Why does the heating of the VAZ 2114 badly? Troubleshooting tips

The optimum temperature in the cabin is the guarantee of a comfortable ride. In summer, this function is performed by climate control and air conditioning, and in winter - the stove. However, what to do if the car VAZ 2114 does not heat the stove? Causes at low engine speeds can be very diverse. So, let's look at her device and malfunctions.

Device and purpose

This unit performs the function of air redistribution in the cooling system. The principle of its operation is quite simple - the stove takes some of the heat from the motor and sends it to the salon. So the heat inside the car is maintained. This node consists of several elements:

• Branch pipes.
• Radiator of the stove.
• Crane adjustment level of the circulation of antifreeze.
• Air ducts and dampers controlling the speed and direction of air supply.
• Electric fan.

A functioning node should ensure unobstructed air circulation in all the above elements. But what should I do if I do not warm the VAZ 2114 (injector, 8 valves)? The reasons can be different. Let's consider each of them.

The electric fan is not working properly

In this case it is necessary to analyze the stove. Preliminary, start the car and turn on the system to the maximum level of operation. In the absence of noise, the fault of the fault is the electric fan. Experienced motorists recommend changing it to a mechanical one. It is believed that he is more reliable in this regard.

Thermostat

In addition, the reason that the VAZ 2114 badly heats the stove (on idle ones), is the failure of the thermostat, namely, the opening of the valve. Thus, the circulation of the cooling liquid is carried out only over a small circle. The machine with such a malfunction often boils, and in the winter - the stove does not work, or it heats very slightly. Check the serviceability of the thermostat is quite simple. When dismantling it, you should place the part in a container of water and heat it on the komorka. Before the boil in the water (bubbles will form), the valve should open. If this does not happen, replace the item with a new one.

Fortunately, it is inexpensive. By the way, experienced motorists recommend changing thermostats depending on the operating season. For example, in the summer it is better to put the element at 82 degrees, and in winter - at 72. It is not necessary to adhere to specific values, just remember the principle - the colder in the street, the lower the valve opening temperature should be. If the furnace VAZ 2114 does not heat well, you can check the part indiscriminately - for this, on the warm engine, you need to touch the upper and lower branch pipes of the main radiator. Both elements must be hot. If one of them is cold, most likely the valve has not opened, and the thermostat must be replaced.

Airlock

If the car VAZ 2114 badly warms the stove, the reason for this - zavozdushivanie system. The plug can be formed after the engine is turned off, when the temperature of the antifreeze will fall. It is at this time in the radiator part of the expansion tank can get air, which then "stuck" around the thermostat. At the next start-up, the system will circulate the air instead of the cooling fluid, which will cause the motor to overheat and the badly functioning stove. How to get rid of this jam? For this, the motorists loosen the OC nozzle clamp and slowly add the tosol to the expansion tank to the maximum. By the way, mixing different brands of coolant is impossible - the system can foam. Therefore, we add only the brand used earlier, or we use distilled water. The latter method is used in any season, with the exception of the winter one, since water at a negative temperature will simply freeze in the tank. The antifreeze must be as transparent as possible (factory color does not count), it feels slightly oily to the touch. If it has not changed for a long time and has lost these properties, it has become turbid, then it is better to merge it completely and use a new "unfrozen". If the heater does not heat well (VAZ 2114 1.5 including), you can get rid of the airlock in another way - just drive the front part of the car up and open the cover of the expansion tank. Waiting 3-5 minutes, the system itself will push out all unnecessary air.

Crane failure

This detail, too, should not be ignored by attention. If the heater does not heat well (VAZ 2114 injector 8 valves), the reason can be hidden in it. In most cases, it does not fully open. The reason is poor fixation of the rope rope. On cars "Samara-2" it is located near the pedals. To resume the work of the node, it is necessary to tighten the element with the help of pliers.

It happens that the heater does not warm the VAZ 2114, the damper is open, and the salt is dripping into the saloon. The cause of the malfunction lies in the depressurization of the seals (most often on the tap). If there are clamp connections, they should be tightened. Also, we carefully look at the condition of the nozzles themselves. They should be soft, without cracks and other signs of wear. Otherwise, you need to purchase a repair kit and completely change the nozzles (it's best to purchase new collars, too, since the old ones are sour).

The radiator is clogged

In its honeycombs can accumulate debris and dirt, because of what the flow of warm air into the cabin comes very weakly. The way out is to flush the element with citric acid or anti-scum agents.

Breakdown in the radiator

If the honeycombs are damaged, the circulation of the antifreeze will deteriorate significantly. In this case, only a replacement. And you need to change strictly to a new one. Never buy a used radiator. In order to replace it, you need to disassemble the console and the front panel of the car. Next, prepare a clean container with a volume of 5 liters or more and drain all the antifreeze from the system through the tap on the radiator. Then remove all fixing nuts and radiator fixing bolts. The location of the latter is indicated on the photo by an arrow.

After installing a new element, do not forget to add the antifreeze to the system again. To avoid air jams, do not pour large amounts of liquid into the surge tank. Pour 200 ml - wait 10-15 seconds, then add more. And so on until the system is completely filled with antifreeze.

water pump

It happens that the stove stops functioning because of low pressure in the system. The water pump is responsible for this function. Symptoms - when the car moves the heat does not enter the interior. The solution to this situation is to replace the water pump. Motorists recommend choosing a duralumin component - it is much more reliable than the regular one.

The level of antifreeze

Why does the heater on the VAZ 2114 badly heat? The reason can be banal - a low level of antifreeze in the heating system. In winter, it should be slightly more than the maximum mark (by 1-2 centimeters). As we said earlier, it is impossible to mix different brands, and to avoid air congestion - pour in small doses, with small interruptions.

Cylinder head gasket

Sometimes the cause of the faulty stove is the burnt cylinder block gasket. This malfunction can be determined on several grounds. First, it is the presence of a smell of gasoline or exhaust gases in the antifreeze. Secondly, on the dipstick and the lid of the oil filler neck there is a certain mixture - "mayonnaise". It occurs due to the mixing of car oil with the cooling liquid. Also, from the exhaust pipe, when the engine is running, characteristic white smoke will be seen. If you have at least one of the above signs, you should diagnose the condition of the gasket and replace it immediately.

Motor stove

This item can also fail. It is quite easy to check its serviceability. To do this, turn the regulator responsible for the temperature regime. If nothing has changed (the air as it was cold, so it remained), it is necessary to replace the motor of the stove. After that, the problem with its functionality disappears.

Prevention of malfunctions

In order not to ask the question "why the heater does not heat the VAZ 2114 badly", it is necessary to perform regular preventive maintenance of the unit. It consists in the periodic analysis of the system and cleaning of its every detail. Change the antifreeze often. Fresh antifreeze will go unhindered through the thermostat valve to a large circle, including the stove. Also, check the tightness of the faucet and the nozzles that fit the radiator. If they have cracks, they should be replaced. On a well warmed-up engine, the presence of streaks is unacceptable. For better tightness, motorists advise using a "fum-tape", winding it on technological connections. On top of her dress nipples and fixed clamps. Every 2 years, flush the cooling system completely .

Conclusion

Observing these rules, you not only prevent the failure of the stove, but prolong the life of the motor. After all, each of us knows that the heat and the engine are incompatible concepts. At the slightest overheat it leads the head of the unit. And its repair is much more costly than the new can of tosola.

So, we found out why the VAZ 2114 stove does not heat well. As you can see, the problem can be solved by oneself with minimal investments (if you notice the malfunction in time).
