PROCEDURE

1. INSTALL NO. 2 EXHAUST MANIFOLD HEAT INSULATOR

Torque:

10 N·m {102 kgf·cm, 7 ft·lbf}

2. INSTALL EXHAUST MANIFOLD (TWC: Front Catalyst)

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

(2) 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.

(3) 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

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

(2) 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

Torque:

10 N·m {102 kgf·cm, 7 ft·lbf}

7. INSTALL FRONT EXHAUST PIPE ASSEMBLY (TWC: Rear Catalyst)

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

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

(2) temporarily install 2 new gaskets to the exhaust manifold (TWC: Front Catalyst) and front exhaust pipe assembly (TWC: Rear Catalyst).

(3) Using a plastic hammer and wooden block, tap in each gasket until its surface is flush with the exhaust manifold (TWC: Front Catalyst) and front exhaust pipe assembly (TWC: Rear Catalyst).

NOTICE:

• Be sure to install the gasket in the correct direction.
• Do not reuse the gaskets.
• Do not damage the gaskets.
• Do not push in the gaskets by using the exhaust pipes when connecting them.

(1) Connect the front exhaust pipe assembly to the 3 exhaust pipe supports.

(2) Install the front exhaust pipe assembly (TWC: Rear Catalyst) to the exhaust manifold (TWC: Front Catalyst) with the 2 compression springs and 2 bolts.

Torque:

43 N·m {438 kgf·cm, 32 ft·lbf}

(3) After installation, check that the space between the flanges of the exhaust manifold (TWC: Front Catalyst) and front exhaust pipe assembly (TWC: Rear Catalyst) is consistent front-to-rear and left-to-right.

(4) Install the front exhaust pipe assembly (TWC: Rear Catalyst) to the tail exhaust pipe assembly with the 2 compression springs and 2 bolts.

Torque:

43 N·m {438 kgf·cm, 32 ft·lbf}

(5) After installation, check that the space between the flanges of the front exhaust pipe assembly (TWC: Rear Catalyst) and tail exhaust pipe assembly is consistent front-to-rear and left-to-right.

(6) Engage the wire harness clamp.

(7) Connect the heated oxygen sensor connector.

8. INSTALL FRONT FLOOR CENTER BRACE

Torque:

15 N·m {153 kgf·cm, 11 ft·lbf}
