How To Change Oil Pressure Sensor On 2008 Chevy Silverado?

Changing the oil pressure sensor on a 2008 Chevy Silverado is a relatively straightforward process. Here’s a complete step-by-step guide to help you through the process:

Tools and Materials:

  • New oil pressure sensor
  • Wrench or socket set (size may vary depending on your specific engine)
  • Rag or towel
  • A small amount of oil
  • Penetrating oil (optional)
  • Torque wrench (for tightening the sensor to the specified torque)


1. Prepare Your Workspace:

  • Ensure the engine is cool to the touch to avoid burns.
  • Park your Silverado on a level surface and engage the parking brake.

2. Locate the Oil Pressure Sensor:

  • The oil pressure sensor is typically located on the driver’s side of the engine block, near the oil filter. Refer to your vehicle’s service manual or consult an online resource for a more precise location.

3. Prepare for Oil Spillage:

  • Place a rag or towel under the oil pressure sensor to catch any oil that may spill during the replacement.

5. Remove the Old Oil Pressure Sensor:

  • Once loosened, unscrew the old oil pressure sensor by hand and remove it from the engine block. Be prepared for some residual oil to come out as you remove it.

6. Apply Oil to the New Sensor:

  • Apply a small amount of oil to the threads of the new oil pressure sensor. This helps create a good seal and prevents leaks.

7. Install the New Oil Pressure Sensor:

  • Screw the new oil pressure sensor into the engine block by hand. Ensure it’s threaded in correctly to prevent cross-threading.

8. Torque the New Oil Pressure Sensor:

  • Using a torque wrench, tighten the new oil pressure sensor to the specified torque based on your engine type:
    • For 4.8L and 5.3L engines, torque to 18 ft-lbs.
    • For 6.0L engines, torque to 26 ft-lbs.
  • Overtightening can damage the sensor, so be careful not to exceed the specified torque.

9. Remove the Rag or Towel:

  • Carefully remove the rag or towel from under the oil pressure sensor.

10. Check for Leaks:

  • Start the engine and check for any oil leaks around the new sensor. If you detect leaks, turn off the engine and double-check the sensor’s tightness.

11. Clean Up:

  • Wipe away any excess oil or dirt from the area around the sensor.

12. Dispose of the Old Sensor:

  • Properly dispose of the old oil pressure sensor following your local regulations for hazardous waste disposal.

That’s it! You’ve successfully replaced the oil pressure sensor on your 2008 Chevy Silverado. If you’re not comfortable performing this task yourself, it’s advisable to seek the assistance of a qualified mechanic.
