How much antifreeze is in Daewoo Nexia

The cooling systems for the SOCH and DOCH engines used in the car are almost identical to each other. Each cooling system is a circuit with forced circulation of liquid. For cars supplied to the CIS, the manufacturer recommends using a composition based on ethylene glycol, popularly called antifreeze, as a coolant. The specially developed chemical composition of the liquid allows it not to freeze at significant negative temperatures. Depending on the car model and the type of internal combustion engine, it is important to observe the operating temperature range. On Daewoo Nexia cars, the operating temperature ranges from 90-100 degrees Celsius, which is automatically maintained at the proper level thanks to the installed thermostat.

How to replace coolant on Daewoo Nexia

A Daewoo car needs coolant to perform several elements of work at once. The most basic functional component is cooling in the injector operating system. With normal readings and timely replacement of the coolant, the temperature sensor will show 90-100 C. Therefore, if your readings are higher, then the antifreeze should be replaced with a Daewoo Nexia.

Functions performed by coolant:

Maintains normal temperature conditions during injector operation (temperature sensor indicators).
Maintains low temperature conditions during gearbox operation. (temperature sensor indicators).
Heating the car interior in winter. Antifreeze provides heat in the cabin due to the fact that the engine heats the liquid and the fan circulates it.

Replacing antifreeze in a Daewoo Nexia car should happen every 40 thousand km or once every 2 years, depending on how often you drive the car . This must be done because the quality of the poured substance is constantly deteriorating and susceptible to corrosion.

Radiator on a Daewoo Nexia car

Conclusion

Changing antifreeze on a Daewoo Nexia with your own hands is quite simple; it does not require any special skills or abilities - just follow the instructions and time. Particular attention should be paid to the choice of coolant; the condition of the components and assemblies will depend on the quality.

I replaced the antifreeze yesterday, winter is still approaching. Before this, G11 was filled with something like Luxor green. This time I bought Hepu concentrate (G12+) and distilled water. At the same time I decided to change the thermostat to 92 degrees.

It is not difficult to drain the antifreeze; to do this, you need to unscrew the cap on the bottom of the radiator and the cap on the expansion tank. My radiator is from an old Nexia, there is a fitting for draining... however, when you unscrew the plug, antifreeze oozes from both the fitting and this plug) So you need a large diameter container to catch all this flow of antifreeze) For example, a basin will do). It is advisable to drain the antifreeze on a hot engine while the thermostat is open, this way much more will drain (you can wait 5 minutes after stopping and drain, the main thing is not to get burned). We wait for the antifreeze to drain, then remove the return hose from the expansion tank from the heating of the throttle body, and blow into it through a napkin (if you are squeamish, you can make some kind of device and blow with a compressor).

At the same time as purging, it is advisable to frequently compress and unclench thick radiator hoses. Quite a lot of antifreeze will drain out. According to my calculations, in this way it was possible to drain about 6.5 liters (with a capacity of 6.7 liters). Next, I poured plain water into the system, warmed up the engine until the thermostat opened ( before adding water or new antifreeze, the engine must cool down!

). After washing the engine with it, I drained it using the above method, then rinsed it again, but with distilled water. After that, I changed the thermostat (its housing on the N-150 is dismountable, it is very easy to change, the main thing is not to lose the gasket between the thermostat housing and the engine).

Then I poured in 3.5 liters of fresh concentrate and added distilled water to the required level. After that, I drove around, when the car cooled down, I added about 100 ml more water. That's all, I described the main points, everything else is a no brainer. By the way, on new radiator models (which come without a temperature sensor, I don’t know exactly which engines they are installed on), there is no drain fitting, there is just a plug located vertically.

How much antifreeze is poured into Nexia

We drain antifreeze using Daewoo Nexia 8 valves with our own hands

coolant directly affects both the engine operation process and the condition of the cooling system parts . pump, water jacket of the cylinder block, heater radiators and main radiator, thermostat. How Nexia This describes the process of replacing antifreeze in How much antifreeze. So it's a fake substitute for antifreeze

very weak. Now let's understand the process of replacing coolant for various Daewoo Nexia engines and choose the best antifreeze for replacement.

