EXHAUST GAS TEMPERATURE SENSOR - INSTALLATION

1. INSTALL EXHAUST GAS TEMPERATURE SENSOR (LOWER)

Temporarily install the exhaust gas temperature sensor (lower) with the 2 nuts.

Tighten the 2 nuts.

Torque:
6.4 N*m{ 65 kgf*cm, 57 in.*lbf}

Using SST, tighten the nut of the exhaust gas temperature sensor (lower).

SST
09023-38401

Torque:
30 N*m{ 306 kgf*cm, 22 ft.*lbf}

HINT:

Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).

2. INSTALL EXHAUST GAS TEMPERATURE SENSOR (UPPER)

Temporarily install the exhaust gas temperature sensor (upper) with the 3 nuts.

Tighten the 3 nuts.

Torque:
6.4 N*m{ 65 kgf*cm, 57 in.*lbf}

Using SST, tighten the nut of the exhaust gas temperature sensor (upper).

SST
09023-38401

Torque:
30 N*m{ 306 kgf*cm, 22 ft.*lbf}

HINT:

Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).

3. INSTALL EXHAUST MANIFOLD CONVERTER SUB-ASSEMBLY

Temporarily install the No. 1 manifold stay.

Temporarily install a new turbine outlet elbow gasket and exhaust manifold converter with the 3 nuts.

Temporarily install the 2 bolts and nut.

Tighten the 3 nuts (Pushing the manifold converter against the No. 1 manifold stay).

Torque:
25 N*m{ 255 kgf*cm, 18 ft.*lbf}

Tighten the 2 bolts and nut.

Torque:
56 N*m{ 571 kgf*cm, 41 ft.*lbf}

Temporarily install the No. 2 exhaust manifold stay with the 2 bolts and nut.

Tighten the 2 bolts (Pushing the No. 2 exhaust manifold stay against the manual transmission).

Torque:
56 N*m{ 571 kgf*cm, 41 ft.*lbf}

Tighten the nut.

Torque:
56 N*m{ 571 kgf*cm, 41 ft.*lbf}

Using pliers, slide the clip to install the No. 1 and No. 2 vacuum transmitting hose assembly.

HINT:

Make sure that the paint marks on the No. 1 and No. 2 vacuum transmitting hose assemblies and No. 1 and No. 2 vacuum pipes are aligned.

4. INSTALL FRONT EXHAUST PIPE ASSEMBLY

Using vernier calipers, measure the free length of the compression springs.

Minimum length:
38.5 mm (1.516 in.)

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

Fully insert 2 new gaskets to the exhaust manifold converter and front exhaust pipe assembly by hand.

NOTICE:

Be careful with the installation direction of the gasket.

Do not reuse the gasket.

Do not damage the gasket.

To ensure a proper seal, do not use the tail exhaust pipe to force the gasket onto the front exhaust pipe.

HINT:

Using a plastic hammer, uniformly strike the gasket so that the gasket and front exhaust pipe are properly fit.

Install the front exhaust pipe assembly.

Install the 2 bolts and 2 compression springs.

Torque:
43 N*m{ 439 kgf*cm, 32 ft.*lbf}

NOTICE:

After installation, check that the clearance is almost the same at any point between the flanges of the tail exhaust pipe assembly and front exhaust pipe assembly.

Install the 2 bolts and 2 compression springs.

Torque:
43 N*m{ 439 kgf*cm, 32 ft.*lbf}

NOTICE:

After installation, check that the clearance is almost the same at any point between the flanges of the exhaust manifold converter and front exhaust pipe assembly.
