Description
The Mishimoto Aluminum Degas Bottle (MMRT-F2D-03BK) is a direct-fit replacement expansion tank engineered specifically for the 2003-2007 Ford 6.0L Powerstroke, built to solve the chronic failures that plague the factory plastic degas reservoir. Constructed from 6061 aluminum and fully TIG-welded, this coolant bottle is finished in a durable black powdercoat and includes a sight tube for quick visual coolant checks. An added 1/8-in NPT plugged port gives you the option to install a pressure sensor down the road.
Cooling system reliability starts with components that can handle years of heat cycling, and Mishimoto designed this degas bottle to outlast the OEM plastic tank that’s prone to cracking after repeated temperature swings. The all-aluminum, TIG-welded construction is built for long-term durability under the hood, while the integrated sight tube lets you confirm hot and cold coolant levels without guesswork. Whether you’re addressing a known failure point or simply upgrading your cooling system before it fails, this expansion tank is a straightforward, bolt-in improvement over the factory piece, and it’s backed by the Mishimoto Lifetime Warranty.
