How to replace the cooling fluid on Skoda Octavia A5 correctly? Why change coolant liquid

Taking into account the recommendations of the manufacturer, the replacement of antifreeze in the machines Skoda Octavia is produced, with periodicity of every 6 years, or after 90,000 km (if you take into account the mileage). Here you need to focus on what will come before. In addition, it is desirable to perform work, when the fluid is brown.

What antifreeze is better pouring in Skoda Octavia?

For cars that are manufactured in 1996-1997, antifreeze class G11 (green). The resource of this coolant is 3 years. Optimal options - Aral Extra, Mobil Extra, Havoline AFC, Genantin Super.
If the car suggested from the conveyor between 1998 and 2002, the replacement of antifreeze is made using the Red Round Class G 12. It serves longer to competitors - 5 years. The most popular brands should include AWM, Glaaself, Freecor, Lukoil Ultra, G-Energy and others.
For Skoda Octavia, which was released between 2003 and 2009 inclusive, the red antifreeze class G12 + is suitable. Optimum option - Lukoil Ultra, Motul Ultra, Freecor.
If the car is made after 2010, only the Red Class G12 ++ class can be pouring into the cooling system. Suitable brands - VAG, FEBI, FREECOR QR, Glysantin G 40.

Replacement process

To replace antifreeze on the car Skoda Octavia, a coolant (about 8 liters), a clean rag and a classic screwdriver, with a horizontal stale. Before starting work, wait for the engine cooling, after which, slowly unscrew the lid on the expansion tank, putting a clean rag from above. Several rotations, along the arrows of the clock, allows you to reset the pressure and avoid splashing the composition. After that, remove the lid completely.

Drain of antifreeze

To merge antifreeze, do the following:

Open the pumping fittings that are mounted on the heater hose to the left of the cylinder block (hereinafter - the BC). Note that the F3R motors provide an additional fitting, on the thermostat case.
Remove the soundproofing shield from the motor, after which, place the prepared container under the bottom tube of the radiator. Loosen the fastening clamp tubes, dismantle it and wait until the old coolant completely leaves the system.

To merge the antifreeze completely, on the machines of Skoda Octavia, with motors 1.4 and 2.0 liters, unscrew the plug cork located on the back of the BC: on the E 7J motor, it is behind the generator, and on the Motors F7R, F3R 750 and F3R 751 - on top of the protective Casing of the intermediate shaft.

If it is planned to replace antifreeze, and the fluid is clean and applied less than 2 years, repeated fill is allowed. But it is still not desirable to do. After performing the above work, install the lower tube of the radiator and the drain plug on the BC.

Flushing radiator

Make a flushing of the radiator. For this:

Drop the tubes that are suitable on top and bottom of the radiator.
Put the garden hose in the opening, which is provided for the top tube of the radiator. Send a stream of water through the radiator, for flushing. Act until the water appears at the outlet of the hole of the lower tube of the radiator.
If, after a few procedures, water does not become cleaner, rinse the radiator using a special tool. Act with the recommendations of the manufacturer. In case of severe pollution, set the tube into the inlet provided for in the bottom of the tank, after which, let the jet for flushing, in the opposite direction.

Fill new antifreeze

The next step in the replacement of antifreeze is filling the system of new coolant. For this:

Close all drained holes.
Check the status of the brackets and tubes.
Remove the plum cover from the expansion tank.
Open the pumping fittings.
Put the rag around the tank.
Fill in the system. Leite until the level of the coolant does not reach the top of the tank neck.
Discharging pumping fittings when coolant will go without air bubbles.

As soon as this work is done, boil the motor and leave it to work for 4-5 minutes. Watch that the revs do not exceed 2500 revolutions. Return to the place the lid of the expansion tank, and leave the engine to work, for another 20 minutes. In the completion of the antifreeze replacement process, on the Skoda Octavia, muffle the motor and check the fluid level in the tank. If he comes to Mach, then everything is normal. Otherwise, perform a plot. At the same time, make sure that the lid on the expansion tank is well tightened.

Now look out until the motor cools, and after, check the level of the coolant again. Put the protective casing, and after 2-3 days, make sure that antifreeze is enough in the system.

