Installation Procedure

WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Add threadlock GM P/N 12345493 to the new flywheel bolts.
  2. Install the flywheel and secure the flywheel with the new bolts.
    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.

    Tighten 

    1. 2.1. Tighten the bolts in sequence to 25 N.m (18 lb ft).
    2. 2.2. Use the J 36660-A in order to tighten the bolts an additional 50 degrees.
