The cooling fan on the Lada Kalina does not turn on

Modern domestically produced cars are equipped with various types of controllers and sensors that ensure full functionality of the car. If one of the devices fails, this may cause the units to malfunction. From this material you will be able to find out what the Priora and Kalina fan switch is, and what malfunctions are typical for it.

If the Lada Kalina cooling fan fails, you should immediately find the cause and eliminate it. If the machine boils over, it can have fatal consequences. At best, the gasket is damaged, and at worst, the cylinder head is deformed, which will lead to its forced replacement. Therefore, it is worth monitoring this device and conducting regular diagnostics.

How to find the reason

Let's start by checking the electric motor. Disconnect the electrical wires and connect directly to the battery, observing the polarity. If the fan doesn't start, that's the problem. If it works, you need to look for another reason.

Check all contacts on the connectors, as well as behind the relay and fuse. They are located in an additional mounting block, which is located on the right side of the instrument panel next to the lower heater duct.

The fuse (50A) can be checked with a tester; it is better to take a working relay and install it in the appropriate socket. If the problem is not resolved, continue.

Check temperature sensor. Warm up the engine to operating temperature, stop the engine and disconnect the sensor. It is located on the top of the thermostat housing. When the sensor is disabled, the controller must independently start the fan for continuous operation.

Start the engine and wait until the fan starts. If the coolant temperature has reached a critical temperature and the fan does not turn on, look for a broken wiring.

Do I need to change the fan?

If you determine that the problem is in the fan itself, or more precisely in its motor, you can try to fix it. Most often it stops working due to broken brushes or problems with the rotor bearings. The commutator or winding crack is rarely damaged.

If the fan cannot be repaired, it must be replaced.

Under no circumstances should you drive a vehicle with the fan not working. Overheating of the engine inevitably leads to the destruction of rubber hoses of the cooling system, seals, and can also cause failure of the piston group elements.

Air lock: features

"Kalina", like hundreds of other cars, is in no way protected from the appearance of an air lock. It cuts off the coolant supply. Solving this problem often involves some difficulties.

For a novice motorist who owns a Lada Kalina, an air lock is always a problem. To deal with it, you first need to remove the cap from the expansion tank. Then heat the engine to a temperature at which the gauge needle begins to reach the red zone. When the fan turns on, you need to press the accelerator pedal several times and turn off the ignition. Sometimes this is enough. The air lock completely disappears.

However, if the plug remains, more specific measures must be taken:

The plastic screen is being dismantled;
the clamp is released;
the tube is removed from the fitting located on the throttle assembly;
the expansion tank opens, its neck must be closed with a rag;
Air is supplied to the open expansion tank until liquid begins to pour out of the tube. If it was not possible to break through the air plug in this way, you need to close the lid and return the removed tube to its place.
then you need to warm up the engine again and turn off the ignition;
remove the heating tube, but do not remove the cover. You need to wait a little until the liquid begins to pour out of the tube.

Since coolant is a toxic substance, this operation must be performed very carefully. Safety precautions require gloves.

During operation, you need to check the temperature of the tubes. The engine must be completely cool.

After draining the liquid, the tube is put on the fitting and tightened with clamps. Thus, the air from Kalina will be completely removed. This work can be done by any motorist; the help of a specialist is not needed. In order for Kalina to be free from such problems, it is necessary to constantly check the tightness of all connections and tighten the clamps.

Is there a need to replace the fan?

Having determined that the fan or electric motor is faulty, you can try to repair it. Firstly, in Kalina 1.6 (8-valve), the cooling fan does not turn on if the brush is damaged or the rotor bearings fail. Less often, the problem should be in the distributor or winding breakage.

If the device cannot be repaired, the component must be replaced. Do not attempt to drive a vehicle with a damaged fan. Overheating of the engine automatically leads to rupture of hoses, wear and improper use of seals. action of the pistons.

