Removal Procedure

CAUTION: To avoid any vehicle damage, serious personal injury or death when major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed.

Installation Procedure




1. Install the crossmember to the vehicle.
2. Perform the following procedure before installing the bolts.
- Remove all traces of the original adhesive patch.
- Clean the threads of the bolt with denatured alcohol or equivalent and allow to dry.
- Apply Thread locker GM P/N 12345493 (Canadian P/N 10953488).

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.
