idler pulley replacement on 1991 GMC Vandura 2500

Does the bolt on the idler pulley need to be turned clockwise to take it off instead of the usual way? Because the bolt on mine is hard to get off and i want to make sure im turning it the right way.

This is the best to go to really find out the factory method.
