Hi, I drove my GN up to sudbury from london today and for about the last 5 minutes, there was a loud knocking noise. I believe I've traced it to the water pulley (it's loose) or fan below it, but I'm not sure. I don't have all of my tools here and can't really order any parts. If anyone can give me some potential solutions, or help me out, it would be greatly appreciated. Thanks.