How much does antifreeze cost for a Daewoo Nexia engine?

Nexia N-100 engines is 6.2 liters.

Naturally, when replacing, sometimes you can drain the antifreeze to one hundred percent. In any case, about a liter of water remains in the system. Therefore, 5-5.5 liters is enough for replacement. Full volume of antifreeze

Valve cooling system Nexia N-150 16.
6.7 liters The situation is similar here. When replacing, some of the water remains in the system, so when replacing, approximately the same amount of water will be required. Find out how much antifreeze you need to pour into the radiator. But in immediate situations they can (and certainly will) occur when you need to add fluid to the usual level. That's when the new antifreeze .

Sometimes it is better to take a 10 liter canister than one can.

Replacement schedule

The fluid replacement procedure depends on its composition, engine operating conditions and the condition of the cooling system.

Nexia N-100
engines require replacement of silicate antifreeze (G11)
no later than two years of operation or 20 thousand mileage
More modern ethylene glycol and carboxylate fluids (G12 and higher) used in Nexia N-150 engines (16 valves), designed for a mileage of about 40 thousand km or 4 years of operation

Looks like very old coolant. it needs urgent replacement.

It should be understood that there are no ideal conditions, and the condition of the fluid should be monitored as often as possible. Antifreeze is close to losing its properties when:

the original color is lost, the liquid turns brown;
there is a visible oily film on the surface of the liquid in the expansion tank;
the liquid becomes cloudy, a foreign suspension appears;
foam is visible in the expansion tank;
The engine often overheats without heavy loads.

Change antifreeze on Daewoo Nexia

Distilled water (15 l), flushing and antifreeze (7 l). This kit is required if a slurry of unknown origin is found on the side of your vehicle.

The technology for replacing antifreeze with Nexia N-100 and N-150 is the same, only the difference in the volume of antifreeze , and even this is insignificant.

The work is best done at the opening of a voyage or inspection. When the thermostat bypass valve is open, the antifreeze must be drained, so the engine must be warm and the antifreeze. hot. This should be taken into account when emptying and protecting hands and clothing.

If the tank is dirty, don’t be lazy to remove it and wash it, then we assemble the system and fill in new antifreeze.

Choosing antifreeze for Daewoo Nexia

For a complete replacement of antifreeze

Any ethylene glycol based antifreeze can be used on Daewoo Nexia, as indicated by the G12 marking and carboxylate fluids (G12, G12, G13). To top up, it is better to use spilled antifreeze, and you should not rely on the color of the liquid. Each manufacturer adds its own additives, and they may not be compatible with other manufacturer's additives:

Blue Liqui Moly KFS 2000, recommended by officers;
red CoolElf Auto Supra;
Texaco Orange XLC DexCool;
yellow Volvo Coolant VCS;
pink GM Longlife;
red Hepu G12;
Blue-green Nissan Coolant L248 Premix.

Conclusion

Silicate-based antifreezes are acceptable, but their replacement should not exceed two years, while ethylene glycol and carboxylate compounds can last two to three times longer. . To replace antifreeze with your own hands, antifreeze is poured into antifreeze. Happy replacement and stable temperatures for your engines!

Cleaning the system

The author of the video made a mistake when he started adding a different type of antifreeze (G12+) to the old G11 coolant. In theory, coolants G11 and G12 are mixed with each other, but as a result, the new antifreeze loses a noticeable part of its original performance characteristics.

If you plan to switch from the original G11 antifreeze to G12, the circulation circuit of the Daewoo Nexia cooling system must be thoroughly flushed. To do this, use a special liquid to clean the antifreeze circulation channels. But if you don’t have such a remedy at hand, then you can try to get by with ordinary distilled water.

Pour distillate into the expansion tank . It is necessary to fill in the volume of liquid that came out during the draining process. As a rule, about 5 liters are poured.
Be sure to tighten the cap on the coolant tank.
We start the car and let the engine run until the forced cooling fan turns on.
We drain the flushing liquid by analogy with the scheme described above.
We repeat the washing procedure again.

How often should the coolant be changed?

