How to drain antifreeze from a Chevrolet Niva? - Car repair

Replacing coolant in Niva Chevrolet: how to drain it and what is better to fill with antifreeze or antifreeze?

Antifreeze is a special liquid that is designed to maintain the operation of a vehicle's cooling system and which does not freeze at low temperatures. Using the presented liquid, the car engine is cooled when necessary. Apart from its main purpose, antifreeze also lubricates the inside of the cooling system of a Chevrolet Niva car, which helps prevent the formation of corrosion.

The car cooling system is designed to maintain the optimal temperature of the engine of a Chevrolet Niva vehicle. When the car engine heats up, antifreeze comes into action, with the help of which the vehicle engine returns to the optimal temperature.

The coolant should be replaced according to the instructions specified in the operating manual for the Niva Chevrolet vehicle.

This article will provide information on the procedure for replacing antifreeze yourself, without resorting to the help of specialists, and will also discuss in detail the stages of draining the refrigerant, flushing the cooling system and filling in new coolant.

Until the engine temperature of a Chevrolet Niva car is low, the cooling system thermostat is closed, and the coolant circulates in a small circle without entering the vehicle radiator.

In a situation when the engine temperature of a Chevrolet Niva car reaches approximately 85 degrees Celsius, the thermostat opens slightly and antifreeze enters the car’s radiator. If the vehicle's engine reaches 105 degrees Celsius, the thermostat opens all the way and heated coolant enters the radiator, warming up the interior.

After completing these steps, the antifreeze returns to the pump. The engine temperature of a Chevrolet Niva car is determined using a special sensor.

Types of coolant

Antifreeze is a liquid that is a mixture of pure distilled water, propylene glycol and various additives. Water is used as a universal solution, and propylene glycol makes the liquid viscous and sticky. Additional additives provide better engine cooling and also perform a number of additional functions depending on the composition:

silicate additives prevent metal oxidation and also reduce the overall temperature of the liquid;
carboxylate additives destroy fatty deposits on the walls of the cooling system channels and also increase the shelf life of antifreeze;

antifreeze with special additives on sale , which can perform a number of specific functions - they prevent the liquid from freezing at subzero temperatures (relevant for cold regions), eliminate scale and foam (relevant for old problematic engines), and so on.

Start draining liquid

To do this you will need to do the following:

The hood must be raised and firmly secured in this position.
Unscrew the cap of the expansion tank. You should not rush into this - heated air must come out of the tank, then the pressure inside will decrease. The cover is then removed completely.
The plug is unscrewed from the drain hole. The working fluid should come out. It is advisable to place a container nearby in advance so that all the used antifreeze from the Chevrolet Niva goes there and not on the ground.

To avoid air plugs in the system, you will need to discard the plug tube from the throttle assembly. To do this, it is necessary to use a screwdriver to loosen the fastener, and the latter subsequently moves posteriorly. This allows such a procedure to be carried out.

Recommendations for choosing for Chevy Niva

To determine which antifreeze is best to pour into your Chevrolet Niva, you need to know which one was filled from the factory, since each model has a lot of specific nuances. However, in most cases, the choice of coolant depends on the year of manufacture of the car:

for older models that were produced before 2001-2002, class G12 fluid is suitable;
for later models (from 2003 to 2010), G12+ antifreeze is suitable;
for modern models (manufactured after 2010), it is recommended to purchase coolant category G12++.

Also, many people use the domestic mixture Antifreeze class TS-40 as antifreeze. Motorists often speak negatively about Antifreeze, but in its properties this liquid is practically no different from foreign antifreezes. To understand the absurdity of negative reviews, you need to remember that most Chevrolet Niva cars are filled with antifreeze at the factory.

The only major drawback of antifreeze is its shorter service life in comparison with G12 mixtures - in this the domestic cooler is really inferior to its foreign analogues. The recommended replacement frequency is 30 thousand km, and for some antifreezes the interval between replacements can be up to 200 thousand km.

To find out more information, watch the video in which an expert answers the question of what is better - antifreeze or antifreeze:

How to choose antifreeze?

The creators of this car have already made sure that you don’t have to choose anything; all the necessary brands of coolers are described in detail in the additional instructions. All you need is to remember basic safety rules that will help you avoid harming yourself or your car.

