The VAZ 2114 engine fan does not work. The WAZ Cooling Fan Connection Scheme. Zone finding a problem

The fan is used to form air flows, which are sent to the engine radiator. This is necessary in order to cool the liquid that circulates on it.

If the car moves at high speed, the fan is not particularly required, since all the necessary cooling the motor receives from the oncoming air flows. But when the machine goes into a slow drive mode or downtime with an engine turned on, the propeller role becomes indispensable.

The desired device

Turning on occurs after the appropriate signal is filled from electronic block Control. ECU, in turn, learns about the need to turn on the fan from the temperature sensor. The inclusion threshold is 103-105 degrees Celsius.

In the case of the VAZ 2114 fan (propeller) is in open space With the back of the radiator.

Why he doesn't work

There are several reasons due to which the propeller may not be included when the situation with temperature indicators requires:

• The fan electric motor failed, that is, the drive;
• There was a breakdown of the fuse, which burned down;
• Relay refused;
• Wiring broke;
• Sensor connectors lost contacts;
• The sensor failed.

Find a malfunction

Zone finding a problem	Explanation
Check propeller	The connector on the propeller is turned off and connects directly to the battery. If the fan has earned, everything is fine with the drive. If the propeller still did not twist, the problem is in the electric motor
Wiring and contacts	If the propeller does not work, it is necessary to check the condition of the wiring and make sure the sensor contacts
Fuse	You can find these two elements in the open space to the left closer to the driver inside mounting block. A fuse is a fuse with the designation F4 with a rated current 20a. Check can be performed by pressing the sound signal button. Why? Yes, because it is also connected to this fuse. Or spend check tester
	Located in the same place where the fuse. For effective checks, it is best to take a relay, in the performance of which you are 100% sure, set it to the place of old and check
	To check the sensor, disconnect the power from it. If it works, the propeller will start working in emergency mode, that is, it will constantly blow. Disconnect the connector and turn on the ignition. If the propeller is tightened, then the sensor is broken. Need replacement

When to change

If the cause of all problems was the fan itself, it is not necessary to change it, since in some cases it can be completely repaired. The breakdowns are often associated with bearing or brushes.

If the cause of the breakdown is the failure of the electric motor due to the cliff of wiring or closure, it is not worth risking with its repair. It's easier and better to replace the entire drive.

Chain check

If the cooling propeller does not work, it will lead to overheating of the coolant and the destruction of the nozzles, rubber elements, the gaskets of the main cylinder block and the valve cover. Not far to the destruction of the components of the piston group.

Fuse

The operation of the car with a broken fan is strictly prohibited.

Question price

Before you begin to solve the problem with the non-working propeller of the radiator, it is important to know many of the cost of components and work.

The new element will cost about 1.5-2.5 thousand rubles today, depending on the model and region. Replacement cost at the station maintenance will be from 400 rubles and higher. Although it is not necessary to spend money for it because independent replacement It will take you no more than half an hour. Yes, and there is nothing difficult here.

Replacement

In order to replace the fan cooling propeller with their own hands, you will need enough small set Tools where:

• Crosshead screwdriver;
• End key for 8 millimeters;
• The end key is 10 millimeters.

If you are ready, then start working.

1. Install the car on a flat pad, turn on hand brake. Just in case, under the wheels of your VAZ 2114, you can put additional supports. Precautions will never interfere.
2. Raise the hood, turn off from rechargeable battery Minus terminal.
3. Using the key of 10 millimeters, the fasteners of the air filter housing are dismantled.
4. Armed with a screwdriver, loosen the clamp from the duct located on the sensor mass flow air. So you will be able to remove the corrugation. Do it.
5. On the cover of the air filter housing there are self-tapping screws that hold it. They are twisted with a screwdriver, after which it gets from landing Filtering component.
6. Take now the key on 8 millimeters and dismount the air intake fastening, then remove the air intake itself.
7. Now the key to 10 and 8 millimeters is removed the fastening nuts on the fan casing throughout the perimeter. In total, there you will find 6 nuts.
8. Disconnect the shoe from the wire from the connector of your broken fan.
9. Remove the fan cover, capturing the actuator, that is, the electric motor.
10. Armed with a key of 10 millimeters, you need to dismantle three fastening bolts that keep the electromotor on the casing.
11. Install the new fan to the place of the old device.
12. We return all fasteners to the places, connect the connectors, perform the assembly in the reverse sequence.

