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:

When to change antifreeze and what is in there from the factory

Car manufacturers are cunning people, they save on everything so that the output price of the car is as low as possible. The same applies to coolants. Depending on the assembly plant and year of manufacture, the Nexia’s cooling system could be filled with Aga Z65

Green colour.
Nevertheless, the plant officially recommends pouring Liqui Moly KFS 2000
with blue dye. So what is it? Why confuse people?

If the tank of your car is filled with green coolant, this does not mean at all that you can add any antifreeze of the same color.

The fact is that the color of antifreeze does not affect its composition in any way and manufacturers of technical fluids have the right to add any dye. Antifreeze is initially transparent, and is colored in order to identify leaks and differentiate by manufacturer and only in rare cases by chemical composition. Daewoo officially says that it allows the use of liquids only based on ethylene glycol. And what color it will be does not play a key role.

When should you change it?

Replacing antifreeze is much easier. The manufacturer says that the coolant needs to be changed at least once every 40,000 km or after two years of operation.

However, the mileage before replacement depends on the quality of the fluid, operating conditions, and the condition of the engine. The first signs indicating that it is time to change the fluid are cloudiness, loss of color, oiling.

Purpose of antifreeze

There is nothing difficult about completely draining the coolant from the car system. But before starting this process, you need to familiarize yourself with the structure and operating principles of the system as a whole.

Antifreeze and antifreeze mean non-freezing technical fluid used in the car system not only to cool the engine and other units, regardless of climatic conditions, but also to lubricate certain elements and protect them from corrosive changes. Like all other technical fluids in a car, antifreeze deteriorates over time and loses its properties, which means that this material must be regularly replaced.

According to the rules, it is recommended to change the coolant at least once every three years, however, these dates may shift depending on how intensively the vehicle is used. If you constantly neglect this simple rule, then the recycled liquid will cease to function fully. The consequence of this will be constant overheating of the engine and all adjacent systems, as well as the appearance of corrosion.

Some craftsmen, in order to save money, dilute antifreeze with water, without even suspecting the serious damage they thereby cause to their own car. Thus, adding water causes the pump to jam, which does not receive the required amount of lubricant, as a result of which the belt may break or the gear teeth may be damaged. As a result, the distribution valves and the entire piston system as a whole may fail, so the decision to add water to the antifreeze is clearly wrong, and its consequences can be extremely disastrous.

Changing antifreeze on Daewoo Nexia

Distilled water (15 l), flushing and antifreeze itself (7 l) - this kit will be needed if there is a liquid of unknown origin in the tank of your car.

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

It is better to carry out the work on an overpass or inspection hole. Antifreeze must be drained when the thermostat bypass valve is open, therefore, the engine must be warm and the antifreeze will be hot. You need to take this into account when draining and take care of your hands and clothes.

Remove the expansion tank cap.

Unscrew the expansion tank cap.

Don't forget to open the stove on the control unit.

We find and open the tap at the bottom of the radiator.

We drain the old antifreeze.

If you have a compressor, connect it to this hose.

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

Choosing antifreeze for Daewoo Nexia

To completely replace antifreeze with a Daewoo Nexia, you can use any ethylene glycol-based antifreeze, as indicated by the G12 marking and carboxylate liquids (G12+, G12++, G13). For topping up, it is better to use exactly the antifreeze that was filled in, and you should not rely on the color of the liquid - each manufacturer adds its own additives and they may not be compatible with additives from another manufacturer:

• blue Liqui Moly KFS 2000, which is recommended by the officials;
• red CoolElf Auto Supra;
• orange Texaco XLC DexCool;
• yellow Volvo Coolant VCS;
• pink GM Longlife;
• red Hepu G12;
• blue-green Nissan Coolant L248 Premix.

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.

Replacing coolant Nexia 8 cl

Useful tips By periodically squeezing the radiator hoses, you will eliminate the possibility of air locks 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 a minute, 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.

After the work done, you need to evaluate the remaining fluid to determine the number of Daewoo Nexia coolant replacement 8 valve solution and calculate the volume if a concentrate is used. If necessary, the system is flushed with distilled water. First, fill the tank with water, turn on the motor and run it until the cryostat tap opens, when water flows out in a large circle.

