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: Remove the cylinder heads before removing the crankshaft. Failure to do so can result in engine damage.

NOTE: If the components are to be reinstalled, they must be installed in their original location. Mark the components for installation into their original location.

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

1. Remove the engine. For additional information, refer to Engine - Manual Transmission Engine - Removal - Manual Transmission or Engine - Automatic Transmission Engine - Removal - Automatic Transmission.

2. NOTICE: Loosen the bolts evenly to prevent clutch pressure plate damage.

NOTE: If the parts are to be reused, index-mark the pressure plate to the flywheel.

Remove the 6 pressure plate bolts, remove the pressure plate and the clutch disc.

- Discard the pressure plate bolts.





3. NOTE: Flexplate shown, flywheel similar.

NOTE: The flexplate/flywheel bolts are torque-to-yield design and are not reusable.

Remove the 8 bolts and the flywheel or flexplate.

- Discard the bolts.

- Remove the engine separator plate.




4. NOTE: Inspect the crankshaft sensor ring for damage. If the crankshaft sensor ring has been dropped or has any visual damage, it must be discarded.

Remove the crankshaft sensor ring.





5. Using the Slide Hammer and the Crankshaft Rear Oil Seal Remover, remove and discard the crankshaft rear seal.





6. Mount the engine on a work stand.

7. Disconnect the oil level sensor electrical connector and the 2 wiring harness retainers.





8. Disconnect the Engine Oil Pressure (EOP) switch electrical connector and the 2 wiring harness retainers.





9. Disconnect the LH intake and exhaust Camshaft Position (CMP) sensor electrical connectors.
- Remove the 2 bolts and the LH intake and exhaust CMP sensors.





10. Disconnect the 2 Knock Sensor (KS) electrical connectors.





11. Disconnect the RH intake and exhaust Camshaft Position (CMP) sensor electrical connectors.
- Remove the 2 bolts and the RH intake and exhaust CMP sensors.





12. Disconnect the Cylinder Head Temperature (CHT) sensor and the Crankshaft Position (CKP) sensor electrical connectors.





13. NOTE: RH shown, LH similar.

Disconnect the 4 Variable Camshaft Timing (VCT) variable force solenoid electrical connectors.





14. NOTE: RH shown, LH similar.

Disconnect the 8 ignition coil electrical connectors.





15. NOTE: RH shown, LH similar.

Detach the 9 wiring harness retainers from the RH valve cover and the 10 wiring harness retainers from the LH valve cover.





16. Detach the 2 wiring harness retainers from the engine front cover and stud bolts.

- Remove the wiring harness from the engine.





17. NOTE: When removing the ignition coils, a slight twisting motion will break the seal and ease removal. RH shown, LH similar.

Remove the 8 bolts and the 8 ignition coils.





18. 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. Use a plastic scraping tool to remove all traces of old sealant.

Loosen the 14 bolts and remove the RH valve cover and gasket.

- Clean the valve cover mating surface of the cylinder head with silicone gasket remover and metal surface prep. Follow the directions on the packaging.

- Discard the valve cover gasket. Clean the valve cover gasket groove with soap and water or a suitable solvent.





19. Remove the oil level indicator.

20. 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. Use a plastic scraping tool to remove all traces of old sealant.

Loosen the 14 bolts and remove the LH valve cover and gasket.

- Clean the valve cover mating surface of the cylinder head with silicone gasket remover and metal surface prep. Follow the directions on the packaging.

- Discard the valve cover gasket. Clean the valve cover gasket groove with soap and water or a suitable solvent.





21. NOTE: RH shown, LH similar.

Inspect the 2 VCT variable force solenoid seals. Remove any damaged seals.

- Using the Differential Bearing Cone Installer and Handle, remove the seal(s).





22. NOTE: RH shown, LH similar.

Inspect the spark plug tube seals. Remove any damaged seals.

- Using the VCT Spark Plug Tube Seal Remover and Handle, remove the seal(s).





23. Remove the 8 nuts and the RH exhaust manifold.
- Discard the gasket.




24. Clean and inspect the RH exhaust manifold. For additional information, refer to Engine System - General Information Exhaust Manifold Cleaning and Inspection.

25. Remove and discard the 8 RH exhaust manifold studs.





26. Remove the 8 nuts and the LH exhaust manifold.
- Discard the gasket.





27. Clean and inspect the LH exhaust manifold. For additional information, refer to Engine System - General Information Exhaust Manifold Cleaning and Inspection.

28. Remove and discard the 8 LH exhaust manifold studs.





29. Remove the 4 bolts and the coolant pump pulley.





30. Remove the 4 bolts and the coolant pump.
- Remove and discard the O-ring seal.
