The stock plastic degas tanks fitted to the 2011-2019 Ford 6.7L Powerstroke are strong when new, but it's only a matter of time before they become brittle and leak. Luckily, Mishimoto has the solution.

The Mishimoto aluminum degas tank kit for the 2011-2019 Ford 6.7L Powerstroke is the best way to ensure your degas tanks last as long as your Super Duty. This kit includes both our primary and secondary cooling system degas tanks. The fully-welded design means that these tanks are able to withstand extreme temperature swings without cracking and leaking coolant. The integrated sight glasses in both tanks make checking the coolant level easy; no more trying to shine a flashlight through a muddy tank. Our tanks also incorporate internal baffling to ensure coolant stays where it needs to be, even when the road gets rough. The Mishimoto degas tanks boast a 9.86% total increase in coolant capacity over the stock tanks to squeeze even more cooling potential under the hood.

The Mishimoto 2011-2019 6.7L Powerstroke Aluminum Degas Tank kit is available in a stealthy micro-wrinkle black powder coat or natural finish to match any custom theme. Of course, these degas tanks are also backed by Mishimoto's Lifetime Warranty. In the unlikely event that you have an issue with either tank, Mishimoto has you, and your 2011-2019 Ford 6.7L Powerstroke, covered.

* Cutting of the stock battery tray is required to remove the stock degas tank from the battery tray. Please see installation guide for cut instructions. If your stock battery tray cannot be reused, a new degas tank and battery tray can be purchased from Ford under part number: BC3Z8A080H (2011-2016) or HC3Z-8A080-D (2017-2019)

** Mishimoto does not provide powder coating, anodizing, or hydro-dipping services for this product. Customers who purchase the natural finish must source these services independently. The natural finish may show some surface imperfections that will not affect powder coating or other customization. After a few heat cycles, Mishimoto recommends checking the sight glass on the side of the degas tank to confirm proper coolant level.
