Product Description

The Radium Engineering 20-0270-00 Universal Coolant Expansion Tank is designed for custom and performance applications requiring a high-quality, durable, and efficient coolant management solution. Constructed from CNC-machined billet 6061 aluminum, this tank features a two-piece design with bolted assembly, ensuring long-lasting performance even under demanding conditions.

Unlike traditional overflow tanks, this expansion tank is designed to be part of the pressurized coolant system. It includes an internal swirl chamber that aids in the deaeration of the coolant system, improving overall engine cooling efficiency. The tank features cross-over passages between its internal chambers, enhancing fluid dynamics and ensuring consistent coolant flow.

The Radium expansion tank accepts a standard 32mm "Mini" style pressure cap with a Type-A seal, allowing users to select the appropriate pressure rating for their specific application. The included billet aluminum pressure cap receiver ensures a secure fit. For mounting, the tank comes with a laser-cut, black powder-coated aluminum bracket, and all necessary fittings, hose ends, and hardware are included for a complete installation.

Whether you're building a custom cooling system or upgrading an existing setup, the Radium Engineering 20-0270-00 Universal Coolant Expansion Tank offers the quality and performance needed to keep your engine running at optimal temperatures.
