RE: 93 300e Weeeeeeeeeerrrrrrrrr in the morning

I have a 93 300e. When I start it in the morning I hear a weeeeeeeeerrrrrrrr coming from the engine. After a few minutes of running it is gone. Does anyone know what this is?

I was told that the Poly Belt needs replacing, could this be the source of the noise? What does it cost to replace a poly belt? also are there any other items I should have replaced (because of duplicative labor) while they are replacing the poly belt?

Thanks
In may be your Air pump. The Air pump cuts in at start up. Its connected to the drive belts by a clutch which could also go bad.

It could also be that your belt tensioner has failed so your belt is loose and squeels on cold start.
