The Ford Motorcraft YC3Z-6675-A (F81Z-6675-AA) is the genuine OEM replacement engine oil pan engineered specifically for 1994–2003 Ford F-250, F-350, F-450, and F-550 Super Duty and OBS trucks, 2000–2003 Ford Excursions, and 1994.5–2003 Ford E-Series vans equipped with the 7.3L Powerstroke diesel engine. Manufactured directly to original Ford engineering tolerances, this stamped steel pan guarantees exact factory fitment around the engine crossmember, steering linkage, and starter motor clearance zones. Each pan comes finished from the factory in a durable, electrostatic black e-coat paint, features an integrated internal anti-slosh baffle to maintain oil supply at the pickup tube under hard braking and steep operating angles, and includes a pre-installed factory drain plug.

Chronic oil leaks from exterior rust perforations, structural metal rot along the sump bowl and lower side rails, leaking dipstick adapter threads, and stripped factory drain plug ports are what this original equipment pan eliminates. In states that use salt or brine on winter roads, factory 7.3L oil pans are famous for rusting through from the outside inward, eventually leaking 15 quarts of oil onto the driveway or roadway. Because replacing a 7.3L oil pan requires lifting or pulling the engine, installing the genuine Ford YC3Z-6675-A pan ensures that bolt hole alignment, flange flatness, dipstick adapter bung threads, and crossmember clearances match the block. It is an authentic Ford replacement bare oil pan with a pre-installed drain plug; oil pan sealant (Motorcraft TA-31 high-torque silicone), dipstick adapter flange kits, and oil pickup tubes are sold separately.

It fits all 1994–1997 Ford OBS and 1999–2003 Ford Super Duty F-250, F-350, F-450, and F-550 trucks, 2000–2003 Ford Excursions, and 1994.5–2003 Ford E-250, E-350, and E-450 Econoline vans equipped with the 7.3L Powerstroke turbo diesel engine (rear sump configuration).

Due to the front engine crossmember sitting directly below the sump on 7.3L chassis, safely lift the engine out of the vehicle using a heavy-duty shop crane and engine stand, or unbolt the transmission crossmember and motor mounts to hoist the engine several inches upward off the frame pads. Once the engine is secured, unthread the oil drain plug and drain all remaining engine oil completely into a suitable container. Remove the outer nut on the oil dipstick adapter located on the side of the pan and allow the inner adapter body to drop into the pan cavity (or use an external dipstick repair adapter on reassembly). Remove the perimeter oil pan mounting bolts, insert a gasket separator or thin putty knife between the pan flange and block to cut through the factory silicone seal, and remove the rusted pan. Thoroughly scrape all old silicone sealant from the engine block rails, front cover base, and rear main seal carrier, then degrease the mating surfaces using brake cleaner until completely bare and oil-free. Lay down a continuous, uniform 1/4-inch bead of Motorcraft TA-31 diesel RTV silicone around the entire pan flange, ensuring the bead runs around the inside of each bolt hole. Place the new Ford pan onto the crankcase, loosely secure all perimeter bolts, and torque them in a crisscross sequence starting from the center out to 15 ft-lbs (180 in-lbs). Allow the sealant to cure fully for 24 hours before filling the engine with 15 quarts of 15W-40 oil and checking for leaks on initial startup.
