Part 2

Engine













NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

NOTICE: Early build engines have 11 fastener valve covers, late build engines have 9 fastener valve covers. Do not attempt to install bolts in the 2 empty late build valve cover holes or damage to the valve cover will occur.

NOTE: On early build engines, the timing chain rides on the inner side of the RH timing chain guide. Late build engines are equipped with a different design RH timing chain guide that requires the timing chain to ride on the outer side of the RH timing chain guide. For service, all replacement RH timing chain guides will be the late build design.

NOTE: For additional information, refer to the exploded view under the Assembly procedure.

FWD vehicles

48. Remove the 4 nuts and the RH catalytic converter.
- Discard the nuts and the gasket.





All vehicles

49. Remove the 3 bolts and the RH exhaust manifold heat shield.





50. Remove the 6 nuts and the RH exhaust manifold.
- Discard the nuts and exhaust manifold gaskets.





51. Clean and inspect the RH exhaust manifold. For additional information, refer to Engine.

52. Remove and discard the 6 RH exhaust manifold studs.





53. Remove the RH cylinder block drain plug or, if equipped, the block heater.
- Allow coolant to drain from the cylinder block.





54. Remove the LH cylinder block drain plug.
- Allow coolant to drain from the cylinder block.





55. Remove the pin-type retainer and the cover.





56. Remove the 2 bolts and the engine lifting eye.





57. Remove the bolt and the upper intake manifold bracket.

All-Wheel Drive (AWD) vehicles

59. Remove the 2 bolts and the catalytic converter bracket.





All vehicles

60. Remove the 4 bolts and the fuel rail and injectors as an assembly.





61. Remove the 3 thermostat housing-to-lower intake manifold bolts.
- Remove the thermostat housing and discard the gasket.





62. NOTICE: If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris if found, install a new intake manifold. Failure to follow these instructions can result in engine damage.

Remove the 10 bolts and the lower intake manifold.

- Discard the gaskets.





63. Disconnect and remove the CHT sensor jumper harness.





64. Remove the bolt and the LH CMP sensor.
