I got home from work today and when I turned off my car I could hear this high pitch screeching noise. Like what you hear when your tv is on but muted, but a little louder. I start poking around and it is coming from under my hood! The car is off, the keys are in my pocket, but it’s making a weeeeeeeeeeeeeeeeeee noise. I cant determine where its coming from in the hood, sounds like somewhere from the alternator to the turbo on that side. Any ideas? I don’t see any fluid leaking.. I guess if it does it again tomorrow I will have to bring it in. I parked away from my house in case it bursts into flames tomorrow.
