VAZ 2114 injector cooling fan does not turn off, causes of malfunction

VAZ 2114 is a restyled model of the well-known “ten” or “Samara”. This car became widely known, so this brand of five-door hatchback can be found on the roads today, despite the fact that this car was removed from the production line several years ago.

This car has an electronic engine control system. Many people know that an injector of this type often begins to behave unpredictably. This usually happens when going to idle. As a result, the revs “float”, and the car owner cannot understand what happened to his beloved vehicle.

It is very difficult to immediately determine why the VAZ 2114 injector stalls at idle. As a rule, this requires diagnostic measures, which are best performed at a service center. However, you can try to understand on your own why the car stopped working as it should. Therefore, it is worth listening to the opinions of professionals who have encountered such malfunctions.

Fan device on VAZ-2114

4-blade radiator cooling fan

Before moving directly to the causes and methods of solving the problem, it is necessary to understand the design features of the unit. In other words, how does a radiator fan on a car work?

Cooling system fan design

Radiator and electric fan parts: 1 – radiator; 2 – radiator cap; 3 – electric motor; 4 – casing; 5 – impeller; 6 – rubber cushion; 7 – drain plug

It is also worth considering the electrical circuit of the radiator fan:

The fan does not turn off: the main causes of the malfunction

Now that we know how the fan radiator works, we can move directly to the issue of identifying the reasons for its failure. So, let's look at what causes the node to not turn on:

• Wiring shorted.
• Relay.
• Temperature sensor (see “Replacing the coolant temperature sensor (DTOZH)“.
• ECU.

Elimination methods

After the motorist has identified all possible causes, it is necessary to move directly to elimination methods. It is worth warning that this malfunction is associated, for the most part, with electrical circuits , where certain knowledge is required, therefore, if the motorist is not confident in his abilities, he should contact a car service center.

• Why the radiator fan on the VAZ-2114 does not turn off: signs, causes and solutions

So, let's consider the sequence of actions aimed at eliminating the problem.

Wiring short circuit

Fusion of two wires

Often, the effect of the cooling fan not turning off is the fusion of the contact group wires.

Simply put, the contacts simply close due to the fact that the wiring insulation has melted. This effect could be observed on old Zhiguli cars when they forced the fan to rotate.

The solution is to replace part of the wires, which even a novice motorist can handle. You can replace the entire wiring harness or simply replace the burnt part of the wire and insulate it with electrical tape.

Fan relay

Mounting block where fuses and relays are located. But the fan relay is located in a separate relay in the cabin. Location of the additional relay block in the vehicle interior Fan switch relay in the additional mounting block

Another problem may be the failure of the electric fan control relay, or rather its short circuit within itself . In this case, it must be removed from the mounting block and a new one installed. If the malfunction disappears, then the problem was in the relay.

Coolant temperature sensor

Original view of the coolant sensor produced by AvtoVAZ

Failure or improper operation of the coolant temperature sensor causes the fan to not turn off. If the sensor freezes, the electric fan does not work , and the ECU thinks that the engine temperature is the same as on the sensor. There will be more critical consequences if the instrument panel does not show the engine temperature.

The solution to the situation is to replace the damaged element.

ECU

Electronic engine control unit

• VAZ 2112 cooling fan does not work

Not often, but the problem becomes that there are errors in the electronic control unit, especially in terms of cooling, the electric fan does not turn off. So, the method of eliminating the problem is resetting all errors or completely flashing the ECU. It is best to entrust this process to professionals and send the car to a car service center.

conclusions

The radiator fan on the VAZ-2114 is used to forcibly cool the engine and cooling system when natural cooling is insufficient. It turns off especially often if the temperature sensor is broken.

Its failure can lead to unexpected consequences, therefore, it is necessary to determine the cause of the malfunction in a timely manner and eliminate it . If the motorist is unable to do this, then it is worth contacting a car service center.

The engine cooling fan should operate when the antifreeze reaches a temperature of 101 degrees. If the fan electric motor turns on and starts working even when the engine is not warmed up, the driver will need to solve this problem.

