Part 1
Engine
NOTICE: Remove the cylinder heads before removing the crankshaft. Failure to do so may 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, may cause engine failure.
NOTE: The flexplate and crankshaft rear seal must be removed before mounting the engine on the engine stand.
NOTE: For additional information, refer to the exploded view under the Assembly procedure.
1. Remove the 8 bolts and the flexplate.
- Discard the 8 flexplate bolts.
2. Remove the spacer plate.
3. NOTE: Inspect the ignition pulse ring for damage. If the ignition pulse ring has been dropped or has any visual damage, it must be discarded.
Remove the crankshaft ignition pulse ring.
4. Disconnect the electrical connector and remove the bolt and the Crankshaft Position (CKP) sensor.
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. Remove the Engine Lifting Bracket and Engine Support Brackets.
8. Disconnect the Engine Oil Pressure (EOP) switch electrical connector and wiring harness retainers.
9. Disconnect the LH Variable Camshaft Timing (VCT) variable force solenoid electrical connector and the 2 wiring harness retainers.
10. Disconnect the 3 engine wiring harness position retainers from the LH valve cover.
11. Disconnect the wiring harness retainer, the Knock Sensor (KS) and Cylinder Head Temperature (CHT) sensor electrical connectors.
12. Disconnect the LH and RH Camshaft Position (CMP) electrical connectors.
13. Remove the nut and the wiring harness ground cable.
14. Remove the nut and the radio interference capacitor.
15. Disconnect the RH VCT (Variable Camshaft Timing) variable force solenoid electrical connector and the 2 wiring harness retainers.
16. Disconnect the 3 engine wiring harness position retainers from the RH valve cover and remove the engine wiring harness.
17. NOTE: RH shown, LH similar.
Disconnect the 8 ignition wires from the valve cover retainers and the lower spark plugs.
18. Remove the 2 bolts and the LH and RH CMP (Camshaft Position) sensors.
19. Remove the 2 bolts and the RH and LH KS (Knock Sensor).
20. Remove the 2 bolts and the LH exhaust manifold heat shield.
21. Remove the 8 nuts, the 8 studs, the LH exhaust manifold and the 2 gaskets.
- Discard the gaskets, nuts and studs.
- Inspect the exhaust manifold.
22. Remove the 2 bolts and the RH exhaust manifold heat shield.
23. Remove the 8 nuts, the 8 bolts, the RH exhaust manifold and the 2 gaskets.
- Discard the gaskets, nuts and studs.
- Inspect the exhaust manifold.
24. Remove the 3 bolts and the LH engine support insulator-to-cylinder block bracket.
25. Remove the 3 bolts and the RH engine support insulator.
26. Remove the bolt and the oil level indicator tube.
- Discard the O-ring seal.
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.
NOTICE: Remove the valve cover carefully, or the Variable Camshaft Timing (VCT) variable force solenoid may be damaged.
NOTE: The bolts are part of the valve cover and should not be removed.
Loosen the 10 bolts and remove the LH valve cover.
- 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.
28. 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.
NOTICE: Remove the valve cover carefully, or the Variable Camshaft Timing (VCT) variable force solenoid may be damaged.
NOTE: The bolts are part of the valve cover and should not be removed.
Loosen the 10 bolts and remove the RH valve cover.
- 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.
29. Remove the 4 bolts and the oil filter adapter.
30. Remove the bolt and the heater coolant tube.
