Replacing the cooling system pipes of a VAZ 2114

In cars of domestic manufacturers, engine cooling occurs using a cooling system; in the VAZ-2114, this task is performed by antifreeze. Only with the right choice of antifreeze can you ensure efficient operation of the cooling system:

Factory antifreeze fluid is worse; due to the smaller amount of additives, the thermal protection of the vehicle suffers significantly. Antifreeze was developed specifically to cool vehicle parts and components, so it is exceptionally useful.
Factory fluid has one big drawback - it quickly spoils the pipes, which in turn leads to fluid leakage and radiator defects.

Having convinced himself of how important it is to use high-quality antifreeze, the driver of the VAZ-2114 begins to replace the old fluid with a new one. In this case, after a couple of weeks an antifreeze leak is detected, what’s the matter? The owner of the car did not take into account that along with the antifreeze, the pipes through which leaks occur must also be replaced.

Cooling system pipes VAZ 2114, 2115

The rubber pipes of the VAZ 2114 cooling system are examined in video and photos at the request of Boris Zverev...
Greetings, Lada VAZ car enthusiast on the RtiIVAZ website!

A YouTube channel subscriber came up with the idea to make a video about the rubber radiator pipes of the VAZ 2114 and the heater pipes of the VAZ 2114, just like his car. This video was filmed at the request of Boris Zverev, and the article was edited on the initiative of Albert Aukhadullin.

Let's start with the steam exhaust hose of the cooling system. This hose serves to remove steam from the radiator to the expansion tank. The length of this product is slightly more than one meter, the diameter of the internal hole is 8 mm.

This hose is installed on VAZ 2108, 2109, 21083, 2113, 2114 and VAZ 2115 models with injection and carburetor engines.

On models of the “ten” family, the same hose is installed as in the photo above, catalog number 2110-1303095.

Next we will consider the hoses installed to heat the throttle assembly.

These are inlet and outlet hoses for coolant. The diameter of the hose when measured with a school ruler is about 10 mm, and the length is 48 cm.

Examination

VAZ 2109 replacement of pipes

If there is no inspection hole in the garage, then the car must be placed on an overpass. In bad weather conditions, it is still better to drive it into the garage. Raise it higher with a jack and place reliable supports under each part of the machine.

Note: Never leave your vehicle on a jack for long periods of time.

To work you will need:

tool set;
a lamp with a protective cap - in case of a fall or impact, the lamp will not break, and the fragments will not cause injury;
antifreeze for topping up.

First you need to disconnect the negative terminal from the battery.
Lay a sheet of plywood or thick cardboard on the floor.
It is necessary to start the inspection from the engine compartment and first make sure that the temperature of the cooling radiator and the engine has reached the ambient temperature.

Replacing the cooling system pipes of a VAZ 2109

Check the connections of the pipes on the outlet and inlet fittings of the radiator.
The connections to the thermostat at the expansion tank are also carefully checked.

Note: check with the palm of your hand, running at the bottom of the connections. You need to determine whether liquid is accumulating.

Tighten the clamps, but do not tighten them too much, as you can damage the pipe itself if you overtighten the clamp.
Then lie down on the prepared cardboard at the bottom of the car under the engine and check the pipe, as well as the suitable pipe of the water pump.

Note. Don’t forget to check the pipes that go to the interior heating system.

Then continue checking under the hood.
Rubber tubes suitable for the carburetor are carefully checked.
Don’t forget to check the tightness of the radiator drain plug and coolant temperature sensor.
After completing the inspection, make sure that all inspected connections are tight.
Make a conclusion about the condition of the pipes.

Radiator pipes VAZ 2114

Next comes the upper radiator inlet pipe, connecting the radiator to the engine block head.

This hose goes to injection engines. Its internal diameter is 32mm, see catalog number 21082-1303025.

The next one is the lower radiator outlet pipe, which connects the radiator to the engine cooling system thermostat.

Its catalog number is 21082 – 1303010, internal diameter is 32 mm.

“Angle” pipe for connecting the thermostat to the water pump (pump).

Catalog number – 2109-1303093-01. This pipe fits almost all front-wheel drive VAZ models.

The expansion tank pipe is popularly called the “filler pipe.”

