OIL PRESSURE INSPECTION [AJ]

BME011100000202

  Warning

  • Continuous exposure with USED engine oil has caused skin cancer in laboratory mice. Protect your skin by washing with soap and water immediately after this work.
  • Hot engines and the engine oil can cause severe burns. Turn off the engine and wait until it and the engine oil have cooled.

1. Remove the drive belt. (See DRIVE BELT REPLACEMENT [AJ].)

2. Remove the A/C compressor with the pipe still connected. Position the A/C compressor so that it is out of the way.

3. Remove the oil pressure switch.

4. Screw the SSTs into the oil pressure switch installation hole.

5. Install the A/C compressor.

6. Install the drive belt. (See DRIVE BELT REPLACEMENT [AJ].)

7. Warm up the engine to normal operating temperature.

8. Run the engine at the specified speed, and note the gauge readings.

  • If not within the specification, inspect for the cause and repair or replace if necessary.

  Note

  • The oil pressure can vary with oil viscosity and temperature.

Oil pressure (reference value)

  138-310 kPa {1.4-3.2 kgf/cm2, 20-45 psi} [oil temp: 100 °C {212 °F}, 1,500 rpm]

9. Stop the engine and wait until it is cool.

10. Remove the drive belt. (See DRIVE BELT REPLACEMENT [AJ].)

11. Remove the A/C compressor with the pipe still connected. Position the A/C compressor so that it is out of the way.

12. Remove the SSTs.

13. Apply silicone sealant to the oil pressure switch threads as shown in the figure.

14. Install the oil pressure switch.

Tightening torque

  12-16 N·m {1.2-1.7 kgf·m, 9-12 ft·lbf}

15. Install the A/C compressor.

16. Install the drive belt. (See DRIVE BELT REPLACEMENT [AJ].)

17. Start the engine and inspect for oil leakage.
