Description
The Radium Engineering Coolant Tank for Kit - 2023+ Toyota GR Corolla is engineered as a purpose-built solution for enthusiasts who want the surrounding system to be easier to package, service and trust under hard use.
Why This Upgrade Matters
An expansion tank provides a controlled high point for coolant expansion and air separation. In hard-use vehicles, a rigid, serviceable tank and well-planned hose routing can improve durability and make the cooling system easier to bleed and inspect.
Product-Specific Details
Because of continuous and intense heat cycling with track use, plastic coolant tanks have a reputation of failing over time. Fortunately, the rugged 2-piece Radium Engineering replacement is CNC machined and anodized for increased longevity. 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 kit directly replaces the plastic Toyota tank. A specially designed mounting bracket secures to existing threaded holes and adapter fittings interface with the factory hoses. The tank functionality remains the same as the OEM cooling system. Furthermore, the tank holds the same volume of coolant as the factory tank. However, the reduced size allows more room in the engine bay for other modifications and easier access to the engine for servicing. The Radium.
Fitment & Application
Application: Kit - 2023+ Toyota GR Corolla
Fitment style: Application-Specific
Technical Notes
Expansion-tank placement and hose routing determine whether the tank can function as an effective high point for bleeding. Use the pressure-cap type and relief pressure specified for the application rather than selecting a higher-pressure cap simply as an upgrade.
Radium Part Number
RAD20-0767
Enthusiast Notes
For cars that live through repeated heat cycles, track sessions and frequent maintenance, the upgrade is as much about durability and serviceability as appearance.
Before Ordering
Confirm vehicle fitment or, for universal tanks, available mounting space, hose routing and pressure-cap requirements. Pressure caps and application-specific hoses may be separate.
