Mishimoto Aluminum Expansion Tank for 2019+ Ram 6.7L Cummins – Black

The Mishimoto Aluminum Expansion Tank is engineered specifically for the 2019 and newer Ram 6.7L Cummins diesel engines, providing a robust upgrade over the factory plastic tank. Crafted from TIG-welded aluminum, this expansion tank offers superior durability and heat resistance, ensuring it withstands the rigors of high-temperature engine environments. Internal baffles help maintain coolant stability during demanding driving conditions, reducing the risk of air pockets that can impair your engine's cooling efficiency. The inclusion of an OEM-quality level sensor allows your vehicle's low coolant warning system to function seamlessly, maintaining safety and peace of mind without the need for additional modifications. Designed for straightforward installation, this expansion tank fits directly in place of the stock component, eliminating the need to drain the entire cooling system. All necessary provisions for factory sensors are included, making the upgrade quick and hassle-free without specialized tools. Available in a sleek black finish, the Mishimoto tank not only enhances durability but also adds a clean, finished look to your engine bay. Its surface can be customized through powder-coating, anodizing, or hydro-dipping to match your vehicle’s aesthetic preferences. Backed by Mishimoto’s lifetime warranty, this expansion tank offers a long-lasting solution to the vulnerabilities of the original plastic component, providing peace of mind and improved cooling system performance for years to come.

Features:

  • Internal baffles maintain coolant stability and prevent air pockets during high load conditions
  • Includes OEM-quality level sensor to preserve factory low coolant warning function
  • TIG-welded aluminum construction ensures durable, long-lasting performance
