Replacing the cooling system pipes of a VAZ 2114 video

As with any car, a moment arises when it becomes necessary to replace the pipes of the ventilation and heating system of the car interior. Malfunction occurs for various reasons. Pipes get cracked due to frequent temperature changes. Sometimes the ingress of oils and gasoline also leads to malfunction. Usually cracks and holes form in the pipes under the fastening clamps. If the pipes are of poor quality, a sharp increase in pressure in the cooling system (ICE) of the car engine also leads to malfunction of the pipes.

Saving tip

There is a need to replace the pipes with new ones. You should not spend money on new pipes manufactured specifically for the cooling and ventilation system of the VAZ2115. In a year they will crack and tear. It is better to buy a heater hose from a gazelle car with a diameter of 16mm. A 3 meter long hose will be sufficient. According to the outer diameter of the hose, clamps are purchased for mounting on fittings.

Buying pipes from hand or on unverified Internet bulletin boards can result in untimely breakdown or bursting of the installed pipes, which in turn will make it impossible to cool the engine while running; the consequences can be the most dire. You should purchase original parts or analogues through trusted sellers; if there are none nearby, modern technologies allow you to find the necessary pipes and place an order via the Internet. The main sellers of spare parts for VAZ cars are stores such as Lada-Detal (lada-original.ru - original parts), zaphastivaz.ru (analogues and original), Exit (exist.ru original and analogues), lada-autodetal.ru and others online stores. Before purchasing online, you need to check the store’s reviews and legal details of the store.

To replace faulty pipes, the machine is placed on an overpass, in an inspection hole. The car engine must cool down for at least an hour.

Cooling system design

When the engine is running, a lot of heat is generated for removal, which is used by the car’s cooling system, consisting of the following components:

1 - Heater radiator.
2, 3 - Outlet, underwater pipes of the heater.
4 - Pump hose.
5 - Pipe coming from the expansion tank.
6, 12 - Steam removal hoses.
7 - Tank cover.
8 — Expansion tank.
9 - Thermostat.
10, 19 - Outlet pipes.
11, 13 - Supply pipes.
14 - Cooling radiator.
15 — Radiator drain plug.
16 — Radiator blower fan.
17 - Pump

You need to drain the coolant from the system. Open the expansion tank cap. Remove the sides of the instrument panel in the cockpit. Open the liquid supply valve to the stove radiator. Drain the coolant into a 10-liter container by loosening the clamp on the liquid supply to the stove radiator and disconnecting the pipe itself. In this case, you need to be careful not to let the coolant get into your eyes. Direct the end of the pipe into the container, since the liquid from the container, after replacing the pipes, will need to be poured back into the cooling system. For ease of operation, remove the air filter.

First remove the external pipes, then the pipes from the stove radiator in the cabin. The heater hose is cut to fit the size of the nozzles. For ease of fitting onto the fittings, lightly lubricate the surface of the fittings with grease or lithol. First, attach the hose to the fittings of the stove radiator, then to the tap tubes, not forgetting to first put clamps on the hose. Clamps secure the hose to the fittings and tubes. The same actions are performed on the outside of the pipes and fittings. After assembly, check the tightness of the hose clamps on the tubes and fittings.

Pour coolant into the expansion tank, only up to the maximum mark, and replace the air filter. The expansion tank cap is closed. Start the car and warm it up until the cooling fan comes on. Check to see if there are any coolant leaks from the cooling system. With proper repair, there are no leaks. If necessary, add coolant to the reservoir until the average level between the minimum and maximum marks is reached.

What are the advantages of ordering pipes and other auto parts online?

First of all, I would like to note how convenient it is to sit on the couch at home and choose the necessary auto parts for your car. It doesn’t matter what the weather is like outside at that moment. In addition, using the Internet it is possible to buy parts for cars at work. This is explained by the fact that ordering goods online does not require much time. A few clicks of the mouse and products from the virtual car store will be ordered, all you have to do is wait for it to be delivered.

The catalog of auto parts in the online store is placed on a large number of pages, where the buyer is offered an incredibly wide selection of parts. But don’t think that it’s difficult to find the necessary spare parts in such stores. No, this is absolutely not true, things are somewhat different. Easy search is provided to every user, because the online store has a search system. Thanks to its work, those details that a motorist needs will appear before his eyes in just a few seconds. All you need to do is enter their name in the space provided.

It makes no difference what make and model of the car. There are auto parts for all cars on the Internet. This purchase is beneficial for those who value their time. If necessary, it is always possible to order auto parts from any city. There is no need to worry about their delivery, because this is handled by the courier service. Usually the goods are delivered to the buyer as quickly as possible.

