Product Description

The Perrin ASM-ENG-505HP Coolant Overflow Tank replaces the fragile OEM plastic reservoir with a lightweight aluminum unit finished in Perrin's signature Hyper Pink powdercoat. The compact design frees up engine bay clearance for aftermarket intercooler piping and boost tubes, making it a natural fit for any turbocharged Subaru build. It uses the factory OEM coolant cap for a clean, stock-style seal while holding more coolant than the previous design for improved system reserve.

Installation is straightforward - the kit includes universal mounting brackets and 3 feet of silicone hose for flexible positioning, and the tank can be mounted virtually anywhere in the engine bay. Compatible across a wide range of Subaru, Scion, and Toyota platforms from 2002 through 2025, it is also available in Black (ASM-ENG-505BK) and Red (ASM-ENG-505RD) to match your build's color scheme.
