The ball, spring and housing are there. Looks like the spring holds the ball up into the hole in the bottom of the housing. I can push down on the ball to open the hole. Is that the way it’s supposed to work? That looks like the passage by which cooling water gets into the head. So how does water get in when the ball valve appears to be closed all the time? What opens it?
