How to replace the accessory drive belt on GMC Sierra 3500 Classic?

The first step to change the accessory Drive Belt starts with opening the hood to remove the air cleaner outlet duct. A hex-head breaker bar with socket should be used to twist the Drive Belt tensioner in a clockwise direction until the belt tension releases. Then pull the Drive Belt off the pulleys and tensioner. Complete the replacement of the Drive Belt tensioner by moving the socket and breaker bar away. Clean each pulley belt surface before the new Drive Belt installation that involves bypassing the idler pulley. The hex-head socket attaches to the breaker bar that guides the installation of the belt tensioner bolt clockwise until tension fades, and the Drive Belt moves under the idler pulley. Complete the tension relief on the belt tensioner before removing the breaker bar along with its socket. Check the Drive Belt alignment and reinstall the outlet duct of the air cleaner then start the vehicle for Drive Belt operation verification before hoisting the hood.
