allright, this is the last secret trick i am going to let out this winter.. I do what joe says, then place the bag on top of your defroster vent in your car... leave it there for a while- the heat will speed up the bleeding. Oh, and you can put some smelly jelly in there too, but make sure the bag is CLOSED TIGHT!! otherwise, you will have to take yoru car to the wrecking yard.
