Question about 2002 Cadillac Deville
There isn't one !
Notice: Do not add cold water to the cooling system with the engine at or above operating temperature. Adding cold water causes rapid cooling, resulting in possible engine damage.
NOTICE: When adding coolant, it is important that you use GM Goodwrench DEX-COOL® or HAVOLINE® DEX-COOL® coolant. If Coolant other than DEX-COOL® or HAVOLINE® DEX-COOL® is added to the system the engine coolant will require change sooner; at 50 000 km (30,000 mi) or 24 months.
Notice: Do not use a solution stronger than 70 percent antifreeze. Pure antifreeze can freeze at -22°C (-8°F).
Important: This engine is not equipped with block drains, 2.5 L (2 qt) of residual coolant remains in the engine block.
Refill the cooling system. In order to ensure sufficient engine cooling, freezing and corrosion protection, maintain the protection level at -37°C (-34°F) or lower.
Start the engine.
Place the heater and A/C control in any A/C mode except Max and the temperature in the highest setting.
Allow the engine to continue idling until the lower radiator to water pump hose is hot.
Turn OFF the engine.
Allow the engine to cool to outside temperature. Ensure the coolant level in the surge tank is at the proper level (1).

dr_greg is incorect. The bleeder valve is on the thermastat housing near the intake manifold. Follow the hose from the top of the radiator to the the engine. Look for something that looks like a 12mm head nut with a metal nipple comming through it. If you change your coolant but do not open this valve untill coolant flows from it you may cause an air pocket to remain in your engine, possibly causing your car to over heat.

According to my data base it has one, but it doesn't give the location. The ones I've seen are located on the thermostat housing or on the engine close to it and they look like a brake bleeder valve.

Did you replace the thermostat? If not replace it. Is the cooling fan running? If not check the fuse & thermal relay. If it has a bleeder valve it will be located on the highest part of the cooling system. It may not have one. With the engine cold remove the radiator cap. Make sure the radiator is full. Set the heater control to Hot. Start the engine and watch for escaping air bubbles. Keep the radiator full until you see no more air escaping. If it continues to overheat repeat the process.
