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


    1. B008MAU

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

      Standard Length 43.0 mm (1.69 in.)
      Minimum Free Length 41.5 mm (1.63 in.)

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

    2. Temporarily install a new exhaust pipe gasket to the exhaust manifold converter sub-assembly (TWC: Front Catalyst).

    3. B008L50C68
      *1 Exhaust Manifold Converter Sub-assembly (TWC: Front Catalyst)
      *2 Exhaust Pipe Gasket
      *a Wooden Block

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

      Note


      • Be sure to install the exhaust pipe gasket in the correct direction.

      • Do not reuse the exhaust pipe gasket.

      • Do not damage the exhaust pipe gasket.

      • Do not push in the exhaust pipe gasket by using the exhaust pipes when connecting them.

    4. Connect the front exhaust pipe assembly (TWC: Rear Catalyst) to the 2 exhaust pipe supports.

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

      Torque:
      43 N*m  { 438 kgf*cm, 32 ft.*lbf }

      Tech Tips

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

      *1 Exhaust Manifold Converter Sub-assembly (TWC: Front Catalyst)
      *2 Front Exhaust Pipe Assembly (TWC: Rear Catalyst)
      *3 Exhaust Pipe Gasket
      *a Space between Flanges: 8.5 mm (0.335 in.)

    6. for Rear Heated Oxygen Sensor:


      1. Engage the clamp and connect the heated oxygen sensor connector.

    7. for Rear Air Fuel Ratio Sensor:


      1. Engage the clamp and connect the air fuel ratio sensor connector.

  4. INSTALL FRONT FLOOR CENTER BRACE


    1. Install the 3 front floor center braces to the vehicle body with the 12 bolts.

      Torque:
      29 N*m  { 296 kgf*cm, 21 ft.*lbf }

  5. INSTALL TAIL EXHAUST PIPE ASSEMBLY


    1. B008MAU

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

      Standard Length 40 mm (1.57 in.)
      Minimum Free Length 38.5 mm (1.52 in.)

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

    2. Temporarily install a new exhaust pipe gasket to the front exhaust pipe assembly (TWC: Rear Catalyst).

    3. B008L50C68
      *1 Front Exhaust Pipe Assembly (TWC: Rear Catalyst)
      *2 Exhaust Pipe Gasket
      *a Wooden Block

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

      Note


      • Be sure to install the gasket in the correct direction.

      • Do not reuse the exhaust pipe gasket.

      • Do not damage the exhaust pipe gasket.

      • Do not push in the exhaust pipe gasket by using the exhaust pipes when connecting them.

    4. Connect the tail exhaust pipe assembly to the 4 exhaust pipe supports.

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

      Torque:
      43 N*m  { 438 kgf*cm, 32 ft.*lbf }

      Tech Tips

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

      B008LHBC18
      *1 Front Exhaust Pipe Assembly (TWC: Rear Catalyst)
      *2 Tail Exhaust Pipe Assembly
      *3 Exhaust Pipe Gasket
      *a Space between Flanges: 6.5 mm (0.256 in.)

  6. INSPECT FOR EXHAUST GAS LEAK

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


    1. Perform Inspection After Repair after repairing an exhaust gas leak.

  7. INSTALL FRONT FLOOR COVER LH (w/ Cover)


    1. Engage the 5 clamps to install the front floor cover LH to the vehicle body with the 2 bolts and clip.

      Torque:
      7.5 N*m  { 76 kgf*cm, 66 in.*lbf }

  8. INSTALL FRONT FLOOR COVER RH (w/ Cover)

    Tech Tips

    Perform the same procedure as for the front floor cover LH.