Signs of fuel pump failure and the main causes of failure

The fuel pump becomes the main suspect for failure in situations where the car suddenly stalls while driving. In this case, it can start again from the starter, but it begins to make unusual sounds. When parked, the VAZ 2114 may start starting every once in a while.

Similar engine behavior can also occur for other reasons. Therefore, indirect signs must be monitored. These include

• lack of standard pressure in the fuel supply system;
• the engine begins to twitch noticeably due to improper supply of gasoline to the cylinders;
• the engine begins to “growl” at low speeds (however, this symptom is identical to both the onset of pump failure and can be caused by a heavily contaminated fine fuel filter).

Most often, in a VAZ 2114 fuel pump, the fuse, relay, electric motor, and contact system fail.

How to solve a problem

1. First, you need to check the integrity of the insulation of the wires going to the coolant temperature sensor (DTOZH), which is located in the cylinder head, on its inlet pipe. If, for some reason, they begin to short to ground, then the fan must turn on, since this false signal tells the controller that the temperature of the antifreeze in the engine cooling system has risen to 130 degrees. Since the controller does not know that this signal is false, he naturally turns on the fan.
2. The second reason for the constantly running fan of the VAZ-2114 may be associated with a “glitch” of the controller, which turns it on based on the control signal of the coolant sensor, and after the antifreeze temperature drops as a result of the fan operation, does not want to turn it off. This may be due to the controller firmware.
3. The voltage to the terminals of the electric motor of the engine cooling system fan is supplied through the contacts of the relay, which is located in the additional relay and fuse box located in the front passenger's feet behind the side cover covering the front console. If the contacts of this relay are stuck, the fan will turn on and work immediately after turning the key in the ignition.
4. If the fan does not turn on immediately, but only after the engine has warmed up and then does not turn off, then the reason for its operation may be due to a low level of antifreeze in the engine cooling system or a malfunction of the thermostat, which refuses to open its valve to ensure fluid circulation in a large circle ( through the radiator). It's quite easy to check. Open the hood and check the coolant level on a cold engine. If it is normal, start the engine, let it warm up to operating temperature and feel the radiator supply hose with your hand.

Idle speed control

On VAZ models with an engine of 8 or 16 valves and on foreign cars, the power unit starts up, then stalls due to IAC. The wrong name is idle speed sensor, the correct name is regulator.

The device monitors engine speed and maintains it. At idle, the engine stops working, or uneven speed is observed - the part is faulty. When the gearbox is switched to neutral, the engine stalls - it is worth changing the regulator.

Sometimes similar symptoms are observed when the throttle valve is dirty. It is recommended to clean it first.

Wiring short circuit

One of the common reasons why the cooling fan on a VAZ 2114 constantly works is a short circuit in the wiring. To identify this malfunction, you will need to use a multimeter to test all the wires that lead to this part. Often damaged wiring can be seen by eye. Upon inspection, melted or fused parts may be visible.

Reasons for "blondes"

Sometimes poor performance of the injection system is simply due to inattention to the condition of the car and untimely maintenance. 1

Filters are clogged. Replacing air and fuel filters is a mandatory part of car maintenance for experienced car owners. The average service life of filters on a VAZ is 30,000 km. The actual value depends on the quality of the fuel and the filter itself, and operating conditions. If the car has traveled more than 100 thousand kilometers, it is advisable to change the filters more often, every 10-15 thousand (or once a year). During this mileage, dirt inevitably accumulates in the system.

1. Filters are clogged. Replacing air and fuel filters is a mandatory part of car maintenance for experienced car owners. The average service life of filters on a VAZ is 30,000 km. The actual value depends on the quality of the fuel and the filter itself, and operating conditions. If the car has traveled more than 100 thousand kilometers, it is advisable to change the filters more often, every 10-15 thousand (or once a year). During this mileage, dirt inevitably accumulates in the system.

If your car stalls in neutral or immediately after starting the engine, start by inspecting the filters.

2. Lack of gasoline. The critical fuel level cannot be allowed. Dirt may get into the fuel line and settle at the bottom of the tank. If the gauge has reached a critical level (or does not work), the car has just been driving, and after stopping it does not start or starts and stalls, you may need to add fuel.

