I have had a rattle noise coming from the alternator/fan area which has got progressively worse. It now is almost constant and gets louder with RPM. I have investigated this evening and the water pump pulley has a lot of play. The alternator, A/C compressor, and adjustment pulley/bearings all seem to be fine and smooth.
Would this likely be some loose bolts fastening the pulley to the water pump or something worse? What's the easiest way to get to this, take the radiator out?
Here is a video to show the rattle:
