    If you have this big of a leak it should be fairly obvious as to where the leak is, and if you can't determine where it is (sometimes it is very difficult) then I suggest having a professional locate the leak.
    Call some of these shops if you need help: http://repairpal.com/directory?address=21613&car_bran...

    This just doesn't make sense. I suggest taking it to another shop.

    Head gasket failure is common on the North Star. It will consume coolant in that amount. Usuall though you can smell it in the exaust.
