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.
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.
What's the difference between antifreeze and coolant?

What happens to a car without coolant or antifreeze?
Without coolant, there’s nothing to extract this heat, and these parts quickly overheat and break down. Can you run a motor without coolant? the coolant existing in the car’s engine system performs an important role in keeping the car running .
What are the three functions of antifreeze?
According to Jim Roberts, Shell's technical service specialist, coolant has three important functions: First, it must transfer combustion heat from a vehicle's engine to its radiator, where the heat is given off to the atmosphere; second, coolant must provide adequate protection from freezing and boiling; and third, it ...
How does antifreeze work in an engine?
How does antifreeze work? Antifreeze is a liquid which has a much lower freezing point than water and is added to the car's cooling system. The mixture is pumped around the engine by the water pump. As it passes through hotter parts of the engine, it absorbs that heat and the coolant is transferred to the radiator.
Why does an engine cooling system require antifreeze?
Antifreeze keeps the water in your radiator and engine from freezing in cold temperatures. Antifreeze also keeps that same water from boiling over in hot temperatures. Antifreeze also serves as a lubricant for the moving parts it comes in contact with, such as the water pump.
What is the difference between coolant and antifreeze?
Well, antifreeze and engine coolant are similar, but not the same. Antifreeze is a concentrated, glycol-based liquid that must be diluted with water before use – at which point it is referred to as coolant. Alternatively, you can purchase pre-mixed engine coolant, a ready-to-use solution of antifreeze and water.
Does antifreeze affect AC?
Yes, coolant can affect a car's air conditioning by impacting the car's temperature, humidity, and airflow.
Does antifreeze stop overheating?
Coolant/antifreeze is added to a vehicle's cooling system, which circulates the fluid throughout the engine and radiator to prevent overheating. If your vehicle's cooling system is functioning properly, it will effectively reduce the heat produced by the engine and keep everything running smoothly.
Does antifreeze improve cooling?
Without it, the heat from combustion would cause the engine to rapidly overheat, or even completely seize up. Antifreeze also lubricates cooling system components which come in contact with water, and keeps metal components from corroding.
Can I use water instead of antifreeze?
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.

At what temperature does a car need antifreeze?
At -36 degrees Fahrenheit (that's -38 degrees Celsius), antifreeze and coolant will start to solidify, making it very difficult for your engine to turn over.
Do you add coolant to radiator or reservoir?
If your engine is cold, the coolant level should be up to the cold fill line. Loosen the reservoir cap just a little, then step back while the pressure releases. Then, remove the cap completely. If the coolant level is low, add the correct coolant to the reservoir (not the radiator itself).
What is antifreeze in cars?
What is antifreeze? Put simply, antifreeze, also called coolant, is the lifeblood of your vehicle during cold winter and hot summer months. If you do not have antifreeze in your vehicle when temperatures drop, you may find yourself stranded somewhere you would rather not be. Your vehicle also may fail to start altogether. Both of these situations also happen because of overheated engines.
Why is antifreeze better than water?
Why does antifreeze do a better job than ordinary water? The chemical formula of antifreeze both lowers its freezing temperature and raises its boiling temperature. As such, when ambient temperatures drop below freezing, antifreeze prevents cold weather from damaging your vehicle’s engine. Further, when your vehicle warms up due to either normal functionality or high outside temperatures, antifreeze keeps internal engine temperatures under control.
What is the best ratio of antifreeze to distilled water?

When to replace coolant?
Unlike brake fluid and even engine oil, which may retain its appearance over time, coolant changes color as it breaks down. If your antifreeze takes on a rust-colored or brownish hue, it is likely time to flush it out of your radiator and replace it with a fresh supply.
Does antifreeze degrade over time?
The ethylene glycol or polyproline glycol in most antifreeze blends does not degrade over time. Still, antifreeze has anti-corrosion compounds that break down with ordinary usage. These compounds protect the metallic components in your vehicle’s radiator, engine, and other systems from rusting. If you do not occasionally replace antifreeze, sensitive parts of your vehicle may corrode.
Does a water pump circulate coolant?
As mentioned, your vehicle’s water pump circulates coolant throughout its engine cooling system. While you know that the pump moves antifreeze, you may also wonder if water would work equally as well. The simple answer is no.
