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

When you're pushing your 2011-2019 Ford Fiesta hard, whether on the track or just during spirited driving, keeping your cooling system running right is key. This Mishimoto expansion tank is built to handle the demands of the Fiesta ST, offering better reliability and a cleaner look than the stock plastic tank.

The stock plastic expansion tank can become brittle over time due to constant heat cycles, but this Mishimoto tank is constructed from durable, TIG-welded aluminum. It features internal baffles that help keep coolant near the overflow port during aggressive cornering, braking, or acceleration, which prevents air from getting into your cooling system. There's also a built-in sight glass, making it easy to check your hot and cold coolant levels accurately. Plus, it's designed to fit right in under an hour and includes a nipple for adding an auxiliary coolant tank if you need to meet NHRA requirements.

This polished aluminum tank not only performs better but also looks much sharper under the hood than the factory plastic reservoir. It's designed to work with your stock expansion tank cap and comes with Mishimoto's Lifetime Warranty.
