Introduction

In 1996, the production of a new family began front-wheel drive VAZ-2110. It is noteworthy that this is the only family of VAZ cars that did not receive the names, and therefore sold under the factory index (even for a foreign market, the model is simply called LADA 110). The family includes modifications in the body of a sedan (VAZ-2110, LADA 110), a wagon (VAZ-2111, LADA 111) and hatchback (five-door - VAZ-2112, LADA 112; or three-door - BA3-21123). In addition, there are various small-sector options, for example, an elongated VAZ-21108 "Premier" or VAZ-21104M - a sedan with other wings, hood, bumpers, original doors' upholsters.
The new family was distinguished by good aerodynamics, original design appearance and interior. For the manufacture of body parts that are most subjected to corrosion, galvanized metal, and fixed glasses (wind, rear and side) are glued into the body.
Even in Sedanov luggage compartment very spacious for its class, and hatchbacks and universal, in which the backs can be folded rear seatsmay also serve to transport quite overall cargo, such as a refrigerator.
Initially, only short-terrestrial carburetor 1.5-liter engines of VAZ21083 with a capacity of 69 liters were installed on the Ten. with. However, it is quite soon this power unit gave way to a new generation of engines with distributed fuel injection and electronically control. New 1.5 and 1.6 liters can have both two and four valves per cylinder, which affects their traction and cost-effective qualities.
This guide addresses currently established for all models of the family of sixteenthly smelted VAZ-2112 (1.5l) and VAZ-21124 (1.6l) with electronic control Bosch, "January" or GM, however, the above description is also fully suitable For the repair of eight-flaped engines, installed earlier.
All engines are aggregated by five-speed mechanical boxes Transmissions.
IN basic configuration The cars of the "tenth" family can boast the presence of a tweed salon, immobilizer, central locking, electric windows of the front doors and athermal glasses. More expensive equipment are equipped with heated front seats, fogy Farams, on-board computer, velor salon (which other dealers are called velvet) and cast discs. The list of equipment that can be installed on request is not limited to: a set of plastic boxes, chrome-plated door handles, a modified instrument shield, air conditioning, etc.
The "dozen" has long been possible to be called a novelty, but acceptable maintainability, as well as low prices and availability of spare parts still make this car one of the most popular among buyers. Even after in 2007, the release of the "tenth" family at the AvtoVAZ plant was discontinued, the production of models resumed in Ukraine on automotive factory Corporation "Bogdan".
Like the VAZ, Bogdan 2110 is not bad for long-distance traveling in domestic roads - good dynamic indicators are facilitated, comfortable suspension and low fuel consumption.

The factory guarantee on the tenth family cars - 35 thousand km or 2 years, depending on what will come before. Many official dealers They also give their own, more prolonged, warranty, while reducing interservice runs in one and a half or twice.
This guide provides recommendations on the repair and operation of VAZ / Bogdan 2110/2111/2112 cars with injection eight or sixteenth glove engines with a volume of 1.5 and 1.6 liters.
Note
Fuel consumption data is provided for reference and have averaged nature for various body types.
Manual recommendations can also be used to repair eight-flaped engines.

Action in Emergency Situations VAZ / Bogdan 2110/2111 / 2112. Overheating of the engine VAZ / Bogdan 2110/2111/2112

2. Overheating of the engine

As a rule, under normal operating conditions of the car, the arrow of the coolant temperature pointer is constantly in the middle zone of the scale. The temperature of the engine may increase with a long movement of the car on the rise, especially in hot weather. If the arrow of the coolant temperature pointer is in the critical zone, it is necessary to find out the cause of the engine overheating.

ATTENTION
If you continue moving by car, when the arrow of the coolant temperature pointer is in the critical zone, the engine can get serious damage and fail.

