Coolant tank for the 2017+ Honda Civic Type-R and 2023+ Integra Type S (FK8,DE5 and FL5). Replaced OEM plastic tank. Easy bolt-in installation.

Because of continuous and intense heat cycles over time, plastic coolant tanks have a reputation of failing. Fortunately, the rugged 2-piece Radium Engineering replacement is CNC machined from aluminum. And because aluminum is a superior thermal conductor material, heat transfer is further improved. Additionally, the metal construction is robust enough to use in racing applications.

This FK8 Type-R kit directly replaces the plastic Honda tank without making permanent modifications to the vehicle. A specially designed mounting bracket secures to existing threaded holes and Radium adapter fittings interface with the factory lines. The tank functionality remains the same as the OEM cooling system.

The Radium Engineering Coolant Expansion Tank has proved itself over the years in many applications all over the world, in race and street vehicles. The internal volume of the Radium Engineering Coolant Expansion Tank is equivalent to the OEM tank resulting in no coolant loss. The internal design features two chambers with cross-over passages at the top and bottom. The coolant tank also has an internal swirl feature aiding in deaerating the system.

The kit includes all parts necessary for installation. NOTE: The OEM 1.3 Bar Honda pressure cap can be re-used.
