    So the AC coolant got drained when I replaced the radiator, I was told
    I would need all the air vacuumed out and refilled. I did that and
    when he refilled it a tube right above the battery blew up witht he
    sound of a shotgun. Since he was doing it for free I told him I would
    fix the tube and bring it back.

    How do I fix this tube?

    What car is this on (year, make, model)? Why was the AC system touched at
    all if all that was done was replacing the radiator? In most cases, all one
    needs to do is unbolt the evaporator and tilt it (while it is still
    connected and fully charged) to remove the radiator through the top.

    If you punctured one of the aluminum AC tubes, then you will need to replace
    it. (Scrap yard is probably the best source for this...) Depending on the
    vehicle, this will likely require special tools to remove the "quick
    connect" couplings. Also replace the rubber O-Rings at this time too. Once
    replaced, at minimum you will need to draw a vacuum to remove the
    air/humidity that contaminated it. It will need to hold the vacuum for at
    least an hour to assure the system is sealed and has no other leaks. Most
    would recommend replacing the receiver/dryer too, but that is a personal
    call if the vehicle is very old and you are not intending to keep it long.

    Good luck.

    (obviously you meant condensor, not evaporator there)
    Bob - He started posting a long time ago about this car - a '98 Concorde
    LXi. You are right - the FSM specifically says that it is unnecessary
    to disconnect any a.c. lines to remove the radiator.

    Maybe he said before, but my guess is he is not using an FSM.

    I didnt disconnect the lines, I took it out and the line moved a bit
    and started a slow leak, I had a guy who I knew was going to refil it
    for free since I was going to anyway so I let it empty.

    Yes, the condensor is indeed what I intended to say ... the evaporator is
    inside the passenger compartment along side the heater core. Thanks for the

  7. Like the other poster said a wrecker will have the needed tube.

    But be very careful if you go to a U-pull-it wrecking yard. A couple years
    ago I saw an intact system in a minivan that I wanted the condensor for,
    so I started to unbolt the compressor and the A/C line blew off in my face
    along with a whole lot of A/C oil and refrigerant - the morons at the
    yard hadn't evacuated the system before putting the van out into the yard.
    (probably violating a dozen EPA regulations) Fortunately I was wearing
    glasses. Happily, it ended out well since because I knew the system was
    intact I took the condensor, some lines, and the dryer and compressor,
    all of which I used in my van, and which are running fine to this day.

    Anyway, I think the guy that was filling it for you didn't know what he
    was doing and I think your nuts to take it back to him, but suit yourself.

    Notice how no mention was made of fixing the "slow leak" before
    re-charging it?

    Ummmm... WHY?!? There's no need to open the AC to replace the radiator
    on either generation of LH car...

    OK, never mind my previous post then.. When you say the line "blew up,"
    did it pop open at a joint, did a metal section fracture, or did a
    rubber hose section split open?

    If its a rubber section, you can just take the hose to a local
    hyudraulic or AC repair shop and have them put a new rubber section on
    your metal fittings. A blown out metal section probably means a trip to
    the dealer of a junkyard.