It serves to connect the expansion tank to the thermostat. Through it, antifreeze enters the cooling system when the system is filled or topped up through the expansion barrel. See catalog number 21082-1303080 for its number.

Stove pipes VAZ 2114

The pipe that connects the heater to the block head is often called “big goose” in everyday life because of its resemblance to this bird.

The hose supplies coolant from the block head to the heater radiator. We look at the catalog number 2114 – 8101206.

These considered rubber hoses are reinforced, except for the throttle heating hoses and antifreeze steam exhaust hoses.

The goose curve hose is located under the hood of the car and serves to drain coolant from the heater radiator to the water pump.

Catalog number of the crooked goose 2114- 8101208, factory BRT.

The “short” pipe connects the thermostat to the engine block head.

Shorty catalog number 2108-1303082, BRT plant.

The “small” cabin pipe of the stove supplies coolant to the radiator of the stove, through the tap, from the “crooked goose”.

Its VAZ catalog number is 2114-8101200 from the BRT plant.

The cabin “large” outlet pipe is designed to drain coolant from the heater radiator through the “big goose” hose to the water pump.

Catalog number 2114-8101204 from the BRT plant.

Under the hood, the “big goose” supplies coolant to the heater radiator through a tap. And it takes the liquid to the pump from the radiator of the “goose curve” stove through the “large” cabin hose. For example, thanks to a set of rubber pipes, coolant circulates through the heater radiator.

The rubber pipe, the so-called injection “breather”, serves to connect the valve cover of the block head with the “snail” (2111) for supplying air to the engine.

The upper catalog number of the factory breather is 2111-1014058-10.

All connections presented in the video are located under the hood and in the interior of the VAZ 2114 car, related to the cooling system. In addition to the large breather pipes, small breather pipes and volutes, which serve for the passage of air.

The car also contains well-known gas supply hoses, brake hoses, a vacuum hose, as well as windshield washer fluid supply and others. They will also need to be viewed on video and described in the article.

All rubber hoses in a car need constant replacement, as they are exposed to aggressive liquids and gradually lose their properties. They lose their elasticity, become tanned, crack and sometimes break when used for a long time without replacement.

Therefore, it is recommended to periodically review their condition and replace them if any malfunction is detected.

This video ends the review; I hope that the video will be useful to someone both for information and when servicing their car.

Boris Zverev suggested in the comments the idea of equipping the Lada VAZ 2114 with a set of pipes, for which special thanks. I upload a video about the Renault Logan car on the YouTube channel, since it is my car. You, Boris, have subscribed and write comments about technology. Thanks again for this and respect.

Instructions for replacing the cooling system pipes of the VAZ-2114

Factory antifreeze fluid is worse; due to the smaller amount of additives, the thermal protection of the vehicle suffers significantly. Antifreeze was developed specifically to cool vehicle parts and components, so it is exceptionally useful.
Factory fluid has one big drawback - it quickly spoils the pipes, which in turn leads to fluid leakage and radiator defects.

Experience shows that old hoses are absolutely unusable; antifreeze corrodes them very quickly. Therefore, it’s time to learn how to replace pipes, and finally close the question of the correct operation of the cooling system. Service station specialists will tell you how to implement your plans.

Why does the heater in a Lada Kalina car blow cold air?

Breakdowns are common not only to old, but also to new cars. Some owners of Lada cars notice that the heater blows cold air; Kalina may also be susceptible to this problem. This can happen for many reasons.

Regardless of this, it is better not to delay repairs. Here, as in the human body, one small violation can trigger a chain reaction. You can deal with such a breakdown yourself or in a service station.

Attention to every detail

It is easier to prevent a technical malfunction than to spend time and money fixing it later

In order to avoid having to repair the stove on your Lada (it doesn’t matter whether it’s Kalina or Vesta), you need to carefully monitor the technical condition of the car:

every morning at Kalina’s parking lot, you need to check for dark spots indicating an antifreeze leak;
inspect the system hoses for leaks;
if any are found, then it is necessary to immediately change the tank cap;
daily inspection of the stove radiator;
If the stove blows cold air, then the reason should be sought in increased coolant consumption.

Daily checks of the vehicle’s “health” will help avoid many problems.

