How do I replace a serpentine belt on a Nissan Sentra?

Answer by  NateB (571)

You need to locate the tensioner pulley. Using a socket wrench, pry on the bolt in the center of the tensioner pulley to aleviate the tension on the belt and remove the belt. To install the new one do the same thing, making sure the belt is installed the same as the old one was.

It's a pretty strait forward process although a messy and greasy one. You'll need the proper sized belt which can be purchased from any autoplace. Get a rag.
