Would any of you know whats going on here? Just last night i was driving down the road and my car overheated hitting the redline and as it happened the heater stopped blowing out hot air, then a few seconds later it cooled down and it was fine again... when it kooled i checked the coolent and it was barly missing any. my friend and pops assumed it was an air pocket but i dunno it did it a few times that night... thanks!
