#### Tools Required

• | J 36660-A Torque Angle Meter

• | J 38122-A Harmonic Balancer Holder

1. Install the flywheel.
2. Install the retainer if the vehicle has an automatic transmission.

Notice: This bolt is designed to permanently stretch when tightened, and therefore MUST be replaced anytime it is removed. The correct part number fastener must be used to replace this type of fastener. Do not use a bolt that is stronger in this application. If the correct bolt is not used, the parts will not be tightened correctly. The system or the components may be damaged.

3. Install the new bolts or apply Adhesive/Sealant Compound GM P/N United States 12345493, GM P/N Canada 10953488 or the equivalent to all flywheel to crankshaft bolts that are being re-used. Carefully follow the instructions included with the thread locking compound in order to ensure proper bolt retention.

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.

4. Holding the crankshaft balancer with the J 38122-A , tighten the bolts evenly.

Tighten
Tighten the bolts to 30 N·m (22 lb ft). Use the J 36660-A in order to rotate the bolts 45 degrees.
