I bought a new ac compressor for my 2006 Chevy SSR. I had recovered the refrigerant pulled the old compressor put the new one in and filled the system with 50 pounds of nitrogen. It held for 30 minutes and did not move. So I pulled a 1 hour vacuum on the system it has held so I am ready to fill it with 134a. Now I am debating weather to fill it up while the compressor is in a vacuum. I know before I start the truck I have to charge some refrigerant in. Do I fill the system while it is in a vacuum and do I charge it in as a liquid before I start the truck. I like filling it as a gas I don't trust filling it as a liquid but this is where I am at now. Thanks.
