Removal Procedure

    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 battery negative cable.
  2. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.

Installation Procedure

    Object Number: 258322 Size: SH

    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. Connect the starter motor field leads to the starter motor as follows:
    2. 1.1. Loosely install the starter enable relay lead (1) to the starter solenoid terminal.

    Align the terminal retaining tab to the starter solenoid.

    1.2. Loosely install generator output (BAT) lead (3) and the battery positive cable (2) to the solenoid terminal.

    Align the battery positive cable terminal retaining tab to the starter solenoid.

    Tighten

        • Tighten the starter enable relay lead nut to 2 N·m (18 lb in)
        • Tighten the battery positive cable nut to 19 N·m (14 lb ft)

    Object Number: 7306 Size: SH
  2. Install the two starter motor mounting bolts and the shims (if necessary) through the starter to the engine.

    3. Tighten
    Tighten the bolts to 43 N·m (32 lb ft).
