Product Details

The stock plastic degas tank on your 2011-2022 Ford 6.7L Powerstroke can become brittle over time, leading to cracks and leaks. Mishimoto has developed an all-aluminum replacement that's built to handle the heat and strain of your Super Duty's robust secondary cooling system. This tank is designed to keep your fuel and air temperatures in check, especially under heavy use.

Crafted from aircraft-grade aluminum with precision TIG welds, this expansion tank is much more durable than the original plastic component. It includes internal baffles, just like the stock tank, to keep coolant around the outlet and prevent air from entering the system, even on rough terrain. You'll also get a notable 15.65% increase in coolant capacity, which can help improve cooling performance. Plus, a built-in sight glass makes checking your coolant level a simple, one-step process.

This tank is available in a natural aluminum finish and is backed by Mishimoto's Lifetime Warranty, giving you peace of mind for years to come.
