I was able to get the car out of the sun and have a look under the hood.

With the car running and the AC on I could see that the AC belt had lost it tension. That makes sense because since replacing the belts the AC had not been used very much. With a 600 mile drive it had stretched a bit.

I had the tools needed to address the problem. However before I had moved it enough to give it the proper tension I ran out of adjustment. It simply would not go any further. The solution will be to get a shorter belt and install it.

The belt that was on there was a Conti that was purchased for this application six months ago at FCP, but the adjuster ran out of slot on the bracket.

… and yet another update
I had another belt in the trunk that was shorter and I was able to get it on. It was a 950 while the one that was too long was a 975. Checking on FCP the one that is listed for this application (currently) is a 968.
