Is your current belt gone....?? If it is still there, you will find a series of numbers on the belt...one represents the length. Replace it with a like belt. Most of the brands out there will be good.

Thanks
The current belt is still working. Car has about 46k miles. Took it in yesterday for state inspection (it passed) but it was recommended to have the belt replaced. Owners manual says replace at 60k..?
I plan to do a visual inspection on the belt myself today. If I order the belt I'm wondering how difficult it is to do the job yourself? Most say it's not hard if you have the right tool.

No special tools really needed, but they do make a serpentine belt tool that makes it slightly easer to move the idler pulley.
Do a google search for idler tension pulley tool and you'll see lots of options.
But I didn't use one. I just used a breaker bar and socket (not sure what size now).
In the picture I posted above, you can see the idler pulley with the arrow.
That pulley is spring loaded, and you raise it up in the direction of the arrow.
This removes all tension on the belt and it slips right off.
Pay close attention to the routing diagram when placing the new belt on, once again raising the idler pulley.
If you find it difficult to get the belt over any of the pulleys, double check you have it routed correctly.
If it is not routed correctly, you won't be able to get it over the last pulley.
