I posted the link to show you the noise since I can't describe the noise. Happens when the car is running, every 30-45 seconds or so. Also happens after shutting the car off for about 20 minutes after the car is turned off, every 30-45 seconds also.

Hi,

Is this noise happen at the 8 second mark of the video? I can't really hear anything if it happens some other time. The video helps but can you take a video so that we can hear the noise a couple times? Also, pop the hood and take it from under the hood or at least try to locate where it seems to be coming from. Thanks
