Engineered specifically for 2011 through 2019 Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.7L Powerstroke turbo diesel engine, the Mishimoto Aluminum Primary Engine Degas Tank in Micro-Wrinkle Black (MMRT-F2D-11PMWBK) provides a permanent metallic upgrade over fragile OEM plastic reservoirs. The 6.7L Powerstroke relies on its high-temperature primary cooling loop to regulate temperatures across the engine block, cylinder heads, liquid-to-liquid oil cooler, and primary radiator.

Under demanding towing conditions and repeated high-heat duty cycles, the factory molded plastic primary degas bottle turns yellow, becomes brittle, and develops hairline stress cracks along the seams and lower coolant hose barbs. Built from robust 5052 aircraft-grade aluminum, the Mishimoto primary degas tank withstands extreme under-hood thermal swings and vibration without cracking or leaking. Finished in a subtle, clean micro-wrinkle black powder coat, it includes internal anti-aeration baffles to keep fluid concentrated at the lower feed port during hard acceleration or braking, an external clear sight glass for effortless level checks, and direct drop-in mounting tabs that secure seamlessly to the factory brackets.

Key Features & Benefits

• TIG-Welded 5052 Aircraft Aluminum: Replaces brittle factory plastic with durable aluminum to permanently eliminate seam ruptures and hose neck cracking.
• Micro-Wrinkle Black Powder Coat: Tough, textured powder-coated finish blends seamlessly into the engine bay while resisting scratches, salt corrosion, and automotive chemicals.
• Internal Anti-Aeration Baffling: Strategic internal baffles prevent coolant slosh away from the main outlet port, preventing air ingestion into the engine block during aggressive driving or steep grades.
• Built-In External Sight Glass: Integrated clear sight tube allows quick, accurate visual checks of cold and hot fluid levels without opening a hot pressurized cap.
• Direct Drop-In Bolt-On: Engineered to mount to existing factory bracket locations and connect cleanly to factory primary coolant hoses without cutting or modifications.
• Threaded for OE Caps: Direct-fit filler neck accepts the factory Motorcraft 16 PSI pressure cap or an OEM direct replacement.

• Fitment Notice: Replaces factory primary tank part numbers BC3Z-8A080-F and BC3Z-8A080-A. Dedicated strictly to the primary high-temp cooling circuit. To replace the secondary intercooler tank simultaneously, pair with Mishimoto SKU MMRT-F2D-11SMWBK (or select the complete dual kit MMRT-F2D-11KMWBK).
• Installation Tip: Inspect the lower primary radiator return hose and clamp for signs of rubber degradation prior to installation. Refill the cooling loop using a vacuum fill kit to eliminate air pockets around the cylinder heads and EGR cooler.
