Disconnect the cable from the negative terminal of the battery. Raise the vehicle and support it securely on jackstands. Remove the lower splash shield beneath the alternator (if equipped) and the right-side inner fender splash shield. Remove the drivebelt. Disconnect the electrical connector and the alternator output wire from the alternator. Remove the engine cooling fan and shroud. If you're working on a 2004 and later model, remove the radiator. Remove the air conditioning compressor mounting bolts (without disconnecting the refrigerant lines) and slide the compressor forward. This step is not necessary on 2005 and later models, unless it improves access. Remove the alternator mounting bolts and remove the alternator from the engine. Installation is the reverse of removal. Install the drivebelt and reconnect the cable to the negative terminal of the battery. Adjust the drivebelt.
