Universal Coolant Tank, 1240ml

Coolant expansion tanks are necessary for proper air bleeding in applications that utilize a rear mounted radiator or a low mounted radiator such as a V-Mount. However, expansion tanks are also valuable if integrated in a common radiator setup. To allow heat expansion, traditional coolant systems require air to be present in the top portion of the radiator during low temperatures. A coolant expansion tank permits the radiator to be 100% filled with coolant in all conditions. This Radium Coolant Expansion Tank holds 1240mL. It is a multi-piece design constructed of CNC billet 6061 aluminum. A pressure cap is not included. The CNC billet receiver is compatible with Type-A "radiator" caps, as shown HERE. The tank features two internal chambers. These chambers are NOT isolated from each other. There are cross-over passages at the top and bottom. NOTE: This product is not a coolant overflow tank. Instead, it is designed to be a part of the pressurized coolant system. PRESSURE CAPS The optional Radium Engineering pressure caps (sold separately) allow the user to select a range of pressure. The purpose of a high pressure cap is to increase the boiling point in the cooling system providing improved cooling efficiency. Each cap is manufactured from stainless steel with a race proven high pressure valve. This is something to consider when tracking the vehicle in extreme conditions. For more information, go HERE.
