  1. Install the throttle body gasket.
  2. Install the throttle body onto the intake manifold.
  3. Notice: All components being assembled must be at room temperature. Assembling components that are at different temperatures can distort the components and cause component damage.

    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.

  4. Install the throttle body bolts.
  5. Tighten
    Tighten the bolts in sequence (1), (2), and (3) to 22 N·m (16 lb ft).
