Magnet Posted March 31, 2019 Share Posted March 31, 2019 Hello Richard, It’s probably time to stop Googling and simply get the system flushed and regassed, since it has to be done anyway. The people carrying out this procedure usual thoroughly check the system anyway. Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
