Valve, Exhaust Gas RECIRCULATION: 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.
- Disconnect and isolate negative battery cable at battery.
- Remove EGR tube bolts (3) at exhaust gas recirculate (EGR) valve (2).
- Remove EGR tube (4) from EGR valve (2).
- Remove and discard gasket (5) located between EGR valve (2) and EGR tube (4).
- Disconnect electrical connector at EGR valve (2).
- Remove EGR valve mounting bolts (6).
- Remove EGR valve (2) from cylinder head (1).
- Remove and discard gasket located between EGR valve (2) and cylinder head (1).
