Generator Replacement 2.2L

Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

1. Disconnect the battery negative cable.
2. Remove the drive belt. Refer to Drive Belt Replacement in Engine Mechanical - 2.2L.



3. Working through the wheel well, remove the generator rear brace from the engine.

•	Remove the generator brace to the engine block bolt.

•	Remove the generator brace to the intake manifold nut.

•	Remove the generator brace to the engine stud nut.




4. Disconnect the generator electrical connector.



5. Remove the generator output (BAT) terminal nut and wire.



6. Remove the generator mounting bolts.
7. Remove the generator from the vehicle.

1. Install the generator to the vehicle.

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.

2. Install the generator attaching bolts.

Tighten

1. Tighten the rear generator bolt to 50 N·m (37 lb ft).
2. Tighten the front generator bolt to 25 N·m (18 lb ft).



3. Install the generator output (BAT) terminal feed wire and retaining nut to the generator.
