Engine Lubrication: Testing and Inspection
OIL PRESSURE INSPECTION1. Remove the intake manifold bracket. (FP model)
2. Remove the oil pressure switch. (ZM model)
3. Screw the SST into the oil pressure switch installation hole.
4. Warm up the engine to normal operating temperature.
5. 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
ZM: 300 - 390 kPa (3.0 - 4.0 kgf/cM2, 43 - 56 psi) [3,000 rpm]
FP: 400 - 490 kPa (4.0 - 5.0 kgf/cm2, 57 - 71 psi) [3,000 rpm]
6. Stop the engine and wait until it is cool.
7. Remove the SST
8. Apply silicone sealant to the oil pressure switch threads as shown.
9. Install the oil pressure switch.
Tightening torque: 12 - 17 Nm (1.2 - 1.8 kgf-m, 9 - 13 ft. lbs.)
10. Install the intake manifold bracket. (FP model)
11. Start the engine and inspect for oil leakage.
