Cooling system Kalina important points of improvement

Its structure and layout are quite typical for all cars, and are almost no different. The main purpose of this design is to ensure timely cooling of the main power unit and prevent it from overheating.

Cooling system diagram and operating principle

Engine cooling system diagram

So, many car owners are familiar with the main parts of the engine cooling system.

But, it’s still worth examining in more detail what is included in this simple design, which prevents the power unit from heating up:

Of course, in the cylinder block and head itself, there are also channels that serve as a cooler, where the liquid is heated. Let's consider the main stages of coolant recirculation through the system: from the radiator, through the line, the liquid enters the thermostat, which, depending on the temperature, releases the liquid in a small or large circle. Next, the liquid passes through the power unit, where it exits to the pump, which pushes it into the radiator.

Main problems and solutions

The main malfunctions associated with the cooling system include two parts that most often fail: the thermostat and the water pump ().

The first is characterized by jamming in a small circle, which leads to frequent turning on of the fan and possible overheating of the engine. In the second - wear of the pulley, as well as the shaft, which, when worn out, begin to leak fluid out.

Thus, drips from the pump may indicate that it is “on the verge” and needs to be replaced immediately. A sign that the thermostat is failing is when the fan turns on. If such factors occur, the part must be replaced. If the fan, on the contrary, does not turn on, then either the fuse has blown.

Consequences of untimely replacement of ODS elements

The consequences of untimely replacement of cooling system components on a car can be:

These are the main consequences that you should be wary of, so diagnostics and repair of the cooling system must be carried out every 20,000 km.

Tuning

Many car enthusiasts install sports kits on Kalina to improve the performance of the cooling system. So, they can be ordered in stores or purchased at car markets. What differences do they have from the standard ODS system:

• An additional pump with an electric drive is installed.
• The sports thermostat is made of cermet, so its service life is much longer than the standard one.
• The sports lines of the cooling system are made from a special material, which also allows for additional cooling.

The basic cost of a sports cooling kit for Kalina is about 20,000 rubles.

conclusions

The design and design of the cooling system of the Lada Kalina is not much different from its relatives from the rest of the VAZ family. This unit is quite easy to maintain and repair, which allows many motorists to carry out repair operations with their own hands.

Like many potassium growers, I was faced with the problem of airing the engine cooling system (ECS). The problem is especially acute in winter. I don’t see any point in explaining why this happens, because... You can find information about this on any forum; the cause of the airlock has long been determined by consumers; this is a design error in the development of the ODS. I will briefly describe the symptoms on my car: the temperature gauge shows 100-110 degrees and tends to the “red zone”, and cold air blows from the stove. The limit of patience was a long trip, when even at a speed of over 100 km and -20 outside the window, the engine temperature showed over 100! You can, of course, endlessly change the plugs on the expansion tank (RB) and the thermostat, however, this is how they do it at car services... however, it was decided to turn to network intelligence. Of the many improvements, I settled on the one suggested by driver vf013

The concept of the modification was completely taken from him and looking ahead I will say that this scheme works! Therefore, all technical questions that arise are covered on his page. Thank you vf013)))) So, for me the first problem was that none of the VAZ engineers drew a diagram of the ODS with an EPG (electronic gas pedal), the old diagram of a throttle unit (DU), which is heated by two hoses, is everywhere. rice. 1 Due to the abundance of “extra” hoses, it becomes difficult to understand what goes where and why...

Rice. 1. Old circuit with remote control, my car has EPG

. Therefore, I had to draw a new diagram with EPG (Fig. 2); of course, the e-gas itself is not present in the diagram, because it is excluded from the engine cooling process.

In Fig. 2 conventionally shows a hose that looped the system that previously heated the throttle assembly, in fact, I always had air collected in this appendix... so there is no place for it in the new system. I repeat once again that I did not come up with the modification scheme itself, but only changed the one proposed by vf013. Here's what I got. Rice. 3

