Introducing the Mishimoto Coolant Expansion Tank for the 2024+ Ford Mustang GT and EcoBoost. This direct-fit solution boasts all-aluminum construction that won't yellow, crack, or leak with repeated heat cycles like the stock plastic tank will. Internal baffles prevent air entry during aggressive driving, while a 55-percent increase in coolant capacity improves heat dissipation. A high-visibility sight glass and stamped cold-fill line allow quick coolant level checks. Choose from a polished or micro-wrinkle black powder coated finish to match your style. Our expansion tank also features a coolant overflow port that allows you to install an NHRA-mandated overflow tank. This tank installs in an hour or less and is backed by the Mishimoto Lifetime Warranty to combine performance and aesthetics for a confident driving experience as long as you own your 2024+ Mustang.

Engine coolant reservoir designed to store and regulate excess coolant for proper system operation. Durable construction resists heat and pressure, helping prevent leaks and maintain optimal temperature.
