The car has air con but I suspect that the cause of the auxillary belt failure was a chip out of the crankshaft pulley which neatly cut away one edge of the belt. The tensioners all felt ok (I checked these closely after reading the posts on this forum about previous failures).
Your tensioner is buggered! A chip DOES NOT wear a grove off the side, the worn tensioner does!!
When you get her running again and back together, LOOK at the tensioner with the engine running and see the angle it is sitting at, Id be pretty sure IT had dug the groove!!! Seriously!! GET IT CHANGED!!!
