I am having this high pitch squeal sound that just started on the car. I was thinking the belt at first, though I replaced it very recently. Interestingly though it seems to disappear when I make a hard turn left but otherwise comes back, even when the car is stopped. Any ideas on what I can check out to see what it is?

 

I wouldn't rule out the serpentine belt area yet, could be the belt tensioner or any of the pulleys. Going off what you would say I would check the power steering fluid level to make sure that is alright. Don't want to have a problem with that.

 

One way to tell for sure is remove the serpentine belt and start the engine (run it only for a short time without the belt though)

 

Does the noise stop when you stop the car at a stop sign?
