Hi,
Does anyone have experience repairing/changing an ac compressor (clutch) of a 2008 Chevy Cobalt LS?

 

No, but at the age of your vehicle, I'd just swap out the entire A/C compressor/clutch. I am too old to mess around with saving a few bucks as my time here on Earth is limited. As for your question, you'll easily find it on YouTube. We only had Manufacturer, Chilton, and Hayes Manuals, when I was young. Perhaps another person will give you better advice than mine. No matter, the best of luck to you, TJ7!

BTW, this man might be able to answer your question:
