Description
Radium Coolant Expansion Tank Kit - Ford Mustang GT S197 11-14
Application: 2011–2014 Ford Mustang (S197)
Part Type: Billet coolant expansion tank kit
Part Number: 20-0285
The Radium Coolant Tank Kit replaces the plastic coolant tank at the front of the engine bay on the 2011–2014 Mustang. The tank is CNC machined from aluminium in two bolted-together halves, and its low-profile design frees up room for aftermarket forced induction or other modifications.
The two internal 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 parts needed for installation with no permanent vehicle modifications.
Key Features
- Low Profile: Extra engine bay room for forced induction and other upgrades
- Swirl Deaeration: Internal swirl feature removes entrained air
- Billet Aluminium: CNC machined two-piece tank
- Complete Kit: Bracket, fittings and hoses included
- No Permanent Modifications: Bolt-in replacement for the plastic tank
