Engine Oil Pressure Test: Test

If the low oil pressure indicator stays on with the engine running, check the engine oil level. If the oil level is correct:

1. Engine Oil Pressure - Test
   1. Install the oil pressure gauge (A).

   2. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem before continuing.
   3. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should be:

      Engine Oil Temperature: 176 °F (80 °C) 

      Engine Oil Pressure: 

      At Idle: 70 kPa (0.71 kgf/cm ²  , 10.1 psi) min  .

      At 3, 000 rpm: 300 kPa (3.06 kgf/cm ²  , 43.5 psi) min  .

   4. If the oil pressure is not within specifications, inspect these items:
      • Blocking of oil filter.
      • Blocking of oil strainer.
      • Inspect the oil pressure relief valve.
      • Inspect the oil pump.
   5. Remove the oil pressure gauge.
