Lubrication System -- On-Vehicle Inspection



1. CHECK ENGINE OIL QUALITY

  1. Check the oil for deterioration, water contamination, discoloring or thinning.
    If the quality is visibly poor, replace the engine oil and oil filter element (LandCruiser RM00000146U00EX.html).



2. CHECK ENGINE OIL LEVEL

  1. Warm up the engine and then wait for 5 minutes after turning the engine off. The oil level should be between the low level and full level marks of the dipstick.

    1. If low, check for leakage and add oil up to the full level mark.
      NOTICE:
      Do not add engine oil above the full level mark.


3. INSPECT OIL PRESSURE

  1. Remove the oil pressure switch (LandCruiser RM0000046X2005X.html).
