    Can you post a parts list please

      I think this is what I used, if you have a different system then parts and quantities may change. Double check you have the same compressor since I think there are 2 that look like mine. I think I looked at the total system oil capacity and used that for the R134 oil but again double check that since it's been a year since I did the work.
      - 8oz of PAG 150 compressor oil
      - Universal set of green AC o-rings. The new lines should have most of what will be needed.
      - New flexible AC lines. (I used Rock auto)
      - New Accumulator (I used Rock auto)
      - New orifice tube. The ones I saw were recommended for both r12 and r134 (I used Rock auto)
      - New low pressure switch (Whatever one Advance Auto had)
      - Kit with conversion fittings (the car already had them installed but most parts stores or Amazon should have them)
      - Compressor o-ring kit (Santech MT2119 through Orielly's)
      - Condenser (MyParts PA-4823653 through Amazon)
      - I think mine took (3) 12oz cans but don't remember for certain, I charged it until the pressures were correct for the ambient temperature.
      Hope that helps, Thanks

    I had that same vehicle. The A C with R 12 worked great.
    Nice video. Very detailed explanation about the conversion to R134a.

    Gotta do the same to mine! Its not too bad up here in NE TN. low 80s, but still, that's worth the time to get it working again. I ended up chucking the lines and old compressor and condenser since they were just old and didn't hold a charge, plus the pulley was making a loud shrieking sound, so now its only got a bypass pulley. These pancake compressors are really nice and are super easy to service and remove.

      For sure, working AC is definitely worth having

    The only thing that you left out that I would’ve certainly done is flushed the evaporator because there’s mineral oil left in there the R12 system.

    Did you need to change the low pressure switch? They are specific to r12 vs r134a? If changed out, what is the part number for the one you used?

      The one I had was bad so I replaced it. I think they are specific as the new one is labeled R134. I bought mine through advance auto and it blew out after 9 months, they warrantied it so I get to see how long this new one lasts

    My 79 Transam had a leaked all the R12 so put I changed the o rings and put a vacuum on for 30 minutes, changed the charge fittings to R134 charged it up and it puts out 45 degree air when driving at highway speeds.

      You may want to check and see how the compressor is lubricated. If it's lubricated by mixing oil into the refrigerant, the old R12 oil likely won't atomize into the R134 and can cause compressor damage

    I cant seem to find the condenser you listed in the comments. Is the parts number 52456127 compatible?

    • @PracticallyStock
      @PracticallyStock  2 месяца назад

      here is a link: www.amazon.com/MyParts-AC-Condenser-Compatible-52456127/dp/B097PYG9BG
      That listing says the number you listed is compatible with the one I listed but I don't know what the different is between the two. Make sure it has the correct style of tubes as I mentioned in the video because the number you have may be for the OEM condenser

    Will the expension valve need to be changed ?

    • @brcmotorbathinda8752
      @brcmotorbathinda8752 2 месяца назад

      R 12 expension valve replace with r 134 valve

    • @PracticallyStock

      This system uses an orifice tube instead of an expansion valve, the orifice tube had the same part number for both refrigerants. Ideally you would want to change to the correct one for the refrigerant if one is available
