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

The liquid cooling system of the engine is needed to maintain the normal operating temperature of the power unit during operation. The motor is cooled by forcibly removing excess temperature values from its component parts and assemblies. This ensures an optimal thermal regime. In the absence of normal cooling, the engine overheats and can get both separate damages, and completely fail. Therefore, it is important to monitor the serviceable state of the cooling system and promptly conduct diagnostic activities and troubleshoot various problems.

Scaling inside

One of the reasons, when the power unit can overheat is the clogging of the system with various deposits and scale, in which the normal circulation of the antifreeze is disturbed. A variety of technological methods and means for flushing the engine cooling system reduce the risk of this problem.

Often, the influence of scale is affected by the radiator, the heater of the cabin heater, various nozzles and the block-crankcase itself. When the vehicle is operated for a long time, within two years, salt deposits, rust, scale and decomposition products of the antifreeze antifreeze are formed on the internal walls of the system elements.

When to wash?

Before rinsing SOD, it is important to determine the degree of contamination and make sure that this process is necessary. It is recommended to clean the SOD motor approximately every two years or when the operating temperature regime of the power plant exceeds the optimum value.

Regardless of the quality of antifreeze or antifreeze used as coolant, after a certain period of time they lose their physical and chemical characteristics - the liquid breaks down into separate groups of chemical constituents. In this case, one group settles on the walls of the cavities of the system in the form of plaque, and other components become sediment, thereby partially clogging the channels.

The presence of scale prevents the normal process of heat transfer, and various plugs from the debris do not allow the fluid to 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 handle various sedimentary formations. They are often used to restore the health of all elements of the system.

Methods of washing the engine

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

• Using distilled water, boiled and with the addition of acid.
• Using a special fluid to flush the engine cooling system.

Correctly chosen means and method affects the quality of cleaning and removal of sediment and clog from the ODS.

Determination of 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 the antifreeze has a dark brown color, rust elements and grease stains - the engine has a severe pollution.

In this situation, in order for the purification to be of a positive nature, it is necessary to use water with the addition of acids or specialized industrial means for flushing the engine cooling system.

If the merged cooling liquid has a light tint, without obvious signs of various precipitations and turbidity, then in this case it is sufficient to rinse the system with boiled water or distilled water.

Washing with water

It is worth noting that the process of replacing the coolant and flushing the cooling system is necessary on a cold engine, using personal protective equipment. The first step is to remove the cover from the coolant expansion tank. Then unscrew the drain bolts from the system, which are in the crankcase of the engine and in the radiator and wait until the antifreeze completely merges. We tighten bolts back and fill in the machine usual boiled or distilled water. We start the engine and leave it to run at low speed for fifteen to twenty minutes. After that, the water must be drained. If it is dirty - the procedure should be repeated until the time when it is not clean. Only then you can pour a new cooling agent into the engine.

Removal of clog with the use of acids

When small scale elements are present in the waste liquid, then in this case it is expedient to use a more effective means for washing, namely water with the addition of acids to it. As an additive, you can use ordinary vinegar and lemon, lactic or caustic.

Flushing the engine cooling system with citric acid

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

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

The washing method is the same as with conventional water, but with one nuance - this liquid for washing the engine cooling system must have a high temperature. Therefore, after it was poured into the engine, it must be heated to operating temperature. Flushing in this way is carried out for half an hour, and if necessary repeat the process. After the system must be washed with ordinary distilled water.

Using Vinegar

When using table vinegar as a washing material, you should also observe the proportions during the preparation of the solution. It is usually recommended to add ten liters of water to a half-liter of nine percent vinegar. Next, the prepared mixture is poured into the cooling system, the engine is warmed up to the operating temperature and jammed. After that it is necessary to put the car on a simple one for about eight to ten hours. After draining the rinse, determine the result, and if necessary, repeat the operation. At the end of the work, the engine must be rinsed with distilled water.

Caustic soda

This type of means for flushing the engine cooling system 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 washed with caustic soda is not recommended. Also, this cleaning material is not used as a cleaning for the cooling jacket of the unit.

The caustic solution is made as follows - one liter of distilled water is added with 50 grams of caustic soda. Before rinsing, the radiator must be dismantled from the vehicle.

Milk serum

Serum is an excellent flushing of the engine cooling system. The testimonials of experienced drivers are a direct confirmation of this fact. Due to its chemical properties and components, it easily dissolves the petrified scum and sediment, while at the same time does not exaggerate the various rubber components of CO.

Before use, it is filtered through a fine sieve. Then pour into the motor and use the serum as the main cooling liquid about one thousand kilometers of the vehicle's run. With this method of washing should periodically check the status of the serum and monitor the operating temperature of the power unit.

Flushing the engine cooling system with Coca-Cola

Due to the fact that this drink contains orthophosphoric acid, the cola is excellent as a washing material. But he also has his shortcomings. First, it is the presence in the drink of a large amount of sugar, which, in turn, can remain in the system and repeatedly clog it. Therefore, after using the cola, it is necessary to re-wash the SOD with water. The second drawback is the high concentration of carbon dioxide that is released when this "wash" is heated. To prevent damage to the constituent parts of the system when using cola, it is recommended to remove gases from it.

Chemicals

Often, motorists are faced with a problem: what to wash CO - by popular means or even applying certified means? As a rule, all sorts of washing "substitutes" can not give the desired result, especially when it comes to second-hand cars. In such cases, it is advisable to use special factory flushes, the so-called seven minutes. This name they received due to a short time of the operation of descaling. The composition of chemical cleaners includes components that perfectly cope with their task, thereby not harming the power plant.

One of these flushes includes the means of the trade mark "High-Gyr". Flushing the engine cooling system Hi-Gear will give the desired result and in just a few minutes. So, with the use of this tool, the normal circulation of the cooling liquid through the nozzles and the radiator is restored. Excludes the possibility of overheating of the motor when idle in traffic. Prevents from the destruction of rubber parts of the system due to the highly active components of the drug.

Washing does not have aggressive acids, and after its use it is not necessary to rinse SOD again. In addition, one package may be enough for several procedures. This product is added to the water that is poured into the engine, and only for seven minutes the engine cooling system is flushed. The price of the washing material is quite affordable and is about one hundred rubles. And the cleaning itself can be done independently - without extra costs.

Regardless of the model and brand of the machine, the process of removing deposits and scale in SOD is practically the same. Washing of the VAZ engine cooling system is carried out in the same way as in imported cars, with only one difference: in view of the simplicity of the power unit design, the process is less time-consuming and expensive.

Summarize

Proceeding from the above, it can be noted that it is not so difficult to clean the cooling system from clogging. The main thing at the same time is to observe safety techniques, use cleansing wisely with the mind, the same applies to the correct preparation of solutions. Using a liquid for flushing the cooling system of a factory-made engine, it is important to become familiar with the instruction for its use and purpose.

So, we found out what means for flushing the engine cooling system would be better.
