The main tank is a 2-piece design constructed of billet aluminum. The two halves are bolted together along with a CNC billet aluminum cap receiver which mates to any standard 32mm \"Type-A\" style pressure cap.\u003c\/p\u003e\n\u003cp\u003eThe Radium Engineering tank also has a swirl feature, as shown. Pressurized coolant is sent into the vortex chamber's inlet tangentially and accelerated to a high rate of rotation. This is an old hot rod trick to help aid in de-aerating the system.\u003c\/p\u003e\n\u003cp\u003eThe S2 Lotus Elise, Lotus Exige, and Lotus 2-Eleven comes standard with a Denso coolant expansion tank. This is the same plastic tank that is found in the Toyota 2ZZ-GE equipped vehicles. For fitment, Lotus designed a complex bracket that incorporates a mount for the electric hot-soak water pump. There has been cases reported where the Denso tank has failed and owners have found that new replacements are quite expensive. Radium has simplified the Lotus design by making two separate mounts and further improved it using a robust aluminum tank and adapting the factory hoses to 6AN fittings.\u003c\/p\u003e\n\u003cp\u003eThe mount uses all factory threaded mounted holes. Because of this, there is no need to drill or modify anything as it bolts in. Install is a fairly simple process that can be performed by an average mechanic. Everything is accessible with the rear clam intact. Aluminum Pushlok hose ends are included to convert the factory coolant hoses into 6AN.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003ePRESSURE CAP\u003c\/h3\u003e\n\u003cp\u003eThe optional Radium Engineering pressure caps (sold separately) allow the user to select a range of pressure that was not possible with the Denso tank. 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.
