• Q: How to replace the alternator with AWD on 2005 Cadillac STS?

  A: The first step to replace a generator with awd involves disconnecting the negative Battery Cable followed by generator Drive Belt removal. After removing the upper generator mounting bolts (1,3) you should lift and support the vehicle before proceeding. Begin by removing the front air deflector along with front wheels and right side wheelhouse liner from the vehicle. The generator becomes accessible when you drop the stabilizer shaft links from both sides of the lower Control Arm before rotating the shaft downward. From the wheelhouse opening finish the removal procedure by cutting the wiring harness tie strap then remove the lower generator bolt for mounting bracket access so you can lift off the generator to reach both connector and generator output bat terminal nut. Before generator removal, the wire harness connector should disconnect while the protective boot moves away from the generator output battery terminal and the terminal nut needs removal before disconnecting the generator battery positive lead. Position the generator in its intended location then attach the battery positive lead before tightening the generator output battery terminal nut to 10 n.m (89 lb in). Install the protective boot onto the bat terminal of the generator output then ensure the wiring harness connector is attached before mounting the generator onto its bracket that affixes to the engine. Walk away from the lower generator bolt without tightening it while lowering the vehicle before installing the upper generator bolts one at a time to a torque of 50 n.m (37 lb ft). After raising and supporting the automobile reinstall the wiring harness tie strap around the generator and proceed with installing stabilizer shaft linkups to the lower control arms and right-side wheelhouse liner and front wheels and front air deflector. To finish the repair, lower the vehicle before you install the Drive Belt on the generator and reconnect the battery negative terminal.
