How to replace the accessory drive belt on 2008 Chevrolet Express 3500?

First step for replacing the accessory Drive Belt involves removal of the air cleaner assembly. The next step requires removing the retaining bolt of the coolant recovery reservoir and placing the reservoir to the side. The replacement process requires users to attach the breaker bar with hex-head socket to the Drive Belt tensioner bolt then turn it clockwise to decrease belt tension. First remove the Drive Belt from its placement on the pulleys and from the Drive Belt tensioner. Then use a deliberate approach to reduce the Drive Belt tensioner tension. Clean all pulleys thoroughly before evaluating their belt surfaces when the tensioner bolt breaker bar with socket is detached. When putting the Drive Belt into position start by placing it around all pulleys but the idler pulley. Next use the breaker bar with hex-head socket to loosen the belt tensioner bolt through clockwise rotation. You need to install the Drive Belt below the idler pulley then slowly decrease the belt tensioner pressure through the breaker bar and hex-head socket. Before you position the coolant recovery reservoir you need to inspect and verify proper installation and alignment of the Drive Belt then install the retaining bolt and tighten it to 11 n.m (97 lb in). To complete the task reinstall the air cleaner assembly.