The above is a detailed instruction, as applied to Octavia Skoda - how to drain antifreeze, what to take into account, in the system washing the system, as well as how to fill the cooling system of the new coolant. Knowing these features, you can easily make work, with your own hands, and avoid spending on a hundred.

Here we will analyze many unpopular questions:

catalog room cooler for Skoda A5;
what antifreeze to fill in the Skoda Octavia A5;
how and how to dilute concentrate;
how much antifreeze in the cooling system in Octavia;
when replacing the pump, how many in the system will need to pour antifreeze;
what color can be addressed;

On the mileage of 7,800 km, the coolant level at my Skoda was at a minimum.

If anyone knows what antifreeze near Skoda Octavia A5It is recommended to use G13 to the system. We used to Lily G12, but since 2012 is not produced, instead of it G13. They can be mixed.

Color - purple.

Who will encounter similar:
If you add to the cold when it was below the minimum, you have a hot maximum on you. If not strongly overflow, the level will fall over time. But watch! Here I was told before.

Catalog number of the original - G 013 A8J M1 - Fluid for cooling system.

How to dilute the concentrate and in what proportion?

The photo above canister 1.5 liters. G12 ++.
Divated one to one with distilled water (i.e. 1 liter of concentrate + 1 l d.Vody).
As a result, got a cooling of frost resistance minus 35 degrees. Rolled 100 gr.

How much antifreeze clides in full replacement on the Skod

Motor 1.4 - 7.7 l
Motor 1.6 - 7.4 l
Motor 1.8 - 8.6 l
Motor 2.0 - 8.6

Diesels in all motors - 8.4

As in fact:

By 1.6 changed less than 5 liters. Because it does not merge from the entire system, but only from the engine.
At 1.4, about 3 liters entered.
By 1.8, 8 liters took full volume.

In the photo, the new G13, too, is 1.5 liter.

Red antifreeze flooded on Skoda - what color to attach, any red or ...?

Often the question is asked: can any red or not?

Here we rely on the following moments.

Globally, you can add to the desired level any red, but it is better to pour / add what nature is written. Those, what is recommended by the manufacturer, and this is G12 + +. It is not recommended to mix it with others.

Do not pour a decky type Rosneft - the whole system rusts from such shit.
If you pour into the car everything fell, it will not end.
If you need a little - a fraction of distilled water.
Key - a little and without breaking the proportion!

If you decide to make the replacement of antifreeze completely, you still use the cooling fluid recommended by the manufacturer.

Personally my opinion - the colors are better not to mix and pour / add the original.

Do I need to wash the cooling system when replacing the antifreeze of another color?

Yes, you need, but as you understand, you don't have all the entire system.

What mileage is changing antifreeze around the plant

Antifreeze has a service life, therefore, according to the manufacturer's recommendation, replacing the coolant should be replaced after 6 years of operation or 90 thousand km of NPUBEG, depending on what comes before.

In the internet, it is increasingly possible to meet articles, such as "The color of antifreeze on its technical characteristics does not affect."

For example,

Myth 4. About the color of antifreeze.

Among motorists are the wrong idea that the color of antifreeze is associated with its quality. The most common "classification" sounds like this:

red antifreeze best, it serves 5 years,
Green antifreeze average serves 3 years,
Blue antifreeze, including Tosol, the most "simple" serves 1, a maximum of 2 years.

Also there is absolutely incorrect view that all antifreeze of one color are the same, and that they can be mixed with each other. Often, drivers buy antifreeze (for replacement or topping) only because it is the same color as the car flooded in the car.

Enontending producers of cooling liquids to expand the range are available on sale antifreeze of different colors: both red, and green, and blue, even yellow, although they can be absolutely the same in their composition. On the contrary, antifreezes of the same color can be completely different and disheighted among themselves.

In fact, all antifreeze (and toosols) initially colorless. Manufacturers add a dye to them only to give "individuality" and to improve the visibility of the fluid level in the expansion tank. Sometimes the dye is fluorescent to determine the places of leaks. The amount of dye is minimal - several grams per ton. There is no relation to the properties of antifreeze.

