Part 1
ENGINE DISASSEMBLY - 3.0L
Disassembly
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:For additional information, see the engine exploded views in - Engine Assembly.
All vehicles
1. Remove the bolts and the flexplate.
2. Remove the engine-to-transaxle separator plate.
3. Using the Slide Hammer and the Crankshaft Rear Oil Seal Remover, remove and discard the crankshaft rear oil seal.
4. Mount the engine on a suitable stand.
5. Disconnect the engine block Knock Sensor (KS) electrical connector and detach the wire harness retainer, disconnect the Cylinder Head Temperature (CHT) sensor electrical connector and the cylinder head KS electrical connector.
6. Disconnect the electronic throttle control electrical connector.
7. Disconnect the Evaporative Emission (EVAP) canister purge valve electrical connector.
8. Disconnect the EGR regulator electrical connector and detach the wiring retainer.
9. Detach the wiring harness retainer from the upper intake manifold.
10. Disconnect the Manifold Absolute Pressure (MAP) electrical connector and detach the wiring retainer.
11. Disconnect the RH coil-on-plug electrical connectors.
- Detach the 2 wiring harness retainers.
Front Wheel Drive (FWD) vehicles
1. Disconnect the RH heated oxygen sensor (HO2S) electrical connector.
All vehicles
1. Disconnect the RH Variable Camshaft Timing (VCT) electrical connector.
2. Disconnect the Crankshaft Position (CKP) sensor electrical connector and detach the 2 wiring harness retainers.
3. Disconnect the 2 Camshaft Position (CMP) sensor electrical connectors and detach the wiring harness retainer from the engine front cover stud bolt.
4. Disconnect the fuel injector wiring harness electrical connector.
5. Disconnect the LH VCT electrical connector.
6. Disconnect the Engine Oil Pressure (EOP) switch electrical connector and detach the wiring retainer.
7. Disconnect the LH HO2S electrical connector.
8. Disconnect the 3 LH coil-on-plug electrical connectors.
- Detach the 2 wiring harness retainers.
9. Remove the nut and the B+ wire from the generator.
10. Detach the 2 wiring harness retainers.
- Remove the B+ harness from the engine.
11. Remove the EGR tube fitting from the EGR valve.
12. Remove the 2 upper intake manifold bracket bolts (1 shown).
CAUTION: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 is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.
13. Remove the 7 bolts and the upper intake manifold.
- Remove and discard the gaskets.
14. Remove the 4 bolts and the fuel rail and injectors as an assembly.
CAUTION: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 is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.
15. Remove the 8 lower intake manifold bolts and the lower intake manifold.
- Remove and discard the gaskets.
NOTE:When removing the coil-on-plugs, a slight twisting motion will break the seal and ease removal.
NOTE:LH shown, RH similar.
16. Remove the 6 bolts and the 6 coil-on-plugs.