After installing the new equipment, be sure to turn on the engine and let it work for a while. Until the inclusion of the fan and the propeller does not twist. It will take no more than 5 minutes. Soon the fan must turn off itself. If he did not stop, turn off the motor. Repeat the experiment.

It rarely turns out that after replacing the fan still does not work. Even if this happened, it is associated with two possible events - other elements of the cooling system were affected, or you purchased a non-working fan. Alas, given the number of fakes on the market, it is impossible to exclude the second option.

Each driver knows that engine overheating is very bad. It can not give anything good. In order to protect the motor from overheating, cars are equipped with radiator cooling fans. And sometimes it is far from one.

Today we will talk about a very important cooling element - fan sensor. It is responsible for the timely turning on this cooling device, preventing unwanted overheating.

A bit of theory

Characteristic	Explanation
Location	Located sensor in the stove radiator. It is not difficult to determine which in front of you it is not difficult because it is the only element in the radiator to which the wires are connected. And if you take the key to 30, then only the sensor has the appropriate fastener size.
Treatment temperature	Sensors may have different temperature limits. But for VAZ 2114, the inclusion occurs at 102-105 degrees Celsius, and shutdown - at 85-87 degrees. When choosing a new meter, focus on the one that has failed, or purchase 102 and 87 degrees from the inclusion and shutdown indicator, respectively
Operating principle	Inside the sensor has a special contact group. When heated coolant in the radiator, this group is heated and expands. When the extension comes to a certain limit, the contacts are closed, they transmit a signal to wiring and the fan turns on

Causes of fan breakdown

There are a number of reasons due to which the fan sensor may eventually fail in addition to the sensor. Therefore, they should be pre-eliminated to make sure the sensor throughout the wine.

For reasons for refusal of fan work:

1. Fallen fan. It can be worn, lose integrity, get mechanical damage. It will be more expensive to replace it if you compare with the sensor, but there is no choice.
2. The chain broke. When checking the sensor, the method of closing two contacts is usually used. But if the wiring chain has damage, it will not be possible to do, and the entire fault by inexperience is welded to the regulator.

If the verification of the contacts did not give the result, the fan does not respond, try to connect its contacts directly to the rechargeable battery.

Sensor check

Plus necessarily check the new sensor before installing it. This will make sure of its performance. Today, fakes are quite much on the market, therefore there is always a chance to purchase a not high-quality fan sensor.

To verify you need a certain set of tools and materials, which includes:

• Capacity;
• Water;
• Coolant;
• Thermometer;
• Multimeter.

We proceed to check.

1. Pour water or conventional cooling fluid into the prepared container.
2. Lower the sensor in the threaded part.
3. Multimeter terminal Connect with regulator contacts. The measuring device must stand in resistance measurement mode. Although if the multimeter has the function of the transvers, then choose it.
4. Place the thermometer in the liquid.
5. Heat water.
6. When the fluid temperature reaches the operation temperature of the regulator (92 degrees Celsius), the contacts must be closed, and the multimeter will begin to squeeze.
7. If this did not happen, the sensor does not work and it requires a changering.

If you purchased a non-working regulator, be sure to go to the store and require a replacement or return of money. But only if there is a check. It is better to acquire spare parts in specialized, good stores. The risk to get to the fake there is less.

Replacement

On the injector Enginewhich is literally overflowing with all sorts of sensors, sometimes you need to pay attention to the fan power regulator. If the check showed that the device failed, nothing else remains except to carry out the replacement procedure.

The work implies the need for only several tools and materials:

• Claw key for 30 millimeters;
• Packaging for draining liquid cooling;
• Dry rags.

Prepare everything you need can be replaced.

The first priority is to make the engine to cool. Working on a cold engine is more convenient and safer. If the hot cooling fluid falls on the skin, burns can not be avoided.

1. To replace you, you will not need an observation pit or an overpass. With such works, these items are not needed. Suitable a simple garage.
2. Disconnect the minor terminal from the battery.
3. Drain the entire cooling fluid from the radiator. From the cylinder block, do not merge, there is no need for it.
4. Remove the cork from the expansion tank of the cooling system of your injection engine.
5. To drain Tosol or antifreeze, unscrew the drain plug on the radiator. You will find it from the bottom of the radiator, and to dismantle the tool will not need. The plug is easily twisted manually.
6. Under drainer Substitute a pre-prepared container where the coolant will flock. Wait until flowing fluid fails.
7. If you want the same toxol then pour back, take clean capacity. If the coolant is old enough and needs to be replaced, then the purity of the container does not matter.
8. Screw the cork back.
9. Disable contacts from the sensor fan.
10. With the key of 30 millimeters, the regulator is unscrewed.
11. Spin carefully, in order not to damage the plastic container of the radiator.
12. Screw to the place of the old new regulator. Be sure to insert a copper gasket for a new device.

