How to drain coolant on a VAZ-2114: photo of draining antifreeze
Many motorists at car repair shops have seen how the coolant on VAZ-2114 cars is completely drained, but have not done it themselves. There are several factors that influence why you need to perform this operation. So, in this article we will look at how and why it is necessary to completely drain the coolant.

Cooling system elements
The process of draining coolant from the radiator
In order to understand how and why it is necessary to drain the coolant, you need to have a little understanding of the design of the car and the cooling elements. Also, you need to know how the coolant circulates in the engine and have an idea of the places where it can be drained.
So, let's look at the complete diagram of the engine cooling system and how the coolant circulates:

Coolant drain options
There are two options for draining coolant from the system. They depend on what operations the motorist intends to perform with the car. So, let's look at both options separately.
Draining without removing the engine
This method is often used to replace coolant in the system, as well as to change cooling elements. The procedure is quite simple. Let's look at how to properly drain the liquid from the cooling system completely:
- We find the cooling system plug on the cylinder block.
Location of the coolant drain plug on the cylinder block
- Unscrew the expansion tank cap.
Remove the expansion tank cap
- Having previously placed the container, unscrew the plug on the cylinder block.
- When all the liquid has drained from the power unit, unscrew the plug, which is located in the lower right part of the radiator.
Unscrew the plug on the radiator to drain the coolant
- When all the liquid has flowed out of the radiator, you need to tighten the plug on it and on the block.
- Fill in new coolant.
Installation of faucet
Drain faucet
For the convenience of subsequent draining and repair work, you can install a faucet. Moreover, you have already unscrewed the standard plug.
Draining with engine removal
The second method is easier than the first and is used when the engine is planned to be removed. Let's consider the sequence of actions aimed at draining coolant from the system:
- Unscrew the plug on the expansion tank.
- We unscrew the plugs from the cylinder block and radiator.
- Next, when the liquid has flowed out, you need to unscrew the pipes leading to the radiator.
- Of course, some liquid remains in the system and must be drained completely. This can be done in two ways: by blowing it out with a compressor or by disassembling the engine.
Why do you need to drain the coolant?
This “slurry” has already served its term
Let's look at the main reasons why you will need to completely drain the coolant from the system:
- Development of a full resource of use . It is recommended to carry out once every 90-100 thousand km. This is due to the fact that the coolant, due to a constant temperature difference, which is its operating temperature, loses its technical and physicochemical properties. After such a mileage, it can no longer effectively provide cooling of the engine and its elements, which can lead not only to failure of the thermostat and pump (most often these are the spare parts that suffer), but also to boiling of the engine, which can have unpleasant and material consequences .
- During engine overhaul . When the engine is dismantled for major repairs, the coolant will need to be completely drained.
- Replacing the radiator will also require draining the coolant completely from the system, but it is done according to a simplified option (the second one, which is indicated above).
- Replacement of other individual elements that will require draining the coolant from the system.
Conclusion
Draining the coolant completely from the VAZ-2114 is quite simple. This procedure does not require any special skills or tools. So, almost every car owner can perform this operation. But, if a car enthusiast is not confident in his abilities, it is recommended to contact a car service center, where everything will be done quickly and efficiently.

Frequency of antifreeze replacement
Publication date: April 11, 2016.
Antifreeze or antifreeze is used in the cooling system of every car.
Regardless of whether the liquid is based on ethylene glycol or propylene glycol, it contains a proportion of water and additional additives that have antioxidant, antifoaming and other properties.
After the aging of the coolant, the coolant must be replaced, since some of the coolant elements lose their characteristics.
The car's operating instructions contain recommendations for replacing antifreeze, but there are also generally accepted rules that will help you figure out how to fill in antifreeze correctly. First of all, let's look at the frequency of coolant replacement.
How often does antifreeze need to be changed?
Most manuals for car enthusiasts say that antifreeze needs to be changed every 40-45 thousand kilometers. But, in fact, in this matter you need to start from the type of coolant and its classification. For example:
- Class G 11 fluids, intended for cars manufactured before 1996, have a short shelf life of 2-3 years.
- Antifreeze G 12, recommended for cars manufactured from 1996 to 2001, will last longer - 5 years.
- Coolant G 12+, which is used for cars manufactured after 2001, also has a five-year shelf life.
