The working volume of coolant depends on the design of the cylinder block, the installed radiator and the pipeline. Replacing coolant is an important procedure that is performed in conjunction with flushing the cooling system.

Why is it necessary to change the coolant?

Antifreeze differs from distilled water in its boiling point and the rate at which heat is removed from the walls of the block. The liquid in the cooling system is periodically changed, since it is designed for a certain resource, after which the anti-corrosion and functional properties of the coolant are lost.

Check the coolant level in the expansion tank. The liquid gradually boils away and needs to be replenished periodically.

Replacement is also carried out when the cooling system is contaminated. The radiator and pipes gradually become clogged, which can lead to a blockage. The engine may overheat and seize due to a clogged cooling system:

corrosive particles and dust;
salt deposits on the internal channels of the radiator and block;
blockage of pipes with oxidative sediment.

The expansion tank of the engine cooling system is used to control the coolant level. When adding fluid in a timely manner, pay attention to the visual condition of the antifreeze. Signs for replacement: change in color, consistency, appearance of cloudy sediment and solid particles.

When to change the coolant

Replacement is carried out after passing a certain mileage - 40-50 thousand km. When undergoing maintenance, they check the coolant level in the tank and conduct a visual inspection for impurities (read what it is). Cloudiness and a change in shade indicate foreign inclusions in the coolant or a change in the properties of the composition.

The need to clean the cooling system and replace the coolant is indicated by a number of signs that are reflected in changes in the operation of the car:

frequent overheating and boiling of the coolant;
constant operation of the internal combustion engine at a critical temperature (the water sensor shows maximum readings);
interruptions when starting a warm engine;
change in rheostat response and problems with pump operation.

If such situations arise or the color of the coolant changes to a reddish color, the cooling system must be immediately cleaned and the coolant replaced.

After traveling a certain mileage or identifying problems in the cooling system, it is necessary to undergo vehicle maintenance. You can visit a service station or perform the process yourself. How to replace coolant?

Replacement is carried out on a cooled engine and using protective equipment.

To carry out the procedure you will need:

set of tools - screwdrivers and wrenches,
containers for draining waste,
rubberized gloves,
flushing additives,
new coolant - distilled water, antifreeze or other antifreeze.

The car is placed on an inclined platform or overpass - in this position the liquid drains better from the system.

The procedure is carried out as follows.

Install a container to drain the old coolant.
Remove the radiator pipe.
Unscrew the valve on the flow control tank. After the system is completely emptied, the remains are drained from the cylinder block.
Having removed the dust shield, open the valve on the interior heater apparatus (to bleed the pipeline).

After draining all the used antifreeze, proceed to preparing the flushing composition.

Radiator flushing

To clean technological channels from oxidative sediment and rust, special chemical additives or folk cleaning products are used. You can remove salt deposits using citric acid, soda and even cola.

To prepare the compositions, carefully read the instructions. Additives are mixed in certain proportions, and the period and method of washing differs in the time of exposure of the reagent in the system.

Washing steps and sequence:

prepare a solution,
fill the system and close the drain holes,
start and warm up the engine according to the mode specified in the additive instructions.

After working for some time (up to 30 minutes or driving 10 - 15 km), wait until the engine cools down.

For more detailed information on how to kick out, read the article by our specialist.

You can read about the features of inspection and repair in the material of our author.

Adding fresh antifreeze

Before filling in new coolant, the pipeline elements are checked for integrity (cracks and wear). Some rubber hoses, clamps and gaskets will need to be replaced.

Do not forget about the possibility of air pockets - fill with CO until the air is completely bled out.

The sequence of stages is as follows.

The radiator is washed with water to remove old additives and remaining silt inclusions.
Connect the car's heating system.
Add a couple of liters of distilled water, and then gradually add antifreeze.
Filling is carried out until liquid exits the technical channels.

After completing the work, before starting the engine, check the filling level of the system and tightly close the filler tank cap.

At the final stage, fix the pipes with clamps and start the engine. At increased speeds (about 3 minutes), complete circulation of antifreeze occurs in the system. Subsequent monitoring is carried out after the engine has cooled down, when the pressure in the system drops. If necessary, add antifreeze to the expansion tank to the average level.

Coolants on the market

Regular replacement of antifreeze is important for the engine cooling system to operate without problems. Let's talk about how to properly replace the coolant in a car (+ video) and how often it needs to be changed.

Plain water is best suited for engine cooling. It has excellent heat capacity. But its disadvantage is that it freezes at subzero temperatures and leads to corrosion of parts of the cooling system - it clogs the radiator and reduces service life. Therefore, manufacturers use antifreeze (the same as antifreeze).

