The cooling system maintains the temperature of the engine, making sure that it does not become too hot. It is very important for the coolant to flow properly in the water jackets around the engine to keep the operating temperature optimum.
But due to the weather conditions, sometimes the coolant cannot flow properly and may get frozen in the water jackets. The antifreeze solutions are used in these situations to keep the flow of coolant smooth and optimum.
There are many popular antifreeze items available in market, some of which will be discussed in this Best Antifreeze review depending on their benefits and lacking.
Invalid table id.What is Antifreeze Solution?
An antifreeze solution is a type of additive which is used in the cooling system of automobiles by mixing it with water normally. The function of antifreeze is to lower the freezing point of the coolant in cold weather regions. This prevents the coolant from freezing before reaching extremely low temperature and the flow remains smooth even in minus degree Celsius weather conditions.
Antifreezes also elevates the boiling point of coolants in case of extreme hot weathers, so that the coolant does not get boiled or evaporated easily in the ambient temperature soon after the vehicle starts running.

What to Consider before Buying Antifreeze?
Before someone buys antifreeze for the cooling system of his vehicle, he needs to select the one item that will be most appropriate to be used in his car. The user needs to know the parameters based on which he can judge the suitability of the product with his vehicle.
We will discuss some of the parameters found in best antifreeze products in this section.
The technology of the vehicle
- American automobiles generally use antifreeze with silicates and phosphate corrosion inhibitors
- Japanese automobiles use antifreeze which do not have silicates in it
- European automobiles use antifreeze having no phosphates
These are the common and generalized criteria for antifreeze selection based on the country of origin of the vehicle. The owner should keep it in mind first.
The formula of antifreeze
The formula that is used to produce antifreeze has a great impact on its usability with the various metallic parts of the car. The vehicles having an engine made of Aluminium use antifreeze produced
There are also many vehicles having radiators made of Brass or Copper. For those vehicles antifreeze made of IAT (Inorganic Additive Technology) formula can be used only.
The environmental laws
The geographic area where the vehicle is supposed to run has a lot to do with choosing the proper antifreeze. There are countries which consider environmental impact of the vehicle seriously and have different environmental standards which must be met.
Those regions might make the user go for organic antifreeze solutions which can be biodegraded. For developed countries like USA, Canada and many others, this is a serious criterion to consider before buying your product.
Weather protection
The main reason for using antifreeze is to ensure that the flow of the coolant will be proper and effective in both cold and hot weathers. It should always be made sure that the antifreeze reduces the freezing point and raises the boiling point of the coolant sufficiently, according to the weather of the region where the vehicle will be used.
Mixing issues
Some antifreeze solutions need the mixing of the antifreeze with the coolant (normally water) in different proportions (generally in 50:50 ratios) before the product can be used. The user must determine whether he can carry out this mixing process properly or not. If the user is unable to execute the mixing, he must only choose the premixed solutions.
Some Frequently Asked Questions (FAQs)
Q. Are Antifreeze and coolant the same thing?
Ans: both terms have been used for similar purposes overtimes, but they actually are not the same. Antifreeze is mixed with water to produce the coolant mixture. It is actually a component of the coolant mixture.
Q. Do I need to dilute antifreeze before use?
Ans: There are different antifreeze solutions available in the market, some of which are premixed. For premixed items, the user need not do any further dilution. In the case of other samples, the user has to dilute the solution as per instructed by the manufacturer.
Q. How much dilution might antifreeze need if it is not premixed?
Ans: This verily depends on the instructions from the manufacturer. The ratio of dilution will not be the same for all the products.
Q. How long does antifreeze solution serve?
Ans: This depends on the particular product. Some items may serve for a period of about two years or even more than that.
Q. Can antifreeze solutions cause corrosion or damage to the cooling system?
Ans: Most of the antifreeze solutions in modern days have additives which are corrosion inhibitors. Some of the solutions are made of OAT (Organic Additive Technology), which also can get biodegraded. These solutions will not harm the cooling system by any means.
If the antifreeze solution contains added silicates or phosphates in it, then in that case only some damages may be made to the cooling system. Such antifreeze should be avoided by the user.
Conclusion
Antifreeze solutions can help to get the best performance of the engine if they are chosen properly. The user should check all the important parameters before opting for a particular product. The wrong choice may cause some damages to the seals and gaskets of the cooling system by wear and corrosion.
Antifreeze should not only keep the coolant from being frozen, but it also should assure smooth flow of it by not forming any sludge inside the cooling system. A user should always care about this fact.
One particular antifreeze item may not always be able to serve cooling system of all type of vehicles properly. So choosing one of the popular items for your car without considering its compatibility with your vehicle would not be wise.
This Best Antifreeze review article should guide the user to select the perfect antifreeze solution for his vehicle thoroughly.