- Liquids G 12++ and G 13 are rarely used in the domestic automotive industry, but they also have a long shelf life.
Healthy! If you mix different types of refrigerants with the same base, then their shelf life is automatically reduced to 2-3 years.
As you can see, a lot depends on the class of the coolant, as well as on the base on which the liquid was made. Ethylene glycol is toxic and takes a long time to decompose, resulting in corrosion on parts of the cooling system.
Therefore, it is recommended to change refrigerants of this type more often. Propylene glycol is considered an environmentally friendly product that quickly decomposes, which is why it lasts longer.
Therefore, the fluid replacement period can range from 40,000 to 200,000 kilometers.
To determine when it’s time to change the antifreeze, just purchase a special test strip, which you will find at any auto parts store. Another option is to look at the service book of your car; the coolant replacement period must be indicated there.
To replace antifreeze, you need to prepare everything you need: “fresh” liquid, distilled water for rinsing, gloves, a filling funnel and a container for draining. After this, you need to drain the old coolant.
How to drain antifreeze
To make a replacement according to all the rules, it is necessary to drain the antifreeze from the engine, radiator and heating system of the car interior.
To do this, you need to drive the car onto a slope, a hole, or use a jack, so that the front of the car is raised.
Next, you must wait until the car engine cools down so as not to get burned. After this, perform the following manipulations:
- Unscrew the cap of the expansion tank. In this case, it must be smoothly turned counterclockwise until it stops in order to relieve the residual pressure in the system. You can then remove the cover completely.
- Place a prepared container for draining under the drain plug (on different car models it can be located both on the engine and on the radiator). Then open the drain valve located at the bottom of the radiator and drain the old coolant.
- Close the drain valves and fill the system with clean distilled water. It is important to remember that you cannot pour cold water into a hot engine.
- Tighten all the plugs, but leave the expansion tank open.
- Run the engine for 5-10 minutes to flush the cooling system. In this case, all heating devices in the car must operate at maximum power.
- Drain the water and repeat this step until the drained liquid is clear and clear. For flushing, you can also use specialized flushing compounds.
After this, you can tighten the drain bolt and move on to the next step.
How to pour antifreeze into the cooling system
In order to fill in new antifreeze, the car can be removed from the jack, but before doing this, be sure to check how securely the drain bolt is tightened.
Before pouring antifreeze into the car, make sure that the cooling system is sealed, all elements are intact and functioning properly. Depending on the time of year, the coolant can be diluted with water to varying degrees. After that, follow these steps:
- Remove the cap from the expansion tank filler neck.
- Very slowly, start pouring coolant in a thin stream.
- Different car models require different amounts of antifreeze. In order not to “miss”, pay attention to the translucent wall of the expansion tank, on which there is a “MAX” mark. She will just tell you how much antifreeze to fill.
- Screw the filler cap tightly.
- Start the engine and warm up the car to standard operating temperature. First, the fan of the car’s cooling system will start working, and as soon as it turns off, this will indicate that the temperature has reached its normal level.
- Turn off the engine and wait until it cools down completely.
- Check that there is enough antifreeze in the tank. If the fluid level has dropped, add coolant to the required level.
This is a standard procedure for draining and replacing antifreeze, but before any manipulations, be sure to refer to the car manufacturer’s recommendations. In some situations, antifreeze is poured into both the expansion tank and the radiator neck.
Other car models are equipped with non-separable radiators and therefore liquid can only be poured into the tank.
In addition, some car enthusiasts often confuse the expansion tank and the washer, so be sure to take into account the possible design features of your car and follow the following tips.
Precautions and Tips
When replacing antifreeze, the following recommendations and warnings will help you:
- When deciding how much antifreeze you need, keep in mind that the liquid level in the radiator must reach the lower edge of the neck (if coolant is poured into it).
- When working with antifreeze, be extremely careful and fill it away from children. It is advisable to do everything in the fresh air to inhale as little ethylene glycol vapor as possible.
- If liquid gets into an open area of the body, into the eyes or other mucous membranes, immediately wash the area with clean water.
- Do not allow antifreeze splashes to get on the painted parts of the car body. Especially if you use a liquid with added silicates or based on aggressive ethylene glycol. If coolant gets in, it can corrode the paint, so if this happens, wash the surface with plenty of water.
- The toxic components of the liquid are dangerous to the lives of people and animals, so always close the container with the composition.
- If you use the same antifreeze from the same manufacturer, then flushing the cooling system is not necessary. This procedure is only important when switching to a different type of coolant.
- If you are using a concentrate rather than a ready-made liquid, remember the proportions. In summer, you can add more water to the composition (1:1), since in the heat it will evaporate faster. In winter, you cannot add so much water, as under the influence of low temperatures this will lead to freezing of the liquid. As a result, the expansion tank may burst.
In custody
Before changing any fluid in a vehicle, be it motor oil or antifreeze, be sure to consider the composition of the fluid, which must meet the requirements of your vehicle. A poor-quality or inappropriate product can lead to rapid wear of parts and subsequent costly repairs.

How to drain antifreeze from the engine block
For long-term and efficient operation of vehicle systems that use fluids, they must be changed periodically.
The technical documentation of the car does not always indicate the requirements for when and what needs to be replaced; you yourself must understand that there is a limited service life.
When any mechanical system operates, rubber peeling, microparticles of metal shavings and other debris form over time. This is why you should sometimes replace all fluids. Antifreeze, a liquid for the engine cooling system, is no exception.
In addition to maintaining the temperature at the required level, this type of liquid takes part in warming up the radiator of the interior heating system. When circulating through the system, antifreeze is involved in lubricating the parts of the cooling system pump, and also prevents the formation of rust.
1
When to drain antifreeze from the engine block
Replacing antifreeze or antifreeze with your own hands will not be a problem for the average car enthusiast. It is necessary to drain the liquid in the following cases:
- Before replacing the car radiator.
- When replacing coolant seasonally.
- When installing a new thermostat.
This system is carried out in 2 stages, since the liquid is contained in the radiator and in the engine cooling system.
2
How to drain antifreeze from the engine block - stage 1
Before pouring new fluid into the cooling system, it is necessary to drain the old one. Let's figure out how antifreeze is drained. To drain the working fluid, most cars have a drain plug installed in the cooling system.
It is installed at the lowest point of the system, on one of the lower corners of the radiator. The drain plug may not be provided on some car models. In such cases, in order to drain the old fluid, it is necessary to disconnect one of the cooling system pipes connected to the radiator.
Please note that under no circumstances should you drain antifreeze on a hot engine. When a liquid is heated, it expands, which means the pressure inside the system rises.
For what? High pressure prevents the evaporation of liquid in the system.
If you remove the hose or open the drain plug in such a situation, the pressure in the system will become equal to atmospheric pressure, which will lead to the formation of a powerful jet of steam.
Only after the engine has completely cooled down can the fluid be drained. Unscrew the cap located on the expansion tank of the cooling system. Open the drain plug or disconnect the pipe.
Wait until all the antifreeze has drained out. Please note that a certain amount of liquid is located below the level of the drain hole (interior heating radiator).
Without additional operations, you will not be able to remove this liquid from the cooling system.
3
How to drain antifreeze from the engine block - stage 2
To drain any remaining coolant, follow these steps:
- Using a spanner, unscrew the drain plug, which is located under the ignition unit.
- Wait about 10 minutes for the antifreeze to drain.
- Wipe the plug and assess the condition of the seals. If necessary, replace them and tighten the cap.
Please note that antifreeze is an active chemical. It has a sweetish smell that may attract pets or children! It must be poured into tightly closed containers. It is strictly not recommended to simply drain onto the ground.
4
Filling with new coolant
Only after the old antifreeze has been completely drained can you begin to fill in the new one. The manufacturer and brand of the substance must comply with the vehicle manufacturer's recommendations. The use of additional additives may negatively affect the formation of rust in the radiator or cylinder block.
The level of the filled antifreeze should be between the min and max marks on the expansion tank. After replacing antifreeze, air pockets may form. To get rid of them, you need to slightly loosen the pipe clamp.
Coolant must be added carefully and gradually. After completing all the work, start the engine and set the heater level to maximum mode.
If heat does not flow, it means you have not gotten rid of all the air pockets, which will cause the engine to overheat.

How to completely drain the coolant from the system | VAZ lovers club
This article will discuss the issue of draining coolant from a car engine. The need for such manipulation is due to several reasons.
The coolant must be drained when repairing the engine cooling system, as well as when replacing the thermostat.
Why might it be necessary to drain the liquid?
It is necessary to drain the coolant:
- To replace the thermostat;
- To replace pipes;
- To replace the water pump;
- For stove repair.
When planning to perform any of these manipulations on their own, the driver must be able to drain the coolant and purge the system to avoid the formation of air pockets inside it.
In addition, the coolant itself contains certain substances and additives. Their function is to reduce wear on the vehicle's cooling system.
However, such additives evaporate as the antifreeze is used, which means it must be replaced regularly.
How to drain the coolant?
Before you start draining the coolant, it is necessary to carry out preparatory measures. First of all, you need to prepare the following tools:
- A container with a volume of at least 10 liters. This volume will be enough to accommodate the antifreeze drained from the cooling system;
- Wrench size 13. Experience shows that to drain antifreeze it is better to use the union or end version of this tool;
- Pliers. It is also advisable to have this tool on hand; sometimes it can come in handy.
If the vehicle is equipped with engine protection, the protective parts must be removed. After this, you can see two holes that are designed to drain antifreeze. One of them will be located in the power unit block, and the second in the radiator, in its lower part.
You should start by placing the container in which you plan to place the drained liquid at the bottom, directly under the radiator. If there is reason to believe that liquid will get on the generator, then it must be covered with film.
You can start draining antifreeze only when the engine temperature is not dangerous to human health.
If the engine cooling system is sealed, then antifreeze will not flow until the plug screwed into the expansion tank is removed.
Once there is no more antifreeze in the radiator, the plug must be placed back. After this, you can unscrew the plug from the power unit block, using a pre-prepared socket or socket wrench size 13. In the same way, the coolant located in the “jacket” of the car’s cooling system is drained.
What nuances must be taken into account in order to drain the liquid completely?
In order for all the antifreeze to leave the engine cooling system, the car must be positioned so that its rear half is higher than the front. This arrangement of the vehicle will inevitably force coolant to leave the cooling system.
How to refill antifreeze correctly?
Before you start pouring coolant into the system, you need to make sure that all holes open for draining antifreeze are currently screwed tightly. The process of adding coolant is slightly different on different cars.
The fact is that VAZ cars that are not classified as “classic” (VAZ 2108 and newer models) use a sealed cooling system in which the antifreeze is under pressure.
Based on this, we can understand: to remove fluid from the system of newer cars, it is necessary to unscrew the plug that holds back the pressure in the car’s cooling system.
In addition, you should know that pouring antifreeze into the cooling system of newer cars does not involve purging the system; you just need to turn on the engine, warm it up and let it run for a certain time. But when dealing with classic models, it is strongly recommended to bleed the car’s cooling system. To summarize, we can say: the process of replacing antifreeze does not require special skills or effort.

For efficient and long-term operation of all vehicle systems, the working fluids used must be changed periodically. Requirements for replacing some types of them are not always indicated in the technical documentation for the machine, but this does not mean that the period of their operation is unlimited.
During the operation of any mechanical system, microparticles of metal shavings, peeling of rubber from hoses and other debris are formed. Therefore, it is necessary to replace all types of working fluids at certain intervals. The engine cooling system fluid, antifreeze, is no exception.
In addition to maintaining the temperature regime of the power unit at the required level, this type of liquid is involved in warming up the radiator of the interior heating system, and during circulation in the system, due to the presence of special additives, it also participates in lubricating the parts of the cooling system pump and prevents the appearance of rust in the cooling channels of the cylinder block.
During operation, the liquid gradually loses its properties and needs to be replaced approximately once every three years of operation.
How is antifreeze drained?
Before adding new cooling system fluid, you first need to remove the old one from the system, which will require you to figure out how to drain the antifreeze on your car model.
Helpful advice
Work to drain the coolant must be carried out with the machine installed on a horizontal surface. The correct position of the car will ensure faster removal of old fluid and reduce the amount of its residue in the pipelines and channels of the cooling system.
On most models, a drain plug is provided to drain the working fluid in the cooling system circuit. It is usually located at one of the lowest points of the system, near one of the lower corners of the radiator.
Some car models do not have a drain plug.
In this case, to drain the old fluid, you will need to disconnect one of the lower cooling system pipes connected to the radiator.
