How much antifreeze is in the Niva cooling system

The Niva SUV, in all modifications, is very popular in Russian spaces. This is due to good maintainability, low price and excellent maneuverability. To ensure reliable operation, you should undergo all maintenance on time, in particular, replace the coolant.

The liquid system with forced circulation of the VAZ 21214 car is designed for effective heat removal. It fully copes with its task, you just need to keep it in good condition.

Replacing antifreeze VAZ 21214

Replacing the coolant is a regulated maintenance procedure, which is prescribed in the operating instructions. There is nothing complicated about it if you clearly and carefully follow the described action plan.

Suitable for Niva cars:

Coolant drain

Before starting the draining procedure, you should prepare tools, containers for used antifreeze, as well as new liquids for subsequent refilling. If protection is installed under the engine, it can also be removed for convenience.

Next, we perform the procedure for draining the liquid from the VAZ 21214 (Niva):

turn the temperature regulator in the cabin to the maximum position to the right (Fig. 1);

Flushing the cooling system

If there are deposits in the drained liquid or there is a transition from antifreeze to antifreeze, the system should be flushed. To do this you need to do the following:

Flush the system with plain water through the expansion tank of the VAZ 21214. The plugs must be open;
tighten the drain plug and bolt;
fill the system with a flushing agent (you can use Liqui Moly Kuhlerreiniger or Lavr cooling system flush) with distilled water (6-7 liters);
start the engine. Warm up to 90 degrees;
leave it idling for 5-10 minutes, depending on the contamination of the system;
muffle it. Allow the engine to cool to approximately 60 degrees;
drain the flush using the same steps as removing the old fluid;
tighten both plugs;
fill with distilled water to rinse the cooling system;
start the car and warm up to 90 degrees;
turn off and let cool to 60 degrees, drain;
repeat steps 8, 9, 10 and 11 if necessary.

Filling antifreeze into Niva 21214, 21213 without air locks

To fill new fluid into the cooling system, you can use the instructions described in the book on car repair and operation. But when doing this, motorists very often end up with air jams.

So, let's start filling it correctly:

before filling, unscrew the hoses supplying antifreeze to the throttle valve heating unit and lift them slightly up (Fig. 1);

The filling of the liquid is completed, all that remains is to wipe off the spilled antifreeze and wait for the engine to cool. With the car now cooled down, check the level in the expansion tank again and top up if necessary.

Fill

To fill in new antifreeze, you don’t have to do anything complicated.
You just need a special watering can. Many containers in which antifreeze is sold are not particularly convenient for pouring directly from them. Use a funnel to avoid spilling coolant. It is extremely important to know exactly how much antifreeze is in the cooling system. The coolant for the VAZ 2109 requires 7.8 liters. Therefore, antifreeze should be purchased in 8-liter containers.

Take a watering can and insert it into the neck of the expansion tank. This way you won’t spill precious grams of antifreeze.
Check that all drain plugs are securely tightened. Otherwise, the coolant will simply spill out onto the floor and you will have to buy new coolant.
Start gradually pouring in new antifreeze.
Stop periodically for 1-2 minutes so that the liquid has time to distribute throughout the system.
After filling the system, add coolant to the middle of the expansion tank level.
Next, the most important thing is to get rid of the air that has entered the cooling system.
Air accumulates in the upper pipe. To remove it, you just need to squeeze the upper pipe several times. Squeeze until you feel liquid appear inside.
Bleed the cooling system. To do this, use a screwdriver or a size 8 wrench to unscrew the clamp that holds the return hose to the CO expansion tank (return).
Now close the fitting with your finger, onto which the return line is put, so that air cannot escape from there.
Next you need to blow into the expansion tank. Just imagine that you are trying to inflate the tank like a balloon.
This will create pressure and coolant will begin to flow from the expansion tank into the CO, and excess air will escape through the return.
As soon as antifreeze begins to flow out of the return line, the procedure can be stopped.
Replace the return line and tighten the clamp.
Reconnect the negative terminal of the battery, close the cap of the expansion tank and check the quality of the work done.

is not recommended to start active operation of the car without checking.

Replacement frequency, how much and what kind of fluid is needed

According to the manufacturer's recommendation, it is necessary to replace antifreeze or antifreeze on VAZ-21214 cars every 3 years or after a mileage of 60 thousand kilometers. If the car is used in more severe conditions, then it is advisable to replace it more often - every 30-40 thousand kilometers.

In addition to the recommended coolant change intervals, there are other reasons why it is necessary to change the fluid in a car's cooling system:

loss of coolant properties. You can check the quality of the antifreeze used using a test strip, which is sold in the same places where the liquid itself is sold. Place the strip in the expansion tank, then pull it out. The strip comes with a color scale, according to which you can understand how much longer the car can be used before replacing the coolant;
change in color of the coolant to tan or red. This means that rust has appeared in it;
the appearance of sediments, flakes and dense formations in the liquid.

