Granatelli Motor Sports Mustang Coolant Expansion Tank (2015–2026)

Your Mustang is a project and an investment—don’t leave the engine bay looking unfinished. Get rid of the factory “pumpkin” coolant tank and upgrade to a clean, chiseled, show-car quality expansion tank from Granatelli Motor Sports. This is the perfect under-hood upgrade for builders who want a premium look, durable construction, and a finished appearance that stands out at meets, shows, and on the street.

Show-Car Engine Bay Upgrade

Built from aluminum and finished in wrinkle black powder coat with the Granatelli Motor Sports logo, this coolant expansion tank delivers a sharp, modern look that instantly cleans up the front of the engine bay. It’s designed as a direct upgrade to replace the bulky OEM reservoir and give your Mustang a more aggressive, high-end presentation—exactly the kind of detail that separates a clean build from a stock-looking one.
