Upgrade your Ford Focus RS or ST with the Mishimoto aluminum expansion tank, designed for improved durability and engine bay aesthetics. Crafted from TIG-welded aluminum, this tank replaces the stock plastic unit prone to failure over time due to temperature fluctuations, ensuring long-lasting performance. The tank features internal baffles that prevent coolant starvation during aggressive driving, such as high-speed cornering, braking, and acceleration, by reducing coolant sloshing and maintaining proper coolant flow. A sight tube allows for easy observation of hot and cold coolant levels, simplifying maintenance and ensuring your engine runs at optimal temperature.
This Mishimoto expansion tank reuses your stock cap and includes an overflow nipple on the fill neck for adding an additional coolant tank, which keeps your Focus NHRA legal. The installation is straightforward, designed for a perfect fitment that can be completed in under one hour. The tank is available in three aesthetic options—black, wrinkle red, or wrinkle Nitrous Blue—so you can customize your engine bay's appearance to your preference. Each variant complements both the 2013-2018 Focus ST and the 2016-2018 Focus RS models, providing a seamless upgrade for enthusiasts seeking reliability and style. With Mishimoto's renowned lifetime warranty, this expansion tank offers peace of mind along with enhanced engine bay aesthetics and performance.
Whether you're upgrading for durability, improved coolant management, or aesthetic appeal, this aluminum expansion tank is an essential component for your Focus RS or ST. It helps prevent coolant overflow issues, reduces coolant sloshing during spirited driving, and makes checking coolant levels simpler, all while adding a sleek, custom look to your engine bay.
