Mishimoto 11+ Ford 6.7L Powerstroke Secondary Expansion Tank - Natural

The 2011+ Ford 6.7L 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 that propels the 2011+ F-250 and F-350 is robust and reliable, but it's not without its weaknesses. Like any large-displacement turbodiesel, the 6.7L generates an immense amount of heat and strain on the charge air cooling system. Luckily, the engineers at Ford fitted the Super Duty with a robust secondary cooling system that's dedicated to keeping fuel and air temps in check. While the secondary radiator and air-to-water intercooler are cut from the same cloth as the heavy-duty 6.7L, the degas tank that supplies them both with coolant is not quite as durable.Anybody who has worked on an aging cooling system knows that anything plastic tends to crack and shatter with time. The 6.7L Powerstroke's secondary cooling system degas tank is no exception, which is why Mishimoto has designed an all-aluminum replacement.Our secondary degas tank for the 2011+ Ford 6.7L Powerstroke ditches the plastic construction in favor of aircraft-grade aluminum that's as durable and hard-wearing as the rest of your Super Duty. Like the stock tank, our degas tank includes internal baffles to keep the coolant around the outlet and prevent aeration, no matter how rough the road gets. The Mishimoto secondary degas tank also features a 15.65-percent greater coolant capacity than the stock tank to add even more cooling potential to your 6.7L's secondary cooling system. The side of this degas tank also features a sight glass to make checking the coolant level a one-step operation.This all-aluminum secondary degas tank for the 2011+ Ford 6.7L Powerstroke is available in a natural aluminum finish or micro-wrinkle black powder coat and is built to last. We're so confident in our degas tank that we've backed it with our Mishimoto Lifetime Warranty for a lifetime of worry-free cooling.
