• Q: How to replace the alternator on 2004 Buick LeSabre?

  A: In order to replace the generator (L36), you would remove the Drive Belt and take off the battery negative cable. Next, remove the fuel injector sight shield and the screws that hold the generator brace and then the brace itself. The wiring harness connector from the generator will be disconnected and the protective boot from the generator output bat terminal repositioned for access. Unscrew the bat terminal nut off the generator output and unhook battery positive lead from the generator and after that, remove the bolts holding the generator on the vehicle to remove the generator from the vehicle. For installation, mount the generator to the engine and tighten the mounting bolts with the torque of 50 n.m (37 lb ft). Making the connection between the wiring harness connector and the generator, then the positive lead, and then the generator output bat terminal nut should be installed and tightened to 12.5 n.m (111 lb in). Reinforce the generator by applying the protective boot to the generator output bat terminal, install the generator brace and the fasteners against 50 n.m (37 lbs. Ft) and brace on 25 n.m (18 lbs. Ft.). Finally, reinstall the fuel injector sight shield, Drive Belt and bring back the battery negative cable.
