Removal & Installation



3.3L & 3.8L Engines
  1. Before servicing the vehicle, refer to the Precautions Section.
    NOTE
    Use fender covers to avoid damaging painted surfaces.


    NOTE
    To avoid damage, unplug the wiring connectors carefully while holding the connector portion.


    NOTE
    Mark all wiring and hoses to avoid misconnection.


    NOTE
    Turn the crankshaft pulley so that the No. 1 piston is at Top Dead Center (TDC).

  2.  
  3. Disconnect the negative terminal from the battery.
  4.  
  5. Remove the timing chain cover. Refer to Timing Chain Cover and Seal, removal & installation.
    NOTE
    Before removing the timing chain, mark the RH/LH timing chain with an identification based on the location of the sprocket as the identification mark on the chain for the TDC can be erased accidentally.

To install:

  1. Check the camshaft sprocket and crankshaft sprocket for abnormal wear, cracks, or damage. Replace as necessary.
  2.  
  3. Inspect the tensioner arm and chain guide for abnormal wear, cracks, or damage. Replace as necessary.
  4.  
  5. Check that the tensioner piston moves smoothly when the ratchet pawl is released.
  6.  
  7. Install the jack to the upper oil pan.
  8.  
  9. The key of crankshaft must be aligned with the timing mark of timing chain cover. Then, piston of No. 1 cylinder is placed at the TDC on the compression stroke.
  10.  
  11. Install the tensioner adapter assembly.
  12.  
  13. Install the crankshaft sprocket.
  14.  
  15. Install the LH timing chain guide. Tighten to 14-18 ft. lbs. (20-25 Nm).
  16.  
  17. Install the LH timing chain.
    1. To install the timing chain with no slack between the camshaft and crankshaft, use the following procedure.
    2.  
    3. Place the crankshaft sprocket on first, then the timing chain guide, then the exhaust camshaft sprocket, and finally the intake camshaft sprocket.
    4.  
    5. The timing mark of each sprockets should be matched with the timing mark (color link) of the timing chain when installing the timing chain.
    6.  

  18.  
  19. Install the LH timing chain tensioner arm. Tighten to 14-16 ft. lbs. (19-22 Nm).
  20.  
  21. Install the chain tensioner. Tighten to 87-104 inch lbs. (10-12 Nm).
  22.  
  23. Install the LH cam-to-cam guide. Tighten to 87-104 inch lbs. (10-12 Nm).
  24.  
  25. Install the crankshaft sprocket.
  26.  
  27. Install the oil pump chain and the oil pump sprocket. Tighten to 14-16 ft. lbs. (19-22 Nm).
  28.  
  29. Install the RH timing chain guide. Tighten to 14-18 ft. lbs. (20-25 Nm).
  30.  
  31. Install the RH timing chain.
    1. To install the timing chain with no slack between the camshaft and the crankshaft, use the following procedure.
    2.  
    3. Place the chain on the crankshaft sprocket first, then the intake camshaft sprocket, then the exhaust camshaft sprocket.
    4.  
    5. The timing mark of each of the sprockets must be matched with the timing mark (color link) of timing chain when installing the timing chain.
