Unusual noise only when hot
Car has all new OEM belts, pulleys, ati harmonic, and alternator. I just replaced the alternator again thinking that was the cause, but unfortunately not. Water pump fairly new.
I’ve sprayed the pulled and belts with water to try and get a pitch change but no luck.
Seems to be coming from the drivers side of the engine compartment but can’t be positive.
Has anyone ever heard something like this?
thanks!

https://youtube.com/shorts/vFTQIF3uWHU?feature=shareRecently got this noise but only when the motor is hot. In the video you can hear the high pitched noise cut in and out then stay constant. (To me it sounds more like white noise, speaker static, feedback, high pitch, which is unusual. Not your typical belt or pulley squeak.)

If that is a bearing going bad, this would be the first for me in 40yr of changes bad bearing having that pitch sound.I,been thinkingg and ia knoww the bearing r sealed but try some wd or what ever u have. Im just trying to give u some wierd advicee and one of them might work.
grammer and sphell check is all over the place so if u can read let me know because evey time i fix it another freaks out anyway.Just listened to it a few time. It might be a vaccum leak by the TB it got louder wen u got close to it. So i wood get 2 gallons of gas and prou it all on the TB and if it revs up u found ur problem but u might make another problem with a fire.
Of starter , brakee or what ever is flamableLast edited by helga203; Apr 26, 2022 at 11:24 AM.
