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 [...]
