not sure how to get all the oil out. maybe I'll just add a little ester oil when I recharge it with freeze 12. the system was never opened, maybe I should not mess with the expansion valve? |
If you had all those refrigerants in there I would definitly flush and replace expansion valve and drier. since no professional will ever touch your car, I suggest you do a lot of reading, and buy an A/C manual as I did.
