On-Vehicle Inspection

  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 (See REPLACEMENT  ).

  2. INSPECT ENGINE OIL LEVEL 
    1. Warm up the engine, stop the engine and wait 5 minutes. The oil level should be between the 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.
  3. INSPECT OIL PRESSURE 
    1. Remove the oil pressure sender gauge (See REMOVAL  ).
    2. Install an oil pressure gauge with an adapter.
    3. Warm up the engine.
    4. Measure the engine oil pressure.
