To replace the oil pump, remove the fan shroud, upper intake, exhaust pipes, motor-mount bolts, and loosen the transmission bellhousing bolts. Lower the oil pan onto the crossmember, remove the pickup tube and screen into the pan, then remove the pan. Jacking the engine up about five inches after removing the upper intake may be needed so the pan clears the crossmember; full engine removal is another option.
The owner of a 1995 Ford F-150 4x4 extended cab with a 5.8L asked how to replace the oil pump and whether the oil pan can come out without removing the transmission. Replies describe removing the fan shroud, upper intake, exhaust, motor mounts, and loosening transmission bolts, then lowering the pan onto the crossmember and removing the pickup tube and screen. One person who did a similar job said the engine had to be raised about five inches and suggested full engine removal might be easier.
