Generator Replacement L47

The Delphi AD237 (KG7) 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. Refer to Drive Belt Replacement in Engine Mechanical-4.0L.
3. Remove the radiator. Refer to Radiator Replacement in Engine Cooling.



4. Disconnect the wiring harness connector from the generator.
5. Reposition the protective boot from the generator output BAT terminal for access.
6. Remove the generator output BAT terminal nut and disconnect the positive lead from the generator.



7. Loosen the lower generator bolt (3).
8. Remove the generator bolts (1, 2) from the generator.
9. Remove the generator from the vehicle.

1. Position the generator to the A/C compressor and engine.

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.
