Engine Oil Pressure Sensor and/or Switch Replacement 5.0L

Tools Required

J 41712 Oil Pressure Switch Socket

1. Remove the engine cover. Refer to Engine Cover Replacement in Interior Trim.
2. Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement in Engine Controls - 5.7L.



3. Disconnect the electrical connector from the engine oil pressure gauge sensor.
4. Hold the engine oil pressure gage sensor fitting with a wrench.

Important: Note the alignment of the engine oil pressure gage sensor fitting prior to removal.

5. Remove the engine oil pressure gauge sensor using J 41712 .



6. Remove the engine oil pressure sensor fitting, if necessary.

1. Apply sealant GM P/N 12346004 (Canadian P/N 10953480) or equivalent to the threads of the engine oil pressure sensor fitting.

Important: Do not loosen the oil pressure sensor fitting after the initial torque has been obtained.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the engine oil pressure gage sensor fitting.

Tighten
Tighten the engine oil pressure gage sensor fitting to 15 N·m (15 lb in).

Important: Do not rotate the engine oil pressure sensor fitting more than 359 degrees after the initial torque has been obtained.

3. Rotate the engine oil pressure sensor fitting clockwise to the proper position (1), 50 degrees from the centerline (2).



4. Install the oil pressure sensor.
5. Hold the oil pressure sensor fitting with a wrench to prevent from turning.

Tighten
Using J 41712 tighten the oil pressure sensor to 30 N·m (22 lb ft).

6. Install the electrical connector.
7. Install the engine cover. Refer to Engine Cover Replacement in Interior Trim.
8. Install the air cleaner assembly. Refer to Air Cleaner Assembly Replacement in Engine Controls - 5.7L.