Rice. 3 Basic modified scheme of SOD

For a better understanding, I immediately removed the “extra” hoses from the drawing, which were dismantled as a result of modifications. Results: several days have already passed, and the air temperature outside has risen and dropped from -2 to -10. I didn’t specifically post the results of the revision, because... I was afraid to jinx it)))). Immediately after launch, the system began to deflate, I will try to post a video of the process. When driving around the city, the engine temperature always stays in the operating zone of 90-95 degrees, while the stove begins to warm up with heat already from 50 degrees! It is clear that this slows down the process of warming up the engine itself, but a fact is a fact. All costs for modifications cost about 550 rubles, of this amount the most expensive is 1 liter of antifreeze for refilling, 1 m of hose for connecting to the RB, the rest is all small things - tees, clamps... I am satisfied with the modification and recommend it to anyone who has similar problems . Believe me, the mechanic at a car service center, when describing such symptoms, will say that your thermostat needs to be changed, because it is stuck and does not open to the Large Circle, so the temperature is high in the Small Circle, however, this is a dead end, because in my case the thermostat was working, it is easy to check if you want.

After purchasing a new Granta or Kalina 2, owners are faced with the unusual absence of an engine temperature indicator. There really aren't any on the updated models. Having carried out diagnostics, many are indignant at the reduced “operating” temperature of the engine (77-81 degrees). We hasten to please you - this is not a malfunction of the thermostat or cooling system. This is her “trick”.

The figure below shows the hydraulic diagram of the engine cooling system of the new Kalina.

Here the numbers indicate:

1. Cooling system radiator 2. Engine 3. Pump (water pump) 4. Pump supply pipe 5. Thermostat 2190-1306010 6. Interior heater radiator 7. Expansion tank.

Features of the new system

– a single-pass heater radiator, with reduced hydraulic resistance, brazed aluminum, with increased thermal efficiency, built in series into the “small circuit” of the cooling system, in contrast to the previously accepted parallel installation of a two-pass heater radiator;

– thermostat 2190-1306010 has one, not two valves and controls only the flow of coolant through the radiator of the cooling system;

– single-pass radiator of the cooling system with reduced hydraulic resistance.

All this made it possible to significantly increase the efficiency of the cooling system.

Spacious interior is one of the undeniable advantages of Granta

Thanks to the larger wheelbase, even a large person can easily get behind the wheel of the car, and the passenger does not have to squeeze into a limited space. Driving in a car is also more comfortable, because the plastic in the cabin does not creak or grumble, and sounds from outside are muffled by high-quality sound insulation.

If we compare what's best about the Grant Priora and the Kalina liftback, the Grant is miles ahead of its teammates in terms of cabin quietness. Otherwise, the liftback interior is not much different from the Kalina, and also has some absolutely identical elements.

As for the trunk, the Granta exceeds all expectations here. The volume of 440 liters, from 355 liters to the Kalina, allows you to transport a large number of things, so a comparison of the Grant liftback and the Kalina station wagon will definitely be in favor of the Grant.

Reasons for airing the cooling system

Beginners in the car repair business mostly turn to a car service when traffic jams occur. However, the verdict from service station workers is always the same - a complete replacement of the thermostat or a comprehensive repair of the part is necessary. How advisable this is is a big question that only another specialist can answer.

Why the cooling system may become faulty:

1. If there is a coolant leak, you will definitely notice marks on the outlet. Check the integrity of the clamps and radiator. It may be enough to replace or partially repair the device. Whether antifreeze is circulating or not can be determined by observing whether the liquid flows into the tank. If there is no circulation, be prepared to replace the pump or clean the cooling system with special cleaning solutions. It is better not to use water or cleaners that you use in the kitchen - the result is minimal, but it is quite possible to harm the machine.
2. The thermostat or its components have failed.
3. The honeycomb from the radiator is dirty.
4. The radiator is broken.
5. There are traffic jams in the system.

How to troubleshoot your cooling system yourself

If you notice that a stream of cold air is entering the cabin, you should not delay repairs, especially if the autumn-winter period is upon us.

Fixing improper cooling can be done in several ways. Car enthusiasts recommend following step-by-step instructions on the forums:

1. Remove the hose from the part responsible for heating the throttle assembly.
2. Open the expansion tank cap and place a clean, dry cloth on top of the neck.
3. Blow into the tank.
4. Monitor the progress of the antifreeze. As soon as the coolant appears on the horizon, quickly return the hose to its original place and tighten tightly with a clamp.

Why might this method be dangerous? Coolant is a toxic solution and must be handled with extreme care, so to prevent the substance from spilling, it is advisable to enlist the help of a friend who will help you quickly install the hose. In addition, antifreeze is hot and can burn your hand.

