Engine cooling system VAZ 2115 engine. Features of the cooling system design. Why do air traffic jams arise

ATTENTION

The coolant level must be checked only in the cooled engine. If you remove the Her Iron from the hot engine radiator, then the pressure in the cooling system will fall, while the temperature of the coolant can be at this moment above its boiling temperature at normal atmospheric pressure. Remove the Her Items under these conditions means discarding the pressure in the cooling system to atmospheric - as a result, the coolant will instantly boil. The boiling liquid pairs will break out of the neck of the radiator, splashing in all directions. Not only is the coolant part of the coolant, but the cooling fluid is heated to a high temperature, escaped from the neck of the radiator, can lead to injuries and burns.

Replacing the coolant is performed periodically.

The cooling system is of great interest among motorists. Machines models 2115 have a hidden cooling system based on the use of a special mixture for cooling. The coolant movement occurs under the influence of a mechanical pump.

The principle of assembling many Russian cars is carried out rather not qualitatively, therefore the performance of many mechanisms, including the cooling system, is worse than the best.

To identify and work the necessary repair work, it is necessary to have an idea of \u200b\u200bthe status and method of the cooling system.

Airlock

If you have the engine with a volume of 1.6 liters, then the first thing is to remove the plastic lining on the engine - we unscrew the cover on the engine to fill the oil, and then pull the entire overlay. It is planted on rubber seals. After removing this plastic screen, we spin the oil cover back in order to avoid dirt entering the engine crankcase.

- We find the heating nozzles of the throttle assembly (there are 2 them), see the drawing. Remove any tube

- We start blowing a tank with liquid. I blow until all air from the hose comes out and Tosplan will not be poured.

- Quickly wear the phone back and tighten the clamp, so that the air does not get there.

(It is worth noting that depending on the tube you removed, Tosol can flow from both from the tube; and from the fitting, from where the tube was removed)

The second way to remove air from the cooling system is less perverted. Here you do not need to blow anything:

- Warm the engine to operating temperature

- Warming, wasting engine

- The plug of the expansion tank does not need to be unscrewed.

- as in the first way, we unscrew the coolant coolant clamp on the throttle node.

- After removing the heating nozzle of the throttle node, release the air, and after it starts to leak the toosol, immediately put it back to the fitting and fasten it well with a clamp.

But be careful and careful! Do not forget that the temperature of the cooling fluid is approximately 90 degrees.

There is also a simpler, but less effective way to eliminate air traffic jams:

1) We visit the steep slide so that the radiator lid has become the highest point of the cooling system.

2) We unscrew the lid of the expansion tank and the radiator cover.

3) Let's warm the car to the operating temperature

4) then gas themselves several times and in parallel pour cooling fluid in the bar.

We do as long as the bubbles will no longer appear.

Replacing pipes

In the cooling system, 4 rubber pipes are used:

- the upper tubing pipe - congestives cooled fluid from the radiator to the engine;

- the lower removal pipe - removes the heated fluid at the bottom of the engine to the radiator;

- Two short nozzles that attach to the water pump system and thermostat.

In case of failure, the nozzles must be replaced. It is best to purchase silicone pipes.

To remove old and install new silicone (rubber) nozzles, you must have a set of wrench keys, several screwdrivers and silicone lubricant.

Repair associated with the replacement of pipes must be carried out in this order:

1. Disconnect and remove the battery;

2. merge the entire cooling mixture;

3. Remove the fan, noise insulating upholstery, lining and frame lining from windshield;

4. free access to the air collector, for what to remove the elements of its mounting;

5. Remove the front housing and release the clamps that hold the nozzles;

6. Remove the nozzles from the fittings and install new (silicone or rubber) on their place. Secure new pipes with clamps. Before installing, it is recommended to lubricate rubber pipes with silicone lubrication. Also silicone lubricant is desirable to lubricate the screws of the clamps. Subsequently, it will make it easily unscrewed them;

7. Install all the details taken into place, rinse the system and pour a new cooling mixture into it.

How to rinse

Washing the cooling system with water

Although water and you can wash the system, I would strongly not recommended to do this. As I said, it contains a large number of impurities and salts that form a scale. If there is no other option, then use at least distilled water. Washing the cooling system using distilled water is as follows:

- Fill water in soda.

