Removal & Installation



  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Remove the A/C refrigerant using approved equipment. Refer to the Heating & Air Conditioning Section.
  4.  
  5. Remove or disconnect the following to remove the upper timing cover:

    Negative battery cable
     
    Upper torque strut bolts and set the strut aside
     
    A/C lines at the junction block near the upper timing belt cover, if equipped with a turbocharger
     
    Upper cover bolts and the cover
     

  6.  
  7. Remove or disconnect the following to remove the lower timing cover:

    Right front wheel and inner splash shield
     
    Accessory drive belts
     
    Crankshaft damper
     
    Lower torque strut
     
    Exhaust system from the manifold
     
    A/C compressor switch
     
    Upper torque strut and bracket
     
    Upper radiator support crossmember
     
    Power steering pump and bracket without disconnecting the lines
     
    Right engine mount through bolt after supporting the engine
     
    Engine support bracket
     
    Lower cover bolts and the cover
     

  8.  
  9. Rotate the crankshaft until the Top Dead Center (TDC) mark on the oil pump housing aligns with the TDC mark on the crankshaft sprocket.
  10.  
  11. Loosen the belt tensioner lock bolt.
  12.  
  13. Install an 6mm Allen wrench into the tensioner. Rotate the tensioner counterclockwise while pushing on the wrench until it slides into the locking hole.
  14.  
  15. Remove the timing belt.

  1. Set the crankshaft sprocket at TDC by aligning the sprocket with the arrow on the oil pump housing.
  2.  
  3. Set the camshafts timing marks so that the exhaust camshaft sprocket is a 1 / 2 notch below the intake camshaft sprocket.
  4.  
  5. Install the timing belt by starting at the crankshaft. Go around the water pump sprocket, idler pulley, camshaft sprockets and the tensioner.
  6.  
  7. Move the exhaust camshaft sprocket counterclockwise to align the marks and to remove any slack.
  8.  
  9. Insert a 6mm Allen wrench into the tensioner opening on the top plate of the tensioner pulley. Rotate the top plate counterclockwise. The pulley will move against the belt and the tensioner setting notch will start to move clockwise. Continue to move the top plate counterclockwise until the setting notch is aligned with the spring tang. Using the Allen wrench, to prevent the top plate from moving, tighten the tensioner lock bolt to 220 inch lbs. (25 Nm). Make sure the setting notch and spring tang are still aligned after the lock nut is tighten. If not repeat the procedure.
  10.  
  11. Remove the wrench from the belt tensioner.
    NOTE
    When repositioning the crankshaft to the TDC position, this must be done during the clockwise rotation movement. If the TDC is missed, rotate a further two full turns until TDC is reached. Do not rotate the crankshaft counterclockwise as this will result in improper tensioner settings.

  12.  
  13. Rotate the crankshaft two full revolutions and verify that the TDC marks are properly aligned.
  14.  
  15. Check the spring tang is within the tolerance window, if not repeat the previous two steps.
  16.  
  17. Install or connect the following:

    Lower timing belt cover and torque the bolts to 50 inch lbs. (6 Nm).
     
    Upper timing belt cover and torque the bolts to 50 inch lbs. (6 Nm).
     
    A/C lines at the junction block near the upper timing belt cover, if equipped with a turbocharger
     
    Right engine support bracket and reposition the power steering pump. Torque the bracket bolts to 45 ft. lbs. (61 Nm).
     
    Right engine mount through bolt and torque it to 87 ft. lbs. (118 Nm)
     
    Upper radiator support crossmember
     
    Torque strut bracket
     
    Upper torque strut
     
    A/C lines and pressure switch
     
    Exhaust system to the manifold
     
    Crankshaft damper
     
    Accessory drive belts
     
    Lower torque strut
     
    Right splash shield and wheel
     
    Negative battery cable
     

  18.  
  19. Recharge the A/C system.
  20.  
  21. Perform the camshaft/crankshaft synchronization procedure.
  22.
