Part 1

Engine













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

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.

NOTE: The flexplate or flywheel, crankshaft rear seal and the crankshaft rear oil slinger must be removed before mounting the engine on the engine stand.

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

Vehicles with automatic transmission

1. Remove the 6 bolts and the flexplate.





Vehicles with manual transmission

2. Remove the 6 flywheel bolts.

3. NOTICE: The flywheel is a press fit on the crankshaft pilot. Do not use screwdrivers or prybars to remove the flywheel or damage to the flywheel or engine may occur.

Remove the flywheel.

- Install 2 of the removed flywheel bolts in the 2 holes shown on the flywheel flange.
- Tighten the 2 bolts evenly to push the flywheel off the crankshaft pilot.





All vehicles

4. Using the Slide Hammer and the Crankshaft Rear Oil Slinger Remover, remove the crankshaft rear oil slinger.
- Discard the crankshaft rear oil slinger.





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





6. Remove the 8 bolts and the crankshaft rear seal retainer plate.
- 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.

Clean and inspect the sealing surfaces.





7. Mount the engine on a suitable work stand.

8. Remove the Engine Lifting Bracket.





9. Disconnect the RH Camshaft Position (CMP) sensor electrical connector.





10. NOTE: RH shown, LH similar.

Disconnect the RH and LH Variable Camshaft Timing (VCT) solenoid electrical connectors.





11. Detach the engine wiring harness pin-type retainers.





12. Remove the nut and the RH radio ignition interference capacitor.





13. NOTE: When reusing liquid or vapor tube connectors, make sure to use compressed air to remove any foreign material from the connector retaining clip area before separating from the tube.

NOTE: LH shown, RH similar.

Remove the PCV tubes from the LH and RH valve covers.

- Disconnect the quick connect fittings.
- Push the connector toward the valve cover to release pressure.
- Push the release tab clockwise.
- Disconnect the quick connect fitting.





14. NOTE: RH shown, LH similar.

Disconnect the 4 RH and 4 LH ignition coil electrical connectors.





15. Disconnect the 3 engine wiring harness retainers from the RH valve cover studs.





16. Disconnect the 2 engine wiring harness retainers from the LH valve cover studs.





17. Detach the engine wiring harness pin-type retainers.





18. Disconnect the Cylinder Head Temperature (CHT) sensor electrical connector.





19. Detach the CHT sensor jumper harness electrical connector pin-type retainer.





20. Disconnect the Knock Sensor (KS) electrical connector and pin-type retainer.





21. Disconnect the LH Heated Oxygen Sensor (HO2S) electrical connector.
- Detach the engine wiring harness retainer from the stud bolt.





22. Disconnect the Engine Oil Pressure (EOP) switch electrical connector.





23. Remove the engine wiring harness from the engine.

24. Remove the nut and ground strap from the stud bolt.





25. NOTE: LH shown, RH similar.

Remove the 8 bolts and the 8 ignition coils.





26. Remove the bolt and the oil level indicator tube.





27. 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.

NOTE: When removing the valve cover, make sure to avoid damaging the VCT solenoid.

NOTE: The bolts are part of the valve cover and should not be removed.

NOTE: LH shown, RH similar.

Loosen the 19 bolts and remove the valve covers.
- Clean the valve cover mating surface of the cylinder head with silicone gasket remover and metal surface prep. Follow the directions on the packaging.
- Inspect the valve cover gasket. If the gasket is damaged, remove and discard the gasket. Clean the valve cover gasket groove with soap and water or a suitable solvent.