You cannot start draining antifreeze on a hot engine. As the liquid heats up, the pressure inside the system rises, and due to the presence of high pressure, the liquid in the system does not boil. At the moment the system is opened to the atmosphere, which happens when the hose is removed or the drain plug is opened, the pressure in the system drops to atmospheric pressure, which can trigger the formation of a jet of steam.
After the engine has cooled, you can begin draining the fluid. We unscrew the cap on the expansion tank of the cooling system, open the drain plug or disconnect the lower pipe and wait until the antifreeze stops flowing out.
But since some of the volumes of the cooling system may be located below the drain hole (for example, the interior heater radiator), it is impossible to remove the liquid located in these areas of the cooling system without additional actions.
The method for draining antifreeze from the specified parts of the cooling system is indicated below.
How to drain antifreeze completely
To figure out how to drain antifreeze from the block without leaving a residue, you need to understand that in any hydraulic system there are areas from which independent flow of liquid is impossible for a number of reasons.
This may be caused by a complex system of cooling channels and their angle of inclination relative to the surface of the earth, as a result of which the antifreeze will not leave on its own without additional pressure. It is also possible that there are sections of the system that are located below the drain point, from which, in the absence of pressure in the system, the liquid will not leave in principle.
Therefore, in order to remove old antifreeze from the cooling system as completely as possible, it is necessary to create pressure that displaces the liquid that has stagnated in the channels.
To completely drain the old antifreeze from the cooling system, you need to screw on the cap of the expansion tank, turn on the interior heating system to maximum and start the engine for no more than two minutes.
Under no circumstances should the engine be allowed to run for long periods of time without liquid in the cooling system.
Due to overheating, the cylinder block will become deformed, the engine will seize, and as a result of the damage received, it will most likely not be subject to repair.
If, after two minutes, fluid continues to leak from the cooling system, it is necessary to turn off the engine, let it cool for at least 15 minutes, and then restart the engine.
After the antifreeze stops flowing out, you need to close the drain plug or fix the pipe on the radiator, and then start filling in new fluid.
After filling the expansion tank to the maximum level, screw on the tank cap and start the engine. During operation of the pump, antifreeze will be distributed throughout the volumes of the cooling system and its level in the expansion tank will decrease.
On a note
The coolant level must be checked again after a few days of using the car, since with a stationary car, the filling of all cooling system pipelines may not be complete, and after they are filled, the liquid level will decrease.
As soon as the antifreeze level drops to the minimum level, it is necessary to stop the engine and add antifreeze solution to the expansion tank until the maximum level is reached, and then start the engine again.
The topping up process must be repeated several times until, after starting the engine, the level of antifreeze in the tank stops decreasing.
Please note that during test runs of the engine the interior heating system is turned on, otherwise the heater radiator will not fill and when it is started, there will subsequently be a significant drop in the coolant level in the system.
As you can see, there is nothing difficult in the process of draining antifreeze. The main thing is not to rush, and this simple procedure will not cause you any trouble.

How to drain antifreeze completely?
Any replacement of antifreeze or antifreeze begins first of all with the fundamental moment of the entire process, namely draining the old used coolant. This question often causes difficulties for car owners. That is why in this article we will pay special attention to this aspect and provide answers to basic questions about the procedure for draining antifreeze.
We recommend reading the full article about replacing antifreeze in cars .
Antifreeze is drained under the following circumstances:
- when repairing or replacing a stove
- when replacing or installing a thermostat
- when replacing the water pump and pipes
- when changing coolant seasonally
- when working out the service life of the coolant
Draining antifreeze in the engine block
Where to start draining antifreeze?
First of all, turn off the engine of your car. Wait about 20 minutes for the engine to cool down completely!
Take a larger container. Ten or fifteen liters should be enough for you. You will need a thirteen socket or socket wrench, and possibly pliers. In rare cases, you cannot do without them.
It is necessary to remove the engine protection, if one is installed. Remove the heating tap. We are looking for two drain holes. The first is located in the engine block. The second look at the bottom of the radiator.
Additionally, cover the generator with a piece of film. We place the prepared containers to the drain hole in the radiator.
Let's move on to the expansion tank. We unscrew the plug slowly and carefully so as not to flood the generator. We wait until the antifreeze liquid drains.
