Removal and installation of exhaust system components
Attention.
- A hot engine and exhaust system components can cause various burns. Turn off the engine and wait until it cools before removing exhaust system components.
- Remove/install the exhaust gas temperature sensor only if it is necessary to check or replace it, for example, if the codes for a faulty sensor appear. Each removal of the exhaust gas temperature sensor may result in a loss of tightness of the exhaust pipe, so after reinstalling the sensor, it is necessary to make sure that there are no exhaust gas leaks.
Note:
- If the DPF indicator on the instrument cluster illuminates, the DPF adjustment and manual regeneration procedure must be performed before removing exhaust system components.
- If the DPF indicator on the instrument panel starts to flash, check for faults in the DPF system.
- If the catalytic converter is replaced with a new one, the DPF initialization procedure must be performed.
1. Disconnect the negative battery terminal.
2. Remove the exhaust system components in the sequence shown in the figures.
Front-wheel drive (2WD) versions:
1. Main muffler.
2. Plate.
3. Bracket.
4. Tunnel crossbar.
5. Middle section of the exhaust pipe.
All-wheel drive (4WD) versions:
1. Main muffler.
2. Middle part of the exhaust pipe.
Note:replace the part with a new one after each removal.
1. Insulator.
2. Catalytic converter insulator.
3. Exhaust hose
4. Upper catalytic converter bracket.
5. Lower bracket of the catalytic converter.
6. Catalytic converter.
Note:replace the part with a new one after each removal.
Note: The rear exhaust insulator is mounted on rivets which must be drilled out to remove the insulator using a 5mm drill.
Note: When removing the catalytic converter, disconnect the connectors of exhaust gas temperature sensors No.1 and No.2, as well as the connector of the air-fuel ratio sensor.
3. To install the catalytic converter, do the following:
Fit the bolt and nuts shown in the figure.
Tighten the bolt and nuts in the sequence shown in the figure to a torque of 38-51 Nm.
Tighten bolts 1 and bolt 2 shown in the figure.
Tighten bolts 1 to 38-51 Nm.
Tighten bolt 2 to 38-51 Nm.
Tighten bolts 3 and bolt 4 shown in the figure.
Tighten bolts 3 and 4 to 38-51 Nm.
Tighten bolts 5 and 6, as shown in the figure.
Tighten bolts 5 and 6 to 38-51 Nm.
After installation, check again that the tightening torques of all fasteners are correct.
7. Further installation is carried out in the reverse order of removal.
