If you’re like many 7.3L Powerstroke owners, you’ve been through more than one degas tank. 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 1999–2003 7.3L 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 glass 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. Of course, this degas tank is also backed by Mishimoto’s Lifetime Warranty.