Firstly, the accuracy of the FLS on the VAZ is not ideal. Secondly, if you stop at a slight level on a slope, fuel may not be sucked in by the pump at all or may be mixed with air.

3. Crooked hands. If the problem appears immediately after repairing the machine, carefully check the connections of all chips or the integrity of the wires. The reasons why the engine stalls may lie there.

Relay

Often the cooling fan does not turn off due to a failed fan relay. It is installed in an additional mounting block “four”. This block is located near the front passenger's feet and is covered with a decorative trim.

It is not necessary to use a tester to detect its breakdown. It is enough to take a similar element from the owner of the same car for a couple of minutes and replace it with your own. If the fan operates normally, the relay has failed and needs to be replaced. It is inexpensive, and you can replace it yourself.

DTOZH

The radiator fan of the VAZ 2114 may not turn off due to a malfunction of the coolant temperature sensor. This device transmits information about the antifreeze temperature to the ECU. If it exceeds 101 degrees, the fan turns on to cool it down. If the DTOZh breaks down, the electronics receive an incorrect signal. Therefore, the element can operate continuously. The sensor is installed in the cylinder head on the intake manifold.

It is not necessary to call the DTOZH to check. You can borrow a known-good part for a while and evaluate the operation of the system. If everything works as expected, the sensor should be replaced. Sometimes damage to an element can be noticed visually.

When checking this part, it would be useful to inspect the wires and their connections. Sometimes the cause of the malfunction lies in poor contact or broken wiring. In this case, the connections are cleaned of contaminants and the integrity of the wires is restored.

Fuel pump design

The fuel pump is located directly in the fuel tank and is driven electrically. Power to the electric motor is supplied from the on-board network of the VAZ 2114. The key component of the pump is a membrane, which, when the electric motor is running, performs reciprocating movements.

The unit is constantly flushed with fuel even at its minimum level in the tank. This design of this part of the fuel system is necessary because a running electric motor gets very hot, and gasoline takes on the additional function of a coolant.

ECU

If the diagnosis of all other elements did not help, then the cause of the breakdown is a malfunction of the electronic control unit. But this doesn't happen often. It is not always possible to determine this malfunction on your own. Therefore, if an independent check does not give positive results, you should contact a car service center.

If the ECU fails, it is flashed to remove all existing errors or the unit is replaced. These procedures should be performed by an auto electrician. It is not advisable to do such work without experience. This device is not cheap, but, fortunately, it is replaced quite rarely. There are also several other very rare reasons why the cooling fan may not turn off. Unlike the malfunctions described above, they can usually only be identified and eliminated at a service station.

Air filter

If all the reasons described above do not apply, then you should pay attention to the filtration system. This unit also often leads to malfunctions

On injection-type cars, filters are adjusted to an optimal and universal operating mode. This element is necessary in order to trap dust and dirt, but not impede the passage of clean air. Typically, small panel filters are installed in VAZs. They are considered more efficient and compact. However, cylindrical models are often installed in cars, which quite quickly cease to perform the task correctly. In this case, you will need a simple diagnosis of the VAZ 2114 car and replacement of the damaged element.

Reset errors

Sometimes after repairs have been carried out, error codes still remain in the memory of the electronic control unit. They may interfere with the normal operation of the fan and may also be displayed on the on-board computer. In order to restore the functionality of the element, you need to remove them. This can be done in two ways.

1 way. To do this, you will need an OBD scanner and a laptop or smartphone with the appropriate application. Errors are reset in the following sequence:

1. Connect the scanner to the diagnostic connector of the car and a laptop or other gadget.
2. Turn on the ignition.
3. In the program, press the READ key and press ERASE. Sometimes you need to select YES or CLEAR to clear errors in an application.

Method 2. If you don’t have a diagnostic scanner, you can use another error removal algorithm:

1. Turn on the ignition without starting the engine.
2. Open the hood and loosen the negative terminal of the battery.
3. Wait approximately 1 minute.
4. Place the terminal in place, securing it securely.
5. Close the hood and turn off the ignition.

After clearing the fault codes, you need to turn on the ignition and check for errors. You also need to make sure that the fan is functioning properly. If resetting does not solve the problem, the problem may have been identified incorrectly.

