The Radium Engineering coolant expansion tank relocates the coolant reservoir for 2006–2011 Elise and Exige models equipped with the 2ZZ-GE engine to a remote position. The low-profile CNC-machined aluminum unit uses a two-chamber layout with cross-over passages, an internal swirl feature, laser-etched and anodized surfaces, and stainless steel hardware for a finished remote coolant solution.
