Hello, looking for some help with a 97 c2500 5.7 Vortec. About 3 months ago we replaced the dryer, hi side ac line and orifice tube. Today my ac stopped working and it's 113 out. Popped the hood and the alternator pulley wore a hole in the ac hose. Leaked out all refrigerant. My question is. How muck compressor oil has escaped with the refrigerant and how much should I replace?
