S550 Mustang Coolant Expansion Tank

This Moroso S550 Coolant Expansion Tank for 2015-2016 S550 Mustang GT, EcoBoost, and V6 is a direct bolt on replacement to Ford's OE two-piece coolant tank. It allows you to run a larger amount of coolant throughout your radiator. If you are running a larger aftermarket radiator this coolant expansion tank will help to keep your S550 cooler when pushing it on the track.

Moroso's S550 Coolant Expansion Tank is fabricated from Aluminum for strength and durability under high heat situations. This coolant expansion tank uses the stock vented cap and releases pressure just like the factory tank. The neck of Moroso's S550 Coolant Expansion Tank also features a built-in overflow similar to the factory tank. In addition to better functionality, this coolant expansion tank will look way better under the hood of your S550 Mustang.
