    Right on top of the compressor at the hose connections.

    It's at the hose connections,
    but you've got the cylindrical type compressor with
    the hoses on the back end. Not sure if
    the fill ports are accessable w/o going in thru the fender
    well.

    A quick accessability check would be to see if removing the airbox
    cover & bellows would give access.

    Well, once it's done, don't complain if your cojones freeze off & your girlfriend dujour is frigid(LOL).

    Seriously, let us know how it comes out.

    Thanks Verell for the inquiry my friend. It went fine and they spent about 30 minutes taking out the old stuff, it held good pressure at 28, but we had some questions about it maintaining as it dropped a SMALL touch so i had them add a bit of dye just in case any future leaks happen.

    She is blowing COLD now and i used my blacklight last night and saw NO dye around the front or rear. Actually i am amazed how cold it blows considering all the "mouse blowing on an ice cube" jokes. He did a basic themo and it dropped to (i forget). i do have a thermo here, but in the end it blows COLD COLD COLD. i also checked the thermo adjust and that seems to work as well.

    FYI: Paid $100 for 2 lbs of R-12 and another $100 for labor as the job took about 90 minutes as they REALLY did a few checkups on the system as well. We all wanted to make sure the system was evacuated well and whatnot. Seeing how the change over would have been SIX hours of labor i felt this was the easy/cheap fix... until i need more R-12 in a few years :(

    Sounds like a success! Of course now that we've got our A/Cs working, the weather will stay cool until winter(LOL).

    BTW, the 6 hours was an 'up-side', very conservative estimate because I haven't pulled a Sanden & drained it.

    I've seen that vacuum drop a couple of times on other systems, including my 308. Moisture starting to boil off will cause it. However, your system was under positive pressure so moisture is pretty unlikely. Possibly oil was slowly sucked out of the shaft seal & let a tiny trickle of air in. In every case, the system held refrigerant quite well. The real test is how well it holds coolant vs time.

    The dye is always a good insurance.

    BTW, In addition to a UV leak detection setup, I've got a Snap-On electronic leak detecter that is spec'd to detect a 1/2 oz/year or less leak if it's ever needed. It sings out when near the YORK compressor's shaft seal which is spec'd at 1 oz./year.

    BTW, that's an old A/C service scam. Shove a sensitive leak detecter under the shaft seal & let it sing out. "I'm sorry, but as you can hear, your compressor seals are bad, you need a new compressor..."

    Agreed. May as well do it just in case and it hurts nothing.


    The guys who did my servicing were very friendly, knowledgeable, and in fact the main guy was a 80's Porsche guy. He had an 1981 911SC or some such he toys with so we had fun ribbing each other about the old crap car the other has... all in good friendly jest.
