When buying, you need to know the shade - Color And Type antifreeze, valid for the year of manufacture of your Astra H. Select the manufacturer of your choice. Do not forget - each type of fluid has its own lifespan.
For example: for Opel Astra (Body H) 2004, with a gasoline or diesel engine type, suitable - carboxylate antifreeze class, type G12 with shades of red. The approximate next replacement period of which will be 5 years. If possible, check the selected fluid against the requirements of the vehicle manufacturer's specifications and service intervals. It is important to know Each type of liquid has its own color. There are rare cases when a type is tinted with a different color.
The color of red antifreeze can be from purple to light pink (green and yellow have the same principles).
Mix liquid from different manufacturers - Can if their types match the blending conditions. G11 can be mixed with G11 analogues G11 must not be mixed with G12 G11 can be mixed with G12+ G11 can be mixed with G12++ G11 can be mixed G13 G12 can be mixed with G12 analogues G12 must not be mixed with G11 G12 can be mixed with G12+ G12 must not be mixed with G12++ G12 must not be mixed with G13 G12+, G12++ and G13 can be mixed together It is not allowed to mix Antifreeze with Antifreeze. No way! Antifreeze and Antifreeze - very different in quality. Antifreeze is the trade name for the traditional type (TL) of an old-style coolant. At the end of the service life - the liquid completely discolors or becomes very dull. Before replacing one type of fluid with another, flush the car radiator with plain water. . Additionally

Late replacement of antifreeze can cause the same harm as poor quality fuel. Antifreeze is engine coolant. A boiling engine in a traffic jam and in the heat - just happens due to the lack of a coolant change. You can easily change the coolant at home, the whole process will take 30 minutes. Many drivers are afraid of a trip to the service, a long wait in line - so the replacement is postponed until the very last moment. This very last moment happens, usually on the roads, at the most inopportune time. How to avoid the development of such situations? Read further in the article.

When should antifreeze be changed?

There is no universal replacement period. There is a standard rule - antifreeze is replaced every 40-50 thousand kilometers. But it is recommended to do it a little earlier.

In addition, the car can be operated in different load modes - therefore, to replace the coolant, it is better to stick to a mileage of 25-30 thousand kilometers. Visually, the need for replacement is visible in the presence of the following indicators:

• Opel Astra h antifreeze leaves - after a long parking of the car, oil stains appear under the engine;
• On the left, smudges of brown liquid appear under the front bumper - Opel Astra H antifreeze flows;
• When opening the tank, the color of the liquid became noticeably more transparent or mushy;
• A very bad signal if there are oil stains inside the tank. This means that the heat exchanger has leaked inside the car engine. The engine oil has mixed with the coolant. In this case, immediately take the car to the service for inspection;
• The volume of Opel Astra H antifreeze is on the initial filling scale;
• Since the last filling, the mileage has been more than 25 thousand kilometers;
• The engine temperature is in the red zone - the cooling mode of the engine will jam it. It is urgent to change the coolant.

Replacement process

The process of changing the coolant in Opel is quite simple. In the Opel Astra J, the replacement of antifreeze is similar to the Opel Astra h, as is the replacement of the Opel Astra G antifreeze. In the listed car models, the principle of operation with the replacement of the refrigerant is the same.

• We are preparing a container for draining the waste liquid. You can take a simple plastic bottle with a volume of 5 liters. At the top we make a hole in the shape of a rectangle 5 by 3 cm. The waste liquid will merge into this hole;
• Stop the engine, it is better to drain the antifreeze when the Opel has been standing for 15-20 minutes;
• We carry out the whole process on a flat platform;
• Buy new coolant from trusted suppliers. In no case from the hands, where the liquid is on the trays under the direct influence of the sun or temperature conditions.

Drain antifreeze

How to drain antifreeze on Opel Astra J or drain Opel Astra H antifreeze - processes are similar in time and complexity.

• Under the front bumper, in the area of ​​\u200b\u200bthe left headlight, we are looking for a coolant drain cone. We substitute the container and unscrew;
• A thin stream of antifreeze will slowly drain. Color - brown or bright pink. Depending on the originally acquired color (indicator - the engine must be cooled with a new liquid);
• Next - pour distilled water into the tank (attention: not from the tap, but purchased distilled water that does not contain chlorine precipitation);
• We carry out washing 5-6 times. The color should be pale pink (blue, yellow);
• Cleaning completed. We drain all the waste liquid into the technical drain (not in domestic conditions - the liquid is poisonous).

Pouring new antifreeze

We select the brand of antifreeze in accordance with the type of engine:

• Marking 11: not very high-quality liquid, fill in as a last resort. Suitable for old models of the Soviet automobile industry or foreign cars;
• Marking G12 (includes carbo-silicate) - high-quality refrigerant, suitable for engines operating at high speeds;
• Marking G13 - contain propylene glycol. No different from the previous type, but does not contain poisonous properties.

The color of the antifreeze doesn't matter. Produced respectively in different combinations. From red and pink to blue and yellow.

The best advice for choosing a coolant is Opel's recommendations. We open the Opel instruction manual on the last page - all brands of consumables are listed there in full.

