LUBRICATION SYSTEM ON-VEHICLE INSPECTION

PROCEDURE


  1. CHECK ENGINE OIL LEVEL


    1. Warm up and stop the engine, then wait for 5 minutes.

    2. Check that the engine oil level is between the low level and full level marks on the engine oil level dipstick.

      If the level is low, check for engine oil leaks and add engine oil to the full level mark.

      Note

      Do not fill to above the full level mark.

  2. CHECK ENGINE OIL QUALITY


    1. Check the engine oil for deterioration, water intrusion, discoloration or thinning.

      If the quality is visibly poor, replace the engine oil and oil filter element.

  3. INSPECT OIL PRESSURE


    1. Remove the oil pressure sender gauge assembly Click here.

      CAUTION:

      Make sure the engine is cold when removing the oil pressure sender gauge assembly to prevent burns caused by hot engine oil.

    2. A01W3FZ

      Install an oil pressure gauge with the adapter.

    3. Warm up the engine.

      Tech Tips

      After warming up the engine, the engine coolant temperature is 80°C (176°F).

    4. Measure the oil pressure.

      Standard Oil Pressure
      Engine Condition Oil Pressure
      Idling

      50 kPa (0.5 kgf/cm27.3 psi) or higher
      4000 rpm

      260 kPa (2.7 kgf/cm2, 38 psi) or higher

      If the result is not as specified, check the quality of the engine oil and check the oil paths for clogging. Repair or replace if necessary. If the engine oil pressure is still not as specified, check the timing chain cover sub-assembly.

    5. Remove the oil pressure gauge with the adapter.

      CAUTION:

      Make sure the engine is cold when removing the oil pressure gauge to prevent burns caused by hot engine oil.
