EXHAUST PIPE (for Super Long Wheelbase) INSTALLATION


  1. INSTALL EXHAUST PIPE ASSEMBLY TAIL

  2. INSTALL EXHAUST PIPE ASSEMBLY CENTER


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

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

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

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

  3. INSTALL EXHAUST PIPE ASSEMBLY FRONT


    1. w/ Secondary air infection system:


      1. Install the air fuel ratio sensor. Click here

        Torque:
        44 N*m  { 449 kgf*cm, 32 ft.*lbf }

    2. For Unleaded gasoline engine:


      1. Install the oxygen sensor. Click here

        Torque:
        44 N*m  { 449 kgf*cm, 32 ft.*lbf }

    3. Inspect the compression spring.


      1. A003DPX

        Using vernier calipers, measure the free length of the compression springs.

        Minimum length
        40.5 mm (1.594 in.)

        Tech Tips

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

    4. A003FTXE03

      Install the gasket.


      1. Fully insert a new gasket to the exhaust manifold by hand.

      2. Using a wooden block, uniformly strike the gasket so that the gasket and exhaust manifold are properly fit.

        Note


        • Be careful with the installation direction of the gasket.

        • Do not reuse the gasket.

        • Do not damage the gasket.

        • To ensure a proper seal, do not use the exhaust pipe assembly front to force the gasket onto the exhaust manifold.

      3. Install a new gasket to the exhaust pipe assembly front.

      4. Connect the exhaust pipe assembly front to the exhaust pipe support.

      5. Install the exhaust pipe assembly front with the 4 bolts, 2 nuts, and 2 compression springs.

        Torque:
        Exhaust manifold side
        43 N*m  { 438 kgf*cm, 32 ft.*lbf }
        Exhaust pipe assembly center side
        48 N*m  { 489 kgf*cm, 35 ft.*lbf }

        Note

        After installation, check that the clearance is almost the same at any point between the flanges of the exhaust manifold and exhaust pipe assembly front.

    5. For Unleaded gasoline engine:


      1. Connect the sensor connector(s).

  4. CHECK FOR EXHAUST GAS LEAKS