If the radiator valve is loose or the coolant reservoir is leaking, the problem will spread at an alarming rate within a short time.

The first result will be a breakdown of the vehicle's computer. Such a malfunction is not covered under warranty, so repairing the heater and replacing the computer will fall entirely on the shoulders of the car enthusiast. A small rearrangement of the on-board computer will help reduce the risk of such troubles for Kalina:

carefully dismantle the cladding;
unscrew 2 screws;
gently squeeze the computer towards you;
place it on a shelf in the glove compartment area;
There is no need to disconnect the wiring harnesses;
fix the computer in a new place;
re-grounding is not carried out.

If everything is done correctly, then in the future the Lada Kalina will not be left without an on-board computer, even in the event of an unexpected problem. The main thing is for the driver to make sure that the fastenings are secure after rearrangement.

Technical specifics of restoration of functionality

In most cases, repairing a heater takes little time. If the Lada Kalina requires one, then if you have the necessary tools, you can do everything yourself.

In order to solve the problem with the stove on Kalina, you need to perform the following sequence of actions:

drain all coolant;
remove the air filter (the heater damper cannot be removed);
the brake and gas pedal are dismantled for more convenient replacement of the radiator;
in some cases there is a need to dismantle the steering structure assembly;
the battery is removed together with the stand;
remove the air duct;
carefully unscrew the hose from the radiator;
The interior heating hose is dismantled.

To save time in the future, it is necessary to fix the position of the parts in space. This will allow you to avoid delaying the repair of the Kalina heater. In some cases, the above algorithm does not work fully. The culprit here is the individual characteristics of the vehicle. In this case, there is no need to rush or start using brute force.

Experienced drivers recommend removing more parts and components of the vehicle, which will ultimately make it possible to replace the radiator and grille.

Regardless of the complexity of the repair, you must ensure that the coolant has been properly drained and then refilled. Any drips and leaks can negatively affect the technical condition of the iron horse.

During repairs, the car owner may notice wear and tear on some parts of the car. In this case, they should be replaced.

Firstly, this will eliminate the risk of repeated repairs. It is impossible to predict exactly when the car will start to feel unwell. Secondly, high-quality operation of the vehicle saves time and money that the driver would have spent on visiting a service station.

How to correctly replace pipes in a VAZ-2114

The first question that experts hear from car enthusiasts is which pipes should be purchased for the VAZ-2114? Products made from silicone are considered the most durable and at the same time ideally compatible with the cooling mechanism of the VAZ-2114. The diagram below shows the location of the pipes we are interested in:

The short ones are mounted on the couplings of the thermostat and the pump pumping water.
Next comes the conductive hose.
The pipe located in the lower part is responsible for removing antifreeze from the radiator unit.

Why the OS does not work

If you don’t know which cooling radiator is best to choose for the VAZ 2114, look at the existing one. Buy an analogue from the manufacturer, or purchase a device with the closest characteristics.

The fourteenth model is equipped with an aluminum radiator with two additional tanks. The radiator design includes:

Radiator;
Upper tank with pipes;
Bottom tank with pipes.

Instructions for replacing the cooling system pipes of the VAZ-2114

Step-by-step replacement of cooling system pipes in a VAZ-2114 car looks like this:

Remove the battery cable that comes out of the negative socket.
Carefully drain the old coolant, but wait until the engine has cooled completely before doing so. Otherwise, there is a risk of getting burns from the coolant.
Remove the following components: set aside the upholstery that provides sound insulation, the fan, the trim going to the windshield frame, the facing material.
Now your goal is to get to the air collector; to do this, unscrew the brackets in the form of springs and the screws responsible for fixing them. A screwdriver is ideal for spring clips; for screws, you need a wrench.
To loosen the clamps, remove the front housing, and then remove the old hoses from the fittings.
All that remains is to install new silicone hoses in a specially designated place; it is preferable that the parts are manufactured abroad - they will last longer.
Reinstall the other components by following the reverse order of this step-by-step instruction.

Subtleties of filling new antifreeze

Before you start filling in new coolant, you need to drain the old one, and also thoroughly clean the entire cooling system of contaminants. To do this, it is better to use a special cleaning agent that can be purchased at a car enthusiast store. Make sure that all taps and plugs of the VAZ-2114 are open. You can determine whether the system has been flushed or not based on the color of the antifreeze flowing out.

