My serpentine belts for my 91 Nissan maxima are worn and squeak loudly I just purchased the belts and found they are a lot harder to replace then I thought anyone know how to replace the air conditioner belt , water pump belt, and the alternator belt ?

 

techincally a serpentine belt is one belt for everything, with a spring-loaded tensioner arm... like this http://autorepair.about.com/library/...s/42163954.gif

we just have "belts".

anyways, MA-8 or MA-14 depending which engine you have. http://www.nicoclub.com/FSM/Maxima/1994/ma.pdf
