One way people know that the car is burning coolant is by the sweet and sticky smell of antifreeze
Antifreeze
An antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes increase the boiling point of the liquid, allowing higher coolant temperature.

What can cause a car to burn coolant?
Coolant comes in contact with the gasket separating the cylinder head from the bottom end of the engine. If this gasket starts leaking, coolant can escape the system and enter the combustion chamber of the cylinders, or leak out to the outside of the engine block. A head gasket leak is a serious issue.
What happens when you burn coolant?
