When buying, you need to know the shade - Color and A type Antifreeze, permissible for the year of release of your Octavia 2. Manufacturers choose at its discretion. Do not forget - each type of fluid has its own service life.
For example: For Skoda Octavia (2nd generation) 2004 GV, with a gasoline or diesel engine type, the carboxylate antifreeze class is suitable, the G12 type with shades of red. The approximate term of the next replacement of which will be 5 years old. Opportunity, deposit the selected fluid for compliance with the requirements of the vehicle manufacturer specifications and maintenance intervals. It's important to know Each type of fluid is its color. There are rare cases when the type is tinted with different color.
The color of red antifreeze can be from violet to light vehicle (in green and yellow the same principles).
Mix liquid from different manufacturers - canIf their types correspond to the mixing conditions. G11 can be mixed with analogs G11 G11 can not be mixed with G12 G11 can be mixed G12 + G11 you can mix G12 ++ G11 can be mixed G13 G12 can be mixed with analogs G12 G12 can not be mixed with G11 G12 can be mixed with G12 + G12 can not be mixed with G12 ++ G12 can not be mixed with G13 G12 +, G12 ++ and G13 can be mixed with each other. Antifreeze with Tosol is not allowed. No way! Tosol and antifreeze are very different in quality. Tosol is the trade name of the traditional type (TL) of the cooling fluid of the old sample. At the end of the service life - the liquid is completely discolored or faster. Before replacing one type of liquid to another, rinse the car radiator with ordinary water. . Additionally

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 may 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:

1. We dismantle the engine protection shield by unscrewing the fastening bolts with appropriate keys.
2. 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.
3. 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.
4. 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.
5. We find the plug hole on the engine cylinder block. Substituting the container under it, unscrew the cork and let antifrase quietly drain.
6. 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.
7. 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.
8. We warm the car until the cooling fan is turned on.
9. The moach motor and again drain all the liquid from the system.
10. We wash the system by distillate several times, as they did in step 6.
11. We finally close the drain holes, replacing the seals if necessary. It's time to pour a new antifreeze.
12. 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.
13. 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.

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.

Timely allows you to avoid overheating of the motor and extend the service life of the pump bearings, and accordingly, to ensure normal operation of the timing of the MRM.

Periodicity

The quality of the liquid, filled into the cooling system of the Skoda Octavia, should be checked at least once every 30 thousand km or every 2 years. Many masters recommend controlling its density and freezing temperature 2 times more often, i.e. On each planned technical inspection. If the "cooler" parameters deteriorated, the top of the fresh concentrate is allowed to bring the characteristics and level to normal.

Spare parts

For A4, Tour and A5 (up to restyling) on \u200b\u200bthe conveyor, the original G12 liquid was used, and later - G12 Plus. They must be changed every 90 thousand km (with small runs - every 6 years).

In the period from 2009 to mid-2011, the plant used antifreeze G12 Plus Plus, and then a new product began to be implemented - G13, which are updated only if the system is repaired (ie, there is no need for prophylactic change).

Third-party cooling fluids typically have a fixed service life (this information must be specified on the package).

Order of work

Since the replacement of the coolant on A5 and A7 usually accompanies the repair of the system, we recommend that you perform these works in a hundred.

If you decide to independently replace the antifreeze of your Skoda Octavia, be prepared for various problems:

• the absence of a drain fitting on some of the FROM (at best there is a drain bolt at the bottom of the radiator),
• the ability to merge less than half the volume of old antifreeze (for complete emptying will have to remove the thermostat, disconnect the turbine hoses, radiator nozzles, etc.),
• aircraft formation (guaranteed to get rid of them on A7 you can only vacuuming),
• overheating of the engine at the "delivered" cooling system,
• periodic "glitches" temperature sensor.

Your car will not "boil" in a traffic jam or with intensive overclocking and will not deliver other problems if our service will be engaged in our service

Most of the owners of Skoda Octavia Tour A5 and A7 face the engine overheating problem when the air cooler does not turn on. Motor cooling system 1.6, 1.8, 1.4, TSI, MPI and BFQ have a similar work scheme into which the thermostat is enabled, as well as its body, fan and relay sensor.

In this article we will talk about the device and maintenance of the cooling system on Skoda Octavia cars A5 and A7, BFQ and TSI. We will also touch on the topic of choosing a coolant, as well as answer the question of which volume is necessary.

