{"product_id":"radium-universal-coolant-tank-1240ml","title":"Radium Universal Coolant Tank, 1240ml","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.\u003cbr\u003e\u003cbr\u003eThis Radium Coolant Expansion Tank holds 1240mL. It is a multi-piece design constructed of CNC billet 6061 aluminum.\u003cbr\u003e\u003cbr\u003eA 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.\u003cbr\u003e\u003cbr\u003eNOTE: This product is not a coolant overflow tank. Instead, it is designed to be a part of the pressurized coolant system.\u003cbr\u003e\u003cbr\u003ePRESSURE CAPS\u003cbr\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.

This is the inlet for incoming hot water and is a natural bleed for the system.\u003cbr\u003e10AN ORB (7\/8\"-14) bottom port (opposite the inlet port) This is the drain back outlet. It would typically plumb to the water pump inlet fitting on the suction side.\u003cbr\u003e10AN ORB (7\/8\"-14) bottom port (under the inlet port). This is not commonly used. If applicable, connect it to the highest point of the engine. This will allow any air bubbles trapped in the radiator or engine to travel up to the coolant tank.\u003cbr\u003eBarbed cap fitting.