The cooling system of an 8- or 16-valve Daewoo Nexia must be periodically filled with new refrigerant. Replacement intervals may vary slightly depending on the vehicle modification. You can read more about intervals in the service manual. Typically, the instructions indicate that replacement should be made after a mileage of 45 thousand kilometers or every three years.

Keep in mind that the service life of antifreeze directly depends on its characteristics. And also on the conditions of use, in particular, on the condition of the cooling system and the region in which the car is operated.

Signs of the need for urgent replacement

The following symptoms may indicate the need for an urgent change of antifreeze in the Daewoo Nexia:

Car enthusiast's recommendations

To ensure that your car lasts for a long time and there are no problems with operation, you should follow a few simple recommendations:

It is recommended to purchase antifreeze recommended by the manufacturer.
Carry out the cooling fluid replacement procedure only when the engine has completely cooled down.
Do not forget that any coolant is extremely toxic. Try to avoid getting it on the skin and mucous membranes.
After final assembly of the cooling system, check whether the expansion tank cap is tightly screwed on. Because the cooling system operates at a fairly high pressure and when starting the engine, a breakdown or leakage of fluid may occur due to a loose expansion tank cap.
If topping is necessary, do not use water. Antifreeze contains special chemical components that prevent the formation of scale and maintain normal operation of the cooling system with the help of additives included in the composition.
Check the system for leaks. Timely detection of liquid leakage from the cooling system will protect you and passengers in the cabin from toxic fumes.
If antifreeze gets on the mucous membranes, skin or painted parts of the car body, drink the area with copious amounts of water.
After replacing the fluid, discard the empty container. To avoid toxic particles getting into the air. Protect yourself and your loved ones. Useful tips
By periodically squeezing the radiator hoses, you will eliminate the possibility of air pockets in the cooling system.
If air does get into the system, the most effective way to eliminate it is to jack up the right side of the car. This will ensure that the throttle assembly fittings are positioned at the highest point of the system.
After replacing, do not forget to check the coolant level in the expansion tank after several days of operation. If necessary, add antifreeze to the system.

Try to buy coolant from well-known brands and trusted stores. Thus, you will significantly reduce the likelihood of buying a fake, which is quite easy to distinguish. The antifreeze does not contain a corrosion inhibitor. This additive is extremely important for all parts and components of the cooling system, reducing the aggressive properties of the liquid. If your antifreeze quickly discolors after replacement, drain the liquid immediately. High-quality antifreeze most often only becomes darker during use. A reddish or brownish color to the coolant can also be a sign of a poor quality product.

Don't forget to check for air lock in the system. When the engine is warm, wait until the temperature indicator appears, upon reaching which the fan should turn on. If it doesn't work, turn on the cabin heater. Check what air is flowing through the heater. Warm is a sign of a faulty fan, cold is a sign of an air lock. The last problem is easy to solve. Turn off the engine and wait for it to cool completely, after which you need to remove the cap from the expansion tank. Now start the engine and let it run for 5-7 minutes, then safely screw the cap back into place.

Coolant compatibility can be determined by specifications. There are no uniform production conditions, so most coolants, when mixed, change their properties not in favor of the automotive system. A universal way to solve the problem of topping up is to use distilled water.

How much antifreeze is in the engine of a Daewoo Nexia

The volume of the cooling system in the eight-valve Nexia N-100 engines is 6.2 liters.

Naturally, when replacing it is rarely possible to drain the antifreeze completely. In any case, about a liter of liquid will remain in the system. Therefore, 5-5.5 liters will be enough for replacement. The total volume of antifreeze in the cooling system Nexia N-150 16 valves is 6.7 l . The situation here is similar - when replacing, some of the liquid remains in the system, so when replacing, approximately the same amount of liquid will be required. However, in the future, situations may arise (and they will certainly arise) when it will be necessary to add fluid to the normal level. That's when the rest of the new antifreeze will come in handy.

Sometimes it is more profitable to take a 10-liter canister than to fill it with liter bottles.

Replacement Regulations

The schedule for replacing the fluid depends on its composition, engine operating conditions and the condition of the cooling system.

