Why does the heating of the VAZ 2114 badly? Troubleshooting tips
Optimal temperature in the cabin - a depositcomfortable ride. In summer, this function is performed by climate control and air conditioning, and in the winter time - the stove. However, what should I do if the VAZ 2114 does not heat the stove on the car? Causes at low engine speeds can be very diverse. So, let's look at her device and malfunctions.
Device and purpose
This node performs the function of redistributionair in the cooling system. The principle of its operation is quite simple - the stove takes away 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 flaps controlling the speed and direction of the air supply.
- Electric fan.
A good node should provideunhindered air circulation in all the above elements. But what to do if it does not heat 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 parsestove. Preliminary it is necessary to start the car and to include system on the maximum level of work. 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 car VAZ2114 badly heats the stove (on idle ones, including), is the breakage 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 little. Check the serviceability of the thermostat is quite simple. When dismantling it, 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, the item should be replaced with a new one.
Fortunately, it is inexpensive. By the way, experienced motorists recommend changing thermostats depending on the operating season. For example, in 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 VAZ 2114 stove does not heat well, you can check the part indiscriminately - for this, on the warmed-up 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 is that the system is airborne. The plug can be formed after the engine is switched 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 coolant, which will cause the motor to overheat and the badly functioning stove. How to get rid of this jam? For this, 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 that was 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 should be as transparent as possible (the factory color does not count), the touch feels slightly oily. If it has not changed for a long time and has lost these properties, it has become cloudy, then it is better to merge it completely and use a new "unfrozen". If the stove does not heat well (VAZ 2114 1.5 including), you can get rid of the airlock in another way - just drive the front of the car up and open the lid 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 stove 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 - 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, since the old ones will be 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.
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.
water pump
It happens that the stove stops functioningbecause 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 may 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 defective stove isburnt gasket cylinder block. 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".
Motor stove
This item can also fail. Check its serviceability is quite simple. 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 wonder why it does not heat wellstove on VAZ 2114 ", it is necessary to make 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.
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).
