• Q: How to replace the alternator on a LH2 with AWD on 2008 Cadillac STS?

  A: The negative Battery Cable must first be disconnected to exchange the lh2 generator with awd. Remove first the generator Drive Belt as a next step in the process. Before working on the vehicle users should first detach the upper generator mounting bolts (1,3) and elevate the car for better access. Start by first removing the front air deflector then the front wheels and finally the right side wheelhouse liner. Lower Control Arm stabilizer shaft links at both sides must be detached along with downward shaft rotation to reach the generator component. The generator wiring harness connects to the wheelhouse opening where you should cut the tie strap before proceeding with the removal operation. The generator becomes accessible when the lower mounting bolt comes off to lift it off its bracket for revealing both the connector and the generator output bat terminal nut. First detach the wire harness electrical connector then move the generator output terminal boot out of place before removing the generator output terminal nut that disconnects the battery positive lead. Take the generator off the vehicle as the last step. When installing the generator position it in its intended site and connect the battery positive wire to the device before torquing the generator output terminal nut to 10 n.m (89 lb in). Position the generator output bat terminal's protective boot while you connect the wiring harness and place the generator onto its engine bracket. Secure the lower generator bolt yet maintain loose connection before lowering the vehicle physically. Finally replace and secure the upper generator bolts in order with a torque of 50 n.m (37 lb ft). Lift the car for another round to attach new wiring harness tie straps on the generator before securing stabilizer shaft links at both sides on the lower Control Arm. Put back in place both side wheelhouse liners and front wheels as well as the front air deflector before lowering the vehicle. Finish up the process by installing the generator Drive Belt along with reattaching the battery negative cable.
