Reasons for the increase in engine temperature on the Lada Kalina

Lada Kalina is equipped with an engine cooling system that prevents it from overheating. And this car has a standard ODS, no different from other devices of this type. This is a closed circulation of liquids from heating elements to the “point” of heat energy release. Many car owners are aware of the need to monitor the condition in which the car’s power unit is.

The cooling system is one of the main automotive systems of a car. And since it is so important, malfunctions in it are unacceptable. A properly functioning ODS is a necessity for the safe operation of any car, and the Lada Kalina is no exception. In a situation of system failure, overheating of the motor is inevitable. Extremely high temperatures can cause it to break. Besides, it's not safe. Not to mention the quality of work: it becomes less efficient.

For the reliable and efficient operation of the above-mentioned set of elements, it is required that they all act harmoniously.

Cooling system Lada Kalina: features

The operating temperature of the Kalina engine is up to 103°.

If the temperature is higher, the engine overheats, which means that the driver and his car will face serious troubles: head deflection or (even more depressingly) water hammer.

Overheating of the motor is possible in a situation where one or another cooling element fails. At first, a light phase begins - during which the engine begins to boil.

The consequences may be even more severe. They are characterized by deformation and deflection of the cylinder head. In this case, the situation can be corrected by simply grinding the surface of the latter.

The middle phase is characterized by deformation of engine parts of the same valve mechanism. In the future, the above-mentioned part will require serious repairs: after all, repairing the cylinder head is quite a financially expensive matter.

The heavy phase represents destruction from the strong heat flow of the piston group. Still, this defect is not the worst thing you can expect. But if coolant gets into the car cylinders, the power unit of your car will quite naturally suffer a water hammer. And then a major overhaul may not help.

How to check the sensor

DTOZH for Kalina has catalog article 23.3828; checking the element is mandatory if gasoline consumption increases and difficulties are observed when heating the engine. An enriched mixture will always flow into the cylinders, the radiator cooling fan will constantly work, which will lead to rapid wear.

If the element transmitting signals to the instrument panel fails, the indicator needle will stop moving and remain at zero.

Check the dismantled assembly with a multimeter by placing the element in a container (kettle, pan) with boiling water. As the liquid cools, the instrument readings will increase. How to check step by step:

1. Remove the unit from the car.
2. Set the multimeter to the ohmmeter position in the range of 100 Ohm–10 kOhm.
3. Connect the DTOZH outputs to the multimeter, lower it into boiling water, with the terminals located outside, only the head of the element is lowered into the boiling water, which in working condition comes into contact with the antifreeze or antifreeze in the system.
4. Check the table for the relationship between winding resistance and ambient temperature.

Checking the sensor that transmits temperature to the dashboard is carried out in the same way. The ohmmeter readings may differ from those indicated by 15–29 units.

Functional range of elements of a car cooling system

The standard cooling system consists of the following elements:

• sensors – determine t° in certain auto mechanisms; one of the management elements of the system;
• pump – makes it possible to circulate liquid in the SOD; operates in a forced mode;
• pipes – coolant moves through them;
• expansion tank - compensates for the volume of antifreeze, since due to temperature fluctuations it narrows and expands;
• radiator - a device that discharges excess heat into the environment;
• fan – activates the cooling process by forcing air; With its help, the cooling intensity increases;
• Thermostat - although small, is a very important element that regulates the amount of antifreeze; provides a “comfortable” temperature regime throughout the entire system.

Operating principle

The cooling system operates in a self-regulating mode, which is aimed at maintaining optimal temperature in the power unit. If the oil temperature rises significantly, the system does everything to ensure that the temperature inside the engine decreases.

Thus, with the close interaction of the above elements, the system functions. It automatically sets the necessary conditions for the inclusion and operation of structural parts, which ensures effective cooling of the power unit.

Possible malfunctions of the ODS, diagnostics

Almost always, a breakdown of the cooling function of a car is caused by an antifreeze leak. You should inspect the car under the hood for possible leaks. The cause of the leak may be:

• or a leaky clamp;
• or a radiator failure.

