Chase Bays Radiator Cap Type A, 1.37bar / 20psi

If your cap has too low a spring pressure, your cap will push the fluid out prematurely and fill up the overflow. When we’re all driving our cars spiritedly this rapid rise in pressure is common and your stock cap is not built for this. A higher radiator cap pressure effectively raises the boiling temperature of the coolant, providing extra safety margin and preventing air pocket cavitation at the water pump.

Each replacement radiator cap is manufactured from stamped stainless steel for durability and feature silicone sealing elements that are superior to natural rubber gaskets.

Chase Bays Radiator Caps are designed for “mini” size (32mm ID) radiator necks only.
