I've been spending the last couple of weeks fixing my a/c after the compressor seized and snapped the belt. A P/O had converted it to r134a. I replaced the drier, expansion valve, new remanufactured compressor, synthetic BG Frigquiet oil, and thoroughly flushed the system. I also used Nylog on all the seals and put r12 back in. I took it to a shop to have it vaccumed down but I don't think they did a good job. They only pulled a vaccum for 20 minutes and I think they let all the air back in when the guy took off his gauge. Vent temps will get down to about 60°F within a minute, 50° after about five, and they'll only get down to 43°F, the coldest I've seen, after extended highway driving. These numbers came when it was 90-100°F outside, by the way. When idling for more than five minutes, temps will rise to 60°F, and the aux fan does come on. Does this sound right to you guys? Will it be worth the effort to take it to my indy and have him evacuate and pull a really good vaccum on it? I'm just glad its working but its been so hot, I'd be willing to spend the extra $$$ to get it colder. Thanks.
