Removal and installation of exhaust system components
Caution: 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.
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. Insulator.
3. Bracket.
4. Heated oxygen sensor.
5. Tunnel crossbar.
6. Three-way catalytic converter.
Note:replace the part with a new one after each removal.
All-wheel drive (4WD) versions:
1. Main muffler.
2. Heated oxygen sensor.
3. Three-way catalytic converter.
Note:
: replace the part with a new one after each removal.
: use a special tool or device.
1. Air-fuel ratio sensor.
2. Clamps.
3. Insulator.
4. Exhaust manifold insulator.
5. Exhaust manifold (with heated three-way catalytic converter).
6. Exhaust manifold gasket.
Note:
: replace the part with a new one after each removal.
: use a special tool or device.
Note: The rear exhaust insulator is mounted on rivets which must be drilled out to remove the insulator using a 5mm drill.
Note:
- The exhaust manifold must be removed together with the bracket installed underneath it.
- To remove the exhaust manifold, remove the front cross member.
3. To install the exhaust manifold, first tighten the nuts (1) and (2) shown in the figure by hand. Then tighten the nuts (1) and (2) to a torque of 33-53 Nm.
4. Hand tighten the exhaust manifold mounting nuts (3), (4) and (5) shown in the figure. Then tighten nuts (3), (4) and (5) to a torque of 43-64 Nm.

5. Tighten the exhaust manifold mounting nuts (1) and (2), shown in the figure above, to a torque of 43-64 Nm.
6. Tighten bolts (6) and (7) shown in the figure. Tighten bolt (6) first, then bolt (7) to a torque of 38-51 Nm.
7. Further installation is carried out in the reverse order of removal.
