It sounds like a pulley but if you have an auto it may be your fan clutch too. If you have not done your idler pulley, tensioner pulley, belts yet you are probably overdue. bad pulleys tend to have a kind of chirp to them and fan clutches tend to have kind of an off balance rotational sound

I have not yet done the pulleys or belt. while car is running nothing looks loose or out of the ordinary. When the car was off i spun the fan to see if it was really loose but it seems pretty stiff i would imagen the fan would have a lot of play it the clutch was going ?

Bottom line is you are going to have to do a physical inspection first. There is no way around this. Spin the pulleys by hand. They should not make noise or spin freely like a caster wheel. It should have some resistance. Inspect your belt for cracks and wear. DIYs are on this site.
