Radium Engineering 2015+ Ford Mustang GT / Boss 302 / V6 Coolant Tank Kit

The Radium Engineering 2015+ Ford Mustang GT / Boss 302 / V6 Coolant Tank Kit is designed so it 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.

Fitment is specific to Ford Mustang GT / Boss 302 / V6; confirm the vehicle and surrounding hardware before ordering. Confirm hose-port layout and vehicle fitment, then refill and bleed the cooling system using the vehicle manufacturer’s procedure.
