Difference Between Coolants And Antifreeze

Many people get confused about the difference between antifreeze and coolants. However, these are in the same category. Antifreeze and coolants are exactly the same solution.

They can keep the car engines including the liquid on the radiators from freezing during the icy weather while also preventing the engine from overheating by utilizing the lubricants in the coolant to grease up the engine parts.

Years ago, the normal type of antifreeze is ethylene glycol (EG) based and it is colored green. EG is an antifreeze and a coolant in one solution with a high heat transfer. It prevents engines from freezing and acts as a coolant for engines during summer.

However, this is highly toxic to mammals. Then propylene glycol (PG) was introduced. PG comes from glycerin or petroleum and also has an antifreeze and coolant elements.

Today, antifreeze/coolants are generally mixed up with various elements for specific use for certain car models. They also have varying colors which represent their components.

Types of Antifreeze:

  • Inorganic coolants which are usually green in color utilize the Inorganic Acid Technology (IAT) in its formula. It can be composed of EG and PG. It has a service distance of 30,000 miles (50,000 km.) before it must be replaced.
  • Organic coolants use the Organic Acid Technology (OAT) in manufacturing. The formula can be EG based or PG based but usually it’s more on EG based with the usual color of orange and red. However, green, pink and blue also represent OAT coolants. Service distance is 150,000 miles (250,000 km) and then must be replaced. OAT should not be mixed with other coolants or this can cause corrosions.
  • Hybrid Organic Acid Technology (HOAT) is a combination of OAT and IAT. It sometimes comes in orange or in yellow liquid form. Normal service distance is 150,000 miles or 5 years equivalent.
  • Nitrited Organic Acid Technology (NOAT) is basically OAT with added nitrite. It can be used on all types of vehicles. NOAT and HOAT have almost the same performance but its service life and distance covered is yet to be established.
  • Universal antifreeze coolants are also known as the 50/50 premix antifreeze/coolants. This means 50 percent distilled or demineralized water is already added to the solution and no need to add water during use. These types are mainly EG based mixed with low amount of silicate to protect engine parts and the radiator from corrosion as well as the aluminum parts.

Note: All types of antifreeze come out of the mixers without color but clear. But due to their formulation and for marketing purposes of manufacturers, they are added with dyes for easy identification. In addition, avoid mixing types of coolants unless there are universal coolants in it because once chemicals get mixed up, this could form into gel which can restrict flow of liquid from radiator to the engine and can cause problems.

Wrapping Up: What’s The Best Antifreeze?

When using antifreeze/coolant, it is best to comply with your car user’s manual or read the label on the containment because not every antifreeze can be suitable to all car models or brands as the new breed of cars today have other metals in their engines that may get harm with some of the antifreeze components.

These products on our list will surely serve their purpose because they were carefully chosen and regarded as the best antifreeze in the market according to the consumers/reviewers who have used it for years.
