In order for a vehicle to last a long time, it is important to constantly care for it. Every experienced motorist knows about this. Maintenance should not be carried out at the request of the user or during repairs, but periodically. This is the only way to ensure that the car will not break down at the wrong moment.
Up to 80% of breakdowns are caused by untimely oil changes, improper operation of the vehicle, use of poor flushing agents, etc. It is the latter that need to be given a special role, especially when replacing motor fluid or repairing any system. This will avoid negative consequences and increase the reliability of the engine and individual components.
However, choosing a good vehicle is a difficult task that only experienced drivers can successfully cope with. To help you purchase the right product, the editors of the YaNashla website have prepared for you a rating of the best flushing fluids for 2020.

When is it necessary to flush the engine cooling system?
According to manufacturers' recommendations, you need to change the coolant and flush the system at least once every two years.
Sometimes the engine cooling system looks like this...
But, if it is not known when the procedure was last performed, you can make a decision based on a number of signs:
- the engine began to overheat more often;
- the pump works worse;
- the system's response to changes in the position of the rheostat has decreased;
- the temperature sensor shows an increased temperature or its readings begin to “jump”;
- the stove is not working well;
- The fan in the system always runs at high speed.
These are the first “bells” that the cooling system needs cleaning. If they are left unattended, the next symptom is boiling of the coolant.
How clogged the engine cooling system is, in some cases it is easy to determine visually: just open the radiator cap or expansion tank

How does the cooling system work?
Engine overheating, non-working heater, pump failure - problems with the engine cooling system occupy fourth place in the ranking of the most common automobile troubles. Not everyone knows, but most of these problems can be easily prevented and delayed as much as possible. You just need to keep the cooling system clean.
First, let's figure out how the engine cooling system works. Its key task is to maintain the engine temperature in the operating range due to the circulation of coolant.
Since immediately after starting the engine must reach operating temperature as quickly as possible, the cooling system is divided into two parts: a small and a large circle. The task of the first is to maintain the operating temperature, and the second is to remove excess heat. In a small circle, the coolant circulates as close as possible to the cylinders and heats up very quickly. As soon as it warms up to the highest operating temperature, the valve opens and the liquid flows into a large circle, already taking on the function of preventing overheating.
In addition to the cooling circuits, the system also includes a radiator with a cap and valve, a radiator fan, a system of channels in the cylinder block - a jacket, a temperature sensor, a thermostat, an expansion tank with a valve cover, a pump, and a radiator for the interior heater. Some vehicles also have an oil cooler and an exhaust gas recirculation radiator.
All these elements are very sensitive to contamination: they clog and “disconnect” small channels from the system, interfere with normal circulation, cause wear on the pump and thermostat, and cause antifreeze to leak onto the timing belt and other parts. Outwardly, this manifests itself in poor engine heating in winter and excessive heating in summer. There is probably no need to explain why overheating is dangerous: due to the high temperature, the motor parts begin to “drive”. In addition, CO contamination is indicated by poor operation of the radiator heater in winter, a dirty trace of antifreeze in the expansion tank, a dirty shade of the coolant itself, and its leaks.
The engine cooling system is sealed, so where do contaminants come from? How much dirt can there be in the cooling system of a working engine?
To begin with, any, even the highest quality antifreeze boils away over time and requires periodic dilution with distilled water. As a result of natural aging, scale, rust and sedimentation of coolant decomposition products occur. Since the system has numerous channels, pipes, recesses, tubes with a small section of a bizarre shape, these deposits do not come out during an antifreeze change, but remain inside, reducing the efficiency of the new coolant and the entire system as a whole.
In addition, engine oil and dirt can enter the system. This happens when the gaskets are worn out and do not fit tightly to the parts. The oil film formed on the surfaces of parts reduces thermal conductivity.
Let's elaborate a little on what we said above. All contaminants that may be in the engine cooling system can be divided into two types. Scale and rust are inorganic residues, while oil contamination and antifreeze decomposition products are organic.
They differ in composition and structure and are removed from the system using different chemical reactions. To combat inorganic contaminants, you must first dissolve them, then they will quietly drain out of the system along with the working flushing solution. A different approach is needed for organic matter: using surfactants to form a suspension of sediment, which will also be removed when draining the rinse. In other words, complete cleaning requires two fundamentally different approaches.
Hence the conclusion: an effective product must have both an emulsifying and dissolving effect. It is on this principle that the cooling system flushes of the LAVR line work. And that is why you should not rinse CO with ordinary or acidified water, as traditional craftsmen advise.
Let's look at the process of flushing the engine cooling system with a two-component composition LAVR “Complete cleaning of the cooling system” and using its example we will tell you how the product works.
After draining the old antifreeze, you need to vigorously shake preparation No. 1, which removes scale and rust, pour it into the expansion tank, and then add distilled water to the minimum mark. You need to warm up the engine to operating temperature, and then let it idle for 30 minutes.
The operating temperature is considered to be the opening temperature of the thermostat. To make sure that it has worked, you can wait until the temperature sensor on the dashboard shows 85-90 ° C, the fan starts working, or touch the main radiator pipe, which becomes warm when the thermostat opens.
After half an hour, we turn off the car, let it cool a little, loosening the cap of the expansion tank to relieve pressure in the system, and drain the liquid. Be careful the liquid may still be hot.
The algorithm of actions at the second stage is the same. Shake the jar with a composition that removes oil and antifreeze decomposition products. Fill it up, add distilled water, start it up, wait for the thermostat to open and set it for 30 minutes, and then drain it.
You can see in detail how a complete cleaning of the cooling system removes alkaline, oily contaminants and traces of antifreeze decomposition, how it removes rust and scale, and how the boiling point of old and new antifreeze differs in our video.
After the second stage of flushing using the “Complete cleaning of the cooling system”, you can summarize the intermediate results by comparing the condition of the drain plug before and after, as well as the old antifreeze, the fluid after the first stage of cleaning and the fluid after the second stage. The result will probably impress you, but we recommend performing the third step - flushing the system with distilled water.
We proceed according to the same plan as in the previous stages. Fill, warm up and leave to idle, but only for 15 minutes instead of 30. This last procedure can be repeated until the water comes out absolutely clean. Only after we have made sure that the cooling system is completely cleaned of scale, rust, traces of oil contaminants and antifreeze decomposition products, can we fill in fresh antifreeze.
A little advice - when filling the system, pour antifreeze slowly, in a thin stream. This way you minimize the likelihood of air locks forming in the system.
In conclusion, we add that flushing the cooling system is advisable every time you replace old antifreeze with a new one. Once every 3-5 years, it is advisable to allocate time for a procedure that will save more than one thousand rubles. Naturally, if you encounter a breakdown of the cylinder head gasket, flushing the system after replacing the gasket is mandatory. Also, do not forget about periodic external cleaning of the radiator from dust, traces of insects and other contaminants that reduce the heat transfer area.
And remember, the cleanliness of the engine cooling system is the key to engine longevity, preservation of vehicle power and a comfortable temperature in the cabin.