Replacing antifreeze is a preventative action that should be carried out periodically not only in winter, but also in summer, periodically adding the necessary fluids so that the car always functions well.

Replacement procedure

After choosing the type of coolant, we will consider how to change antifreeze in a Chevrolet Niva.

Required Tools

First you need to find an inspection ditch or lift to access the car from below.

Now you need to prepare the following tools:

wrench 10;
pliers;
flat screwdriver;
funnel for filling a new cooler;
container for draining old fluid (volume of at least 8 liters);
distilled water (if required).

Next, let's look at how to drain antifreeze with your own hands:

Turn off the engine and wait until the system cools down completely.
Open the hood, find the expansion tank and remove the cap from it. The lid should be unscrewed gradually, as hot air may accumulate under it.
Find the drain hole and place a container over it.
Remove the drain plug and wait a while for the old fluid to drain out of the tank.

For a more visual representation of the process, we recommend watching the video:

How to drain antifreeze from a Chevy Niva

Replacing antifreeze on a Niva Chevrolet car must be carried out taking into account the strict frequency established by the manufacturer - once every 40,000 km, or (if the car owner rarely uses the car) every two years. At the same time, it is necessary to check the antifreeze level and replace it if it darkens or appears brown. Also, replacement of antifreeze may be necessary if the composition does not meet the required density or repair of the engine (cooling system elements) is required.

Which antifreeze is better, and how much to fill in a Chevrolet Niva?

To fill the cooling system you need 10 liters of high quality antifreeze (antifreeze). When choosing a suitable composition, you should focus on the recommendations of the manufacturer and the experience of servicing Niva Chevrolet vehicles. Let's look at the best options:

Cars manufactured in 2002 are suitable for red antifreeze class G12. It is advisable to give preference to G-Energy or MOTUL Ultra.
For cars manufactured from 2003 to 2009, the best choice is red antifreeze class G12+. Options - Lukoil Ultra, G-Energy, MOTUL Ultra, Havoline, Frostschutzmittel A.
In Chevrolet Nivas produced since 2010, it is better to use red coolant G12++, namely products from the brands FEBI, Freecor QR, Frostschutzmittel A, VAG.

How to change antifreeze on a Chevrolet Niva

Initially, antifreeze is poured into the Chevrolet Niva cooling system from the factory, the service life of which is extremely short. And also the composition and additives used are much inferior in quality to modern liquids made on a carboxylate or polypropylene glycol base. Therefore, many car enthusiasts prefer to replace it with antifreeze, which better protects the cooling system, when replacing it for the first time.

Stages of replacing Chevrolet Niva coolant

When switching from antifreeze to antifreeze, it is necessary to flush the cooling system. This is done so that the new liquid does not lose its properties when mixed. Also, due to the different chemical composition, a precipitate or flakes may form. Therefore, the correct procedure between draining and filling should include a flushing step.

This model is quite popular, so many people know it under other names:

Chevrolet Niva;
Chevy Niva;
Shniva;
VAZ-21236.

We will consider the instructions for replacing the coolant using the example of a 1.7-liter gasoline engine. But there is one nuance: cars after the 2021 restyling have electronic control of the gas pedal.

Accordingly, there are no pipes for heating the throttle valve. Therefore, we will consider bleeding air on this modification. You can also familiarize yourself with the nuances of replacement on a regular Niva 4x4, the replacement on which we also described.

Coolant drain

To drain the antifreeze, you need to place the car on a flat surface, open the cap of the expansion tank and wait a little until the temperature drops below 60°C. For further convenience, remove the decorative plastic protection on top of the engine.

Further in the instructions we are recommended to turn the temperature regulator to maximum. But it is useless to do this. Since the temperature control in the Chevrolet Niva occurs by moving the air damper. And not by blocking the radiator as in old VAZs.

