What is coolant and is it the same as antifreeze?
Coolant is the fluid that circulates through passages in the engine block to regulate heat. Many people wrongly refer to it as antifreeze. They are not the same thing, as you have to mix water and antifreeze to make coolant. The mixture makes water an efficient cooler, capable of absorbing and dissipating heat.
Is antifreeze and coolant the same thing?
Though coolant and antifreeze are often used interchangeably, they aren’t the same. Antifreeze is made of ethylene glycol or propylene glycol and is the basic ingredient, but it has to be mixed with water to create coolant, which is the cocktail you will find in the cooling systems of all “water-cooled” vehicles.

How long does coolant last in storage?
The chemical ingredients in antifreeze/coolant are quite stable and virtually never degrade. This means that the commercial product you've purchased can really sit your shelf almost indefinitely without ever going bad—provided, of course, that you keep the container sealed against dirt and other contaminants.
Is antifreeze and coolant the same?
Engine coolant, also known as antifreeze, is mixed with water to keep the radiator from freezing in extreme cold and overheating in extreme heat. There are many different types of coolant, so it's important to know what variety is right for your car or truck.
Can I put antifreeze in my engine coolant?
Once mixed with water, you simply pour antifreeze into the same place as the engine coolant: the expansion tank, or reservoir. It will then filter 'round the engine and mix with your coolant to make sure the liquid does not freeze.
Does my car need coolant or antifreeze?
Along with fuel and oil, antifreeze is essential to a properly functioning engine. Without it, the heat from combustion would cause the engine to rapidly overheat, or even completely seize up.
Does it matter what coolant you put in your car?
Well, you use the coolant that is specified in your owner's manual. If you just need to top it up, the recommendation is still the same, however it is unlikely to cause any serious problems if you add a litre of a different type of coolant, as long as you follow the manufacturer's maintenance schedule.
Can I just add coolant to my car without flushing?
There is no problem with just topping up the coolant. You can add the coolant without flushing out the old. However, with time, the older coolant becomes acidic. This can cause corrosion, and afterward, can cause defects in the cooling system.
Should I let my car run after adding coolant?
Yes, run the engine After you do any work involved with draining the coolant you will either have an exact process to remove air from the cooling system or you will simply run the engine. If you don't the gasses (air) will expand at a greater rate than liquid when the engine get's hot.
Can I drive my car with low coolant?
If your car has a low coolant you can drive for some time. It really relies on the level of coolant. If it is low but it is above the minimum, you can drive your car for a few days. But if it is below the minimum, please do not even try to run your engine.
What are the signs of low coolant?
What are The Warning Signs of Low Car Coolant?Rising Temperature Gauge Inclining Towards Red. After driving your car for some time, you become familiar with the position of your temperature gauge when everything's okay. ... Heater Not Working or Supplying Hot Air. ... Poor Fuel Economy. ... A Sweet Smell.
What happens if I put coolant in my radiator?
The radiator reservoir needs to reach the maximum line because it is where the new coolant is poured into the cooling system. The radiator reservoir stores the excess coolant until it is needed to reduce the temperature of the engine. If the coolant in the radiator reservoir is low, it can cause the engine to overheat.
Does the color of antifreeze matter?
The truth is, color is not a reliable predictor for what type of coolant you have.
How long can an engine run without coolant?
However, if you absolutely must start your car without coolant, it can probably run for about a minute without too much risk of damage. You may be able to get away with as much as 5 minutes of running without coolant, depending on the engine, car model, and how hard you're asking the engine to work.
What do the different colors of antifreeze mean?
The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup.
What happens if you use 100 percent antifreeze?
Filling a Cooling System With Pure Antifreeze Can Also Damage the Engine. Not only does pure antifreeze have a higher freezing temperature than coolant, but a couple of issues will also arise if you use only it in your cooling system: The engine gets more prone to overheating.
What can I use instead of coolant?
Water by itself can't do the job of antifreeze due to its lack of boiling and freezing point range and its inability to protect your vehicle's engine. Plus, it doesn't absorb heat as effectively. In the case of an absolute emergency, you can use water in your coolant rank.
