what's causing this noise?
Living in North Carolina, there are no shortages of hot days. When it's hot, over 85, and I drive anywhere, when I go to leave, the car makes this high pitched squealing noise. The noise doesn't last long, and if I rev the car up it goes away pretty quick. I thought it might be the oil filter but after the last service, the noise is still present. Any suggestions or has anyone else experienced this before? Unfortunately, I cannot get the video to load to give an example.

We need a little more info. Please try describing the sound in more detail. What you are doing when it happens. Is it reproducible? Any changes to car recently? Maybe you could try uploading video to YouTube or another site and post the link here.

High pitched squealing, then goes away when revved. Sounds like either a worn or loose belt. Check the belt tension and wear. When replacing a belt, be sure to replace the tensioner as well.
