EGR Valve - Removal

3.5L





WARNING: The normal operating temperature of the exhaust gas recirculate (EGR) valve and tube is very high. Therefore, never work around or attempt to service any engine component until it is completely cooled.

NOTE: It is very important to disconnect the battery due to the addresses (cells) within the engine controller that store learned values related to powertrain operation. A malfunctioning EGR system can cause bad values to be stored in these cells that can cause an erroneous fault to occur after the system is repaired. Disconnecting the battery for at least two minutes will remove all power from the controller and reset these cells to normal default values.

1. Use a diagnostic scan tool to record any DTC's (Diagnostic Trouble Codes).
2. Disconnect and isolate negative battery cable at battery.
3. Remove purge solenoid from bracket.




4. Relocate the purge solenoid.




5. Unlock and disconnect the electrical connector from EGR valve.
6. Remove the wiper module, Wiper Module - Removal.
7. Remove shock tower brace and relocate.
8. Remove the upper intake manifold, Intake Manifold - Removal.




9. EGR valve (2) and tube (1).




10. Remove tube bolts (1) to EGR valve (3).
11. Remove tube (1) from intake manifold.
12. When removing EGR upper tube assembly being careful not to drop the silicone rubber seals in the intake manifold. Clean gasket surfaces on the EGR valve. Note that any loose dirt can lodge between the pintle and the seat and cause valve leakage that will give a rough idle and depressed manifold vacuum.
13. Remove EGR valve mounting bolts (2).
14. Remove EGR valve from vehicle.
15. Clean mounting surface.