Under ideal conditions, when the liquid does not boil, does not become oily, does not oxidize, when the system is completely sealed, Nexia N-100 engines with silicate antifreeze (G11) require replacement no later than two years of operation or 20 thousand mileage .
More modern ethylene glycol and carboxylate fluids (G12 and higher), used in Nexia N-150 engines (16 valves), are designed for a mileage of about 40 thousand km or 4 years of operation .

This is what very old coolant looks like - it needs urgent replacement.

You need to understand that there are no ideal conditions and the condition of the liquid must be monitored as often as possible. Antifreeze is close to losing its properties when:

the original color is lost, the liquid becomes brown;
an oily film is visible on the surface of the liquid in the expansion tank;
the liquid becomes cloudy, a foreign suspension appears;
foam is visible in the expansion tank;
The engine often overheats without significant load.

It is unacceptable to force the engine to run with coolant that is not worn out, so at the first sign of the antifreeze losing its properties, we begin replacing it.

Daewoo Nexia N150 1.6l 16cl. › Logbook › Replacing coolant

Let me start with the fact that it was noticed that the antifreeze from the expansion tank decreased almost to the bottom. At that time, the coolant had been in the system for about 3.5 years, despite the low mileage of 21 because. After inspecting the cooling system, traces of leakage were found from under the reservoir cap itself and, as a result, on the reservoir itself as well. When I removed the lid I saw that one of its valves was standing on its edge and did not close, apparently it was leaking. Of course, I disassembled the entire lid, wiped it and put everything back in place. The decrease in antifreeze has stopped. Now the question of topping up naturally arose! Having scoured the Internet from selecting a suitable antifreeze to completely replacing it and taking into account the manufacturer’s regulations, I came to the conclusion that, in my opinion, it would be more reasonable to replace the coolant completely with flushing in two stages. In the first stage, we wash out the old coolant from the system with purified (distilled) water until clean water appears, fill in the flushing liquid and let it do its job, driving it in a circle with the engine running. In the second stage, we wash out the flushing fluid until clean water appears and add antifreeze concentrate to the system.

Stages of replacing Daewoo Nexia coolant

The process of replacing antifreeze is not labor-intensive, so it can be done independently. The operation is suitable for cars of different years of manufacture with 1.5-1.6 liter engines. In particular, this operation will be the same for:

Daewoo Nexia 8 valves
Daewoo Nexia 16 valves

Coolant drain

In this model, the liquid is drained only from the radiator, but it will not be possible to drain the antifreeze from the engine block on the Nexia; there is no drain plug for this purpose.

It should be noted that the antifreeze will be hot, so you should take care of your hands and clothes, after which we proceed directly to the procedure itself:

Open the hood and unscrew the expansion tank cap. This should be done slowly, turning the lid counterclockwise. This is done to eliminate vacuum in the system and reduce pressure.
To get to the drain valve, you need to unscrew the crankcase protection.
We open the tap located on the radiator on the right, but before that we install a container under it, because antifreeze should come from there.
If the tap is not equipped with a drainage tube, then after opening the liquid will begin to flow down the front beam and it is not a fact that it will end up in the container.
Some versions may not have a drain valve, so you will need to loosen the clamp from the lower radiator hose and remove it.
Remove the hose from the expansion tank and apply pressure to it to completely drain the liquid. This can be done using a household compressor connected to a battery, or try blowing into a hose.

This way, the maximum amount of old antifreeze will be drained, after which you can proceed to the next stage.

Leaks and problems

White smoke from the muffler or from under the hood, hot air from the stove instead of cold, engine overheating, a sweetish smell in the cabin - all this indicates that your Daewoo Nexia is leaking antifreeze or antifreeze.

The amount of refrigerant in the tank is constantly decreasing, even if all systems are working properly. You should worry if the process is much faster than usual. There are several reasons for this:

The expansion tank or plug is damaged. Visually check the tank and lid for cracks, abrasions, or chips so you can spot the problem early and replace them.
Radiator pipes are leaking. This happens either at the joints or due to damage. Loose fasteners cause antifreeze to leak out of the pipes. Leave the car for a day, placing a piece of cardboard under it, and you will definitely find out about the problem.
Faulty heater radiator. An oily puddle under the front passenger seat and fogging of the front window may indicate a problem with the radiator.

