How to Install the Oil Sending Unit in a 2001 Mercury Sable

Mercurys 2001 Sable uses an oil pressure sending unit mounted in an oil galley in the engine block to detect oil pressure within the engine. The sending unit in the 3.0-liter engine is a normally-closed switch that completes the low oil pressure warning lamp circuit to ground and illuminating the lamp when there is insufficient oil pressure. When oil pressure within the galley reaches the specified pressure, the switch opens and interrupts the low oil pressure lamp ground circuit, turning the lamp off. Illumination of the low oil pressure lamp can indicate a bad sending unit, bad connection at the sending unit wire, or a more serious condition within the engine that is lowering the oil pressure.

Instructions

Overhead Valve 3.0-Liter Engine

1

Locate the oil sending unit on the rear left side of the engine block above the flywheel. Disconnect the oil sending unit electrical connector.

2

Remove the oil sending unit, using a ratchet and socket.

3

Wrap the threads on the new oil sending unit with Teflon tape, or equivalent electrically conductive sealer. Make certain the tape does not cover the end of the oil sending units sensor that penetrates the engine oil galley.

4

Thread the new oil sending unit into the engine block. Tighten the sensor to 14 foot-pounds, using a foot-pound torque wrench and socket. Connect the oil sending unit electrical connector.

5

Start the engine. Make certain the low oil pressure warning lamp on the dash instrument cluster goes off after the engine starts. Allow the engine to reach normal operating temperature and check the sending unit for leaks.

6

Park the vehicle on firm, level ground. Engage the parking brake. Raise the vehicle using a jack and support it on jack stands. Chock the rear wheels.

7

Locate the oil sending unit on the left side of the engine above the oil filter. Disconnect the oil sending unit electrical connector.

8

Hold the adapter pipe in the engine block in place using an open-end wrench. Remove the oil sending unit from the adapter pipe, using a ratchet and socket.

9

Wrap the threads on the new oil sending unit with Teflon tape, or equivalent electrically conductive sealer. Make certain the tape does not cover the end of the oil sending units sensor that penetrates the engine oil galley.

10

Thread the new oil sending unit into the adapter pipe. While holding the adapter pipe in place with the wrench, tighten the oil sending unit to 10 foot-pounds, using a foot-pound torque wrench and socket.

11

Connect the oil sending unit electrical connector.

12

Raise the Sable with the jack, and then remove jack stands. Lower the vehicle to the ground.

13

Start the engine. Make certain the low oil pressure warning lamp on the dash instrument cluster goes off after the engine starts. Allow the engine to reach normal operating temperature and check the sending unit for leaks.
