Hello Guys/Gals. I'm about to buy both belts to replace on my Wife's 2003 Nissan Maxima, but I was wondering, should I also be changing the Idler Pulley as well? Thank you for your help.

 

Do a search and read up on the idle pulley i would say about 80% of the time its going to snap.and remember its reverse thread.

 

I did a search on belts and I did read about the threads being reversed. I also saw a picture one that looked completely shredded (not sure how). I figured I SHOULD change it but I wasn't positive. Thank you. I also decided that I will be going with either a Gates Belt or Gatorback. Never had problems with Gatorback I must say. Might as well go with a Goodyear pulley too.
