Mishimoto 2017+ Honda Civic Type R Aluminum Expansion Tank - Black

If you're pushing your 2017+ Honda Civic Type R hard, you know the engine bay gets hot and the coolant system works overtime. The stock plastic coolant expansion tank is functional for daily driving, but repeated heating and cooling cycles can lead to cracks and leaks over time. Mishimoto's aluminum expansion tank is built to handle the heat and the stress of spirited driving, offering a more reliable solution for your high-performance Civic.

This tank is fully welded from aluminum, making it much more durable than the original plastic unit. It features an internal baffle designed to keep coolant near the overflow port even during aggressive cornering or acceleration, which helps prevent air from getting into your cooling system. You'll also find a convenient sight glass so you can easily check your coolant level at a glance. The black micro-wrinkle finish looks sharp and is designed to hold up in the demanding engine bay environment.

This expansion tank is a direct fit for the 2017+ Civic Type R and includes Mishimoto's Lifetime Warranty for peace of mind.
