Video of cold idle engine intermittent squeal (how to determine cause)?
Attached is a video of my cold idle engine intermittent squeal.
Debugging hints to isolate the cause are welcome.
I replaced the power steering reservoir fluid twice with a quart of Dexron VI which seemed to help a little - but it still came back (the power steering fluid container is empty so you see the white bottom; all the ATF sucked out twice filled the S. Pellegrino water bottle).
Caveat: This is my first video upload ever so I may screw it up.