The next step will be draining the antifreeze in the engine block. We are looking for the drain plug. It is usually located under the ignition module. We substitute the container for draining.
Now all that remains is to unscrew the plug in the motor block. We take the key to thirteen and do this manipulation.
In practice, sometimes it turns out that there is simply no plug for draining the liquid. Not intended by the manufacturer or a technological error.
What to do in this case?
It is necessary to disconnect the lower pipe of the engine cooling system, which is routed to the radiator
The coolant drain time will be 10 – 15 minutes.
Ready! The old antefeeze is already in your container. However, most likely some remnants of the old fluid still remain in the system.
How to completely drain antifreeze?
Method 1
The first life hack is connected to the stove, which is installed to the cooling system. Open the oven completely. Then the probability will be very high that all the antifreeze will leak out of the radiator.
Method 2
The second life hack is probably the most tricky and at the same time difficult. You just need to place the front of the car lower than the back. All coolant flows to the main hole.
Sometimes you have to tinker with draining the antifreeze. This is mainly due to the design features of the machine. There are separate areas in the cooling system and engine block where antifreeze sags and can come out by gravity. Therefore, it is necessary to artificially create an angle of inclination to ensure flow out or create additional pressure.
In this difficult operation it is sometimes impossible to do without a jack.
Using a jack, the rear wheels are lifted one by one. Immediately, raise two wheels for 20 minutes, then the right one in turn, after 15 minutes the left.
Sometimes this method is not enough. Therefore, we will create pressure on the system.
We wait until the liquid pours out of the drain hole; do not tighten the drain plug.
Screw the cap on the expansion tank. We turn on the heater in the cabin to the maximum permissible level and turn on the engine. Start the engine for a couple of minutes to prevent overheating of the internal combustion engine and deformation of the cylinder block. In this case, the remaining coolant should flow out. If the antifreeze does not flow out completely after the first start, stop starting the engine for a couple of minutes,
Stopping coolant flow will be a positive signal that everything has come out of the cylinder block.
We complete the draining procedure by tightening the drain plug. Or by installing radiator hoses instead of removing them.
Method 4
Finally, in the most extreme way, the procedure can be completed using a compressor. To do this, just connect it to the cooling system. The compressor will pump air into it and thus squeeze out all the remaining coolant.
Do not forget to tightly close containers with drained antifreeze and dispose of them in specially designated places. Under no circumstances should liquid be poured onto the ground!
We hope that now it is clearer to you and the process of draining the coolant will not cause any difficulties. If we missed any points in the article, write your additions in the comments.
Please note that the article is not a visual aid for all cases in life, the information is based on the experience of most cases, so do not forget to use your manual (car operating manual, for example, Renault, Nissan, VAZ, Volkswagen, Ford, Opel, Fiat , Mazda).

How to properly drain coolant using the example of a VAZ 2114
Novice motorists are forced to contact a car service center and service station for any little thing, since they clearly do not have enough experience to independently service their “iron horse”. However, a lot can be done without the help of specialists, for example, draining the coolant.
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.
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.
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:
- Placing the car on the platform, since ideally it should be in a horizontal position.
- 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.
- Study of the system design and location of antifreeze drain points.
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:
- 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.
- 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.
- 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.
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:
- Opening the expansion tank cap and adding antifreeze to the maximum level.
- 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.
- 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.
- 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.

How to drain coolant: detailed instructions
Cars September 17, 2015
From the article you will learn how to drain coolant from the engine system correctly, without spilling it on the ground or floor in the garage. There may be several reasons for the drain. This includes a complete replacement and repair of the pump and thermostat.
When installing new pipes or radiators, you cannot do without draining the liquid from the system. But you need to adhere to a certain algorithm so that the work is carried out as quickly and efficiently as possible.
First we need to talk about typical malfunctions in the cooling system of any internal combustion engine.
Signs of a cooling system failure
Very often the gasket under the cylinder head is damaged, reducing the volume of coolant in the system. In this case, the liquid can escape, even in small quantities, into the combustion chambers.
This affects both the operation of the engine and the functioning of the cooling system. It is also worth noting that if the thermostat is working properly, the temperature of the main radiator of the cooling system does not change while the engine is warming up.
