Engineered specifically for 2011 through 2016 Ford F-250, F-350, F-450, and F-550 Super Duty trucks (as well as 2016 F-650 and F-750 commercial chassis) equipped with the 6.7L Powerstroke V8 turbo diesel engine, the Alliant Power Primary Engine Water Pump (Part # AP63507) provides an OEM-grade direct replacement for the engine's high-temperature cooling loop. In the 6.7L Powerstroke thermal management system, this mechanical upper water pump circulates high-temp engine coolant across the engine block, cylinder heads, engine oil cooler, and primary EGR cooler circuit.

Under heavy hauling and severe duty cycles, mechanical water pumps experience shaft runout, bearing looseness, and weep-hole dripping from the ceramic face seal. Operating a leaking or worn primary water pump risks high cylinder head temperatures, low coolant warnings, and belt slippage. Manufactured to meet or exceed original equipment performance standards, the Alliant Power AP63507 features corrosion-resistant cast aluminum housing, a factory-aligned pressed drive pulley, and an OEM channel-fit perimeter gasket, replacing Ford OEM part numbers BC3Z-8501-A, BC3Z-8501-F, and Motorcraft PW-502 / PW-497 with zero core charge.

• Fits Model Years: 2011, 2012, 2013, 2014, 2015, 2016
• Platform Generation Split Notice: Fits 2011–2016 first-gen front timing covers only. (For 2017–2019 engines, use primary pump SKU HC3Z-8501-A; for 2020–2026 engines, use SKU LC3Z-8501-B).
• Cooling Circuit Verification: Fits the Primary (High-Temperature) Engine Cooling Circuit only. (For the auxiliary low-temperature circuit pump, use Alliant Power SKU AP63505 or Ford BC3Z-8501-C).
• Installation Tip: Clean all corrosion and residual gasket material from the front timing cover mounting channel before positioning the new gasket dry. Snug housing bolts in an alternating star pattern to factory Ford specification (89 in-lbs / 10 Nm) to avoid uneven gasket compression. Vacuum-fill the cooling system using Motorcraft Yellow Antifreeze/Coolant (WSS-M97B57-A2) to purge air from the turbocharger and EGR cooler lines.
