OIL PRESSURE INSPECTION [MZR-CD (RF-Turbo)]

BME011114000W03

  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 engine oil can cause severe burns. Turn off the engine and wait until it and the engine oil have cooled.

1. Remove the oil pressure switch.

2. Screw the SST into the oil pressure switch installation hole.

3. Warm up the engine to normal operating temperature.

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

  • If it is less than the minimum specification, inspect for the cause and repair or replace if necessary.

Minimum oil pressure

  147 kPa {1.5 kgf/cm2, 21 psi} [1,000 rpm]
  343 kPa {3.5 kgf/cm2, 50 psi} [3,000 rpm]

  Note

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

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

6. Remove the SST.

  Caution

  • Any sealant stuck at the end of the oil pressure switch can cause operation malfunction of the oil pressure switch.
  Be sure there is no sealant at the end of the oil pressure switch.

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

8. Install the oil pressure switch.

Tightening torque

  12-17 N·m {1.2-1.8 kgf·m, 9-13 ft·lbf}

9. Install the intake manifold bracket.

10. Start the engine and inspect for oil leakage.
