Begin the right Exhaust Manifold (3.4L) replacement task by disconnecting the air cleaner intake duct and accelerator cable bracket from the
Throttle Body. To obtain better access to the engine the system should be rotated so technicians can successfully remove four sequential parts including the manifold absolute pressure (MAP) sensor along with the exhaust gas recirculation (EGR) pipe and ignition module and
Ignition Coils attached to their bracket. Disconnect the
Spark Plug Wires from right side spark plugs then unplug the evaporative emissions (EVAP) solenoid bracket before the heated
Oxygen Sensor (HO2S) electrical connector. Crossover exhaust pipe nuts should come off from the right Exhaust Manifold after using a vehicle lift with support to remove the
Catalytic Converter. The procedure begins by removing Exhaust Manifold heat shield bolts then the heat shields before proceeding to Exhaust Manifold nuts and manifold removal with the Exhaust Manifold Gasket. The repairing process involves cleaning both right Exhaust Manifold mating surfaces while the tasks related to manifold replacement also involve removing the heated Oxygen Sensor (HO2S). The first step in installation requires installing the heated Oxygen Sensor (HO2S) when previously removed then placing the Exhaust Manifold Gasket followed by the Exhaust Manifold and securing it with nuts tightened to 16 nm (12 ft. Lbs.). The lower and upper Exhaust Manifold heat shields need to be installed first while tightening their bolts to 10 nm (89 inch lbs.). Next, install the Catalytic Converter. To proceed with installation workers must lower the vehicle and attach the exhaust crossover pipe nuts to the right Exhaust Manifold followed by the evap solenoid bracket. After reconnecting the heated Oxygen Sensor (HO2S) electrical connector the technician should install Spark Plug Wires to the right side spark plugs followed by the ignition module and ignition coils with their bracket. The installation process should end with fitting the egr pipe and
MAP Sensor followed by returning the engine to its original position and installing the right and left engine mount struts and the accelerator cable bracket to the Throttle Body before installing the air cleaner intake duct.