Flushing the engine cooling system with acid solutions
To remove scale, pour a weak solution of lactic acid into the system. As a rule - 6%. To do this, dissolve 1 kg of thirty-six percent lactic acid in 5 liters of water. The solution is poured into the system heated to 30-40°C. Almost immediately, a chemical reaction begins with the release of carbon dioxide. When the process is complete, everything is drained and the system is washed several times with water (see above) until the drained water is completely transparent.
The color of the liquid drained the first few times is far from normal
Sometimes whey is used as a lactic acid solution. After pouring it into the cooling system, you can drive the car for several hours, then drain everything and rinse it again several times with water. This procedure is easily tolerated by products of the domestic automobile industry, but with imported cars you need to be extremely careful, although some of their owners tried the serum and there were no negative consequences.
Using hydrochloric acid solution is a rather risky method, but it is also used quite often. The solution should be no more than 2%. The exposure time is until the process of gas evolution stops. Then drain everything and rinse it with water several times, finally adding liquids containing additives that form a protective film.
Another solution of acid is citric acid. The exact dosage is not given here, but the solution should be slightly acidic. The residence time of the solution in the system is also determined by the termination of the reaction. Thorough and repeated rinsing with water is also required.
The cooling system can be flushed using food grade citric acid
You can activate the process of cleaning the engine cooling system by starting the engine several times and letting it run for 5-10 minutes. This “activation” can be carried out several times. As a result, the cleansing will be more complete, but sometimes it happens that after such a procedure old “sores” appear or new ones open. On the one hand, this is not encouraging: it needs to be repaired, but on the other hand, you will be sure that in the near future you don’t have to worry about surprises from the engine cooling system: all the thin places were torn during washing and repaired. And there won’t necessarily be any unpleasant surprises. Often, after flushing without any complications, the system operates for more than one or two years without repair.
Some desperate car owners use even such an inappropriate, seemingly inappropriate, cleaning product as the “Duckling” toilet, and “active” one at that. And they are happy with the result: the system is clean, and after six months of operation there were no failures.
This is what the engine cooling system looks like after a good flush.
When using factory-made acid compositions, you must carefully read the instructions for use and strictly follow all instructions. Any deviation may result in malfunction and repair.
