Refer to PROCEDURE - Step 2

Refer to PROCEDURE - Step 1

1. Install a new gasket to the front exhaust pipe assembly.
2. 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) 

3. 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) 

4. Engage the 2 clamps to connect the heated oxygen sensor (for bank 2) wire to the wire harness clamp bracket.
5. Connect the heated oxygen sensor (for bank 2) connector.

1. 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.

2. 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.