It doesn’t hurt to note that in the online store you can purchase not only auto parts, but also accessories. Their range is huge, so anyone can find exactly what they need.

In conclusion, it remains only to clarify that the cost of parts in virtual stores is affordable. The car owner will not have to worry about this. When making a purchase in this way, he will have the opportunity to save money.

The engine cooling system is of great importance, since without it the engine will overheat and will be unsuitable for further operation. Therefore, the serviceability of this system is very important in a car, and keeping it in good condition is simply necessary.

Engine cooling radiator

Scheme and design 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.

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.

Malfunctions in the cooling system

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:

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).

Which heater tap to choose?

When an old part wears out, it is logical to purchase a modified version of it to prevent problems in the future. Regulator options with metal and ceramic parts are now available for sale. They are more durable and resistant to temperature. Let's consider several options:

A modified spare part from AvtoVAZ with article number 21080-810115000 is available in stores at prices ranging from 180 to 250 rubles . Low price, presence of metal elements, average quality;
A ceramic faucet from Luzar with article number 2108-8101150 is sold at a price of 300 to 500 rubles . High quality, ceramic elements, average price;
The Tsn-Citron company, with article number 8.5.2, offers a budget option for 170 rubles. Medium quality. There are metal elements.

We recommend that you do not save on purchasing a new element of the heating system, because... its unexpected failure will bring a lot of problems.

Radiator repair or replacement

Let us consider in detail the features of the work.

Flushing

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.

Replacing pipes

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 simple (you can apply sealant to the joints)

Over time, various deposits are created in the engine cooling system, which is a consequence of the use of low-quality coolants (coolants). This leads to contamination of the channels, and in general to disruption of fluid circulation throughout the cooling system. As a result, the engine starts to heat up, the heater doesn’t heat up, etc. This photo report is dedicated to self-flushing the cooling system on VAZ 2110-2111-2112 cars

To clean the cooling system, you need to drain the liquid and fill it with distilled water with a special additive, for example Hi-Gear.

Then let the engine run for a while and drain the water along with dirt and deposits.

To completely flush the engine cooling system, you need to:

Flush the radiator. To do this, drain the coolant system, then disconnect the hoses from the base and upper radiator tank. Insert a garden hose into the top hose of the radiator, and run water through the radiator until water comes out clean from the hose at the base of the radiator.
Flush the engine. Insert a garden hose into the thermostat outlet and run water through the motor until water comes out clean from the bottom hose.
Flush the heater radiator. Open the heater tap and disconnect the hoses from the heater. Connect a hose to one of the fittings and rinse with a stream of clean water until water flows out clean from the other fitting.

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.

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.

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.

Stove (heater) pipes for VAZ 2114 “BRT” (4 pieces) No. 87i are original pipes that will last the required period. Planned replacement of pipes 3 - 4 years.

Removing air from the cooling system

Often during repairs, air enters the cooling system, which forms an air lock and interferes with the normal operation of the entire system. In order to remove such a traffic jam, there are several ways. Simplest:

warm up the engine to operating temperature and turn it off;
unscrew the coolant pipe clamp on the throttle body;
remove the heating pipe of the throttle assembly, bleed the air and after the coolant begins to flow out, put it back on the fitting and tighten the clamp.

ATTENTION: the leaking antifreeze has a temperature of more than 90 degrees Celsius.

Thermostat problems

When the temperature reaches 95 degrees Celsius, the liquid begins to flow through the thermostat. Due to the operation of this unit, the engine requires a minimum of time and resources to warm up. The thermostat is located between the radiator and the engine.

Most often there are two types of faults.

The valve closes. If the engine is not warmed up, it is difficult to maintain speed. It may simply stall.
The valve opens. During frosty periods, you can operate the car, but you must turn on the heating at maximum speed. Otherwise, the power unit will simply overheat.

If you are unable to move the valve while repairing the thermostat, don't be afraid to lightly tap the housing with a simple screwdriver. This will solve a common problem.

When the thermostat is completely disassembled, the pipes are hermetically sealed, which will prevent coolant leakage. Only after this can you start working.

In general, the choice between antifreeze and antifreeze should not be a problem for you. Choose antifreeze. Although it is more expensive, it lasts longer and allows you to minimize possible problems with wear and tear of the cooling system. The imaginary savings due to antifreeze are not called that for nothing. In the future, you will pay much more to fix the damage caused by the use of antifreeze.
