Classification of car engine coolant and things to know

Are you looking for the right coolant for your car? Coolant is an indispensable product during the operation of liquid-cooled engines. Choosing the right coolant is very important to protect the car engine and ensure the efficient operation of the cooling system.
Let's learn about the classification of car engine coolants and things to know when using the product with BlueOne.vn!

Why use car engine coolant?

We need to understand it in an easy-to-understand way as follows. The car engine works by burning fuel in the combustion chamber to create energy, this process generates a lot of heat. At this time, the cooling system on the engine works to maintain a stable temperature and prevent overheating, the coolant plays a role in transmitting heat from the engine to the radiator. When using poor quality coolant, it can cause overheating and cause engine problems.
Therefore, car engine coolants are used to absorb heat and reduce engine temperature, and have the role of transferring heat energy from the engine to the outside through the heat dissipation process.

When using poor quality coolant, the heat exchange process will not take place well, causing the temperature in the engine to increase and damage engine parts such as: bearings, cylinders, pistons, valves, combustion chambers and other parts. In addition, when using poor quality coolant in the long term, it will cause rust on engine parts, even puncture the radiator.

So which car coolant should you buy? Below are the types of car coolants you should buy. Please refer to them.

Classification of coolant solutions

There are three technologies for producing coolant: inorganic base IAT, organic base OAT and a technology that combines inorganic and organic called HOAT.

Inorganic radical IAT

Inorganic IAT technology is a technology that uses salt mixed with distilled water to lower the freezing point. To avoid rusting the equipment, do not mix NaCl salt but use liquid glass salt or silicate Na2SiO3. This technology is the cheapest because silicate is cheap. However, it has two disadvantages: short solution life and heavier solution density than water, making the solution circulation slow, leading to slower heat dissipation efficiency. Silicate salt solution is cheap, but after 2 years of operation, the sludge layer separates, so the entire cooling system must be discharged and replaced with a new solution, leading to increased maintenance costs. If using inorganic coolant products, users need to pay attention to the coolant replacement cycle.

Organic OAT

OAT organic technology is a technology that uses Ethylene Glycol (EG) or Propylene GLycol (PG) mixed with distilled water to lower the freezing point of water to negative temperatures. OAT technology coolant solution has low density so water circulates quickly, leading to high heat exchange efficiency. OAT technology provides durable coolant solution with a lifespan of over 5 years.

The technology of combining inorganic and organic is HOAT

Inorganic-organic hybrid technology HOAT is a solution containing both Silicate and PG or EG. The trade name is often called Si-OAT. Hybrid technology has an average cost, heat transfer efficiency between the two technologies mentioned above and an average operating life, about 3 years of use.

The specific gravity of silicate (IAT inorganic technology) is high – close to 1.4 higher than PG or EG (OAT technology) – close to 1.1. At high specific gravity, the circulation capacity of inorganic coolant in the engine cooling system is reduced, resulting in a lower heat exchange efficiency than organic coolant, which will cause the engine to overheat.

Things to note when using car engine coolants.

When using car engine coolants, you need to note the following:

Follow manufacturer's instructions: You should follow the manufacturer's instructions on the type of coolant to use, its concentration, and replacement time to ensure the safety and efficiency of the cooling system.

Adjust the concentration: Adjust the concentration of the coolant according to the manufacturer's instructions. If the concentration is too low, it may cause damage. If the concentration is too high, it may reduce the cooling efficiency, which is not good for the engine and is wasteful.

Regular Replacement: Coolant should be replaced periodically to ensure the stability and efficiency of the cooling system. The replacement period is usually around 2-5 years depending on the type of coolant being used or according to the manufacturer's instructions.

Regular check: You should regularly check the coolant level to ensure the cooling system is working properly. When you find the level is below the MIN mark, you need to add more to ensure engine safety.

Use the right type of solution: You should use the type of coolant recommended by the manufacturer and not use solutions of unknown origin. Using the wrong type of solution will reduce the cooling efficiency and in the long run will damage the engine.

Protect your eyes and skin: When using coolant, you need to wear eye protection and protective clothing to avoid direct contact with the solution. Because it can cause irritation and damage to your skin and eyes.

Proper storage: Coolant should be stored in a cool, dry place.

Keep out of reach of children to avoid unwanted harmful situations.
