How to Change the Oil Pump on 2000 Ford Expedition

The oil pump used in the 2000 Ford Expedition is a sump pump inserted into the oil pan, which pushes engine oil from the pan into the engine; when the oil pump goes bad in the Ford Expedition you must pull the oil pan off to change it. The oil pump setup also means that replacing the oil filter in a 2000 Ford Expedition is more complex than in other types of vehicles.

Step 1 - Drive the Expedition onto a set of ramps and secure it using the parking brake.

Step 2 - Place a drain pan under the oil pan and remove the drain plug using a socket. Drain the oil from the pan, then replace the drain plug.

Step 3 - Remove the bolts that secure the oil pan to the bottom of the engine using a socket and ratchet. Place a metal scraper between the pan and the engine to break the seal. Pull the pan free from the engine.

Step 4 - Disconnect the wiring harness from the oil pump.

Step 5 - Loosen the jam nut that secures the oil pump to the oil pickup tube using an adjustable wrench. Thread the oil pump off the pickup tube.

Step 6 - Thread the new oil pump onto the pickup tube and secure it by tightening the jam nut with the wrench.

Step 7 - Reconnect the wiring harness to the oil pump.

Step 8 - Scrape the old gasket material off the bottom of the engine and off the mating surface of the oil pan using a metal scraper.

Step 9 - Place the new gasket onto the oil pan and place the oil pan against the engine.

Step 10 - Thread the bolts into the oil pan and tighten them in an alternating fashion from side to side using the socket and ratchet.

Remove the oil filler cap from the driver's side valve cover, place a funnel into the valve cover and drain 4 qt. of motor oil into the valve cover. Close the cap.
