Hi,

This isn't a traditional job. On this vehicle, you will need to remove the cooling fan assembly and the A/C will need evacuated to remove a flexible low-pressure line. Then the system will need to be recharged after the new alternator is installed.

If you look below, I provided the removal and installation directions specific to this vehicle. Take a look through them and let me know if you have questions.

Let me know if this helps.

Take care,

Joe

That one is not that bad but you need to be able to recover the refrigerant charge so you can move the low-pressure line out of the way to get room to remove it.
Step one is to remove the cooling fan from the front, then remove the serpentine belt. Now remove the belly cover from under the front end. Recover the refrigerant charge, then the low-pressure line and plug the opening to keep dirt out of the compressor. Now you can disconnect the battery cable from the battery and the alternator, then unplug the connector. Now remove the retaining bolts and remove the alternator. Reverse the process to install it. Use a new O-ring on the low-pressure A/C line and lube it with some refrigerant oil for assembly. Be careful tightening the battery cable nut on the B stud on the alternator, they can be damaged easily. Then pull a vacuum in the A/C system and recharge it with 1.21 pounds of R134A. Test the system for operation.
