Hello there, many different faults can cause your 2001 Cadillac DeVille to overheat. If the car overheats when at idle, then the most likely faults would be the cooling fan, thermostat, air in the cooling system, or a clogged coolant passage. This vehicle should not be driven until the overheating problem is resolved as repeated overheating can cause damage to the engine. A qualified technician, such as one from YourMechanic, will be able to diagnose the overheating problems and perform any repairs required.
