Is Antifreeze And Coolant The Same Thing?
When it comes to car maintenance, one of the most important things you can do is keep your engine cool.
This is why it’s so important to use the right type of coolant and antifreeze in your vehicle.
But is antifreeze and coolant the same thing?
Many people are not aware of whether they are the same or not.
We will discuss the answer to this question and some of the differences between them.
Is Antifreeze And Coolant The Same Thing?
The answer is no, they are not the same thing.
Coolant is a mixture of water and glycol or glycerin.
This mixture is used to transfer heat away from engine parts.
It does this by circulating through the engine and absorbing heat, car gauge temperature goes up.
The cooled coolant is then sent back through the engine to absorb more heat.
Antifreeze is a solution of water and ethylene glycol or propylene glycol.
This solution is used to lower the freezing point of water, which prevents the coolant from freezing in cold weather.
Antifreeze also raises the boiling point of the coolant, which prevents it from overheating in hot weather.
So, as you can see, coolant and antifreeze serve different purposes.
Coolant is used to transfer heat away from engine parts, while antifreeze is used to prevent the coolant from freezing or boiling.
10 Major Differences Between Antifreeze & Coolant
While they are not the same thing, there are some similarities between antifreeze and coolant.
Here are some of the major differences between them:
1. The State Of Matter
Coolant is in a liquid state, while antifreeze is in a solution state.
This means that coolant is made up of molecules that are not bonded together, while antifreeze is made up of molecules that are bonded together.
2. Application
Coolant is used in car radiators to transfer heat away from engine parts, while antifreeze is used in the cooling system to prevent the coolant from freezing or boiling.
3. Desirable Traits
The desirable traits of coolant are that it is a good heat conductor and has a low freezing point.
The desirable traits of antifreeze are that it has a high boiling point and is non-toxic.
4. Chemical Composition
Coolant is made up of water and glycol or glycerin, while antifreeze is made up of water and ethylene glycol or propylene glycol.
Glycol is a type of alcohol that is used in coolants to prevent corrosion, while ethylene glycol and propylene glycol are types of glycol that are used in antifreeze to lower the freezing point of water.
5. Freezing Point
The freezing point of the coolant is -37°C, while the freezing point of antifreeze is -60°C.
This means that antifreeze can prevent the coolant from freezing in much colder weather than coolant can.
Propylene glycol is used in antifreeze to lower the freezing point of water, while ethylene glycol is used to raise the boiling point of water.
6. Boiling Point
The boiling point of the coolant is 100°C, while the boiling point of antifreeze is 140°C.
This means that antifreeze can prevent the coolant from boiling in much hotter weather than coolant can.
That causes car overheating and then going back to normal.
Ethylene glycol is used in antifreeze to raise the boiling point of water, while propylene glycol is used to lower the freezing point of water.
7. Viscosity
The viscosity of the coolant is lower than the viscosity of antifreeze.
This means that coolant can flow more easily than antifreeze.
Glycerin is used in coolants to reduce the viscosity, while ethylene glycol and propylene glycol are used in antifreeze to increase the viscosity.
The increased viscosity of antifreeze helps it to transfer heat better than coolant.
The increased viscosity of antifreeze also makes it more resistant to freezing than coolant.
However, the increased viscosity of antifreeze can make it more difficult to flow through the radiator.
8. Conductivity
The conductivity of the coolant is lower than the conductivity of antifreeze.
This means that coolant can transfer heat better than antifreeze.
Water is a good conductor of heat, while ethylene glycol and propylene glycol are poor conductors of heat.
The increased conductivity of coolant helps it to transfer heat away from engine parts better than antifreeze.
However, the increased conductivity of coolant also makes it more likely to freeze than antifreeze.
Glycol is used in coolants to reduce the conductivity, while ethylene glycol and propylene glycol are used in antifreeze to increase the conductivity.
The increased conductivity of antifreeze helps it to transfer heat better than coolant.
9. Corrosion Inhibitors
The corrosion inhibitors in the coolant are designed to protect metal surfaces from corrosion.
The corrosion inhibitors in antifreeze are designed to protect engine parts from corrosion.
Glycol is used in coolants to prevent corrosion, while ethylene glycol and propylene glycol are used in antifreeze to prevent corrosion.
The increased concentration of corrosion inhibitors in antifreeze helps it to protect engine parts from corrosion better than coolant.
However, the increased concentration of corrosion inhibitors in antifreeze can also make it more toxic than coolant.
Propylene glycol is used in antifreeze to reduce toxicity, while ethylene glycol is used to increase the boiling point.
10. Cost
The cost of coolant is lower than the cost of antifreeze.
This is because coolant is made up mostly of water, while antifreeze is made up of water and glycol or glycerin.
The increased cost of antifreeze is due to the added ingredients that are used to lower the freezing point, raise the boiling point, increase the viscosity, and increase the conductivity.
The increased cost of antifreeze is also due to the added corrosion inhibitors.
Ethylene glycol is used in antifreeze to lower the cost, while propylene glycol is used in antifreeze to increase the boiling point.
Why Is Antifreeze Mixed With Water?
The main reason that antifreeze is mixed with water is to lower the freezing point of the water.
Water has a very high freezing point, while ethylene glycol and propylene glycol have very low freezing points.
When water is mixed with antifreeze, the resulting mixture has a lower freezing point than water.
The lower freezing point of the mixture helps to prevent the engine from freezing in cold weather.
The mixture also has a higher boiling point than water.
When the engine is operating at high temperatures, the mixture can prevent the coolant from boiling.
The boiling point of the mixture is also raised when glycerin is added to the mixture.
Glycerin is a thick liquid that is used to increase the viscosity of the mixture.
The increased viscosity helps the mixture to transfer heat better than water.
The addition of glycerin also lowers the conductivity of the mixture.
Antifreeze Vs Water: All The Differences
When it comes to your car, you need to make sure that you are using the right fluids.
One of the most important fluids is the coolant.
The coolant is responsible for keeping your engine cool.
In the early times, the water acted as a coolant.
However, now most people prefer professional antifreeze over water.
Take a look at the differences between antifreeze and water.

Glycol is a poisonous substance that can cause kidney damage.
Glycerin is also a poisonous substance that can cause liver damage.
The increased concentration of these substances in antifreeze can make it more toxic than water.
Propylene glycol is used in antifreeze to reduce toxicity, while ethylene glycol is used to increase the boiling point.
2. Freezing Point
The freezing point of water is very high, while the freezing point of antifreeze is very low.
When water is mixed with antifreeze, the resulting mixture has a lower freezing point than water.
The lower freezing point of the mixture helps to prevent the engine from freezing in cold weather.
The mixture also has a higher boiling point than water.
When the engine is operating at high temperatures, the mixture can prevent the coolant from boiling.
The boiling point of the mixture is also raised when glycerin is added to the mixture.
Glycerin is a thick liquid that is used to increase the viscosity of the mixture.
The increased viscosity helps the mixture to transfer heat better than water.
The addition of glycerin also lowers the conductivity of the mixture.
3. Cost
The cost of coolant is lower than the cost of antifreeze.
This is because coolant is made up mostly of water, while antifreeze is made up of water and glycol or glycerin.
The increased cost of antifreeze is due to the added ingredients that are used to lower the freezing point, raise the boiling point, increase the viscosity, and increase the conductivity.
The increased cost of antifreeze is also due to the added corrosion inhibitors.
Ethylene glycol is used in antifreeze to lower the cost, while propylene glycol is used in antifreeze to increase the boiling point.
