How to Replace a Ford Oil Pump

Updated March 23, 2017

The oil pump helps to maintain proper oil pressure in your vehicle. The pump receives oil and sends it through the oil filter. A faulty oil pump can cause oil pressure to drop considerably, causing harm to your engine. All Ford vehicles use a traditional hydraulic oil pump; exact specifications will depend upon the model.

Park the vehicle on a level surface. Allow the engine to cool for at least 30 minutes prior to beginning the procedure.

Remove the oil drain plug and let the oil drain into the pan. Remove the engine oil filter.

Remove the oil pump bolts with the socket wrench. Most Ford trucks have six bolts; some Ford cars have less. Remove the oil pump, the drive gear attached to it and the oil pump O-ring. Discard the O-ring.

Lubricate the new O-ring with a small amount of clean engine oil. Attach the new O-ring, the new oil pump and the oil pump drive gear. Reattach the bolts with the torque wrench. Tighten the bolts to the specific requirement for your vehicle, usually between 70 and 100 foot-pounds of torque.

Reinstall the oil drain plug and install the new oil filter.

Fill the engine with new oil to the vehicle specifications. Ford recommends Motorcraft brand for your vehicle, the weight depends on the specific model.

Start the engine and check underneath for leaks.


Trucks usually sit up high enough to replace the oil pump without lifting the vehicle. Cars may require lifting. Lift the vehicle using a floor jack and jack stands; only lift at the recommended jacking points for your vehicle.


Tighten the bolts to within the recommended range for your specific model. Contact your local dealer or purchase a repair manual to find the specific range.
