Yes Easy. Antifreeze is hygroscopic and absorbs water even from humid air (like alcohol), which is why it changes every three years, even if the car has been in the garage all this time ...
Bender:
Mixes, antifreeze is a little heavier.
grandfather mikhey:
I don’t mix, I have enough money ....
Tuesday:
Of course, it usually consists of half of the water.
Paul:
If not mixed, how were the concentrates sold? There is anhydrous antifreeze, so water is contraindicated there.
Alexander Amaretto:
The basis of antifreeze is dist. water! Everything appears to be mixed, but this should be done as a last resort and upon arrival home, replace all antifreeze. Otherwise, there can be big problems in winter, of course, the antifreeze will not freeze, but you can ruin the pump, since diluted en. frieze turns to mush
Vladimir:
antifreeze IS ALREADY A MIXTURE!! YOU CAN DILUTE IN ANY QUANTITY!
Ivan Shirkov:
Antifreezes are usually slightly denser than water, and therefore heavier. Coolant requires a certain concentration of various substances and by adding water you can greatly change it, and this puts the engine at risk. If you do not want to completely change, then it is best to add the same antifreeze. For example, I always fill in organic antifreezes, they are safer to mix, besides, they are of better quality and last longer. In the last 8 years, I completely switched to coolstream premium on both machines (Ford Focus and Volkswagen Tiguan).
Application of coolants
With the choice of antifreeze, there are usually no particular difficulties. But when using it, there are some peculiarities.
When preparing a solution of coolant and concentrates, it is necessary to comply with the requirements of the proportion.
Antifreeze should be replaced as needed or on a maintenance schedule unless replacement is required during an engine overhaul. Do not mix coolants of different properties and types, as malfunctions of the cooling system may occur.
If the brand of antifreeze poured into the engine is unknown, then it is better to drain it all and purchase a new antifreeze. It is undesirable to mix different brands of antifreeze, since different sets of additives have different properties, and as a result of chemical reactions, their imbalance will occur. When mixing different reagents, malfunctions and ballast sedimentation, water pump breakdown, engine overheating, clogging of the cooling system, and overhaul of the power unit may occur. You should not save on buying antifreeze, as engine repairs will cost much more.
Antifreeze for a car engine is sold in a finished or concentrated state. Many motorists are accustomed to purchasing a concentrate in order to make the solution themselves in the required proportion. But we must not forget that only distilled water is needed to dilute the solution, and the proportion should be determined by the freezing point. Each time you need to use only the concentrate manufacturer's instructions.

Olga Voloshina:
Try. If you sink, it's harder; if you don't sink, it's easier.
Anton Veltistov:
A little harder. The density of antifreeze is 1.065-1.085 g / cm3, and water is 0.99-1 g / cm3
Mika da Vinci:
Ethylene glycol is used as antifreeze in Tosol. And, as you know, it is slightly heavier than water in density. (from 1055 to 11125 kg/m3, at 20°С)
Dmitry Lomonosov:
When it comes to cooling, then - water. Here are some advantages: low viscosity, which reduces power consumption for circulation, high heat capacity, low expansion coefficient. But the use of TOSOL (aka antifreeze with additives) is convenient due to the low freezing point.In addition, all these advantages are insignificant (although they have a place to be). Do not be surprised that uneducated people will say Antifreeze, this misconception is due to the main advantage - (see above) low freezing point.

antifreeze does not cool it absorbs excess temperature

Nitrogen is pretty cool...
mishka11111:
if the car is then antifreeze or antifreeze, and if you yourself, then water
Sergey Isakov:
Water has much more heat transfer. It cools the engine faster and cools down faster in the radiator (if it didn’t freeze!). Antifreeze heats up for a long time and cools down for a long time.
Maxim Filko:
What matters here is not what cools better (all of the above factors can be neglected), but what lubricates the pump better (Which will not work on water for a long time). Bottom line: if there is a desire to ride on the water, it is better to refuse it.
because water does not have a beneficial effect on the pump, not to mention the scale that water provides!
Joke:
It cools better what the cooling system is designed for! water and antifreeze have different not only boiling and freezing points, but also heat capacity, viscosity, expansion coefficients, and heat transfer. And all this will affect the cooling of the liquid in the radiator. If the cooling system is made for antifreeze, then just water with a lower viscosity may not have time to cool in the radiator!

The fluid specified in the vehicle's instruction manual. Artifreez and Tosol, different things.
How to drain liquid
The answer to this question is very simple. The coolant must be drained in the following cases:
- If necessary, replace seasonally.
- When replacing the cooling radiator.
- When installing a new thermostat.
The work is done in two steps, since antifreeze is available in the radiator and in the engine. This work has already become familiar to owners of domestically produced cars.
You need to start draining the fluid from the radiator:
- Stop the engine.
- Wait 15 minutes for the engine to cool slightly.
- Switch the interior heater handle to the extreme right position. This will open the drain valve of the stove.
- Next, you need to open the plug of the expansion tank.
- Loosen the radiator drain plug.
- Wait about 10 minutes until the liquid is completely drained.
The coolant is drained from the engine as follows:
- Take a wrench and unscrew the drain plug on the engine block.
- Wait about 10 minutes until the liquid is completely drained.
- Wipe the drain plug and check the quality of the sealing gum, replace it if necessary, and screw the plug into place.
Care must be taken when draining antifreeze, as this liquid has a sweetish odor that attracts children and pets. Therefore, antifreeze or antifreeze must be drained into a container and disposed of, and not poured onto the ground
How to choose antifreeze for a car
Not all motorists can choose the right coolant for a car. Many of them believe that engine coolant is not that important. This opinion is quite common and is misleading.
Protecting the engine from defrosting the cylinder block in winter or overheating causes intensive use of the coolant. At the same time, its constant parameters change. The composition of the coolant used several times will not provide proper engine protection, but will only harm it.
Every motorist has ever faced the problem of replacing coolant for various reasons:
- The liquid completely changed its structure and color in the course of work.
- At the request of the car owner, for example, after a complete engine overhaul, together with the use of new oil, the coolant is also changed.
- During operation, due to periodic leaks, water or a liquid of unknown quality was topped up.
- The freezing point of antifreeze does not correspond to the operating conditions of the car.
- Fluid life expired.
Also, the reason for the replacement can be many other factors. Practice shows that car owners usually face the problem of replacing the coolant before the onset of winter. But this must be done regardless of the ambient temperature, but according to the conditions of maintenance.
The domestic distribution network offers a wide range of coolants of different trade names, colors and markings. There are also low-quality liquids that are counterfeit goods. In this case, instead of a high-quality cooling liquid, water painted over with a dye can be used. Often, chemicals are added to such fake liquids to increase its density.
This is done in order to prove to the consumer that this product freezes at low temperatures, since in real coolants, the greater the density of antifreeze, the lower its freezing point. Therefore, when driving a car using low-quality cooling fluids, serious problems can arise.
The most significant of them is a malfunction of the elements of the engine cooling system and interior heating. No one wants to run into a counterfeit product, creating the possibility of their car breaking down and putting themselves in danger. Let's figure out how to choose a liquid for cooling a car engine.
