rockfangd Posted August 20, 2017 Report Share Posted August 20, 2017 Hi all. I had to replace the ac compressor, orifice tube, and a few other parts related with the AC on my 1997 Deville. It blows cold and works good if driven daily, But if the car sits for a few days and I turn the AC on the compressor makes a noise that does not sound good. Sounds like it is straining for a few seconds, then all is fine. I am thinking maybe there is too much oil in the system.. Does it seem like I have the right idea. Only reason why I think that is because it does not do it unless the car sits for more than a day or so. Before I discharge it and check the oil I figured I would see if it sounds familiar to anyone else.

barczy01 Posted August 20, 2017 Report Share Posted August 20, 2017 I drain the compressor of its contents and add 2 oz of oil and that's it. In this case to much of a good thing (oil) harms system performance. Link to comment Share on other sites More sharing options...
rockfangd Posted August 20, 2017 Author Report Share Posted August 20, 2017 More than likely that is what I did when I installed it, but that doesn't mean it didnt already have too much. Is it possible to do it without removing it... Hmm GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
