13. Remove the generator (1) Generator - Removal.





14. Disconnect the vacuum line (3) at the EVAP purge solenoid (1).
15. Disconnect the EVAP purge solenoid vacuum line (4) at the intake manifold and remove the vacuum line.





16. Disconnect the PCV hose from the PCV valve (1) and the intake manifold (2) and remove hose.
17. Disconnect the brake booster vacuum hose (3) and position aside.
18. Disconnect the electrical connector at the Manifold Absolute Pressure (MAP) Sensor (4).
19. Disconnect the electrical connector at the Electronic Throttle Control (ETC ) (5).
20. Disconnect the electrical connector at the Camshaft Position Sensor (CMP) (6) and position harness aside.





21. Remove the upper and lower intake manifolds (2) and insulator Intake Manifold - Removal.





22. Raise and support the vehicle Maintenance.
23. Remove the belly pan retainers (1) and remove the belly pan.
24. Drain the cooling system Service and Repair.
25. Drain the engine oil Service and Repair.





26. Disconnect the right upstream oxygen electrical sensor connector (4) from the main wire harness.
27. Loosen the lower down pipe flange bolts (3).
28. Remove the upper down pipe flange bolts (1) and position the down pipe and catalytic converter aside.





29. Remove the oil level indicator (2) retaining bolt (1) and remove the oil level indicator.





30. Remove the heater core supply tube (1) support bracket retaining bolt (2) and remove the heater core supply tube (1).





31. Disconnect the ignition coil capacitor electrical connector.
32. Remove the stud (3) and remove the upper intake manifold support bracket (2).
33. Remove the cylinder head covers, lower and upper oil pans, crankshaft vibration damper and engine timing cover Engine Timing Cover(s) - Removal.

NOTE: Take this opportunity to measure timing chain wear . Measuring Timing Chain Wear

34. Lower the vehicle.






NOTE: The left side ignition coils are shown, the right side ignition coils are similar.

35. Remove the ignition coils (2) . Ignition Coil - Removal

CAUTION: When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve and/or piston damage.

CAUTION: Always reinstall timing chains so that they maintain the same direction of rotation. Inverting a previously run chain on a previously run sprocket will result in excessive wear to both the chain and sprocket.





36. Rotate the crankshaft clockwise to place the number one piston at TDC on the exhaust stroke by aligning the dimple (4) on the crankshaft with the block/bearing cap junction (5). The left side cam phaser arrows (2) should point toward each other and be parallel to the valve cover sealing surface (3). The right side cam phaser arrows (7) should point away from each other and the scribe lines (9) should be parallel to the valve cover sealing surface (8).
37. Mark the direction of rotation on the timing chain using a paint pen or equivalent to aid in reassembly.

CAUTION: When the timing chains are removed and the cylinder heads are still installed, DO NOT rotate the camshafts or crankshaft without first locating the proper crankshaft position. Failure to do so will result in valve and/or piston damage.





38. Reset the right cam chain tensioner by pushing back the tensioner piston and installing Tensioner Pin (1).






NOTE: Minor rotation of a camshaft (a few degrees) may be required to install the camshaft phaser lock.

39. Install the RH Camshaft Phaser Lock (5).
40. Loosen both the intake oil control valve (2) and exhaust oil control valve (7).
41. Remove the RH Camshaft Phaser Lock (5).
42. Remove the oil control valve (2) from the right side intake cam phaser and pull the phaser off of the camshaft.
43. Remove the oil control valve (7) from the right side exhaust cam phaser and pull the phaser off of the camshaft.





44. Remove the right cam chain tensioner arm (6).
45. Remove two T30 bolts (4) and the right cam chain tensioner (3).
46. Remove three T30 bolts (2) and the right cam chain guide (1).





47. Remove the right camshafts Camshaft - Removal.

NOTE: If the rocker arms are to be reused, identify their positions so that they can be reassembled into their original locations.

48. Remove the rocker arms Valve Rocker Arm - Removal.

NOTE: If the hydraulic lifters are to be reused, identify their positions so that they can be reassembled into their original locations.

49. If required, remove the hydraulic lifters . Hydraulic Lifter - Removal
50. Using the sequence shown, remove the cylinder head retaining bolts.

WARNING: The multi-layered steel head gaskets have very sharp edges that could cause personal injury if not handled carefully.

CAUTION: Do not lay the cylinder head on its gasket sealing surface, due to the design of the cylinder head gasket, any distortion to the cylinder head sealing surface may prevent the gasket from properly sealing resulting in leaks.






NOTE: The head gasket (1) crimps the locating dowels (2) and the dowels may pull out of the engine block when the head gasket is removed.

51. Remove the cylinder head and gasket. Discard the gasket.





52. If required, remove the bolt (2) and the ignition coil capacitor (1).
