EXHAUST PIPE (for Long Wheelbase) INSTALLATION


  1. INSTALL EXHAUST PIPE ASSEMBLY TAIL


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

  2. INSTALL EXHAUST PIPE ASSEMBLY FRONT


    1. w/ Secondary air injection system:


      1. Install the 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. A01BCDO

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

        Minimum length
        40.5mm(1.594 in.)

        Tech Tips

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

    4. A01BD65E03

      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.

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

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

    7. 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 }
      Torque:
      Exhaust pipe assembly tail 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.

    8. For unleaded gasoline engine:


      1. Connect the sensor connector(s).

  3. CHECK EXHAUST GAS LEAKS
