    Yup... system was 9 oz low. Just evacuated, I'm going to replace the leaky line, fill her back up, and enjoy flawlessly functioning cool air!!!

    Exactly which line was leaking?
    How did you determine that the line was leaking?
    How did you know that it was 9oz low?
    I highly recommend the PAG oil that has the ice32 additive!

    The leak is visible, right on the ac hose junction. I used a shop machine to evacuate the system, it pulled 1lb 4oz, the system is rated for 1lb 12oz (ok so 8 oz low). I'm trying to figure out which AC hose I need to get.

    Does Advance Auto carry the kind of oil you're talking about? I'd certainly like to get the most out of all this while I'm at it

    Also, the leak is from the hose circled, where the hose leads down to the compressor. Is that the discharge and suction line?

    Screw it. I'm going back to the shop tomorrow and just having them fill it up.

    So if I understand you correctly, you live near me and have access to a machine that does AC refrigerant recovery?

    Not sure of your whereabouts, but I'm in Bethesda. I have access to "inexpensive" AC machines (I paid $15 to evacuate my system). I'd be happy to help you out, if you need.

    So I ended up getting a couple cans of refrigerant at walmart, put 28 oz in the system, and voila!! All fixed hopefully the advertised "leak seal" prolongs the life of my AC system for a while. Spent all day yesterday running wires for new speakers because of the confounding "premium sound" wiring in this car. Pretty sick of fixing cars for the foreseeable future.

    But yeah, zzyzzx, shoot me a PM if I can be of assistance!

    I am in Baltimore City, near the stadiums.


    It won't! I've had better luck just assuming it was the compressor and replacing it. but that was on my Alero where the "V5" style compressor is famous for leaking at the seams and shaft seal. On my Escort I would assume it's the shaft seal. You really can't replace just the shaft seal on these compressors.

    Oh, you aren't far at all! In fact, the location of one of the machines I have access to is literally a halfway point between us. The way things are for me at the moment, the band-aid fix is the way to go for the time being, especially when that band-aid works well enough :D

    def a p/s line circled in the picture.. the suction hose is about 1 in diameter and runs across to the passenger side firewall area. the system will 'bleed' off refrigerant over time, its made by humans.. best bet is to suck it down to vac for 20 min, and have it recharged with a machine.

    Fort Meade Auto Skills Center - DIY mechanic shop with super low prices on various services, lift bay use, etc.

    Long enough :thumbsup:



    I had it evacuated and vacuumed with an AC machine then refilled it with canned refrigerant. Thus far it's working well. I'm going to see how long it continues to work well. If I can make it through the summer with the occasional use of one more can of refrigerant, I'll be content.
