How to replace the air conditioning drive belt on Chevrolet Silverado 3500 Classic?

Start the air conditioning Drive Belt replacement by taking away the accessory Drive Belt then by securely raising the vehicle. The installation procedure requires removal of the engine shield bolts followed by removal of the engine shield itself. Utilize a ratchet tool inside the opening of the a/c belt tensioner adapter to turn the tensioner clockwise thus eliminating belt tension before extracting the a/c belt from the pulleys.
