Take each belt off and run the car for half a minute to narrow down the source of the noise.
Doubt if it's the water pump. They don't normally whine.

It's not the missus is it?

hope you get it sorted...i have a mid-high pitched whine coming from the front of my engine, mine sounds like its coming from the camshaft flywheel, maybe a bearing. be interested to hear what you find wise.

ive taken off the belts and no noise. put the alternator belt back on, noise coming from water pump... just got to get a water pump and see if its gone.

have you recently fitted a cam belt and idler ....if the idler has been tensioned up to tight the belt can whine a bit or maybe its time to do a cam belt before it goes on you

Noise goes when the alternator/pump belt is removed, so it's not the cambelt.
However, I'd recommend changing the cambelt when the water pump is replaced, as the tensioning spring locates against the water pump.

i fitted a cam belt 3 months ago, tensioner but not spring. the cam belt tensioner is noisy. so ive replaced the cam belt, tensioner, spring and water pump.. Noise is still here!!!!!!!!!!!!!! any surgestions
