How to replace the drive belt for 4.8L, 5.3L, and 6.0L engines on Chevrolet Silverado 3500 Classic?

The Drive Belt replacement procedure for 4.8l, 5.3l and 6.0l engines starts by loosening the air cleaner outlet duct clamps which secure the Throttle Body and mass airflow (MAF) / intake air temperature (IAT) sensor. After disconnection of the radiator inlet hose clip from the outlet duct, remove the air cleaner outlet duct. A hex-head socket breaker bar can be used to turn the Drive Belt tensioner bolt clockwise which reduces belt tension before removing the belt from the pulleys and the Drive Belt tensioner while also easing tension when done. Before placing the new Drive Belt onto the system, clean and check the surfaces of all pulleys while routing the belt around all pulleys excluding the idler type. After installing the hex-head socket on the belt tensioner bolt with a breaker bar proceed with clockwise rotation to decrease tension while positioning the Drive Belt beneath the idler pulley before you unwind the tension. Inspection of the Drive Belt should confirm its proper alignment and installation before placing the arrow at the Throttle Body end of the duct in line with the Throttle Body stud for duct reinstallation. The next step includes attaching the radiator inlet hose clip to the outlet duct and tightening air cleaner outlet duct clamps at the Throttle Body and the maf/iat sensor to 4nm (35 inch lbs.).
