^ Discard the gaskets, nuts and studs.
^ Inspect the exhaust manifold.





29. Remove the bolt and the oil level indicator tube.
^ Discard the O-ring seal.





30. Remove the 3 bolts and the LH exhaust manifold heat shield.





31. Remove the 8 nuts, the 8 studs and the LH exhaust manifold.
^ Discard the gaskets, nuts and studs.
^ Inspect the exhaust manifold.





32. Remove the bolts and the oil filter adapter.
^ Discard the gasket.





33. Remove the bolts, the coolant pump pulley and the 3 accessory drive belt idler pulleys.





34. Remove the bolts and the accessory drive belt tensioner.





35. Remove the coolant pump bolts.





36. Remove the coolant pump from the cylinder block.

37. Remove and discard the crankshaft pulley bolt. Using the special tool, remove the crankshaft pulley.





38. Using the special tool, remove and discard the crankshaft front seal.





39. Remove the bolts, oil pan and discard the oil pan gasket.





40. NOTE: Correct fastener location is essential for the assembly procedure. Record fastener location.

Remove the fasteners.





41. Remove the engine front cover from the cylinder block.





42. Remove the crankshaft sensor ring from the crankshaft.





43. Position the crankshaft keyway at the 12 o'clock position.





44. NOTE: If the camshaft lobes are not exactly positioned as shown, the crankshaft will require one full additional rotation to 12 o'clock.

The No. 1 cylinder camshaft exhaust lobe must be coming up on the exhaust stroke. Verify by noting the position of the 2 intake camshaft lobes and the exhaust lobe on the No. 1 cylinder.





45. CAUTION: If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into the original locations. Failure to follow these instructions may result in engine damage.

Remove only the 3 camshaft roller followers shown in the illustration from the RH cylinder head.





46. NOTE: Do not allow the valve keepers to fall off the valve or the valve may drop into the cylinder.

NOTE: It may be necessary to push the valve down while compressing the spring.

Using the special tool, remove the 3 camshaft roller followers designated in the previous step from the RH cylinder head.





47. CAUTION: If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into the original locations. Failure to follow these instructions may result in engine damage.

Remove only the 3 camshaft roller followers shown in the illustration from the LH cylinder head.





48. NOTE: Do not allow the valve keepers to fall off the valve or the valve may drop into the cylinder.

NOTE: It may be necessary to push the valve down while compressing the spring.

Using the special tool, remove the 3 camshaft roller followers designated in the previous step from the LH cylinder head.





49. CAUTION: The crankshaft cannot be moved past the 6 o'clock position once set or engine damage may occur.

Rotate the crankshaft clockwise and position the crankshaft keyway at the 6 o'clock position.





50. CAUTION: If one or both of the tensioner mounting bolts are loosened or removed, the tensioner-sealing bead must be inspected for seal integrity. If cracks, tears, separation from the tensioner body or permanent compression of the seal bead is observed, install a new tensioner. Failure to follow these instructions may result in engine damage.

Remove the bolts, the LH timing chain tensioner and tensioner arm.





51. CAUTION: If one or both of the tensioner mounting bolts are loosened or removed, the tensioner-sealing bead must be inspected for seal integrity. If cracks, tears, separation from the tensioner body or permanent compression of the seal bead is observed, install a new tensioner. Failure to follow these instructions may result in engine damage.

Remove the bolts, the RH timing chain tensioner and tensioner arm.





52. Remove the RH and LH timing chains and the crankshaft sprocket.
^ Remove the RH timing chain from the camshaft sprocket.
^ Remove the RH timing chain from the crankshaft sprocket.
^ Remove the LH timing chain from the camshaft sprocket.
^ Remove the LH timing chain and crankshaft sprocket.





53. NOTE: RH shown, LH similar.

Remove the LH and RH timing chain guides.
^ Remove the bolts.
^ Remove both timing chain guides.





54. CAUTION: Damage to the variable camshaft timing (VCT) phaser sprocket assembly will occur if mishandled or used as a lifting or leveraging device.

CAUTION: Only use hand tools to remove the variable camshaft timing (VCT) phaser sprocket assembly or damage may occur to the camshaft or VCT phaser sprocket.

Using the special tool, remove the bolt and the RH VCT phaser sprocket assembly.
^ Discard the VCT phaser sprocket bolt.