- Run the motor and let it work approximately half an hour.

- Then shuffled the engine and drain the water from the system. Repeat the procedure until your flushing fluid becomes the same as before washing. The disadvantages of this method include: the formation of scale, low efficiency (boiling water is not able to dissolve and launder and other deposits).

Flushing with acid cooling system with acid and vinegar

Water with vinegar and acid, it is a little better than just water, because thanks to acids can be laundered and produce partial cleaning of the cooling system. In order to rinse the system in this way, prepare: caustic soda, lactic acid and vinegar. The acid is added neatly and slightly, if you can move away with plastic and rubber components of the cooling system. To completely remove scale and dirt need 5-10 hours, during which it is necessary to periodically warm the motor to the operating temperature. At the end, the entire liquid merges and fills the distillate, which produces the finish washing of the cooling system.

Washing soda with special chemistry

Specialist. Funds are the most efficient and expensive option. However, the effectiveness of such a procedure is worth overpaying. In the composition of cleaning products there are special cleaning materials actively removing scale, fat, organic, and so on.

Washing specials. The means are divided into four types: acid, alkaline, two-component, neutral type.

Acid and alkaline are considered the least popular, moreover, they are almost impossible to find them. This is explained by their aggressive impact on the entire cooling system, in the essence of plastic and rubber products.

Two-component funds are very popular and very in demand. Their 2-component solution consisting of alkali and acid copes well with the task. Each component is alternately poured into the radiator.

There are no aggressive substances as part of the neutral means of cleaning the cooling system, such as acids or alkalis, and they are used exclusively in preventive purposes.

The engine cooling system is far from the most secondary element responsible for the normal functioning of the car. Problems associated with the normal cooling of the motor are interested in any car owner. That's about it, and how to improve the work of this element of the car, we will talk in our article.

Disadvantages of the basic cooling system

The main reason for which the refinement of the cooling system of the VAZ 2114 is very often necessary, is the uneven operation of this system itself. So, when the stove is turned on, the heating of the cabin although it happens very slowly (this is especially true for the start of the machine after the parking lot with the motor turned off), but still occurs. But, by reaching the 80 C system, the heating stops sharply and cooling occurs.

The inverse situation occurs in the summer when the fan work shows itself completely unsatisfactory, and to be in the car (if additional air conditioning is not installed) - it is extremely difficult.

All these shortcomings are caused by the imperfection of the cooling system itself, and how to fix them - we will tell below.

What is needed upgrading

It should be immediately noted that the alteration of the cooling system of the VAZ 2114 is not a prerequisite for the normal operation of the car.

The main goal is to achieve maximum comfort in the cabin of the car both in hot and frosty weather. It will help to avoid excessive heat or cold inside the car and will save from sharp leaks of temperature (characteristic, by the way, and all other cars from AvtoVAZ - after all, they have the cooling system for one common principle).

Most likely the reason for the poor performance of the system, many consider the radiator, which is really no high bandwidth, others sin on the pump (and in some cases it happens really).

But, as serious studies have shown, the main reason for the poor performance of the cooling system is its thermostat. After all, it is this detail that is responsible for even water heating and its protection against excessive heating or freezing.

The process of incorporating the thermostat on the scheme below will help to avoid troubles like:

1. Long heating of the cabin after parking.
2. Racing temperature while driving.
3. Poor cooling in summer heat.
4. Uneven heating of the cabin.

How to make upgrading the system

The most simple scheme for refining a cooling system VAZ 2114 is to replace places in the nozzle, departing from the stove and the nozzle departing from the expansion tank. Thanks to such a simple and fast modernization, the following occurs: During its work, the motor motor heats the cooling fluid, which then falls into the thermostat.

From the thermostat, part of the coolant comes to the stove, and the other part is to the pump and from there in the engine (the small circle passes). A part of the liquid received to the stove gives part of the heat and in a somewhat chilled form it enters the thermostat.

The thermostat occurs mixing the coolant received from the stove with a heated liquid coming from the engine. As a result, the total temperature of the fluid is reduced (due to the coolest coolant from the stove) and the valve opening does not occur. Due to this, the thermostat valve will open only when the whole fluid located in it will have a temperature of +85 C.

