    My belt tensioner pulley is squealing like heck.I shot a little w d 40 on it and the noise went away for about 5 min.Now I am on the web. investigating how to replace it my self.I see on my 3.8 supercharged engine there are two belts.The main belt on the alt. side is the one that needs replacing.Get or draw a diagram of the belt routing.Disconnect battery terminals? Its very important I am no pro... and I haven't done this on this car before.But looking at It .It looks like I need to remove the coolant resv.To start to get at the tensioner.Then use a 15 mm socket or wrench to loosen the belt. Maybe the alt. might need to be removed.That's about where I'm at.Wish me luck.I've hear its tough .
