Fathouse Performance S550 Coolant Tank (FP-S550-CT) - 2015-2023 Mustang S550
Get rid of the flimsy factory plastic reservoir and upgrade to a coolant tank that belongs in a serious S550 engine bay. The Fathouse Performance S550 Coolant Tank is a lightweight, fabricated replacement that cleans up underhood looks while adding durability you can trust for street, track, or boosted builds.
This tank mounts in the OEM location and reuses the factory coolant lines for a straightforward install. It’s designed to work with the OEM vented coolant cap, but you can optionally step up to an anodized billet cap for an even more finished look. With a smooth-radius design and powder coated finish, the FP-S550-CT delivers an OEM-plus fit with race-ready strength. Note: 2020+ GT500 models require slight trimming of the fan shroud for clearance.
