• Q: How to replace the alternator on 2002 Buick LeSabre?

  A: The generator replacement process starts with Battery Cable disconnection then Drive Belt removal. First remove the fuel injector sight shield and fasteners holding the generator brace while removing the brace from the system. The generator needs its wiring harness connector detached while you move the protective boot away from the bat terminal output of the generator to work. Follow these steps to remove the generator from your vehicle: first unscrew the generator output bat terminal nut and disconnect the battery positive lead from the generator next remove the generator mounting bolts allowing you to extract the generator from your vehicle. After positioning the generator correctly on the engine start installing its mounting bolts by tightening them to 50 n.m (37 lb ft). Plugin the generator wiring harness connector before you attach the positive lead to the generator output bat terminal. Finish by installing and tightening the generator output bat terminal nut to 12.5 n.m (111 lb in). Set the generator output bat terminal into the protective boot before adding the generator brace and tightening the brace nut to 50 n.m (37 lb ft) while the brace bolt requires 25 n.m (18 lb ft) torque. Reconnect the battery negative cable while finishing installation with the fuel injector sight shield and Drive Belt.
