Product Description

The Perrin ASM-ENG-505RD Red Coolant Overflow Tank is a premium engine-bay upgrade designed for selected Subaru models including the WRX, WRX STI, BRZ and Toyota GR86. By replacing the stock plastic reservoir with a robust aluminium unit, you gain improved durability, enhanced visual appeal and increased clearance for aftermarket cooling or induction components.

This high-quality tank features a sleek red finish that stands out under the hood, and its compact design allows more freedom when installing upgraded intercoolers, turbo piping or other engine-bay modifications. The universal-mount hardware included means you can install it in various positions for optimal fitment and clearance.

Installation is straightforward for an experienced technician: remove the OEM reservoir, mount the new tank using the supplied brackets, connect the silicone hose, refit coolant level, and ensure secure mounting and correct routing. Fitment is confirmed for the years listed above; other makes or years should be verified manually for hose-routing, mounting location and clearance.