You can drive with a constantly running fan, but provided that the antifreeze temperature is normal. If it is high, then you need to stop and not use the machine until the problems with the cooling system are eliminated.

On a VAZ model 2114, the injector cooling system uses an electric fan, which is turned on by a signal from the temperature sensor.

The main malfunction is that this unit fails, which requires replacement of the fan and other components that control its operation.

Eliminating camshaft knock on an 8 valve engine

Before starting work, you need to remove the engine valve cover, remove the cover of the right support cushion and pull out the valve tappets. This will free up access to the camshaft and, if necessary, allow it to be rotated to determine the play, since the shaft is completely unloaded.

When the camshaft of a VAZ-2114 or another model from this series knocks, two types of play are observed - longitudinal and transverse, and each of them has its own method of elimination.

Elimination of longitudinal play

With longitudinal or axial play, a gap appears between the rear support cover and the camshaft flange. To eliminate this gap, you need to select a sealing washer. For this purpose, galvanization with a thickness of 0.5 mm is suitable, from which a washer with an internal diameter of 25 mm and an external diameter of 35 mm is cut.

Experience shows that this is enough to eliminate the camshaft axial play. Another option is a boot from bearing 302, which is installed on the car’s generator, so it’s better not to throw them away when replacing them. After removing the boot, you need to burn it to get rid of the rubber shell. The result is a metal washer that is ideal in size.

After this, remove the rear support cover, for which you need to unscrew 2 nuts and one bolt with a 10mm wrench. The washer is installed and the cover is put back in place. It is important that after tightening the shaft rotates freely; the force may increase slightly due to the elimination of backlash, but not critically. If the camshaft is tightly clamped and rotates with great effort or does not rotate at all, you need to remove the cover again and grind the washer. It happens that installing one washer does not remove the backlash; in this case, you need to install one or two more washers.

How to identify a malfunction

You can determine if there is a malfunction in the cooling system fan by increasing the coolant temperature. Also, a corresponding indicator indicating an increase in coolant temperature appears on the car’s dashboard. The car owner should turn off the engine and wait until it cools down, then carefully continue driving.

The malfunction can be determined by visual inspection of the radiator and fan. If, with a significant increase in coolant temperature, the fan does not turn on, this indicates the presence of various breakdowns of this unit.

Causes of fan malfunction:

• Temperature sensor failure.
• Lost contact at the temperature sensor connector.
• Broken electrical wiring.
• Relay problems.
• The fuse has blown.
• Fan motor drive malfunction.

Necessary tool

The choice of tool used will directly depend on the nature of the breakdown. Often it is enough to open the relay box and replace the blown fuse with a new one, which will restore the fan’s functionality. Whereas in case of significant breakdowns, when the cooling fans of the VAZ 2114 do not turn on, it is necessary to dismantle the radiator, remove the fan, or change the relay and corresponding temperature sensors. To remove the fan you will need:

• Crosshead screwdriver.
• Socket wrenches 8 and 10

Step by step repair

1. Initially, it is necessary to carry out appropriate diagnostics, this will allow us to determine the reason why the radiator cooling fan does not turn on in a timely manner, which will simplify subsequent repairs;
2. It is recommended to disconnect the fan connector, and then, observing the polarity, reconnect the connector directly to the battery terminal. If, with such a direct connection, the fan begins to rotate, this indicates a working drive; the reason in this case may be electrical wiring, a faulty temperature sensor, or problems with the fuse.
3. You can check the fuse responsible for the operation of the cooling fan without opening the plastic box. The fact is that such a relay is dual and is simultaneously responsible for the operation of the horn. Therefore, if the car's sound signal disappears and the fan does not work at the same time, this indicates a blown fuse. The block with such relays is located under the hood in a small plastic box. To open it, you need to remove two latches, then use tweezers to remove and change the fuse you need.
4. Relay failures are difficult to diagnose. We recommend getting a 100% working relay, temporarily installing it in the socket and checking that the fan is turned on correctly. If during such a check the fan starts working, then the relay used should be replaced with a working one.
5. To check the temperature sensor, from which the signal goes directly to the radiator, disconnect the connector from the sensor and then turn on the ignition. At the same time, the automation starts the fan for constant blowing in emergency mode. If, when the connector from the sensor is disconnected in this way, the fan turns on late, then we can therefore conclude that the temperature sensor has failed and will require replacement. The temperature sensor itself is fixed with two bolts, which can be unscrewed with a simple Phillips screwdriver. This sensor replacement usually takes no more than 5 minutes.
6. If the cause of the breakdown is still the fan, you can try to repair it first or immediately replace it with a new one. The problem may be with the bearing or brushes. In this case, you can replace such damaged parts, which will completely restore the functionality of the cooling system fan. If the cause of the fan breakdown is the electric motor, then the repair presents certain difficulties, and such a failed drive is best replaced with a new one.