1. Return the fan controller electrical wiring.
2. Fill in expansion tank Fused in advance toosol or antifreeze.
3. Perform the purge system to avoid education aerial traffic Inside the system.
4. Return a minor battery terminal to the place.
5. Turn on the power unit, warm it up for a while to make sure the performance of the new sensor.
6. If, when heated to the desired temperature, the sensor does not respond again, you should check the other items that may be the cause of this behavior of the cooling system.

Replacement without draining

If you do not want to spend a lot of time on the replacement of the sensor on its VAZ 2114, you can do without draining the cooling fluid drainage.

Replacing the fan power regulator without a stage of draining coolant requires experience and certain skills. Therefore, the newcomer is not recommended for this method of repair.

• Using the key for 30 millimeters, start unscrewing the old sensor, but not to the end.
• Prepare a new sensor.
• Out with one hand to the end of the old regulator, and the second to insert a new one.
• At the same time, a certain part of Tosola follows, but it is not scary.
• After replacement, you must thoroughly wipe all areas near the regulator using a dry vet.
• Make sure that there are no leaks after installing a new device.

After completing the work, carefully wrap the car so that the coolant remains on the engine and its components. This is especially true of rubber and plastic elements.

Overheating of the engine leads to serious problems: the piston can be encouraged, the laying of the cylinder block makes itself, which leads to the need to carry out overhaul Motor. To protect the power unit from overheating, it is important to support stable work Cooling fan. In this article we will discuss the principle of operation of the device, the scheme of its connection, independent diagnosis and repair, as well as upgrading the control circuit. The instruction is fully suitable for cars VAZ 2115 and VAZ 2113.

Operating principle

The fan is a device that allows you to increase the efficiency of the cooling radiator. The radiator takes heat from the motor and gives it to the air. This process is accelerated by blowing the blades of the electric fan.

The coolant flows through a closed hermetic system. Her task is to take excessive heat from the superheated parts of the engine. Hot Tosol flows into the radiator, exposed to cooling and returns back. While in the radiator, the coolant passes through the system of thin tubes. The incident air flow during the movement of the car contributes to the rapid diversion of excessive heat from the boost space.

But when the car stands in a traffic jam or works on idling, Air flow ceases to cool. In this case, the cooling system may not cope with its task. To create air flow by artificially, the radiator electric fan is intended. Fan power on VAZ 2114 - 85 degrees Celsius.

Having received a signal of exceeding the permissible temperature value, the sensor starts the mechanism of the device. It creates an artificial airflow, removing heat from the radiator. The mechanism is valid until the temperature level is reduced to the optimal state.

Then the thermal switch receives a signal about reaching the normal temperature and turns off the fan operation.

The device consists of four plastic blades that are installed on the EDG shaft. Special controller regulates automatic operation. The thermostat is equipped with a solid filler, which is sensitive to temperature changes.

There is main and additional valves. When the temperature reaches 85 degrees Celsius, the master valve opens.

Connection scheme

Where is the fan relay

It is located in an additional block.

4 - relays of the electric fan;

5 - electric fuel pump;

6 - ignition relay.

Relays and fuses may have a different order. Therefore, you need to navigate the color of the wires. The main relay is always placed below. Find the relay from which the pink thin wire with a black stripe stretches. It comes from the main relay through contact 85. Be careful! Do not confuse with a red thin wiring, which also has a black strip and stretches from the controller. And find a white thick wire with a black stripe (87 contact). Here is the cooling fan relay. Next to him is always a fuse. It is a chain element.

Diagnostics of fan cooling

If on dashboard There are signals about exceeding the permissible level of temperature in the cooling system, this may indicate that the fan does not work on the VAZ 2114. The main symptom of malfunction - the mechanism does not start even with a significant increase in temperature. It is urgently to drown out the engine to prevent overheating of its elements.

The motor should not work with a faulty cooling electric fan. This can cause damage to the head of the cylinder block.

