When refueling the car's cooling system, you should read the instructions containing information on how to dilute the antifreeze concentrate. It differs from the finished antifreeze, which does not require the addition of water. The composition of the substance is such that solid crystals do not form in it at low temperatures. However, before pouring, it is recommended to take into account the freezing threshold of the concentrate.
Varieties of coolant
The instructions for the substance indicate how to dilute the antifreeze concentrate. Information is placed on the packaging container or directly on the liquid container itself. The method of preparation of the coolant depends on the composition.
The following types of antifreeze are distinguished:
- Traditional - these were used by the owners of the domestic auto industry. Antifreeze and its analogues are classified as obsolete coolants, but some drivers still use a cheap tool. It is not diluted, but in warm areas, drivers can add water to save money.
- Hybrid - hybrid coolants. The composition includes several types of additives that have a beneficial effect on the internal cavities of the motor andcooling system. There are three types of substances depending on the manufacturer: Japanese and Korean origin - phosphates, American - nitrites, European - silicates.
- Lobrid - includes two types of inhibitors: mineral and organic.
- Carboxylate - durable. The long service life is due to the way the concentrate works: the active substances react only when corrosion has formed. After that, a protective film appears at the place where rust appeared.
General rules
Before you dilute the antifreeze concentrate, you need to familiarize yourself with the wrong options for the procedure. Violation of technology leads to costly car repairs. One of the important points in the preparation of coolants is the prohibition of mixing different types of inhibitors. For this, mixtures of their own color are often prepared.
But not always the same shade indicates a similar type of concentrate. If there is no certainty about the exact origin of the liquid poured into the tank, it is better to pour out the antifreeze. How to breed a new mixture, you can find out when buying at a car dealer.
It's often a 50/50 ratio when topping up antifreeze. Whether to pour undiluted concentrate is up to the car owner to decide. There are a number of disadvantages when using the substance without adding water:
- Replacing the coolant will become an expensive procedure.
- Additives that protect the metal from overheating and corrosion require water molecules to work properly.
- A thick mixture will heat up quickly and reach boiling point faster.
- The service life of the substance is reduced due to the low mobility of the mixture. The pumping unit - the pump - is designed for a certain viscosity. Due to the undiluted state, the node will fail faster.
Important coolant parameters
As a rule, they are guided by such basic criteria when choosing a coolant: the boiling point of antifreeze and the freezing point. Modern engines operate at temperatures above 100 degrees. Therefore, old additives are no longer serviceable.
By the way, you need to know not only how to dilute the concentrate. Antifreeze sometimes changes color over the course of its service life. It is on the shade of the mixture that many drivers are guided when they are going to change the coolant.
Life of Substances:
- carboxylate retain properties for more than 5 years;
- hybrid protect from 3 to 4 years;
- traditional work no more than 2 years.
Based on the service life, it is recommended to know how to dilute the antifreeze concentrate. After all, if you add a carboxylate mixture to the traditional version, you will have to change the liquid much earlier than the deadline. But a situation may arise when the substance thickens due to a chemical reaction. Then the operation of transport will become completely impossible.
Coolant preparation sequence
Let's consider how to breedantifreeze. The concentrate is stirred only with distilled water in an amount equal to the volume of the first substance. All manipulations are done before pouring into the expansion tank, using a clean container.
How to dilute antifreeze (concentrate) is known in any auto repair shop. In order not to make a mistake with the choice of a suitable remedy, it is recommended to consult with a specialist. Often car dealerships change fluids at their discretion. This may be due to mini-accidents during transportation, when pipes burst or tightening clamps were poorly tightened.
Rules for preparing the mixture
Only distilled water is added to the concentrate. Often, drivers add tap fluid. This will destroy the system much earlier, despite the presence of additives.
Tap water contains s alts, minerals, rust, and other deposits. They will quickly settle on the inner walls of the engine grooves under the influence of high temperatures. Experienced craftsmen recommend slightly overestimating the specified amount of antifreeze - this way the resulting solution will work more efficiently.
For proper mixing, all substances are added to a separate container, then poured through the neck into the vehicle system. It is important to prevent the formation of air pockets. If excess air is not released, individual cooling areas will quickly heat up and some of the additives will become unusable.
Why does the manufacturer not immediately prepare the coolant?
The concentrate contains the active substance ethylene glycol - this is 93% of the total volume. Such a mixture freezes at -13 degrees, which does not allow the car to be operated in the northern regions. When mixed with distilled water sold in car dealerships, a chemical reaction is observed. The resulting solution is already ready to withstand -38 degrees.
The second reason for supplying concentrate is to save space when delivering antifreeze to stores. When selling a ready-made cooling mixture, it would be necessary to find another half of the occupied volume in warehouses, which would certainly lead to a rise in the price of the product.

Extreme temperatures are one of the car's most insidious enemies. Both frost and strong heating negatively affect the operation of critical components of equipment, which affects both the efficiency of its operation and the degree of overall safety. Antifreeze is one way to prevent problems caused by high engine temperatures. Therefore, any motorist simply needs to know the answers to questions about how to check antifreeze
How to dilute antifreeze concentrate? Rules, tips
Any car engine has a cooling system. It removes excess heat and maintains the optimal temperature regime of the motor. Antifreeze or antifreeze is used as a working fluid in SOD. But store shelves also sell antifreeze concentrate, which is often chosen by motorists. Why is it special and how to dilute the antifreeze concentrate? We will talk about this in our today's article
Antifreeze concentrate how to breed? How to dilute antifreeze concentrate correctly?
Coolant is the lifeblood of an engine, keeping it at normal operating temperature, helping it warm up quickly in cold weather and stay cool under stress. And when temperatures drop below freezing, if the fluid is mixed with the right antifreeze, the coolant prevents damage. It performs another important role, as it stops corrosion in certain parts of the engine. The article will discuss how to dilute antifreeze concentrate
Antifreeze running out quickly? Where does antifreeze go, what to do and what is the reason?
In the event that antifreeze is running out, the cause should be identified and repaired as soon as possible. Constant overheating of the engine will soon lead to its breakdown. The reasons for the loss of antifreeze can be very different. In order to fix the problem, it is necessary to inspect all elements of the cooling system for leaks
