EXHAUST MANIFOLD INSTALLATION

PROCEDURE


  1. INSTALL NO. 2 EXHAUST MANIFOLD HEAT INSULATOR


    1. Install the No. 2 exhaust manifold heat insulator with the 3 bolts.

      Torque:
      12 N*m  { 122 kgf*cm, 9 ft.*lbf }

  2. INSTALL EXHAUST MANIFOLD


    1. Install a new exhaust manifold to head gasket to the cylinder head sub-assembly.

    2. Temporarily install the exhaust manifold with the 5 new nuts.

    3. Temporarily install the manifold stay with the 3 bolts.

    4. Tighten the 5 nuts.

      Torque:
      26 N*m  { 265 kgf*cm, 19 ft.*lbf }
    5. B008J8JN01

      Tighten the 3 bolts in the order shown in the illustration.

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

  3. INSTALL FRONT EXHAUST PIPE ASSEMBLY


    1. B008J8V

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

      Minimum length
      41.5 mm (1.63 in.)

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

    2. Using a wire brush, remove any foreign matter from the gasket installation surface.

    3. B008I9LC36
      *1 Exhaust Manifold
      *2 Gasket
      *a Wooden Block

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

      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.

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

    5. B008H78C02
      *1 Exhaust Manifold
      *2 Front Exhaust Pipe Assembly
      *3 Gasket
      *a Space between flanges: 8.5 mm (0.335 in.)

      Install the front exhaust pipe assembly with the 2 compression springs and 4 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 and front exhaust pipe assembly is consistent front-to-rear and left-to-right.

  4. INSTALL NO. 1 EXHAUST MANIFOLD HEAT INSULATOR


    1. Install the No. 1 exhaust manifold heat insulator with the 3 bolts.

      Torque:
      12 N*m  { 122 kgf*cm, 9 ft.*lbf }

  5. INSTALL WIRE HARNESS CLAMP BRACKET


    1. Install the wire harness clamp bracket with the bolt.

      Torque:
      39 N*m  { 398 kgf*cm, 29 ft.*lbf }

    2. Connect the clamp and connect the fuel tube sub-assembly to the wire harness clamp bracket.

    3. Connect the wire harness clamp to the wire harness clamp bracket.
