Why the "Kalina" does not heat the stove: the reasons, how to fix the problem

Often, car owners think about the serviceability of the stove only at the beginning of winter. But sometimes it can fail. Not exception is the "Kalina". On it, as well as on many other cars of the Volga manufacture, the stove breaks. What are the reasons for this, and how to eliminate this problem? About all this - later in our article.

Coolant

As you know, the salon heater has its own radiator. It is filled with coolant. This design is part of the basic cooling system. If the "Lada Kalina" is not warmed by the stove, the reasons may be a low level of antifreeze. Open the hood and look at its level in the surge tank. It must be between the minimum and maximum mark. Also, a bad heat sink can be due to the presence of an airlock. How to test it? On the cooled motor, touch the upper and lower radiator hoses. They should not bubble when squeezed. If this is the case, then the air is formed in the system. He could go there for various reasons. But in any case, you need to get rid of it. How to do it? It is necessary to drive the front of the car to an elevation and open the cover of the expansion tank. Then start the engine and let it run on idle (with periodic sub-calls to two or three thousand) a couple of minutes. After that, you can move out of the slope and close the lid.

Thermostat

This is another reason why the stove does not heat well on Kalina. The problem is that the stream of antifreeze on the salon heater is sent only after warming up the coolant on a small circle. The thermostat is a kind of valve that controls the flow of fluid in the system. As soon as the temperature of the antifreeze in the small circle exceeds 72 degrees (or 82, depending on the brand), it opens and circulates along a large circle. If the Lada Kalina does not heat the stove, check the thermostat. This can be done in two ways:

• With dismantling. In this case, the element is extracted from the car (the tosol is firstly drained into a clean container). Then it is placed in a small pot filled with water, and heated on a plate. At this time, follow the movement of the valve. If the water starts to bubble, and the thermostat has not yet opened, then it has become worthless. The element can simply jam. It happens not often, but it is because of this detail that the machine suffers overheating and problems with the salon heater.
• On the spot. In this situation, the motor should warm up to operating temperatures. Next, you need to find the top and bottom of the radiator pipe. Gloves should be touched in turn to each of them. If the branch pipe is cold on a warm engine, then the antifreeze circulates only through a small circle. The thermostat can not be repaired or changed entirely. Fortunately, its cost is small - about 200 rubles.

Radiator

In any car there is this element. In addition to the main one, a radiator is installed. He is slightly smaller, but it is on his condition that the efficiency of the stove depends. So, this element can simply be hammered. And both outside and inside. Most often contaminated by his insides. This is due to the ignoring of the coolant replacement regulations. Recall that the antifreeze changes every 2 years or 60 thousand kilometers, and antifreeze - every 5 years or 150 thousand. If the liquid does not change in time, it will lose its properties. Additives will cease to function, and corrosion forms in the system. In the liquid itself there will be characteristic flakes. They also clog the small channels of the cooling system and heat exchangers.

The element can get dirty from outside. So, often honeycombs suffer from down and dry foliage. The way out of the situation is external cleaning of the element. It is carried out on the removed radiator.

Sensor

If the heater does not heat on the "Kalina", the reasons can be in it. The fact is that on the "Kalinas" in the ceiling (near the lighting plafond) is installed a sensor that senses the temperature of the cabin. It can affect the operation of the heater. The electronics compare the obtained data on the heating of air with those that the driver exhibited, and thus adjusts the position of the dampers. Over time, the contacts on this sensor can be oxidized. The system stops working as expected. From the nozzles, either cold or hot air is blowing (and, regardless of the parameters set). If the "Kalina" does not heat the stove, the problem is solved by cleaning the contacts, or by replacing the sensor itself.

Cabin Air Filter

In addition to air, in Kalina there is a salon filter. He is responsible for cleaning the air coming into the cabin. The element should change every 10 thousand kilometers (under extreme conditions - every 5 km). If the "Kalina" does not heat the stove, the reason may be in it. In this case, the intensity of the flow itself will drop substantially. From the nozzles, the air will be weakly blown. The way out is to install a new salon filter. It costs about 300 rubles. To replace, you need to open the hood and remove a part of the "jabot" under the windshield wipers. Next, open the lid and remove the contaminated element.

In its place, install a new one and close it with a plastic lid. It should be noted that in the sale there are both conventional, paper and carbon filters. The latter in addition to dust and detain bad smells. As the reviews say, this filter is much more efficient than the standard one. And it does not get dirty sooner than usual. Outwardly it can be distinguished by color. It is slightly darker (graphite tint predominates).

Motor stove

This is another reason why the Lada Kalina does not heat the stove. But if in previous cases, when the heater was switched on, a distinct sound of the fan was heard, then it will be absent here. First of all, check the safety of the fuse in the unit. On the "Kalina" for the work of the stove motor meets the element F5. Sometimes the mechanism can work, but with strange sounds or intermittent. In this case, the element must be replaced. To remove it, you will have to partially disassemble the front right side of the car. The motor is located just behind the salon filter. A new fan from the company "Luzar" will cost about one and a half thousand rubles. This is perhaps the most expensive element after the radiator in the stove.

So, we found out the malfunction of the stove on "Kalina" and how to fix this problem.