In order to remove the fan with the drive you must:

1. The VAZ 2114 car is placed on a level surface and the parking brake is applied.
2. Open the hood and disconnect the negative terminal.
3. The air filter housing should be unscrewed with a ten key.
4. Loosen the clamps at the air duct.
5. We twist the screws that secure the air filter and remove the filter element.
6. Next, unscrew and dismantle the air intake, which will require an eight key.
7. Remove the fan casing by unscrewing 6 nuts with the eighth key.
8. Remove the motor block.
9. Remove the fan with the drive.

Next, you need to install the new drive or the entire fan assembly in place and carry out the assembly in reverse order. After such repairs, you should check the correct functioning of the fan, for which we warm up the engine and wait for the blower to turn on.

ADJUSTMENT

In any case, if a characteristic valve knock occurs in the engine, it is necessary to check the condition of the valves. In this case, adjustments should be made. To adjust the valves of the VAZ 2114, factory-made adjusting washers with a thickness of 3 to 4.5 millimeters are provided, the thickness changes every 0.05 mm. We make the adjustment as follows (you will need a special shim remover and washers themselves of varying thickness):

• Disconnect the throttle cable bracket from the valve cover;
• Remove the valve cover (two bolts);
• We dismantle the timing belt casing;
• We set the top dead center in the first cylinder of the internal combustion engine (there is a mark on the timing gear). How to align the marks can be found in the repair and operation manual. You can turn the camshaft clockwise using the camshaft bolt. But this must be done carefully and without unnecessary effort;
• We check the gap with a set of automotive feeler gauges between the pusher and camshaft cams 1 and 3 valves according to the timing belt. The intake valve should have clearance

0.2 mm, at graduation it is larger on average

0.35 mm;

• We remove the adjusting washer and look at the markings (thickness is indicated in three numbers). Using mathematical calculations, we determine the required thickness to adjust the gap and install the new washer in place. We immediately check the resulting gap;
• We turn the camshaft a quarter turn clockwise and adjust valves 2 and 5. After another quarter - 6 and 8, the last ones to adjust are valves 4 and 7, also after ¼ turn.
• After adjustment, we put everything back together in the reverse order, start and listen to the engine.

Conclusion

There may be many reasons why the cooling fan on a VAZ 2114 does not turn on. We recommend that the 2114 car owner carry out appropriate diagnostics, determine the cause of the breakdown and fix it independently or completely replace the cooling fan.

Content

Sometimes car enthusiasts are faced with the fact that the cooling fan on a VAZ 2114 is constantly running. The reasons for this phenomenon can be very different, and in order to eliminate the malfunction, you should clearly understand what could have led to it. We’ll talk about why the fan stops turning off and how to fix it in today’s article.

Cooling fan VAZ 2114

Self-diagnosis of ICC

To understand that this particular unit is the cause of a stalled engine, it is enough to pay attention to several signs:

1. The car's power unit stops working as soon as one of the gears is turned off.
2. The revolutions begin to “float”.
3. When XX is activated, the motor begins to malfunction.
4. As soon as the car owner starts the engine when it is cold, it becomes impossible to increase the speed.
5. When the driver turns on the headlights or other light optics, the engine speed begins to drop noticeably.

Design and principle of operation of the fan

Before you move on to repairing the fan, you should understand the principle of its installation on the cooling system. To do this, it is better to use the following simple diagram, on which the following main parts are indicated by numbers:

1. — cooling radiator.
2. - cork.
3. - electric fan motor.
4. - protective casing.
5. - fan impeller.
6. — damper pillows.
7. - coolant drain plug.

