One of the pulleys on my 2008 Patriot is beginning to squeak. It's hard for me to tell which one needs replaced. What's the best way to identify the squeaky culprit? Is there one that is more likely to go bad? My Patriot has 184K miles on it.

You can try a mechanics stethoscope, a long screwdriver, wooden dowel, etc. to carefully probe around the pulleys while it's running to see where the sound is the loudest.

Probably the tensioner.
