    Object Number: 177825 Size: MH
  1. Install the new exhaust manifold gasket (2) to the cylinder head.

    2. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  2. Install the exhaust manifold (3). Secure the exhaust manifold with the eight bolts and one nut.

    3. Tighten
    Tighten the exhaust manifold bolts and nut to 23 N·m (17 lb ft).

  3. Install the exhaust manifold heat shield (1) to the exhaust manifold. Secure the exhaust manifold heat shield with the three bolts.

    4. Tighten
    Tighten the heat shield bolts to 15 N·m (11 lb ft).

  4. Install the exhaust manifold stiffener bracket. Secure the bracket with the two bolts.
