How to Replace an Oil Pump in a Lincoln Navigator

Drive your Lincoln Navigator up onto ramps or lifts. If you use a jack, brace the front wheels so they don't roll. Set the emergency break.

Take out the timing chain and the oil pan. Remove the three bolts for the oil pump screen and take off the screen and cover.

Remove the oil pump screen and cover spacer. Undo the four oil pump mounting bolts and take the oil pump out of the engine.

Replace the old oil pump. Put the four oil pump mounting bolts on loosely then tighten them to 71 to 106 in-lb.

Reinstall the oil pump screen and cover spacer, tightening them to 15 to 22 ft-lb. Put on the oil pump screen and cover with the bolts. Tighten the bolts near the screen to 15 to 22 ft-lb and bolts at the other end of the pickup to 70 to 106 in-lb.

Put the timing chains back on and insert the oil pan. Start the Lincoln Navigator engine and check for leaks.