In addition, a diagram of the electrical equipment of the cooling system, which looks like this, will also be very helpful in repairs:

As you can see, the start of the cooling fan is controlled by a relay, which starts after receiving a signal from the temperature sensor.

Once the liquid in the radiator reaches a certain temperature, the temperature sensor closes and thus triggers the fan to start.

Once the temperature of the liquid in the radiator drops below a certain point, the sensor will open and the fan will automatically turn off. But, as already mentioned, sometimes this does not always happen.

Let's consider them in order.

Closure

The first and most common reason for such a malfunction is a short circuit (and most often, fusion) of the wires going to the fan. As a result of this short circuit, the electrical circuit turns on, regardless of the operation of the temperature sensor and relay. It is very simple to identify such a malfunction - just ring all the wires and check whether they are shorted (in some cases, the fact of fusion of wires can be detected even visually during inspection).

Fusion of two wires

If the “diagnosis” does not produce results, then the search for the cause should be continued, namely, checking the fan relay. The easiest way to do this is to dismantle the relay and install a new one of a similar model in its place.

Although the price of this device is low, you can do without purchasing a new relay at all. It’s enough just to borrow it for a couple of hours from a motorist friend who owns a VAZ 2114, and after checking it, return it back.

If after replacement the fan begins to operate normally, it means that the old relay was indeed damaged, and you will still have to buy and install a new one. If not, then you should move on to checking the temperature sensor.

Thermal sensor

Thermal sensor (also known as coolant temperature sensor, also known as DTOZH) is a device that reports the coolant temperature to the electronic system. As already mentioned, it is this that causes the fan to start and turn off depending on the temperature of the radiator. It is not surprising that a broken temperature sensor is a common reason why the VAZ 2114 cooling fan does not turn off.

Coolant temperature sensor

In this case, the system “thinks” that the liquid temperature is constantly high and does not drop (after all, the sensor is stuck at maximum), so no command is received to turn off the fan. To solve this problem, you will also have to purchase a new sensor and install it in place of the old one. If the fan starts working properly, then the sensor was the cause. If not, then the last possible malfunction remains - the electronic control unit.

Speaking about the temperature sensor going off scale, it is worth noting one very important point. If the cooling fan runs constantly, but the temperature on the dashboard is displayed correctly, then you can continue driving the car. If the fan does not turn off, and the instrument in the cabin shows boiling coolant, then trips should be stopped immediately and a full diagnosis of the cooling system should be carried out. This will help prevent engine overheating and failure.

Electronic module

As already mentioned, if all other elements of the electrical circuit are working properly, but the VAZ 2114 fan still does not turn off, all that remains is to check the last important link - the electronic module. It is worth noting that it rarely fails, but sometimes it does happen.

In this case, a solution to such a problem could be either a complete reset of all errors in the block or its flashing. Since it is quite difficult to do this at home, the best option would be to contact a car service.

ECU VAZ 2114

Diagnosis

Piston knocking in an engine can occur for various reasons. Try to determine the nature of the knocking by the signs listed below and see what you can do:

• The first case is a knock when moving the piston. In this case, the sound comes from the area at the top of the engine block. The knock is dull and is best heard at idle when the engine is hot. Solution.
• Case two - knocking of the piston pin on the connecting rod. A sharp short knock from the engine block area. Solution.
• Case three - connecting rod knock. The knocking sound is low and comes from the bottom of the engine block. It is best heard when the car is on a lift or on an overpass. Solution.

What needs to be fixed?

“Piston reversal” is the point at which the piston stops moving up and starts moving down. At this moment, its speed in the longitudinal direction of the cylinder becomes zero, and the lateral load is significant. In a normal case, the shift occurs gently, the piston rests against the oil film and does not warp. The piston begins to knock in the following situations:

• Significant wear of the cylinder in the upper part. A gap appears that is not sealed by an oil film, and when the direction changes, the piston in this gap moves laterally and warps, hitting the cylinder wall.

• The piston pin mounting sockets in the piston have worn out. In this case, the piston begins to move relative to the pin and touches the cylinder walls.

