Air-cork in the car cooling system

The article will tell you what an airlock is in the cooling system of an internal combustion engine. But first you need to decide what is the cooling system, with its purpose, and also the composition. When the internal combustion engine, at least gasoline, at least diesel, is heated. The temperature of the oil, the cylinder block, rises, as in the combustion chambers there is an explosion of the fuel-air mixture with the release of heat. To date, most engines that are installed on cars have a liquid cooling system. In fact, this is a hybrid system, since during the cooling of the radiator, a counterflow of air or the one that is created by the fan impeller takes part .

Cooling system functions

With the help of the cooling system , the interior of the car is heated. The heating system is included in the cooling circuit. It is thanks to the cooling system that the oil temperature in the internal combustion engine decreases. And if there is an airlock in the VAZ-2110 cooling system, all the work is broken. There is also a decrease in the temperature in the combustion chambers. It is very difficult to distinguish the main element among all the elements, since everything, even the smallest details, affects the effective operation of all systems. But nevertheless it is necessary to note the radiator of cooling which is established in a forward part of the car that on it the counterflow of air got on. With its help, there is a significant decrease in the temperature of the liquid, which circulates through the system.

Elements of construction

Thanks to the design of the radiator, the efficiency of reducing the temperature increases. On all modern cars, an electric fan is installed on the radiator, which is switched on by means of a sensor. This device does not work constantly, but only if the permissible temperature level is exceeded excessively. But it does not function properly if there is an airlock in the cooling system. "Kalina" has the same design of the cooling system as most front-wheel drive cars VAZ. On some machines, impellers with forced rotation were previously installed. In particular, on vehicles of the VAZ classic series such devices were mounted. They were attached to the rotor of the water pump. Of course, without forced circulation, cooling will be very bad. For this purpose, a pump is provided in the structure. With its help, the liquid is pumped in the required direction. In total there are two radiators in the system: one is installed in the car, it is somewhat smaller, but it is enough to heat the air. The second, the main, as already mentioned, is in the front of the car.

Cooling circuits

In the podkapotnom space installed expansion tank. With it, the volume of the coolant is compensated. When heated and cooled, this parameter is constantly changing. On most cars, refilling with liquid must be done in the expansion tank. If the refueling is wrong, an air lock will appear in the VAZ-2109 cooling system. Practically on all cars the cooling system has two circuits which are switched by means of the special device - the thermostat. Also in the design include pipes, tubes of stainless materials, temperature sensors, which either include forced fan blowing, or provide data on engine operation to the electronic control unit and to an indicator located in the dashboard. From the correct operation of these sensors depends on how the engine behaves in all modes.

What happens when there is a breakdown?

The most unpleasant faults occur exclusively in the cooling system. This is a very fastidious part of the whole car. In particular, a lot of trouble is caused by air congestion. If any, the heating system works extremely ineffectively, since the radiator of the stove is practically not supplied with liquid. Also, there is excessive heating of the engine, the heat transfer is disturbed significantly. Of course, excessive heating affects the efficiency of the engine, and most importantly, its resource. In the event that there is a cork, the sensors begin to show incorrect information, since sometimes they are not in the liquid, but in the air bubble. And if there is an airlock, it must be removed immediately.

Causes of appearance

And now about why there might be an airlock in the VAZ-2114 cooling system and other cars. As a rule, air penetrates there in case there is some kind of suction from the outside. For example, poor tightening of the pipe clamps. And very much air is sucked from the outside in a cold period of time. When the temperature is very low, compression of plastic or rubber occurs, so poor tightening of the clamps leads to the formation of a cork. Very often all front-drive cars of the VAZ family break the lid, which is located on the expansion tank. It has two valves, which maintain the necessary pressure in the system. Sometimes the pump breaks down, its leak tightness is broken. There are cracks on the radiator of the stove or cooling, or there is a leak.

Serious Causes

In the event that the integrity of the gasket under the cylinder head is broken, air plugs will also appear. If the cooling system becomes clogged or if the thermostat fails, the impeller breaks on the pump also generates air in the system. Therefore, before removing, it is necessary to identify the true cause. To do this, a complete diagnosis is carried out, getting rid of blockages. Moreover, it is advisable to even flush the system, as well as replace all the elements whose service life comes to an end or has already passed. Inspect the thermostat carefully. If it has any damage or it is clogged, it is better to install a new one. And store the coolant. After all, when getting rid of the cork, its level in the expansion tank decreases. And when the air stopper is expelled in the Lada Kalina cooling system, it is necessary to make sure that all the elements are in a normal state.

How to achieve airflow?

As a rule, on front-wheel drive cars, and on all others, the air begins to accumulate exclusively in the upper part of the entire system. The highest point is the throttle, namely the branch pipe that connects to it. On cars VAZ-2114 and similar it is necessary to disconnect from a throttle knot the branch pipe. And then you can go in two ways. Either start the engine and warm it up to operating temperature, while ensuring that the coolant flows from the nozzle of the throttle assembly. But you can install instead of the plug on the expansion tank adapter for a conventional car pump. With it, pressure is created in the system, as a result of this, the liquid is squeezed out and it rises to the upper edge of the branch pipe that goes to the throttle assembly. At the moment when coolant from this nozzle starts to escape, it must be installed into place. After this, it is necessary to tighten the clamp properly. About how the airlock is chased in the VAZ-2106 cooling system and the like, will be described below.

Nuances that need to be considered

In case you warm up the engine, trying to get rid of the airlock, you need to protect yourself with long gloves, so as not to get burned from the engine components. But there is a more advanced way, only you can accomplish it together. The car must be installed so that its front part is much higher than the rear. The coolant is poured into the expansion tank to the maximum. Then it is necessary to start the engine and warm it up. From time to time, you need to squeeze the gas pedal, increasing the speed to "3500". When there is no air in the expansion tank, it is necessary to muffle the engine. This completes the pumping.

VAZ classic series

As for the classic series of cars, then there should be a different way to get rid of air congestion. It is desirable, of course, to install the car so that its front part is higher than the rear. Only this way the air lock in the VAZ-2107 cooling system will be able to go. This will maximize the radiator of the stove. Pay attention to the fact that the tap must be fully open at the same time. The liquid is poured into the expansion tank and into the radiator to the maximum level. Then the engine is started according to the principle given earlier, from time to time the rises. Only during pumping it is necessary to make sure that the liquid has gone into the branch pipe, which goes to the throttle assembly. And also, putting on a glove, push through the long branch pipes that go to the radiator. This will squeeze out the air from the engine cooling system.