When should you change?

It is recommended to change the coolant every 2-3 years to prevent corrosion. In fact, the actual service life is determined by the car manufacturer. For example, Volkswagen and GM give a lifetime period for replacing antifreeze in a car, Ford - ten years or 240,000 km, Mercedes-Benz - five years, AvtoVAZ - 75,000 km. BMW and Mitsubishi recommend changing every 4 years, Daimler - every fifteen years. Mazda and Renault say that coolant changes are not necessary for the entire life of the car.

Why is it possible not to change antifreeze for a long time? Manufacturers have released a new generation of antifreezes with a formula that allows you to increase replacement periods to 200,000 km. The duration depends on the content of anti-corrosion additives. As long as they are present, everything is fine. Once the amount of anti-corrosion substances is reduced, the engine and radiator are subject to corrosion. It is especially dangerous for motors with aluminum parts.

If the time has come to replace the antifreeze, then ideally we replace it with the original one that was filled in at the factory. But how do you find out and is it possible to buy a similar one in a store? When choosing a coolant, follow the car manufacturer's recommendations specified in the service book. If the type of recommended coolant cannot be determined, then you should buy antifreeze marked G12, as the most universal.

How do you know when it's time to change? You need to look under the hood of the car and check the condition of the fluid in the expansion tank of the cooling system (you can find out where it is located in the instructions). It should be clean without dirt or other debris. It's like comparing clean water from a spring and rusty water from a tap. If in doubt, it is better to change it.

Another question is whether the cooling system needs to be flushed? When replacing coolant, flushing is mandatory, especially if the drained antifreeze contains oil, dirt and other contaminants, or you don’t know what was filled in earlier. If, when replacing, the old fluid does not have any contaminants, and you fill it with exactly the same one that was previously, then flushing is not necessary.

How to replace it yourself?

Antifreeze is changed on a cold engine. Changing while hot is dangerous, because... its temperature is about 90-100 degrees. Find the radiator/tank cap and remove it, then find the radiator drain plug and open it, after placing a large bucket under it. Drain the coolant. Then inspect the cooling system hoses for cracks and breaks. Change them if necessary.

Before adding antifreeze, flush the system to remove rust and deposits that water cannot remove. For washing, special auto chemical products are used. It is necessary to fill them into the radiator and add distilled or filtered water to the tank to the brim. Close the lids. The next step is to turn on the engine and wait until it reaches operating temperature. Then “turn off” the engine, let it cool, and drain the liquid.

Afterwards, you need to pour water into the system, close the lids and turn on the engine again for 15 minutes. Let it cool and drain the water. After this, fill in new antifreeze. Next, you need to “turn on” the engine and heating in the cabin to “maximum” so that the coolant is evenly distributed throughout the system to remove air bubbles. After a few days, be sure to check the antifreeze level in the system and add it to the correct level if necessary.

During operation, the coolant in the engine goes through multiple heating and cooling cycles. As a result, he ages and loses his characteristics. Timely replacement of antifreeze on the Polo Sedan is one of the necessary procedures when carrying out vehicle maintenance.

Timing for coolant replacement

In addition to a planned shift, an emergency shift may be required due to a number of reasons:

Premature aging of the liquid. For example, due to exhaust gases entering the system through a damaged gasket. Externally, this can be determined by a change in the color of the refrigerant (discoloration or blackening) or the appearance of foam and deposits in the expansion tank.
Liquid leakage from the system and the impossibility of topping up the exact brand of antifreeze that is already filled.
Deterioration in cooling properties, especially noticeable in hot weather.
Breakdown of the gasket between the head and the block, as a result of which mutual and engine oil begins to flow.

What coolant to fill

Until 2012, Volkswagen cars were filled with red antifreeze that complied with the G12, G12+ and G12++ standards (article number N 052 774 G0). On later cars of the concern, yellow liquid of class G13 (original product article number N 052 774 J0) began to be used, which has higher characteristics.

This change did not affect cars from the Kaluga plant, and all Russian-assembled Polo Sedan are filled with G12++ standard fluid. When first filling Polo Sedan cars, Sintec brand antifreeze is used, diluted with water in equal proportions. Since the original G12 fluid is no longer available for sale, most car owners fill the system with ready-made G12++ or Sintec Antifreeze Premium G12+ when replacing it. In addition, it is possible to use a more modern version of the G13 refrigerant, although the cooling system is not designed to use this antifreeze. The article number of the original concentrate 1.5 liters of liquid of this type is G013A8JM1, the finished coolant is GA13774M2.

