im curious about this too.
does your jeep have A/C?
this is all i could gather googling it and searching for it - if it has ac, the tensioner should be on the alternator. if theres no a/c it should be on the power steering pump.
thats pretty much all the info i could gather.
i tried to change the belt on mine and it was a pain. i gave up, because i had alot of repairs to do on my tj.
the new belt is actually sitting in my garage still lol.
all i could find as far as a tutorial is to loosen a hella bunch of bolts and i guess pry the tensioner if its stuck.
its not an automatic tensioner.
so yeah anyone willing to point us in the direction of a good how to with pics, or at least give us a good explanation..