If the cooling fan does not work on the VAZ 2114, the following faults may be causes:

• Refused the fan power sensor on the VAZ 2114.
• No contact at the sensor connector.
• Wiring broke.
• Malfunction of the relay of the electric fan.
• Fuse burned.
• Equipment breakdown device device.

Disconnect the device connector. Connect it to the battery terminal. Saving polarity. If direct connection to the energy source starts the electric motor, then the drive is working. Perhaps the problems occurred in the wiring, in the fuse or in the temperature sensor.

Now the fuse diagnostics has arrived. For this, it is not even necessary to open the plastic box. If the relay fails simultaneously with the fan ceases to work and clickson. Therefore, if you notice the loss of the sound signal, then the fuse has accurately burned down. It is possible to find it in the workpiece in the plastic box of a small size. We release the lid, pressed by two latches, pulling the burned fuse with tweezers and change it to the new one.

But diagnose the relay is quite difficult. Especially those who are with auto electrician solely on "you". To check the performance, the easiest way to find a working relay and temporarily install it. If, after installing the new device, the fan begins to work properly, then it is time to replace the old one.

To diagnose a temperature sensor that feeds the signal to the radiator, you need to disconnect the connector from the sensor and start the ignition. Emergency mode will start, in which the electric fan will start blowing. If the fan starts when the connector is turned off late, most likely the sensor has failed. Its replacement will take no more than five minutes. You just need to unscrew two bolts using a crosst screwdriver and install a new device in its place.

Even if the fault arose in the fan itself of the VAZ 2114, it does not mean that it was time to change it. Sometimes you can simply replace the damaged bearing or brush. But when the electric motor is faulty, it is much easier to acquire a new mechanism.

How to replace

If you are convinced that the cause of the fault lies in the fan electric motor, then the easiest way to repair is to completely replace the device. It makes no sense to spend money on a new casing. Cheaper will simply buy a new electric motor.

Required tool

The special tool will not need. The work is carried out elementary simply using end keys on 8 and 10 and crusadum screwdriver.

Step-by-step work algorithm

Replace the cooling fan electric motor without dismantling the radiator.

1. Disconnect the block and harness the wires of the device from the casing.
2. Unscrew the mounting bolts using the key to 10.
3. Unscrew the bottom mounting nut.
4. The end key on 10 turn the fastener nut from the radiator.
5. The end key to 8, unscrew the two knitting plates nuts.
6. Remove the plate.
7. Remove the electric fan with the casing.
8. We proceed to dismantling the electric motor. Using the key to 10, roll three mounting nuts and remove the engine along with the blades.
9. Using a screwdriver, let's swing the lock washer.
10. And remove it.
11. Remove the impeller.
12. Nadid the impeller on the new motor. Make sure the shaft pin hit the groove of the impeller.
13. Collect the assembly in the reverse order.

How to replace temperature sensor

Before starting work, it is necessary to partially drain the cooling fluid from the cylinder block.

What if the electric fan works constantly?

Sometimes another problem arises. Many motorists are interested in why the fan is constantly working on VAZ 2114?

Four causes of malfunction are possible:

1. there was a closure in electrocups;
2. there was a breakdown of the relay of the electric fan;
3. requires a replacement thermal sensor;
4. the electronic unit broke.

Most often, the fan begins to work incessantly as a result of the closure of the wires. The electrical circuit remains in the on state, regardless of the thermal sensor signals and the relay.

To eliminate a malfunction, you need to ring each wire and find the place of fusion. Sometimes it is noticeable even with visual inspection.

If the transk does not help identify a malfunction, you need to check and replace the fan relay. The cost of the device is low. Therefore, it is easier to buy a new relay for diagnostics and put it instead of old.

If it does not help, it means that you need to check the operation of the thermal sensor. After all, it is he who is responsible for the inclusion and shutdown of the electric motor of the VAZ 2114 fan.

For good job All other system elements, you need to check the electronic module. It rarely fails. If the problem arose still in it, you have to complete a complete reset of errors. Sometimes only complete flashing is helped. Not everyone is capable of doing this job. Therefore, it is better to seek help in the car service.

It would also be useful to set the forced start button and turn off the fan on the VAZ 2114.

This decision may turn out to be quite by the way if the breakage occurred somewhere on the highway away from the city. In this case, using the button on the instrument panel, you can force the fan operation for cooling the engine.