• Curvature of the piston rod. In this case, the piston does not move strictly along the axis of the cylinder, and the symmetry of the mechanism is lost. An additional sign of a bent rod is increased vibration when the engine is running; it shakes noticeably.

How can I fix this?

In the last of the cases described, only repairs and replacement of the piston group will help.

If the problem is the knocking of the piston in the cylinder or the wear of the piston pin seats, the use of a tribotechnical composition of the “Active” series, which is added to the engine oil, will help. The composition cleans the friction surfaces, and then under its influence a protective metal layer is formed on them.

• The layer restores the geometry of the cylinder, optimizes clearances and prevents rocking and distortion of the piston.

• The layer restores the shape of the seats, preventing play of the piston pin.

Do you have a car with a non-boosted gasoline engine up to 1.6 liters?

Do you have a car with an engine larger than 1.6 liters?

Important!

The tribo composition will have an impact and restore worn surfaces. However, it is not capable of restoring parts due to mechanical damage.

The composition is safe for your car. It is chemically neutral and does not change the properties of motor oil. The composition works in engines of any design, since it is activated in friction zones of metal parts. The active particles of the composition are tens of times smaller than the cells of oil filters and are not capable of clogging it. The compound restores worn surfaces, allowing parts to operate within factory tolerances even after an oil change and removal of the compound from the engine.

Bonus!

The tribological composition optimizes friction clearances. This equalizes and raises compression, reduces energy loss, and ultimately leads to lower fuel consumption. The car will return the cost of the train to you after 15-18,000 kilometers.

What needs to be fixed?

In case of wear and tear of the connecting rod bushing, it is able to move relative to the piston pin, when the connecting rod goes up, at the highest point of the piston, a gap is formed between the bushing and the pin. When the connecting rod begins to move downwards, this gap is reduced, and the bushing hits the piston pin.

How can I fix this?

In the early stages, this problem can be solved with the help of a tribotechnical composition of the “Active” series, which is added to the engine oil. The composition cleans the friction surfaces, and then under its influence a protective metal layer is formed on them. This layer is able to compensate for increased clearances, soften the contacts between the bushing and pin and significantly slow down subsequent wear.

Do you have a car with a gasoline engine?

Do you have a car with a diesel engine?

With significant wear, and therefore with a louder and more pronounced sound of impacts, it is necessary to repair the piston.

What needs to be fixed?

Connecting rod knocking occurs for two reasons:

• Wear of crankshaft bearings. In this case, a gap appears and the piston begins to move out of sync with the crankshaft, hitting it when changing the direction of movement.

• Insufficient oil pressure in the system. This may occur due to contamination of the oil passages, filter, or wear of the oil pump. In this case, the oil does not form a continuous film between the liner and the crankshaft and allows them to move relative to each other.

How can I fix this?

If the wear of the liners is not critical and there is no surface damage, the tribotechnical composition “Active Plus” will help. The composition cleans all units that are lubricated with engine oil, in particular it cleans the crankshaft journals and oil pump parts. Then, under the influence of the composition, a protective metal layer is formed on the friction surfaces, which restores the shape of the parts and is able to more firmly hold a denser film of oil.

Additional recommendations

If desired, you can install an additional button that will forcefully start and stop the fan.

In order to do this, you will need:

• purchase a button (or toggle switch) and mount it in any convenient place (you can even under the hood);
• make a branch from the wire coming from the battery positive to the fan relay, soldering another wire to it;
• connect this wire to the first contact of the button;
• connect the second contact of the button to the relay leg, from which the “positive” wire goes to the fan.

Thanks to such a simple circuit, it will be possible to control the operation of the fan manually.

Replacing the fuel filter yourself

Before performing work, it is necessary to drive the car onto an overpass or pit. After this, you need to find the necessary filter. In this car model, it is located under the bottom of the vehicle behind the fuel tank, next to the muffler. After this, you should unscrew several fittings (pipes). It is best to do this using key number 19 M.

If everything is done correctly, the filter can be easily removed. You just need to remember which side it was installed on. After this, it is enough to put the new filter in the same place in the correct position.

If the VAZ 2114 stalls, there may be other reasons. Therefore, it is worth considering them in more detail.