After the machine has cooled down a little, we begin the draining process itself:

If you stand in front of the car, at the bottom right, there is a plastic valve on the radiator that closes the drain hole. We unscrew it to drain the antifreeze from the radiator (Fig. 1). When unscrewing, try not to lose the rubber O-ring. Fig. 1 Draining the radiator
Now you need to drain the coolant from the engine block. To do this, we find the drain plug, which is located on the block, between cylinders 3 and 4 (Fig. 2). We unscrew it using a 13mm wrench or use a socket with an extension. For more comfortable work, you can remove the spark plug wire. Fig. 2 Draining from the engine block

In this way, we completely drained the old fluid, but in any case, a small part still remains in the system, distributed among the engine channels. Therefore, in order for the replacement to be high-quality, we proceed to flushing the system.

Flushing the cooling system

If the Chevrolet Niva cooling system is not clogged, but is simply undergoing a scheduled replacement, then we use ordinary distilled water for flushing. To do this, close the drain holes and pour distilled water into the expansion tank.

Then close the tank cap and start the engine. We warm it up until the thermostat opens to flush both circuits. Next, turn it off, wait for it to cool and drain the water. To achieve a good result, it is recommended to do this procedure 2-3 times.

If the car system is heavily contaminated, it is recommended to wash it with special chemical solutions. For these purposes, washes from well-known brands, such as LAVR or Hi Gear, are suitable. Recommendations, as well as instructions, are usually printed on the back of the container with the composition.

But, as far as I know, we don’t have a tap as such, and this knob simply controls the air damper. Therefore, you don’t have to open it.

In general, decide. We release excess pressure in the cooling system by opening the reservoir cap, then tightly close the reservoir cap to reduce the intensity of antifreeze drainage.

Replacing Chevrolet Niva coolant

We place the container under the drain plug on the radiator, located on the driver's side in the lower corner of the radiator, unscrew it and drain it, slowly unscrewing the tank cap. The drain plug is unscrewed and tightened by hand. Unscrewing the radiator plug Be careful not to lose the rubber O-ring of the radiator drain plug, see.

Radiator plug and drain bolt It is also best to avoid contact with antifreeze, as it has toxic properties. It should be between the maximum and minimum marks.

After completing all the work, you need to check the system for leaks and fix it if found. After several days of operation, you need to check the coolant level. If necessary, add antifreeze. In addition, you need to evaluate the color of the liquid; if it turns brown, it means a counterfeit product was poured.

The process of replacing coolant on Niva Chevrolet

In this case, you will have to repeat the coolant replacement. During operation, you need to monitor the level of antifreeze in the expander and not allow it to drop below the minimum, this will lead to overheating of the engine and is fraught with big problems.

Replacing coolant Niva Chevrolet. Do you have any questions? Antifreeze 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.

Antifreeze or antifreeze? Replacing coolant Niva Chevrolet

Tools Required First, you need to find an inspection pit or lift to access the car from below. Now you need to prepare the following tools: In addition, if the coolant has changed color to reddish, replace it immediately, since such a change indicates that the additives have worn out and the liquid has become aggressive towards the parts of the cooling system .

Replace coolant only when the engine is cold. The crankcase protection and mudguard may not be removed, but in this case you will have to use some kind of device to collect the drained liquid, otherwise it will inevitably spill across the area under the car.

The indicated action is performed in order to avoid getting burned by hot liquid or steam.

The expansion tank cap must be unscrewed carefully. First you need to unscrew it a little to release the pressure from the tank and allow hot air to escape. Next, the lid is unscrewed completely; The next step is to unscrew the plug on the drain hole and drain all the antifreeze.

When the used refrigerant has completely drained, the plug must be screwed back into place; In order to prevent an air lock from forming in the cooling system when replacing antifreeze on a Chevrolet Niva car, the car owner needs to disconnect the hose from the fitting of the Chevrolet Niva how to drain the coolant video unit.

You can carry out the presented action using pliers or a screwdriver. The owner of the car should loosen the fastening on the clamp and move it. Next, you need to disconnect the hose from the throttle assembly fitting; The above actions will not allow the car owner to completely drain used antifreeze from the cooling system.

This is due to the fact that a certain part of the coolant remains in the radiator. To get rid of the remaining refrigerant, the car owner should disconnect the lower pipe from the radiator device, instead of which it is necessary to connect a hose of the appropriate diameter.

After it is installed, you need to blow intensely into its other end. Using the presented action, the owner of a Chevrolet Niva vehicle will be able to get rid of the antifreeze remaining in the radiator and the middle main pump.

