Machined Aluminium Coolant Expansion Tank 
for Ford Mustang 2.3L EcoBoost / 5.0L GT 2015-23

Manufactured by Radium Engineering | #20-0286

Radium Coolant Expansion tank is designed to fit the 6th Gen S550 Mustang with either the 2.3L EcoBoost or 5.0L V8 engine.

These kits are designed to replace the plastic coolant tank found at the front of the engine bay. These coolant tanks are compatible with the Ford Mustang (GT, EcoBoost, V6) as well as Shelby GT350 and Shelby GT500.

The Radium Engineering coolant expansion tank is CNC machined from aluminium and consists of two halves that are bolted together.

The low-profile design allows extra room in the engine bay for aftermarket forced induction or other modifications. The internal design features two chambers that are NOT isolated from each other. There are cross-over passages at the top and bottom. The Radium Engineering coolant header tank also has an internal swirl feature, which is to help aid in de-aerating the system.

The kits include all parts necessary for installation. No permanent vehicle modifications are required.
