### Installation Procedure

1. Refer to the serpentine belt routing diagram to install the serpentine drive belt.

Important: Ensure the serpentine drive belt is aligned into the proper grooves of the drive pulleys.

3. Reposition the AIR injection crossover pipe (4).
4. Install the AIR injection crossover pipe to the rubber hose connections (2).
5. Install the AIR injection crossover pipe clamps to the rubber hose connections.

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.
