OVERVIEW

Replace the failure-prone factory plastic reservoir in your 2023+ Toyota GR Corolla with the Radium Engineering Billet Coolant Tank Kit. Under intense heat-cycling and track use, stock plastic tanks can embrittle and leak. Radium's rugged two-piece CNC-machined aluminum replacement provides superior thermal conductivity and long-term durability. Featuring internal dual chambers with cross-over passages and an integrated swirl feature, this kit actively aids in de-aerating the cooling system while holding the exact same volume as OEM in a sleeker, more compact footprint.

FEATURES

• Direct Replacement: Engineered specifically for the Toyota GR Corolla, securing directly to factory mounting locations.
• 2-Piece Billet Aluminum Construction: CNC-machined and anodized for enhanced heat dissipation and resistance to high-temperature degradation.
