Turn to Allstar Performance high-pressure recovery radiator caps when you turn up the heat. Higher cooling system pressure raises the boiling point of coolant to reduce the risk of overheating—especially in racing applications. Recovery system caps allow coolant to exit the cooling system into an overflow or recovery bottle as the coolant heats and expands. As the system cools, recovery system caps will draw coolant back in to keep the cooling system full. Allstar steel or billet aluminum caps are available in different shapes, styles, and psi limits. Choose the model best suited for your radiator.