The plugs and tap are closed only when the product becomes transparent. If the manufacturer describes in the instructions the specifics of using the cleaning mass, follow these rules for effective cleaning. As for the level of antifreeze filling, some drivers prefer to fill to the limit mark, others deliberately do not top up, and later, after a successful test, add more fluid.

After the antifreeze has been replaced, all that remains is to close the expander and start the car engine. The motor should idle until the furnace fan starts running.

Reviews of silicone pipes for the VAZ-2114 cooling system

Drivers of the VAZ-2114, who replaced the usual factory rubber pipes with silicone ones, note the following advantages of the new components:

Long service life, and all thanks to the increased wall thickness and dense reinforcement, consisting of several layers of material.
Silicone hoses work successfully and efficiently, regardless of the temperature and weather conditions outside.
When the silicone pipe is tightened, a force is felt, so overtightening and damaging the hose, like a rubber one, will not work in any case.
The engine compartment can be painted any color you like.

Among the disadvantages of silicone pipes built into the cooling system of domestically produced VAZ-2114 cars, drivers note:

high cost of parts, one set is approximately 1.5-2 times more expensive than rubber analogues;
the manufacturer does not provide any warranty, so if you bought a defective product, it is impossible to replace it and you will again have to spend money on a new set of hoses.

In order not to pay extra, VAZ-2114 owners prefer to order silicone pipes in online stores, where they are found in 2 types:

with reinforced thread;
Along with silicone there is a rubber component.

Despite the possible negative nuances of silicone hoses, the owners of the VAZ-2114, who took the time to modernize their car and changed the pipes in the vehicle’s cooling system, note that the modification is worth the money - the engine is cooled like clockwork, no major comments are made.

As for the service life of new hoses, on average it is 2 years longer than that of rubber pipes, but only when it comes to reinforced silicone components.

The following video clearly shows how to change antifreeze and flush the cooling system of a VAZ-2114: https://www.youtube.com/watch?v=CGGDk3F1hNY.

The difference between a rubber hose and a silicone hose is explained in the video:

DIAGRAM AND DEVICE OF THE COOLING SYSTEM

The cooling system of the VAZ 2114 is liquid, with forced circulation. Antifreeze or antifreeze is poured into the system as a coolant. In the most extreme case, you can fill it with water, but you can’t drive it for a long time - in winter you can defrost the engine, and during the rest of the season, when the engine is used for a long time on water, the cooling jacket in the block and cylinder head is corroded, and rust accumulates in the radiator.

The VAZ 2114 engine cooling system (SOD) consists of the following elements:

Radiator. It is the main cooling part in the system and performs the function of transferring heat to the liquid into the surrounding airspace;
Water pump (pump). The pump creates forced movement of antifreeze in the system, thereby cooling the entire SOD, including the internal combustion engine (ICE). The pump rotates from the timing belt;
Branch pipes (hoses). Antifreeze circulates through them;
Thermostat. It regulates the passage of coolant through all pipes or only in a small circle and maintains the required operating temperature of the internal combustion engine;
Electric fan. The fan is located on the plane of the radiator and, due to the air flow created, cools its surface when turned on. The electric motor turns on only when the temperature set by the sensor is reached (103°C);
Expansion tank. Liquid is poured into the tank, and when the fan is activated, antifreeze flows into it through the return hose, thereby releasing excess pressure into the SOD;
Expansion tank plugs. There are valves in the plug that relieve excess air pressure created in the system when antifreeze circulates.

Why does the heater on a VAZ 2109 blow cold air at idle?

The cold from the stove in winter is a good reason to stop using your car. The stove is part of the car's cooling system. The antifreeze heats up from the engine and moves into the radiator, which is blown by a fan. Cabin air is distributed thanks to deflectors. The air flow from the fan moves through the heat exchanger and bypasses it. This is the temperature control algorithm.

Possible problems with the stove:

the fan works partially (limited in speed mode) or shows no signs of life;
stove operation is limited in directions;
heating system and temperature controller are in conflict (the stove only blows hot or cold air).

Regularly check the level and quality of antifreeze in your car. A dark orange color indicates that the antifreeze has expired.