ATTENTION
Couples and splashes of boiling coolant, which are pulled under pressure from under the covers of the overheated engine, can cause strong burns. Do not raise the hood if steam goes from under it.
1. Include emergency light alarm and, squeezing the clutch pedal, send a car to the side of the road, after which it is to stay in safe place. Translate gear lever to neutral position and enable parking brake. Turn off all auxiliary electrical equipment.
2. If the arrow of the temperature pointer is in the critical zone, but steam does not go from under the hood, you should fully open the air flow control unit and install the heater to the maximum. Give the engine to work on idling within a few minutes. Watch the behavior of the arrow of the coolant temperature pointer. If overheating was caused by an increased engine load (for example, during overcoming a protracted steep rise on a hot day), the engine temperature should almost immediately begin to decrease. In this case, you need to cool the engine at idle. After normalization temperature mode The engine when the temperature pointer arrows returns to the middle zone of the scale, you can continue the trip by car.
ATTENTION
If steam does not go from under the hood, and the hot coolant does not flow on the road, do not stop the engine at once.
3. If steam comes from under the hood or if the hot coolant flows onto the road - this is a sign of depressurization of the cooling system, for example, due to the burst or jammed hose. You must turn off the engine immediately. It should be noted that the superheated engine will often not stop immediately after turning off the ignition, continuing to work as a result of the so-called pseudocal ignition. In order to forcefully stop the engine, it is necessary to smoothly squeeze the accelerator pedal stop or turning on any gear when the grip is squeezed, click on the brake and release the clutch.
4. Wait for the cessation of steam emissions or fluid leakage, and then open the hood.
5. Check the absence of visible causes of the loss of coolant, for example, cracks in the walls of hoses or leakage of pipelines. Since all engine parts and cooling systems have high temperatureYou should be careful not to get burns. If you have detected a refrigeration fluid leakage, it is necessary to eliminate the fault and restore the tightness of the cooling system before continuing the trip by car. The burst hose can be temporarily restored using adhesive tape. Damage to the radiator, thermostat or heater is quite difficult to eliminate in place, so in order to get to the nearest service station, it is recommended to add water to the cooling system and, when moving, closely monitor the temperature pointer, periodically stopping in order to make the engine cool and restore Level of fluid in the cooling system.
ATTENTION
Do not add cold water in hot EngineBecause it may cause damage to its damage. It is necessary to give the engine to completely cool when the hood is open for at least half an hour.
Do not allow the long operation of the engine using clean water instead of coolant (mixture of antifreeze and distilled water), since this will result in the formation of scale in the cooling system, as a result of which its cooling capacity will decrease, and the engine resource will decrease.
6. The cause of the engine overheating can be the resulting thermostat. To check it, it is necessary to carefully check the temperature of the upper and lower radiator hoses to the touch. If the bottom hose is cold - the thermostat is faulty, as a result of which the coolant cannot circulate through the radiator. In this case, you need to make the engine completely cool, and then continue to move to the nearest service station, carefully follow the temperature pointer and periodically stopping in order to make the engine cool.
7. If the thermostat is normal, and the engine is still not cooled, it is necessary to turn on the ignition and make sure that the radiator electric fan rotates. Check the service sensor for switching on the radiator fan. To do this, disconnect the connector from the sensor installed on the thermostat housing, and connect the connector outputs, and then turn on the ignition.
8. If the fan after closing the conclusions does not turn on, the cause of the malfunction can be a blown fuse, failed the relay or the burned motor. Check the status of the corresponding fuse (see "Fuses" section below in this chapter) and, if necessary, replace it with a new corresponding nominal value.
9. To check the performance of the fan electric motor, it is necessary to use two additional wires that need to be connected first to the electromotor connector, and then directly to the removal of the battery, observing polarity. If the electromotor earned, it is necessary to check the wiring and the switching on the radiator fan switching on using additional equipment.
ATTENTION
Wires must be isolated and securely secured. You can not allow the closures of the wires among themselves!
10. If the cooling fluid leaks were not detected, check its level in expansion tank cooling systems.
ATTENTION
Never open the plug of the expansion tank while the engine does not cool completely. Since the hot liquid at this moment is under pressure, it can spill up or from under the tube, steam under pressure will break out, which may cause serious burns.
11. If the expansion tank was empty, then the coolant topping may be required. It is necessary to wear protective gloves or cover the lid with a large piece of dense tissue. Carefully turn the cover counterclockwise to a tangible stop. Turning the lid, you should not press on it from above. After the pressure in the cooling system comes with atmospheric, you should additionally turn the cover counterclockwise. Remove the lid.
12. Police coolant. As already mentioned above, if the coolant of the recommended brand is absent, can be addressed to the radiator clean water. At the first opportunity, it is necessary to completely drain from the engine cooling system diluted with water coolant and replace it with conditioned liquid of the recommended brand.
13. Close the lid tightly. Run the engine and monitor the behavior of the coolant temperature pointer arrow. If the arrow rises again to the red zone, the engine needs repair. You should tighten the car to the service station.
14. If the temperature of the engine came to normal, it is necessary to check the coolant level in the expansion tank. If necessary, add cooling fluid into the tank and bring it to the "MAX" tag. Then close the lid of the expansion tank.

