51. Remove and discard the crankshaft front seal from the front cover.





52. Remove the bolt and the idler pulley.





53. Remove the bolt and the belt tensioner.





54. CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surface. These tools cause scratches and gouges, which make leak paths. Use a plastic scraping tool to remove all traces of sealant.

Remove the bolts, studs and the front cover.
^ Discard the gaskets.





55. CAUTION: This pulse wheel is used in several different engines. Install the pulse wheel with the keyway in the slot stamped "30" or "30RFF" (orange in color).

Remove the ignition pulse wheel.





56. Install the damper bolt.





57. NOTE: LH shown, RH similar.

Remove the LH and RH spark plugs.





58. Rotate the crankshaft clockwise to position the crankshaft keyway in the 11 o'clock position and position the camshafts in the correct position. This will position the number one cylinder at top dead center (TDC).
^ Verify that the camshafts are correctly located. If not, rotate the crankshaft one additional turn and recheck.





59. Rotate the crankshaft clockwise 120 degrees to the 3 o'clock position to position the RH camshafts in the neutral position.





60. Verify that the RH camshafts are in the neutral position.





61. Remove the RH timing chain tensioner arm.
1 Remove the bolts.
2 Remove the tensioner.
3 Remove the tensioner arm.





62. Remove the bolts, RH timing chain guide and the timing chain.





63. Rotate the crankcase clockwise 60° degrees (1-2/3 turns) to position the crankcase keyway in the 11 o'clock position. This will position the LH camshafts in the neutral position.





64. Verify the LH camshafts are in the neutral position.





65. Remove the LH timing chain and tensioner arm.
1 Remove the bolts.
2 Remove the tensioner.
3 Remove the tensioner arm.





66. Remove the LH timing chain and timing chain guide.





67. Remove the damper bolt and the crankshaft sprockets.

68. CAUTION: On early build engines, the OEM pulley is pressed on 4.74 mm (0.18 inch) past flush of the end of the camshaft. On late build engines, the OEM pulley is pressed on flush to the end of the camshaft. Service pulleys on all engines are pressed on flush to the end of the camshaft.





Using the special tools, remove the coolant pump drive pulley and discard.





69. CAUTION: To make sure of correct sealing, do not scratch the camshaft.

NOTE: Early build shown, late build similar.

Using the special tools, remove the camshaft oil seal and discard.





70. NOTE: Early build shown, late build similar.

Remove the intake camshaft oil seal retainer and discard the press-in-place gasket.





71. CAUTION: Cylinder head camshaft bearing caps and cylinder heads are numbered to verify that they are assembled in their original positions. If the numbers cannot be seen, mark the camshaft bearing caps prior to removing them.

CAUTION: After loosening all of the camshaft bearing cap bolts, remove the camshaft bearing thrust caps (5R and 1R) first, or damage to the thrust caps may occur.

Loosen the bolts evenly in the sequence shown.
1 Remove the camshaft bearing thrust caps (5R and 1R).
2 Remove the remaining camshaft bearing caps.
3 Remove the camshafts from the cylinder head.

Early build vehicles





72. CAUTION: Cylinder head camshaft bearing caps are numbered to verify that they are assembled in their original positions. If the numbers cannot be seen, mark the camshaft bearing caps prior to removing them.

CAUTION: After loosening all of the camshaft bearing cap bolts, remove the camshaft bearing thrust caps (1L and 5L) first, or damage to the thrust caps may occur.

Loosen the bolts evenly in the sequence shown.
1 Remove the camshaft bearing thrust caps (1L and 5L).
2 Remove the remaining camshaft bearing caps.
3 Remove the camshafts from the cylinder head.

Late build vehicles





73. CAUTION: Cylinder head camshaft bearing caps and cylinder heads are numbered to verify that they are assembled in their original positions. If the numbers cannot be seen, mark the camshaft bearing caps prior to removing them.

CAUTION: After loosening all of the camshaft bearing cap bolts, remove the camshaft bearing thrust caps (1L and 6L) first, or damage to the thrust caps may occur.

Loosen the bolts evenly in the sequence shown.
1 Remove the camshaft bearing thrust caps (1L and 6L).
2 Remove the remaining camshaft bearing caps.
3 Remove the camshafts from the cylinder head.

All vehicles





74. CAUTION: The camshaft roller followers must be installed in their original positions.

NOTE: RH shown, LH similar.

Remove the LH and RH camshaft roller followers.
^ Mark the location of the roller followers, using a permanent-type marker.





75. NOTE: RH shown, LH similar.

Loosen the bolts in the indicated sequence and remove the LH and RH cylinder heads.
^ Discard the bolts and the gaskets.

76. NOTICE: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths.

Clean the cylinder head gasket surfaces with a plastic scraping tool and metal surface prep.

77. Support the cylinder head on a bench with the head gasket side up.





78. Remove the bolts and the oil separator cover.
^ Discard the gasket.





79. Remove the crankshaft key.