What principle of work

The cooling system in Skoda Octavia A5 cars has a similar design with other cars and is a closed circuit equipped with an expander.

The engine Skoda Octavia 1.6 BFQ is equipped with a water pump, which runs the coolant on the radiator system and the engine block. To control the temperature, the fan trigger sensor is located on the thermostat housing, and the thermostat itself is performed.

In the coolest condition, the thermostat closes the small outline so that the engine can warm up to the operating temperature as quickly as possible. In the process of heating the motor, the thermostat produces the valve opening, which in turn leads the liquid along a large circle through the radiator. When the coolant in the radiator is heated above 87 degrees, the fan power sensor is triggered. This system works constantly without stopping, so the person does not require attention.

During operation, this scheme begins to malfunction, which will inevitably lead to overheating of the motor. To monitor the operation of this device, you need to constantly monitor the engine temperature on the dashboard.

Diagnostics of faults

Many owners of Skoda Octavia Tour complain of some moments of fan operation, as well as an increased engine temperature BFQ. What a temperature should be, we think everyone knows.

If the Skoda Octavia fan works constantly, most likely, the temperature sensor was unusable on the housing. Another point when the fan works constantly, maybe the relay, which closed the contacts and cannot break them out due to the oxidation of the legs. The relay is turned on by the sensor command, and the fan works constantly.

If the relay turns on, and the operation of the fan has not begun, it may have burned the fuse.

Check the pressure in the cooling nozzles, for this felt the hoses. If the nozzles can be sold with a little effort, it means that the system is fully operational. In cases where the nozzle is under high pressure, and you can hardly surpassed it, perhaps the system is faulty, and there is a air traffic jam.

On the Internet there are a large amount of video material that demonstrates the entire process of diagnosing and repairing the cooling system on Skoda cars Octavia Tour with MPI 1.6 BFQ motors.

To determine which malfunction your car is sick, spend thorough diagnosis.

In no case do not open the lid of the expansion tank on the heated motor, otherwise the large volume of the coolant will break out, and you will get big burns.

We carry out the shift of the sensor and the thermostat

If the fan relay does not work on your Skoda, the fan relay does not work, it can be easily replaced, but to replace the sensor and the thermostat - the work is not from the lungs. You can watch the video on the Internet, how to replace the relay and where it is.

So, proceed to work.

1. To begin with, you need to cool the engine, for this, the car must simultaneously have a few hours in a muted state.
2. Since the work is associated with the depressurization of the contours, you need to drain the liquid into a separate container.
3. Remove the lower radiator hose and drain the entire volume of antifreeze.
4. Unscrew several bolts around the perimeter of the case and remove the thermostat.
5. Carefully clean the surface adjustment of the gasket to the body and lubricate the thin layer of sealant.
6. Install a new part in the case and clamp the bolts with a necessary point.
7. Mock the nozzles and hoses, after which tighten the clamps.
8. Pour the coolant into the expander's tank and run the engine to drive air.

Now we will talk about replacing the radiator fan power sensor.

1. The car must be cooled.
2. For this work it is necessary to use a viewing pit or lift.
3. Remove the bottom hose, which is turned on in the radiator, and drain antifreeze into a separate container.
4. 27 mm key Unscrew the sensor on the radiator.
5. Lubricate the thread with sealant and tighten a new part into the ends of the radiator.

What sealant should be used? Any high temperature.

1. Install the hoses on the radiator and tighten the clamps, then pour the coolant into the expander's tank.
2. Run the engine and make the contours, and also check how the fan turns on.

Choice of oh

There is a huge number of antifreeze types, which are very similar in its composition. We recommend buying antifreeze for Skoda Octavia TSI Tour, as a rule, red. What to pour you, decide for yourself. The volume that is needed for the BFQ Skoda Oktavia Motors is determined by the type of engine and ranges from 4 to 6 liters.

Perform a timely change of antifreeze every two years of operation.

Conclusion

As we could find out, it is possible to make an independent diagnosis and repair of the cooling system on Skoda Octavia MPI vehicles and even need, since you significantly save money. Carefully monitor the operation of the relay and other electrical circuits. Choose high-quality antifreeze for your car and make timely service, the benefit for this there is a video on the Internet.
