Propylene Glycol, on the other hand, is a less toxic and safer alternative. It also has good heat transfer properties, but it has a lower boiling point than Ethylene Glycol.

Most of these will cause puddles of liquid under the car unless the leak is minor. Another possibility is an internal leak, such as a blown head gasket, where the coolant gets into those engine components it should not. The most common failure that causes this is a broken head gasket, allowing coolant to enter the combustion chamber. So why is coolant important? Coolant is necessary for transferring the heat of the engine in a safe way. It prevents engine damage by limiting the range of temperatures an engine has to endure.
