Noisy loud squeak, rumbling and buzzing sound

Yoo I recently changed my belts in my 1987 bmw 325e because of a loud noise coming from the front area, wanted to know what exactly it was, because that sound is still occuring thanks alot here is a video below...I also sprayed down the fan clutch and what it connects to with wd-40 and you can here the change but reverts back to the noise.

mine was making this noise as well..take the fan and fan clutch off and see if its makes any noise when you turn it by hand or if theres any play in the bolt..may just be a bad fan clutch..if it is buy a new one or find someone parting out and see if they have one in good condition..thats what i did and smooth sailing for me...o and another good way to tell if its bad would be roll up a newspaper and stick it in the fan and see if it stops really easy i say this because it looks like you fan isnt moving very quick may just b the video

That sounds like a bad bearing. It could be the water pump, fan clutch, alternator, or timing belt tensioner. With the engine stone cold remove the alternator/water pump belt and see if the noise is still present (don't run the engine over a minute). If the noise goes away it is from the timing belt. Otherwise it is from the alternator, water pump or fan clutch.

Thats the thing, I just had my local bimmer shop replace it because I didnt have the tools..It ran smooth and quite for a steady month, now noise.

Just anything steady you can stick in there that isn't your hand... newspaper is good because it gives and doesn't brake the fan if indeed the fan does want to keep moving. Newspaper/magazine/paper works well. A stick could potentially be bad since it would have no give. It's pretty easy to tell if the fan is going to stop or not.
