Special Tool(s)

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, can cause engine failure.

All vehicles





1. Remove the bolts and the flexplate.





2. Using the special tools, remove and discard the crankshaft rear oil seal.
3. Mount the engine on a suitable stand.





4. Detach the engine control sensor wiring connectors from the upper intake manifold.





5. Detach the wiring retainer, remove the nut and the heated oxygen sensor (HO2S) electrical connector bracket.





6. Disconnect the exhaust gas recirculation (EGR) vacuum regulator electrical connector and remove the nut. Detach the wiring harness retainer.





7. Disconnect the knock sensor (KS) electrical connector.





8. Remove the nuts and the engine control wire harness.





9. Disconnect the idle air control (IAC) valve and the throttle position (TP) sensor electrical connectors, and detach the wiring retainer.





10. Remove the positive crankcase ventilation (PCV) tribe.





11. Disconnect the vacuum tube fittings from the EGR valve, EGR vacuum regulator and the intake manifold.





12. Disconnect the throttle body coolant hose.





13. Remove the bolts and upper intake manifold.
^ Inspect and, if necessary, install new gaskets.





14. Disconnect the engine coolant temperature (ECT) sensor electrical connector.





15. Disconnect the RH coil-on-plug electrical connectors and detach the wiring retainer.





16. Disconnect the radio interference capacitor electrical connector and detach the wiring retainers.





17. Disconnect the LH coil-on-plug electrical connectors and detach the wiring retainers.





18. Disconnect the camshaft position sensor (CMP) and oil pressure sensor electrical connectors and detach the wiring retainers.





19. Disconnect the crankshaft position (CKP) sensor electrical connector and detach the wiring retainers.





20. Disconnect the fuel rail pressure and temperature sensor electrical connector and vacuum tube.
^ Remove the engine vacuum harness.





21. Disconnect the fuel injector electrical connectors and remove the fuel charging wiring harness.





22. Remove the bolts and the lower intake manifold.
^ Inspect and, if necessary, install new gaskets.





23. CAUTION: When removing the coil-on-plugs, a slight twisting motion will break the seal and ease removal.

NOTE: LH shown, RH similar.

Remove the bolts and the 6 coil-on-plugs.





24. Remove the nut and the radio interference capacitor.





25. Remove the bolts and the RH valve cover.
^ Inspect and, if necessary, install a new gasket.
