Hello!
Looking to tap into the wealth of knowledge here, yet again.
My 2012 has had a distinct whine at low speeds, actually it's more of a whistle. It may be present at high speed, but it is drowned out by all the other noise. It's been about the exact same for a year or two. It doesn't appear to be influenced by the outdoor temp, or the temp under the hood. It also happens whether I'm in park or driving. At idle you won't hear it, but around 1000-1300 RPM it appears. Like you're crawling through your neighborhood looking for your dog at night.
I've looked into this before, and usually people suggest the timing chain wear as the cause. In my case, it does not sound like that. For my own special noise, it's much smoother sounding than the chain tensioner issue. It's also higher pitched, not 'gritty' at all in nature - like a smooth whistling noise. This is the kind of noise where I'll ask my girlfriend "do you hear that?" and she looks at me like I'm crazy, but it actually drives me nuts.
Any likely culprits that I should investigate first to rule out? My serpentine belt is quite new and the noise was present before the belt change. I was thinking maybe the alternator? Maybe a vacuum issue somewhere? I plan on having someone sit in the driver seat to give her a mild rev while I am underneath to try and pinpoint better.
I totally get that asking for help on a random noise is a lost cause, but I figured it was worth a shot in case this is a known thing that folks have dealt with and may have some starting point suggestions for me.
Thanks.
