Top, can you post the bearing number here? It would be helpful.
Be glad to. It uses a common 6203-2RS bearing. The factory bearing has NSK 6203 DUL1 embossed on the seal. Do yourself a favor and buy a quality bearing, however. I work at a manufacturing plant, and occasionally some cheap bearings get past engineering, which creates a bit of havoc in the field.
I have had exactly the same issue a week ago. the issue was indeed a bearing in the idler tension pulley, water pump had a little play but was not causing the noise. Have spent £126 on a new honda water pump which is now fitted and £5 on the bearing for the tensioner which we pressed out at my mechanics garage.
Have the old water pump which is really probably fine and im guessing would be as new if the bearing in it was replaced too. Anyone on here need one? open to offers.
Also i think ive lost 20mpg from 70 to 50 from when i got the new waterpump fitted and can this be caused by an over tensioned belt?

Get an automotive stethoscope from autozone, harbor freight. It'll be easy to tell where exactly the sound is coming from.
Old school method: Use a small diameter vacuum hose, stick one end of the hose in your ear and hold the other end on the suspected noise area. I also use a very small metal funnel on the engine end of the hose.
