There are no original liquids, neither oil nor antifreeze; there are tolerances for us, this is VW approval, I don’t know of antifreeze, but I do not know the tolerance for oil VW-502 00 and 505 01. Found antifreeze approval TL774D fits G-11 .G-12 .G-12 + and G- 12 ++. You can fill in any as it fits according to the tolerances, it is not necessary that VW be written there. I do not recommend pouring antifreeze A-40 through the head.
.

For God's sake, you can assume that there is no! I will not persuade anyone. But, manufacturers and foreign official car dealers think exactly the opposite! I have already mentioned that I worked in Europe for 4 years and in the course of my work I talked to official dealers for tonsils! I want to say that THEIR dealers are fundamentally different from OUR in terms of professional training! And THERE the original oils and technical fluids are those that are poured into the engine on the conveyor. It was there that I bought 5 liters of the original G12 + concentrate in reserve. By the way, about the oil. Everything is correct about the tolerances. Only you have indicated the tolerance for your engine. For a diesel engine, it is different - 503 00, 506 00, 506 01. For TSI, if I’m not mistaken, 507 00, 507 01. But what’s interesting, at the TAM service they poured oil from such an interesting canister, on the label of which it was written in large letters WV, then - viscosity grade, quality group, specification and - made in Germany. When I asked what kind of oil it was, the service engineer answered - the original Volkswagen oil, which is poured on the conveyor. To my question, where it is made and where it is taken from, he pointed to the inscription on the canister - in Germany, at the enterprises of the Volkswagen group, and they receive it by direct deliveries from there.
I wonder if this is a fantasy of foreign car dealers?
About antifreeze for Skoda. In my manual it is written in bold: use only G12 or G12 +, G12 ++. Not a word about the G11. And in the operation and repair manual it is said that it is allowed to use other cooling liquids that have Volkswagen approval, but it must be replaced every 2 years! When using antifreeze G12 and above (with a + sign), Skoda does not provide for its scheduled replacement at all! Except when distilled water was used for topping up, as a result of which the density of the antifreeze could decrease. Reproduced almost verbatim. Although some professionals believe that over time, any antifreeze deteriorates due to the loss of the properties of inhibitor additives and recommend its preventive replacement after 5-7 years or 100,000 km.
By the way, in one of the issues "Behind the Wheel" this year there was a very interesting test of antifreezes. And there were 3 or 4 badged G12. The result of laboratory analysis: of all, only one more or less met the parameters of the original G12. The rest were not even close!
So, if the opinion of professionals means little to you, pour what you want, the cars are yours, and then you will have to disentangle the fruits of dubious savings!
For me, it’s better to pay once, fill the original, and forget about it for the whole time while you are driving. If the antifreeze goes away, look for the reason. It is better to find and eliminate it once, than every time to be tormented by the question of what to pour and what will happen next. The cooling system is sealed and the antifreeze should not decrease! An example of this is my car. She is already 6 years old, and has never (!) Been refilled with antifreeze, and it is still at the MAX level!

Taking into account the recommendations of the manufacturer, the replacement of antifreeze in Skoda Octavia cars is made every 6 years, or after 90,000 km (if the mileage is taken into account). Here you need to focus on what comes first. In addition, it is advisable to perform the work when a brown tint of the liquid appears.

What antifreeze is better to pour into the Skoda Octavia?

• Antifreeze class G11 (green) is suitable for cars that were produced in the period 1996-1997. The service life of this coolant is 3 years. The best options are Aral Extra, Mobil Extra, Havoline AFC, Genantin Super.
• If the car rolled off the assembly line between 1998 and 2002, the antifreeze is replaced using a red coolant of class G 12. It lasts longer than competitors - 5 years. The most popular brands include AWM, GlasElf, Freecor, Lukoil Ultra, G-Energy and others.
• For Skoda Octavia, which was produced between 2003 and 2009 inclusive, red antifreeze of the G12 + class is suitable. The best option is Lukoil Ultra, MOTUL Ultra, Freecor.
• If the car was produced after 2010, it is necessary to pour only red coolant of the G12 ++ class into the cooling system. Suitable brands are VAG, FEBI, Freecor QR, Glysantin G 40.

Replacement process

To replace antifreeze on a Skoda Octavia car, you need coolant (about 8 liters), a clean rag and a classic screwdriver with a horizontal blade. Before starting work, wait for the motor to cool, then slowly unscrew the cap on the expansion tank, placing a clean rag on top. Several rotations, in the direction of the clock hand, allows you to relieve pressure and avoid splashing the composition. After that, remove the cover completely.

