Mishimoto Aluminum Expansion Tank 19-26 Ram 6.7L Cummins
Is your factory coolant tank starting to discolor, crack, or become a weak point? The Mishimoto Aluminum Degas Tank is built to solve a very common failure point on the 6.7L Cummins: your stock plastic expansion tank. Over time, the OEM unit becomes brittle from constant heat cycles, leading to leaks or sudden failure. This upgraded Mishimoto tank replaces that weak link with a durable, high-performance solution that not only improves reliability but also adds a clean, aggressive look under the hood. With greater confidence in your cooling system, you can tow heavier, drive harder, and push your truck without worrying about coolant failures that leave you stranded.
Built for extreme durability, the Mishimoto degas tank features fully TIG-welded aluminum construction that withstands constant heat cycling and pressure without cracking or degrading over time. Internal baffles help maintain coolant stability and prevent air pockets during hard acceleration or towing, while an integrated sight glass allows quick, easy fluid level checks. It retains factory functionality with an OEM-quality level sensor and installs directly in the stock location with no modifications required. Available in multiple finishes, this tank combines long-term reliability with high-end engine bay appearance, all backed by Mishimoto’s lifetime warranty.