Then in the first case the element is replaced; this is not difficult and does not take long. As for the radiator, it is better to have it repaired. There are also no particular difficulties here: often you just need to solder the holes.

The reasons for overheating of this car can also be:

• thermostat. Its suitability is checked using both pipes: the temperature of the latter should not be sharply different (this is determined on a warm engine). Otherwise, the thermostat is faulty and antifreeze circulates in a small circle;
• clogging of radiator honeycombs. You can solve the problem by cleaning the outside of this element. Often this is not always easy to do, but there are no other methods other than manually cleaning the honeycombs;
• Fan malfunction. When the heating level of the coolant increases, this part should begin to operate. If this does not happen, check the relay, wiring or t° sensor;
• air in the coolant system. Lada Kalina is not insured, among other things, against the so-called air lock inside the system. In general, previous types of breakdowns are eliminated quite quickly and almost everything is clear with them. In the latter case, it is necessary to understand in more detail. The question - how to remove air from the Kalina cooling system - is really very important for the optimal functioning of the totality of the elements of this car.

Airlock

If the cooling system becomes airy, you need to do the following: with the expansion tank cap open, start the power unit, squeezing the gas pedal from time to time, warm it up until the t° sensor “reaches” the red scale. After “starting” the ventilation device, “add up the gas” a little more and then you can turn off the ignition.

If the cooling system is still leaking air and the above measures have not led to anything, you should act more radically. What needs to be done to remove air from the cooling system?

First, remove the power motor screen (dismantling is done in an upward direction).

Loosen the clamp with a screwdriver and remove one of the tubes from the heating fitting of the throttle assembly.

Unscrew the cap of the expansion tank. Cover the neck of the opened container with a clean piece of cloth. Now blow into the tank: coolant should flow from the tube that was removed. If you fail to break through the above container, close the lid and place the tube in its place.

Next, warm up the engine again and turn off the ignition. Then the tube must be removed again, without removing the lid from the tank, and wait until the antifreeze flows.

Since this liquid is very poisonous and dangerous for people, drain the coolant with extreme caution. Remember about safety: get rubber gloves. Monitor the temperature of the tubes. Keep in mind that you only need to drain the coolant when the engine has cooled down.

Now the tube is put on the fitting, the clamps are tightened. At this stage, the problem of how to remove air from the cooling system of the car has been successfully solved. As you can see, it is possible to eliminate faults in the ODS without the participation of professionals.

How to dismantle

Many drivers are confused where the temperature sensor is located in the system, which provides information to the ECU, and where the instrument cluster is. In Kalina, the first controller is embedded in the thermostat, which is located on the coolant outlet pipe from the engine. The transmitting sensor is located nearby; you can find it using a thin wire.

All work on removing and installing parts is carried out with the engine turned off and the negative terminal of the battery disconnected. Dismantling order step by step:

1. Loosen the screw securing the air hose coupling to the air filter housing. This will allow you to get to the instrument sensor. If necessary, remove the air filter housing for good access to the sensors.
2. Remove the screen or engine cover, using force, remove the cover from the latches.
3. Drain the coolant from the radiator. On Kalina, antifreeze or antifreeze is used. To do this, the fluid needs to be cooled, but experienced drivers replace it without draining the antifreeze. In this case, all replacement work will need to be carried out quickly and accurately. Therefore, if the sensor is changed for the first time, it is better to drain the coolant so that an air lock does not form in the system.
4. Disconnect the wire block.
5. Using a socket head or a 19 mm wrench, unscrew the sensor from its seat. If the coolant is not drained, antifreeze will flow out of the hole. Therefore, experienced drivers who are too lazy to drain it immediately clamp the hole with their finger and insert a new one.

Installation of the elements is carried out in the reverse order - the sensor is inserted into the hole, screwed in, connected to the wire block, and antifreeze is poured. The functionality of the system is checked after connecting the battery.