COOLING SYSTEM PROBLEMS

As a rule, due to malfunctions in the cooling system, the engine overheats, and this leads to engine failure. Any of the elements may be faulty.

It may leak. Possible leakage through aluminum tubes and plastic tanks. Often the plastic outlet for the return hose of the expansion tank breaks off.
It may clog, and for this reason the engine will heat up.

Pipes. Because of them, antifreeze leaks due to the fact that the pipe:

Ragged.
Old and lost elasticity.

Thermostat. Depending on how incorrectly the valve in the thermostat operates, the internal combustion engine can:

Overheat (in this case, the antifreeze “throws out” through the expansion tank).
Do not reach operating temperature. As a result, the car drives poorly, and in cold weather it is cold inside the car.

Water pump (three main problems):

Noise and play in bearings. It is not worth driving with such a defect for a long time; the pump may jam or fall apart.
Liquid is leaking through the inspection hole. It also signals the imminent “death” of the part.
Broken impeller. With such a defect, the engine overheats very quickly.

A faulty fan also leads to overheating of the internal combustion engine.

The clamps may be faulty or poorly tightened. It happens that thin hoses become clogged with debris (“return”, throttle valve heating).

How the OS works

The electric fan is located on the electric motor shaft. Depending on the indicators of the sensor, it is turned on or off. One of the main elements of the OS is a thermostat valve with a storage tank , which senses changes in air temperature.

If the fluid temperature is around 87 degrees, the main valve turns on and sends fluid through the large circuit. At a temperature of 102 degrees, the valve stops at 8 mm.

REPAIR OR REPLACEMENT OF RADIATOR

Let us consider in detail the features of the work.

RINSE

Replacing the cooling radiator is required if the internal combustion engine heats up due to its clogging. But before changing it, you can try flushing the cooling system of the VAZ 2114 engine. Often flushing helps, and the engine stops heating up. We perform washing as follows:

We park the car on a level surface;
Unscrew the expansion tank cap;
Drain the coolant from the radiator by unscrewing the bottom plug;
We unscrew the water plug from the cylinder block (it is located between the internal combustion engine and the fan in the starter area) and drain the antifreeze from the block;
We wrap the plugs and fill the system with plain clean water;
Let the engine run and drain the water. If the water that comes out is dirty, repeat the flushing. We repeat the procedure several times until the draining water becomes clear;
After flushing, fill in new coolant. It should be noted that the volume of the VAZ 2114 cooling system is 7.8 liters, and if all the antifreeze is not included in the system, most likely an air lock has formed in it. It is necessary to fill the container as much as possible to avoid overheating of the internal combustion engine.

It is often recommended to do the flushing on a cold engine to avoid being scalded by hot antifreeze. On the one hand, it seems to be true, but in cold weather all the dirt will settle on the walls of the SOD, and the washing efficiency will not be so great. And don’t wait every time for the water to cool down. You just need to drain the coolant carefully and work in thick, waterproof clothing and gloves. You also need to remember that the shelf life of antifreeze and antifreeze ranges from 2 to 5 years.

REPLACEMENT

Replacing the cooling radiator on a VAZ is very simple:

Remove the expansion tank plug;
Drain the antifreeze from the radiator and cylinder block. It is necessary to prepare a container for liquid in advance;
We dismantle the air filter housing, it will interfere with removing the radiator;
Disconnect the electric fan plug, unscrew the two bolts securing it and dismantle the unit;
We loosen the clamps where it is more convenient and pull off the pipes;
In the upper part of the radiator, remove the two bolts securing it to the body frame, tilt its body towards the engine and remove the part. Radiator removal is complete;
We reassemble in the reverse order, then fill in antifreeze and start the engine.

REPAIR

If you wish, you can make minor repairs to the engine cooling yourself, but more often they repair it as a necessary measure:

If you need to get to some destination;
In the case when they did not expect a replacement and there is no money yet.

Plastic tanks can be sealed with epoxy resin or soldered; against leakage through the honeycombs, a special chemical composition is used, which is added to the antifreeze and clogs the leaking areas. But it is possible that such chemistry will complicate the passage of coolant throughout the system.

It’s easier not to be tricky with the radiator, but to replace it, especially since it is inexpensive, somewhere from 1,200 rubles.