Another option for combating the airing of the cooling system in the Lada Kalina from folk craftsmen, it is more reliable:

1. Wait until the engine has completely cooled down. Remove the hose from the expansion tank. It is mounted close to the rest of the components of the Lada Kalina cooling system.
2. Pour liquid into the antifreeze reservoir to the maximum possible level and screw the cap tightly.
3. Place the hose in an empty container up to 5 l. Place a hose coming from the air pump unit onto the tank nozzle; the latter is intended for inflating Lada Kalina tires.
4. Use a pump to pump up the pressure in the tank, so that the coolant will move freely into the prepared canister.
5. Do not take your eyes off the reservoir, otherwise the liquid may overflow. If, on the contrary, it is not enough, antifreeze should be added to the required value.
6. When the liquid is completely added, put all existing connections back in their original places.

An important nuance - if clogging of the cooling system with a plug on the Lada Kalina occurs with enviable regularity, this means that the cooling system is far from ideal tightness. Therefore, check the connections and fit of the components to each other.

How to modify the cooling system of the Lada Kalina

Traditionally, modification of the cooling system on the Lada Kalina involves the installation of a new thermostat with 6 recesses, a filter through which antifreeze passes, and a faucet for the furnace mechanism. Service station workers also recommend installing another pump. This amount of work requires repair skills and knowledge. The average driver does not have them.

Therefore, craftsmen came up with another way to improve the cooling system. Follow the step by step instructions:

1. The cooling system should be looped with a hose that was previously used to warm up the throttle assembly.
2. Take an extra hose, a tee and enough clamps, and then install a connection with a smaller diameter. This will help ventilate the cooling system and bring it back to life.
3. It is preferable to place the air vent closer to the thermostat; a prepared tee will help with this. It should be cut into the supply hose to the radiator unit.
4. Now start processing the second end of the air outlet component, attach it to the steam outlet passing near the RB fitting.

The proposed modification to the cooling system of the Lada Kalina will make it possible to maintain the temperature when moving the car at a constant level of 90 to 95 degrees. At the start, the stove warms up to 50 degrees. How expensive is this method of improving a cooling system prone to air pollution? When purchasing the missing coolant, tees and clamps, 1 m of hose, 600 rubles were spent. Those who have already tried the modification note a noticeable decrease in engine temperature, but before that it heated up to 100 degrees, and cold air flowed into the cabin from the furnace mechanism.

The closed type is developed on the basis of forced circulation. The SOD consists of various elements, including the radiator, fan and thermostat. The system removes thermal energy from heated engine parts using antifreeze.

Traditional Troubleshooting Methods

To solve the problem of airing, you should open the expansion tank, start the engine, press the gas pedal several times until the sensor arrow reaches the red zone. If the fan turns on, you need to squeeze the gas all the way several times and turn off the ignition. If this method is ineffective, the following procedure is used. The plastic motor protection is removed, the clamp is lowered and one of the fitting tubes is dismantled. The expansion tank cap is opened and the system is purged until coolant begins to pour out of the removed tube.

A standard modification to the cooling system involves installing a new 6-hole thermostat, coolant filter and heater valve. To maximize coolant flow and minimize the risk of overheating, you will need to install an additional pump.

Design elements

The expansion tank of the Lada Kalina car is made of transparent polyethylene. The system in question is sealed due to the presence of inlet and outlet valves. The SOD scheme in Kalina provides for the presence of a coolant pump. The device body is made of aluminum. There is a control hole inside the unit, which can be used to detect fluid leakage if the pump breaks down.

The cooling system consists of 2 circulation circles:

• the liquid moves through the jacket and radiator (large circle);
• the liquid moves only along the jacket (small circle).

The SOD scheme provides for constant circulation of liquid. This does not take into account the position of the thermostat valves. The last device consists of 2 valves that redistribute the flow of coolant. When the engine is cold, the fluid circulates in a small circle.

Important points of improvement

Coolant is considered a toxic substance that adversely affects human health. Auto mechanics recommend draining antifreeze with caution. When carrying out this procedure, you need to remember safety precautions and use rubber gloves. The antifreeze is drained when the engine is cold. Then the tube is put on the fitting, the clamps are tightened. Air masses have been successfully removed from the system under consideration.

