Antifreeze is the general name for liquids that do not freeze at low temperatures. Including those intended for cooling automobile engines. Antifreeze is a brand of antifreeze developed during the Soviet era. Considering that the Tosol brand was not patented by any copyright, many domestic manufacturers call their low-temperature coolants antifreeze.
Instructions
Step 1
At present, the coolant can be called antifreeze only if it complies with TU 6-56-95-96. Antifreezes differ in their composition by additive packages. This means that their quality, applicability for different engines and service life are not the same.
Step 2
It is widely believed that antifreeze is applicable to domestic engines, and antifreeze - to engines of foreign cars. Following this opinion, many domestic manufacturers of coolants began to call their products antifreezes. Thus, as if hinting at the possibility of using their products in engines of foreign cars. Remember: only one indicator should be considered when choosing between antifreeze and antifreeze - the approval of this brand of coolant by the manufacturer. You can find out this in the service book for the car or on the manufacturer's website on the Internet.
Step 3
Despite the advice of many motorists, it is impossible to distinguish antifreeze from antifreeze by color. Both antifreeze and antifreeze are initially colorless. Each manufacturer is free to add any dye it deems necessary. For example, some domestic enterprises may produce the same brand of antifreeze or antifreeze with different colors.
Step 4
Often on advertising booklets for antifreeze or antifreeze of a domestic manufacturer, its applicability for engines of many foreign cars is indicated. In fact, it could very well be a hoax. For example, antifreezes for BMW and Opel cars are different in their composition and properties. No coolant brand can match these engines at the same time.
Step 5
The foaming rate of antifreeze or antifreeze is associated not with the car, but with the car factory. So for domestic antifreezes, the foaming rate is much lower than for imported antifreezes. In fact, this indicator is important for the manufacturer and is associated with the specifics of a particular type of production.
Step 6
Many imported antifreezes do not comply with the national GOST. This does not mean that they are of poor quality. The fact is that GOST was developed for traditional coolants, and, according to experts, is outdated and incomplete. Therefore, if the manufacturer requires the use of a brand of coolant in a car that does not comply with GOST, this does not mean that it is of poor quality and cannot be used.
Step 7
Mixing different brands of antifreeze and antifreeze is strongly discouraged. Their additives can react with each other and cause damage to engine parts. If it becomes necessary to change the coolant, change it all completely. Pre-flush the cooling system with distilled or boiled water. And stock up on some of the same brand of antifreeze in case you top up. As a last resort, top up with distilled water.
Step 8
You can distinguish high-quality antifreeze or antifreeze by the presence of a quality certificate from the seller, by the quality of the canister and cork, by the presence of degrees of protection against counterfeiting. In addition, antifreeze or antifreeze should not have turbidity or sediment; when shaken, the foam should settle within three seconds. Be sure to check compliance with the requirements of GOST, TU or standards of foreign manufacturers, manufacturer's coordinates, production date and expiration date.
