Product Description

The Radium Engineering 20-0767 Coolant Tank Kit is a premium replacement for the OEM plastic coolant overflow/expansion tank on the 2023-2025 Toyota GR Corolla (GZEA14R). CNC-machined from robust aluminum with an anodized finish, this billet tank offers superior durability over the stock plastic part and improves heat transfer for enhanced reliability - especially benefitting track enthusiasts and high-temperature applications. Its internal two-chamber design with crossover passages and swirl feature helps deaerate coolant while maintaining the same fluid capacity as the OEM tank, all in a more compact package.

Installation is straightforward: the kit directly replaces the plastic factory tank using a custom mounting bracket and includes billet adapter fittings and an overflow hose. The streamlined build frees up engine bay space for easier access and additional modifications. With stainless steel hardware included, this Radium tank kit delivers both functional cooling performance and a high-quality upgrade in the engine bay of your GR Corolla.
