Answers :

IT,S YOUR PULLEY THATS BAD
The ac not being on does not mean it is not the cuase of the noise. The bearing may be going bad on the ac. You may want to take a look at the idoler pulley as well. They are the same as the tensioner aside from the fact it is hard mounted. Try spraying a lubricant on the idoler and if that does not help spray the ac at the cak of the pulley. Which ever ones helps will let you know which is the cause.
