Radium Engineering Coolant Tank Kit | 2023+ Toyota GR Corolla (20-0767)

Three cylinders, three hundred horsepower, one plastic tank that never planned for this.

The Radium Engineering Coolant Tank Kit for the Toyota GR Corolla replaces the factory expansion tank on the 2023+ GZEA14H: billet aluminum construction that aids in heat transfer, a slim design that allows for more room in the engine bay, and direct fit replacement in the factory location. The cooling upgrade for a hot hatch whose engine bay runs crowded and hard.

What You'll Feel

• The plastic-tank aging problem retired from a hard-driven turbo triple
• Heat shed through the billet aluminum where plastic insulated
• Engine bay room reclaimed by the slim design
• A direct fit swap in the factory position

Features

• Billet aluminum coolant tank kit for the 2023+ Toyota GR Corolla

The Details

The GR Corolla's G16E works its cooling system hard by design, with a small-displacement turbo engine making big specific output and the crowded bay holding the heat close, and the tank upgrade addresses both sides: aluminum conducts what plastic traps, and the slimmer package opens space in a bay where every centimeter is negotiated. Installation swaps into the factory position with the system refilled and bled per Toyota's procedure. Pairs naturally with the rest of Radium's GR Corolla catalog, from the G16E fuel rail to the master cylinder brace.
