LUBRICATION SYSTEM ON-VEHICLE INSPECTION

PROCEDURE


  1. CHECK OIL QUALITY


    1. Check the oil for deterioration, water contamination, discoloring or thinning.

      If the quality is visibly poor, replace the oil and filter Click here.

  2. INSPECT ENGINE OIL LEVEL


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

      *a Measuring Surface
      *b Low Level Mark
      *c Full Level Mark

      Check that the engine oil level is between the dipstick low level mark and full level mark.

      If the level is 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.

  3. INSPECT OIL PRESSURE


    1. Remove the oil pressure sender gauge Click here.

    2. A01WURV

      Install an oil pressure gauge with an adapter.

    3. Warm up the engine.

    4. Measure the engine oil pressure.

      Standard Oil Pressure
      Condition Specified Condition
      Idle

      70 kPa (0.7 kgf/cm2, 10.1 psi) or higher
      2500 rpm

      220 kPa (2.2 kgf/cm2, 32 psi) or higher

      If the pressure is not as specified, check the oil pump Click here.

    5. Remove the oil pressure gauge and adapter.

    6. Install the oil pressure sender gauge Click here.
