How to replace the Air Conditioning (A/C) drive belt on 2004 Chevrolet Express 1500?

Begin by taking out the accessory Drive Belt followed by lifting the vehicle before changing the air conditioning (A/C) Drive Belt. To relieve the belt tension apply a ratchet in the tensioner opening and rotate the tensioner clockwise before pulling off the a/c belt from the pulleys. After you have gradually let go of the tension on the a/c belt tensioner remove the ratchet. The first step entails inspection of pulley belt surfaces followed by new a/c belt installation which should proceed around the crankshaft balancer. The ratchet used in the opening of the a/c Drive Belt tensioner adapter should turn the tensioner clockwise first to reduce belt tension before installing the a/c belt across the idler pulley and a/c compressor pulley. Examine the a/c belt after you have removed the ratchet from the a/c belt tensioner while releasing its tension for correct position and proper belt alignment. To complete the task lower the vehicle after fitting the accessory Drive Belt.
