when you are burping the coolanst system just start the car let it get up to operating temp, open the radiator cap carefully and go at it. Fill it to the brim, wait for it to burp down a little and fill it some more. A very tedious process and a little time consuming but if you don't you'll hit spots when your cars temp will rise and fall whenever it hits an air bubble in they system. That's what happened to my Legacy when I got it up and running after it's accident.
