can a/c compressor clutch on nissan sentra 2011 2.0 be replaced without replacing whole compressor

Almost all A/C clutches are replaceable. You might have trouble finding OEM or comparable parts though. Should be around for about 50 bucks which is better than the 350 for a new compressor.

Plus I don't have to open the system. I am thinking about going to junkyard and getting compressor. Dealer wants 1200 dollars to replace the compressor. Other folks want 600. I'll do my research and do it myself. It's not like rocket science. Yes? Just have never had to do an A/C system on a vehicle before. I can usually get there in whatever it is. Once I understand what to do.

Yeah it's a breeze in most cars provided you do a little prep work. Eric the Car Guy has a great video on it here https://www.youtube.com/watch?v=j7yflp1WFrU I think he has another on completely swapping the compressor. if not, ChrisFix does. Best of luck Lonnie! It might also be cheaper just to get one from autozone.

I did watch Chrisfix and a bunch of his videos from diagnostics on. He did does a great job also. Here is that link. I did also watch some diagnostics stuff on eric the car guy, too. I'll check out that video also. Thanks. Compressor at autozone is 310 and they say the clutch is not a separate item. Or maybe that was Reilly's. I'll have to ask auto-zone again.
