Serpentine belt came off. Looking at the diagram for putting the belt back on I am missing the tensioner. It must have broke off.

The tensioner is secured to the engine via bolt #11 (8mm allen).

On the back of the tensioner is a "locating dimple" which allows
for correct placement of the tensioner.

Actually, it might even be a 10mm allen head bolt... it's been a
while since I had to remove one.
