Water is used as coolant in car radiators because it has high specific heat capacity of 4200 Joules. It has the highest specific heat capacity than any
other substance. That is why it is used as coolant in car radiators
Water isn't used in car radiators, radiator fluid is. that is used because it is a liquid of the right density to hold radiated heat from the radiator and pass it around the car where it is needed.
So that the water used as coolant in most car radiators does not freeze overnight. If it does then, because ice expands as it freezes and melts, it can crack the engine block. The antifreeze lowers the freezing point of the coolant and reduces the risk. The more antifreeze, the less risk of freezing. But too much and it will boil when the car is running. Additives in antifreeze also reduces corrosion and raises the boiling point.
Most car radiators are made of aluminum or a combination of aluminum and plastic, which are not susceptible to rusting like iron or steel. Additionally, the cooling system in cars is filled with coolant that contains corrosion inhibitors to protect the radiator and other components from rusting. Regular maintenance, such as flushing and replacing the coolant, also helps prevent rusting.
Yes. The antifreeze/coolant also raises the boiling point and has lubricant and anti corrosive properties.
Water alone is not recommended. It should be mixed 50/50 % (minimum) with antifreeze. This mixture helps transfer heat, keeps corrosion under control, lubricates water pump and keeps the coolant from freezing in cold climates.
Clean water should be used and mixed with the proper coolant for your car.
Almost all car manufacturers have used cast iron radiators at one time or another, however most are now made of an aluminum alloy that can cool the water intake quickly.
.
Distilled water IS good for radiators. In fact, manufacturers recommend using nothing but distilled water to mix with antifreeze. Tap water contains minerals, which can promote corrosion. So tap water should be used in a cooling system only in case of an emergency.
No, it is not recommended to put salt water in a car radiator as it can lead to corrosion and damage to the radiator, water pump, and other components of the cooling system. It is best to use a coolant mixture of water and antifreeze specifically designed for car radiators.
You mix it with water.
Coolant usage depend on the usage of the car and on the weather conditions .coolant can be stored and used till 20000 km. And can be further used by adding water till it becomes fade.
