You did not mention how to purge air from system to complete procedure.

I am still unable to open illustrations. These will be needed to do procedure. Can you send them in another format or suggest suggest a format to open. I have many players installed and none will work? The ALLData site that this information came from requires a password XXXXX access links. Perhaps that's why I cannot open Pics?


Please advise
