    The cap basically has two valves in it one to relieve pressure and one to recover coolant from the expansion tank. Look at neck in the radiator and the only thing after that I can think of if you had an acidic cooling system due to a blown head gasket the cap can fail. An acidic cooling system often turns the coolant from green to orange rust color.
