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 reducing air pocket cavitation at the water pump.

TracTuff products use what Radium Engineering calls their "Type A" cap. I do not stock the Type B cap because it does not fit my products. Please, only consider adding when you are buying any of my products that incorporate a radiator cap bung.
