• Q: How to replace the Denso SC1 (KG9) alternator on 2003 Cadillac DeVille?

  A: The replacement process for denso sc1 (KG9) generator starts by removing power from the battery negative terminal along with the Drive Belt followed by the Radiator disconnection. Start by disconnecting the wiring harness connector from the generator before securely resting the protective boot away from the generator output bat terminal to access it. Detach the generator output bat terminal nut followed by removing its positive lead. The replacement process begins with loose fitting the lowest generator bolt followed by bolt removal (1, 2) before extracting the generator from the vehicle. Install the generator in place between the A/C Compressor and engine by tightening generator mounting bolts (1, 2) to 50 n.m (37 lb ft). The wiring harness connector needs to be connected to the generator as you add the battery positive lead and install the generator output bat terminal nut with torque set at 12.5 n.m (111 lb in). First reinstall the Radiator while pressing the protective boot onto the generator output bat terminal. After that install the Drive Belt before reattaching the battery negative cable.
