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.This Part Fits:

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days.
Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Excellent quality!!!
Size: 10, Color: Ocean Breeze
Wow great quality!!! You get what you pay for that’s for sure!! The fabric is heavy-ish-indicative of quality fabric. Fit is spot on. I’m a barely size 10 (5’6” 160 lbs) and these shorts deliver!! The stretch is just perfect enough for comfort. Excited to wear these next summer!! Will watch for more sales so I can grab a couple more pairs. If you’re on the fence, get them!!
