Function Inspection

  1. Engine oil level check
    1. Park the vehicle on a level surface.
    2. Remove the oil level gauge and wipe away the oil.
    3. Reinsert the oil level gauge all the way. Be sure that the oil level gauge is correctly inserted and properly orientated.
    4. Pull out the oil level gauge again, and check both sides of the oil level gauge. Use a lower side to determine the engine oil level. If the engine oil level is below the L mark, check the engine for oil leakage and refill the oil to bring the level up to the F mark.
    5. Start the engine to circulate the oil in the engine.
    6. Five minutes after stopping the engine, check that the engine oil level is between the L and F marks of oil level gauge. If the oil level is low, check for oil leakage and refill the oil up to the F mark.
      NOTE:
      • To prevent overfilling of the engine oil, do not refill the oil above the F mark when the engine is cold.
      • As the oil level gauge is used for daily maintenance, the F and L marks are set assuming that the engine is cold.

  2. Engine oil quality check
    1. Check the oil for degradation, mixture of moisture, discoloration and dilution. Replace the oil when its quality has deteriorated clearly.
  3. Oil pressure check
    CAUTION: Wash the equipment and hoses before and after measurement.
    1. Remove the engine oil pressure switch assembly. (Refer to ENGINE OIL PRESSURE SWITCH ASSEMBLY (FA20)  )
    2. Install the oil pressure gauge using the adapter.

    3. Install the air cleaner case sub-assembly. (Refer to ON-VEHICLE INSPECTION )
    4. Warm up the engine.
    5. Measure the oil pressure.

      Standard value:

      Engine Speed Oil temperature Oil pressure
      Idle speed (no load, and for AT model, select lever in "P" or "N" range, for MT model, gear shift lever in neutral position) 80°C {176°F} 50 kPa {0.5 kgf/cm2 , 7.3 psi} or more
      3,000 r/min 80°C {176°F} 222 kPa {2.3 kgf/cm2 , 32 psi} or more
    6. Remove the air cleaner case sub-assembly. (Refer to V-BELT (FA20) )
    7. Remove the oil pressure gauge.
    8. Install the engine oil pressure switch assembly (Refer to ENGINE OIL PRESSURE SWITCH ASSEMBLY (FA20)  )
