Mishimoto 2024+ Ford Mustang V8/2.3L EcoBoost Expansion Tank - Black

When you're pushing your 2024 or 2025 Ford Mustang, whether it's the V8 or the 2.3L EcoBoost, to its limits, keeping the cooling system in check is crucial. The stock plastic coolant expansion tank can become brittle and crack over time due to repeated heat cycles, leading to leaks. This Mishimoto expansion tank is a direct-fit replacement designed to handle the demands of your Mustang.

Built from all-aluminum, this tank won't yellow, crack, or leak like the factory plastic one. It's designed with internal baffles to keep air out of the system, even during aggressive driving, which helps maintain consistent cooling performance. You'll also get a 55-percent increase in coolant capacity, meaning more heat can be dissipated effectively. A high-visibility sight glass and a stamped cold-fill line make it easy to check your coolant level at a glance. Plus, it includes an overflow port that lets you add an NHRA-mandated overflow tank if needed, and it works with the stock overflow tank cap.

This expansion tank installs in about an hour or less and comes in a micro-wrinkle black powder-coated finish to complement your engine bay. Mishimoto backs this with their Lifetime Warranty, giving you confidence in its performance and durability for as long as you own your Mustang.
