Generator Replacement 2.2L

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 negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
  2. Remove the drive belt. Refer to Drive Belt Replacement in Engine Mechanical - 2.2L.
  3. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.

Installation Procedure


    Object Number: 43042  Size: SH
  1. Install the generator to the vehicle.
