Found an interesting item on the car today. The rad cap tested and holds 15 psi. However the top of the rad cap had antifreeze on it around a rivet (or pin though the cap face) and when I tried to blow though, I could.
Is it possible the rad pressureizes, fills the overflow tank but when it cools and the pressure goes off instead of sucking antifreeze from the overflow tank, I just get air though this top of the cap?