Therefore, do-it-yourself repairs often become economically unjustified, and a lot of time is spent on useless “treatment.” True, there are more expensive copper radiators, but they are easier to repair - copper can be soldered.

Repairing the thermostat is hardly advisable; it is better to replace such a part immediately. Moreover, it costs about 350-500 rubles.

REPLACEMENT OF PIPE

Replacing the pipes of the VAZ 2114 cooling system is very simple - drain the coolant, loosen the clamp and replace it. In stores, pipes are often sold as a set, and it is also recommended to change them as a set.

Replacing pipes is easy (you can apply sealant to the joints)

VAZ 2114: cooling system and replacement of pipes

The VAZ-2114 car uses a hidden engine cooling circuit with an injector. It is highly complex and includes 28 elements. Traditionally, the assembly of the cooling system of this car is not of high quality. Therefore, throughout the entire period of operation, it requires constant monitoring, regular maintenance and repair. In this regard, many owners of this car are interested in the nuances associated with independent maintenance, repair and operation of the cooling system, among which the most common questions are:

1. How to properly replace the coolant mixture?
2. How to flush the cooling system?
3. How to remove air from the VAZ-2114 cooling system?
4. How to properly replace the cooling system pipes?

Necessary tool

Difficulties that may arise when performing work are associated only with the inconvenient location of the faucet. Otherwise, the replacement process will not cause problems. Before starting work, prepare the following tools and materials:

Pliers for removing stuck pipes;
Flat and Phillips screwdrivers;
New heater valve for VAZ 2114;
A rag for cleaning up smudges and a small container for draining antifreeze;
Canister with new antifreeze for topping up;
A set of wrenches (wrenches 10 and 13 are useful).

To simplify the work, drain the antifreeze from the car radiator in advance. Next, proceed to study the instructions on how to replace the stove tap with your own hands.

Briefly about the car

The VAZ-2114 hatchback is a fairly popular car that can still be found both on domestic roads and on the roads of the entire post-Soviet space. It was produced by AvtoVAZ OJSC from 2003 to 2013 and was one of the variants of the restyled series of the Samara-2 (VAZ-21093) family of cars.

During mass production, various engines with the same type of cooling systems were installed on it, which operate on the principle of internal heat exchange using a special cooling mixture of the “Tosol” type.

Cooling system diagram

Maintenance

Regular maintenance of the cooling system comes down to checking the level of the coolant mixture in the expansion tank and monitoring its color. It is recommended to check before each trip or, in extreme cases, regularly every 500 - 600 km.

The level of the coolant mixture in the tank must constantly exceed the minimum level by 2...3 cm. Checking the level and adding fluid must be carried out only on a cold engine. The mixture intended for topping up must be of the same type as the liquid poured into the system. Mixing different types is not recommended.

IMPORTANT! In the event of an emergency, you can add clean water to the liquid, but the cooling ability of the mixture deteriorates, and the presence of water contributes to corrosion on metal parts. In addition, in winter, the diluted mixture can freeze and damage both the radiator and the engine. Therefore, the coolant mixture diluted with water must be drained as soon as possible and, after repairing and flushing the system, it must be filled with the recommended coolant.

What does damage cause?

The most common cause is engine overheating; failure will occur in a very short period of time. As a result of overheating, the cylinder block becomes deformed, cracks may appear and the piston may become deformed.

But it is much worse when the piston is completely deformed and makes a hole in the cylinder block. Such a breakdown usually leads to a complete replacement of the damaged engine with a new unit.

Flushing the system and replacing the coolant

Repairs related to replacing the coolant on a VAZ-2114 car are carried out if:

The color of the mixture in the expansion tank has changed. This usually happens after 20 - 40 thousand kilometers;
repairs were carried out that required a complete drainage of the mixture.

