Does anyone have part #'s for the bleeder screws?My mopar alum. housing has an 1/8" pipe port on top that would work great.I went to a couple parts houses,and no one could help. Does it really work even though the bleeder is lower than the top of the radiator?I have a stock radiator in my coronet,and see no water movement,but it does cool o.k.I should see water moving,right?
