What to do if 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 replace a fan

Having understood exactly why the cooling fan of the Lada Kalina does not work, you should replace the faulty element. With the proper skills and dexterity, you can perform the repair yourself. The tools you need to prepare are pliers, a screwdriver, wrenches 8 and 10.

First, we place the vehicle on a level surface. Then we lift the hood and disconnect the system from the battery. Using a wrench, disconnect the air filter mounts. Next, you need to disable the mass air flow sensor (just press the latch) and the purge valve, which is located on the air filter housing. Unscrew the clamp bolt and remove the corrugation.

Remove the air filter cover, remove the filter element, and dismantle the air intake. Then we proceed to attach the fan casing and disconnect the power supply to the fan. Having done everything correctly, you can dismantle the fan. We remove the electric motor and then replace it with a new element. Then we put everything back together.

Finally, it is worth checking the functionality of the device. We start the engine and then warm it up for 3-5 minutes. The fan should turn on during this time. There is no need to turn off the car as soon as the fan starts spinning - you should wait until the device turns off automatically.

If malfunctions occur related to the operation of electrical accessories on the Lada Kalina, do not rush to get into the mechanical part. Maybe the problem lies in the combustion of fuses. But not all motorists know where the Lada Kalina fuse box is located and their markings.

What if the fan completely stopped working?

To determine the cause of such a malfunction, you first need to check the condition of the fuse in the electrical circuit. It can be found on the side console, near the passenger seat. It is hidden under the deflector cover. By unscrewing the screw, the cover can be easily removed and the fuse will be available for examination.

To remove the entire safety block and connected relays, the mount must be released. You can't do this without wrenches. You need to remove the unit carefully without haste, as you can damage the wires that are connected to it. Only the single fuse of the unit is responsible for the operation of the fan.

If the fuse is intact, it is necessary to check the operation of the relay that powers the fan motor. There are two such relays installed. The left one turns on low fan speed. And the one located on the right is responsible for the high speed of its operation.

Another problem that relates to the cooling fan relay is that the cooling fan continues to operate when the ignition is turned off. This may drain the battery. “Kalina” then simply won’t start. The main reason is sticking contacts. The block is exposed to antifreeze leaking from the radiator installed above the stove.

When the relays and fuses are working properly, you need to check the operation of the temperature sensor. It is he who orders the fan to start working. This sensor is located on the right side of the radiator tank.

To check its functionality, you need to remove the plug connector, take a jumper, and use it to short-circuit the connector terminals. The fan turning on indicates that the sensor is in good condition. If the fan does not react at all, then before changing the sensor, you need to check the functionality of the fan motor. To do this, the electric motor terminals must be connected to the battery contacts. The engine should start working. In case of failure, you will have to install a new electric motor.

Relay and fuse box Lada Kalina

Before replacing the fuse, the cause of the blown fuse must be determined and eliminated. To avoid failure of elements of the engine control system, do not install fuses with an increased rating or homemade ones. Sometimes the fuse thread remains intact, while its connection inside the fuse is broken. It is impossible to visually determine such a malfunction. In this case, you can assess the condition of the fuse using an ohmmeter. You will find a full description of viburnum fuses below.

Where is the Kalina relay and fuse mounting block located.

On the left side, behind the exterior lighting control panel.

Why the cooling fan does not work on Kalina

The radiator fan is used to force cool the engine radiator when it overheats. When the car is in motion, the radiator is cooled by oncoming air flow.

At low speeds, or when the car is just standing still, the radiator is not able to cool the liquid on its own, so when it reaches a certain temperature (101-105 degrees), the sensor is triggered, thereby transmitting the corresponding signal to the controller.

The latter analyzes the received information and turns on the fan.

The fan itself is a structure consisting of a casing (housing) with a built-in electric motor with an impeller. The fan is attached to the inside of the cooling radiator.

