  Q: How to replace the alternator on Cadillac Catera?

  A: Begin the Alternator replacement by first disconnecting the negative Battery Cable followed by removing the intake air resonator. Begin by removing the Drive Belt followed by raising the vehicle to work on it. Begin by detaching the cooling duct from the generator duct cap while removing the terminal nut of the field coil and its connecting lead from the generator. The Battery Cable's positive nut also needs removal before extracting its corresponding cable from the generator. You must remove these assembly elements: generator upper mounting nut , generator lower mounting nut, and generator through bolts (1,2). Start by lowering the vehicle and then uninstall both the generator and generator cooling duct cap screws along with the generator cooling duct cap itself. Place the generator cooling duct cap first then install its cap screws until torque reaches 1 n.m (9 lb in). Under vehicle elevation, position the generator into its installation position and install the generator through bolts (1,2). First tighten the generator lower mounting nut to 40 n.m (30 lb ft) before securing the generator upper mounting nut to 40 n.m (30 lb ft). Secure the positive Battery Cable to the generator through its dedicated cable nut and tighten it to 8 n.m (71 lb in). Proceed by connecting the generator with the field coil terminal lead while securing it with the field coil terminal lead nut then tighten to a torque of 3.5 n.m (31 lb in). Begin by reconnecting the generator cooling duct to the generator cooling duct cap. Lower the vehicle then reinstall the Drive Belt and intake air resonator before attaching the negative Battery Cable.
