The radiator cap is an essential part of an upgraded cooling system. Radium caps are engineered to safely improve cooling efficiency by managing the boiling temperature. A higher radiator pressure effectively raises the coolant boiling point, providing an extra safety margin and preventing air pocket cavitation at the water pump.

NOTE: Traditionally, "radiator" caps are mounted to the radiator but can also be found on coolant expansion tanks.

Each OEM replacement radiator cap is manufactured from stamped stainless steel for durability. All 18-0076-X1X radiator caps are electroplated black. Unlike OEM caps which use natural rubber gaskets, these radiator caps feature premium silicone sealing elements for long lasting durability.

PRESSURE

Available with 3 different pressure relief springs:

  1. 1.1Bar (16.0psi)
  2. 1.3Bar (18.9psi)
  3. 1.5Bar (21.8psi)

TYPES

Radium radiator caps are designed for mini size (32mm ID) radiator necks only. Available in 2 common styles (Type-A and Type-B).

Please confirm what style your application uses prior to ordering.

NOTE: Radium Engineering coolant expansion tanks require a Type-A style radiator cap.
