So I have a not so slight whistle under my hood
car runs perfectly
except for this annoying ringin
Initially I thought it was a pulley or a bearing
went to a mechanic and changed bearing
got the altenator check and thats perfect
im lost for ideas wondering if anyone on here can help me or have encountered a problem like this


here is the video

Could be the tensioner bearing but I'm curious to hear it with the A/c on and then again off. It sort of sounds like the A/C compressor pulley too.

[BahamaMack]

Its whistles when the ac is on and off

Boy, that would really grind my gears! If I may ask, which bearing did your mechanic replace? Those 2 idler pulleys might be the cause. Although I've experienced a bad A/C compressor and it's a raspy sound even when you turn the A/C off. Just to be sure you could remove the A/C belt and see if the noise stops. That's where my money is

[BahamaMack]

Removed the belt and the noised stopped
so im figuring now its one of my idler pulleys

[BahamaMack]

Update!!
Changed belts and tensioner pulleys
noise is still there!!! Urgh!!!!
any help?!?!?!!

[paranoidjack]

Well, what belt did you remove to make the noise stop? It is something else on that belt, other than what you just changed...

[BahamaMack]

Just the belt and my tensioner pulleys
my nex move if looking at the power steering pump and the water pump....

[BahamaMack]

Once the belt around the altenator is removed the noise stops
