Installation Procedure

    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.

  1. Install the torque converter to the flywheel with the attaching bolts.
  2. Tighten
    Tighten the bolts to 56 N·m (41 lb ft).

  3. Install the starter. Refer to Starter Motor Replacement .
  4. Start the engine and check for vibration. Repeat the procedure until the best possible balance is obtained.