Description

As you know, any Priora and Kalina have a cooling system that ensures normal engine operation and helps prevent overheating. One of the devices that allows you to cool the power unit is a fan sensor, upon the signal of which the ventilation device should turn on. On Kalina, this controller is designed to activate the fan when the engine temperature reaches a certain point. Thanks to the fan, which must turn on based on 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 will not turn on, and the engine may overheat.

How to find the reason

Start checking with the electric motor. To do this, disconnect the electrical wires from it and connect it directly to the battery, observing the polarity. If the fan does not turn on, that is the problem. If it works, you need to look for another reason.

Check all contacts on the connectors, and then the relay and fuse. They are located in an additional mounting block, which is located to the right of the instrument panel near the lower heater air duct.

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

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

Start the engine and wait for the fan to turn on. If the coolant temperature has reached a critical value and the fan does not turn on, you need to look for a break in the electrical wiring.

Do I need to change the fan?

If you have determined that the problem is in the fan itself, or rather in its electric motor, you can try to repair it. Most often, it stops working due to failure of the brushes, or due to problems with the rotor bearings. Less often the collector becomes unusable or a break occurs in the winding.

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

Under no circumstances should you drive a car with a non-functioning fan. Overheating of the engine will inevitably lead to the destruction of the rubber hoses of the cooling system, gaskets, and also threatens the failure of parts of the piston group.

Modernization of Kalina SOD

The main problem of the Kalina cooling system is the formation of air locks. Today there are a number of effective ways to eliminate this defect. The reason lies in the design features of the SOD. The operation of the cooling system is based on the interconnected functioning of many parts. The use of the large and small circuits depends on the temperature of the antifreeze circulating through the system. The normal operation of the entire power plant depends on this.

You can modify the cooling system yourself or at a service center. Professionals rarely engage in all sorts of modifications, recommending replacing or repairing a particular component. This method may be more expensive, but not always more effective.

Classic ways of improvement

In order to solve the problem with the formation of air locks, you need to remove the expansion tank cap and start the engine. Then wait until the coolant temperature rises to the critical red zone until forced cooling by the fan comes into operation. After this, you need to press the gas pedal several times and turn off the engine.

If the method is ineffective, there is another method. To do this, you need to dismantle the engine protection, loosen the clamp and remove one of the tubes of the throttle body heating fitting. Then unscrew the cap of the expansion tank and, applying a rag, start blowing into it until antifreeze begins to flow from the removed pipe. In order to modify the standard cooling system, many car owners install a more efficient 6-hole thermostat, install a coolant filter and another heater faucet.

To increase circulation efficiency, an additional pump is often installed.

Other upgrade options

If the car is equipped with an electronic gas pedal, the hose that previously went to heat the throttle assembly is now looped into the cooling system. To prevent the formation of air pockets, an additional pipe with a smaller diameter is used, which is installed instead of the above hose. The hose for the air duct is placed near the thermostat; for this, a tee is used, mounted in the pipe fitting to the radiator. The second end of the pipe is connected to the steam removal hose near the expansion tank (you will need another tee).

The modification ensures a stable operating temperature of 90 degrees in urban conditions, and the stove begins to warm up at 50 degrees.

The next improvement method is to equip the steam outlet with a special hydraulic fence. To do this, a tube from a dropper is mounted in the steam removal hose, which is immersed in antifreeze at the bottom of the expansion tank. As it cools, the antifreeze is drawn into the outlet pipe, which prevents air from the cooling system. If desired, you can combine both methods.

The price of a cooling fan and the cost of replacing it

Prices for a cooling fan for the Lada Kalina (electric motor with impeller) vary between 1500-2500 rubles. Replacing this unit at a service station will cost 300-400 rubles.

When buying a new fan, pay attention to its manufacturer and catalog number. This part may have the following numbers:

• 1118-1308008;
• 1118-1300025;
• 21230-1300025-00;
• 2123-1300025 (with two engines for Kalina 2123);
• MOD285 (BM brand);
• BMMOD285 (Pilenga brand).
