changing serpentine belt and pulley 90' sedan deville
Use a socket and ratchet and place on the 95 Deville's belt tensioner pulley. Pull to the side to release tension on the belt. Remove the belt and replace it, then lower the pulley back into place.
Same exact thing happened to my '96 cadillac deville just last week. The belt actually shredded. If you look at the location of the belt (right at the lower right corner of the engine) you may decide you may not want to mess with it yourself. I didn't. I took it in to Firestone and they fixed it parts/labor for $60
loosen the tensioner bracket, remove old belt. replace with new belt. tighten with tensioner. job complete!

It sounds like you have a bad water pump. It had seized up on you and has burned the belt.
The cam on this engine is driven by a CHAIN and not a belt. Therefore, It has no timing belt.

To change the water pump on a 2001 Cadillac DeVille, first ensure the engine is cool, then disconnect the negative battery cable. Remove the serpentine belt and drain the cooling system. Next, detach any components obstructing access to the water pump, such as the alternator or bracket, and unbolt the pump from the engine block. Install the new pump with a new gasket, reassemble the components, refill the cooling system, and reconnect the battery.