Can you mix coolant?
The short answer is that you can mix different coolant brands and mixtures as long as they are the same type of coolant. The color doesn't matter as much since it's just a dye.
What happens if you put too much antifreeze and not enough water?
Most of the time, excess coolant is expelled from an overflow hose. You'll likely see a puddle of coolant beneath your car if this has happened. In worst case scenarios, overfilling your antifreeze tank can lead to electrical damage if overflow comes into contact with engine wiring.
Anti-freeze vs. coolant
When you hear the term anti-freeze and coolant, they refer to a fluid within your vehicle's cooling system. This fluid is responsible for reducing the engine temperature as it exceeds the maximum threshold to maintain the engine and prevent engine overheating that could damage it's completely.
How much coolant does my car need when empty?
Your vehicle is expected to hold up to five liters of coolant. You can purchase the coolant in one to 20 liters, and there's a lot of flexibility in terms of how you've purchased it. However, automotive experts recommend that you purchase only whatever you need and not more.
How do you know if your car needs antifreeze?
When you hear this question, you should immediately realize that your vehicle needs coolant, a mixture of water and antifreeze, which is why it was important to differentiate between antifreeze vs. coolant.
How often do I need to change the coolant?
In general, you will coolant needs to be flushed once every 100,000 miles. However, if you're driving an older car, you might want to flush it out more frequently. The best recommendation is to check with your vehicle owner’s manual and know how often to change your vehicle's coolant.
Antifreeze vs. coolant: final thoughts
Understanding the biggest difference between antifreeze and coolant is essential information for any driver. Both terms refer to the fluid used in the cooling system, but they don't mean the same thing.
Antifreeze vs. Coolant: How They Differ
Antifreeze and coolant are similar in many respects, and they share the same purpose. However, they are not the same.
What Does Coolant Do?
Coolant sits in your car’s radiator when the engine is off. Once you turn the ignition, the coolant travels through the engine’s nooks and crannies to absorb the heat that’s generated while the engine powers your vehicle. After a pass through the engine, the coolant is sent back to the radiator and cooled by the air.
Pure vs. Premixed Antifreeze
You can purchase pure antifreeze at any auto parts store. This antifreeze can then be mixed with water and added to your car’s cooling system. Another option is to purchase antifreeze that’s already been premixed with water to make engine coolant.
Is Antifreeze Toxic?
Whether it’s pure or premixed, antifreeze is toxic. The ethylene glycol it contains is harmful to both humans and animals. For this reason, it’s essential that you follow the manufacturer’s instructions when disposing of this liquid.

Antifreeze Vs Coolant
Most car owners use the terms antifreeze and coolant interchangeably, but the truth is they are completely different products. Antifreeze is the base ingredient of engine coolant made of either ethylene glycol or propylene glycol. To make engine coolant, you need to mix equal parts of antifreeze and water.
How the Cooling System Works
Before learning the importance of using proper engine coolant, you should understand how the cooling system works. This will give you a better idea of why you should use coolant instead of water.
Why You Should Not Use Water as a Coolant
It is not that you cannot use water to cool your car’s engine. You can use it if you want to, but I strongly advise against it. Here are the reasons why using water as a coolant is not a good practice:
What Type of Engine Coolant Should You Use?
You do not just use any coolant you can find. There are certain things you need to consider when choosing engine coolants. The first thing that you need to know is what type of engine coolant do you need? In this regard, you will be choosing between Type A and Type B coolants.
Different Colors of Coolant
Aside from the type, you should also be wary of the color of coolant your car uses. The different colors come from the dyes added by the manufacturers. This is to differentiate their base compounds.
FAQs – Antifreeze vs Coolant
Even though engine coolant does not evaporate as quickly as water, it still does evaporate over time. This is why you will always need to check the coolant level regularly.
Conclusion – Antifreeze Vs Coolant
Antifreeze and engine coolant are similar products, but at the same time, they are also different. Antifreeze is the base compound used for making engine coolants. It is a glycol-based substance that you should dilute with distilled water to make engine coolant.
