Description
The Mishimoto Aluminum Degas Tank (MMRT-F2D-08EMWBK) is a direct, fully-welded replacement for the brittle, cloudy factory plastic coolant tank found on 2008-2010 Ford 6.4L Powerstroke trucks. Finished in a stealthy micro-wrinkle black powder-coat, this all-aluminum tank features an integrated sight tube so you can finally see your coolant level at a glance instead of squinting through a fogged, aging plastic shell.
Built for the long haul, Mishimoto’s degas tank uses precision TIG-welded aluminum construction to eliminate the cracking and leaking that plagues the OEM plastic unit as it ages. Internal baffles keep coolant positioned near the overflow port during aggressive driving to help prevent air from entering the cooling system, while an additional 1/8-in NPT port makes it simple to add a sensor for pressure monitoring. It’s designed to fit with the stock cap, so upgrading doesn’t mean sourcing new hardware for that connection, and the tank is protected by Mishimoto’s Lifetime Warranty.
Vehicle Applications