Usually, the color of antifreeze is the subject of agreement between the manufacturer and the consumer. For example, our enterprise, JSC Tehnoform, produces the same antifreeze "Cool Stream Premium" of orange color (with the addition of orange dye) for the Ford Automobile Plan, Vsevolozhsk, Yellow Color for Volvo, Kaluga, Pink Color for GM -OPEL, St. Petersburg, blue for Komatsu, Yaroslavl. In retail sale, this antifreeze comes with orange colors, as for Ford.

Engine overheating can be considered one of the fastest breakdowns for the car. Of course, it all depends on the degree of overheating, but even the slightest increase in temperature indicates a cooling system malfunction, which in the future, if not adopting proper measures, can lead to a planning result.

Cooling fluid varieties for octavia

With the invention of the first internal combustion engines in front of the engineers there was a question of their high-quality cooling. Initially, air and water cooling was used for this. However, it became clear that they have a number of significant deficiencies, and chemists began to look for new methods of cooling mechanisms. In the 20s of the last century, they appeared the world of antifreeze - chemical mixtures with high thermal conductivity and extreme phase transition temperatures (shift of the aggregate state).

Modern antifreezes are made on the basis of ethylene and propylene glycol, with the addition of water and various protective additives. In terms of additives and chemical compounds, they are distributed over several groups:

Traditional. Appeared among the first. Contain additives on an inorganic basis. Have a short service life (no more than 2 years) and a relatively low boiling point. It is also the cause of education on the details of the cooling system of the oxide film that interferes with the high-quality heat pipelines.
Carboxylate. GENERAL MOTORS was introduced. Contain organic additives and carboxylic acid salts. Forming a protective film of 0.1 microns in the places of corrosion. Service life, compared to traditional antifreezes, increased to 5 years.
Hybrid. With the addition of both organic and inorganic additives.
Low-hybrid. Developed at the beginning of the XXI century. Contain the minimum number of inorganic silicates during organic basis. The interval of replacement of such liquids can be 500 thousand km and above.

There is no single standard labeling standard, but spontaneously used to use the classification created by Volkswagen Audi Group. For it, liquids are divided into three categories: G11, G12. and G13.

Cooling fluids G11 are the most accessible of all. They are made on the basis of ethylene glycol with the addition of organic additives containing silicates. Silicates, in this case, provide limited protection of the system from corrosion, covering it with a thick protective layer. Most often, the color of the liquid is blue or green.
Class liquids G12 They have preferably red and are slightly more expensive and high-quality than G11. Instead of silicates, the additive package contains carboxylate compounds that are covered by a protective anti-corrosion layer not the entire system, but only those places where it is necessary. In this case, the thickness of the layer is at times less, which improves the heat sink.
Antifreeze with marking G13 are the most expensive from this category. They do not contain silicates and are created on the basis of environmentally friendly propylene glycol. This is high-quality, environmentally friendly protection. Typically, produced painted in yellow or orange colors.

By the way, the color of the fluid does not affect its quality and is not derived from any beneficial chemicals. Liquids are painted in different colors by the manufacturer for the convenience of labeling and diagnosing possible leaks in the car.

On the Skoda Octavia A5, the coolant replacing the manufacturer recommends using the original G12 ++ mixture of the VW TL-774G OEM. In the cars issued until 2011, you can pour the G12 ++ series TL-VW 774G or G-012-A8G-M1. For everything that came out after 2011, antifreeze G13 TL-VW 774J has been used.

Why change coolant liquid?

Over time, antifreeze in the car cooling system starts to grow old. The cavitation of fluid increases, the formation of foam begins. The concentration of inhibitors is reduced, which leads to the formation of corrosion and scale in the system. Some few high-quality fluids leave a precipitate and a raid, which clogs the pipes and system channels, relaxing its heat sink. Natural evaporation and possible refrigerant leaks are added to this.

According to the Regulations in Skoda Octavia A5, the coolant replacement is carried out once every 5 years or when 250 thousand km of mileage is achieved. However, the urgent change of antifreeze may be required if troubleshooting occurs.

