George Rohrbach Posted August 12, 2018 Report Posted August 12, 2018 After replacing both leaking valves on the compressor (so no Freon), I am ready to vacuum pump down, and charge up. I am staying with R12, as I have a tank, and know the specs are for fill 3 lbs., and check the sight gauge for bubbles. I bought some Supercool Ester Oil that says compatible with R134a and R12. The question is: How do I tell how much oil to put in, if any? I do not want to take all components off, try to dump and see what is in there now. Anybody help Please! George Rohrbach
George Rohrbach Posted August 12, 2018 Author Report Posted August 12, 2018 Here is what I decided to do: Since the slow leak that I had was the valves, and not a catastrophic failure that would have blown out a lot of oil with the Freon, I just added 1 oz. The diagram was helpful, but the fill plug is on the side where the mounting is, so no way to get to it, without taking off more than I wanted to, at this point in time.If I have any issues, I will take off, and also take off all the other parts for renewal at the same time. But I would probably keep the original York. >>>>Posted on SDC Forum By Brad Bez Bez Auto Alchemy