The coolant for the VAZ 21214 Niva injector should have a freezing point no higher than -40 degrees. Typically, the manufacturer fills in TOSOL TS-40 (manufacturer in Dzerzhinsk). When replacing antifreeze, it can be replaced with antifreeze with G12 approval; it is safer for the entire cooling system. You can also use original Lada G12 antifreeze, which is suitable for all cars of this manufacturer.

Replacing the heater valve VAZ 21214 Niva without draining antifreeze

Niva cars sometimes have problems associated with the failure of some parts of the cooling system, such as a thermostat or pump. If they break down, they are replaced as an assembly, fortunately they are not expensive. Also a common problem are leaking hoses or a cracked expansion tank, which also needs to be replaced.

But there is another problem with the VAZ 21214, a leaking heater valve. Because of this, there may be a smell of antifreeze in the cabin, wet floor mats on the front passenger side, or the heater may not work.

There are several ways to replace a faulty faucet:

complete draining of antifreeze from the system;
clamp the stove pipes with special clamps;
Place your Niva on a slope, with the hood down.

But there is another option that is more clear and simple. To do this, you need to disconnect the pipes going to the stove under the hood, point them upward and fix them in this position. The next step is to remove the stove itself:

unscrew the console;
disconnect the latches securing the stove;
there is no need to disconnect the buttons;
move the radiator assembly, along with the tap and pipes, towards the driver;
we take out the entire structure through the space between the steering wheel and pedals;
That's it, you can change the tap itself.

The procedure for draining antifreeze on a Niva VAZ 2121

The first step is to cool the engine if you have recently turned it off, that is, wait until it cools down to the outside temperature.
Then unscrew the radiator filler neck.

And disconnect the hose that goes to the engine block, thereby draining the antifreeze from the block:

And we substitute some kind of container, you can make it from an old 10-liter plastic canister by cutting off its upper part.
Next, you need to drain the antifreeze from the Niva’s radiator. To do this, use a 13mm head to unscrew the plug, which is located at the very bottom of the radiator on the left side. You can see everything clearly in the photo below:

And again we substitute a container to drain the old coolant. After there is no antifreeze left in the cooling system, you can begin to pour fresh coolant through the expansion tank in a thin stream to avoid the formation of an air lock. We pour until the required level is reached - approximately in the middle of the expansion tank. And then we do the same procedure with the radiator until its upper tubes are hidden. Don't forget to first attach the hose to the outlet of the engine block.
Antifreeze or other coolant should be poured through the expansion tank until the level in it reaches the maximum level.

Chevrolet Niva is a well-known car, which is deservedly considered the most economical and functional at the same time. Replacing antifreeze on a Chevrolet Niva is not much different from other cars, but this process has its own nuances. It’s worth noting right away that, unlike other cars, this one needs to change the coolant, namely antifreeze, once every two years, or once every 60 thousand kilometers

In order to know which antifreeze to use, which is better, and how to replace what, there are special instructions for the car that will tell the driver which products are ideal for this car. Self-repair of a car is what brings a person and a car together best of all, and a process such as replacing a cooler cannot even be called a repair.

Frequency of replacing the coolant of a VAZ 21214 car

First, it’s worth making a small digression. It is believed that the Niva should be filled with antifreeze, a domestically produced coolant. But drivers should remember: antifreeze is the name of the coolant that was produced in the USSR. And at the moment it is no longer produced. But many domestic companies continue to call their products antifreeze. Despite the fact that, in essence, this is standard antifreeze.

But what about the frequency of replacement ? For original AvtoVAZ fluid, it is recommended to replace it every 60 thousand km. If the mileage is low - 3 years after filling in new coolant. If you use antifreeze from other manufacturers, you must check their recommendations. On average, for coolant brands G12 or G12+ it should be replaced every 200-250 thousand km or once every 5-7 years.

But it’s also worth talking about the recommendations of experienced car owners . Here's what they advise:

Periodically check the condition of the antifreeze in the system. There are a number of factors that reduce the service life of a fluid. Here it is necessary to mention: temperature changes, dust and dirt, uneven speed limits. In case of intensive use of the car, a check should be carried out every 30-40 thousand km.
When buying a used car, the antifreeze is changed immediately. Some owners fill the coolant system with low quality or plain water. Therefore, it is advisable to change the fluid immediately. It is also worth checking the condition of the radiator, expansion tank and pipes for leaks and damage.
When switching to another type of antifreeze, a complete flushing of the system must be done. It is necessary to remove dirt and residual additives from the old coolant.