Replacing relays and fuses

These protective and fan control components are fairly easy to replace. We remove the burnt element from the mounting socket and install a new analogue. It is convenient to use suitable tweezers here.

Looking for a reason

Start checking with the electric motor. To do this, disconnect the electrical wires from it and connect directly to the battery, observing the polarity. If the fan doesn't start, that's the problem. If it works, you need to look for another reason.

The fuse (50A) can be checked with a tester; it is better to take and install the relay. into the appropriate slot. If the problem is not resolved, continue.

Check temperature sensor. To do this, warm up the engine to operating temperature, turn it off and disconnect the sensor. It is located on the top of the thermostat housing. When the sensor is disabled, the controller must independently start the fan for continuous operation.

Start the engine and wait until the fan starts. If the coolant temperature has reached a critical temperature and the fan does not turn on, look for a broken wiring.

If you determine that the problem is in the fan itself, or more precisely in its motor, you can try to fix it. Most often it stops working due to brush failure or problems with the rotor bearings. The commutator or winding crack is rarely damaged.

If the fan cannot be repaired, it must be replaced.

Improvements

Also, you can upgrade the cooling system, which will prevent the risk of getting “stuck” in the middle of a city or highway. To do this, you need to install a more reliable thermostat. Some car owners recommend altering the factory system and installing a 6-hole thermostat, as well as installing an additional furnace valve with 1 more pump.

The second upgrade option is to install a sports fan with a separate controller, which will show the functionality of this system. Although you will have to make some design changes to the car's electrical circuit.

In order to reduce the risk of encountering such a problem, you can display an additional button on the instrument panel to force the cooling fan on the Lada Kalina. To do this, wires are run in parallel and, if necessary, or in cases of thermostat failure, the fan can be forced to start.

Description

It is known that every Priora and Kalina has a cooling system that ensures normal engine operation and prevents it from overheating. One of the cooling devices of the unit is a fan sensor, the signal from which activates the ventilation device.

In Kalinas devices, this controller is designed so that it turns on the fan when the engine temperature reaches a certain point. Thanks to the fan, which must turn on according to a signal from the controller, the engine temperature will always be normal and will not exceed the permissible threshold. If the device does not work, the fan does not turn on, and the engine may overheat.

Main functional elements of the cooling system

Before you figure out why the Kalina engine cooling fan does not work, you should understand what the cooling system consists of in general. This may include:

radiator. It is located at the front of the vehicle. The cooling process is carried out using a powerful air flow;

fan. The device is located on the radiator itself. When the antifreeze temperature reaches a certain value (on viburnum it is 95 degrees), the fan starts working, which speeds up the cooling process;
temperature sensor. It sends a signal to start the fan when the motor temperature begins to rise;
expansion tank. Antifreeze reacts very sharply to temperature fluctuations. When it contracts or expands, the expansion tank allows it to compensate for the change in fluid volume;
water pump. Thanks to the pump, antifreeze circulates throughout the system;
thermostat. The device is responsible for the process of supplying fluid to the radiator. It is this element that controls and maintains a stable temperature in the power unit.

A breakdown of any device leads to a situation where the cooling fan on the 8-valve Kalina does not work.

Next in the video is a solution to the problem when the cooling fan does not turn on in Kalina:

The main reasons why the radiator cooling fan does not work

Let's look at the main options and where to look for faults:

Thermostat. The thermostat from the Lada Kalina has been removed; if it fails, this is the reason that the cooling fan does not work properly. To diagnose this problem, you need to touch the down tube. If it's cold, the thermostat is dead. Many owners of Kalina cars are accustomed to this phenomenon, since it often breaks down, and they carry a spare tire.
If it's not the thermostat, the next step is to check the fuses. You need to make sure that they work and all the drivers too. The easiest way is to check them with a tester or ohmmeter. The fuse diagram can be found here. The relay box with fan fuses is located under the distribution console, next to the controller. The fan fuse has a capacity of 50 A and is designated number 3. The fan relay is number 1. Relay and fuse box. If the fuse is blown, you will have to remove the optional fan control unit. To do this, move the warm air duct to the side and use a 10 mm wrench to unscrew the fastenings of the device. Now it can be easily removed. It has two relays that are responsible for turning on the fan and for high speed. Let's diagnose them both.
Now you can move on to the darkest option - climb under the hood and “feel” the contact wires of the fan itself. Sure, there could be a cracked or broken wire, but there's nothing worse than a burnt-out winding inside the fan. In this case, the fan probably needs to be replaced.
Another reason why the fan won't turn on could be a faulty thermostat sensor. To start the fan in emergency mode, disconnect it from the power supply. You can check the sensor by removing the thermostat and dropping it into a pan of hot water; the thermostat should open.
The last reason why the fan may not work is a break in the circuit itself. Cooling fan wiring diagram

The thermostat was removed from the Lada Kalina.

If it is damaged, then this is the reason why the cooling fan is not working properly. To diagnose this problem, you need to touch the down tube. If it's cold, the thermostat is dead. Many owners of Kalina cars are accustomed to this phenomenon, because they do not often carry a spare tire with them.

The relay box with the fan fuse is located under the instrument panel console next to the controller. The fan fuse is rated at 50A and is number 3. The fan relay is number 1.

Relay and fuse box

If the fuse is blown, you will need to remove the auxiliary fan control unit. To do this, move the warm air duct to the side and use a 10 mm wrench to unscrew the bolts securing the unit. Now it can be easily removed. It has two relays that are responsible for turning on the fan and for high speed. Diagnose both.

DIY fault repair

We will not talk about solving problems such as failure of fuses or the sensor itself. Everything is so simple here - failed elements are removed from their installation locations and replaced with new ones.

Separately, it is necessary to highlight the replacement of the ventilation unit - read about this below:

So that during the repair process you do not have to dismantle the radiator, do everything carefully, since there is a possibility of damage to other elements.
Open the hood and disconnect the battery. Remove the air filter.
Having done this, you can dismantle the radiator grille.
Next, you will need to unscrew the top mountings of the optics - the right and left lights.
Using a 10mm wrench (it will be more convenient to take a socket wrench), you will need to remove the upper front panel.
After these steps are completed, you will need to disconnect the plugs that are connected to the ventilation unit. Having done this, the wires can be twisted a little.
Next, using a wrench, you will need to unscrew the four screws that secure the device to be replaced. The arrows in the photo indicate the screws that secure the assembly; they will need to be unscrewed.
Only after the unit is freed will it be necessary to dismantle it and replace it with a new one. After removal, just in case, clean the connectors themselves so that in the future you will not be bothered by the problem of poor contact. Further assembly of the system and installation of all elements is carried out in the reverse order.

How to replace a fan

Having carefully figured out why the cooling fan of the Lada Kalina does not work, the faulty element must be replaced. If you have the necessary skills and dexterity, you can do the repairs yourself. The tools you need to prepare are pliers, a screwdriver, wrenches 8 and 10.

First, park the car on a level surface. Then lift the hood, disconnect the system from the ACB. Using a wrench, unscrew the air filter mounting bolts. Then disconnect the mass air flow sensor (simply press the latch) and the purge valve, which is located on the air filter housing. Unscrew the fastening screw and remove the folding machine.

Remove the air filter cover, remove the filter element, and remove the air intake. Then attach the fan cover and turn off the power to the fan. Once all of the above steps have been completed correctly, you can begin disassembling the fan.

A few final words

We learned how to check the cooling fan on Kalina. Once again I would like to emphasize that the operation of this element is very important for the functioning of the entire vehicle. Under no circumstances should you drive your car if the fan is broken. And if there is a need to get behind the wheel of such a vehicle, be sure to make stops at least every 5 minutes.

Below is a detailed video about the reasons why the engine cooling fan does not turn on on the Lada Kalina:
