LUBRICATION SYSTEM ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT ENGINE OIL


    1. Check engine oil level.


      1. Warm up the engine, stop the engine and wait 5 minutes. The oil level should be between the dipstick's low level mark and full level mark.

        If low, check for leakage and add oil up to the full level mark.

        Note

        Do not fill engine oil above the full level mark.

        Tech Tips

        A certain amount of engine oil will be consumed while driving. In the following situations, oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals.


        • When the engine is new, for example directly after purchasing the vehicle or after replacing the engine.

        • If low quality oil or oil of an inappropriate viscosity is used.

        • When driving at high engine speed or with a heavy load, (when towing, or), when driving while accelerating or decelerating frequently.

        • When leaving the idling for a long time, or when driving frequently through heavy traffic.

        When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately.

    2. Check engine oil quality.


      1. Check the oil for deterioration, water contamination, discoloration and thinning.

        If the quality is visibly poor, replace the oil.

  2. CHECK OIL PRESSURE

    2. A01VGC3

      Install the oil pressure gauge with the adapter.

    3. Start the engine.

    4. Warm up the engine.

    5. Check the oil pressure.

      Standard
      Engine rpm Oil Pressure
      750 rpm

      30 kPa (0.3 kgf/cm2, 4.3 psi) or more
      3000 rpm

      200 kPa (2.0 kgf/cm2, 28.4 psi) or more

      If the oil pressure is not as specified, repair the lubrication system.

    6. Remove the oil pressure gauge with the adapter.

    8. Inspect for engine oil leak.