Sintec Antifreeze Premium

Level control and required volume

When replacing antifreeze, it is necessary to take into account the volume of the cooling system, since pouring excessive amounts of liquid is not recommended. The system of cars manufactured before November 2015, as well as later versions with a new engine of 110 and 90 horsepower, contains 4.52 liters of fluid. On cars with 1.4 liter 125 l/s engines, the system capacity is larger; 7.03 liters of coolant are poured into it.

To check how much antifreeze is in the system, cool the engine, open the hood and find the spherical reservoir, which is located in the engine compartment on the right wheel arch. On the side surface of the tank there are marks for the minimum and maximum liquid levels. Under normal operating conditions, the amount of refrigerant should be between these marks. If the level drops, it is necessary to restore it and check the tightness of the system. You can only top up the antifreeze that was filled in earlier.

The author of the video, Konstantin Sabirov, will tell you how to add refrigerant to a Volkswagen Polo.

How to replace coolant with your own hands

Any owner of this car can independently change the antifreeze on the Polo Sedan if he has minimal experience in car repair and maintenance. Before starting the replacement, you must purchase ready-made antifreeze or concentrate. The second option is diluted with distilled water in the same proportion, i.e. to obtain 4.52 liters of finished liquid you will need 2.26 liters of concentrate and water. When replacing the refrigerant, flush the system with distilled water to completely remove any remaining antifreeze.

Tools

To complete the work you will need:

Torx T-25 head, if there is a standard plastic protection under the engine;
a fairly wide container for draining old liquid with a volume of at least 6-7 liters;
pliers or pliers for removing spring clamps;
distilled water in the amount of 10-15 liters;
liquid concentrate or ready-made antifreeze in the required volume;
empty container up to 5 liters for preparing new refrigerant.

Step-by-step instruction

It is important to consider that it is preferable to drain the used fluid from a cold engine, since there is no risk of burns.

To replace the coolant on Volkswagen Polo Sedan 2013 and other model years, you need to perform the following steps:

Place the car above the inspection hole or lift it on a lift. There is no need to open the expansion tank cap.
Remove the standard or additional protection of the engine compartment.
Find the lower radiator hose secured with a spring clamp. Carefully separate the clamp by bringing its ends together, remove the pipe and direct its end into a previously prepared container.
Remove the cap from the expansion tank.
Wait until the liquid is completely drained and install the pipe in its original place.
To flush the system, pour 4.5 liters of distilled water through the neck of the expansion tank and start the engine for 2-3 minutes. In this case, it is not necessary to wear a collar.
Remove the lower pipe and drain the water. Carry out the flushing procedure several times until colorless liquid begins to flow from the cooling system.
After this, you can fill the system with fresh antifreeze to the top mark in the expansion tank. It is important not to forget to put the clamp on the lower pipe. When installing the clamp, it must be placed in the area marked with a white line on the pipe.
Start the engine and wait a few minutes. To remove air bubbles in the system, it is necessary to briefly open the reservoir cap while the engine is running. If the fluid level in the tank drops, top it up.
Warm up the engine until the cooling system fan operates. While the engine is warming up, it is necessary to monitor its temperature using the red indicator light on the instrument cluster. When it turns on, the motor must be stopped.
Turn off the unit and allow it to cool completely. After this, you need to check the fluid level again and add as necessary.
Check for leaks in the lower radiator pipe.
Reinstall the protection.

Price issue

The cost of replacing antifreeze on your Polo Sedan yourself will include the price of only two components - refrigerant costing from 690 to 720 rubles. for a container of 5 liters and distilled water - about 150 rubles. for three canisters with a capacity of 5 liters each. When filling with G13 fluid, the cost will be 1,500 rubles. for the finished liquid and about 1 thousand rubles. for concentrate. To this amount you must also add the price of distilled water. The total cost of replacing the refrigerant with your own hands will not exceed 2 thousand rubles.

Changing the coolant at service centers will cost the car owner 3-4 thousand rubles.

One of the common causes of car breakdowns while driving is precisely a malfunction in the vehicle’s cooling system (and, consequently, in the functioning of the engine). Nevertheless, an impressive number of car owners continue to neglect the significance of this problem.

The proposed review article will help analyze the role of antifreeze (or coolant) in the full operation of the car; how to choose the right car product and replace it yourself at home (taking into account why such a need arose).

Why do you need antifreeze in a car?