Be sure to check all pipe connections; moisture at the connection points indicates a leak. To correct the situation, most often it is enough to replace the clamps or gaskets.

It's much worse if:

Liquid will enter the engine. A white coating on the spark plugs will indicate a problem that you should not try to solve yourself, but it is better to immediately contact the service center.
There will be a leak into the oil. The situation can be diagnosed by white smoke from the exhaust pipe and deposits on the oil dipstick.

Problems can also be observed in the cooling system itself:

A long time to reach operating temperature, overheating or elevated temperature indicate a malfunction of the thermostat, which must be replaced as an assembly.
Sometimes the fan or its switching sensor fails.
Pump problems are usually caused by a bearing or a burnt winding (if it's electric).

Coolant replacement procedure

According to the technical documentation on Daewoo Nexia cars, a planned replacement of the internal combustion engine cooling should be carried out after 2 years of operation or every 40,000 km.

Every car owner can easily replace the coolant, only for this he needs:

clean rags;
new coolant;
pliers;
container for liquid.

The replacement procedure itself consists of the following points:

Raise the car on a lift or drive it into a viewing hole.
Unscrew the cap from the expansion tank.
Drain the old coolant. To do this, you need to unscrew the tap at the bottom of the radiator on the right side. Do not forget to place a previously prepared container under the drain hole.

You can replace the antifreeze in a Daewoo Nexia at a car dealership, but the process is simple and won’t take much time, so you can do it yourself.

Step-by-step instructions for draining old fluid from the tank:

The car is driven into a pit or onto an overpass to make it more convenient for the owner to work. To drain all the liquid from the cooling system, the engine must be warmed up, thus opening the thermostat valve. After warming up, the car is placed on a jack on the left side of the front wheel;
The hood of the car opens. The car owner finds the tank he needs and unscrews the cap;
Then you need to find the crankcase under the car and, using wrenches, unscrew the fixing bolts from its protection;
During this entire procedure, the car’s engine will cool down a little, the main thing is to make sure that it does not cool down completely. When the engine is warm, open the heater valve. Don’t be afraid, a little antifreeze will spill out of it, so you should substitute the container in advance;
Next, you need to unscrew the drain plug on the radiator and place a wide container prepared in advance so that the waste liquid flows into it. In Daewoo Nexia, the tap is not very conveniently located, so the coolant will flow down the body. If the car owner completely changed the radiator, then there is a possibility that there will be no tap on it. In this case, you will have to disconnect the hose from the system and pump the used antifreeze directly from it into a container.

Step-by-step instructions for flushing the cooling system in a car:

In order to properly replace antifreeze, the cooling system should be completely flushed, which many drivers do not do because they do not consider it necessary. The first thing you need to do is screw the valve back on the stove and radiator;
Distilled water is poured into the antifreeze tank. Usually you can use about 6-7 liters, the main thing is that the level reaches the minimum mark. It should be remembered that the cooling system should be cleaned only with distillate, otherwise tubes, hoses and valves may be damaged;
The tank cap is screwed in, after which the engine starts and the cooling system turns on. Thus, the distillate is driven through all elements of the mechanism;
The system should work for about 5 minutes, the water level should decrease, which means that all the air has escaped;
Next, exactly as described above, drain the distilled water from the system. If the car owner sees that the water has the color of antifreeze, a pungent odor or a dark sediment, it means that not everything has been washed yet and the procedure should be repeated several more times. Only after clear liquid has flowed out of the car can this stage be considered completed.

The refrigerant is filled as follows:

All valves and taps are tightened, the radiator pipe is attached to its place;
Antifreeze is poured into the expansion tank to a level between the MAX and MIN marks;
The plug is tightened, then a control trip is carried out. You should drive for about 5 minutes and open the hood again and unscrew the plug;
The air accumulated when filling in the refrigerant had to come out during the trip, which means the liquid level in the tank has decreased, it needs to be topped up.

