How to replace the drive belt on 2003 Cadillac DeVille?

The first step to replace the Drive Belt involves eliminating the auxiliary Drive Belt from the system. Dehydrate the Power Steering Pump Drive Belt by using half-inch drive extension to release tension on the belt drive tensioner before taking off the Drive Belt from the Power Steering Pump and return the tensioner to its initial state. The installation of the Drive Belt requires manual passage through all pulleys except for the Power Steering Pump and the Drive Belt tensioner . A 1/2 inch drive extension should be used to compress the tensioner so you can pass the belt through its wheel. Complete belt routing under tension and check that each pulley contains its proper position before slowly returning the tensioner to its original spot for belt tensioning. Examine the belt for correct positioning following installation while restoring auxiliary drive belts if present before engine start-up for proper belt operation test.
