Fathouse Performance S650 Coolant Tank (FP-S650-CT) - 2024-2026 Mustang S650

Upgrade your S650 engine bay with a coolant tank that’s built to last. The Fathouse Performance S650 Coolant Tank replaces the factory plastic reservoir with a clean, fabricated unit designed for better durability and a sharper OEM-plus look—perfect for daily drivers, weekend warriors, or boosted builds that demand reliable cooling hardware.

This tank mounts in the OEM location and reuses your factory coolant lines for an easy, no-hassle install. It’s engineered to work with the OEM vented coolant cap, but you can add an optional anodized billet cap if you want a more finished, high-end touch. With a smooth-radius design, lightweight construction, and tough powder-coated finish, the FP-S650-CT is a simple upgrade that adds confidence every time you pop the hood.
