You have a tensioner use a tool like the link below.
http://www.autopart.com/tools/toolsmain/tool/T_2700.htm Use search A785 is a cheaper set. The idler pulley is spring loaded you search for it first. Use a flashlight and find out the adapter needed. Set up the tool and move the idler arm and remove the belt. A lot of belts have a diagram on the box or look on the vehicle for a diagram. Auto Zone or Advanced may loan tools. Spin all idler pulleys any that make noise replace with new ones. These are usually available at the parts store.
