Mishimoto Aluminum Degas Bottle for 2008-2010 Ford F-250/F-350 (6.4L) MMRT-F2D-08EN

Fits 2008-2010 Ford F-250 and F-350 Super Duty (6.4L Powerstroke).

The factory plastic degas tank on the 6.4L Powerstroke is a known failure point. Over time, repeated heat cycles cause the OEM thermoplastic to become brittle and cloudy, leading to hairline cracks, coolant leaks, and difficulty monitoring fluid levels. The Mishimoto Aluminum Degas Bottle (MMRT-F2D-08EN) provides a permanent solution with a fully-welded, all-aluminum design that withstands high cooling system pressures and engine bay heat.

This tank features precision TIG-welding for maximum durability and includes an integrated sight tube, allowing for instant coolant level checks without the need for a flashlight. For enthusiasts looking to monitor system performance, Mishimoto has included an additional 1/8-inch NPT port for easy installation of a pressure sensor or gauge. This unit serves as a direct-fit replacement, cleaning up the engine bay while ensuring long-term reliability.