The procedure should not take the performer more than 30 minutes, since the Daewoo Nexia is an easy-to-maintain car. The technical arrangement of parts and spare parts is designed in such a way as to make servicing the machine as easy as possible.

8 valves

An important element when replacing the refrigerant in the described car is the number of engine valves, since due to the different number of valves, the volume of liquid being filled also differs. When replacing antifreeze on a Daewoo Nexia with 8 valves, about 6.2 liters of refrigerant are poured into the tank.

Volume varies due to engine power. If a car has 16 valves, it will accordingly need more cooling, since it will consume more energy.

16 valves

When replacing antifreeze in a Nexia with 16 valves, about 6.7 liters of refrigerant are used. The differences between replacement with a 16-valve and 8-valve engine are only in volume, otherwise the procedure and process are completely the same. The main thing when planning work, when purchasing antifreeze, is to know which engine is in the car in order to buy the appropriate and necessary volume of coolant.

Preparing for work

Before draining antifreeze from the Daewoo Nexia block, you should determine the volume of liquid. The coolant level can be determined by eye by diagnosing the amount of antifreeze in the tank. Open the hood and look into the reservoir in which the antifreeze is stored. The tank is marked with MIN and MAX marks. If the liquid level is between these marks, then the volume of refrigerant is optimal. You should not check the amount of fluid while the car is running with a hot engine, as the coolant level will be higher.

To change the fluid in the Daewoo Nexia, the car owner will need the following tools:

Purchased or old rags;
Regular pliers;
A wide container where old antifreeze from the tank will drain. It is better to choose a wide reservoir, since in case of a leak or if antifreeze spills due to carelessness, it will fall into the container. Car owners choose cans.

You should take care of your own safety. Turn off the car engine, put on gloves and cover your eyes with plastic glasses. Car owners rarely adhere to safety precautions, but antifreeze is a chemical and if it gets on the cornea of the eye, you can lose your vision. Take care of your own health and follow safety precautions even in such small things.

How often does antifreeze need to be changed in Daewoo Nexia?

When operating a Daewoo Nexia car, antifreeze should be periodically added to the tank without replacement or cleaning procedures, since these models have a powerful engine that requires constant cooling. Over time, the level drops and to avoid major and costly breakdowns, you need to check it once a month.

However, the operating instructions provide information that every three years or every 45 thousand kilometers the antifreeze on the Daewoo Nexia must be replaced. These deadlines were not calculated by car developers and manufacturers by chance. The optimal mileage and time are calculated under ideal driving and environmental conditions that affect the antifreeze and cooling system. Even in the best conditions, replacement is required after 45,000 km.

To properly replace antifreeze in this car in Russia, it is important to remember about environmental pollution, aggressive driving and bad roads in the country. Thus, the optimal solution would be to change the antifreeze every year.

Timing drive of Nexia 1.5 l engine.

The camshaft of the Nexia's 8-valve engine is driven by a toothed belt from the crankshaft. The valves are actuated by the camshaft cams through pressure levers, which rest on the hydraulic lash compensators with one shoulder, and on the valve stems with the other shoulder through guide washers. The engine has hydraulic compensators

, which are self-adjusting support levers. Under the influence of oil filling the internal cavity of the compensator under pressure, the compensator plunger selects a gap in the valve drive. The use of hydraulic compensators in the valve drive reduces the noise of the gas distribution mechanism and also eliminates its maintenance.

If the belt breaks, the valve bends!

Among other features, it can be noted that the timing belt rotates the pump (water pump). The belt is replaced every 60 thousand kilometers, the pump must be changed every 120 thousand kilometers. Please note that on the old 8-valve engine with 75 hp. The timing belt generally changes every 40 thousand kilometers.

Engine characteristics Nexia 8 valves 80 hp

A fairly reliable and unpretentious engine, the main thing is to change the oil, timing belt, and pump on time. A completely repairable power unit. The best option for a budget car.

Daewoo Nexia is one of the few cars that have been seen on domestic roads for more than 20 years. Its prototype was the popular Opel Kadett sedan, modernized in 1995. Over the years, the Daewoo Nexia engine was represented by the following models:
