Keep the R12 Have an AC shop pull the system down with vacuum and see if it holds - no leaks first.
From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Friday, April 18, 2008 1:32 PM To: [email protected] Subject: [Chevelle-list] A/C Question... Has anybody ever converted thier R12 to R134A? I have this 62 Cadillac that has A/C. I thought it might be neat if the A/C worked on it. I have to convert it over to 134A right? I'm assuming that there is zero refrigerant in the system right now. I've done a little research on it and it appears that besides vacuuming out any remaining R12, I need to change the compressor oil? The compressor spins freely, and smoothly. I have zero A/C experience. Do I need to change out anything else?
