Engine noise
I have an intermittent sound coming from my engine. It shows up out of nowhere and could last 20 seconds to 2 minutes. Because it's intermittent, I can't seem to pinpoint where it's coming from. Sound file is attached. Hopefully, one of you can recognize it and help me.
It's a 2008 with 79K miles.
Thank you

No codes and it drives fine. Water pump was replaced 3 years ago. Didn't think it would go bad this fast. Right now I'm leaning towards the alternator starting to go bad, but will keep an eye on it. This noise being intermittent makes it very difficult to troubleshoot. Thanks for your suggestions.

I know I am going to get some negative responded to this, but whatever. If you think it's the alternator, have you tried knocking on it with a hammer or heavy wrench. Usually when those go bad, it's the brushes or internal contacts and the vibration of hitting it will cause a change either for the good or bad. Just a crazy low tech test you can try. Years ago I used to always have over powered stereos that would stress the alternator and would frequently has to replace them. Sometime this trick would work.
