How to replace the drive belt on 2004 Cadillac DeVille?

Start replacement of the Drive Belt by taking off any auxiliary Drive Belt that is present. A 1/2 in. Drive extension should be used to alleviate tension from the belt drive tensioner allowing you to take the Drive Belt from the Power Steering Pump before slowly resetting the tensioner to its original position for belt removal. When installing drive the new belt proceed by threading it only through the pulleys that are not the Power Steering Pump and the Drive Belt tensioner. When running the belt around the tensioner wheel use a 1/2 in. Drive extension to apply pressure on the tensioner. During tension application replace the belt through all pulleys so it fits correctly before loosening the tensioner to the start position for applying Drive Belt tension. After completion of belt installation check the route and position of belt alignment and re-install auxiliary belts if they are present before starting the engine for belt and accessory functionality validation.
