    NOTE
    If the timing belt is to be reused, draw an arrow indicating the direction of rotation on the back of the belt for reinstallation.



    Negative battery cable
     
    Alternator
     
    Accessory drive belts
     
    Crankshaft bolt and pulley using Crankshaft Holding Tools MB990767 and MB998754/MD998715
     
    Heated oxygen sensor connection, if necessary
     
    Power steering pump (leaving the hose attached) and position it aside
     
    Power steering pump bracket
     
    Tensioner pulley assembly
     
    Upper right front timing belt cover
     
    Upper left front timing belt cover
     

  10.  
  11. Align the timing marks by turning the crankshaft with MD998769 Crankshaft Turning tool.
  12.  
  13. Loosen the center bolt on the timing belt tensioner pulley and remove the belt.
    WARNING
    Do not rotate the crankshaft or camshaft after removing the timing belt or valvetrain components may be damaged. Always align the timing marks before removing the timing belt.

  14.  
  15. Remove the retaining bolts and remove the timing belt tensioner. When the timing belt tensioner is removed from the engine, it is necessary to compress the plunger into the tensioner body.
  16.  
  17. Place the tensioner in a vise and slowly compress the plunger. Take care not to damage the pushrod. If there is a plug at the end of the tensioner, place a plain washer over the plug to protect it from damage while compressing.
    NOTE
    Position the tensioner perpendicular to the vise jaws, taking care to insert the pin so it can still be removed after the tensioner is installed on the engine.

  18.  
  19. When the plunger is compressed into the tensioner body, install a pin through the body and plunger to hold the plunger in place until the tensioner is installed.

To install:

  1. Slip the crankshaft damper onto the crankshaft and torque the bolt to 137 ft. lbs. (185 Nm)
  2.  
  3. Install the timing belt tensioner and tighten the retaining bolts to 17 ft. lbs. (24 Nm), but do not remove the pin at this time.
  4.  
  5. Check that all timing marks are still aligned.
  6.  
  7. Use bulldog clips (large paper binder clips) or other suitable tool to secure the timing belt and to prevent it from slacking. Install the timing belt. Starting at the crankshaft, go around the idler pulley, then the front camshaft sprocket, the water pump pulley, the rear camshaft sprocket and the tensioner pulley.
  8.  
  9. Be sure the belt is tight between the crankshaft and front camshaft sprocket, between the camshaft sprockets and the water pump. Gently push the tensioner pulley into the timing belt so that it does not sag, and temporarily tighten the center bolt.
  10.  
  11. Move the crankshaft 1 / 4 turn counterclockwise, then turn it clockwise to the position where the timing marks are aligned.
  12.  
  13. Loosen the center bolt of the tensioner pulley. Using MD998767 tensioner tool, and a torque wrench apply 3.3 ft. lbs. (4.4 Nm) tensional torque to the timing belt and tighten the center bolt to 35 ft. lbs. (48 Nm). When tightening the bolt, be sure that the tensioner pulley shaft does not rotate with the bolt.
  14.  
  15. Remove the tensioner plunger pin.
  16.  
  17. Check that the tensioner pushrod is within the standard value. When the tensioner is engaged the pushrod should measure 0.149-0.177 in. (3.8-4.5mm).
  18.  
  19. Rotate the crankshaft two revolutions and check the timing marks. If the timing marks are not properly aligned remove the belt and repeat the installation steps.
  20.  
  21. Install or connect the following:

    Timing belt covers
     
    Engine mounting bracket
     

  22.  
  23. Lower the engine enough to install the engine mount onto bracket and remove the floor jack.

    Power steering pump bracket and pump
     
    Crankshaft pulley and tighten the retaining bolt to 137 ft. lbs. (185 Nm)
     
    Accessory drive belts
     

  24.  
  25. Properly fill the cooling system.
  26.  
  27. Connect the negative battery cable.
  28.  
  29. Check for leaks and proper engine and cooling system operation.