The key purpose of coolant (or coolant) is to reduce the level of thermal impact on components and other parts of an internal combustion engine installed in a vehicle during operation. Moving in a closed circle with the help of a centrifugal pump, directly touching the walls of the cylindrical engine block (where the temperature of the combustible fuel reaches the maximum level of degrees Celsius), the antifreeze, cooling in the radiator, through a special cavity (the “cooling jacket” of the power design) takes up heat and removes its excess from the engine cylinder system. The expansion tank in the cooling mechanism is provided for the “coolant” reserve.

Did you know? The manufacturer adopted the word “land” in the name of the Land Cruiser Toyota from another car manufacturing company - Land Rover, and until 1954 this model was called Toyota BJ. Antifreeze for such SUVs is selected depending on the modification.

In order for the engine to cool down faster, two types of coolant are used: distilled water and antifreeze. Water, which must be purified, is the cheapest and non-toxic method with the highest heat capacity (the amount of heat required to heat a certain body) and a good ability to cool. Antifreeze is an element with a complex chemical structure, which is characterized by a high boiling point and immunity to critically low ambient temperatures (from minus 40 to minus 70).

In the engine cooling mechanism of current cars, water is not used on a regular basis due to its low practicality in the cold season. We are talking about freezing already at zero temperature, an increase in volume by 10%, followed by transformation into a solid state of aggregation. Thus, under such circumstances, water can no longer perform the main function - limiting the motor from heat. Ice crystals formed in the cooling mechanism of a vehicle have every chance of “causing harm” to engine components and parts, destroying cylindrical blocks and heads.

The composition of antifreeze liquid includes 2 basic components: water and polyhydric alcohols (ethylene or propylene glycol), which have the specific ability to expand their volume when heated (and this is one of the most important functions of the refrigerant for an automobile cooling system).

Propylene glycol has a lower density and higher viscosity than ethylene glycol. Thus, the former has less toxicity. Unfortunately, the latter quality, when exposed to external subzero temperatures on the internal combustion unit, provokes a drop in the rate of fluid circulation through the car’s cooling mechanism, negatively affecting the efficiency of its main functions.
In the structure of antifreeze, in addition to water and polyhydric alcohols, as a rule, there are various additives that improve the performance properties of the product: suppressing the start of corrosion in the form of rust on metal surfaces, boiling when the maximum temperature level is reached, destruction of rubber elements, and the creation of steam condensate.

Important!The quality, service life and cost of the coolant depend on which additives have been added.

How often is replacement necessary?

Most often, the need to replace antifreeze in a car depends on the quality and type of liquid. Its factory service life is also important. The procedure for changing the refrigerant in the cooling system is performed in three cases:

As planned

The timing of planned replacement depends on the following indicators:

type of antifreeze;
recommendations in documents on the use of a specific car model;
working properties of the coolant after expiration of its usefulness (on average, after 4-5 years it loses its ability to resist the formation of rust, can boil at relatively low internal temperatures, and removes heat from structures and elements of aggregate installations worse).

Premature or ahead of schedule

It is used when there is a structural failure of the engine or a leak in the cooling system, and therefore when gases from the exhaust pipe or outside air enter the antifreeze. These deviations can be noticed when the frequency of switching on the radiator fan has increased, and at a temperature of minus 15 Celsius, sediment or jelly-like deposits are noticeable on the walls and bottom of the expansion tank.

Due to an emergency

Antifreeze is replaced if the cooling system hose bursts and the liquid decreases in volume due to leakage. In an emergency, the driver has to bring the amount of fluid in the system to the original level, and, as practice shows, this is most often done using tap water. However, compared to purified distilled water, the latter contains a considerable amount of salt compounds, which, when interacting with coolant additives, activate the occurrence of corrosion processes and the formation of sediment.
The flow of refrigerant through the system is hampered, and the efficiency of heat removal from the engine components is reduced. Consequently, the latter overheats. That is why, at the first opportunity, it will be necessary to completely replace the antifreeze, first rinsing the mechanism with distilled water.

Did you know? According to Mercedes-Benz, the record for mileage on cars of its brand was broken by Greek taxi driver Gregorios Sachinides. Over the 23 years of using his 1976 Model 240 D, he drove it 4.6 million km (that's 200 thousand km/year, about 20 thousand km/month and approximately 700 km/day). In 2004, the owner donated his car to the Mercedes-Benz Museum, located in Stuttgart (Germany), and received a new one in return.

The main procedures for caring for the cooling system, preventing premature and emergency replacement of antifreeze, are:

timely cleaning of the cooling mechanism, as well as replacement of the refrigerant;
regular monitoring of the level of cooling liquid in the tank;
periodically inspect the cooling system elements for malfunctions: hoses (they should not be swollen), belts (do not allow excessive wear and damage to the latter) and the radiator (it should not leak).

