The Mishimoto Aluminum Expansion Tank is an absolutely necessary upgrade for your 2015+ Mustang. Not only is the factory unit an eyesore in the otherwise gorgeous engine bay, it is also known to fail in high temperature, high performance situations. Improve your underhood styling and performance today with this piece from Mishimoto.
Fully TIG-welded for durability and crafted from high strength 100% aluminum, this black powdercoated Mishimoto Coolant Expansion Tank is much stronger than the stock two-piece plastic tank. Featuring internal baffles to keep coolant from sloshing during high speed cornering, braking or acceleration, the baffles also help to prevent coolant starvation from the overflow ports on your S550 engine.
This black Mishimoto Aluminum Coolant Expansion Tank is designed to fit on 2015-2017 V6, GT and EcoBoost Mustangs and reuses the stock overflow tank cap.
