Hello, I'm Danny.
No, you will not have to take the tensioner off. Simply using a serpentine belt tool you will move to tensioner clockwise to release pressure off of the belt. You will the move tensioner again clockwise to be able to install new belt. The tensioner is spring loaded so it will take some effort to move. Here is a tutorial showing how to replace a serpentine belt:
I've attached a belt diagram below for your car so you will know how to route in case you forget. Hope this helps and thanks for using 2CarPros.
