How to flush the engine cooling system of a VAZ 2110

We flush the engine cooling system on a VAZ-2110 (review of products)

Of course, all VAZ-2110 drivers are well aware that only 23% of the thermal energy that is released in our combustion chamber is beneficial. That is, less than a quarter of all heat is converted into kinetic energy. The rest of the heat simply warms the engine and escapes into the atmosphere. And, of course, everyone understands that the faster this excess heat is removed from the engine, the more efficiently it will work . This is why our top ten have introduced a liquid cooling system.

When to flush

During operation, the radiator of the cooling system may become clogged. Moreover, it comes from the outside and from the inside. Today, manufacturers are trying to use higher quality materials, but even they do not protect against corrosion and scale.

If the antifreeze used is not replaced in time, it can also negatively affect the condition of the unit. A complex of such phenomena leads to the cooling system becoming dirty and in need of urgent cleaning.

It is not difficult to determine contamination of CO (cooling system) by a constantly overheating engine, regardless of weather conditions.

The frequency of flushing directly depends on operating conditions, engine condition, CO components used, etc.

Causes of pollution

Not every motorist understands the importance of such a procedure as flushing the cooling system:

Often, car enthusiasts limit themselves to adding or replacing antifreeze, but are very surprised when it turns black after a week
And the reason is simple - a dirty radiator
The engine cooling system is designed so that contaminants appear not only from the outside (such as dust, sand or insects)
But also from the inside (for example: scale, rust, motor oil, as well as sediment from the gradual decomposition of antifreeze)
A radiator clogged with dirt is no longer able to cope with its main task - cooling the engine; excessive contamination can lead to damage to the radiator and its replacement, and accordingly the cost of repairs will increase!

Engine cooling system flushing technology

To flush the engine cooling system in a VAZ-2110 with your own hands, you must follow the step-by-step instructions:

Open the filler cap of the expansion tank.
Place a container under the engine to drain the fluid.
Remove the bolt from the drain hole located on the cylindrical block.
The antifreeze that begins to pour out must fall exactly into the container, and not past it.
When the flow of antifreeze stops, unscrew the cap, which is located at the bottom of the radiator, and again pour the liquid into the container provided.
Put the plugs in place and pour distilled water inside, adding additives - a substance that will get rid of scale. Alternatively, you can add Hi-Gear product.
Now rinse the system thoroughly with water, mixing it with the cleaning component. If something does not come out by gravity, it is recommended to clean the surface by exposing it to water pressure. To do this, disassemble the pipeline, freeing the upper component and the base of the radiator from the pipe. As soon as clear liquid flows at the bottom of the radiator, the flow of water can be turned off. This completes the procedure.

Flushing the cooling system on a VAZ car - step-by-step instructions, several methods

Any driver wants his car to serve for a long time and trouble-free, so it is imperative to periodically flush the engine cooling system. How can this be done for the VAZ 2114 and other models (2110, 2107, 2112)? High-quality performance of this work can only be guaranteed if certain rules are observed.

Special cleaning products

There are special products designed for flushing the cooling system. They are quite expensive, but this is compensated by their high efficiency. Such products contain components that can cope with organic matter, grease, scale and rust. Special means are of the following types:

neutral. They do not contain aggressive substances, therefore they are mainly used for preventive purposes;
two-component. The most optimal and popular option for cleaning the cooling system. These products do their job perfectly;
acidic and alkaline. Most often they are found in diluted form, because they have the most aggressive effect.

How to wash the cooling system of a VAZ 2110 engine

Flushing the engine cooling system is divided into two types:

External – the outside is cleaned from dust, insects, and other dirt. Using water or car shampoo.
Internal – the inside is cleaned from accumulated scale, rust or any accumulated debris. Here the cleaning takes longer and requires force.

You can also flush the system in several ways:

On one's own.
Or in the workshop.

If you prefer to just pay money, then it will not be difficult to contact a specialist in any workshop where they will do everything for you. But how carefully and efficiently the master will do it is unknown. Therefore, if you do it yourself, you will not only save money, but also do the job efficiently, which not every master can guarantee.

