Interesting, so should you always fill coolant with the bleed hole open? I haven’t had an overheating issue, but is this just a good practice in general to prevent air pockets? My antifreeze does seem to burn off rather quickly too, could not bleeding it be part of theÃ¯Â»Â¿ problem? And lastly, I have been battling a vacuum issue (code p1192) for months, any idea if this could be connected? Thanks VERY much, great vid!
