So my a/c is leaking at least out of the low side service port. I am planning on fixing. I have the vacuum pump and gauges. Im going to replace the service shrader valves and pull vacuum and recharge. My question is how much (by weight) refrigerant do I put it in it? I have been unable to easily find the amount searching around for a 98 Yukon WITHOUT rear air. Im assuming it would be the same as any 98 silverado/sierra, can anyone provide me the amount of refrigerant by weight please? Also, see the attached media file. You can see the oil bubbling out of the leak. Is that a concern? Does oil need to be added? I dont want to add too much of course. Any input from some experienced a/c folks?
