INSTALLATION

PROCEDURE

1. INSTALL NO. 2 EXHAUST MANIFOLD HEAT INSULATOR

(a) Install the No. 2 exhaust manifold heat insulator to the exhaust manifold (TWC: Front Catalyst) with the 6 bolts.

Torque:

11 N·m {112 kgf·cm, 8 ft·lbf}

2. INSTALL EXHAUST MANIFOLD (TWC: Front Catalyst)

(a) Install a new exhaust manifold to head gasket to the cylinder head sub-assembly.

(b) Temporarily install the exhaust manifold (TWC: Front Catalyst), No. 1 upper front floor heat insulator and No. 1 exhaust manifold heat insulator.

HINT:

At this time, do not install the parts with bolts or nuts.

(c) Using a 12 mm deep socket wrench, temporarily install the exhaust manifold (TWC: Front Catalyst) to the cylinder head sub-assembly with 7 new nuts.

(d) Using the 12 mm deep socket wrench, tighten the 7 nuts in the order shown in the illustration.

Torque:

26 N·m {265 kgf·cm, 19 ft·lbf}

3. INSTALL MANIFOLD STAY

(a) Temporarily install the manifold stay to the exhaust manifold (TWC: Front Catalyst) and cylinder block sub-assembly with the bolt and nut.

(b) Tighten the bolt and nut in the order shown in the illustration.

Torque:

43 N·m {438 kgf·cm, 32 ft·lbf}

4. INSTALL NO. 1 EXHAUST MANIFOLD HEAT INSULATOR

(a) Using a 10 mm union nut wrench, install the No. 1 exhaust manifold heat insulator to the exhaust manifold (TWC: Front Catalyst) with the 5 bolts. Torque: Specified tightening torque : 10 N·m {102 kgf·cm, 7 ft·lbf} HINT: Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

*a Torque Wrench Fulcrum Length

5. INSTALL NO. 1 UPPER FRONT FLOOR HEAT INSULATOR

(a) Using a 10 mm union nut wrench, install the No. 1 upper front floor heat insulator to the vehicle body with the 2 nuts. Torque: Specified tightening torque : 4.9 N·m {50 kgf·cm, 43 in·lbf} HINT: Calculate the torque wrench reading when changing the fulcrum length of the torque wrench. Click here When using a 10 mm union nut wrench (fulcrum length of 22 mm (0.866 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)): 4.3 N*m (44 kgf*cm, 38 in.*lbf)
