3. INSTALL FRONT EXHAUST PIPE ASSEMBLY

(a) Install a new gasket to the front exhaust pipe assembly.

(b) Install the front exhaust pipe assembly to the exhaust manifold sub-assembly LH (TWC: front catalyst) with 2 new nuts.

Torque:

43 N·m {438 kgf·cm, 32 ft·lbf}

(c) Connect the exhaust pipe clamp to the No. 1 exhaust pipe support bracket and tighten the bolt.

Torque:

21 N·m {214 kgf·cm, 15 ft·lbf}

(d) Engage the 2 clamps to connect the heated oxygen sensor (for bank 2) wire to the wire harness clamp bracket.

(e) Connect the heated oxygen sensor (for bank 2) connector.

4. INSTALL CENTER EXHAUST PIPE ASSEMBLY

(a) Inspect the free length.

(1) Using a vernier caliper, measure the free length of the compression spring. Free Length of Compression Spring: Standard Length Minimum Length 42 mm (1.65 in.) 40.5 mm (1.59 in.) If the length is not as specified, replace the compression spring.

(b) Using a plastic hammer and a wooden block, tap in a new gasket until its surface is flush with the front No. 3 exhaust pipe sub-assembly. NOTICE: Install the gasket in the correct direction. Do not reuse the gasket. Do not damage the gasket by dropping it, etc. Do not damage the outer surface of the gasket. Do not push in the gasket with the center exhaust pipe sub-assembly (TWC: rear catalyst) when connecting it.

(c) Install the center exhaust pipe sub-assembly (TWC: rear catalyst) to the front No. 3 exhaust pipe sub-assembly with the 2 compression springs and 2 bolts. Torque: 43 N·m {438 kgf·cm, 32 ft·lbf} NOTICE: After the installation, check that the gaps between the flanges of the center exhaust pipe sub-assembly (TWC: rear catalyst) and front No. 3 exhaust pipe sub-assembly are consistent front-to-rear and left-to-right.

*1 Center Exhaust Pipe Sub-assembly (TWC: Rear Catalyst) *2 Front No. 3 Exhaust Pipe Sub-assembly *3 Gasket *a Space between flanges: 8.5 mm (0.335 in.)

(d) Inspect the free length.

(1) Using a vernier caliper, measure the free length of the compression spring. Free Length of Compression Spring: Standard Length Minimum Length 42 mm (1.65 in.) 40.5 mm (1.59 in.) If the length is not as specified, replace the compression spring.

(e) Using a plastic hammer and a wooden block, tap in a new gasket until its surface is flush with the center No. 2 exhaust pipe sub-assembly. NOTICE: Install the gasket in the correct direction. Do not reuse the gasket. Do not damage the gasket by dropping it, etc. Do not damage the outer surface of the gasket. Do not push in the gasket with the center exhaust pipe sub-assembly (TWC: rear catalyst) when connecting it.

*1 Gasket *2 Center No. 2 Exhaust Pipe Sub-assembly *a Wooden Block *b Plastic Hammer

(f) Install the center exhaust pipe sub-assembly (TWC: rear catalyst) to the center No. 2 exhaust pipe sub-assembly with the 2 compression springs and 2 bolts. Torque: 43 N·m {438 kgf·cm, 32 ft·lbf} NOTICE: After the installation, check that the gaps between the flanges of the center exhaust pipe sub-assembly (TWC: rear catalyst) and center No. 2 exhaust pipe sub-assembly are consistent front-to-rear and left-to-right.

*1 Center Exhaust Pipe Sub-assembly (TWC: Rear Catalyst) *2 Center No. 2 Exhaust Pipe Sub-assembly *3 Gasket *a Space between flanges: 8.5 mm (0.335 in.)

(g) Install 2 new gaskets to the center exhaust pipe assembly and the front exhaust pipe assembly.

(h) Connect the 2 exhaust pipe supports to install the center exhaust pipe assembly to the vehicle.

(i) Install the center exhaust pipe assembly to the front exhaust pipe assembly and exhaust manifold sub-assembly RH (TWC: front catalyst) with 2 new bolts and 2 new nuts.

Torque:

43 N·m {438 kgf·cm, 32 ft·lbf}

(j) Engage the clamp to connect the heated oxygen sensor (for bank 1) wire to the vehicle.

(k) Pass the connector through the hole to the inside of the vehicle and install the grommet of the heated oxygen sensor (for bank 1) wire.

(l) Connect the heated oxygen sensor (for bank 1) connector.

5. INSTALL TAIL EXHAUST PIPE ASSEMBLY

(a) Install a new gasket to the center exhaust pipe assembly.

(b) Connect the 4 exhaust pipe supports to install the tail exhaust pipe assembly to the vehicle.

(c) Install the tail exhaust pipe assembly to the center exhaust pipe assembly with 2 new bolts.

Torque:

43 N·m {438 kgf·cm, 32 ft·lbf}

6. INSTALL INSTRUMENT PANEL FINISH PANEL END LH

(a) Engage the 3 guides and install the instrument panel finish panel end LH.

(b) Install the clip.

7. INSPECT FOR EXHAUST GAS LEAK

If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.

(a) Perform Inspection After Repair after repairing an exhaust gas leak.
