Radium Coolant Expansion Tank Kit - Ford Mustang GT S550 FM/FN 15-22

Application: Ford Mustang S550 (2015-2023) incl. Shelby GT350 and Shelby GT500
Part Type: Billet aluminium coolant expansion tank kit
Part Number: 20-0286

The Radium Coolant Tank Kit replaces the factory plastic coolant expansion tank at the front of the engine bay with a CNC-machined billet aluminium header tank, made from two halves bolted together. Its low-profile design frees up engine bay space for forced induction or other modifications.

Inside, the two chambers are linked by cross-over passages at the top and bottom, and an internal swirl feature helps de-aerate the cooling system. The kit includes all the parts needed for installation and no permanent vehicle modifications are required.
