Hello!

I have had a whirring sound coming from the front of my Endeavor for over a year now. It commences upon starting my car - not when I've been driving it for a while. I tend to think it is a pulley causing the sound.

I am in the process of trying to figure out where the belt tensioner is. How do you loosen the belt? On other cars I usually just loosen the alternator and that would allow me to adjust the serp belt, however, on the Endeavor the guide pulley in the center has a bolt underneath it which I removed, and nothing happened. I can't find a nut or bolt that will loosen the belt. :unsure:
