      Text in Illustration
      *1 Exhaust Manifold Converter Sub-assembly
      *2 Wooden Block
      *3 Gasket

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

      Standard 42.0 mm (1.65 in.)
      Minimum 40.5 mm (1.59 in.)

      Tech Tips

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

    2. Fully insert a new gasket to the exhaust manifold converter sub-assembly.

    3. A0004P1E25
      Text in Illustration
      *1 Exhaust Manifold Converter Sub-assembly
      *2 Front Exhaust Pipe Assembly
      *3 Gasket
      *a Space between flanges: 8.5 mm (0.335 in.)

      Using a plastic hammer and wooden block, tap in the new gasket until its surface is flush with the exhaust manifold converter sub-assembly.

      Note


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

      • Do not reuse the gasket.

      • Do not damage the gasket.

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

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

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

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

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

      Tech Tips

      After the installation, check that the gaps between the flanges of the exhaust manifold converter sub-assembly and front exhaust pipe assembly are consistent front-to-rear and left-to-right.