At the first signs of overheating, if the temperature pointer arrows went to the red zone, but the steam clubs do not break down from under the hood, turn on the maximum interior heating mode (see "Automatic heater control system"). This is necessary in order to reduce the temperature of the coolant in the engine cooling system.

Turn on the alarm, unlock the clutch pedal and, using the car inertia, try to gently move to the edge of the carriageway and stop as much as possible at the curb, and if possible - outside the roadway. Give the engine to work a couple of minutes at normal speed idle move with included on full power heater.

A WARNING
Do not stop immediately the engine! The only condition is to preserve the tightness of the cooling system. If I burst or jumped the hose or another leakage place was formed, except for the emission of fluid from under the plug-in tank, the engine will have to stop immediately!

After stopping the superheated engine, the local overheating of the coolant in the contact places of it with the highest engine parts and the formation of steam plugs. This phenomenon is called a "thermal blow."

1. Stop the engine.

2. Open the hood and inspect podcast space. Determine where couples come from. When inspecting the engine, pay attention to the presence of a coolant in the expansion tank, the integrity of rubber hoses, radiator, thermostat.

A WARNING
Never open at once the plug of the expansion tank. The liquid in the cooling system is under pressure, when the cork is opened, the pressure drops sharply, the liquid will boil and the splashes can be scattered. If you want to open the plug of the expansion tank on the hot engine, pre-tighten the tight thick rag from above and only after that carefully turn the cork.

Useful advice
The valve of the expansion tank stopper plays a large role in ensuring the optimal temperature mode. It supports in the system overpressure at least 0.1 MPa (1.1 kgf / cm2). At the same time, the boiling point of water rises to 120 ° C, and toxol to 130 ° C. Unfortunately, when the valve is encins, in a closed position, there is a significant excess of overpressure - more than 0.2 MPa (2 kgf / cm2), which can lead to a rupture of the expansion tank or breaking one of the hoses.

3. Take a look at the instrument panel from the front passenger side and find out whether there are leaks under it or traces of cooling fluid arising from the heater radiator.

If the leaks of the coolant are detected, the burst hose can be temporarily restored using a sticky tape.

HELPFUL ADVICE
Especially good for this purpose fits reinforced (usually silver color) sticky tape, which can be purchased in auto shops.

Leather radiator, thermostat or heater is quite difficult to eliminate in place, so in such a situation it is necessary to add water into the cooling system and when moving closely monitor the temperature pointer, periodically restoring the level in the cooling system.

Warnings
Long-term use of water instead of antifreeze leads to the formation of scale in the engine cooling system, deterioration of its cooling and, as a result, reducing the resource.
Never tighten the cold water into the superheated engine. The engine must be cooled with an open hood for at least 30 minutes.

4. The engine can overheat in case of failure of the thermostat, which adjusts the flow of fluid flow in the cooling system through the radiator or by it (to accelerate the warm engine warming). To check the thermostat, it is necessary to check the temperature of the hose connecting the thermostat body with the radiator on the heated engine. If the cold hose, the thermostat is faulty, there is no circulation through the radiator.