Therefore, if two or three minutes after starting you touch the lower and upper pipes, and they are hot, then there is a problem with the thermostat. Most likely, its valve is in a position in which the liquid circulates in a large circle.
On the other hand, if even after reaching 90 degrees the temperature of these pipes remains low, we can judge that the jamming occurred in a position in which the liquid circulates in a small circle.
What you need to know before draining liquid
The most important thing is to always carry out work only on a cooled engine! Otherwise, you will get severe burns on your body. Wounds take a very long time to heal, and if you also take into account that antifreeze (antifreeze) is poisonous, then you risk getting a severe allergic reaction.
Getting scalded with hot antifreeze is much worse than with ordinary water, since it is greasy, because in the cooling system it plays a secondary role as a lubricant for the pump bushing or bearing. Can you imagine what it’s like to be scalded with boiling oil (for example, vegetable oil).
The effect is approximately the same. To drain the liquid, you will need a 13mm wrench, a container, and pliers. But the latter are needed in exceptional cases, which will be discussed below. Pay attention to the coolant reservoir; there is a plug on it.
It will be discussed a little below.

How to drain liquid correctly?
So, first prepare the car for repair. While the engine is cooling, you remove the protection from it; it will interfere. The total volume of coolant in the system is about 9 liters.
Having freed up space, you can rest a little by waiting for the antifreeze to cool completely. Place a container under the drain hole on the radiator and estimate the approximate direction of the stream.
For example, on domestic front-wheel drive cars, when the fluid is drained, the stream hits the rear cover of the generator. This is not very good, as you can get a short circuit and burn out the generator.
Therefore, before draining the coolant, it is best to cover it with waterproof material. Place a small gutter so that the stream hits it and all the liquid flows into the container without any residue.
Please note that without unscrewing the plug from the expansion tank it will not be possible to drain all the liquid, since the system is perfectly sealed. After draining the liquid from the radiator, close the hole in it. Using a 13 key, unscrew the second plug. It is located on the engine block.
By analogy, install a small gutter to direct the entire flow of liquid into the container. Without these steps, replacing the VAZ 2114 coolant is impossible. The most important thing when draining liquid is to open the stove tap! It is also advisable to install the car so that its front part is lower than the rear.
This will allow all the liquid to drain to the drain holes.
Which is better: antifreeze or antifreeze?
This question arises very often among motorists. And the answer to it will sound like a question: “Which is better: Coca-Cola or Baikal”? In essence, these are the same thing, only “Baikal”, like antifreeze, is a domestic product.
And abroad, Coca-Cola and antifreeze are more popular. Antifreeze is antifreeze. Any liquid that does not freeze in the cold is antifreeze. But there are differences.
And before draining the coolant to replace it, it’s worth learning about the nuances.
Antifreeze was developed by domestic scientists about half a century ago, it has become widespread, and is not inferior to its foreign analogue (which everyone calls “antifreeze”) in its characteristics.
Antifreeze is distinguished by its blue color and a completely different composition. Unfortunately, foreign brands of this liquid contain many more additives that improve its characteristics and extend its service life.
And what to choose - antifreeze or antifreeze (the price of these liquids is almost the same), it’s up to you to decide.
Replacing the thermostat
It is only necessary to replace the failed thermostat. It is located directly on the internal combustion engine. Several pipes are connected to it.
As a rule, one goes to the expansion tank, the second to the radiator, the third to the water pump, and the fourth is connected to the cooling jacket of the cylinder block.
Please note that all work must be carried out only after the liquid in the cooling system has completely cooled. And before starting repairs, it is necessary to completely drain the antifreeze from the system.
Unscrew the clamps that are located on the pipes, and then remove them. Please note that in this case the antifreeze must be completely drained. Its price, by the way, is about 700 rubles for a 10-liter canister.
Conclusion
If you notice that the temperature has reached a critical level, you must immediately identify all the causes of the malfunction, as well as quickly take measures to eliminate them immediately.
On the other hand, an excessively low engine temperature also leads to increased wear of all elements of the internal combustion engine.
The air-fuel mixture practically does not evaporate; it removes the oil film from all cylinder walls.
Regardless of the symptom of the breakdown, hypothermia or excessive heating, there is a malfunction in the system that should be corrected as soon as possible.
Now you know how to drain coolant from an internal combustion engine. Good luck!
