Coolant for Radiator

A car coolant is an essential automobile fluid that helps a car maintain optimal temperature during extreme weather conditions, both hot and cold. It prevents corrosion, increasing the lifespan of a car’s engine. Every car coolant comes with different specifications – each designed for a specific vehicle type. The color, concentration, and effectiveness of a coolant might vary depending on the manufacturer.

When purchasing a coolant, it’s essential to make the right choice. Picking up the wrong type can affect your car’s performance. As a car owner, you can study the manual to choose one the automaker recommends for your specific model. Most car owners find it challenging to select the best car coolant for their cars, leaving them in a dilemma while making the final call.

The best way to make a perfect choice is to learn how each coolant works. This will help you choose the best option for your car, saving you money. Though many manufacturers claim they offer the best car coolant, it’s always a good idea to research before grabbing the one that fits your car’s needs.

This blog will help teach you about the different types of coolants.

Types of Car Coolants

Organic Acid Technology (OAT)

The Organic Acid Technology coolants use propylene glycol as the primary ingredient. Being one of the most recommended car coolants by modern car manufacturers, the best thing about this type is its longer lifespan, requiring flushing once in 5 years. The extended life cycle of these coolants makes them a popular choice among car owners. As the name suggests, they rely more on organic acids and mostly come in orange, but the color may vary depending on the manufacturer.

Inorganic Additive Technology (IAT)

The InOrganic Additive Technology coolants are a popular choice for older cars. Unlike advanced car coolants, they require frequent check-ups and changings. These car coolants often use silicates and ethylene glycol as primary ingredients. Despite using old technology, these coolants maintain their popularity among the masses due to their affordable pricing and easy availability.

Hybrid Organic Acid Technology (HOAT)

Today, Hybrid Organic Acid Technology (HOAT) enjoys great fame among car owners. Its immense popularity stems from its anti-corrosion properties due to ingredients containing organic acids and silicates. The HOAT car coolant is a mix of OAT and IAT formulation, making it the perfect choice against rust and corrosion.

We can further classify the HOAT coolants into two categories.

  • Silicated HOAT:
  • The silicated HOAT uses silicates along with organic acids instead of phosphate. Most premium car manufacturers like Mercedes, Audi, and Volkswagen recommend this coolant for their cars. They might come in different colors, but the purple color remains standard among various manufacturers.

  • Phosphated HOAT:
  • This type of HOAT uses phosphate along with organic acids instead of silicate. It often comes in colors like pink or blue. It uses organic acids to help car owners eliminate rust and corrosion. Car manufacturers like KIA and Hyundai recommend this product for their cars.


Choosing the right type of coolant makes a massive difference for your car. It’s essential to select one based on your specific car requirements and the weather conditions. If you live in a cold environment where temperatures dip below zero, your car needs an antifreeze coolant to protect the engine against harsh weather conditions. It can also play a key role in keeping your car’s engine safe against grime, dust, corrosion, and rust and also increase its lifespan.

Once you know how the different coolants work, you can make an informed decision for your car. The next time you purchase a coolant, ensure it addresses all your needs. With different manufacturers offering various car coolant solutions, you need to study the manual in detail to make the right choice. This will help you optimize your car’s engine’s performance and protect it against harm.
