Does the freon from the radiator have anything to do with the coolant?

When discussing the use of freon (or chlorofluorocarbon as it is known) it usually refers to refrigeration and air conditioning. When talking about cars, freon gas is used in the Air conditioning unit. It it sometimes used by racing cars in the radiator in leu of regular coolant (or anti-freeze) but this is not a common practice. On regular cars, coolant is an oil based product placed in the cars radiator and reservoir diluted with water. It's function is to allow the radiator fluid (coolant and water), to be heated and cooled beyond the natural point of water to aid in the cooling of the cars engine.


Do you check the radiator liquid when the cars on?

NO! That would be dangerous. Cars' coolant systems are pressurized, so if you open the radiator cap while the engine is running, it will spray HOT radiator fluid (water mixed with ethylene glycol, usually) all over you, and sometimes drain the radiator of coolant.

Why is it too hot in car radiator?

The most common reason for overheating of a car radiator is that there is not enough water in the radiator. Radiators can lose water in a variety of ways, and often need to be refilled. The other possibility is that the water is not being circulated properly. I should add that cars do heat up quite a bit in the sunlight on a hot day, which adds significantly to the chances of overheating the radiator.
