Thanks Dave. The car is not quite drivable, but I can perform that procedure in my driveway. Any estimate on how long I should run the car with the cap off and when do I put the cap back on? Sorry for the lame questions, I am trying to make sure I don't get rid of one air bubble just to introduce another - since I am not sure how they come about in the first place. Maybe because I did not have a overflow hooked up - and it sucked in air while cooling?
