Is your engine starts to heat more during long driving hours? then you should be more aware of this unnecessary heat. It can harm your car engine and you too. Many drivers know that their vehicles need coolant, but some drivers might not sure which type to use, or which engine coolant to use first. In this article, we will answer all the questions that we often encounter in mails and social media comments.

Like oil, the basic function of the coolant is to transfer heat and increase antifreeze protection. Depending on your vehicle type, you may need a coolant with special additives or a coolant designed for high mileage vehicles. It is believed that the engine coolant failure can be the leading factor for engine downtime.

There is no engine cooling system is maintenance-free. Over time, each component starts to degrade and so does the coolant. Dilution with water and storming of outsider particles into the cooling system are the factors that can cause chemical degradation.

What does coolant do for my engine?

The coolant will only perform well if it retains its original composition. The transformed version may cause fluctuations, with disastrous consequences for the engine. The main aim of the coolant is to transfer heat and prevent engine damage due to freezing or boiling. The liquid in the system can only transfer heat impressively, so it is essential to prevent the coolant from freezing or evaporating.

In addition, if the coolant boils, the vapors formed do not transfer heat well, which means that if the coolant is not in contact with certain places where cooling is required, the engine metal will actually melt. Some modern vehicles have closed engine compartments and poor airflow, which means that without an effective cooling system, they may overheat within minutes.

What problems can cause by using the wrong coolant?

If there is no proper coolant in your system, corrosion and component damage may cause long-term effects. They are sometimes latent, which means that corrosion damage, deposits and blockages can take up to a year to cause problems.

Drivers often mistake it for a radiator failure, rather than simply admit that the wrong coolant was used. If the radiator is severely corroded or the internal fouling is blocked, it is likely to be the cause of the coolant system failure.

How often should I change my engine coolant?

When determining how often to change the engine coolant, the best way to refer to is the car manual. Each manufacturer has different recommendations that are worth sticking to. With the improvement of engine technology, the time interval between coolant replacements has been steadily increasing.

In many modern vehicles today, the cooling system is designed to last up to 10 years (or 200,000 miles) before adding new coolant. In fact, some vehicles are full of life. For your vehicle technology and engine, properties follow the user manual for a specific answer.

The pre-mixed UNI advanced formula coolant is developed by Gars lubricants, which has a longer service life than general-purpose coolants, which not only helps you protect critical engine parts (such as gaskets and elastomers) but also extends vehicle use Lifespan and lower cost of ownership.

In addition, All vehicles are not manufactured in the same way: there are different types of construction materials, operating environment, variable flow rate, maximum temperatures and pressures. But what all of them have in common is that they need to be protected. Vehicle OEMs conduct extensive tests to determine which fluids (including coolants) should be used in the systems they develop.


Hope You get the proper basic information about engine coolant and tips to choose right for your engine. For further detail read the user manual or take an advice conversation with the best coolant manufacturer near you.
