Generator Replacement 3.1L

Removal Procedure

The Delphi CS130D (K68) 105 ampere generator is serviced as a complete unit only.

  1. Disconnect the battery negative cable. Refer to Battery Negative Cable Disconnection and Connection .
  2. Remove the drive belt from the generator. Refer to Drive Belt Replacement in Engine Mechanical - 3.1L.
  3. Place the coolant recovery reservoir aside for access. Refer to Coolant Recovery Reservoir Replacement in Engine Cooling.

  4. Object Number: 302473  Size: MH
  5. Remove the bolts (1,2,3) from the generator.
  6. Disconnect the electrical connector from the generator.
  7. Position aside the protective boot from the generator output BAT terminal.
  8. Remove the generator output BAT terminal nut and disconnect the battery (positive) lead from the generator.
  9. Remove the generator.

Installation Procedure

  1. Position the generator to the engine.
  2. 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 battery (positive) lead and the generator output BAT terminal nut.
  4. Tighten
    Tighten the generator output BAT terminal nut to 20 N·m (15 lb ft).

  5. Press the protective boot on to the generator output BAT terminal.
  6. Install the electrical connector to the generator.
