Yep those can be a little tight. You will need to remove some brackets and the radiator mount so you can bring the alternator upward and out. Start be disconnecting the battery and then removing the serpentine belt.

Here are some guides and diagrams (below) to help you get the job done.

you should test it after it is done.
