The triangle bracket is in the wrong place. It is supposed to attach to the two water pump bolts and the unused hole in your pic attached at the front of the alternator.
Here is a pic the (not correct it is a mock up of a bracket for a GM alternator) but gives an idea of how the bracket should be attached to the water pump. On your car it will line up with one of the holes at the top of the head, not the lower hole shown here.
