It’s been almost a decade since the first 2008–2010 Ford 6.4L Powerstroke rolled off the assembly line. A lot can happen to a vehicle in that much time. And, if you’re like many 6.4L Powerstroke owners, your degas tank is looking worse for wear. Over time, the stock plastic tank becomes brittle and cloudy, making it prone to leaks and impossible to see the coolant level. Luckily, Mishimoto has a solution that will look and function in 15 years just as well as it does today.

Replace your ugly and brittle plastic stock tank with Mishimoto’s all-aluminum 2008–2010 Ford 6.4L Powerstroke degas tank.

The fully-welded design of Mishimoto’s degas tank means that it won’t crack and leak coolant, and the integrated sight tube makes checking the coolant level easy. No more trying to shine a flashlight through a muddy tank.

For even more convenience, the Mishimoto degas tank includes an additional 1/8” NPT port for easy pressure monitoring. The Mishimoto 6.4L Powerstroke Aluminum Degas Tank is available in a stealthy micro-wrinkle black powder coating or natural finish*2 to match any custom theme. Of course, this degas tank is also backed by Mishimoto's Lifetime Warranty. In the unlikely event you have an issue, Mishimoto has you, and your 2008–2010 Ford 6.4L Powerstroke, covered.
