Engineered specifically for 2017 through 2019 Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.7L Powerstroke V8 turbo diesel engine, the Genuine Ford Primary Engine Water Pump Assembly (Part # HC3Z-8501-A / Motorcraft PW-571) restores cooling performance to the engine's primary high-temperature cooling loop. The 6.7L Powerstroke diesel platform utilizes a dual-cooling system: a secondary low-temperature loop for the charge air cooler, fuel cooler, and transmission, and a primary high-temperature circuit dedicated to cooling the engine block, cylinder heads, engine oil cooler, and turbocharger.

Over extended mileage and heavy towing duty cycles, mechanical water pumps experience shaft bearing play, shaft seal weeping from the weep hole, or impeller cavitation erosion. When the primary water pump fails or seeps coolant, the engine quickly suffers from overheating under load, low coolant warnings, and serpentine belt contamination. Built to strict Ford engineering standards, this genuine OEM assembly includes a factory-installed drive pulley and high-temp rubber perimeter gasket, guaranteeing proper belt alignment and a leak-free seal directly out of the box with zero core charge.

• Fits Model Years: 2017, 2018, 2019
• Cooling Loop Verification: Fits the Primary (High-Temp) Cooling Circuit only. Note: Does not fit or replace the Secondary (Low-Temp) coolant pump located lower on the front timing assembly.
• Year Split Notice: Designed specifically for 2017–2019 6.7L Powerstroke engines. (For 2011–2016 model years, use primary pump SKU BC3Z-8501-F / Motorcraft PW-497; for 2020+ models, verify revision LC3Z-8501-A).
• Installation Tip: Clean the front timing cover mating surface thoroughly with a plastic scraper and solvent before installing the new pump and gasket. Torque water pump housing bolts in an alternating star pattern to factory Ford specifications (89 in-lbs / 10 Nm) to avoid uneven gasket compression. Vacuum-fill the primary cooling system with Ford Motorcraft Yellow Antifreeze/Coolant (WSS-M97B57-A2) to eliminate trapped air pockets around the EGR cooler and turbocharger bearing housing.