Self-tuning

Causes of Kalina engine overheating:

• thermostat failure. To check its performance, visually inspect the radiator pipes. If the top is cold and the bottom is warm, then the thermostat is stuck. In this case, you will need to install a new device;
• the honeycombs are clogged. In this case, the engine overheats in spring or summer. It is recommended to clean the radiator (from the outside);
• fan failure. The device does not start due to high coolant heating. It is recommended to check the functionality of the relay and wiring;
• air in the system. In this case, open the expansion tank. After starting the engine, periodically press the gas (until the red mark is reached). If the fan starts, then they “add up the gas” by first turning off the ignition. If the breakdown is not repaired, then the power unit screen is dismantled. First raise the motor and lower the clamp. One pipe is dismantled. The lid is removed and the container is broken through. The tube and cap are installed in place. The engine warms up and the ignition turns off. Then the heating tube is removed. Since antifreeze is a toxic substance, it is recommended to drain it carefully (following safety precautions). The engine must be cold. The tube is put on the fitting, the air is removed.

If the engine gets hot, the Lada Kalina SOD will be upgraded. Refinement of the system consists of installing a thermostat with 6 holes. The device is designed to maintain a stable fluid temperature and normalize the operation of interior heating devices. If necessary, install a coolant filter or heater tap. To quickly pass antifreeze through the channel (with minimal risk of overheating), an additional pump is installed.

The system under consideration is suitable for the C/O and N/O stove on the VAZ 2110. In the first case, it will be necessary to throttle the output from the SOD. In this case, the stove will only work at high speeds. In order for hot air to flow from the heating unit, press the gas pedal. If you reduce the output from the C/O stove, then the pressure in the remote control will rise. To do this, use a throttle or ball valve. Before installing Kalina SOD in a VAZ, it is recommended to consult with specialists.

To perform tuning yourself, it is first recommended to study the SOD diagram.

If you do not replace a failed thermostat, you should expect problems in the future. The replacement procedure is not complicated. By performing it in full compliance with the correct sequence, you can be sure of a positive result. And most importantly, replacing the thermostat on a Lada Kalina on your own will save a lot of money.

Grant stove radiator for viburnum

I welcome everyone to the vastness of Drive and our vast Motherland. Prepare your sleigh in the summer. Therefore, I decided to change the heater radiator. I’ll say right away that the heater radiator on this car is original from the factory; about two years ago it began to leak slightly. I poured in liquid American radiator sealant. At first it helped, but already this winter, when the stove was turned on, the smell of antifreeze was felt, and only when starting it in cold weather. After warming up the smell disappeared. Apparently, when expanding, the sealant still held on a little. I didn't add antifreeze too often. We can say that it is very rare. For my birthday, my brother gave me a heater radiator from Granta or from Datsun On Do, all aluminum. I have already studied this topic on installing such radiators on Drive. So I decided to install it today. In order for the radiator in the Kalinovskaya stove to work correctly, it is necessary to make an adapter-diffuser. I took the used front bumper from a scraper and cut out the necessary blanks from the license plate mounting area. I started adjusting and soldering the plastic parts. First I tried on everything in the body of a used stove from Kalina. I soldered a good adapter and secured everything tightly.

I thought I'd end it here. But they brought Mitenka’s shoes. To begin with, I decided to simply cut through the body of the stove, to make a groundwork, so to speak, and then, in another free time, install the radiator. Cut through. I wish I could calm down, but no, I decided to take everything apart further. I drained the antifreeze. He unscrewed the gas pedal. He pulled out the sawn-off part of the stove body. I started installing the radiator with the adapter assembly, but that was not the case. This dog doesn’t go there, and that’s all. Until the adapter broke, I didn’t calm down. It was already evening. We need to go. Think. In short, you need to solder the adapter, but not tightly, but leave it detachable in the part where the tubes come out. So I did. First I secured the adapter with one screw to the stove body. And after that I started installing the radiator. Again, I’ll say I had to sweat. After about half an hour, I finally put it in place. Then I used a soldering iron to grab the free wall to the stove body, after which assembly followed. In general, I started today at 12 noon and finished at 21 pm. No lunch. I poured in antifreeze, immediately turned on the stove, the temperature was still 60 degrees, but hot air was already coming from the stove. I hope there won't be any problems in winter. The sleigh is ready for winter. :). Thank you all for your attention. Be mutually polite and attentive on the roads of our country.
