My tensioner pulley is making all kinds of rattling and metallic clicking noises and I am pretty certain it is dieing. I've never changed one of these before, how do you release the tensioner arm? Is a special tool needed? Once the tensioner arm is loose do you just unbolt the pulley, and are either of these reverse thread?

Thanks in advance for any help with this
