      Stronger than Factory. Eliminate the unsightly factory coolant tank, nicknamed the “grenade” or “football”, in the engine bay of your S550 Mustang with the Coolant Expansion Tank with Overflow Catch Can from Granatelli Motor Sports (GMS). GMS designed this one-piece polished coolant tank to be much stronger than the factory plastic two-piece tank. On top of it all, the tank features a unique design that mimics the taper and angles of a factory engine cover for a custom appearance.

      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 polished to a bright mirror like appearance for impressive styling in the engine bay.

      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 polished GMS Coolant Expansion Tank with Overflow Catch Can is specifically designed to fit on all 2015 to 2020 Mustangs, including the V6, EcoBoost, GT and Shelby models.