The main sign of problems is the engine overheating. With a weak overheating, the motor begins to stroke on a powerful rift, with a stronger - from under the hood can be simmer. Another sign of overheating and / or problems in the cooling system is the substitution of cold air from the stove in the cabin hot.

Special troubles deliver antifreeze leaks. To diagnose leak and its location must pay attention to the following signs:

fogging glass in the cabin, the formation of condensate under the front passenger seat or in the area of \u200b\u200bthe diagnostic connector indicate that the leakage takes place at the level of the heating radiator of the car;
traces of moisture under the car and moisturizing the cooling radiator tubes indicates their damage or depressurization of their fasteners. In the latter case, it is most often enough to change the sealing rings;
white sweet smoke from the muffler, as well as a white raid on the dipstick when checking the oil means that antifreeze leakage occurred in the oil pipeline;
leaks in motigel are diagnosed in a car service. They indicate the formation of a white plaque on the ignition candlelight when removing them.
also loss of fluid can be at the level of the expansion tank. You can check its integrity in the process of visual inspection.

If one or more of these features is detected, it is necessary to make the necessary repair as soon as possible and replace antifreeze in the system to a new one.

Below we will understand the replacement process of the coolant in more detail and give step-by-step instructions for this work.

Preparation for replacement

First of all it is necessary to remember that the replacement of the coolant on the Skoda Octavia A5 is carried out with the maximum cooled engine. With hot antifreeze, the pressure in the system increases due to the expansion of fluid and steam. Their temperature can be high enough to cause heavy skin burns and face, as well as eye damage. Therefore, work is carried out with a cold engine and in protective clothing.

You need the following instruments:

set of wrench keys with heads of different sizes;
pliers or Passatii;
means for washing the cooling system channels;
at least 15 liters of distilled water;
about 8 liters of coolant;
capacity for collecting at least 10 liters.

Step-by-step regime replacement

The work takes place in three stages: the drain of the old refrigerant, washing the system and the fill of the new liquid. Consider the process of replacing antifreeze step by step:

We dismantle the engine protection shield by unscrewing the fastening bolts with appropriate keys.
Reset pressure in the system. To do this, open the lid of the expansion tank (carefully, so as not to be covered with hot steam), in order to give air current.
We drain antifreeze from the cooling radiator. We substitute the container to collect the old fluid under the radiator, with the help of the passage we spawned the clamp from the lower hose and, removing the hose from the nozzle, omit it into the container. Liquid should merge sambeck.
In the same way, disconnect the hose of the fuel tank and descend the liquid from it. After that, we install the hose in place.
We find the plug hole on the engine cylinder block. Substituting the container under it, unscrew the cork and let antifrase quietly drain.
After the exhaust refrigerant fully follows, without closing the drain holes, fill in the expansion tank with 5-6 liters of distilled water. Thus, a certain amount of garbage and oxidation products will be washed out of the system.
We close all the holes for the drain. Pour into the expansion tank to wash the means for flushing and follows it several liters of distilled water (to the level of mines in the expansion tank). We close the lid and turn on the motor.
We warm the car until the cooling fan is turned on.
The moach motor and again drain all the liquid from the system.
We wash the system by distillate several times, as they did in step 6.
We finally close the drain holes, replacing the seals if necessary. It's time to pour a new antifreeze.
Create a mixture of antifreeze and distillate in the necessary proportions. The proportions in which these substances are mixed depend on the operating conditions of the car and the required characteristics of the fluid. The boiling and freezing temperature of the mixture will also depend on proportions.
The recommended proportion is written on the label of the antifreeze used, but usually this number is 3/2, where 2 parts of the distillate are taken on 3 parts of the refrigerant. The total volume of the resulting mixture should be about 9 liters.
We pour the mixture into the expansion tank to the level of minimum. After that, we put the engine and leave it to work until the fan is turned on. After that, we fill the fluid into the expansion tank to the maximum level and close it.

Well cool the engine, circulate through the system and at the same time do not freeze in the cold - these are the main properties of the coolant that your car requires! At the same time, it, like any product, can lose properties. Then only a qualified antifreeze replacement will help.