When replacing the coolant in a VAZ 21214 “injector”, a volume of antifreeze equal to 10.7 liters. This is the standard amount of coolant for any Niva car model. It’s worth noting here that the principles of filling and volume are the same for all Nivas. This also applies, for example, to replacing the coolant in Niva 21213, or Lada 4×4 Urban. By the way, Lada 4×4 is the new name of the Niva series models. It's worth keeping this in mind when looking for replacement parts.

Now it’s worth understanding the signs of replacing the coolant in Niva. You need to pay attention to the following points:

The engine overheats quickly. The thermometer needle is constantly in the red zone. The fan runs almost continuously.
The pressure in the system is higher than normal. This is due to the appearance of plugs in the cooling circuit.
The color and consistency of the liquid have changed. The antifreeze has lost its transparency and dirt has appeared in it. In the worst case, the coolant has an unpleasant odor.

If the described problems occur, the antifreeze must be changed.

How much antifreeze is included in the eye?

This video will show how easy it is to replace antifreeze, Oka will not give any difficulties with this. It’s easy to change antifreeze or other coolant on the Oka with your own hands.

When to change and how much coolant to fill

The Oka repair manual indicates that the frequency of replacing coolant is 60,000 km or every two years.

The manual also states that the filling volume of the cooling system is 4.8 liters.

How to change Oka antifreeze

First, you should open the heater tap by moving the lever in the cabin to the right all the way. Then place a container under the radiator where the coolant will drain. After this, you need to unscrew the drain plug on the radiator and remove the cap on the expansion tank . You should also drain the fluid from the cylinder block by unscrewing the drain bolt.

After draining the liquid and tightening the drain plugs on the radiator and cylinder block, you need to install a funnel and pour new antifreeze or antifreeze into the expansion tank to the top edge. Then start the engine and let it warm up to operating temperature so that the fan turns on. Now all that remains is to check the fluid level in the tank and top up if necessary.

This video with instructions will help you see how to replace the coolant on an Oka car.

What to do if liquid leaks? What kind of breakdowns happen?

Often problems in the cooling system are caused by breakdowns and leaks. And the condition of the antifreeze does not play any role here. Here is a list of possible malfunctions and how to fix them:

Thermostat failure. This part is responsible for the connection between the external and internal circuits of the cooling system. In normal condition, it remains cold at operating temperatures below 80-85 degrees. If the liquid heats up more, the thermostat becomes hot. If there is a malfunction, the thermostat no longer heats up, or is constantly hot. And then it has to be changed. It is worth remembering that this part cannot be repaired, only replaced.
Pump breakdowns. Possible problems: broken impeller blades, cracks in the housing, failure of seals. In case of leaks, it is worth checking whether the problem is in the pump or in the hoses.
Problems with the cylinder block. If cracks appear or there is a manufacturing defect, you will have to turn to professionals. But sometimes problems arise due to a rotten block cover gasket. This is usually due to the use of ordinary water in the cooling system. Diagnosis is simple: dense, white or bluish smoke constantly comes out of the exhaust pipe. Here the cylinder block gasket is replaced.
Development of the service life of system hoses. The solution is simple - replacing the hoses. It is done by hand. Tools: pliers and a screwdriver for removing clamps. Old hoses are removed and thrown away, new ones are installed in their place.
Problems with the expansion tank. Cracks appear on it, and the container has to be replaced. The procedure is simple: the screws on the tank fastenings are unscrewed, the old container is removed, and a new one is installed.
Problem with radiator fans. There are two of them. One or both can fail at once. Repairs can only be made by an experienced electrician.
Radiator leaks. Corrected by repair or replacement of the part. But you won’t be able to fix this on your own; you need the help of a professional.

Niva Chevrolet: cooling system

Engine operation at normal temperature conditions is ensured by the functioning of the components included in its composition . This is a closed-type pipeline with forced ventilation.

List of elements providing heat exchange:

The pump operates under the influence of centrifugal force . As the blades rotate, coolant is pumped, creating a pressure difference, so the antifreeze moves along the line.

For the efficient functioning of the heat exchanger, which includes a radiator, a thermostat is provided to open and close the movement of coolant in a circle. The latter is necessary to maintain balance in the system and has factory settings - it opens at a temperature range from 75 to 80°C.

The radiator contains two tanks connected horizontally by aluminum channels:

one receives coolant;
from the other - coolant comes out.

Heat exchange is provided over the radiator area.

When heated, a liquid tends to expand. To avoid the creation of excess pressure, an expansion tank is designed to receive it . The latter is equipped with a cover with a bypass valve to increase the pressure in the system. By switching to a closed type, it was possible to increase the boiling point and eliminate losses due to leakage from the tank.

Airflow of the heat exchanger is provided by fans operating in two modes:

How to properly replace coolant?