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

This node often fails, which requires both the replacement of the fan itself and the various components that manage its work. We will tell you more about why the cooling fan is not included on the VAZ 2114 and how to repair your car.

Symptoms of malfunction

Determine the presence of a problem in the operation of the cooling system fan, it is possible to quickly increase the coolant temperature. The appropriate warning message appears on the car dashboard on the growth of the coolant temperature. Car owner should be drowning the engine and wait for its cooling, after which it can be carefully continued to move. Remember that it is not recommended to operate a car with such a non-working fan, since there is a risk of damage to the head of the cylinder block, which consistently forces the labor-intensive and expensive repair.
You can also identify such damage by visual inspection of the radiator and the fan. If, with a significant increase in the temperature of the coolant, the fan does not turn on, this may indicate the presence of various breakdowns of this node.

Causes of fan malfunction maybe several:

• Temperature sensor breakage.
• Digging contact with the temperature sensor connector.
• Cutting wiring.
• Relay problems.
• Fuse blocked.
• Fault Drive Fan Electric Motor.

Required tool

The choice of the tool used will be directly dependent on the nature of the breakdown. Often it is enough to open the box with the relay and change the blown fuse to a new one, which will allow you to restore the performance of the fan. Whereas with a significant breakdown, when the cooling fans of the VAZ 2114 are not included, it is required to remove the radiator, remove the fan or change the relay and the corresponding temperature sensors.
To remove the fan you will need:

• Crosshead screwdriver.
• End keys on 8 and 10

Step-by-step work algorithm

In each case, the repair of the fan will differ depending on the existing breakage. It is necessary to conduct appropriate diagnostics, which will determine why on VAZ 2114 does not turn on the radiator cooling fan in a timely manner, which will simplify the subsequent repair.
First of all, it is recommended to turn off the fan connector, after which the polarity comply with the connector directly to the battery terminal. In the event that, with such a direct connection, the fan begins to rotate, this indicates a good drive, and the reason in this case It may be in wiring, faulty temperature sensor or safety problems.


Check the fuse that is responsible for the cooling fan, without opening the plastic box. The fact is that the relay is dual and at the same time responsible for the work of Klasson. Therefore, if the car has a sound signal and the fan does not work at the same time, this indicates a distinguished fuse. The block with such relays is located under the hood in a small plastic box. To open it, you should remove the two latches, after which the tweezers get and change the fuse you need.


Relay breakdowns are difficult to diagnose. We can recommend that you get a 100% working relay, temporarily set it into the landing socket and check the correctness of the fan. If, with such a check, the fan will work, then it should be simply replaced by the relay used to work.


To check the temperature sensor, from which the signal comes directly to the radiator, turn off the connector from the sensor, and then turn on the ignition. In this case, the automation starts the fan to the constant blowing in the emergency mode. In the event that, with such a shutdown of the connector from the sensor, the fan is late turns on, respectively, we can conclude that the temperature sensor failed, which will require replacement. The temperature sensor itself is fixed by two bolts, unscrew which can be a simple cross screwdriver. Such a replacement of the sensor usually takes no more than 5 minutes.


If the cause of the breakdown is still a fan, you can try to repaired it first or immediately replace the new one. The problem can be in the bearing or brushes. In this case, you can replace such damaged detailsthat will allow you to fully restore the cooling system fan. If the cause of the fan breakdown is an electric motor, then the repair represents certain difficulties, and such a resulting drive is best replaced with a new one.

To remove the fan with the drive you need:

1. Car VAZ 2114 is installed on a flat platform and tighten the parking brake
2. Open the hood and de-energize the minus terminal
3. The air filter housing should be unscrewed by a ten key.
4. Weaken the clamps at the duct
5. Twist the screws that fix air filter and get the filter element
6. Next, unscrew and dismantle the air intake, for which the key will need to eight
7. Remove the fan cover, for which the eighth key is unscrewed 6 nuts
8. Remove the motor block
9. Remove the fan with the drive

You can only install in place new drive Or the entire fan assembly and hold an assembly in the reverse sequence. After such a repair, check the correct functioning of the fan, for which the engine warms up and wait for the inclusion of blowing.

Conclusion

As you can see, the reasons why the cooling fan is not turned on to the VAZ 2114, there may be a set. Car owner It is necessary to carry out appropriate diagnostics, determine the cause of the breakage and self-eliminate it or completely replace the cooling fan.
