1. Detailed Steps for LS Oil Pressure Sensor Screen Removal and Installation

What are the step-by-step instructions for removing and installing the LS oil pressure sensor screen?

  1. Preparation:
  2. Disconnect the Battery: Use a 10mm wrench or socket wrench to remove the positive battery cable to prevent any electrical issues during the process.

  3. Remove Engine Cover: Pull off the plastic engine cover to access the engine components.

  4. Access the Oil Pressure Sensor:

  5. Locate the Sensor: Find the vacuum hose connected to the brake booster and follow it back to the engine. The oil pressure sensor is directly below this hose.

  6. Remove Air Box and Intake Components (if necessary): For better access, you may need to remove the air box and some intake components. Use flathead screwdrivers to undo clamps and screws.

  7. Disconnect Electrical Connector:

  8. Pull the Grey Tab: Pull back the grey tab on the electrical connector to release it from the sensor. Then, push down on the black part of the tab to remove the connector.

  9. Remove the Oil Pressure Sensor:

  10. Use Specialized Tools: Employ a 1-1/16″ 6-point deepwell socket, a 1/2″ drive universal joint, a 6″ long extension, and a 1/2″ drive ratchet. Ensure the socket has a deep inside to reach the sensor.

  11. Loosen the Sensor: Angle the setup to loosen the sensor until the ratchet stops clicking. Then, remove the ratchet, extension, universal joint, and socket in that order.

  12. Remove the Screen:

  13. Access the Screen: Once the sensor is removed, you will see the screen filter. Use a long-handled pick or similar tool to fish out the screen from the hole.

  14. Clean the Area: Clean the area around the hole to ensure no debris interferes with the new screen.

  15. Install the New Screen:

  16. Insert the New Screen: Use the pick or a small tool to insert the new screen into the hole. Ensure it is seated properly.

  17. Reinstall the Oil Pressure Sensor:

  18. Thread the New Sensor: Hand-thread the new sensor into the hole until it reaches the washers. Then, use the socket and extension to tighten it securely.
  19. Reconnect Electrical Connector: Connect the electrical connector back to the sensor by pushing it onto the tab and securing it with the grey tab.

2. Oil Pressure Gauge Installation Instructions

How do I install an oil pressure gauge with the LS oil pressure sensor?

  • Ensure Compatibility: The oil pressure gauge must be compatible with the LS engine’s oil pressure sensor. Typically, these gauges connect to the oil pressure sensor’s electrical connector or to a separate port on the engine block.
  • Wiring Configuration: Configure the wiring connection in your ECU (if applicable) to ensure the gauge receives accurate readings. Use spare AVI or SPI inputs for the oil pressure sensor.
  • Physical Installation: Mount the gauge in a visible location, ensuring it is securely fastened. Connect the gauge to the oil pressure sensor or the designated port, following the manufacturer’s instructions.

3. Information on the Oil Pressure Switch Screen

What do I need to know about the oil pressure switch screen on LS engines?

  • No Screen in Some Models: Some 6.0L LS engines did not come with a screen under the oil pressure sensor. This is a known variation and does not affect the functionality of the sensor.
  • Considerations: If your engine does not have a screen, ensure the sensor is clean and free of debris. If a screen is present, follow the steps above for removal and installation.

4. Tools Required

What tools are needed for the LS oil pressure sensor screen install?

  • 1-1/16″ 6-point deepwell socket (1/2″ drive)
  • 1/2″ drive universal joint
  • 1/2″ drive 6″ long extension
  • 1/2″ drive ratchet
  • 10mm wrench or socket wrench (for battery cable)
  • Flathead screwdrivers (for air box and intake components)
  • 24mm socket (for some models)
  • 8mm Allen wrench (for screen plug)
  • Long-handled pick or small tool (for screen removal)
  • Thread tape (for new sensor installation)

5. Ensuring Proper Torque

How do I ensure the oil pressure sensor is properly torqued?

  • Torque Specification: The exact torque specification may vary by model, but typically it is around 15-20 ft-lbs. Consult your engine manual for precise specifications.
  • Tools Needed: Use a torque wrench to ensure accurate measurement and avoid over-tightening the sensor.

6. Technical Data and Measurements

What are the specifications for the LS oil pressure sensor screen?

  • Screen Size and Type: The screen filter is usually a small, cylindrical filter that fits into the hole below the oil pressure sensor. The exact dimensions may vary, but it is typically around 1-2 inches long and 0.5-1 inch in diameter.
  • Material: The screen is usually made of a metal mesh material designed to filter debris from the oil.