Draining antifreeze

To drain the antifreeze, do the following:

• Open the bleed fittings, which are mounted on the heater hose, to the left of the cylinder block (hereinafter - BC). Please note that the F3R motors have an additional fitting on the thermostat housing.
• Dismantle the soundproofing plate from the motor, then place the prepared container under the lower radiator tube. Loosen the pipe retaining clip, remove it and wait until the old coolant has completely left the system.

To drain the antifreeze completely, on Skoda Octavia cars, with 1.4 and 2.0 liter engines, unscrew the drain plug located on the back of the BC: on E 7J engines it is located behind the generator, and on F7R, F3R 750 and F3R 751 motors - on top of the protective intermediate shaft housing.

If it is planned to replace the antifreeze, and the liquid is clean and has been used for less than 2 years, refilling is allowed. But it is still not desirable to do this. After completing the above work, install the lower radiator tube and drain plug on the BC.

Radiator flushing

Flush the radiator. For this:

• Discard the tubes that fit at the top and bottom of the radiator.
• Place a garden hose in the opening provided for the upper radiator pipe. Direct a stream of water through the radiator to flush. Proceed until water appears at the outlet of the hole in the lower radiator tube.
• If, after several procedures, the water does not become clearer, rinse the radiator using a special tool. Follow the manufacturer's recommendations. In case of heavy contamination, install the tube into the inlet provided at the bottom of the tank, then blow the flushing jet in the opposite direction.

Pouring new antifreeze

The next step in replacing antifreeze is to fill the system with new coolant. For this:

• Close all drain holes.
• Check the condition of the staples and tubes.
• Remove the drain cap from the expansion tank.
• Open the bleed fittings.
• Place a rag around the bowl.
• Complete the system. Pour until the coolant level reaches the top of the filler neck.
• Close the bleed fittings when the coolant flows without air bubbles.

Once this work is done, start the engine and let it run for 4-5 minutes. Make sure that the revolutions do not exceed 2500 revolutions. Replace the expansion tank cap and leave the engine running for another 20 minutes. At the end of the process of replacing antifreeze, on the Skoda Octavia, turn off the engine and check the fluid level in the tank. If it reaches the MAX mark, then everything is normal. Otherwise, top up. When doing this, make sure that the cap on the expansion tank is tightened well.

Now wait until the engine has cooled down, and then check the coolant level again. Replace the protective cover, and after 2-3 days, once again make sure that there is enough antifreeze in the system.

Above are detailed instructions for the Skoda Octavia - how to drain the antifreeze, what to consider when flushing the system, as well as how to fill the cooling system with new coolant. Knowing these features, you can easily do the job, do it yourself, and avoid spending at a service station.

Here we will analyze many unpopular questions:

• chiller catalog number for Skoda A5;
• what antifreeze to fill in the Skoda octavia a5;
• how and with what to dilute the concentrate;
• how much antifreeze is in the Octavia's cooling system;
• when replacing the pump, how much antifreeze will need to be poured into the system;
• what color can be topped up;

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

If anyone does not know what antifreeze does the Skoda octavia a5 have? then it is recommended to use G13 to top up the system. Previously, we poured G12, but since 2012 it has not been produced, instead of it G13. They can be mixed.

The color is purple.

Who will face something like this:
If you add to the cold one when it was below the minimum, the hot one is higher than the maximum. If you do not overflow, the level will drop over time. But watch! I have topped up this one before.

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

How to dilute the concentrate and in what proportion?

In the photo above, a canister of 1.5 liters. G12 ++
Diluted one to one with distilled water (i.e. 1 liter of concentrate + 1 liter of water).
As a result, I got a chiller with frost resistance of minus 35 degrees. Topped up 100 gr.

How much antifreeze fits with a complete replacement on Skoda

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

Diesels for all engines - 8.4

How in practice:

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

The photo shows the new G13, also comes with a 1.5 liter.

The Skoda is filled with red antifreeze - what color to add, any red or ...?

The question is often asked: can any red or not?

Here we rely on the following points.

Globally, you can add any red to the desired level, but it is better to fill / top up what nature has prescribed. That is, what the manufacturer himself recommends, and this is G12 + +. It is NOT recommended to mix it with others.

DO NOT pour Deshmanovskaya like Rosneft - the whole system rusts from such shit.
If you pour whatever you get into the car, it will not end well.
If you need a little, add distilled water.
The key is a little and without breaking the proportion!

