To remove the EGR valve and pipe on the 2.0L four-cylinder models, raise the vehicle and secure it on jackstands, then remove the right lower splash shield. Loosen the tube nut fitting of the EGR pipe on the exhaust manifold and pull it off. If it is stuck, use some penetrant. In the engine bay, first take off the air intake duct, then unscrew the large nut at the upper end of the EGR pipe to disconnect it from the EGR valve. The old EGR Pipe should be replaced and check the threads inside the EGR valve for damage. In the first step, the bolts of EGR pipe bracket must be removed and the connection of differential pressure feedback EGR sensor must be carefully removed. The EGR pipe must be discarded. Unplug the vacuum line from the EGR valve and remove the two mounting bolts. Pull off the EGR valve and discard the old gasket. Remove any carbon deposit and clean the mounting surfaces. No loose particles must remain. The EGR valve mounting bolts are to be tightened and a new EGR pipe is to be used. This is the reverse of the removal. For 2.3L models, drain engine coolant, remove upper radiator hose and hose from EGR (Exhaust Gas Recirculation) valve, remove two bolts and valve, discard old gasket and clean the surface. For 2.5L variants, remove the duct from the air filter housing, disconnect the wiring harness and coolant hose from the EGR valve, then remove the two bolts and valve and discard the gasket. Drain the cooling system. For V6 models from 2008 and earlier, disconnect the vacuum line and EGR pipe from the EGR valve. Remove the bolts joining EGR valve to intake manifold and remove and discard the old gasket. Clean the surfaces that were previously bolted together and ensure that no other particles remained. After that, you can reverse the process of removal. For the installation or removal of the V6 models made from 2009 to 2012, first remove and discard the gasket. Disconnect the electrical harness and the EGR tube as well. Remove the two bolts holding on the EGR. After that, you will reverse the process for installation. The intake air tube has to be removed in step 2 but first it is necessary to drain the cooling system and disconnect the EGR connector or cooler hose. Remove the two bolts on EGR valve remove it and discard the gasket. Repeat removal above for 2013 and later 2.5L models. Coolant needs refilling after fitment. The differential pressure feedback EGR system sensor requires the battery cable, electrical connector and hoses to be disconnected. Visually check the sensor for evidence of damage before reversing the removal steps for installation. When the battery is reconnected, the Powertrain Control Module must relearn idle and fuel trim strategy. To extract the EGR vacuum regulator valve, ensure battery cable disconnection and locate the valve. Disconnect electrical connector and vacuum hoses and remove mounting nuts/bolts. Installation is the reversal of removal. Furthermore, ensure tight fastener fit. After reconnecting the battery, the Powertrain Control Module must relearn idle as well as fuel trim strategy.
