This is especially useful with engine-bay changes such as turbocharger systems, engine swaps, or other custom configurations that create clearance issues around the original tank location.\u003c\/p\u003e\n\u003cp\u003eThe tank is CNC-machined from 6061 billet aluminum and uses a two-piece construction with an internal swirl chamber. Hot coolant enters the chamber tangentially, creating a vortex that helps separate trapped air from the coolant before it returns to the system. This helps improve bleeding and coolant circulation in performance cooling systems.\u003c\/p\u003e\n\u003cp\u003eRadium includes a dedicated firewall mounting bracket, 6AN adapters, sight-tube fittings, pressure-bleed nipple, and mounting hardware. The tank accepts a standard 32mm Type-A pressure cap, allowing the pressure rating to be selected separately for the application. Radium's installation instructions specifically address mounting on 2006-2011 Elise\/Exige models.\u003c\/p\u003e","brand":"Radium Engineering","offers":[{"title":"Default Title","offer_id":49207025991931,"sku":"rad20-0270-02","price":294.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0717\/5893\/files\/509782515479f77f33cca75a49672ad2L.jpg?v=1787348371","url":"https:\/\/www.pandamotorworks.com\/products\/radium-engineering-06-11-elise-exige-2zz-ge-only-coolant-expansion-tank-remote-location","provider":"Panda Motorworks","version":"1.0","type":"link"}
