Tools Required

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable.
2. Remove the accessory drive belt. Refer to Drive Belt Replacement .
3. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
4. Remove the right splash shield.



5. Remove the balancer retaining bolt and the washer using J 38122-A to prevent crankshaft rotation when loosening the bolt.
6. Remove the balancer assembly using J 24420-B .

1. Lubricate the front seal and the sealing surface of the balancer with Chassis Grease GM P/N 1051344 or equivalent.

Important: The automatic transmission crankshaft balancer must not be installed on a manual transmission equipped engine.

2. Install the balancer onto the crankshaft indexing keyway. Tap into place using a rubber or sand-filled mallet.

Notice: Do not use the J 36660 Torque Angle Meter to rotate the retaining bolt an additional 90 degrees. The torque capacity of the tool will be exceeded and damage to the tool will result.

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. Install the retaining bolt and the washer.

Tighten
Tighten the bolt to 175 N·m (129 lb ft) while using J 38122-A to prevent crankshaft rotation. Put a mark on the socket next to one of the four marks on J 38122-A This mark will represent the 0 degree point. Tighten the bolt by rotating the socket clockwise 90 degrees. At 90 degrees the socket will index with the next mark on the tool.

4. Install the right splash shield.
5. Lower the vehicle.
6. Install the accessory drive belt. Refer to Drive Belt Replacement .
7. Connect the negative battery cable.
