For 3.2L V6 engines, remove the intake air duct mounting fasteners. Remove the alternator mounting fasteners and disconnect the alternator B+ terminal nut and electrical connector. Remove the alternator. For 2.8L, 3.0L, and 3.6L V6 engines (2007 and earlier models), install an engine support fixture or engine hoist. Disconnect the Battery Cable from the alternator and disconnect the electrical connector from the alternator. Disconnect the electrical connector to the Electronic Brake Control Module (EBCM) and remove the engine mount lower nuts. Remove the alternator lower mounting bolts and raise the engine enough to access the upper mounting bolt. Remove the upper mounting bolt and remove the alternator. For 2008 and later models, disconnect the battery cable from the alternator and disconnect the electrical connector from the alternator.

Installation is the reverse of removal. Reconnect the cable to the negative terminal of the battery and check the charging voltage to verify the alternator is operating correctly.
