my 89 325i is making a really loud squealing noise and i cant tell what it is. the belts are still good and seem tight and when i rev the motor up it will go away but once the motor comes to idle or if im coming to a stop it will slightly squeal sounds kinda like a bad bearing or somthing and then when i go to accelerate it gets horribly loud until a certain rpm when it goes away completely. could it be my fan clutch?

Yes. Water pumps go bad from time to time. Cross the P/N on realoem for the waterpump. I don't see why M20 pumps wouldn't cross...but just in case.
I would do the timing belt while in there, unless it was done very recently...in which case the waterpump should have been replaced....while in there.1974.5 Jensen Healey : 2003 330i/5

Remove all of the v-belts from the engine and see if the noise is still present. You won't hurt the engine by running it with no water pump for a minute or so with the engine cold. If the noise is gone, check each or the rotating parts for bad bearings. If the noise is still present with the belts off, the cause is the idle pulley on the timing belt tensioner.The car makes it possible, but the driver makes it happen.

thanks for the help guys... im gonna try removing the fan then the belts and see if the noise is still there hopefully it is something simple.

one more thing, is your 850i 6sp as fast as i'd imagine? being V12 and 6 sp?
