94 Intrepid 3.5L AC refrigerant leak

Discussion in 'General Motoring' started by NowItsWhatever, Aug 13, 2006.

  1. Using UV leak detector, I have discovered an AC refrigerant leak from the
    low side service valve fitting. Can just this part be replaced?

  2. Where is it leaking?

    Usually these parts are either the valve is welded to the aluminum AC line
    or there
    is a nub that is welded to the AC line that the service valve is screwed

    If it is leaking from the weld, you have to replace the line.

    If it is leaking from the valve - to - service line nub, you need to
    replace an O ring or washer or some such that is in there.

    If it is leaking THROUGH the valve - ie: the shrader valve in the
    service valve - then you need to replace the washer that is in the plastic
    cap that screws onto the valve to keep dirt out of it. The shrader valve
    that is in the service valve is NOT expected to have a perfect seal, that is
    why the cap has a washer on it.

    If the shrader valve is leaking you can replace that separately. The spring
    that maintains pressure on the seal my break and cause the freon to leak out
    at a fast rate. The only problem is if you cant get that valve from any
    place other then the dealer its gonna cost you about $80.
    Take a walk through a junk yard and pop one off.

  4. Thanks to all for feedback on this one. The plastic valve cover had been
    installed incorrectly (cross-threaded). I cleaned the plastic out of the
    threads of the valve and installed a new plastic cap and o-ring. The
    leaking has stopped.
