The coolant level sensor, (module) on them will do that. You will want to do the test with the engine warmed up to be sure.
DESCRIPTION This lamp will be illuminated when engine coolant level in the radiator drops below a predetermined level. To turn lamp off, check cooling system, then add coolant to bring system to proper level. OPERATION Some vehicles use a buzzer or indicator lamp to convey a low coolant level condition. The buzzer or lamp is activated by a sensor, located in the radiator, when the coolant level becomes one quart low, or more.
