Looking to add some reliable mods to your Fiesta ST?

The Mishimoto Fiesta ST expansion tank has internal baffles to prevent coolant starvation from overflow ports to engine. Also, during high speed cornering, braking, and acceleration, the internal baffles reduce coolant sloshing. The engineers at Mishimoto have also included a sight glass to allow for proper hot and cold coolant levels. The stock coolant Fiesta expansion tank is major eye sore in the engine bay, so the Mishimoto tank is offered in polished or black powder coat to keep your Fiesta ST looking great. As an added feature, you can install your tank in under one hour!
