Allstar Performance Radiator Cap — 28-32 PSI Small Diameter (32mm) | ALL30126 2019-chevrolet-blazer-esi6327632 All Mishimoto fan shrouds areThe Allstar Performance Radiator Cap (ALL30126) is a round, recovery style cap rated 28 32 PSI, sized for small diameter radiator necks measuring 32 mm. Recovery style caps allow coolant to expand into an overflow bottle as the cooling system heats and draw it back in as the system cools, helping keep the system full. A higher pressure rating raises the coolant's boiling point, which reduces the risk of overheating. Spec Sheet: Allstar Performance