As you can see, the circulation of the fluid and its temperature in the system will be much evenly and will not have sharp drops, as using the "classic" scheme installed from the factory.

For such a schema, a thermostat with the 6th holes ("new sample") must be installed. If for any reason it is a thermostat with the 5th holes, it should be replaced with the specified one.

Preparing to perform tuning of the cooling system VAZ 2114 according to the above scheme, it should be remembered that when replacing the nozzles in places, their length will be not suitable - one will be longer, and the other is shorter. That is why in order to fulfill the required procedure, you will need to purchase new pipes and adjust them in length or make them yourself.

For all this procedure, you will need a minimum of tools:

• crosshead screwdriver;
• pliers;

Before dismantling nozzles under them, a cloth should be placed in order to avoid spill of the coolant.

Fixing nozzles with the help of clamps, it is important not to apply excessive force. Excess tightening may soon lead to the destruction of the material of the pipe.

Thus, by the upgrades of the cooling system, you can achieve the following results:

1. Even in the strongest frosts in the car, there will be heat (thanks to a more uniform circulation of fluid and increase the efficiency of the stove, on average, by 20%.
2. In the summer heat, the cooling of the salon will be almost 2 times more efficient (after all, the rate of fluid circulation will increase more than 2 times).
3. The operation of the car's motor will become more uniform and smooth, they will disappear characteristic of Vazovsky (and other domestic production machines) "Dips".

In addition to all this, the indicators of temperature sensors will now show the true temperature, exactly the corresponding temperature in the system.

As you can see, very simple and fast (the replacement itself can be performed in a few minutes) the procedure helps to solve a number of serious problems at once. It should also be noted that such tuning can be performed not only at 2114, but also on other VAZ cars.

Cooling system VAZ 2114 causes great interest among motorists. Machines Models 2114 have a hidden cooling system based on the use of a special mixture for cooling. The coolant movement occurs under the influence of a mechanical pump.

The principle of assembling many Russian cars is carried out quite not well, therefore, the performance of many mechanisms, including the cooling system of VAZ 2114 leaves much to be desired.

To identify and work the necessary repair work, it is necessary to have an idea of \u200b\u200bthe status and method of the cooling system.

The engine cooling system of the VAZ 2114 has a big defects, because requires constant control, frequent maintenance and carrying out the necessary repair.

Principles of operation of the cooling system 2114

The functioning indicator is based on internal heat exchange carried out due to the effect of cooling mixture. This option is most effective.

The movement of the cooling mixture is carried out by coercion under the influence of the pump operating from the drive belt. The mixture for cooling is filled into the system by infringing into the extension tank. Depends on the volume of the motor.

The electric fan is installed on the motor shaft, the work is based on the sensor readings, due to which it begins to perform its functions, or stops them.

The VAZ 2114 car uses a hidden cooling system that functions based on a special fluid. The mechanical pump ensures the movement of this cooling composition on the system.

Alas, the quality of the collection of radiator VAZ 2114 and all systems cooling as a whole leaves much to be desired, because over time it may fail. The main minus OS (cooling system) of the "fourteenth" model is the need for constant monitoring, regular maintenance and repair.

The solution of these issues complicates the fact that the circuit of the injector engine cooling system on the VAZ 2114 is rather complicated and includes 28 elements. Get acquainted with them is the most convenient in the special schedule.

The cooling system in the VAZ 2114 operates on the basis of an internal heat exchange, which is carried out under the influence of coolant. It moves forcibly due to the pump, which is activated by the drive belt. The mixture falls into the OS through the expansion tank.

The electric fan stands on the motor shaft. Depending on the sensor indicators, it turns on or disconnected. One of the main elements of the OS is thermostat valve with storage which feels the change in air temperature.

If the fluid temperature is about 87 degrees, the main valve turns on and launches the liquid for a large contour. At a temperature of 102 degrees, the valve will stop 8 mm.

Replacing the cooling fluid

To normalize the cooling system on the VAZ 2114, sometimes it is enough to replace the cooling fluid. To determine when you need to do, you should know some nuances:

• The term of the effective work of Tosola is 2 years, and antifreeze - 5 years;
• Typically, the replacement of antifreeze is required when running 20-40 thousand kilometers, depending on the operating conditions;
• The changed color of the composition indicates that it needs to be replaced.

