Detach the cable from the negative terminal of the battery and remove the electrical connectors from the alternator. Many new and rebuilt alternators may not come with a pulley, so if purchasing one, check the shop's policy regarding pulleys, as some may offer this service for free. If you need to switch the pulley yourself, loosen the pulley bolts before removing the drivebelt. Next, loosen the alternator adjustment bolt and raise the vehicle to loosen the pivot bolt while supporting the alternator. Detach the drivebelt, then remove the adjustment and pivot bolts to separate the alternator from the engine. If necessary, remove the pulley. When replacing the alternator, take the old one to ensure the new or rebuilt unit matches in appearance, terminal configuration, and identification numbers. If needed, install the pulley on the new or rebuilt alternator, and then proceed with installation in reverse order of removal. After installation, adjust the drive belt tension and check the charging voltage to verify proper operation of the alternator.
