I was told that you turn the little nut on the top of the housing, but that never seemed to work for me. What is the correct way to bleed it so i don't end up getting in the system again?

thanks

if youre doing a flush just get a Prestone flush kit so you do it right. the screw on top of the housing is to relieve any air bubbles that might be in the system. also unscrewing your knock sensor will let the remaining coolant you have left out of the block.
