Product Description

The Radium Engineering 20-0285 Billet Coolant Tank Kit was developed specifically for the 2011-14 Ford Mustang (S-197 platform) to replace the original plastic expansion tank with a high-strength, track-capable aluminium unit. Its dual-chamber swirl design helps eliminate air from the cooling system, which is especially beneficial for performance or forced-induction builds where radiator locations and hose routing may introduce air and temperature issues.

Offering direct-fit installation with all necessary bracketry and hoses included, this kit simplifies the upgrade process while providing significant performance benefits - such as improved coolant flow, better durability in high-heat environments and the ability to pair with high-pressure radiator caps for increased boiling point. Ideal for owners upgrading their Mustang with enhanced cooling systems or preparing for track duty.
