Oil Pressure Test
NOTE:
If the oil pressure warning light stays on with the engine running, check the engine oil level. If the oil level is correct:
- Remove the oil pressure switch, and install an oil pressure gauge (A).
- Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.
- Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:
Engine Oil Temperature: 80°C(176°F)
Engine Oil Pressure:
At Idle: 70 kPa (0.7 kgf/cm 2 , 10 psi) min.
At 3,000 rpm: 300 kPa (3.1 kgf/cm 2 , 44 psi) min.
- If the oil pressure is out of specifications, inspect these items:
- Replace the oil filter (see ENGINE OIL FILTER REPLACEMENT ).
- Inspect the oil pressure relief valve (see OIL PUMP OVERHAUL ).
- Check the oil screen for clogging.
- Inspect the oil pump (see OIL PUMP INSPECTION ).
