Description
Mishimoto’s MMRT-F2D-99EMWBK degas tank was built to replace the factory plastic expansion tank on the 1999-2003 Ford 7.3L Powerstroke, a tank notorious for turning brittle and cloudy after years of heat cycles. Instead of guessing at coolant level through a hazy, cracked shell, owners get a fully-welded, all-aluminum tank with a built-in sight glass for a quick visual check. It’s a straightforward, direct-fit upgrade engineered specifically around the shortcomings of the original Ford part.
Cooling system reliability starts with a tank that won’t fail from age, and Mishimoto’s degas tank addresses that head-on. Constructed from 6061 aluminum and joined with durable TIG welds, it resists the cracking and leaking that plagues the stock plastic unit. The design also boosts coolant capacity by 43 percent over the factory tank, giving the system extra reserve, while an additional 1/8-in NPT port allows for easy sensor installation. The tank is finished to match your build, available in a natural finish ready for custom powder-coating, anodizing, or hydro-dipping, or in a Micro-Wrinkle Black powder-coated finish straight out of the box, and it retains compatibility with the stock cap for a clean, no-hassle install.
