• Q: How to replace the Denso G3A alternator on 2004 Cadillac DeVille?

  A: The denso g3a generator replacement process starts by disconnecting the negative cable of the battery followed by removing the auxiliary Drive Belt. The process starts by disconnecting the wiring harness connector from the auxiliary generator to make room for redistributing the protective boot from the bat terminal of the auxiliary generator output. Start by removing the auxiliary generator output bat terminal nut and breaking the connection to its positive lead. Discard the surge tank mounting nuts and bolt followed by taking off the overflow hose retainer from its bracket at the strut tower. Safely push the surge tank to one side to reach the mounting bolt for the auxiliary generator. Remember that you will find three shims which run between the auxiliary generator and its bracket in front position. First remove the auxiliary generator mounting bolts (1, 4) and nut before taking the auxiliary generator out of the vehicle. Place the auxiliary generator in position then insert three shims between the bracket front and generator before securing everything with generator bolts (1, 4) and nut. After placing the surge tank onto its mounting studs, run the overflow hose through the retainer and mount the retainer to its corresponding stud at the strut tower. Tighten surge tank mounting nuts along with their bolt to 6 n.m torque (53 lb in.) specification. Secure the auxiliary generator output bat terminal with a nut that requires a torque value of 10 n.m (89 lb in) before connecting the battery positive lead and attaching the wiring harness connector to the auxiliary generator. After installing the protective boot over the auxiliary generator output bat terminal you should position the auxiliary Drive Belt then reconnect the battery negative cable.
