{"product_id":"radium-universal-billet-coolant-tank-822ml","title":"Radium - Universal Billet Coolant Expansion Tank (822mL)","description":"\u003cp\u003eCoolant 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.\u003c\/p\u003e\n\u003cp\u003eThis Radium Coolant Expansion Tank holds 822mL. It is a 2-piece design constructed of CNC billet 6061 aluminum. The two halves (shown below) are bolted together along with a CNC billet aluminum neck.\u003c\/p\u003e\n\u003cp\u003eA pressure cap is not included. The CNC billet receiver is compatible with Type-A \"radiator\" caps, as shown \u003ca rel=\"noopener\" href=\"\/products\/radium-radium-high-pressure-billet-radiator-caps-type-a\" target=\"_blank\"\u003eHERE\u003c\/a\u003e. The tank features two internal chambers. These chambers are NOT isolated from each other. There are cross-over passages at the top and bottom. \u003c\/p\u003e\n\u003cp\u003eThis product is not a coolant overflow tank. Instead, it is designed to be a part of the pressurized coolant system.\u003c\/p\u003e\n\u003cp\u003eThe Radium Engineering coolant expansion tank also has an internal swirl feature, as shown. Hot pressurized coolant from the cylinder head is sent into the vortex chamber's inlet tangentially and accelerated to a high rate of rotation. This is to prevent aeration in the system.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003ePRESSURE CAPS\u003c\/h3\u003e\n\u003cp\u003eThe 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.
