This is why I carry a spare pulley and belt when I travel. The repair is straight forward and I can get back on the road easily. It helps to have a long 18mm combination (open end-box end) wrench to reach the tensioner bolt. It is harder to get the bolt with a socket wrench.
The only problem is the engine is HOT and I got a couple of burns this time. Even with gloves on, you have to reach in among the coolant piping. I have added heat resistant sleeves to my travel tool box.

Hi Jim ........Your pulley(s) that failed were stock pulley(s) rather than the Tensioner Aluminum Pulley Locobob had fail. Great Photos...... and that was one reason I went to the Aluminum Pulley as the Bearing is easy to replace.
It still appears like a Fatigue Failure of the Aluminum Tensioner Pulley as Phil suggested. If no other type of interference or bearing failure is found by Locobob.
I also have the Water Pump Aluminum Pulley which has no belt retaining ridge making it much easier to remove the Serpentine Belt (back of belt rides on pulley) from that Water Pump Aluminum Pulley first.
I did modify the 18mm combination wrench heating and bending the box end straight making it much easier to use the box end on the Tensioner 18mm Bolt.
