Hi guys, I've been trying to track down and find out more info about this to no avail.

See video below for exact sound it's making. I saw on a few threads it mentioned a wategate but nothing specific. Has anyone else seen or dealt with this before? Mine just started this week, it doesn't happen every time I shut it down and it doesn't seem like I have any loss of boost when driving.


Thanks!

Does the noise happen any other time? If so, does the noise sound any different during those times?

 

No, it only happens when I shut it off. It seems fine on my trip to work (20 min)when I turn it off, no noise. After the trip back home it will make the noise but usually a shorter duration than the video. Maybe only the grind for less than a second.

The first time it happened was after a drive that was about 45 min and was nearly identical to the video.

 

I'm at a bit of a loss here. Have you checked to see if the sound is coming from one of the items that's connected to the serpentine belt? That or maybe from the radiator fan?
