RADIUM ENGINEERING COOLANT TANK KIT - HONDA CIVIC TYPE R FL5 [2023+]

Due to continuous and intense heat cycling, plastic coolant tanks have a reputation of failing over time. The rugged 2-piece CNC machined aluminum Radium Engineering has increased longevity. Additionally, the metal construction is robust enough to use in racing applications.

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