    Stronger than Factory. The factory coolant tank, known as the grenade or football, is somewhat of an eye sore every time in the engine bay every time you pop open the hood on your S550 Mustang. If you want to completely get rid of the factory plastic two-piece tank with a much stronger unit, then look no further than the one-piece Satin Coolant Expansion Tank with Overflow Catch Can from Granatelli Motor Sports (GMS). Not only will the tank be stronger, the unique design mimics the angle and tapers of a factory engine cover to give it an OE look.

    NHRA and SCCA Legal. Best of all, this Coolant Expansion Tank is legal for NHRA and SCCA use. The tank features a built-in overflow catch can and drain petcock, so you don't have to purchase additional reservoirs or hardware.

    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 satin finish that can be polished to a bright show winning appearance.

    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 satin GMS Coolant Expansion Tank with Overflow Catch Can is specifically designed to fit on all 2015 to 2019 Mustangs, including the V6, EcoBoost, GT and Shelby GT350 models.

      Leaked after 6 months

      I installed this GMS overflow tank in late December of 2016. By June, 2017 I noticed that a very slow leak had developed at a point where 3 seams meet. Since AM only allows returns within 30 days and GMS only warranties their products for 90 days, I'm out of luck. GMS markets this as a stronger than the stock plastic so in my experience.
