12 N*m{122 kgf*cm, 9 ft.*lbf}

Install the No. 2 exhaust manifold heat insulator with the 2 bolts.

Torque:

12 N*m{122 kgf*cm, 9 ft.*lbf}

Install a new gasket.

Install the exhaust manifold converter sub-assembly with the 5 nuts in the order shown in the illustration.

Torque:

37 N*m{377 kgf*cm, 27 ft.*lbf}

Install the No. 2 manifold stay with the bolt and nut.

Torque:

44 N*m{449 kgf*cm, 33 ft.*lbf}

Install the manifold stay with the bolt and nut.

Torque:

44 N*m{449 kgf*cm, 33 ft.*lbf}

Using SST, install the air fuel ratio sensor.

SST

09224-00010

Torque:

without SST:

44 N*m{449 kgf*cm, 32 ft.*lbf}

with SST:

40 N*m{408 kgf*cm, 30 ft.*lbf}

NOTICE:

1. This torque value can be obtained by using a torque wrench with a fulcrum length of 300 mm (11.81 in.) and SST with a measure of 30 mm (1.18 in.) (COROLLA_ZRE142 RM000000UYX0ETX.html).
   
2. This torque value is effective when SST is parallel to the torque wrench.
   

Connect the air fuel ratio sensor connector and wire harness clamp.

Install the No. 1 exhaust manifold heat insulator with the 4 bolts.

Torque:

12 N*m{122 kgf*cm, 9 ft.*lbf}

Using a vernier caliper, measure the free length of the compression springs.

HINT:

If the free length is less than the minimum, replace the compression spring.

Remove the remains of exhaust manifold converter with wire brash.

Fully insert a new gasket to the exhaust manifold.

NOTICE:

1. Be sure to install the gasket in the correct direction.
   
2. Do not reuse the gasket.
   
3. Do not damage the gasket.
   

Install the front exhaust pipe assembly with the 2 bolts and 2 compression springs.

Torque:

43 N*m{440 kgf*cm, 32 ft.*lbf}

Connect the heated oxygen sensor connector.

Using a vernier caliper, measure the free length of the compression springs.

HINT:

If the free length is less than the minimum, replace the compression spring.

Fully insert a new gasket to the center exhaust pipe assembly.

NOTICE:

1. Be sure to install the gasket in the correct direction.
   
2. Do not reuse the gasket.
   
3. Do not damage the gasket.
   

Install a new gasket to the front exhaust pipe assembly.

Connect the center exhaust pipe assembly to the 2 exhaust pipe supports.

Install the center exhaust pipe assembly with the 4 bolts and 2 compression springs.

Torque:

43 N*m{440 kgf*cm, 32 ft.*lbf}

Using SST, slowly turn the V-ribbed belt tensioner clockwise and install the V-ribbed belt.

SST

09216-42010(09216-04010)

NOTICE:

1. Make sure that SST and other tools are set to the tensioner securely.
   
2. When compressing the V-ribbed belt tensioner, slowly turn the tensioner.
