    Tighten the slide bolt to 14 ft. lbs. (18 Nm).
     
    Tighten the pivot bolt to 14 ft. lbs. (18 Nm).
     

  24.  
  25. Verify the timing marks are still in alignment.
  26.  
  27. Rotate the crankshaft one full turn and line up the center of the three lines on the flywheel with the housing mark.
  28.  
  29. Align the right side camshaft sprocket timing mark with the notch in the cover.
  30.  
  31. Attach the timing belt to the crankshaft sprocket and camshaft sprocket. Avoid slackening the belt on the upper side.
  32.  
  33. Loosen the tensioner mounting bolts 1/2 turn and allow the tensioner to contact the belt.
  34.  
  35. Push on the belt by hand to ensure smooth tensioner operation.
  36.  
  37. Apply torque to the camshaft sprocket in the counterclockwise direction using a belt tension wrench. While applying the torque tighten the tensioner mounting bolts temporarily.

    Tighten the slide bolt to 14 ft. lbs. (18 Nm).
     
    Tighten the pivot bolt to 14 ft. lbs. (18 Nm).
     

  38.  
  39. Verify the timing marks are still in alignment.
  40.  
  41. Remove the crankshaft pulley.
  42.  
  43. Install the timing belt covers.
  44.  
  45. Install the crankshaft pulley.
  46.  
  47. Connect the negative battery cable.

  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Remove the timing belt covers.
  6.  
  7. Matchmark the timing belt to the sprocket, cover and block marks as follows:
    1. Turn the crankshaft to align the timing marks on the crankshaft sprocket with the mark on the block.
    2.  
    3. With the crankshaft marks aligned make sure the left and right camshaft sprocket marks are lined up with marks on the timing covers.
    4.  
    5. If all the marks are in line, use white paint to mark the direction of rotation of the belt as well as mark the spots on the belt where it crosses over the timing marks on the pulleys.
    6.