After replacing the coolant on a Chevrolet Niva, tighten the reservoir cap tightly, because when the car warms up, pressure will be created in the system with antifreeze. The drain plug is sealed with a rubber ring.

To drain antifreeze on a Niva, place the car on a flat surface and open the hood. In the cabin…

Diluting the concentrate and adding new antifreeze

It is necessary to pour new antifreeze into the expansion tank according to a certain algorithm, which will be presented below.

Filling new refrigerant into the cooling system of a Chevrolet Niva car is carried out as follows:

If the owner of a Chevrolet Niva vehicle uses concentrated coolant, then it must be diluted with distillate. The ratio according to which the indicated liquids should be diluted is specified in their instructions. In most cases, this is one to one, but it should also be noted that the refrigerant in the expansion tank must be at least 40%. Before starting to fill in antifreeze, the vehicle owner should make sure that all lines and pipes are in optimal condition. You also need to check that the clamps are sufficiently tightened;
The finished mixture is poured into a reservoir intended for antifreeze, namely into the expansion tank. It is necessary to fill the container slowly to prevent the formation of an air lock in the vehicle’s cooling system. The refrigerant is filled almost to the maximum level;

Filling with antifreeze

At the next stage, you need to make sure that the places where the thermostat connects to the cooling system pumping device, radiator and pump are sealed. In most cases, a white coating appears in the areas where leaks occur. In addition, if faults are detected in the main line, they should be eliminated;
Afterwards you need to close the cap of the expansion tank, which is located in the engine compartment, well. Next, the car owner needs to start the engine of a Chevrolet Niva car and let it run at high speeds for a certain time, waiting until it warms up;
After the car engine warms up, the temperature control sensor should signal the activation of the ventilated device. At the presented stage, it is possible to turn off the engine of a Niva Chevrolet vehicle, after which you need to check the refrigerant level in the expansion tank again. In a situation where the car engine is hot, the volume of coolant should be slightly less than the maximum, but more than average;
Next, the car owner needs to once again start the engine of the Chevrolet Niva, which in the presented case should operate at medium speed. This action helps to get rid of air in the car’s radiator unit;
Radiator of a Chevrolet Niva car
At the final stage, it is necessary to turn off the vehicle’s engine, and then wait until its temperature drops to the optimum. After the car engine has cooled down, you need to check the antifreeze level, which should not be below the minimum mark. In a situation where the above actions were performed correctly, the temperature control sensor should show 80-90 degrees Celsius.

What kind of coolant is filled in the Chevrolet Niva from the factory? – Taxi Bolt

Prudent car owners ensure that their car runs smoothly. All systems must be normal: power, ignition, cooling and lubrication. During operation, a large amount of heat is released from the motor.

To prevent it from overheating, it is necessary to maintain the recommended temperature. This function is performed by a special coolant (coolant).

How to choose coolant?

The selection of coolant should be approached responsibly. Making a choice right away is not so easy. Today, stores offer a large selection of canisters and bottles of various colors and compositions.

The question is brewing: what to fill - antifreeze or antifreeze? What does the manufacturer recommend?

Types and properties of coolants for cars

The best option for effectively lowering the temperature is antifreeze. This is a liquid that contains :

distilled water;
ethylene glycol or propylene glycol (less aggressive substance);
additional additives.

Antifreeze based on ethylene glycol. Additives, in turn, are divided into the following subtypes:

silicate;
based on organic acids (carboxylate);
hybrid antifreezes (based on the two described above).

Carboxylate coolants have good heat transfer and high cooling temperatures . They reliably fight fat deposits and have a longer service life. Silicate antifreezes perfectly prevent corrosion and reduce the temperature of aqueous solutions. They are considered universal.

Carboxylate coolant after 60,000 km.

Depending on the additives used, a high-quality coolant must have a high boiling point and thermal conductivity. Also not to be exposed to freezing in the winter season, maintaining its performance. Do not form scale or foam.

What coolant is recommended for the Niva Chevrolet car

In general, both G12 type antifreeze and antifreeze are suitable for the car .

