The coolant is one of the vital fluids in automobiles. There are times when the temperature in your car or truck might become unbearable. For optimal performance, it will need to be cooled at these temperatures. When it comes to keeping your car’s engine cool, coolants serve an essential and vital role.

Coolants protect your car’s engine parts from corrosion and wear, allowing the engine block to last longer. Coolants come in a variety of hues, making it easy to find the right one. Colored coolants can be found in a variety of hues. It’s possible that not all coolants will work with your vehicle.

The coolant mixture will be different based on the type of vehicle and where and when it was produced. As a result, knowing which coolant is ideal for your vehicle is a must-have skill.

Check your owner’s manual before you buy coolant to determine what the manufacturer advises for your specific model of vehicle.

Green coolant properties

Red Coolant Vs Green

Inorganic acid technique is used to manufacture this common coolant. Propylene or ethylene glycol is the chemical basis for this AIT approach. phosphates and silicates are also present in this coolant blend.

However, compared to other coolants, this one necessitates more regular replacement. For example, you’ll have to replace it every two years.

It’s the only coolant that can be used on any vehicle, making it the universal coolant. Green coolants, on the other hand, are cost-effective. It’s built with special adjustments to keep metal from corroding in the cooling system of the vehicle.

Designed for older cars manufactured prior to 2000, this coolant has a higher copper and steel content than other coolants on the market. As a result, every 36,000 miles or three years of use, modern cars are advised to replace their coolant.

Red coolant properties

Red coolant, marketed as Dexcool, is a form of antifreeze that lasts longer than other kinds. Organic and inorganic acid technology are combined in the production of the oil. This antifreeze is the most stable of all coolants because it is created using modern technology.

In addition, it extends the life of the vehicle’s water pump. It is ideally suited for usage in modern and newer vehicles because of its contemporary design. The coolant should be replaced every 30 miles or every two to three years of use.

Differences between red and green coolant

Red Coolant Vs Green-2

  • Green coolants are the most common and conventional coolant types with an Ethylene Glycol base. In contrast, the red coolant has Organic Acid Technology as its base comprising the various green coolant’s chemical makeup.
  • The longevity of the coolants is another vital difference between the two. Red coolants often last longer than green ones.
  • Green coolants are ideal for older car models, while the red ones are best for modern cars.
  • The red coolant is more stable than the green coolant
  • The red coolant is produced by the hybrid technology, while the green antifreeze is made from the IAT technology
  • Red coolants use organic inhibitor additives like carbolic acid, while green coolants use inorganic additives like borate, silicate, and phosphate.
  • Red coolants need to be replaced after five years, while green ones need replacements after three years.
  • The red antifreeze is more expensive than the green one.

What happens if you put the wrong coolant in your car?

It is critical that you use the proper coolant in your vehicle. The coolant in ancient and new cars differs slightly, despite the fact that they all serve the same purpose.

The rubber, cast iron, and brass-based coolant systems of ancient automobiles were interchangeable, thus it wasn’t a problem to use them in any car model.

Today’s cooling systems, on the other hand, are made from different materials. Aluminum, steel, magnesium, silicon, nylon, and copper alloys, for example, make up the majority of their composition.

When it comes to your car’s cooling system, there are a number of variables that can affect the kind of coolant you require. This means that before a car owner decides on a coolant system, he or she should take into account the various elements.

Your vehicle’s performance will suffer if the improper coolant is used. It’s like putting the wrong coolant in your automobile when you use a mix of different types of coolant. It can lead to corrosion in your water pump, radiator hoses, radiator, and cylinder gasket.

When using a manual operation kit or a professional technician, it’s important to know what kind of coolant should be used.

What vehicles can use green coolant?

It’s likely that when you learn about the green coolant, you’ll hear that it was developed using Inorganic Additive Technology, which is a quite outdated formula.

The green coolant has undergone a number of modifications to improve its ability to prevent metal corrosion within the cooling systems of automobiles.

Green coolant is best suited for automobiles built before 2000 because of its older formula. Copper and steel, two common metals employed in the production of these vehicles, make up a significant portion of their overall composition. Antifreeze should be replaced every 3 years or every 36,000 miles.

What cars can use red coolant?

In comparison to other coolants, red antifreeze lasts the longest. Hybrid organic acid technology (HOAT), which includes a blend of OAT and IAT, enhances this property.

The water pump in your car will last longer if you use red coolant. As a result, in vehicles equipped with aluminum radiators, red coolant is recommended. Honda, Toyota, Hyundai, and Nissan are the four most common brands of automobiles that use red coolant.


Take care of your vehicle’s coolants because they can either lengthen or reduce your vehicle’s lifespan.

The only thing you need is an engine that will not hurt your engine and extend its lifespan by preserving it from corrosion and rust, as well as correctly controlling heat.

Make sure to consult your car’s owner’s manual or a professional before purchasing a new coolant.
