EXHAUST PIPE INSTALLATION


  1. INSTALL FRONT EXHAUST PIPE ASSEMBLY


    1. A003GJI

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

      Minimum free length
      38.5 mm (1.52 in.)

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

      *1 Gasket
      *a Wooden Block

      Using a plastic-faced hammer and wooden block, tap in a new gasket until its surface is flush with the front exhaust pipe assembly.

      Note


      • Be sure to install the gasket so that it faces the correct direction.

      • Do not reuse the gasket.

      • Do not damage the gasket.

      • When connecting the front exhaust pipe assembly, do not push in the gasket with the front exhaust pipe assembly.

    3. Connect the front exhaust pipe assembly to the 2 exhaust pipe supports.

    4. Install a new gasket and the front exhaust pipe assembly and 2 compression springs with the 2 bolts.

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

  3. INSTALL CENTER EXHAUST PIPE ASSEMBLY


    1. Install a new gasket to the center exhaust pipe assembly.

    2. Connect the center exhaust pipe assembly to the 2 exhaust pipe supports.

    3. Install the center exhaust pipe assembly with the 2 bolts and 2 new nuts.

      Torque:
      48 N*m  { 489 kgf*cm, 35 ft.*lbf }

  4. INSTALL NITROGEN OXIDES SENSOR


    1. Temporarily install the nitrogen oxides sensor.

    2. Install the controller portion with the 2 nuts, and then attach the connector and clamp.

      Torque:
      8.0 N*m  { 82 kgf*cm, 71 in.*lbf }

      *a Torque Wrench Fulcrum Length

      Using SST, install the nitrogen oxides sensor.

      SST
      09224-00012
      Torque:
      Specified tightening torque
      55 N*m  { 561 kgf*cm, 41 ft.*lbf }

      Note


      • Replace with a new part if it is dropped or if it receives a strong impact.

      • Complete the installation so that there is no tension or slack in the harness of the nitrogen oxides sensor, and there is no interference.

      *a Torque Wrench Fulcrum Length

      Using a 14 mm union nut wrench, install the No. 4 exhaust gas temperature sensor to the front exhaust pipe assembly.

      Torque
      Specified tightening torque
      30 N*m {306 kgf*cm, 22 ft.*lbf}

      Note

      If the No. 4 exhaust gas temperature sensor is dropped, replace it with a new.

      Tech Tips


      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench Click here.

      • When using a union nut wrench (fulcrum length of 25 mm (0.984 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 26 N*m (268 kgf*cm, 19 ft.*lbf)

    2. Connect the connector to the No. 4 exhaust gas temperature sensor.

  6. INSTALL NO. 1 FRONT FLOOR HEAT INSULATOR


    1. Install the No. 1 front floor heat insulator with the 3 bolts.

      Torque:
      17 N*m  { 168 kgf*cm, 12 ft.*lbf }

  7. INSTALL EXHAUST PIPE DAMPER


    1. Install the exhaust pipe damper with the 2 bolts.

      Torque:
      19 N*m  { 194 kgf*cm, 14 ft.*lbf }

  8. INSTALL TAILPIPE ASSEMBLY


    1. Install a new gasket to the tailpipe assembly.

    2. Connect the tailpipe assembly to the exhaust pipe support.

    3. Connect the tailpipe assembly to the center exhaust pipe assembly.

    4. Install the 2 bolts.

      Torque:
      48 N*m  { 489 kgf*cm, 35 ft.*lbf }

  9. INSPECT FOR EXHAUST GAS LEAK


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