Mishimoto Aluminum Coolant Expansion Tank for 2024-2026 Ford Mustang (2.3L) - Micro-Wrinkle Black

Fits 2024-2026 Ford Mustang Dark Horse, EcoBoost, and GT models (2.3L).

Replace the failure-prone factory plastic tank with the Mishimoto Aluminum Coolant Expansion Tank. Unlike the OE reservoir, which can yellow, crack, and leak after repeated heat cycles, this all-aluminum tank is engineered for long-term durability and performance. It features a 55% increase in coolant capacity to improve heat dissipation and maintain stable operating temperatures during spirited driving.

Inside, internal baffles prevent air from entering the cooling system during high-G maneuvers. The exterior includes a high-visibility sight glass and a stamped cold-fill line for rapid level checks without opening the system. For track enthusiasts, a dedicated overflow port allows for the installation of an NHRA-mandated overflow reservoir. This direct-fit component installs in approximately one hour using factory mounting points and the stock overflow tank cap.
