For 1990-2009 cars

#### Tools Required

J 36660-A Torque Angle Meter

1. Install the flywheel to the crankshaft. Align the flywheel-to-engine marks.

Notice: Apply the proper amount of the sealant to the fastener when assembling this component. Excessive use of the sealant can prohibit the component from being assembled properly or allow the fastener to loosen. A component or fastener that is not assembled properly can loosen or fall off leading to extensive engine damage.

2. Apply GM P/N 12345493, or the equivalent, to the flywheel retaining bolt threads (1).

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.

3. For vehicles equipped with an Automatic Transmission, install the flywheel retaining bolts (1-8) to the crankshaft.

Tighten
Tighten the 8 flywheel retaining bolts in the sequence shown for Automatic Transmission to 83 N·m (61 lb ft).

4. For vehicles equipped with a Manual Transmission, install the flywheel retaining bolts to the crankshaft and torque the bolts in 2 steps.

1st Step-Tighten
Tighten the eight flywheel retaining bolts in the sequence shown for Manual Transmission to 49 N·m (36 lb ft).

5. Perform the final torque on the manual transmission flywheel retaining bolts.

2nd Step-Tighten
After the proper torque of 49 N·m (36 lb ft) has been reached, use a J 36660-A and tighten the flywheel bolts an additional 90 degrees.