Specialists recommend using as a liquid antifreezeSince it has a long service life and does not wear the system so intensively. In favor tosola only its affordable price speaks.

Before filling a new liquid, the system should be rinsed. For this:

• Drain all the existing cooling fluid from the system;
• Tightly screw the plugs;
• Pour high-quality distilled water to maximum;
• Drive the engine and bring to the operating temperature;
• Turns should be about 3 thousand. Avoid overheating of the engine;
• Loading the motor, the car is left for about 7 minutes, after which the water is drained. If the system is polluted strongly, the procedure must be repeated until completely clean distillate begins.

Because of what the OS does not work

The cooling system most often ceases to work due to improper operation of the thermostat. You can not do anything but his replacement.

If you do not know which cooling radiator is better to choose for VAZ 2114, look at the existing one. Buy analogue from the manufacturer, or take the device with the most close characteristics.

On the fourteenthest model put an aluminum radiator with two additional tanks. The design of the radiator includes:

• Radiator;
• Top tank with nozzles;
• Lower tank with nozzles.

Replacing the radiator

If there is a need to replace the radiator, remember the priority golden rule - before dismantling the device, the engine must be cold. Because if you just arrived in the garage, let the car stand for a couple of hours. Even better - Leave the car and come tomorrow.

The replacement procedure itself is as follows.

1. Unscrew the plug from the expansion tank and the cylinder and the radiator plug.
2. Drain the coolant into a large container.
3. Disconnect the ventilation system of the radiator from the battery.
4. Remove the silicone pipelines of the cooling system of the VAZ 2114, disconnecting them from the radiator and the tank.
5. Remove fastening bolts from casing.
6. Holding the radiator, get the skin and fan together.
7. So you fully free the radiator, because without problems, replace it with a new one.
8. The assembly of the node is carried out in the reverse order. At the end of the radiator replacement, start the engine, and check the efficiency of the new unit.

Repair of radiator

In some cases, the radiator can be repaired, because you do not have to buy a new spare part.

Preferably, repair work is to eliminate leaks, which arose as a result of the appearance of defects, cracks and sampleins.

Most often, the liquid flows into the joints of the plastic and metal parts. With a small leak, you can pour a special liquid with a cooling mixture inside the radiator. Thanks to a special composition, this tool is bordered by defects that caused leakage. With serious damage, repairs will no longer save the situation, you will have to change the radiator anyway.

To check the tightness of the radiator, you can make a simple experience in the home conditions.

1. Type to the bathroom enough water for immersion of the radiator.
2. Close tightly all holes of nozzles.
3. Lower the radiator under the water by about 30-50 centimeters. Press the pressure of 0.2 MPa.
4. Watch what will happen. If bubbles appeared, the system is not sealed and needs to be repaired or replaced.

Do not even try to repair the radiator after lateral or headile shocks at an accident. In such situations, he suffers first of all, and no closure fluids will no longer help you.

Problems with thermostat

The thermostat sensor is responsible for maintaining the required temperature temperature. It allows you to close the coolant access inside the radiator until the engine is heated to the optimum temperature. It is about 90 degrees Celsius.

When the temperature indicator is reached in 95 degrees Celsius, the liquid starts to go through the thermostat. Due to the work of this unit, the engine requires a minimum of time and resources for heating. The thermostat is between the radiator and the engine.

Most often there are two types of faults.

1. The valve closes.If the engine does not warm, revolutions are held with difficulty. He simply can stumble.
2. The valve opens.In the period of frosts, it is possible to exploit the car, but it is required to include heating for maximum turns. Otherwise, the power unit is simply overheated.

If you fail to shift the valve during the repair of the thermostat, do not be afraid to lightly hit the housing with a simple screwdriver. This will solve the common problem.

With a full disassembly of the thermostat, the nozzles are sealed, which will allow preventing the refrigeration fluid leakage. Only after that you can proceed to work.

In general, the choice between Tosol and antifreeze should not become a problem for you. Choose antifreeze. Though it costs more expensive, but serves longer, it allows you to minimize possible problems with the wear of the cooling system. Imaginary economy due to Tosola is not so called. In the future, you pay much more for the elimination of those damage to which the use of Tosola has led.