You need to start replacing the coolant on a VAZ 21214 by choosing a suitable refrigerant . You can choose the original coolant, or choose one of the available analogues. The original antifreeze has been produced since 2014. Name of liquid: Antifreeze LADA G12. Designed for use at temperatures down to -40 degrees Celsius. Product number: 88888-2000010-82.

When choosing a liquid, you need to pay attention to its labeling. For Niva (including VAZ 21214) you need a coolant with an operating temperature no higher than -40 degrees. The following liquids are suitable:

Antifreeze of domestic production. You need to take a high-quality coolant. The marking “Antifreeze -40” means a freezing temperature of -40 degrees. For regions in the Arctic Circle, antifreeze labeled “Antifreeze -65” is suitable. An example of a suitable liquid: Felix antifreeze.
Standard antifreeze. Both domestic and foreign coolants are suitable. Here again the minimum operating temperature is checked. It is equal to -40 degrees Celsius. Example: products from G-Energy or SINTEC. Felix Carbox antifreeze will also work.

It’s also worth considering that the original LADA antifreeze is sold in an already diluted form. But when purchasing concentrate from other companies, it should be diluted. The exact proportions are written on the coolant packaging.

Tools and materials for work

Then you need to figure out the tools and materials.

The list of tools for replacing coolant in a VAZ 21214 looks like this:

Container for draining used antifreeze. Volume - 12 liters.
Thick and durable coolant drain hose.
Wrenches for 13 and 15. It is recommended to have box, open-end and ratchet wrenches of the appropriate size in the kit.
Funnel for filling the radiator and expansion tank.
Round nose pliers for removing the receiver hose.
Cooling system flushing products.
Antifreeze to replace. The Niva’s cooling system holds 10.7 liters. Therefore, 11 liters are purchased, with a small reserve in case of leaks.
WD-40 for cleaning screws.

Vehicle preparation and safety precautions during operation

The next step is to prepare the car for replacing the coolant. It goes like this:

The Niva is driven onto an overpass or placed above an inspection hole.
The car is firmly secured: it is put into speed and the hand brake is applied. It is recommended to install wheel stoppers.
The motor is allowed to cool. Working with hot antifreeze is inconvenient and hazardous to health.

It is also worth remembering safety precautions . Here are a number of simple but important recommendations:

Antifreeze should not come into contact with eyes or respiratory tract. This liquid is toxic and is a strong poison.
Work should be done in a ventilated area. Coolant fumes are not beneficial to health.
You should wear comfortable, loose clothing. The work uniform does not restrict movement and does not interfere with the process of replacing antifreeze.
Coolant must not get into the fuel. This will have a very negative effect on the operation of the motor.

Now you can proceed to the actual replacement procedure.

Power unit

The engine installed on the modern model of the Niva 21213 (214) car was inherited from its Soviet progenitor - the VAZ 2121, and in terms of fluid volumes they are almost identical:

Liquid cooling system. Filled with antifreeze in an amount of 10.7 liters with a freezing point not higher than -40 ° C. The capacity of the interior heating radiator is also included in this volume.
Crankcase. Motor oils are poured here, the brand of which depends on the operating conditions. Capacity: 3.75 liters, including oil filter filling.

The viscosity of the oil poured into the Niva engine must correspond to the outdoor temperature at which the car is operated. Possible modes and suitable oil brands are shown in the table:

When flushing the power unit during the process of replacing liquid lubricant, the same amount of flushing oil (3.75 l) is used, taking into account the size of the filter. Replacement is carried out after 8-12 thousand kilometers, depending on the quality of the oil. Flushing is usually performed after 3 engine lubricant changes. During operation, it is important to monitor the oil level in the engine crankcase using a special dipstick. If the level drops below the Min mark, it is urgent to add lubricant to the engine of the same viscosity as was previously filled.

Antifreeze needs to be updated at least once every 3 years or according to the degree of wear of the fluid. It is not recommended to dilute antifreeze with distilled water, either in winter or summer. In winter, the diluted liquid may freeze, and during the summer heat it may boil ahead of time, which will lead to overheating of the engine.

Stage one

You should start by draining the used antifreeze . It is recommended to remove the crankcase protection and move it to the side. It is fastened with standard 13 bolts. The protection is neatly removed to the side. After this, the antifreeze is drained. The process looks like this:

When the engine has cooled down, the heater levers are pushed back all the way.
Use pliers to disconnect the receiver heating hose. This is done to bleed excess air from the system. In older models with a carburetor fuel supply system, the carburetor heating hose is disconnected.
A container for used antifreeze is installed under the drain hole on the radiator.
The drain valve on the radiator opens. If necessary, it is pre-treated with WD-40. To speed up the draining process, remove the radiator filler cap. All the liquid is drained, to the last drop.
Next, the antifreeze is drained from the internal cooling circuit located in the engine. Use a 13 key to unscrew the plug on the left side of the cylinder block. It is located near the spark plug of the fourth cylinder. A hose is placed under the drain hole and the used coolant is drained through it. The plug is then screwed into place.
The expansion tank is carefully unscrewed. Then it rises above the level of the radiator - 30-40 cm is enough. The hose going to the radiator is disconnected and sent to the drain container. The tank is washed if necessary, then installed in its original place. The remaining fluid is drained from the radiator again.