Replacing Opel Astra N antifreeze is important for optimal engine performance. In the Astra N cooling system, only red (dark orange) antifreeze is allowed, which, during prolonged use, may turn yellow. The recommended Opel is 1940650 or 09194431.

Replacement frequency and volume of antifreeze Opel Astra N

Opel Astra N maintenance regulations require checking the level and color of the coolant every 15,000 km. Replacement should be made when the liquid has greatly changed color, level and density have changed. Some drivers prefer not to bother with the question "when to change antifreeze" and replace every 45,000 km. In any case, regardless of mileage, coolant should be changed every 2 years, since after this time the anti-corrosion additives lose their properties.

How much antifreeze to fill

How to change antifreeze Opel Astra N

Replacing Astra N antifreeze may also be needed when repairing an engine, during which the cylinder head or cylinder head gasket, radiator, and heat exchanger were changed. Change coolant only possible with a cold engine at least a few hours after the trip.

What is OJ and where to put it

You need to understand how often replacement is required. First, such change is necessary for optimal engine performance. That is, it is a coolant that needs to be poured into the cooling system of your car. It moves between the radiator and the system, removing excess heat and, as it were, making sure that the engine does not overheat. Also an important factor is that it will not freeze even in severe frost.

It's not hard to choose an OC

All Opel Astra N require red antifreeze, during long operation it will brighten to orange or yellow. And in no case should you fill in green antifreeze or G11. Because of this, the entire system can fly. Basically, coolant should be replaced at least every two to two and a half years, or at least every 40,000 km, this is important, because after this period the antifreeze will lose its properties and will no longer be able to cool.

What are the main properties of the coolant?

Possession of anti-corrosion and lubricating properties.

Composed of H 2 O and ethylene glycol, a synthetic chemical.

Does not freeze at -60 C.

Boiling point +108 C.

Coolants are also required for warming up, in order to warm up rather than cool the engine. We must not forget that mixing different types with each other is not allowed. and antifreeze with Tosol (antifreeze is the trade name for coolant based on ethylene glycol, sometimes numbers are added to the name).

In addition to a change due to the loss of unique cooling properties, it is possible in the event of an engine repair. In no case should you lose sight of the fact that replacement can only be done on a cold engine.

How is the coolant changed on the Opel Astra?

You will know that a replacement is needed when the fluid becomes tarnished or loses its cran color.

If you are going to change the type of coolant, be sure to flush the radiator with plain water.

The engine must be cold and make sure the car is on a level surface.

It is necessary to open the tank and, putting a hose on the drain cock, empty the cooling system.

Antifreeze is poured into the Opel Astra until it drips from the pipe.

After that, you need to warm up the engine and check the level in the tank, if there is a shortage, add it.

How to choose and replace antifreeze Opel Astra

Opel Astra antifreeze models H and J. Replacement rules, instructions for draining and filling, as well as useful tips on the Astra cooling system.

The choice of antifreeze for Opel Astra

When choosing a coolant for your Astra, the ideal product is a genuine GM product. Any other red liquid marked G11 can act as a substitute. It is very important that Opel Astra antifreeze is filled with one kind, for example, you cannot add red to green or G11 to G12.

Opel Astra H antifreeze replacement

According to the rules, the change of antifreeze in Astra is made every 45 thousand km or every 2 years. You don't need special skills or equipment to replace yourself. Any coolant work can be done on a cooled engine. The vehicle must be on a level surface.

1. First open the expansion tank
2. Then, put a hose on the radiator tube of the drain cock, insert the end into the drain container and turn the cock.
3. To completely drain the Opel Astra cooling system, you must move the clamp holding the throttle body heating tube and remove the nipple from the intermediate tube socket.
4. Fill until it evaporates from the remote nozzle. Then install it in place. Then it is necessary that the engine warms up to operating temperature, and check the level in the expansion tank. If the level is below the required level, top up.

Opel Astra J Antifreeze replacement

Replacement antifreeze.

Opel proper coolant replacement!!

How did I change

Antifreeze replacement Opel Astra J

Opel Astra J coolant change should also be done every 45,000 km or every 2 years.

During the procedure, the car must be on a flat surface. The process algorithm looks like this:

1. First of all, open the cap of the expansion tank.
2. Connect the hose to the drain hole and place the end in a container to drain.
3. Open the faucet.
4. Fill with new product until it escapes the throttle, it must be removed beforehand by loosening the clamp.
5. Check the level with the engine warm, top up if necessary.

Why antifreeze leaving?

Such reasons for Opel Astra enough. Coolant may be leaking from a radiator, pump, or cracked hose. Also, the gateway could be the cause. If the leak is small, then this will help remove special chemical compounds that pour into the Opel Astra expansion tank and plug small holes. But this is a temporary solution.

To avoid air blockages in the system during the filling of funds, it is necessary to periodically heat the radiator pipes.

If a few days after replacing the antifreeze, it has changed color, then it is a fake product and should be drained immediately.

If the cooling system Opel Astra heavily soiled or antifreeze has not been replaced for a long time, it is recommended to wash it. There are special chemicals for this.

After draining the coolant, the system is filled with flushing composition and turns on for about 30 minutes at maximum heating. The composition is then drained and the refrigerant is poured out.