5. Very often the cause of the engine overheating, the cooling system is equipped with an electric fan, is the output of the fan. Let the engine, follow the temperature and pay attention to whether the cooling system fan is activated when the engine overheating.

6. If the fan does not turn on, it may have blocked the fuse, the inclusion relay is faulty, an electric motor has blocked or a wiring faulty.

7. Check the integrity of the electrical wiring, the reliability of the connection of electrical connectors.

8. If the wiring is in order, check the fuse and in case of malfunction, replace it.

9. If the fuse is good, try replacing the fan power relay.

11. If the electric motor started working, wiring faulty; If not, the wiring is also faulty or the electric motor itself. The relay and the electric motor are unrepretentious, replace them with the collection (see Section 9 "Electrical Equipment").

NOTE
It is allowed to get to the repair site with connected directly to rechargeable battery electric motor. Upon arrival, do not forget to turn off the electric motor from the battery, otherwise it will lead to its discharge.

Each car owner faced the fact that the 16-valve engine VAZ-2112 began to warm up. If you look at the indicator dashboardThe arrow strives for the red zone, and liquid boils in the expansion tank - this means that there is a malfunction in the cooling system.

The arrow of the temperature indicator went into the red zone, which means the engine in the overheating state

Many motorists remember the causes of the effect on the old "Zhiguli". On the 16-valve engines, the causes of this effect are almost the same. Consider what reasons can serve as the main power unit begins to warm the supernormum:

• System cloghood.
• Thermostat enclosure.
• Pump damage. Replace the pump. .
• Radiator.
• Fault Cooling sensor.
• Do not trigger the cooling fan (see ")".

All these problems can be caused by engine overheating.

Elimination methods

To eliminate the causes of the engine heating, it is necessary to establish the epicenter of the effect. To do this, it is worth checking out each node. After determining the problem, it is worth finding the exact cause and eliminate it. So, consider the sequence of actions.

Engine cooling system circuit

Radiator and pipes

One of the reasons for overheating of the engine may be that the radiator and nozzles are clogged, which affects the circulation of fluid in the system, and can also lead to the fact that cracks in the nozzles and the radiator breakdown will appear that the coolant leakage will appear.

With an insufficient number of coolant in the system, the power unit will warm up faster and long cool, and the cooling fan will work almost continuously.

Radiator and cooling system nozzles

The problem of solving the problem is quite simple - dismantling the radiator from the system and its cleaning both outside and inside.

The second stage will be the inspection of pipes for the expenditures and replacement of wear products. As practice shows, many motorists to extend the cooling system of the cooling system (tuning version) of the radiator and tubes.

Pomp (water pump)

One of the main causes of overheating becomes what appears platform water pump . Determine this fault is quite easy, because the corresponding howl appears in the pump area. Also, a sign of a malfunction can be the fact that with the pump shaft will flow fluid. The malfunction is eligible enough - the water pump replacement.

Water pump installed on the engine

Thermostat

Thermostat is the first place where it is worth looking for a malfunction.

So, as the thermostat in a small circle, the engine is heated more oftenEven when traveling on the highway, where a sufficiently oncoming air flow so that the system can cool.

Motor Shot Thermostat

There is one nuance when the thermostat should not be changed - this is if it failed in winter. Then, additional cooling provides a minus temperature. Of course, if the thermostat has failed in the summer, then to prevent overheating of the motor, it must be replaced as soon as possible.

Cooling sensor

The cooling temperature sensor is a harmless breakdown, which can lead to the fact that on the instrument panel, the indicator will show incorrect data, so the driver will not even know what engine overheating has occurred, until it boosts along the way.

Usually, this malfunction accompany many fair factors, so it is quite difficult to miss it. Solving the problem is one - replacement of the cooling system sensor and reset the errors that have arisen in the ECU.

Cooling sensor

Fan

The last cause of overheating, especially in the summer, the cooling system fan becomes.

The fan under the hood is indicated by the arrow

So, the breakdown of this node can lead to the fact that the engine will overheat, but.

In this case, the consequences may be the most diverse, well, you need to check the fan in good condition, as well as its inclusion sensor is accurate. This item fails quite rarely, and therefore the cause is not a triggering may become an elementary fuse or a wiring fault that is easy to eliminate.

The consequences of late elimination of defects

Not all drivers are aware of what consequences can be caused by the fact that the engine will overheat, and continue to ride with a constantly working fan or frequent overheats.

So, the consequences of strong heating of the engine are divided into 3 stages, which should be considered separately.

Weak overheating

When the engine overheating up to 10 minutes of consequences, there may be minor. So, there will be cracks in the cooling system nozzles, valve oil seals are deployed and distribution Vala.. Also, there will be extended valves, and the oil will fall into the combustion chambers, which will be marked by the release of black smoke from the exhaust system.

The consequences of weak overheating, namely the extension of the valves

Significant overheating

With significant overheating, deformation occurs, or rather deflection of the head of the cylinder block. To eliminate these consequences will have to dismantle the GBC and give it to the surface protocate. Thus, it turns out that the head of the block is subject to overhaul.

Strong overheating

With a strong overheating of the cylinder block, the cylinder block is deformed and roasted, while the piston group is melted, the deformation of the connecting rods or even the crankshaft break. Thus, the engine is not subject to repair, since it is usually walls power aggregate Rushane, and their restoration is impossible.

conclusions

Causes of heating and overheating 16 valve Engine Methods of elimination are established and considered. Thus, the late repair of this node can lead to the fact that the engine will finally fail and will be subject to replacement. Therefore, if the first signs that the cooling system gave a failure, it is necessary to find and eliminate the cause, since the replacement will be released, much more expensive.

Cooling fluid overheating alarm

Most cars are equipped with a thermal sensor measuring operating temperature Engine. If during the trip, the overheating alarm (or the temperature indicator arrow passes into the red zone of hazardous heating), it means that the cooling fluid temperature is between 120 ° C and 126 ° C. This temperature is still below the coolant boiling point (provided that the cooling system and the cooling radiator is good). If the coolant overheating signal lights up, the following must be done:

Step 1. Turn off the interior air conditioner and turn on the salon heater. This will help you quickly select the engine from the engine. Install fan on maximum speed Rotation.

Step 2. If possible, turn off the engine and give it to cool down (it may be required for more than an hour).

Step 3. In no case try to remove the hero of the radiator until the engine cools off.

Step 4. If the overheating alarm is on, it is impossible to continue the trip, otherwise the engine can get serious damage.

Step 5. If the engine does not breathe heat and is clearly not overheating, it is possible that the problem is associated with a thermal sensor fault or temperature indicator. Then you can continue to move, but it is necessary to stop from time to time to check whether the signs of engine overheating did not appear and there is no trace of the coolant leakage.

Common causes of engine overheating

Low level Coolant.

Clogged, dirty or blocked radiator.

Factable fan drive clutch or faulty electric fan.

Incorrect ignition advance angle.

Low oil level in the engine lubrication system.

Turning fan drive belt.

Faulty Her Iron Radiator.

Shining brakes.

Freezing of coolant (in frosty weather).

Faulty thermostat.

Fortified Water Pump Cooling System
(surfing the impeller on internal shaft pump).

Experience exchange

The owner complained that the engine of his car overheats, but it only happens when he rides on high speed motorway. The car was equipped with an engine, which, when driving in the city cycle, worked flawlessly.

The mechanic washed the cooling system and replaced the hermograph of the radiator and the water pump, believing that the cause of overheating was to reduce the cooling fluid consumption in the cooling system. In the course of further verification, it was revealed that when the engine was rotated, the coolant was sprinkled from one of the cylinders when the engine was twisted. The problem was eliminated after the sealing gasket of the head of the cylinder block was replaced. Obviously, the leak caused by the defect of the gasket was not so high to cause a violation of the engine mode - until the speed and load on the engine did not increase so much that the growth of the coolant leakage and heat is not caused to rapid growth Temperatures.

The mechanic also replaced the oxygen (0 2) sensor, because the composition of the coolant includes silicone compounds and silicates, which, occur to this sensor, are usually poisoned. The deterioration of the sensor characteristics could contribute to the occurrence of this fault.

Fig. 7.42. In the mid-1980s, many manufacturers began to use drive polyclinic belts (belt with longitudinal v-shaped swing instead of transverse teeth). Water pumps of old models are suitable for the engine, but it may be that they will rotate in the opposite direction to the one in which they must. This can lead to engine overheating after replacing the pump. If you install an inappropriate fan, the angle of attacking its blades will not match the required air stream through the radiator

To work properly, the cooling system is of great importance proper installation drive belt. The tension of the drive belt has a decisive effect not only to the mode of operation of the water pump, as well as the AC generator, the compressor of the air conditioning system and other belt drive units. When replacing the belt or adjusting its tension, it is necessary to measure the belt tension using the belt tension meter, in order to verify that it defines the desired.

Engine overheating is not uncommon for such a car as a VAZ 2110. mainly this problem meets with cars with big mileage. Although it is not worth excluding the overheating of the motor with relatively new instances.

The culprit is often the mileage becomes often. As the car is operating, the details wear out, the systems are gradually come into disrepair.

Common reasons

As is known, the VAZ 2110 is equipped with two types of engines - with 8 and 16 valves. There are several basic, most common causes due to which this most overheating of power units occurs.

Consider each of the reasons and ways to eliminate these problems separately.

Low coolant

The coolant plays a huge role in the cooling system. Special substance, namely antifreeze or toosol, poured into the expansion tank.

Material on the topic:

In a normal situation, the level of cooling solution must be at the level of the rapid risks of the MAX on the tank housing. This suggests that the capacity is completed by about 50-60 percent.

If there is no such mark on the tank, focus on the clamp. The fluid must reach the upper edge.

1. If the motor overheating occurs, try simply adding the missing amount of coolant so that it is at an optimal level of filling.
2. If you have not changed the coolant for a long time, it is better not to add fresh, but simply replace it completely on a new cooling fluid.
3. Choosing between Tosol and Antifreeze, most VAZ 2110 owners prefer the first. And mainly due to the financial accessibility of Tosola. But in practice antifreeze is better. Its one of the most important advantages - the substance does not freeze with severe frosts. For separate regions of our country, this is a key factor in the choice of coolant.

Thermostat

Another reason for the overheating of the motor is a jamming thermostat valve. If it remains in a closed position and does not open, the coolant will only carry out its movement on a small contour. As a result, this will lead to severe heating. power plant. Overheating itself threatens very and very serious consequences.

Such a malfunction can manifest itself at the most inopportune moment - on the way. Perform quality repairs on the side of the road you can hardly succeed. But one method can be tested - knock on the thermostat housing. Often it allows for some time to return its performance to the device. So you will be able to get to your own garage or the nearest station maintenance. There is already a thermostat is replaced with a new one. Repair it does not make sense. If he led once, the situation will certainly be repeated soon.

Material on the topic:

temperature sensor

Temperature sensor is necessary in order to react to changing the heating of the motor. When the specified mark is reached, the sensor triggers and turns on the cooling fan.

If this device malfunction, the power unit overheats, since the fan is not activated. Consequently, the temperature does not fall below the critical marks, but continues to gradually rise.

Material on the topic:

If you have a similar trouble, caught on the way ( most often, the motor overheats when it is in traffic jams, since the engine works, and there are no cooling oncoming air streams ), Try to quickly leave the congestion, find the free area of \u200b\u200bthe road.

On the free segment to turn away, and then start braking the engine. So the temperature will decrease, the overheating will not happen. It is impossible to regularly exploit the car in any way. But this is a great way to get to the garage or car service, determine the cause of the sensor fault, and then replace it.

Cooling Fan

The symptoms of fan faults is similar to the non-operating temperature sensor. That is, the engine will warm up, the pointer on the dashboard will be in the red zone.
