Unlike an overflow reservoir, this tank becomes part of the \u003cstrong\u003epressurized cooling system\u003c\/strong\u003e, allowing the radiator to remain completely filled with coolant while providing space for thermal expansion. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe 750mL tank is CNC machined from \u003cstrong\u003e6061 billet aluminum\u003c\/strong\u003e and uses a two-piece construction with internal crossover passages. An internal swirl chamber directs incoming hot coolant tangentially through the tank to help separate trapped air from the coolant before it returns to the engine, improving system bleeding and reducing aeration. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eFor flexible custom plumbing, the tank has a \u003cstrong\u003e6AN ORB inlet and two 10AN ORB bottom ports\u003c\/strong\u003e.
