Product Details

This is the Moroso 63814 coolant expansion tank, a direct bolt-in replacement specifically for the 2003-2012 Mazda RX-8. If your original plastic tank is cracked, leaking, or has become brittle with age, this unit from Moroso is designed to get your cooling system back in reliable working order. It handles the same job as the factory tank, holding excess coolant and allowing it to expand and contract with temperature changes, while also providing a reservoir for the system.

Moroso builds this expansion tank from durable aluminum, which is a strong upgrade over the original plastic component. Aluminum is less prone to cracking from heat cycles and physical stress. The design is a direct replacement, meaning it uses the factory mounting points and hose connections, simplifying the installation process. This makes it a solid option for RX-8 owners looking to replace a failing coolant reservoir with a more robust part.