When maybe you need to replace antifreeze on Skoda Octavia A5?

You need to change the cooling fluid by relying on the manufacturer's recommendation and taking into account the operating conditions. Necessarily - in emergency cases, as well as when such signs are manifested:

ATTENTION! After repairing the cylinder block, only new antifreeze should be replaced by the replacement of its gasket and the radiator. This will be useful both for the cooling system as a whole and on the replaceable and repaired details on which fresh anti-corrosion protection will be formed.

If the replacement of antifreeze on Skoda Octavia A5 will not be carried out on time, the details will be exposed to greater corrosion, the engine will overheat, work worse and with failures. The planned replacement on this model is recommended every 60,000 mileage kilometers. But these are averaged figures relating to the average operating conditions of the car and the ambient temperature.

Replacing Antifreeze Octavia A5 Alone: \u200b\u200bIs it worth risking?

Customers of our car service, noticing how quickly the case arises in the hands of masters, deceive themselves the opinion that the replacement of the antifreeze OCTAVIA A5 labor will not be.

However, there are your underwater stones here:

Alone completely remove the old antifreeze is unlikely to succeed. Some of his share is mixed with the new one. As a result, the durability and properties of a newly spilled liquid decrease. But worse - exactly on those 15-20 percent remaining in the system, and there is a large share of sediment, negatively affecting the system.
On some models, the slip of the place of refueling is located differently. In some, for example, there is a drain fitting, another motorist will have to look for a drain bolt on the radiator.
And the most common mistake leading later to the overheating of the engine is to leaving air traffic jams.

FOR REFERENCE. In the car service for this operation, thermostat, hoses, nozzles are dismantled. Everything is installed and securely attached, if necessary, some elements are replaced with new ones. Our masters are perfectly familiar with the design of all models, which significantly reduces the time for work. On the network of our car services, various methods are applied up to vacuum.

The difficulties of choosing a new antifreeze, when the cooling fluid is replaced by Skoda Octavia A5

A separate theme of any of the masters would like to devote the choice of antifreeze. The case is complicated by the choice of labeling, producer and volume. The question arises and on the concentration of coolant for replacement.

As for exactly the Skoda Octavia A5, then 8.4 liters circulates in its cooling system. Recommended for use:

for cars release until June 2011 - G12 ++ Specifications OEM VW TL-774G (or VAG G 012 A8G M1);
for release cars after this period - G13 TL-VW 774J standard.

The question arises: "What will happen if they are mixed?", To which the masters give the question: nothing terrible, it is quite acceptable. Simply this marking is recommended by the manufacturer to improve the efficiency of the engine cooling. Properties of them are similar, but antifreeze class above more environmentally.

Capacities can be different, and the concentration of antifreeze in the coolant is also. Only in the workshop it will not be breeding with water from under the tap - it requires distilled water. From the proportion of concentration depends the property of frost resistance of the liquid. The consistency is communicated with the climatic conditions (for frosty winters) and the wishes of the client.

Replacing antifreeze Skoda Octavia A5 TSI

On the one hand, the procedure of plum, bay, cleaning system, its diagnostics, etc. Different series of Skoda Octavia A5 does not differ in principle. On the other hand, TSI with turbocharging compared to MPI, conventional atmospheric engines, have higher frequency speeds. That is, with high power, they require greater cooling and antifreeze above quality, as well as attention to detail.

And here car enthusiasts again allow some errors. For example, they begin to replace the hot engine, without giving it to cool. They can get a burn, as well as step by pairs, to obtain skin damage (antifreeze toxic). Ourselves also harm the environment, merging the old spent coolant directly behind its garage.

ATTENTION! In the car service, when the antifreeze of Skoda Octavia A5 TSI is replaced, all stages are worked out for years, the safety technique is observed and modern tools are used. Just pour the coolant to the system and continue to ride your car. It is necessary to run the engine and overclock up to two thousand revolutions per minute, then produce a tank. Much will say and check the system after the procedure - the temperature sensor, the time of turning on the fan, air coming out of the heater, etc.