In total, there are about 10 liters of antifreeze in the system. Therefore, it is worth paying attention to the volume of drained liquid . Here we must remember: the liquid from the cooling circuit evaporates very reluctantly. Therefore, even in hot weather, the volume of antifreeze in the system decreases very slightly. And if the used antifreeze is less than normal, then it is advisable to check the cooling circuit for leaks or damage.

How much antifreeze is included in the field?

The engine cooling system, together with the interior heating system, holds 10.7 liters of coolant (coolant).
If much less enters the system, it means that an “air lock” has formed . That is, before pouring antifreeze, you need to let the air escape.

This can be done by pouring a little antifreeze by starting the engine (without accelerating) and letting the engine run a little at low speeds. Then turn off the engine and add antifreeze.

Coolant replacement on a VAZ 2121 and Niva 2131 is carried out according to the technical inspection card or following the instructions of the fluid manufacturer. The liquid is also drained when performing other various works, when repairs to the cooling, heating, etc. system are required. To carry out repair work, prepare a standard set of tools, an empty drain container, and new coolant. If you have everything you need, do the following:

Drive the car onto a viewing hole or overpass.
Open the heater tap inside the car on the instrument panel.

Place an empty container under the radiator drain plug and unscrew it to drain the liquid.
To drain the liquid from the engine, use a thirteen-size spanner to unscrew the drain plug located at the bottom of the cylinder block and drain the liquid from the cooling jackets.
To drain the liquid from the expansion tank, loosen the clamp of the outlet hose on the radiator pipe and remove it, draining the antifreeze from the tank.
After the system is drained, fill in a new one. It is necessary to fill through the radiator neck to its upper edge, in the process squeezing the cooling pipes so that air can better escape from the system. Close the radiator cap.
Add antifreeze to the expansion tank, bringing its level to the corresponding mark on the body.
Start the engine and allow it to warm up while monitoring the temperature on the instrument panel.
We stop the engine, let it cool a little and check the level, if necessary add fluid.

At this point, the repair work to replace the coolant on the VAZ 2121 and Niva 2131 has been completed.

The coolant on the Niva 2121 and 2131 is replaced when water gets into the system or when the liquid begins to darken, which indicates a loss of its basic properties. Prepare a standard set of tools, and then perform the following sequence of actions:

The car must be driven onto a viewing hole, overpass or lifts.
Remove the engine compartment protection.
Open the cap of the expansion tank to allow the fluid to drain better.
We place an empty container under the radiator drain plug and open it. After the liquid has drained, screw in the plug.
Next, unscrew the drain plug of the engine block and drain the liquid in the same way. Then we wrap it.
If necessary, flush the system by pouring water with special additives into it, which can be purchased at an auto store. Also, flushing compositions can be poured in immediately before the old liquid is drained, it all depends on the method of application of the composition used.
Fill new fluid through the radiator filler neck to the bottom edge of the filler neck.
Then add liquid to the expansion tank, bringing it to the middle mark between maximum and minimum.
We tighten the radiator and expansion tank caps and start the engine, letting it run for a while. Check the level and add more if necessary.

Stage two

The next step is flushing the system . It is required when the circuit is heavily contaminated or when switching to another type of antifreeze. For example, when the original coolant for a VAZ 21214 is replaced with compounds from other manufacturers. They differ in the set of additives and composition, and they cannot be mixed.

There are three washing options. The method should be chosen based on the operating conditions of the vehicle. Antifreeze residues and dirt are washed out using the following means:

Distilled water.
Household chemical solutions.
Special cleaning products.

What to fill in Chevrolet Niva: antifreeze or antifreeze?

alt=»thumbnail» />
It is necessary to fill the Chevrolet Niva with antifreeze, strictly observing the established frequency. It is assigned by the manufacturer and amounts to one fill per 40 thousand kilometers. In exceptional cases, if the driver uses the vehicle little, antifreeze can be added once every couple of years.

It should be borne in mind that the volume of antifreeze should be regularly checked and urgently changed if a brownish tint or dark color of the liquid is detected. In addition, replacement of technical fluid is necessary if it does not meet the established density values or the engine requires major overhaul.

What antifreeze should I put in a Chevrolet Niva?

Many car enthusiasts are interested in the question: what antifreeze is best to fill in a Chevrolet Niva? When choosing the right composition, the car enthusiast will need to rely on the advice provided by the manufacturer and on his own experience in operating and maintaining these cars.

