Engine Lubrication: Testing and Inspection
OIL PRESSURE INSPECTIONWarning:
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.
When the engine and the oil are hot, they can cause severe burns. Turn off the engine and wait until it and oil are cool.
1. Remove the intake manifold bracket.
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 the pressure is not as specified, inspect for the cause and repair or replace as necessary.
Note:
The oil pressure can vary with oil viscosity and temperature.
Oil pressure
400 - 490 kPa (4.0 - 5.0 kg.cm2, 57 - 71 psi) [3,000 rpm]
5. Stop the engine and wait until it is cool.
6. Remove the SST.
7. Apply silicone sealant to the oil pressure switch threads as shown.
8. Install the oil pressure switch.
Tightening torque 12 - 17 Nm (1.2 - 1.8 kg.m, 9 - 13 ft. lbs.)
9. Install the intake manifold bracket. (FS model)
10. Start the engine and inspect for oil leakage.
