Means for flushing the engine cooling system. Than to wash and how it to make?

Liquid engine cooling system is needed formaintaining the normal operating temperature of the power unit during its operation. The motor is cooled by forcibly diverting excessive temperature indicators from its component parts and assemblies. This ensures optimal thermal conditions. In the absence of normal cooling, the engine overheats and can receive both individual damage and fail completely. Therefore, it is important to monitor the good condition of the cooling system and to take timely diagnostic measures and troubleshoot various problems.

Scaling inside

One of the reasons a power unit canOverheating is a clogging of the system with various deposits and scale, which disrupt the normal circulation of antifreeze. A variety of technological methods and means for flushing the engine cooling system reduces the risk of this problem.

Often, the radiator, the heater of the passenger compartment, a variety of pipes and the blockter case are often affected by scale.

During long-term car operation, within two years, salt deposits, rust, scale and decomposition products of the applied antifreeze are formed on the internal walls of the system elements.

When to rinse?

Before rinsing SOD, it is important to determinethe degree of contamination and ensure the need for this process. It is recommended to clean the SOD motor approximately once every two years or when the operating temperature of the power plant exceeds the optimum value.

No matter what quality antifreeze orantifreeze is used as a coolant, anyway after a certain period of time, they lose their physical and chemical characteristics - the liquid breaks down into separate groups of chemical components.

In this case, one group is deposited on the walls of the cavities of the system in the form of plaque, and other components are transferred to the sediment, thereby partially blocking the channels.

The presence of scale prevents the normal processheat transfer, and various jams of garbage do not allow the liquid to fully circulate through the system. As a result, the efficiency is significantly reduced. So to say, folk and special means for flushing the engine cooling system perfectly cope with various sedimentary formations. They are often used to restore the health of all elements of the system.

Engine flush methods

Depending on the degree of contamination, there are several options for cleaning the motor:

• With the use of distilled water, boiled and with the addition of acid in it.
• Using a special fluid for flushing the engine cooling system.

Properly chosen means and method affects the quality of cleaning and removal of sediment and clogging from SOD.

Determining the degree of clogging

The degree of clogging can be determined by the quality of the coolant. To do this, it is drained from the engine.

When antifreeze has a dark brown color, rust elements and grease stains - the engine has a strong contamination.

In this situation, in order for the cleaning to be positive, you need to use water with added acids or specialized industrial means for flushing the engine cooling system.

If the drained cooling liquid has a lightshade, without obvious signs of various precipitations and turbidity, in this case, it is enough just to wash the system with boiled water or distilled.

Washing with water

It is worth noting that to make the process of replacing the coolantand flushing the cooling system is necessary on a cold engine, using personal protective equipment. The first step is to remove the cap from the coolant expansion tank. Then unscrew the bolts draining the fluid from the system, which are in the engine crankcase and in the radiator and wait until the antifreeze is completely merged. Twist the bolts back and pour the usual boiled or distilled water into the car. We start the engine and leave it to work at low revs for fifteen to twenty minutes.

After that, the water must be drained. If it is dirty, the procedure should be repeated until it is clean. Only then can a new cooling agent be poured into the engine.

Acid removal

When in the waste liquid there are smallelements of scale, then in this case for washing it is advisable to use more effective means, namely water with the addition of acids to it. As an additive, you can use the usual vinegar and lemon, milk or caustic soda.

Washing the engine cooling system with citric acid

The effectiveness of this method depends onthe percentage of acid in water, as well as the presence of a certain engine temperature. Its optimal effect on sediments occurs at temperatures from sixty to ninety degrees.

According to the recommendations, the washing solution is made at the rate of one hundred grams of acid per five liters of water. Depending on the volume of coolant in the system, the amount of acid varies in direct proportion to water.

Washing method is the same as when usingordinary water, but with one nuance - this liquid for flushing the engine cooling system must have a high temperature. Therefore, after it was poured into the engine, you need to warm it up to operating temperature.

Washing in this way is carried out for half an hour, and if necessary, repeat the process. After the system is necessary to rinse with distilled water.

Use vinegar

When used as a flushThe material of vinegar should also be proportioned during the preparation of the solution. Usually it is recommended to add half a liter of nine percent vinegar to ten liters of water. Next, the mixture is poured into the cooling system, warm up the engine to the operating temperature and jam it. After that, you need to put the car on a simple for about eight - ten hours. After draining the washing, we determine the result, and if necessary, repeat the operation. At the end of the work, the engine should be washed with distilled water.

Caustic soda

This type of flushing agentThe engine is mainly used for cleaning radiators and stoves. It should be noted that caustic can be used only on parts made of copper or brass, aluminum radiators should not be washed with caustic soda. Also this washing material is not used as a cleaning of the cooling jacket of the unit.

The caustic solution is made as follows - fifty grams of caustic soda is added to one liter of distilled water. Before flushing, the radiator must be removed from the vehicle.

Milk serum

Serum is an excellent flushing system.engine cooling. Feedback from experienced drivers is a direct confirmation of this fact. Due to its chemical properties and components, it easily dissolves petrified scale and sediment, while at the same time does not expose various rubber components of CO to aggressive action.

Before use, strain it through a fine sieve.Then it is poured into the engine and serum is used as the main cooling fluid of approximately one thousand kilometers of the vehicle. With this method of washing should periodically check the state of the serum and monitor the operating temperature of the power unit.

Flushing the engine cooling system Coca-Cola

В связи с тем, что в состав этого напитка входит orthophosphoric acid, cola is excellent as a wash material. But he has his drawbacks. First, it is the presence of a large amount of sugar in the drink, which, in turn, can remain in the system and re-clog it. Therefore, after using cola, it is necessary to re-wash the SOD with water.

The second drawback is a large concentration.carbon dioxide, which is released when this "flush" is heated. To prevent damage to system components when using cola, it is recommended to remove gases from it.

Chemicals

Often motorists face a problem:What is the rinse WITH - national methods or is it still using certified means? As a rule, all sorts of washing "substitutes" may not give the desired result, especially when it comes to used cars. In such cases, it is desirable to use special factory washes, the so-called seven minutes. This name they received due to the short time of the operation of descaling. The composition of chemical cleaners includes components that do an excellent job with their task, thereby not harming the power plant.

One of these washes refers to the meanstrademark "High-Gear". Flushing the engine cooling system Hi-Gear will give the desired result in just a few minutes. So, with the use of this tool, the normal circulation of cooling fluid is restored through the pipes and the radiator. Eliminates the possibility of overheating of the motor at the time of idle traffic. Prevents the rubber parts of the system from being destroyed due to the highly active components of the preparation.

Flushing does not include aggressive acids, butAfter using it, you do not need to re-flush the POD. In addition, one package may be enough for several procedures. This drug is added to the water that is poured into the engine, and in just seven minutes the engine cooling system is flushed. The price of washing material is quite affordable and amounts to about one hundred rubles. Moreover, the cleaning itself can be done independently - at no extra cost.

Regardless of the model and make of the machine, the process of removing deposits and scale in SOD is almost the same.

Flushing the engine cooling system VAZcarried out the same way as on imported cars, with only one difference: due to the simplicity of the design of the power unit, the process is less time consuming and costly.

Summarize

Based on the above, it can be noted thatclearing the cooling system from clogs is not that difficult. The main thing with this is to observe safety precautions, to use cleaning agents wisely, the same applies to the correct preparation of solutions. Using liquid for flushing the engine cooling system of the factory, it is important to familiarize yourself with the instructions for its use and purpose.

So, we found out what means for flushing the engine cooling system is better suited.
