  112.  
  113. Slacken off the center bolt.
  114.  
  115. Turn the timing gear pulley clockwise until the bolts at the oval holes are in the limit position. Continue turning clockwise until the timing gear pulley marking is 2 cogs before the marking on the upper timing cover.
    NOTE
    Do not turn counter clockwise during this procedure.

  116.  
  117. Check that the timing gear pulley is still in the limit position in the oval holes.
  118.  
  119. Tighten the center bolt in the VVT unit to 89 ft. lbs. (120 Nm). Check that the variable valve timing unit does not rotate when tightening.
  120.  
  121. Install and tighten the center plug.
  122.  
  123. Turn the variable valve timing unit clockwise to the limit position.

  126.  
  127. Tighten the timing belt tensioner center bolt. Tighten to 44 inch lbs. (5 Nm).
  128.  
  129. Install the timing belt in the following order:

    The idler pulley
     
    Intake cam
     
    Exhaust cam
     
    Water pump
     
    Tension pulley.
     

  130.  
  131. The variable valve timing unit does not have a return spring and is easily dislodged when reinstalling the timing belt. Check that the markings correspond.
    NOTE
    Adjust the timing gear pulleys so that the bolts are not at the limit positions in any of the oval holes.

  132.  
  133. This adjustment is to be made with a cold engine. A suitable temperature is approximately 68°F (20°C).
  134.  
  135. At higher temperatures (with the engine at operating temperature or a high outside temperature for example) the indicator is further to the right.
  136.  
  137. The illustration shows the position of the indicator at different engine temperatures.
  138.  
  139. Hold the center bolt secure and turn the belt tensioner eccentric clockwise until the tensioner indicator passes the marked position.
  140.  
  141. Turn the eccentric back so that the indicator reaches the marked position in the center of the window.
  142.  
  143. Remember to hold the center bolt secure at the same time.
  144.  
  145. Hold the eccentric secure and tighten the center bolt. Tighten to 18 ft. lbs. (25 Nm).
  146.  
  147. Check that the indicator is in the correct position.
  148.  
  149. Check:

    That the timing gear pulley is still in the limit position in the oval holes
     
    The timing gear pulley so that the markings line up with the upper timing cover.
     

  150.  
  151. Tighten the bolts for the timing gear pulleys.
  152.  
  153. Remove:

  154.  
  155. Install the plug with a new blind cover plug. Tighten to 30 ft. lbs. (40 Nm).
  156.  
  157. Press the timing belt to check that the indicator on the tensioner moves easily.
  158.  
  159. Position the upper timing cover.
  160.  
  161. Turn the crankshaft two turns. Check that the markings on the crankshaft timing gear pulley and the camshaft timing gear pulley match up with the markings on the oil pump and upper timing cover respectively.
  162.  
  163. Check that the indicator on the belt tensioner is within the marked position.
  164.  
  165. Remove the upper timing cover.
  166.