How to choose the right one when purchasing

If you are going to purchase high-quality refrigerant for the cooling system of your car, then you must first of all pay attention to the recommendations for operating your car from the manufacturer. To do this, you should carefully study the vehicle documents: they must indicate which antifreezes can be directly used to cool the engine of your car.
If it is impossible to find a similar factory-made fluid in a regular car store, contact an official dealer of your car brand and order the same coolant or ask for help in choosing an analogue. The amount of antifreeze is also indicated in the operating documentation (on average this is 6-8 liters of liquid).

Important!If, during the process of replacing the coolant, you drained the remaining coolant and found impurities and characteristic sediment in it, you must first clean the engine cooling mechanism using detergents containing organic acids, and then use distilled water.

A mandatory point when purchasing antifreeze (like any other product) is to carefully study the date of manufacture, expiration date and storage conditions. Under no circumstances take liquid that leaks through the lid when the container is turned upside down: failure to seal the packaging during storage may affect its quality. There should be no small particles or sediment at the bottom of the bottle or canister. When shaking a package with high-quality coolant, the foam resulting from this process should disappear within ten seconds.

Antifreeze for cars can be of 4 types, which differ in functional additives:

Did you know?Ferruccio Lamborghini started his business by producing not cars, but tractors. Having owned a Ferrari 250 GT, he often complained about its supposed “factory” clutch problems. When Ferruccio turned to Enzo Ferrari with a remark about this deviation in the operation of the mechanism, the latter pointed out to Lamborghini his ignorance of the process of manufacturing sports cars (in contrast to Ferruccio’s direct specialty - the production of tractors). The future industrialist and businessman decided to completely disassemble the car and improve all its components. And so began Lamborghini's automotive production career.

How to replace antifreeze in a car with your own hands

Replacing factory-filled coolant is not difficult, so you can perform this procedure yourself. It is recommended to wear gloves before carrying out this process, since antifreezes themselves are toxic and can cause severe intoxication if they come into contact with exposed skin areas.

The method for replacing antifreeze in a car is as follows:

Video: How to properly replace antifreeze Thus, we can conclude that antifreeze plays an important role in the quality functioning of a car’s internal combustion engine. Monitoring the integrity of the elements that make up the cooling system, timely and correct replacement of the refrigerant will protect you from unexpected unpleasant situations on the road.

Important! You cannot mix old and new coolant because the former has a shorter shelf life. And here’s why: the different components that make up them can enter into a chemical reaction, which can negatively affect the performance properties of antifreeze.

Replacing old antifreeze with new one at home is not that difficult. The main thing is to do everything according to the instructions, do not forget to drain the old fluid and only after the system has been completely cleaned, fill in the new one.

Constant renewal of cooling water is simply necessary in a car for its normal operation, every driver knows about this. But through How many km and time do you need to change the antifreeze? We will try to give detailed answers to this and other questions. To avoid engine overheating, all vehicle manufacturers advise changing the fluid every 45 thousand km. 100% mechanics say that it is best to change it once a year to avoid corrosion on the walls of the radiator. But this is rather outdated advice, because once a year new modern products appear on the market, which are enough for a mileage of 100 to 250 thousand km. This means that the antifreeze change interval will be even longer. But manufacturers claim that the newest coolant should be poured exclusively into a clean system so that it does not mix with the remnants of the previous one, otherwise its physical and chemical characteristics will decrease. That’s why replacing greenish antifreeze with blue, even if it’s the same brand, is not recommended.

HOW OFTEN DO YOU NEED TO CHANGE ANTIFREEZE?

PARTNER AIR: Subscribe to the channel.

So, we have already figured out when it’s time to change antifreeze to new antifreeze. Let's take a closer look at the replacement process itself. This should be done when the engine is cold, but it is dangerous to carry out such a procedure on a hot engine. Remove the radiator cap, then find the radiator drain cap, open it and place a container under it. Drain the residue and then inspect the cooling system hoses to ensure there are no breaks or cracks. If necessary, change the hoses. Next, rinse the system to remove all deposits, rust and grease that cannot be easily removed with ordinary water. To do this, use a special cleaning agent. When pouring it into the radiator, add demineralized and deionized water to the very edges and close the lid.

The next step is to turn on the heater and engine and wait until they warm up. After that, turn them off and let them cool, and then remove the cap from the radiator and drain all the mixture from it, then pour regular water into the system, close the radiator cap again and turn on the engine for 15 minutes. Let it cool, drain the water from the cooling system, and only then can you add a new product.
