This Mishimoto expansion tank replaces the stock plastic reservoir in 2015–2018 Ford Mustangs with a durable, fully-welded aluminum design.
The factory coolant tank on EcoBoost, V6, and V8 Mustangs is prone to discoloration and degradation over time. Mishimoto’s aluminum alternative not only improves the under-hood aesthetics with a clean silver finish but also delivers long-term durability and performance. Designed as a direct fit for OEM connections, it offers simple installation without the need for modifications.
Key Features:
Durable Aluminum Construction: Fully TIG-welded aluminum body resists cracking and splitting under pressure or heat.
Silver Powder-Coated Finish: Offers a sleek, clean look and additional corrosion resistance.
Direct Fit Replacement: Compatible with factory hoses, sensors, and mounting points for easy installation.
Increased Longevity Over OEM Plastic: Resists warping, staining, and failure common in stock plastic tanks.
Internal Baffles for Fluid Control: Helps reduce coolant slosh and improves fluid stability under acceleration or cornering.
Compatible with Multiple Engines: Designed to fit EcoBoost, V6, and V8 variants of the 2015–2018 Ford Mustang.
Includes Mishimoto High-Pressure Cap: Comes standard with a 21 psi cap to further raise the boiling point of coolant.
Limited Lifetime Warranty: Covered by Mishimoto’s commitment to quality and performance support.
Ideal for performance builds, track use, or simply upgrading from OEM plastic, this expansion tank delivers enhanced function and style for your Mustang’s cooling system.