Cleaning agents and methods

To flush the engine cooling system on a VAZ 2110, you can use different means. All of them have a certain effectiveness and nuances of application.

These tools used today include:

Distilled water;
Soda, vinegar, acids;
Specialized CO purification products.

Now let's figure out what is good or bad about each of the presented options.

Distilled water

Despite everything, distilled water continues to be actively used when flushing the engine cooling system. It is difficult to explain the reasons for its popularity, since this product is not highly effective.

Flushing the radiator with distilled water

The procedure for flushing CO using distilled water is as follows:

The old coolant is drained;
Distilled water is poured into the system;
The engine starts and sits with the engine running for 10, maximum 15 minutes;
The engine is turned off, after which the distilled water is drained;
The procedure is repeated until clean water comes out of the system.

The rating for the product is 1.5 out of 5.

Acid, soda, vinegar

This is a more stringent method of flushing the system when compared to using distilled water. However, the level of efficiency is significantly higher.

Cleaning OS with serum

To perform the flushing procedure, you will need:

Prepare an appropriate solution, which includes caustic soda, lactic acid and vinegar. This mixture is poured into the cooling system. Just do not add too much lactic acid, as this is an aggressive agent that destroys the rubber elements of the CO;
Then the system simply sits with the acidic liquid inside for no more than 8 hours. Ideally, it should stand for about 6 hours;
During this period of time, the engine periodically starts and runs for a short time;
When the specified time has elapsed, drain the acid solution, add distilled water and perform a procedure similar to the first washing method, where only water was used;
1-2 rinsing cycles with distilled water will be
enough to remove all remaining acid solution;
After this, all that remains is to fill in a new portion of antifreeze.

The rating for the product is 3.5 out of 5.

Specialized cleaning compounds

Go to any automotive chemical store, where you will find entire shelves with products designed for flushing engine cooling systems.

Get ready to spend a significant amount of money on them.

Specialized products are divided into four types:

Neutral;
Acidic;
Two-component;
Alkaline.

Alkaline and acidic are considered the most popular because they demonstrate a high level of efficiency, plus from a financial point of view they turned out to be quite attractive.
Two-component formulations include two main active elements - alkali and acid. They are offered in separate containers, the contents of which are poured into CO one at a time. This allows you to achieve excellent results and forget about a clogged cooling system and an overheated engine for a long time.
Neutral products do not contain aggressive components. They serve for prevention, since there is no real effectiveness for strong cleaning.

The rating for the product is 4.5 out of 5.

What's in it?

So, you purchased a car and don’t know what exactly is in the cooling system. If there is water or already used coolant there, this does not bode well for your engine.

Therefore, first of all, check whether there is any coolant in the engine at all, and what exactly it is. At the same time, make sure there are no leaks from the pipes or radiator.

It is not difficult to independently determine the type of fluid used by the old owner.

Antifreeze almost always has a blue or blue color.
Antifreeze is mainly available in red or green. Moreover, there are a huge variety of shades of red.
It is not difficult to distinguish water from blue or green liquid.
If the color of the coolant has a characteristic shade of rust, then this indicates the need for urgent replacement.

Green antifreeze

Mixing different coolants. Yes or no?

In some cases, the quality of the fluid is good enough that it is not necessary to replace it. Only the quantity is somewhat below the required level.

Let's say you have antifreeze filled, but you only have antifreeze on hand. What to do in such a situation? Many VAZ 2114 owners are interested in whether it is possible to mix different compounds.

Antifreeze or antifreeze

There is no consensus on this matter. Let us say for sure that a disaster will not occur from mixing, antifreeze and antifreeze will not react and will not explode the car. But we definitely cannot recommend combining two types of coolant in one tank. Follow the instructions in your car's manual, fill in what the factory recommends, and then you won't have any problems.

Antifreeze is simply a type of antifreeze developed in Soviet times for Zhiguli cars. This was done due to the low quality of the antifreeze offered at that time. Since then, antifreeze is the number one choice for VAZ.
