Subject: adding refridgerant to '94 318i Author: netdude : member since February, 2005 : 5 posts Posted on: 2005-05-31 11:42:05

hi. I've purchased the recharger kit. I know a little bit about R-134a and I'm pretty sure about how to charge the system, but I have one question. I am not sure if I have a leak in the system or what the deal is. I had the system filled about 3 years ago, and about 2 years later (1 year ago), the system only spits out hot air. I checked the pressure with the AC running, and it's way low, indicating that it's time for a recharge. When I have the AC off, it's at about 30 psi or so. Does that tell me that the system is NOT leaking? Also, I've read on some sites that I should have the system "evaculated" by a shop and in so doing, would "recreate" the vacuum in the system. Now to the question: is there any way to tell if I have a good vacuum in the system without having a shop doing it for me? It makes perfect sense that there should be a vacuum in the system prior to me refilling the R-134a, but I'd hate to pay the shop to do something that isn't necessary. Any thoughts? Thanks
