How to replace the drive belt on 2004 Cadillac CTS?

Directional movement of the Drive Belt tensioner towards the clockwise position creates mounting space for removing the Drive Belt from the Water Pump pulley. Narrow the tensioner to relax its position as the Drive Belt is carefully extracted from the accessory drive pulleys. Use the Drive Belt routing diagram to guide the Drive Belt installation during which the Drive Belt tensioner needs clockwise rotation when accessing the accessory drive pulleys but avoid the Water Pump pulley. You should position the Drive Belt above the Water Pump after proper alignment into the accessory drive pulley grooves. Before leaving the area, check that the Drive Belt correctly positions within all accessory drive pulleys.
