• Q: How to service the Denso G3A alternator on 2001 Cadillac DeVille?

  A: Service operations for the denso g3a generator begin by disconnecting the battery negative cable followed by removing the auxiliary Drive Belt. Access to the auxiliary generator requires removal of its wiring harness connector together with the protective boot from the bat terminal. Unscrew the bat terminal nut of the auxiliary generator output and disconnect its positive lead. Start by removing the surge tank mounting nuts and bolt followed by removing the overflow hose retainer from the strut tower mounting stud. Reach the mount of the auxiliary generator after moving the surge tank securely aside where the generator has three shims positioned between itself and the front of the generator bracket. Start by removing bolts (1, 4) and the nut from the mounting points for the auxiliary generator. Afterward, extract the generator from the motor vehicle. Position the auxiliary generator on the engine while installing the three shims between generator and bracket front before securing the generator with bolts (1, 4) and nut. First mount the surge tank with all studs presenting while directing the overflow hose through the retainer toward the strut tower. Secure the retainer piece at the mounting stud next to the strut tower. Screw and bolt the surge tank mounting nuts before tightening them with 6 n.m (53 lb in) torque. Secure the auxiliary generator wiring harness connector point to point after connecting the battery positive lead, finish by affixing and tightening the auxiliary generator output bat terminal nut to 10 n.m (89 lb in). Finish the installation by using a protective boot to cover the auxiliary generator output bat terminal followed by Drive Belt installation and Battery Cable connection.
