What Type of Coolant Does My Car Need

What Type of Coolant Does My Car Need?

Engine coolant prevents your engine from getting too hot and helps you avoid expensive maintenance expenses. Coolant assists in safeguarding your engine against extreme temperatures, whether high or low. Your car’s engine becomes too hot during operation, reaching temperatures that can potentially harm vital components. 

The coolant takes in the heat from the car’s engine and then moves back to the radiator. In winter, very low temperatures can freeze and damage your engine block. Coolant helps to avoid both excessive heat and freezing. As its name suggests, engine coolant, often known as antifreeze, does not solidify in temperatures below zero. 

Engine coolant, also known as antifreeze, includes components that prevent corrosion of the engine elements in your vehicle. Engine coolant is available in several types, but its main features include ethylene or propylene glycol and water.

What are the many kinds of engine coolant?

Various kinds of engine coolants are specially designed for multiple sorts of automobiles. Coolant types are classified based on their name and color. It is advisable to consistently utilize the kind of fuel that is recommended for your vehicle. Six different varieties of engine coolant are:

Inorganic additive technology (IAT)

The color of the IAT engine coolant is green. The composition includes ethylene glycol together with silicate and phosphates to prevent corrosion. It is commonly found in older vehicles, primarily cars made in the United States before the late 1990s. Being an older recipe, it is less effective than many modern varieties of engine coolant. If your automobile needs IAT coolant, you should flush and replace it every two years or every 24,000 miles. IAT formulations include silicates, which safeguard your car’s engine by preventing corrosion.

2. Organic acid technology (OAT)

OAT engine coolant is formulated using a propylene glycol base. Engine coolant that uses organic acid technology (OAT) is often orange, although it can also be found in different colors, such as dark green. Always verify the label to avoid mistakenly selecting a color corresponding to another coolant type. This coolant is generally suitable for GM, Saab, and VW cars.

3. Hybrid organic acid technique (HOAT)

Hybrid organic acid technology is one of the three primary engine coolant classifications, encompassing other subcategories. Traditionally, HOAT coolant had a yellow color. It is currently available in a variety of hues. HOAT coolant is available in various colors, including yellow, orange, green, pink, and blue. When selecting the appropriate HOAT coolant, it is advisable to consider the brand name rather than the color of the liquid.

The HOAT formulation combines the OAT formulation and the IAT formulation. HOAT utilizes silicates and organic acid to safeguard your engine and counteract corrosion. The replacement frequency should be the same as that of OAT coolant: every five years or every 50,000 miles. If you own a Ford, Chrysler, or European vehicle, it will utilize HOAT coolant.

Phosphate-free hybrid organic acid technology (HOAT)

Phosphate-free HOAT typically has a turquoise tint. This formula, which does not use NAP, is created using ethylene glycol and includes corrosion inhibitors of both organic and inorganic nature to safeguard your engine. The product does not contain phosphates, such as nitrite, nitrate, and borate. Additionally, it is a formula with minimal silicate content.

Phosphate-free HOAT can be utilized with various car brands, including BWW, Volvo, Tesla, Mini, Audi, Jaguar, Mercedes, Porsche, Rolls-Royce, Saab, and Volkswagen. The formulation without phosphates is designed with the protection of your car’s gaskets and seals in consideration.

Phosphorylated HOAT

Phosphate HOAT employs phosphates and organic acids to prevent corrosion of the components in your engine. The coolant is typically pink or blue.

Phosphate HOAT coolant is typically suggested for usage in Asian-made vehicles, including KIA, Honda, Hyundai, Nissan, and Toyota vehicles. Because of heat transfer problems, Asian automobile makers must utilize this coolant. The coolant uses carboxylates and phosphates, instead of silicates, to prevent corrosive activity in your car’s engine.

6. Silica-based HOAT

Silicated HOAT is typically identifiable by its vivid purple hue. It utilizes silicates and organic acids to prevent corrosive activity in your engine. The formula does not contain nitrites, nitrates, phosphates, borates, amines, or imidazole. Instead, it utilizes silicate, organic technology.

Which coolant is the most suitable for my car?

The optimal engine coolant for your car is determined by factors such as the type of vehicle, its age, and place of manufacturing. Being aware of the brand, model, and year of your car will assist you in choosing the appropriate coolant. Selecting the incorrect product may lead to subpar performance or immediate engine malfunction in more severe cases. Follow these suggestions to ensure you make the correct decision.

Verify the color

Various hues of coolant are associated with varied automobile compatibility. For instance, IAT coolant is commonly green, while HOAT coolant is typically turquoise. However, it is essential to note that hue may only sometimes be a reliable indicator of the appropriate coolant for your vehicle. There are alternative brands made for specific automobile models and countries of origin, which may come in various colors that can be perplexing. Use color as a reference, but read the packaging to confirm that the coolant is compatible with your automobile.

Visit the origin

Your car’s owner’s manual contains a lot of helpful information. The tool will indicate the most suitable coolant for your vehicle. You may likely get the necessary information online if you do not own a copy of your owner’s manual. The formulae recommended by your dealership and your owner handbook will likely be approved by the original equipment manufacturer (OEM). Still, there are also alternative options available in the aftermarket.

Remember to bring the water.

When replacing the coolant in your automobile, it is essential to check the instructions on the container to see if the formula should be diluted with water. Certain types of coolant can be directly poured into your car’s system without any additive, while other types are intended to be mixed with water in a 50/50 ratio. Using softened tap water will be effective.

 Conclusion

Whether you have expertise as a do-it-yourself mechanic or are new to car care, it is clear that you have a genuine concern for your vehicle. It is necessary to have the appropriate supplies to change your engine coolant.