Stage three

The last step is pouring new antifreeze into the cooling system. And before filling it is worth checking whether the coolant needs to be diluted. comes already diluted. But a number of other liquids require that they be diluted with water. The proportions are indicated on the packaging.

The filling process itself looks like this:

The radiator is filled with antifreeze through the filler hole. It needs to be filled to the bottom level of the neck. Then the plug is screwed on.
The remaining antifreeze is poured into the expansion tank. The container must be filled to a level located 3-4 cm above the MIN mark.
The engine warms up to operating temperature. There is a simple way to check: by the temperature of the lower radiator pipe. When it starts to heat up sharply, it means the engine has warmed up to operating temperature. And antifreeze began to circulate through the cooling system.
After 10-15 minutes of warming up, the engine is turned off. Now the driver must wait for the unit to cool down. Then the antifreeze level is checked again. During normal system operation, this level will drop significantly. The coolant is topped up to the previous level.

Now all that remains is to install the crankcase protection in place and tighten all the plugs in the cooling system tightly. It is worth driving the next day in break-in mode, checking the condition of the car after replacement. If the Niva’s antifreeze is suitable and no problems appear, then the replacement was successful.

Transmission

The Niva 4x4 transmission system has the following filling volumes:

transfer case - 0.79 l;
gearbox - 1.6 l;
rear axle - gearbox - 1.3 l;
front axle - crankcase - 1.15 l;
steering column - crankcase - 0.18-0.2 l.

Replacement of antifreeze on Niva 21214 cars, according to the manufacturer’s recommendation, should be done every 3 years, or after 60,000 mileage. When operating in difficult conditions, it is advisable to carry out work more often - every 30-40 thousand kilometers.

What antifreeze and how much should I fill in Niva-21214?

When choosing coolant for Niva 21214, you should rely on the manufacturer’s recommendations. Based on application practice, the following types of antifreeze can be used:

For cars produced in 2009, red coolant G12+ is suitable. The optimal options are Zerex G, VAG, Frostschutzmittel A, and FEBI.
For Niva 21214 cars produced after 2010, it is worth using red G12++ class antifreeze. The most popular manufacturers here are Castrol Radicool Si, MOTUL, Freecor QR, Freecor QR, FEBI and others.

Other coolants also performed well - Sintek, Cool Stream (Premium and Standard), as well as TC Felix Antifreeze.

Antifreeze should be replaced not only during the periods indicated above, but also if a reddish tint appears. This indicates a deterioration in the composition of the coolant or the presence of a counterfeit in the cooling system.

The optimal volume of antifreeze required to refill the system is 10.7 liters.

Replacement process

Work is carried out only on a cooled engine and on a level area (pit, overpass). If a horizontal section cannot be found, a slight lifting of the front of the car is allowed.

Before draining the antifreeze, remove the negative terminal from the battery, and also remove the protection from the motor (if installed). Afterwards, prepare the necessary tools. To replace antifreeze on a Niva 21214 car, you will need “fifteen” keys, a “thirteen” socket with a knob and an extension, as well as a ratchet handle (it will be more convenient with it). Also buy new antifreeze to fill the system, find a container larger than 11 liters, as well as a dry rag.

Head into the salon and open the heater tap.
In the engine compartment, find the expansion tank and unscrew the plug from it.
Unscrew the radiator cap. At the initial stage, this may not be done. If you leave the cap in place, the coolant will come out with less activity, which eliminates splashing.
Place a container with a volume of 11 liters or more under the approximate location for draining. At the same stage, prepare a tube having an internal diameter of 1.6 cm.

Antifreeze drain

Let's look at how to drain antifreeze from a radiator. To do this, remove the cover, which is located on the left, at the bottom of the device, connect the prepared tube to it and wait until the coolant leaves the system. The presence of a tube is necessary to avoid splashing of dangerous liquid.

Proceed to the next step - drain the old antifreeze from the cylinder block (hereinafter - BC) of the Niva-21214 engine. To do this, do the following:

take a key set to “thirteen” (preferably with a socket and an extension), then unscrew the plug installed on the lower left side of the engine BC;
drain the coolant from the system using the same hose as for the radiator.

Drain the antifreeze from the expansion tank. For this:

remove its fastening, open the plug and raise the container above the level of the radiator filler outlet; these actions are enough for the remaining antifreeze to come out of the tank;
Now tighten the drain plugs, place and secure the expansion tank in its original place.

When replacing antifreeze, please note that the connection for the BC plug uses a conical thread. Its peculiarity is that there is no need for compaction. The plug on the Niva-21214 cylinder block is pulled with a force of 25-30 N*m using a torque wrench.