What is the difference between coolant and antifreeze?
What's the Difference Between Coolant and Antifreeze? Put simply, coolant is the product you put into your car, while antifreeze is the active ingredient in coolant that requires dilution.
What is coolant in a car?
What Is Coolant? Coolant is a mixture of antifreeze and water, often a 50/50 ratio. It's pumped through the engine and heater core of a vehicle to absorb excess heat. Then, it goes through the radiator to dissipate the heat to the outside air. The coolant continuously runs through the system but breaks down over time.
Does antifreeze have additives?
Third, antifreeze has additives in it such as silicates, nitrates, and phosphates to protect against corrosion. Water helps to suspend those additives. Without water, the additives will often settle into your vehicle's system. When that happens, you lose protection against corrosion.
Does antifreeze transfer heat?
Higher Heat Transfer Capability. Second, pure antifreeze is not as effective at transferring heat out of the engine and heater core. When you are driving on a hot summer day, this becomes more important to avoid overheating your vehicle.
Does water help cool an engine?
Water can help to keep your engine cool, but it doesn't work nearly as well as coolant. Water boils faster and at a lower temperature than coolant and will freeze at a much higher temperature. While distilled water could be a bandaid in an emergency, it's always better to use the proper coolant to avoid costly problems.
Does antifreeze freeze before coolant?
First, despite the name, 100% antifreeze will actually freeze before coolant at temperatures between 0 and -5 degrees Fahrenheit. Coolant with a 50/50 mixture has a freezing point of -35 degrees Fahrenheit. Further, a 70/30 mixture of antifreeze and water drops the freezing point lower to -84 degrees Fahrenheit.
What Is Antifreeze?
We start the discussion by looking at antifreeze. It is a common item in most garages and spare part shops. It is a liquid added to water to alter its changes when exposed to temperature changes. It lowers the freezing point and raises the boiling point of water.
What Is Coolant?
On to the next part of our discussion, we look at the coolant. As earlier hinted, it is a mixture of water and antifreeze, where the latter substance makes the water more efficient in heat regulation. The combination is typically 50/50 for water and antifreeze.
Antifreeze vs. Coolant Differences
After answering, what antifreeze does, you can see the contrasting points. Antifreeze is the substance added to water to alter its boiling and freezing points. On the other hand, coolant is a mixture of water and antifreeze. You also learn that there are coolants that do not use water.
Summary
A coolant is an essential item for your vehicle’s engine, aiding in temperature control. At times, it goes by antifreeze, which by now you realize are different things. As a vehicle owner or enthusiast, this article will guide you in understanding the variations between antifreeze and coolant.
What is antifreeze made of?
Antifreeze is made of ethylene glycol or propylene glycol and is the basic ingredient, but it has to be mixed with water to create coolant, which is the cocktail you will find in the cooling systems of all “water-cooled” vehicles. Coolant typically consists of a 50-50 mix of antifreeze and water, though it can contain as much ...
How does coolant work in a car?
When the engine is running it gets pumped through passageways in the engine to absorb heat and then goes back through the radiator, where it is cooled by fresh air before circulating through the engine again. When a vehicle’s heater is being used, some coolant gets diverted to the heater core; the coolant warms the heater core, ...
Can you mix antifreeze with water?
Adding small amounts of straight antifreeze to top off the cooling system won’t upset the cooling and boiling protection, but the best practice is to mix it with the appropriate amount of water.
Can antifreeze be mixed with other antifreezes?
Among the different types of chemistry are inorganic acid technology, organic acid technology and a hybrid of the two. They shouldn’t be mixed with each other.
Does antifreeze freeze?
Overheating can warp engine parts, and liquid expands when it freezes, so that can crack engine blocks and other parts. Using straight antifreeze won’t provide more protection against freezing. The freezing point of antifreeze alone is zero, but a 50-50 mix with water lowers the freezing point to minus 35 and raises the boiling point to 223 ...
