Hi on my dads 2006 Chevy SSR I replaced the compressor the compressor seized. I put the new one in and filled it back up the refrigerant now comes out green and stinks like garbage. I flushed the system when I change the compressor changed the accumulator and also the filter in the line. I would say this sounds like moisture in the system but I am not to sure. What is your opinion. What can I do to fix this. I can recover the fluid vacuum the system and clean the lines again and re pressurize the system with nitrogen again. Does the compressor oil need to be changed. Then re vacuum it and fill it up again.

When a compressor seizes it sends junk through the system. The new compressor if not filledwith oil should be to the correct level with the correct oil. The lines have to be disconnected at the orfice and back flushed with they have available at auto parts. It should be liquid not a gas. Then you need a new orfice and drier an dwatever else you are installing. It shold be evacuated for 30 minutes at 28"vacuum and a Freon sweep done at 15 minutes prior to filling. Oil for compressor shold be put in at time of compressor install. You need to use pag oil see pic for proper procedure

Yeah I did all that I actually did a 30 minute vacuum then put nitrogen in it then evacuated it after 30 minutes of nitrogen then re vacuumed it for 1 hour then 30 minutes later filled it with 50 psi of liquid nitrogen just to get something in the system then let it sit and filled it up the rest of the way with gas. The new compressor was pre filled with oil to the correct amount by recommended specification. I also drained the old oil and new in two clean cups and it was measured the same and then I dumped it back in the compressor. I hope I did it right. I also replaced what I had said in the previous post. Thanks.
