Description

Toyota GT86 / Subaru BRZ / Scion FR-S (13-21) Mishimoto aluminium expansion tank

The Mishimoto expansion tank GT86 replaces the white plastic overflow tank of the 2013-2021 Toyota GT86, Subaru BRZ and Scion FR-S with a fully welded aluminium tank. Plastic tanks struggle with the constant switching between hot and cold, aluminium lasts far longer.

A sight tube on the side shows at a glance whether the hot and cold coolant level is right, handy before every track session or drift event. The tank works with the stock radiator and with the Mishimoto radiator and instantly gives the engine bay a cleaner look, polished or black.

Installation and delivery

Mishimoto rates installation as easy: allow less than 30 minutes. The tank goes in place of the stock overflow tank. Then top up the coolant to the correct level on the sight tube. The Mishimoto installation guide (in English) is linked below. Lead time: 4 to 7 days.

Goodbye white plastic tank: aluminium that lasts for years and shows the level.

Why choose this Mishimoto expansion tank GT86?

Heat and cold weaken the stock plastic tank over time, and it does not belong in a tidy engine bay. This fully welded aluminium tank solves both, with a sight tube as a practical extra. Choose polished or black, backed by the Mishimoto Lifetime Warranty.
