What is the purpose of adding antifreeze to the water in the radiator of a car?

The purpose of adding antifreeze to the water in a car's radiator is to lower the freezing point of the coolant, preventing it from freezing in cold temperatures. Additionally, antifreeze raises the boiling point, allowing the engine to operate at higher temperatures without overheating. It also provides corrosion protection for the radiator and engine components, ensuring longevity and efficient operation of the cooling system.


What might be the problem if there is ice under the radiator cap and the motor is overheating?

It sounds like the antifreeze / distilled water mixture is freezing because the antifreeze mixture is too weak for the outside temperature Usually the antifreeze and preferably distilled water mixture is 50 / 50 ( Ford states to not exceed 60 % antifreeze )


How does an antifreeze prevent freezing in cold months and overheating and boiling?

It lowers the freezing point and raises the boiling point of water.


How does antifreeze keep the water in your radiator from freezing?

Most antifreeze has a chemical that freezes at a very lower temp than plain water.


Which facts about the use of antifreeze illustrates a rule that governs the physical world?

Antifreeze keeps water from freezing when it is cold out. The antifreeze liquid lowers the freezing point of the water. Even when freezing (to a slurry) it does not form solid ice that can rupture the radiator. The antifreeze combines the water to form a liquid with a lower freezing point than water alone.


Why is ethylene glycol added to water in radiator during summer?

Ethylene glycol is added to water in the radiator during summer to act as an antifreeze and coolant. It helps prevent the water in the radiator from freezing in cold temperatures, while also raising the boiling point of the coolant to prevent overheating in hot weather.


What is a sentence for the word antifreeze?

A sentence for the word antifreeze may be, " What is the best antifreeze to use in drinking water?" Antifreeze is a liquid which is used to lower the freezing point.


Where do you add the antifreeze?

During Winter or whenever it is cold to lower the freezing point of the water in your car radiator. :] F


What is the liquid in the radiator reservoir of a volkswagon jetta 1999 Is it suppose to be water bc mine isn't?

The liquid in the radiator reservoir of a Volkswagen Jetta 1999 should ideally be a mixture of water and antifreeze (coolant). This mixture helps regulate the engine temperature and prevent freezing or overheating. It is important to check and maintain the proper coolant levels to ensure the engine runs smoothly.


What does ethylene glycol do to the solution in a vehicles radiator?

Ethylene glycol mixed up to 50% with water, lowers the freezing point of the mixture, while remaining an excellent heat transfer medium. It protects the engine from either freezing or from overheating.


What is the freezing point of radiator fluid that is 50 percent antifreeze by mass?

I believe a 50 / 50 mixture of antifreeze and water freezes at - 34 degrees Fahrenheit


What can antifreeze do to the boiling point of the water in a car's radiator?

Antifreeze raises the boiling point of water in a car's radiator by reducing the vapor pressure of the coolant mixture. This helps prevent the engine from overheating by allowing the coolant to operate at higher temperatures before boiling.
