The Radium Engineering Coolant Tank Kit is a direct-fit, CNC-machined billet aluminum replacement for the factory plastic coolant tank on the 2023+ Toyota GR Corolla. The rugged 2-piece anodized design retains factory volume and functionality, while aluminum improves heat transfer over the OEM plastic unit. An internal swirl feature and dual chambers with cross-over passages help de-aerate the cooling system, and all mounting hardware is included.
