- Remove the serpentine drive belt tensioner bolts.
- Remove the serpentine drive belt tensioner.
- Remove the front timing belt cover bolts.
- Remove the front timing belt cover.
- Remove the transfer wiring harness channel.
- Inspect the sealing strip on the outer edge of the front timing belt cover for cracks and/or tears.
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.
Important: Use caution when releasing the retaining tabs to reduce the risk of breakage when removing the wiring harness channel cover.

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.
