Improve your engine bay's reliability and styling with the Mishimoto Polished Aluminum Coolant Expansion Tank. Factory plastic tanks are prone to failure over time due to constant temperature fluctuations. This Mishimoto tank is constructed from durable, TIG-welded aluminum to provide a permanent solution that withstands the rigors of high-performance driving.

The interior of the tank features precision baffles that keep coolant near the overflow ports during aggressive cornering, braking, and acceleration, preventing air from entering the cooling system. An integrated sight glass allows for immediate confirmation of hot and cold coolant levels. This tank is a direct-fit replacement that installs in under one hour, utilizes the stock expansion tank cap, and includes an overflow nipple for NHRA track legality.

  • Direct fit for 2015-2023 Ford Mustang models
  • Internal baffles prevent coolant starvation during aggressive driving
  • Integrated sight glass for easy fluid level monitoring
  • 100% TIG-welded aluminum construction for maximum durability
  • Includes overflow nipple for NHRA compliance
  • Polished finish for a clean, custom engine bay look
  • Manufacturer Part Number: MMRT-MUS-15E
  • Mishimoto Lifetime Warranty
