Radium Engineering Coolant Tank – Universal 1240ml

The Radium Engineering Coolant Tank – Universal 1240ml replaces the factory coolant expansion tank with a purpose-built Radium reservoir while retaining the cooling systems fill, return, and expansion functions. The vehicle-specific layout is designed to fit the engine bay cleanly and provide a durable foundation for upgraded cooling-system plumbing.

This is a universal component, so final placement and surrounding plumbing depend on the way the rest of the system is built. This version is built around 1240ml capacity; verify those details against your existing plumbing and hardware before ordering. Confirm hose-port layout and vehicle fitment, then refill and bleed the cooling system using the vehicle manufacturer’s procedure.
