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.

      Tip:

      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 speeds or with a heavy load, (when towing, etc.), or when accelerating or decelerating frequently while driving.

      • When leaving the vehicle idling for a long time, or when driving frequently in 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 engine oil for deterioration, water intrusion, discoloration or thinning.

      If the quality is visibly poor, replace the engine oil.

  3. CHECK ENGINE OIL PRESSURE

    1. Remove the engine oil pressure switch assembly.

      CAUTION:

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

    2. A154775

      Install an oil pressure gauge.

    3. Warm up the engine.

      Tip:

      After warming up the engine, the engine coolant temperature is 75 to 100°C (167 to 212°F).

    4. Check the engine oil pressure.

      Standard Engine Oil Pressure

      At Idle

      At 3000 rpm

      25 kPa (0.3 kgf/cm2, 3.6 psi) or more

      150 to 550 kPa (1.5 to 5.6 kgf/cm2, 22 to 80 psi)

      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 oil pump.

    5. Remove the oil pressure gauge.

      CAUTION:

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

    6. Install the engine oil pressure switch assembly.
