I'm Awesome
Hey all, 94 Sierra with a 5.7 and factory R134 AC. It’s had issues with the ac since 2007, the previous owner kinda just gave up on it and I haven’t bothered with it much until last year, when I replaced the compressor, orfice tube, condenser, and the accumulator. The old system was all original and didn’t have any crap like metal flakes or dirt in it, so I know the system is clean. The AC compressor I bought was a reman and ended up being a pos, it locked up the clutch and threw the belt any time you turned the ac on, so I haven’t touched it since then. Now some of my issues also were user error, hence why I’m here. But anyways, it’s 95 degrees in OK and I just warrantied my old compressor and bought a brand new one. But I have a few questions about PAG oil.
Firstly, what kind should it use? I used PAG 150 last time, but i’m not sure if that was the best idea. If it helps, it’s a brand new Murray compressor.
Second, how much should I add? The sticker on the compressor said that it came with 3 oz already in it, but I don’t know if the oil in it is worth a damn or not.
Lastly, how do I get the oil to fill up in the compressor properly? I know to turn the clutch, but how can I do that when the compressor is out of the truck? That was something I didn’t do that last time and I want to do this one right.
