Tools Required

J 41712 Oil Pressure Sensor Socket

1. Remove the intake manifold. Refer to Intake Manifold Replacement in Engine Mechanical - 5.7L.
2. Disconnect the oil pressure sensor electrical connector (2).

Important: Clean the area around the sensor before removal. This avoids debris from entering the engine.




3. Use J 41712 to remove the oil pressure sensor from the engine block.

1. If installing the old sensor, apply thread sealant GM U.S. P/N 12346004, Canada P/N 10953480, or equivalent.

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. Use J 41712 to install the oil pressure sensor to the engine block.

Tighten
Tighten the engine oil pressure sensor to 35 N·m (26 lb ft).




3. Connect the oil pressure sensor electrical connector (2).
4. Install the intake manifold. Refer to Intake Manifold Replacement in Engine Mechanical - 5.7L.
