The 2011-2019 Ford Super Duty is a workhorse of a truck and the go-to pickup for many of the hardest working people on Earth. The 6.7L Powerstroke propelling the 2011-2019 F-250 and F-350 is robust and reliable, but it's not without its weaknesses. Like any large-displacement diesel, the 6.7L generates an immense amount of heat and strain on the cooling system. Luckily, the Super Duty's radiator is robust enough to get the job done, but some of its supporting components aren't so robust, specifically the primary cooling system's degas tank.Like many manufacturers, Ford incorporates plastic into many of their engine components, including the degas tank. This plastic primary degas tank is strong when it's new, but with repeated heat cycles, it can become brittle and cause leaks. The solution to this is to ditch the plastic altogether.The Mishimoto 2011-2019 Ford 6.7L Powerstroke aluminum primary degas tank is the best way to ensure that your degas tank lasts as long as your Super Duty. The fully-welded design of Mishimoto's degas tank means that it won't crack and leak coolant, and the integrated sight glass makes checking the coolant level easy
