Do you find yourself lying awake at night, horrified by visions of your swollen, plastic blob of an overflow tank? Well we're here to help you rest easy with the Mishimoto 2013-2021 BRZ / FR-S / GT86 coolant overflow tank. Stock plastic tanks are prone to failure due to repeated hot and cold cycles, and they create a horrible eyesore as they lurk in your engine bay.

Included with this 2013-2021 BRZ / FR-S / GT86 coolant overflow tank is a sight glass for easy checking of coolant levels. With the choice of two finishes, polished or anodized black, this tank will have no problem matching the style of your engine bay. This 2013-2021 BRZ / FR-S / GT86 coolant overflow tank fits perfectly with the stock or Mishimoto 2013-2021 BRZ / FR-S / GT86 radiators. As with all Mishimoto parts, this overflow tank includes the Mishimoto Lifetime Warranty.Do you find yourself lying awake at night, horrified by visions of your swollen, plastic blob of an overflow tank?

Superior Styling Over Stock Tanks

Add some reliability and engine bay styling to your vehicle with an aluminum expansion tank from Mishimoto. All Mishimoto Expansion Tanks feature internal baffles to prevent coolant starvation from overflow ports on the engine. Also, during high-speed cornering, braking, and acceleration, the internal baffles reduce coolant sloshing. The engineers at Mishimoto have included a sight tube to allow for proper observation of hot and cold coolant levels, making engine maintenance much easier.

Eventually, you’ll have to consider the health of your plastic expansion tank. Plastic is prone to failure after years of constant temperature exchange cycles. Each Mishimoto tank is constructed from durable, TIG-welded aluminum for optimal durability and longevity. All Mishimoto tanks reuse the stock expansion tank cap.