In general, coolant replacement is carried out in the following order:

1. Completely drain the cooling solution. To do this, you need to open all the plugs and taps, and also remove the radiator and expansion tank caps. Drain the mixture only after the engine has cooled down (In a hot engine, the temperature of the solution can be more than 100 degrees Celsius).
2. Rinse the cooling system with distilled or clean water. Begin the washing procedure after all the old mixture has drained. It is recommended to flush the engine block and radiator with warm water. Otherwise, it is recommended to fill in cold water, warm up the engine, and then drain the water. The color of the water determines how dirty the system is and repeats the flushing process until the flowing water becomes clean. Only after this they begin to replace the mixture.
3. Pour a new cooling solution into the system, having previously closed all plugs and taps. Pour liquid into the tank in a thin stream until the maximum mark is reached. Air pockets are not allowed. Then the expansion tank and radiator caps are closed. In order to prevent the rubber pipes from drying out, they must be lubricated with silicone grease.
4. Start the engine and let it idle until the heater radiator fan turns on. After this, you can turn off the engine and, after cooling, check the fluid level in the tank. If the fluid level has not changed, then everything is normal and the work is completed. If the liquid level in the tank has decreased, you need to make sure by visual inspection that there are no leaks. If they are not there, then add fluid, start the engine again and repeat the test.

Preparation

It is necessary to remove the pipes only when the car engine has completely cooled down. Therefore, if you have just stopped by your garage for procedures, do not rush. It is better to leave the car overnight and return to work tomorrow morning.

Make sure that the pipes are actually damaged and need to be replaced.
Be sure to drain the coolant from the system. If you recently changed it, there is no need to dispose of the liquid. Just use a clean container to drain so you can refill it later.
The order in which you perform the work depends on what hoses are used on your vehicle.

Replacing cooling system pipes

The cooling system of the VAZ-2114 car uses 4 rubber pipes:

upper supply pipe - supplies cooled liquid from the radiator to the engine;
lower outlet pipe - removes the heated liquid below from the engine to the radiator;
two short pipes that connect the water pump and thermostat to the system.

If the pipes fail, they must be replaced. In this case, it is best to purchase silicone pipes.

To remove old and install new silicone (rubber) pipes, you need a set of wrenches, several screwdrivers and silicone lubricant.

Repairs associated with replacing pipes must be carried out in the following order:

1. Disconnect and remove the battery;
2. Drain all coolant mixture;
3. Remove the fan, soundproofing upholstery, trim and frame trim from the windshield;
4. Clear access to the air collector by removing its fastening elements;
5. Remove the front housing and release the clamps that hold the pipes;
6. Remove the pipes from the fittings and install new ones (silicone or rubber) in their place. Secure the new pipes with clamps. Before installation, it is recommended to lubricate the rubber pipes with silicone grease. It is also advisable to lubricate the clamp screws with silicone grease. Subsequently, this will allow you to easily unscrew them;
7. Install all the removed parts in their places, flush the system and fill it with new coolant mixture.

When to change?

Let's remember Soviet times, when all radiators, including products for the heating system, were made of copper. These units had enviable reliability, so replacing the stove radiator was one of the rare procedures, and maintainability was not in doubt. Sometimes it became necessary to clean the cavities of these products from the accumulated scale.

The beginning of the 90s was marked by the appearance of aluminum radiators, which were cheaper. Such units have gained considerable popularity among manufacturers, who still resort to installing them in their new and existing models of cars. AvtoVAZ also professes this trend, heroically equipping the Lada Kalina with aluminum versions of radiators.

The use of products of this type causes a number of problems:

The aluminum product does not have durability and tends to develop leaks after a couple of years of intensive use. Such a case does not involve repair, since it is not possible to eliminate the leak in the product.
Coolant evaporating through a leaking radiator creates toxic fumes that penetrate the cabin, have a sweetish taste and settle on the windows in the form of fogging, similar to greasy stains.
Structurally, the manufacturer placed the on-board system controller under this radiator. If antifreeze gets inside this device, it will fail. Replacing the controller is not cheap, so taking steps to replace the radiator as soon as possible is a good idea here.
Access to the radiator assembly is very difficult, so even such an event as cleaning is a very labor-intensive task.

Among the main reasons causing antifreeze leakage from the heating radiator is the use of cheap antifreeze by Lada Kalina owners. There are plenty of fakes on the market, so careful selection is one of the keys to trouble-free operation of the heating system. Counterfeits contain the presence of various harmful substances that have a negative effect on the aluminum structure, causing leakage.

Today, special sealing substances designed to seal a small leak from the inside have become quite popular on sale.