A little history and chemistry

Initially, cooling systems used the most accessible liquid - water. However, it has many disadvantages: both the need for preparation to avoid scale formation and too high a freezing temperature. As a result, in winter, when parking the car for a long time, it was necessary to drain the coolant system and refill it before leaving.

A solution to the problem was found in the use of coolants with a lower freezing point, mainly ethylene glycol. Its 60% solution in water froze already at -49 degrees, which was more than enough. But another question immediately arose: in addition to toxicity, ethylene glycol-based coolants are also highly corrosive. That's why:

Antifreeze contains corrosion inhibitors that prevent the destruction of cooling system parts.

Unfortunately, such an additive package does not last forever, and antifreeze that has worked for several years is chemically much more active than fresh one. Hence the need to regularly replace the coolant. Moreover, its service life depends on the class: for example, G11 antifreeze (usually green) contains fewer additives than traditionally red G12 and ages faster.

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 to check the level correctly?

Checking the refrigerant level is carried out visually by diagnosing the amount of liquid in the expansion tank. Open the hood and take a look at the reservoir. Ideally, the antifreeze level in the Daewoo Nexia should be between the MIN and MAX marks. Diagnostics are performed only on a cold engine. On a hot power unit, the coolant level in the tank will be higher.

Required amount

Before replacing, you need to know how many liters are poured into the cooling system of the Nexia 150 2012 or another year of manufacture. The volume depends on the engine modification.

Please note that it will not be possible to completely drain the substance from the cooling system. There will be about one liter of liquid left in it. It can be removed by blowing with compressed air.

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:

1. 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.

2. To get to the drain valve, you need to unscrew the crankcase protection.
3. 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.

4. 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.
5. Some versions may not have a drain valve, so you will need to loosen the clamp from the lower radiator hose and remove it.

6. 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.

Flushing the cooling system

After the fluid has been drained from the Daewoo Nexia, evaluate its condition; if the drained antifreeze is of normal color, then you can start filling in new ones. And if there are deposits or suspended matter there, then the optimal solution would be to flush the system:

1. Close the valve on the radiator drain hole.
2. Fill the expansion tank with distilled water (or a special product, if available). Fill to the level of the lower mark on the tank (the whole thing will take about 6-7 liters). Under no circumstances should you rinse with regular tap water!

3. We tighten the tank cap and start the engine.
4. As soon as the internal combustion engine starts, the fluid level may drop. This is the result of removing air from the system.
5. The water begins to flow in a large circle after a few minutes of operation, after the thermostat opens.
6. After this, turn off the engine and drain the water.
7. We evaluate the cleanliness of the drained liquid and, if necessary, repeat the process again until it is completely cleaned.

Filling without air pockets

In order to start filling in new antifreeze, you need to check the closed tap on the radiator and connect the pipe to the expansion tank. You can put the engine protection in place.

1. If the fill is done after flushing the system, then the best option would be to use a concentrate. It is worth diluting taking into account the remaining distilled water in the engine that cannot be drained. You need to fill through the expansion tank to a level between o and “MAX”.
2. Screw the cap on the filler neck and start the engine.
3. Warm up at idle until the thermostat opens and the cooling fan turns on.
4. We carefully inspect everything for possible leaks, pay attention to the fluid level. If necessary, top up to the level.

Draining procedure

If you don’t want to overpay for a car service center, but don’t have practical experience in how to drain coolant from an engine, then you can check out the master class on replacing antifreeze using the example of a VAZ-2114 car. First of all, it is necessary to carry out certain preparatory manipulations, which include:

1. Placing the car on the platform, since ideally it should be in a horizontal position.
2. Waiting for a certain time necessary so that the motor and the liquid in it can cool down and not cause burns to the novice master. Even opening the cap of the expansion tank or any other unit can trigger the release of scalding antifreeze steam with all the ensuing consequences.
3. Study of the system design and location of antifreeze drain points.

The fact is that not every inexperienced technician will be able to immediately determine where the coolant drain plug is located in his car. The designs of this system may vary depending on the make of the vehicle. Most often it is located at the very bottom of the radiator or in the pipes extending from it.

