Description
The Mishimoto Aluminum Degas Tank (MMRT-F2D-11SN) is a direct replacement for the plastic secondary degas tank found on the 2011+ Ford 6.7L Powerstroke’s charge air cooling system. Built from aircraft-grade aluminum instead of the crack-prone factory plastic, this degas tank is engineered to handle the heat and strain that a large-displacement turbodiesel places on its secondary radiator and air-to-water intercooler circuit. A built-in sight glass and a 15.65-percent boost in coolant capacity over the stock tank set this Mishimoto part apart from the OEM component it replaces.
As part of Mishimoto’s Cooling lineup, this aluminum degas tank is designed to keep fuel and air temperatures in check on hard-working Super Duty trucks. Internal baffles hold coolant near the overflow port so aggressive driving and rough roads don’t introduce air into the coolant system, while the sight glass turns coolant-level checks into a one-step visual inspection instead of a guessing game. Because the factory secondary cooling system on the 6.7L Powerstroke is otherwise robust, upgrading just the failure-prone degas tank to durable, precision TIG-welded aluminum construction is a practical way to add long-term reliability without altering the rest of the cooling system.
