98 Saab whining sound, idler pulley. Video 1

My saab 2.0 turbo had this whining sound that I was told by the seller was the turbo. I called BS, bought it for a good price. After looking all over internet to find a simlilar problem, I figured out it was the idler pulley.
I wish someone post a video a month ago. So here you go. 4 minite fix. See vid 2 for how to loosen belt.
