LUBRICATION SYSTEM ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT OIL QUALITY


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

      If the quality is visibly poor, replace the engine oil and oil filter sub-assembly Click here.

  2. INSPECT ENGINE OIL LEVEL


    1. Warm up the engine, stop the engine and wait 5 minutes. The engine oil level should be between the engine oil level dipstick 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 engine 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 ENGINE OIL PRESSURE


    1. Using a 27 mm socket wrench, remove the oil filter cover.

    2. Remove the oil filter sub-assembly from the oil filter cover.

      *a Oil Pressure Gauge

      Set an oil filter sub-assembly in SST.

      SST
      PZ4TB-22084-23

    4. Using a 27 mm socket wrench, tighten SST.

      Torque:
      25 N*m  { 255 kgf*cm, 18 ft.*lbf }

      Note

      After tightening SST, make sure that there is no gap and that the O-ring is not protruding.

    5. Install the oil pressure gauge with SST.

    6. Warm up the engine.

    7. Measure the engine oil pressure.

      Standard Oil Pressure
      Condition Specified Condition
      Idle

      180 kPa (1.8 kgf/cm2, 26 psi) or higher
      4000 rpm

      400 to 420 kPa (4.1 to 4.3 kgf/cm2, 58 to 61 psi)

    8. Remove the oil pressure gauge.

    9. Using a 27 mm socket wrench, remove SST.
