Add some additional reliability and engine bay styling with the Mishimoto Ford Mustang EcoBoost, V6, V8 Aluminum Coolant Expansion Tank. The Mishimoto Coolant Expansion Tank has internal baffles to prevent coolant starvation from overflow ports to engine. Also, during high speed cornering, braking, and acceleration, the internal baffled 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 expansion tanks is major eye sore in the engine bay, so the Mishimoto Expansion Tank is offered in polished or anodized black to keep your Mustang looking great and installs in under one hour!