Filling with new antifreeze

Go through the final stage of replacing antifreeze - fill in the prepared coolant. For this:

Pour antifreeze into the radiator hole. Make sure that the upper coolant level reaches the top edge of the filler hole.
Pour coolant into the expansion tank. The level should be 30 mm above the MIN sign.
Start the engine and let it warm up. The cap on the radiator must be closed. Pay attention to the hose leading to the radiator from the engine. It will be cold for a while, but after a few minutes it will warm up. This confirms the fact that the liquid went in a large circle.
Wait until the fan starts and turn off the engine.

Wait for the coolant to cool, check the level again and top up (if required). At this point, the replacement of antifreeze is completed. If necessary, expel air pockets from the system, for which, let the engine run with the radiator cap removed (the front of the car should be higher than the rear).

Now you know how to drain the antifreeze in a Niva 21214 car, and then fill the system with new coolant. This information is enough to do all the work yourself and not contact specialists.

The cooling system is liquid, closed type, with forced circulation. The tightness of the system is ensured by valves in the expansion tank plug. The inlet valve is normally open (the gap between it and the rubber gasket is 0.5–1.1 mm) - in this case, the system communicates with the expansion tank.

When the engine heats up, the liquid expands and is forced into the tank; when it cools, it returns back. The inlet valve closes when there is a sharp increase in pressure in the system (boiling liquid), while the outlet valve is also closed. It opens when the pressure in the system reaches approximately 0.5 kgf/cm2, which increases the boiling point of the liquid and reduces its losses.

The thermal operating conditions of the engine are maintained by a thermostat and a radiator fan. On a carburetor engine, the fan is mechanically driven and mounted on the coolant pump pulley. On an engine equipped with an injection system, two electric fans are installed in front of the radiator and are activated by command from the electronic engine control unit. The coolant pump is a vane, centrifugal type, driven from the crankshaft pulley by a V-belt. The pump housing is aluminum. The roller rotates in a double-row bearing with a lifetime supply of lubricant. The outer ring of the bearing is locked with a screw. A pulley hub is pressed onto the front end of the roller, and a plastic impeller is pressed onto the rear end. For the correct position of the pump pulley groove, the distance from the mating surface of the pump cover to the outer end of the hub must be 84.4 ± 0.1 mm.

When installing the cover with the gasket, check the gap of 0.9–1.3 mm between the impeller blades and the pump housing. To do this, you can use plasticine rollers: they are placed on equidistant impeller blades, a cover is installed, the nuts securing it are tightened, then the cover is removed and the remaining thickness of the plasticine is measured - it is equal to the gap. Axial and radial play in the pump bearing that can be felt by hand is not allowed. If the bearing or self-pressing seal of the pump fails, it is recommended to replace the pump cover complete with the roller and impeller. The redistribution of liquid flows is controlled by a thermostat with a solid heat-sensitive element. On a cold engine, the thermostat valve closes the pipe leading to the radiator, and the liquid circulates only in a small circle (through the thermostat bypass pipe), bypassing the radiator. The small circle includes the heater radiator, intake manifold, carburetor heating unit (on engine 21213) or throttle assembly (on engine 21214). At a temperature of 78–85°C, the valve begins to move, opening the main pipe; in this case, part of the liquid circulates in a large circle through the radiator. At a temperature of about 90°C, the main valve opens completely, and the bypass valve closes, and all the liquid circulates through the engine radiator. The main valve stroke must be at least 6.0 mm. You can evaluate the serviceability of the thermostat by heating the lower radiator pipe: it should be cold until the liquid temperature (according to the indicator) reaches 80–85°C, and hot when it rises to 85–90°C. The thermostat is beyond repair. In case of malfunction, loss of tightness, or deformation of the pipes, it is replaced. The radiator consists of two vertical plastic tanks (the left one has a baffle) and two horizontal rows of round aluminum tubes with pressed-on cooling plates. To increase cooling efficiency, the plates are stamped with a notch. The tubes are connected to the tanks through a rubber gasket. The liquid is supplied through the upper pipe and discharged through the lower. There is a coolant drain plug at the bottom of the left reservoir. For better radiator airflow, casings are designed to direct air flow from the fan(s). On the 21213 engine, the main fan shroud consists of two halves (lower and upper), the lower half has a rubber seal on the radiator side. An additional guide casing is installed in front of the radiator. On the 21214 engine, electric fans rotate in a casing in front of the radiator. The expansion tank is made of translucent polyethylene, which allows you to visually monitor the fluid level (3–5 cm above the “MIN” mark on a cold engine). To monitor the coolant temperature, a sensor is screwed into the engine cylinder head and is connected to a temperature gauge on the dashboard. An additional temperature sensor is installed in the exhaust pipe of the 21214 engine, which provides information to the electronic engine control unit.

The cooling system is filled with 10.7 liters of coolant with a freezing point no higher than -40˚.

