You will need to use a 14mm socket and ratchet to loosen the tension pulley on the serpentine drive belt system.

Use some sort of extension bar to give you more leverage. In my case, I used 3/4” PVC pipe and pull towards you. Pull with one hand and hold to release the tension in the pulley while you remove the belt from the top large pulley. Go all the way down and remove the belt from the remainder of the pulleys and pull the old serpentine belt out.
