Hello,

To get the belts out you will have to turn the belt tensioner, this will loosen the belt and you can remove it.
Keep in mind to have a mental diagram of how the belt routes. You can also take a picture of the routing of the belt before removing the old one.
It will make the task easier if you can get a serpentine belt tool. Those tools you can 'rent' from your local auto parts store.

Here is a helpful guide:

I have attached the replacement instructions below.

Please let me know of any questions.
Thank you.