The presence of a special drain plug, which is not provided in all designs, is of great importance for the process of draining used technical fluid. And if it is not there, then the antifreeze is released from the main engine block by disconnecting the lowest pipe from the radiator. This is how the antifreeze is drained from the cooling system, after which it must be thoroughly rinsed with distilled water to prevent the development of possible problems due to potential incompatibility of technical fluids from different manufacturers.

Sometimes, in order to completely drain antifreeze from the system, it is necessary to resort to additional manipulations. The process of cleaning the radiator and engine block will be performed as follows:

1. After the recycled liquid comes out on its own, the drain hole is left open and the expansion tank cap is closed. Then turn on the stove at full power and start the engine. In this way, it will be possible to create additional pressure in the system, thanks to which the antifreeze will come out even from the most inaccessible places.
2. The engine is turned off literally after a few minutes, since its operation without coolant can lead to overheating of the elements and, as a result, to their deformation and damage. If antifreeze continues to drip from the drain or radiator hole after disconnecting the pipe, then the procedure must be repeated when the car has completely cooled down.
3. An indicator for monitoring the degree of cleaning of the vehicle cooling system is the presence of released antifreeze drops. Their absence should be regarded as a sure sign that the antifreeze has been completely drained.

Having figured out how to drain coolant, it doesn’t hurt to familiarize yourself with the basic rules for adding it.

Replacing antifreeze with Nexia

The maintenance schedule recommends replacing the coolant every 40,000 km, but preferably at least once every 2-3 years.

Fill with antifreeze. We put on the throttle heating hose after the antifreeze starts flowing.

I installed new clamps (8-12, 10-16, 16-25).

We drive the car up the hill in front, do a good gas release for 3-5 minutes, expelling the air from the system.

After replacing the antifreeze with a new one, the stove began to heat up noticeably hotter

#8 aleksey_taraban 06.22.2017 19:56 Every 2-3 years (40,000 km) replace antifreeze!? What nonsense!? I changed the timing belt 60,000 km, 120,000 km changed the timing belt, pump, thermostat and antifreeze (8 klp )!And the fact that in the photo there is not even a difference in color, there is more antifreeze in a cut-off canister than in a cut-off bottle, which is why the color is darker. And at 120,000 km I had a red color, although the properties were the same. And in the cold it started in the summer. KHMAO. I removed the pump and the antifreeze flowed out on its own and there is no need to blow it somewhere (use a compressor).

#7 valeraf 03.28.2017 19:51 Hello dear friends! Let me tell you about one very interesting site, I would like to recommend you a very interesting site about a store of ready-made curtains for the home. I ordered here myself, and you know, they are perfect! Here is the website https://tomdom.ru/

#6 Lan 10.23.2016 14:13 I installed a tube in the throttle return, as shown on the website, I think it’s effective because When circulating, the liquid loses its waterfall effect and the flow of liquid into the heater radiator increases

#5 Redactor 10.12.2016 22:17 Quoting Nemesis:

Tell me another thing, when filling in antifreeze, I immediately put the throttle heating hose on the expansion tank, without waiting for antifreeze to leak from there. Is this not necessary, or is it better to drain and refill?

It's OK. After starting the engine, unscrew the expansion tank cap and check for circulation in the tank. if circulation is present, then everything is in order.

#4 Nemesis 10.12.2016 17:21 Tell me another point, when filling in antifreeze, I immediately put the throttle heating hose on the expansion tank, without waiting for antifreeze to leak from there. Is this not necessary, or is it better to drain and refill?

#3 Redactor 10/12/2016 15:40 Quoting Nemesis:

I changed it that way too, who can tell me on the N150 1.6 at what temperature the fan turns on and at what temperature it turns off. And is my system working correctly? The fan turns on at 97 degrees and turns off at 93 degrees. Is that how it should be?

depends on the firmware.

We drive the front of the car up the hill, thereby lifting the front.

An absolutely unnecessary procedure. a working pump will expel the air on its own. 30-40 seconds of gas is enough.

