Q:

What are the types of antifreeze?

A:

Quick Answer

The different types of antifreeze include ethylene glycol and propylene glycol, which are prominently used as car engine coolants. Less popular antifreeze agents are methanol and 1, 3 propandiol and glycerol.

Full Answer

Antifreeze retains its liquid form when heated to a point where other liquids boil. As such, it serves as an excellent coolant, because liquids transfer heat away from a solid much better than gases do. Methanol is flammable, and therefore unpopular for use as antifreeze in cars. Ethylene glycol can be used in cars, but is less popular than propylene glycol because of its toxicity to animals. Propylene glycol is much less toxic than the others, although it is subject to biological contamination.

  • Q:

    Is coolant the same as antifreeze?

    A:

    Antifreeze and engine coolant are the same product, sold in the same packaging, and both go into the vehicle's radiator. All gasoline engines need water to circulate through them to maintain a stable operating temperature. Antifreeze keeps the water stable across a broad range of temperatures, from freezing to boiling.

  • Q:

    What does antifreeze smell like?

    A:

    Antifreeze has a sweet smell like pancake or maple syrup. If the smell is noticeable inside the vehicle, the heater core is likely to be leaking. Smelling the sweet scent outside the vehicle indicates that the coolant leak might be in a hose or the radiator.

  • Q:

    What is the difference between antifreeze and coolant?

    A:

    Antifreeze is used to lower a freezing point, whereas coolant is used to remove heat. Antifreeze is chiefly used to lower the freezing point in the radiator of a motor vehicle. Coolant is a substance typically used to reduce the temperature of the liquid in an automobile cooling system.
