- Clean the drive belt surfaces and accessory drive pulleys.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

- Rotate the drive belt tensioner clock-wise with a 15 mm wrench.
- Route the drive belt over the top of the water pump pulley last.
- Release the drive belt tensioner and recheck the drive belt for proper seating in the accessory drive pulleys.
- Reposition the AIR injection crossover pipe (4).
- Install the AIR injection crossover pipe to the rubber hose connections (2).
- Install the AIR injection crossover pipe clamps to the rubber hose connections.
- Install the AIR injection crossover pipe bushing nut (6) to the generator bolt.
- Use a wrench to counterhold the generator bolt on the back side of the generator to tighten the AIR injection crossover pipe support bracket nut to the generator bolt.
- Install the A/C compressor hose strap bolt (1).
- Install the splash shield.
- Install the splash shield bolts.
- Lower the vehicle.

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.
