubes (likely from a pinhole), chances are you'll have to replace the exchanger, I doubt it can be patched up with any amount of success.
