Installation Procedure

WARNING: This page is about a different car, the 2003 Oldsmobile Bravada, 2003 GMC Envoy XL, 2003 GMC Envoy, and 2003 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT:

When installing the center seat belt anchor to the seat belt buckle/anchor plate assembly, ensure that the center seat belt webbing is not twisted.
Ensure that the center seat belt anchor is properly indexed between the locating tangs on the seat belt buckle/anchor plate assembly.

Position the center seat belt anchor to the seat belt buckle and anchor plate assembly.
NOTE: 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.
Install the center seat belt anchor bolt that retains the center seat belt anchor to the seat belt buckle/anchor plate assembly. Tighten the bolt finger tight.
Position the seat belt buckle/anchor plate assembly to the rear seat back hinge bracket.
