ON-VEHICLE SERVICE

Exhaust Manifold Assembly

Removal

1. Turn off all the electrical equipment and ignition switch.
2. Disconnect the negative battery cable.
3. Remove the engine trim cover assembly (

See page 10-10

).

4. Remove the exhaust manifold heat insulator.

a. Remove 4 fixing bolts (arrow) from the exhaust

manifold heat insulator.



(Tightening torque: 23 ± 2 N·m)

b. Remove the exhaust manifold heat insulator.

5. Remove the exhaust manifold assembly.

a. Remove 4 coupling nuts (arrow), disconnect the

connection between exhaust manifold assembly and
precatalytic converter assembly, and take off the
gasket in the connecting part.



(Tightening torque: 50 ± 5 N·m)

WARNING

 The temperature of exhaust system is very high when engine is running. Before removal, make sure that

engine has stopped running, otherwise, there is a risk of scald injury.

CAUTION

 Be sure to wear necessary safety equipment to prevent accidents when repairing.
 Try to prevent body paint surface from being scratched during removal and installation.

b. Remove 8 fixing nuts (arrow) from the exhaust

manifold assembly.

(Tightening torque: 23 ± 2 N·m)

c. Remove the exhaust manifold assembly, and remove the gasket from the exhaust manifold assembly.

Inspection

1. Measure warpage on the surface of exhaust manifold

assembly with a precision ruler and a feeler gauge. If
warpage on the surface is greater than 0.5 mm, replace
it.

2. Measure warpage on the surface of cylinder head

exhaust side with a precision ruler and a feeler gauge. If
warpage on the surface is greater than 0.04 mm, replace
it.

3. Check that there are no scratches and roughness on

exhaust manifold gasket. Otherwise, replace it.

Precatalytic Converter Assembly

Removal

1. Turn off all the electrical equipment and ignition switch.
2. Disconnect the negative battery cable.
3. Remove the engine trim cover assembly (

See page 10-10

).

4. Remove the precatalytic converter assembly.

a. Take off and disconnect the upstream oxygen sensor

connector (arrow) from the bracket.

b. Remove 4 fixing bolts (arrow) from the exhaust

manifold heat insulator, and remove the exhaust
manifold heat insulator.
