The Allstar Performance Radiator Cap with Lever (ALL30131) is a round, recovery-style cap rated 20-24 PSI, sized for standard size radiator necks. The lever lets you release cap pressure without fully removing the cap, reducing the risk of hot coolant spray when checking the system. Recovery-style caps allow coolant to expand into an overflow bottle as the system heats and draw it back in as the system cools.
