What is antifreeze?

Sometimes car enthusiasts ask an insignificant, at first glance, question – how to choose antifreeze for the car? First of all, let’s give its definition. Antifreeze for the car is a liquid substance that performs the cooling function, protecting the engine from overheating. The correct work of the car in the cold season depends on the quality of the coolant. That is why it is necessary to choose it thoroughly, try to understand this question before buying. Well, if your car is in such bad shape that it’s too late to choose antifreeze, you can go here: https://towingandscrapcarremoval.ca/scrap-car-removal-etobicoke. They give good money for old cars:

The coolant is selected by car brand. First, we recommend reading the instruction manual for the car. No one better than the manufacturer will give advice on what antifreeze should be poured into the car. There is a practice of laboratory testing at the factory. In this case, the manual specifies a particular brand of coolant, which is better suited to the vehicle.

The antifreeze is a lubricant-coolant consisting of ethylene glycol, water, additives (the package depends on the specific manufacturer), which ensures that the liquid does not crystallize at low temperatures. A good substance must be in equal contact with silicone, plastic parts included in engine cooling system.

Antifreeze technically includes types of fluids:

Water + mineral salts. Not considered a good coolant because of the rapid precipitation of salts, which improperly affects the cooling system.

Water + ethylene glycol. Has similar nuances to the first type.

Water + glycerin. Dangerous substance, banned by law. Excessive viscosity of glycerin is reduced by inexpensive methanol. The resulting product is poisonous and dangerous. Methanol boils off at temperatures from 95 degrees (a measure of normal engine operating temperature) and burns. This makes it unsuitable for use as part of the coolant. Also glycerine-methanol fluid turns in a very short time (about two months) into a water-glycol mixture that creates corrosion.

Tosol. Developed in the USSR, fits the old requirements.

How to choose the coolant

Choosing the right coolant is quite difficult. On sale there are a lot of fakes with glycerin, methanol. It is difficult for the average buyer to distinguish the counterfeit product from the quality product. The labels of fakes have no information about the banned substances in the composition, and such products are cheap. A low-quality fluid damages the engine oil, starting to oxidize much faster than it should. And corrosion, starting to develop in a car, will lead to rotting of radiator tubes, pump impeller and other unpleasant consequences.

This can be avoided if the producer diligently adds the necessary additives. They make up 3-10% of the whole mass of the liquid, this insignificant amount considerably influences the quality of the coolant mixture. With additives antifreeze lasts for several years, the risk of corrosion is considerably reduced.

Types of antifreeze

Antifreezes are divided into several kinds, depending on the additive package:

With organic additives (carboxylate)

With a mixture of organic and inorganic additives (hybrid)

With inorganic additives (silicate).

It should be noted that the opinion that the color of the antifreeze is characteristic of the coolant of different quality is a myth. Remember – the color has no effect on the technical characteristics. Manufacturers use different dyes – that’s the only reason antifreeze has different shades. Do not choose coolant by color, so you will not get the desired result. Originally, the bright shade of antifreeze was supposed to help the driver. Antifreeze leaks, the motorist sees a characteristic color and understands that the cooling system is leaking.

When topping up the coolant, don’t be guided by the same color rule. If your car was previously filled with green colored antifreeze, there is no guarantee that a green colored fluid from another manufacturer will work. The safest option is to completely replace the antifreeze with a new one, following the vehicle manufacturer’s tolerances and instructions.
