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.
