PRODUCT DESCRIPTION
Add reliability and style to your engine bay with the Mishimoto Mustang V6, V8, and EcoBoost Expansion Tank. This tank features internal baffles that prevent coolant starvation at the overflow ports. Furthermore, during high-speed cornering, braking, and acceleration, the internal baffles reduce coolant sloshing. Mishimoto engineers also included a sight tube for checking proper hot and cold coolant levels. The stock Mustang expansion tank is an eyesore in the engine bay, so the Mishimoto tank is offered in polished or anodized black to keep your Mustang looking pristine. Plus, you can install it in under an hour! This Mustang expansion tank is designed to work with the stock expansion tank cap and includes an overflow nipple on the filler neck to add an additional coolant reservoir to keep your Mustang NHRA compliant. Plastic expansion tanks are prone to failure after years of constant temperature variations, so the Mishimoto tank is constructed from durable, TIG-welded aluminum for optimal durability and longevity. The Mishimoto Mustang V6, V8, and EcoBoost Expansion Tank is engineered for a perfect fit in the 2015 Mustang and, like all of our 2015 Mustang parts, includes the Mishimoto Lifetime Warranty. Direct fit for the 2015+ Ford Mustang EcoBoost, V6, and V8. Internal baffles keep coolant near the overflow port during aggressive driving. Sight tube allows for checking proper hot and cold coolant levels. 100% aluminum construction, fully TIG-welded for maximum durability. Mishimoto Lifetime Warranty.
