Right Cylinder Head

RIGHT

Special Tools:











CAUTION: The magnetic timing wheels (1) must not come in contact with magnets (pickup tools, trays, etc.) or any other strong magnetic field. This will destroy the timing wheels ability to correctly relay camshaft position to the camshaft position sensor.






1. Perform the fuel pressure release procedure Service and Repair.
2. Disconnect and isolate the negative battery cable.
3. Raise and support the vehicle Maintenance.
4. Remove the belly pan.
5. Drain the cooling system Service and Repair.
6. Drain the engine oil Service and Repair.





7. Lower the vehicle.
8. Remove the engine cover (1).
9. Recover the refrigerant from the refrigerant system Refrigerant System Recovery.





10. Remove the air cleaner body (1) Air Cleaner Body - Removal.





11. Remove the resonator (1) Removal.





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





13. Remove the accessory drive belt (7) Serpentine Accessory Drive Belt - Removal.





14. Remove three bolts (2) and the power steering pump heat shield (1).





15. Disengage the wire harness retainer (2) from the power steering pump.
16. Remove three bolts (1) and reposition the power steering pump and bracket as an assembly. Do not disconnect the power steering lines from the pump.





17. Remove two bolts (2) and the heater core supply tube (1).





18. Disconnect the ignition coil capacitor electrical connector.
19. Disengage the wire harness retainer (3) from the intake manifold support bracket.
20. Remove the studbolt (2) and remove the upper intake manifold support bracket.
21. Remove the spark plugs . Spark Plug - Removal
22. Remove the cylinder head covers, lower and upper oil pans, crankshaft vibration damper and engine timing cover Engine Timing Cover(s) - 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.

23. Rotate the crankshaft CW 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).

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.

24. 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.

25. Reset the RH 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.

26. Install the RH Camshaft Phaser Lock (5).
27. Loosen both the intake oil control valve (2) and exhaust oil control valve (7).
28. Remove the RH Camshaft Phaser Lock (5).
29. Remove the oil control valve (2) from the right side intake cam phaser and pull the phaser off of the camshaft.
30. Remove the oil control valve (7) from the right side exhaust cam phaser and pull the phaser off of the camshaft.





31. Remove the RH cam chain tensioner arm (6).
32. Remove two T30 bolts (4) and the RH cam chain tensioner (3).
33. Remove three T30 bolts (2) and the RH cam chain guide (1).





34. 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.

35. 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.

36. If required, remove the hydraulic lifters Hydraulic Lifter - Removal
37. 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.

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.

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

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.





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