Volumes of filling tanks VAZ 21213 Niva

To refuel and service a domestic VAZ SUV, you need to know the filling capacities of the VAZ 21213 Niva and its modifications, the VAZ 21214. Some numbers need to be known by heart, for example, the capacity of the tank and engine crankcase. The rest should be written down in a notepad, which is stored in the glove compartment of the cabin. And it doesn’t matter that you are not going to do the maintenance of the car yourself, the specialists at the service station may also not know the refueling volumes of your car.

Sequence of work performed:

1. Drive the car onto a platform that allows the right front wheel to lift, or into a pit. 2. Be sure to cool the internal combustion engine to ambient temperature. Attention, opening the lid prematurely may cause hot antifreeze to splash out. 3. Open the heater lever from the passenger compartment;

4. It is recommended to first disconnect the carburetor or receiver heating hose to bleed air;

5. Unscrew the radiator filler cap; 6. Substituting the container, use key 13 to release the fitting in the lower part of the block (in the area of the 4th cylinder spark plug) belonging to the engine cooling jacket;

7. Open the tap in the lower left corner of the radiator;

8. Unfasten the expansion tank, then, lifting it, drain the coolant through the radiator;

9. Return the unscrewed plugs to their place, except for the throttle valve heating hose. 10. Proceed to fill the system with coolant through the radiator to the maximum mark; 11. Press the hoses to prevent air locks ; 12. Continue filling through the tank to the set mark, repeat pressing the hoses or rock the car; 13. Then screw in the radiator filler plug for 10-15 minutes at low speed until warm air flows through the heater sockets; 14. Add antifreeze through the expansion tank to the level; 15. Close the tank cap and connect the heating hose.

Replacing antifreeze with modern antifreeze in VAZ 21212 and 21214 without preparation is not permissible due to the different set of additives and functional qualities. In this case, before changing the coolant, flush the system with clean running water.

What coolant is recommended for Chevrolet Niva

The best option when choosing a coolant would be products containing:

propylene glycol or ethylene glycol (aggressive substance);
distilled water;
additives (silicate, carbosilicate or hybrid).

Products with carbosilite additives have excellent heat transfer, increased cooling temperatures and a long service life ; they also prevent the formation of fatty deposits. Silicate additives help reduce temperature and cause rust.

Important! A high-quality coolant must have increased thermal conductivity and a high boiling point. During operation, foam and scale should not form, and in the cold season the liquid should not freeze.

Antifreeze G12 is ideal for a Niva Chevrolet car . The coolant is replaced every 2 years or after 60 thousand km. If the color of the fluid has changed, this is another reason to replace the coolant. When acquiring a reddish tone, you should pay attention that the chemical properties of the composition have changed.

To accurately determine which antifreeze to fill, you need to know what product was filled at the factory. It all depends on the model and year of manufacture of the car :

If the cars were produced in 2001, then choosing the G12 class will be a good option.
If the model was released between 2003 and 2010, then G12 +.
For more modern models produced after 2010, it is recommended to purchase G12++ antifreeze.

Instead of antifreeze, you can use TS-40 . This is Antifreeze from a domestic manufacturer.

Other liquids and fuels and lubricants

Every car enthusiast should know by heart the maximum fuel capacity of his car. The fuel tank of the VAZ 21213 has a capacity of 42 liters, including reserve. The reserve refers to the amount of fuel remaining in the tank after the yellow warning light on the instrument panel turns on. The reserve amount is at least 5 liters. The car must be fueled with gasoline whose octane number is in the range of 91-93.

The car has a number of refueling tanks that the owner must monitor during operation:

brake system with expansion tank, total capacity - 0.515 l;
hydraulic clutch drive with expansion tank - 0.2 l;
2 plastic tanks with a volume of 2 liters each contain a supply of windshield and rear window washer fluid.

The clutch release drive and brake system are filled with hydraulic brake fluid (the most popular is DOT-4). It should be changed at least every 3 years, because the liquid has the ability to absorb water vapor contained in the air. As a result, all steel parts of the system in contact with it begin to corrode, which leads to complete or partial failure of the brakes.

If there is a leak in the clutch or brake system, the level in the expansion tanks decreases, so constant monitoring is required over them.

The level of brake fluid in the reservoirs must be maintained no lower than the corresponding mark on the plastic body of the container.

Liquid or clean water for washing glass is added if necessary; in winter, a non-freezing option is required. Otherwise, the ice will not only destroy the tubes, but also damage the electric pump.

Various thick lubricants are also used for maintenance and lubrication of the Niva:

Litol - a composition for lubricating highly loaded bearing parts;
CV joints-4 - lubricant for the hinges of the front axle shafts and door opening limiters;
ShRB-4 is designed for processing ball joints and steering rods.

The list of refueling containers is useful for novice car enthusiasts who bought a used car with a lost instruction manual. The operation of such a car should begin with the replacement of all fluids and oils.