#2 grezko 10/12/2016 07:36 Quote:

We set the heating mode switch to the hottest position, thereby giving the opportunity for antifreeze to drain from the heater radiator

Nexia is not Volga. The switch controls the air damper, not the valve. Therefore, it does not matter at all what position he will be in.

#1 Nemesis 10/11/2016 10:24 pm I also changed it this way, can anyone tell me on the N150 1.6 the fan turns on at what temperature and at what temperature it turns off. And is my system working correctly? The fan turns on at 97 degrees and turns off at 93 degrees. Is that how it should be?

1. Radiator of the heating system, for warming up the air and blowing inside the glass in the car interior.
2. An air blower into the car interior, which is a classic electric motor equipped with an impeller. The component regulates the air flow to the dampers of the heating system or air conditioning unit.
3. The damper of the thermoregulation mechanism, which regulates air flow through the radiator.
4. A special execution system that controls and separates air flows.
5. Control rod, pipe, air lines, hoses.

Preparing to replace the heater core

Stove failure may be due to specific reasons. Its incorrect operation may be associated with a malfunction of either one part or several parts at the same time. The stove may break down for the following reasons:

1. Poor circulation of coolant due to clogging of the heater radiator channels with dirt particles.
2. Coolant leak in the heating system mechanism.

To correct this situation, it is necessary to clean or replace the broken radiator of the Daewoo Nexia stove, which is a rather complicated process.

In order to save time, it is recommended to mark existing harnesses and wires.

Replacing a radiator consists of operations in which:

1. The car is installed on an overpass or inspection hole.
2. Electrical power from the battery is disconnected by disconnecting the negative terminal.
3. The protection from the engine is removed, allowing for more access to the radiator.
4. Drain the coolant from the coolant system.

Next, you can dismantle the heat exchanger by disassembling the central panel of the car and removing the tightening clamps and hoses.

What models of radiators can be installed on Daewoo Nexia

As numerous car owners note, a factory-installed radiator does not in all cases effectively heat the car interior during cold periods.

To ensure the required temperature level in the car showroom and more comfortable operating conditions, you can install other radiators in the car.

You can replace the factory radiator in three different ways, using the radiator of the Luzar, Daewoo Lanos or VAZ-2106 model.

Radiators are classified according to various criteria, one of which is the manufacturing model. So, according to this criterion, radiators are:

• Copper radiators, with typical properties and high cost;
• Brass radiators;
• Aluminum radiators, which are the cheapest.

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:

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.

Problems can also be observed in the cooling system itself:

How to change antifreeze on Nexia?

And what color it will be does not play a key role. When should you change it? Replacing antifreeze is much easier.

The manufacturer says that the coolant needs to be changed at least once every 40 km or after two years of operation. However, the mileage before replacement depends on the quality of the fluid, operating conditions, and the condition of the engine.

Self-replacement of antifreeze on Daewoo Nexia

The first signs indicating that it is time to change the fluid are cloudiness, loss of color, oiling. Choosing antifreeze for Daewoo Nexia - which one is better? Economy class antifreeze. The best way to replace coolant in a Daewoo Nexia is on an overpass or in a garage with a pit. It is advisable to warm up the engine to operating temperature in advance so that the thermostat valve opens. For the best effect, you need to place the left side of the body on a jack somewhere in the area of ​​the front wheel.

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 cap of the expansion tank.

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 coolant protection on the Daewoo Nexia. 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.

How to add antifreeze

Re-adding coolant to the expansion tank and the system as a whole is also not difficult, but nevertheless there is a certain procedure that should not be violated. It involves performing the following manipulations:

1. Opening the expansion tank cap and adding antifreeze to the maximum level.
2. Closing the tank lid, turning on the car's heater at full power and starting the engine. After this, all vehicle systems are started, including the cooling system. The liquid from the tank should fill its elements.
3. As soon as the antifreeze level in the tank drops to the minimum level, the engine is switched off, and the level is replenished again to the maximum. The procedure is repeated several times until the technician sees that the antifreeze stops leaving the system and its level remains the same.
4. After a few days of active use, a control test is carried out, and if the level of antifreeze in the tank drops again, it must be replenished.

The next replacement of antifreeze is recommended after three years or after 60 thousand kilometers. The main thing is to do it correctly.
