On the North Star engine you need to remove the air filter assembly and look on the right side of the engine you will notice the thermostat housing connected to the water pump cover on the engine. Once the water pump cover is removed a special socket is needed to remove the water pump. It is also a good idea or install a new belt on the water pump as well.
where is water pump located
Front of engine---r/s underhood
The water pump on a Cadillac DeVille is typically located at the front of the engine, near the center. It is driven by the engine's serpentine belt and is usually mounted on the engine block. Accessing it may require removing various components, such as the belt and sometimes the radiator fan, depending on the engine model and year. Always consult the vehicle's service manual for specific instructions and diagrams for your particular model.

On a 4.9L follow the upper radiator back to the engine. This should be the thermostat housing. The thermostat should be inside. On a 4.6L the thermostate is in the housing which is near the water pump drivebelts "on the coolant crossover housing". If this is not clean I recommend you buy the Haynes for your DeVille.
