Hi all. Need your help. My AC system is empty and I want to charge it. Need to know which charging valve is the High Pressure one and which is the Low Pressure one. Both are identical and with a black screwed cap. I think the #1 (near the dryer) is the HP one, and the #2 is the LP one. can someone confirm? And what is the approximative R12 refrigerant system capacity? Thank you in advance...
Effectively, I made a charge using the #2 LP valve and now my AC works perfectly. I don't use r134, I made the charge with Duracool12a (2 ½ X 6 oz. cans) + Duradry (1 X 6 oz. can). http://www.duracool.com/Duracool/faqs.html
