Mishimoto Aluminum Coolant Expansion Tank Black 15-23 Ford Mustang EcoBoost / V6 / V8 | TIG-Welded Aluminum | Coolant Overflow Tank
Overview
The Mishimoto Aluminum Coolant Expansion Tank is a direct-fit upgrade designed specifically for the 2015-2023 Ford Mustang EcoBoost, V6, and V8 models. This tank replaces the factory plastic coolant reservoir with a durable, high-quality aluminum unit that enhances both reliability and engine bay aesthetics. Ideal for Mustang owners looking to improve cooling system durability while adding a clean, performance-inspired look under the hood.
Engineered with internal baffling, this expansion tank minimizes coolant sloshing during aggressive driving maneuvers such as high-speed cornering, braking, and acceleration. The inclusion of a sight glass allows for easy monitoring of coolant levels, ensuring proper maintenance without guesswork. Mishimoto’s design philosophy focuses on combining functional improvements with visual appeal, offering a polished or anodized black finish that elevates the engine bay’s appearance while maintaining OEM-level fitment and compatibility.
Beyond aesthetics, the Mishimoto tank addresses a common failure point in Mustangs: the plastic stock expansion tanks that degrade over time due to constant thermal cycling. Constructed from TIG-welded aluminum, this tank provides superior longevity and resistance to cracking or warping. The overflow nipple on the fill neck supports the addition of a secondary coolant reservoir, making it suitable for NHRA-legal setups. For Mustang enthusiasts who demand both form and function, this tank is a practical upgrade that enhances cooling system reliability and engine bay presentation.
