    Stronger than Factory. If you're tired of staring at the plain looking factory coolant tank every time you open up your hood, it may be time to add Granatelli Motor Sports (GMS) Coolant Expansion Tank to your S550 Mustang. Designed to be a direct replacement of the factory tank, this wrinkle black Coolant Expansion Tank is a one-piece design that will be much stronger than the weak factory two-piece design that can fail in high temperature situations. On top of it all, this tank features a unique tapered design that mimics the taper and angle of a factory engine cover to improve the styling under your hood.

    Quality Construction. This Coolant Expansion Tank is hand built from 6061-T6 aluminum for superior strength and styling. It features a stock style threaded neck, allowing you to re-use the factory coolant cap. The tank is completed in a wrinkle black powdercoat finish for long lasting durability and resistance against corrosion.

    Direct Fit Replacement. GMS designed this Coolant Expansion Tank to be a direct fit replacement of the factory tank. There is no modifications required for installation. 

    Application. This wrinkle black GMS Coolant Expansion Tank is specifically designed to fit on all 2015 to 2019 Mustangs, including the V6, EcoBoost, GT and Shelby GT350 models.
