  18. After rotating the crankshaft two times in regular direction (clockwise viewed from front), confirm the timing mark.
    NOTE:
    • Always turn the crankshaft clockwise.
    • Turning the crankshaft counter clockwise before building up oil pressure in the hydraulic timing chain tensioner may result in the chain disengaging from the sprocket teeth.
  19. Install the timing chain cover.

    (refer To Timing System - "TIMING CHAIN COVER ")

    NOTE:
    • Refill Engine Oil.
    • Clean the battery posts and cable terminals with sandpaper. Assemble and then apply grease to prevent corrosion.
    • Inspect for fuel leakage.
      • After assembling the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for approximately two seconds and that the fuel line is pressurized.
      • Repeat this operation two or three times, then check for fuel leakage at any point in the fuel lines.
    • Refill Radiator and Reservoir Tank with Engine Coolant.
    • Bleed Air from the Cooling System.
      • (Refer to Cooling System - "COOLANT ")