If you decide to replace the antifreeze completely, then still use the coolant recommended by the manufacturer.

Personally, my opinion is that it is better not to mix colors and pour / top up the original.

Do I need to flush the cooling system when changing antifreeze of a different color?

Yes, it is necessary, but as you understand, you cannot completely flush the entire system.

At what mileage does the antifreeze change at the plant

Antifreeze has a service life, therefore, according to the manufacturer's recommendation, the coolant should be replaced after 6 years of operation or 90 thousand km of run, whichever comes first.

More and more often you can find articles on the Internet, such as "the color of antifreeze does not affect its technical characteristics."

For example,

Myth 4. About the color of antifreeze.

There is a misconception among motorists that the color of antifreeze is related to its quality. The most common "classification" goes something like this:

red antifreeze is the best, it lasts 5 years,
medium green antifreeze, lasts 3 years,
blue antifreeze, including Antifreeze, the most "unpretentious", lasts 1, maximum 2 years.

There is also an absolutely wrong opinion that all antifreezes of the same color are the same, and that they can be mixed with each other. Often, drivers buy antifreeze (for replacement or topping up) just because it is the same color as the one filled in the car.

Enterprising manufacturers of coolants to expand their assortment put on sale antifreezes of different colors: red, green, 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 immiscible with each other.

In fact, all antifreezes (and antifreezes) are initially colorless. Manufacturers add dye to them only to give "individuality" and to improve the visibility of the liquid level in the expansion tank. Sometimes the dye is fluorescent to locate leaks. The amount of dye is minimal - a few grams per ton. Its color has nothing to do with the properties of antifreeze.

Usually, the color of antifreeze is subject to agreement between the manufacturer and the consumer. For example, our enterprise, JSC TECHNOFORM, produces the same orange Cool Stream Premium antifreeze (with the addition of orange dye) for the Ford automobile plant, Vsevolozhsk, yellow for Volvo, Kaluga, pink for GM -Opel, St. Petersburg, blue for Komatsu, Yaroslavl. This antifreeze is available in retail in orange color, as for Ford.

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

When may you need to replace antifreeze with a Skoda Octavia A5?

It is necessary to change the coolant based on the manufacturer's recommendations and taking into account the operating conditions. Without fail - in case of emergency, as well as when the following signs appear:

ATTENTION! After repairing the cylinder block, replacing its gasket and radiator, only new antifreeze should be filled. This will be useful both for the cooling system as a whole and for parts being replaced and repaired, on which fresh corrosion protection will be formed.

If the replacement of the antifreeze with the Skoda Octavia A5 is not carried out in time, the parts will be subject to more corrosion, the engine will overheat, work worse and malfunction. A planned replacement for this model is recommended every 60 thousand kilometers. But these are average figures referring to average vehicle operating conditions and ambient temperatures.

Replacing Octavia A5 antifreeze yourself: is it worth the risk?

Customers of our car service, noticing how quickly the matter is in the hands of the masters, deceive themselves with the opinion that replacing Octavia A5 antifreeze will not be difficult for them.

However, there are pitfalls here:

• It is unlikely that it will be possible to completely remove the old antifreeze on your own. Some of it will mix with the new. As a result, the durability and properties of the newly filled fluid are reduced. But even worse, it is precisely those 15-20 percent remaining in the system that account for a large proportion of sediment that negatively affects the operation of the system.
• On some Skoda models, the filling points are located differently. In some, for example, there is a drain fitting, in others the motorist will have to look for a drain bolt on the radiator.
• And the most common mistake that subsequently leads to overheating of the engine is leaving air jams.

FOR REFERENCE. In a car service for this operation, the thermostat, hoses, and branch pipes are dismantled. Everything is installed and securely fastened, if necessary, some elements are replaced with new ones. Our craftsmen are perfectly familiar with the design of all models, which significantly reduces the time for work. In our network of car services, various methods are used, up to evacuation.

Difficulties in choosing a new antifreeze when the Skoda Octavia A5 coolant is to be replaced

Any of the masters would like to devote a separate topic to the choice of antifreeze. The matter is complicated by the choice of labeling, manufacturer and volume. The question also arises regarding the concentration of the replacement coolant.

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

1. for cars manufactured before June 2011 - G12 ++ OEM VW TL-774G specifications (or VAG G 012 A8G M1);
2. for vehicles produced after this period - G13 of the TL-VW 774J standard.

The question arises: "What will happen if you mix them?" It's just that this marking is recommended by the manufacturer to improve the cooling efficiency of the motor. Their properties are similar, however, antifreeze of a higher class is more environmentally friendly.

