There is a coolant leak.
Hello! The easiest way to locate a coolant leak is to have the cooling system pressure tested, which can be performed when the engine is cold. The failed component would most likely be the coolant pump; it’s usually good practice to change out the thermostat at the same time. Once the repair is verified by pressure testing the system again, coolant can be added, and the cooling system can be bled. You may need the aid of mechanic to pressure test the cooling system, and the car may have to be jacked-up to inspect the underside for the leak. I would recommend having this coolant leak inspected and serviced by a certified mechanic.
