Radium Engineering Radiator Caps exhaust order your Alpha Widemouth DownpipesThe 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 (below).
