Radium Radiator Cap.
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.