Capacities can be different, and so does the concentration of antifreeze in the coolant. Only in the workshop it will not be diluted with tap water - distilled water is required here. The frost resistance properties of the liquid depend on the proportion of the concentration. The consistency is adjusted taking into account the climatic conditions (for frosty winters) and the wishes of the client.

Replacing antifreeze Skoda Octavia A5 TSI

On the one hand, the very procedure of draining, filling, cleaning the system, its diagnostics, etc. different series of Skoda Octavia A5 do not fundamentally differ. On the other hand, the turbocharged TSI compared to MPI, conventional naturally aspirated engines, has higher revs in a wide frequency range. That is, with increased power, they require more cooling and higher quality antifreeze, as well as attention to detail.

And here motorists again make some mistakes. For example, they start replacing on a hot engine without letting it cool down. They can get burned, as well as breathe in vapors, and damage the skin (antifreeze is toxic). They themselves also harm the environment by draining old used coolant right behind their garage.

ATTENTION! In a car service, when the Skoda Octavia A5 TSI antifreeze is replaced, all stages have been worked out for years, safety precautions are observed and modern tools are used. You cannot simply pour coolant into the system and continue driving your car. It is necessary to start the engine and accelerate to two thousand revolutions per minute, and then top up. Checking the system after the procedure will also say a lot - the temperature sensor, the time the fan is turned on, the air coming out of the heater, etc.

Skoda Octavia A5 coolant replacement: the price of professional help

Some clients, after completing an order, are sincerely surprised: "I thought that since you have professionals, it will be very expensive." This is another misconception. The pricing in our car service is quite fair.

The cost of all work is fixed in price lists, which each client can familiarize with even before ordering. In addition, he can apply for additional services - repairing the cooling system, flushing it, etc. You can be sure that the engine of your car will be cooled with the most optimal concentrate, counterfeits are excluded. Air congestion in the system and other troubles after the Skoda Octavia A5 coolant is replaced, too. The work is carried out quickly, without unnecessary delays, and a guarantee is given for each.

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

Varieties of coolant for Skoda Octavia

With the invention of the first internal combustion engines, engineers were faced with the question of their high-quality cooling. Initially, air and water cooling were used for this. However, it became clear that they have a number of significant drawbacks, and chemists began to look for new methods of cooling mechanisms. In the 20s of the last century, they showed the world antifreezes - chemical mixtures with high thermal conductivity and extreme temperatures of phase transition (change of state of aggregation).

Modern antifreezes are made on the basis of ethylene and propylene glycol, with the addition of water and various protective additives. According to the composition of additives and chemical compounds, they are divided into several groups:

• Traditional. They were among the first to appear. Contains inorganic additives. They have a short service life (no more than 2 years) and a relatively low boiling point. They are also the reason for the formation of an oxide film on the parts of the cooling system, which interferes with high-quality heat conduction.
• Carboxylate. Were introduced by General Motors. Contains organic additives and carboxylic acid salts. Forms a 0.1 micron protective film in places where corrosion occurs. The service life, in comparison with traditional antifreezes, has been increased to 5 years.
• Hybrid. With the addition of both organic and inorganic additives.
• Low hybrid. Developed at the beginning of the XXI century. They contain a minimum amount of inorganic silicates with an organic base. The replacement interval for such fluids can be 500 thousand km or more.

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

• Coolants G11 are the most affordable 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 corrosion protection to the system by covering it with a thick protective layer. Most often, the color of the liquid is blue or green.
• Class fluids G12 are predominantly red in color and are slightly more expensive and better quality than the G11. Instead of silicates, the additive package contains carboxylate compounds, which do not cover the entire system with a protective anticorrosive layer, but only those places where it is necessary. At the same time, the layer thickness is several times smaller, which improves heat dissipation.
• Antifreezes with markings G13 are the most expensive of this category. They do not contain silicates and are based on environmentally friendly propylene glycol. This is a high quality, environmentally friendly protection. As a rule, it is produced in yellow or orange colors.

By the way, the color of the liquid does not affect its quality and is not derived from any useful chemicals. The fluids are painted in different colors by the manufacturer for ease of marking and diagnostics of possible leaks in the car.

The manufacturer recommends replacing the coolant on the Skoda Octavia a5 using the original mixture G12 ++ of the OEM VW TL-774G specification. Cars manufactured before 2011 can be filled with G12 ++ of the TL-VW 774G or G-012-A8G-M1 series. For everything that came out after 2011, G13 TL-VW 774J antifreeze is already used.

