how do you replace a serpentine belt on a 2004 nissan sentra 2.5 litre engine?

Q:

A: You don't need to do anything with the motor mounts. You need to loosen the belt tensioner for the alternator. Then you need to loosen the power steering belt tensioner. You will probably want to get the car up high enough to get to the tensioners. It's easier that way.
