Removal & Installation



  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Remove the timing chain cover. Refer to Timing Chain Cover and Seal, removal & installation.
    NOTE
    The crankshaft timing mark (3) or (5) can be in one of two locations depending on whether the engine is early production (5), late production (3), or assembled with service parts (3). In all cases, the keyway (2) will always be in the 9:00 position, in line with the ladder frame mounting surface (1) when the engine is at Top Dead Center (TDC).

    Fig. The crankshaft timing mark can be in one of two locations depending on whether the engine is early production or late production or assembled with service parts. In all cases, the keyway will always be in the 9:00 position, in line with the ladder frame mounting surface when the engine is at TDC-2.0L and 2.4L engines

  4.  
  5. Verify that the engine is set to TDC.
    NOTE
    If the timing chain plated links can no longer be seen, the timing chain links corresponding to the timing marks must be marked prior to removal, if the chain is to be reused.

  6.  
  7. Mark chain link (4) corresponding to crankshaft timing mark (3) or (5).
  8.  
  9. With the engine still set to TDC, verify that the marks on the camshaft sprockets (3) are in line with the cylinder head cover sealing surface (2). If the marks do not line up, the timing chain is not correctly installed.
  10.  
  11. Mark chain link (1) corresponding to camshaft timing mark.

  17. Remove the oil pan. Refer to Oil Pan, removal & installation.
  18.  
  19. Remove the oil pump drive chain tensioner.
  20.  
  21. Remove the oil pump drive chain.
  22.  
  23. Remove the crankshaft sprocket (1).
    NOTE
    Camshaft phasers and camshaft sprockets are supplied as an assembly, do not attempt to disassemble.

  25. Remove the camshafts. Refer to Camshaft and Valve Lifters, removal & installation.
  26.  
  27. Remove the camshaft phaser (2) retaining bolt while holding the camshaft in place with a wrench (1) on the camshaft flats.
  28.  
  29. Remove the phaser (2) assembly from the camshaft.

To install:


NOTE
The camshaft sprockets and the camshaft phasers are an assembly and cannot be serviced separately.


WARNING
Do not use an impact wrench to tighten the camshaft sprocket bolts. Damage to the camshaft-to-sprocket locating dowel pin and camshaft phaser may occur.

  1. Install the phaser (2) assembly on the camshaft.
    NOTE
    Make sure the dowel is seated in the dowel hole and not in an oil feed hole. The dowel hole is larger than the 4 oil feed holes.

  2.  
  3. Install the phaser retaining bolt. Hold the camshaft in place with a wrench (1) and tighten the bolt to 44 ft. lbs. (59 Nm).
  4.  
  5. Install the camshafts. Refer to Camshaft and Valve Lifters, removal & installation.
  6.  
  7. Install the crankshaft sprocket (1) onto the crankshaft.
  8.  
  9. Install the oil pump drive chain. Verify that the oil pump is correctly timed (1, 2, 5, 6).
  10.  
  11. Reset the oil pump drive chain tensioner by pushing the plunger inward and install the Tensioner Pin 8514.
  12.  
  13. Install the oil pump drive chain tensioner (3) and tighten the bolts to 105 inch lbs. (12 Nm).
  14.  
  15. Remove the Tensioner Pin 8514 (4).

  16.  
  17. Install the oil pan. Refer to Oil Pan, removal & installation.
    NOTE
    The crankshaft timing mark (3) or (5) can be in one of two locations depending on whether the engine is early production (5), late production (3), or assembled with service parts (3). In all cases, the keyway (2) will always be in the 9:00 position, in line with the ladder frame mounting surface (1) when the engine is at TDC. Refer to illustration.

  18.  
  19. Verify that the engine is still set to TDC.
  20.  
  21. Align the camshaft timing marks (3) so they are facing each other and in line with the cylinder head cover sealing surface (2).
  22.  
  23. Install the timing chain so the plated (or marked) links on the chain align with the timing marks on the camshaft sprockets (1).
  24.  
  25. Align the timing mark on the crankshaft sprocket (3) or (5) with the plated (or marked) link (4) on the timing chain. Position the chain so the slack will be on the tensioner side. Rotate the crankshaft CLOCKWISE two complete revolutions until the crankshaft is repositioned at the TDC position with the key way at the 9 o'clock position.
    NOTE
    Keep the slack in the timing chain on the tensioner side.

  26.  
  27. Install the timing chain tensioner (5).
  28.  
  29. Verify that the timing marks on the camshafts (3) are in the proper position and in line with the cylinder head cover sealing surface. If the marks do not line up, the timing chain is not correctly installed.
  30.  
  31. Install front timing chain cover. Refer to Timing Chain Cover and Seal, removal & installation.
  32.  
  33. Connect the negative battery cable.
  34.  
  35. Operate the engine until it reaches the normal operating temperature. Check the oil and cooling systems for the correct fluid levels and check for leaks.
