Loud squealing noise

Hello,

The pulleys on the front of your engine are basically round wheels that hold belts in place and act as pivot points for the belt. Some are stationary and do nothing but provide a pivot point, while some have a shaft attached them and work a component, like a water pump, or alternator, or power steering pump, etc. No matter what they do they all have a bearing in them. These bearings have an inner and an outer race with ball bearing in them and the races are precision ground. If the lubrication wears out then the ball bearings will wear out the races making slop in them and causing bearing failure. As the bearing fails it will produce a squealing noise.
To test a bearing grab a hold of the pulley and look for any play at all. If any play is present, the bearing is no good and must be replaced. I have included a link for you to go to down below:

Hello again,

It should have a little tension to it because it is attached to the shaft and the shaft is attached to the pump and the pump will always have fluid around it causing a little tension, but not too much.
