Engine











Disassembly (Steps 1-27)

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

CAUTION: 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, may cause engine failure.

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

1. Remove the bolts and the flexplate.





2. Using the special tools, remove and discard the crankshaft rear oil slinger.





3. Using the special tools, remove and discard the crankshaft rear seal.





4. Remove the 8 bolts and the crankshaft rear seal retainer plate.





5. Mount the engine on a suitable work stand.
6. Remove the special tool.





7. Remove the 3 bolts and the RH engine support insulator bracket.





8. NOTE: LH shown, RH similar.

Remove the cylinder block drain plugs and drain the coolant into a suitable container.





9. NOTE: LH shown, RH similar.

Install the cylinder block drain plugs.
^ Tighten to 24 Nm (18 lb-ft).





10. Disconnect the 2 coolant hoses from the oil filter adapter.





11. NOTE: RH shown, LH similar.

Disconnect the RH and LH camshaft position (CMP) sensor electrical connectors.





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





13. NOTE: RH shown, LH similar.

Disconnect the RH and LH variable camshaft timing (VCT) solenoid electrical connector.





14. Disconnect the 2 engine wiring harness retainers from the RH valve cover studs.





15. Disconnect the electrical connector retainer from the coolant tube.





16. Disconnect the cylinder head temperature (CHT) sensor electrical connector.





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





18. Remove the nut and the LH radio ignition interference capacitor.





19. NOTE: LH shown, RH similar.

Remove the 8 bolts and the 8 ignition coils.
^ Remove the ignition coil using a twisting motion while pulling up on the ignition coil.





20. Remove the engine wiring harness from the engine assembly.
21. Remove the 2 bolts and the 2 knock sensors (KS).





22. Remove the stud bolt and the coolant tube.
^ Discard the O-ring seal.





23. Remove the bolt and the RH CMP sensor.





24. Remove the bolt and the LH CMP sensor.





25. Remove the bolt and the crankshaft position (CKP) sensor.





26. CAUTION: 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.

CAUTION: When removing the valve cover, make sure to avoid damaging the variable camshaft timing (VCT) solenoid.

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

NOTE: LH shown, RH similar.

Loosen the fasteners 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.





27. Remove the bolts and the LH engine support insulator-to-cylinder block bracket.
