I have a 2000 Altima GXE with about 65,000 miles. Having owned an Accord prior to this I know the importance of changing the timing belt in a timely fashion. My manual maitenance schedule refers to changing the timing belt at 105,000 but has a footnote that says something like "Pathfinder, Frontier only" (maybe some other models, too, but no Altima). There are no other references to a timing belt change. This would lead me to believe that it uses a timing chain instead of a belt, but everything I have read says that Nissan did not go to a chain until 2002. So two questions, does my 2000 have a timing belt or a timing chain, and if it is a belt, when should it be changed? Thanks for anything that someone might have on this issue.
