I am going to put in a smart vov in my car. I want to do this myself but I have never done a full charge on an A/C system that has been open. Do you have to pull a vacuum on it, or replace the drier, add oil or what?? Or can you open it for a few minutes and then close it back up and charge it?? I have recharged a system that were a little low, that seemed fairly easy. Can someone give me a step by step on how to do this, I would greatly appreciate it.
94 944, 237,000 miles. Question how do you get the mileage badges?
