An old plastic coolant reservoir or expansion tank will eventually wear out and crack. These premium Mishimoto coolant reservoir overflow and expansion tanks are made of aluminum, ensuring that it will not crack over time.

The reservoir / overflow tanks are compact and thus takes up very little horizontal engine bay space. Each Universal kit includes mounting bracket, hose, and hardware and can hold up to 850cc (28 fl oz) of fluid, and are available in multiple colors too! Both Universal and non-Universal reservoir / overflow tanks are perfect for improving your engine bay's looks, saving space, and preventing leaks!

The application-specific expansion tanks are perfect to replace the stock plastic expansion tanks. They are 100% direct-fit and will last forever, in addition to giving your engine bay a much sportier appearance! Some expansion tank applications even feature an internal baffle that keeps coolant near the overflow port during aggressive driving, preventing air entry into coolant system.

All kits include a high pressure radiator cap and installation hardware (hose, clamps, bracket, etc) as applicable.
