What do antifreeze and coolants do? How they benefit you? And why do you need them?

What the 2 fluids do is pretty straightforward and simple. First and foremost, antifreeze and coolants serve very similar purpose. These chemical fluids, often colored, are added to an automobile’s radiator or reservoir to manipulate the temperature of its engine. It lowers the freezing point, and also, simultaneously increases the boiling point by several degrees so that the engine does freeze as fast during the winters, and does not overheat and boil down as quickly as it should during hot summers.

So basically, what antifreeze and coolant does is that it extends and pushes the freezing and boiling points of your automobile’s fluid so that it reaches the points later and than usual. In another words, it increases your automobile engine’s resistance and immunity to and from freezing and overheating. One other way antifreeze and coolant benefits you, the engine that is, is by acting as a lubricant to the operation. It lubricates the moving components it comes in contact with to ensure a smooth and easy operation. Therefore, there are 3 very important reasons as to why you need it:

  1. Lowers freezing point to delay freezing
  2. Increases boiling point to delay overheating
  3. Lubricating


Things you should know about antifreeze and coolants


Antifreeze versus coolant

Antifreeze and coolants, as the name may give away, sound like they do opposite jobs. This contradictory name has had a lot of drivers and learners confused at first, but the truth is: antifreeze and a coolant serve the same purpose, and more or less have the same chemical properties. In fact, they are often referred as the same thing.


These fluids are highly hazardous to health if ingested or in topical contact for too long. Antifreeze poisoning is fatal could lead to discomforts and health issues like blood in urine, blindness, dizziness, unconsciousness, and even coma. Keep the fluid containers away from the reach of children and pets. Lock it away in a cabinet if possible. Always be sure to sure use the fluids carefully as to not to spill it on your skin or eyes. If ingested, immediately run to the nearest hospital or contact poison control.


What type of antifreeze coolant should be the best for my car?

This is a tricky question to begin with. Anti freeze and coolant will work the same way in almost all automobiles, given there are some exceptions in larger vehicles like trucks. However, the best one for your car can be found only through trial and error, or from the recommendations from your fluids’ application chart.



Before you put antifreeze coolant into your car, test the previous fluid to check for expiry. If it has gone bad, you can go ahead and refill. You can check if the fluid has gone bad buy checking it color which changes into a muddy brown color or checking its pH which tends to become more acidic; you can test through pH strips, by the color, by a temperature meter or even by digital testers. Be sure to change and maintain regularly since the bad fluid is acidic and can eat away the metal.


Things to look for when buying antifreeze and coolant

Let’s be honest here, taking the shortcut right to the 6 Best Engine Antifreeze and Coolants part of the article  is not going to do you any good if you do not make sure of a few important before the purchase. However, you do not have to dig too deep to learn about antifreeze coolants. Knowing about this only point should have you covered for the best part:

  1. Identify the coolants

There are basically 3 types of coolants in the market today:

  • Inorganic acid technology (IAT)

This type of coolant is bets for cars manufactured from the 1920s to the late 1990s. This coolant is clear is color, but often dyed bright neon green for easier identification. IAT coolants contain silicates and phosphates corrosion inhibitors to help protect metal parts of the car through which it runs through: engine and radiator. It is advised IAT to be flushed out of the cars every 2 years, or after 30000 miles.

  • Organic acid technology (OAT)

This type of coolants comes in various dyes including orange, pink, and red to dark green. It does not contain silicates and phosphates to protect the car’s metal from corrosion. OAT coolants last very long and require less frequent flush outs, but they still do eat away the metal at the end of the day. OAT coolants are best suited for cars from GM, Honda, Toyota and VW.

  • Hybrid Organic Acid Technology (HOAT)

This type of coolant contains silicates and additives, which protect the car’s metal components.  It is usually dyed yellow or orange, but is not limited to it. HOAT coolants should be flushed out every 5 years or after every 150000 miles. HOAT coolants are best for Asian cars, German cars, and European cars.


While there are any other points to look into, there is none more important than understanding getting the types right. But, for more accurate choices, check with your car owner’s manual or consult with an auto expert.
