    CAUTION:
    • Install water pump without causing sprocket to contact timing chain. It may be necessary to adjust the timing chain until it loosens enough to install the water pump.
    • Install water pump straight in while preventing vane from contacting the engine block and timing chain case.
    • Be careful not to damage the O-rings when installing the water pump.
    • Check that timing chain and water pump sprocket are engaged.
    • Tighten water pump bolts alternately and evenly to specification.
  3. Remove dust and foreign material completely from installation area of timing chain tensioner and rear timing chain case.
  4. Turn the crankshaft pulley approximately 20° clockwise so that the timing chain on the timing chain tensioner side is loose.
