The Coolant Level Sensor on a 2002 Cadillac Deville is typically located in the coolant reservoir tank. This sensor is designed to monitor the coolant level in the reservoir and send a signal to the vehicle's computer system if the coolant level drops below a certain point. It is crucial for the proper functioning of the vehicle's cooling system and to prevent overheating. Regular maintenance and inspection of the coolant level sensor can help ensure the vehicle's optimal performance.
