Subject: Re: A/C help by CentralCoaster on 2009/3/9 16:42:56 The high pressure side is after the compressor and before the condenser up front, the small one. Do you have the funky small GM fitting? I had to buy an adapter for it from that auto a/c site with the forum, I forget the url. The low side is on the accumulator (which is on the compressor inlet side). A fellow CF'er helped me with mine. Or more correctly, I helped him while he did most of the work. I used about 4.5 cans. 4 cans probably would've been fine. Basically it's hard to get everything out of the last few cans because the system pressure is that much higher and the pressure in the cans can't overcome it as easily. I had to jumper the compressor at the low pressure switch. If your system already has some charge, you may not need to. I changed the accumulator, it does most of it's work on the initial startup, especially on a dead system with new components. I guess we must have added the oil first, although you can also just pour it in if the system is completely empty. You don't want to leave the compressor jumpered any longer than you have to. I would recommend getting ahold of someone more experienced to help you through it. Make sure your hoses will seal up well, two of the hoses that I tried using were defective right out of the package. |