Why change the coolant?

Over time, the antifreeze in the car's cooling system starts to age. The cavitation of the liquid 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 low-quality fluids leave sediment and sludge that clogs the pipes and channels of the system, weakening its heat dissipation. Added to this is natural evaporation and possible refrigerant leaks.

According to the regulations in the Skoda Octavia a5, the coolant is replaced every 5 years or upon reaching 250 thousand kilometers. However, an urgent change of antifreeze may be required if there is a problem with the cooling system.

The main symptom of a problem is engine overheating. With a slight overheating, the engine begins to stall on a powerful traction, with a stronger one, smoke can pour out from under the hood. Another sign of overheating and / or problems in the cooling system is the replacement of cold air from the heater in the cabin with hot air.

Antifreeze leaks are especially troublesome. To diagnose leak and its location, you need to pay attention to the following signs:

• fogging of the windows in the passenger compartment, the formation of condensation under the front passenger seat or in the area of ​​the diagnostic connector indicate that a leak takes place at the level of the car's heating radiator;
• traces of moisture under the car and wetting of the radiator tubes indicate damage to them or leakage of their mountings. In the latter case, it is often enough to change the O-rings;
• white sweetish smoke from the muffler, as well as a white coating on the dipstick when checking the oil, means that antifreeze has leaked into the oil line;
• engine leaks are diagnosed at a car service. They are indicated by the formation of white deposits on the spark plugs when they are removed.
• also, the loss of liquid can be at the level of the expansion tank. You can check its integrity during a visual inspection.

If one or more of these signs are found, it is necessary to make the necessary repairs as soon as possible and replace the antifreeze in the system with a new one.

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

Preparing for replacement

First of all, it is worth remembering that the replacement of the coolant on the Skoda Octavia a5 is carried out with the engine cooled as much as possible. With hot antifreeze, the pressure in the system increases due to the expansion of liquid and vapor. Their temperature can be high enough to cause severe burns to the skin of the hands and face, as well as damage to the eyes. Therefore, work is carried out with a cold engine and protective clothing.

You will need the following tools:

• a set of wrenches with heads of different sizes;
• pliers or pliers;
• means for flushing the channels of the cooling system;
• at least 15 liters of distilled water;
• about 8 liters of coolant;
• collection container with a volume of at least 10 liters.

Step-by-step instructions for replacing the coolant

The work takes place in three stages: draining the old refrigerant, flushing the system and filling with new fluid. Consider the process of replacing antifreeze step by step:

1. Dismantle the engine protection shield by unscrewing the fastening bolts with the appropriate wrenches.
2. We relieve the pressure in the system. To do this, open the cover of the expansion tank (carefully so as not to scald with hot steam) in order to give air flow.
3. We drain the antifreeze from the cooling radiator. We substitute the container for collecting the old fluid under the radiator, with the help of pliers we unclench the clamp from the lower hose and, removing the hose from the nozzle, we lower it into the container. The liquid should drain off by gravity.
4. In the same way, we disconnect the hose of the filler tank and drain the liquid from it. After that, we install the hose in place.
5. We find the drain plug on the engine block. Substituting a container under it, unscrew the cork and let the antifreeze drain calmly.
6. After the spent refrigerant has completely drained out without closing the drain holes, fill the expansion tank with 5-6 liters of distilled water. This will flush some debris and oxidation products out of the system.
7. We close all the drain holes. Pour the flushing agent into the expansion tank, followed by several liters of distilled water (up to the MIN level in the expansion tank). We close the lid and turn on the motor.
8. We warm the car until the cooling fan turns on.
9. We turn off the engine and again drain all the liquid from the system.
10. Flush the system with distillate several times, as we did in step 6.
11. We finally close the drain holes, replacing the seals if necessary. It's time to fill in new antifreeze.
12. We create a mixture of antifreeze and distillate in the required proportions. The proportions in which these substances are mixed depend on the operating conditions of the vehicle and the required characteristics of the fluid. The boiling and freezing point of the mixture will also depend on the proportions.
    The recommended proportion is written on the label of the antifreeze used, but usually this number is 3/2, where 2 parts of distillate is taken for 3 parts of refrigerant. The total volume of the resulting mixture should be about 9 liters.
13. Pour the mixture into the expansion tank to the MINIMUM level. After that, we start the engine and leave it running until the fan is turned on. After that, add liquid to the expansion tank to the maximum level and close it.
