16 PSI radiator cap designed to raise cooling system pressure, increasing the boiling point of coolant to help reduce the risk of overheating. Standard size fits 2-1/8" O.D. x 3/4" deep necks. This is a recovery style cap, allowing coolant to exit into an overflow or recovery bottle as the engine warms up and then return to the radiator as it cools.
