Could be some overheating problem there; on 4.5L and 4.9L engines, check this procedure:
* Drain the coolant to a level below the thermostat housing.
* It may be necessary to remove the upper air filter assembly on some models.
* Remove the 2 bolts securing the upper thermostat housing to the lower housing.
* Remove the upper thermostat housing.
* Remove the thermostat and O-ring from the lower housing.

My retired uncle has a 97 cadillac deville sts that runs well but after a short distance or time idling begins to overheat. He has replaced the water pump, thermostat and had the radiator and head gasket checked. Unfortunately he lives in a rural area and there is no local cadillac dealership for diagnostic repairs.
