2007 Buick Lucerne Parts Questions & Experts Answers

• Q: How to replace the alternator (RPO L26) on 2007 Buick Lucerne?

  A: Start by disconnecting the negative Battery Cable followed by removing the intake manifold cover along with the Drive Belt. After disconnecting the negative Battery Cable you must eliminate the generator brace bolt and nut and generator brace in succession. The first step is to disconnect the engine harness electrical connector from the generator before repositioning the starter cable boot and removing the generator terminal nut and starter cable from the generator. Start by disassembling the generator front bolt followed by removing the generator rear bolt and stud before completing the generator removal. You should begin generator installation by placing it into position on the engine then screw in the generator front bolt followed by the generator rear stud and bolt before tightening the bolt/stud to 50 n.m (37 lb ft). After connecting the starter cable to the generator, torque the generator terminal nut to 20 n.m (15 lb ft). Begin by placing the starter cable boot while connecting the engine harness electrical connector to the generator. Then install the generator brace and its corresponding bolt and nut making sure to tighten the bolt to 25 n.m (18 lb ft) and the nut to 50 n.m (37 lb ft). The process ends with placing the Drive Belt along with the intake manifold cover and reattaching the negative Battery Cable.
