Mishimoto 2014+ Ford Fiesta ST Aluminum Coolant Expansion Tank - Black

If you're looking to add some reliability and style to your 2011-2019 Ford Fiesta, this Mishimoto aluminum coolant expansion tank is a solid choice. The factory plastic tank can become a weak point over time, especially with constant temperature changes. This Mishimoto tank replaces it with a well-built, TIG-welded aluminum unit that's much more durable and looks great in the engine bay, especially in this black powder-coated finish.

What sets this tank apart is its internal baffle design. During hard cornering, braking, or acceleration, this baffle helps keep the coolant near the overflow port, preventing air from getting into your cooling system and causing potential issues. It also includes a handy sight glass, making it easy to check your hot and cold coolant levels accurately. Plus, it's designed to work with your stock expansion tank cap and even has an overflow nipple for adding an extra coolant tank if you need to meet NHRA requirements.

Installation is straightforward, typically taking under an hour, and it's designed for a perfect fit in your Fiesta ST. It comes with Mishimoto's Lifetime Warranty, so you can be confident in its longevity.
