The wife's rig started making some pretty odd noises last week when it got really cold. At first it wasn't much, then on a few occasions (like today) it got really bad. It sounded like the belt chirping or a bad pulley bearing. There's a lot going on up front and its hard to isolate it. However, after running my stethoscope around I feel like I pegged it down to the tensioner area. When I started playing around with it I noticed the little washer on the front felt loose. Turns out the bolt was a bit loose as well. I tightened everything up and it seems to have fixed it for now. I'm wondering if anyone else has had issues with this. If I hear it again it might just get a new tensioner.