Many car owners mistakenly claim that antifreeze is a cheap and lower quality version of antifreeze. Modern antifreeze manufacturing technologies make it possible to compete not only with domestic, but also with foreign coolant manufacturers. The only significant difference is the shorter service life of antifreeze compared to antifreeze.

In the Chevrolet Niva, coolant replacement is done as standard - once every 2 years, or every 60 thousand km . Another factor indicating the need to change the coolant is a change in its color. It acquires a reddish tint, which indicates a change in chemical properties.

https://www.youtube.com/watch?v=7WwNaWrBJsI

On cars with air conditioning, it is better to use G12 antifreeze . Usually the plant fills it with TOSOL TS-40 (manufacturer: Dzerzhinsk). Mixing different types of coolant is prohibited. An exception for topping up is FelixProLonger liquid (from the same manufacturer).

What means can you use to effectively flush a stove radiator?

Most car owners are interested in what kind of detergent composition to rinse the heater heat exchanger in order to maximally free its channels from various deposits and contaminants. Naturally, ordinary water is not suitable for this. The principle of cleaning a stove radiator is precisely based on filling its channels with a liquid substance that can destroy and clean the deposits of scale and corrosion that have formed on the walls of the lines. Such means include:

flushing compounds for cleaning the cooling system,
household descalers,
citric acid, vinegar,
soda solution or whey,
carbonated drinks like Coca-Cola.

We recommend: German ZF gearboxes on KAMAZ trucks

It should be noted that when starting the process of self-washing the Nexia stove, it is necessary to take into account the properties of the heat exchanger material. Alkali solutions are absolutely not suitable for flushing aluminum radiators, as they cause an instant metal oxidation reaction, significantly worsening the situation. A similar reaction will occur if an acid solution is poured into a heat exchanger made of copper.

One of the effective means for flushing the radiator of the Daewoo Nexia stove is a solution of citric acid in hot water.

How to check antifreeze using a hydrometer The density of antifreeze is checked using a special device - a hydrometer. Do you have any thoughts on this matter? For all the actions taken you need to have:

Tip 1: How to replace antifreeze in Niva. It is recommended to pay attention to the condition of the antifreeze every six months. ...

And this will lead to frequent repairs of the cooling system. I wish you all successful washing!

To prevent this from happening, every motorist should know where to add antifreeze. This must be done carefully and very carefully. For example, in a VAZ it can be found directly under the driver’s seat, namely on the left side of the engine compartment.

First you need to unscrew it a little so that hot air comes out and release the tank from pressure, and then unscrew it completely.

Now unscrew the plug on the drain hole and drain all the liquid. When the used antifreeze has drained, screw the plug back into place.

Parts and consumables:

To prevent the formation of air plugs in the cooling system, you need to disconnect the hose from the throttle body fitting. To do this, use a screwdriver or pliers to loosen the fastening on the clamp and move it back.

Then disconnect the hose from the throttle assembly fitting. Before adding coolant, it should be prepared.

Replacement frequency, what antifreeze to fill

In the maintenance information for Niva Chevrolet, it is recommended to change antifreeze every 60,000 kilometers. But many car enthusiasts are not happy with the flooded antifreeze, which becomes unusable by 20 thousand. Dzerzhinsky antifreeze is usually filled from the factory, but there is also information about pouring red antifreeze.

When choosing coolant, it is better to use a concentrate rather than a finished product. Since it can be diluted in the required proportion, because after flushing there is still some distilled water left in the system.

A good choice would be Castrol Radicool SF concentrate; it is what dealers often recommend for use. If you choose ready-made antifreezes, then you should pay attention to the red AGA Z40. FELIX Carbox G12+ or Lukoil G12 Red with good reviews.

Antifreeze or antifreeze? Replacing coolant Niva Chevrolet

Replacing the coolant is an integral part of maintaining any car. Every owner of a Chevrolet Niva needs to know how and what kind of fluid needs to be filled.

Replacement frequency

The cooler on a Chevrolet Niva should be replaced according to factory standards. On average, you need to replace it every 40-60 thousand kilometers, depending on the model. In some cases, you need to fill the coolant more often, for example, if the engine life is approaching a major overhaul, or the antifreeze has turned brown or black.

Important: If you use your car very rarely, you should fill it with antifreeze at least once every 3-4 years.
