Kalina 8 valve engine gets hot reasons

You should monitor the engine temperature

Despite the high-quality assembly, the engine of each car can be subject to severe overheating. Many factors can lead to this outcome, especially high air temperatures during hot periods of the year.

Spare parts of the car engine and components interacting with it may fail, even if the permissible engine temperature has increased for a short time. Such situations must be warned in time to avoid unnecessary financial costs for updating parts. This means that you must always monitor the engine and its cooling system, eliminating any problems that arise.

The reasons for engine overheating in domestic cars can be either external or internal. Internal overheating poses the greatest threat because it is more difficult to detect. In such a situation, the antifreeze maintains its operating temperature, because the heat is present only inside the engine. In this case, the performance of the engine is greatly reduced, since the high temperature burns out the piston rings. As a result, this can lead to complete destruction of the motor from the inside.

The importance of using antifreeze

Monitor the antifreeze level

External engine overheating can occur for a number of reasons, and one of the main ones is insufficient antifreeze in the cooling system. Antifreeze can leak out easily because it has the structure of a regular liquid. Therefore, it is necessary to constantly monitor the integrity of the hoses and their fastenings.

Try to pay attention to the surface where the car has been standing for a long time. Light spots on it indicate a coolant leak. If such signs are detected, it is necessary to urgently check the integrity of all elements of the cooling system. If antifreeze leaks into one of the engine cylinders or into the oil compartment, serious complications are quite possible.

If you do not use antifreeze, but fill the cooling system with distilled water, you should not use hard water, which contains a large amount of minerals and salts. You risk ruining even a new thermostat after only 3-4 thousand kilometers.

Insufficient coolant level

This is now unlikely, because many modern cars have antifreeze level sensors. However, such cases do occur (say, in cars of previous generations). Imagine - the antifreeze or antifreeze (maybe due to leaking radiators or pipes), the stove does not receive enough heated liquid, and it is practically cold, the fan is blowing, and the air is cold (it simply does not heat). You need to add coolant to the level ( read how to do this here ). Also, if radiators or pipes are leaking, then the leak must be eliminated.

It is worth noting that if the cooling compound leaks, “air plugs” may form, so even if you add antifreeze - antifreeze, you need to wait a while for the air to come out.

Causes of external overheating of the Kalina engine

Engine overheating can be caused by extremely low circulation of cold air inside the radiator. Most often this is due to the power supply to the ventilation system. In particular, the sensor that controls the speed of rotation of the blades fails. In this case, you need to check the degree of tension of the belt that connects the ventilation sensor and the crankshaft. If everything is in order with the belt drive, you need to pay attention to the level of contamination of the radiator and, if necessary, clean the unit. The above actions will be useless only if the radiator has completely outlived its useful life. In this case, the unit will need to be replaced with a new one.

Overheating can occur as a result of warping of the engine head seal or cylinder block lining. Other reasons: overheating or damage to the unit. If you do not contact a service station in time, there is a possibility of engine water hammer or crankshaft destruction.

The motor may overheat if the temperature sensor is faulty. Over time, sediment builds up in every cooling system, preventing the thermostat sensor from moving freely. Eventually it stops responding to the temperature level of the antifreeze inside the engine. In this case, the thermostat will circulate antifreeze through a small circuit, thereby reducing the cooling efficiency of the engine. This may not have any effect on the engine in the cold season, but in warmer weather the engine will overheat.

Another reason why the engine heats up may be excessive valve burnout. The fact is that the operation of the internal combustion engine is based on the principle of cyclical combustion of fuel, which passes processed gases through the hole in the exhaust valve. These gases have an elevated temperature, which affects the overall heating of the engine of domestic cars.

The Lada Kalina engine heats up very quickly when it is overloaded in certain situations. For example, a car is used as a means of towing another vehicle or trailer. In addition, during the warm season, many people go on vacation to mountainous areas. At high temperatures, lifting the vehicle will require increased torque, which is achieved at low speed. As a result, the cooling system reduces its efficiency and the engine overheats.

The same fate will befall a car that sits for a long time in a stuffy traffic jam in an urban environment. The air under the hood heats up, and the lack of movement eliminates the possibility of intensive circulation.

Cabin filter

Every car has a cabin filter. It is through it that heated air from the stove (or cold air from the air conditioner) enters the cabin. If there were no cabin filter, then debris and dust, and sometimes fat particles (products of oil evaporation, for example) from the engine compartment would fly into the cabin. If this filter hasn't been changed in years, then there is a good chance that it is simply clogged and needs to be replaced. Air simply cannot pass through a dirty filter into the cabin, so it is not surprising that the stove on the Kalina does not heat the air well.

Solving this problem is quite easy: you need to remove the cabin filter and install a new one. It is located under the hood of the car, at the top left (near the front passenger seat). It can be accessed with just one screwdriver, and the cabin filter itself is cheap (its price is about 200 rubles).

Why does the engine get hot from the inside?

The consequences of external engine overheating are not as serious as internal ones, since the temperature sensor on the dashboard will definitely report the problem. You saw that the arrow crossed the acceptable mark and took action. With overheating from the inside, everything is much more complicated; most often it leads to serious problems.

During vehicle operation, sediment accumulates in certain engine parts, resulting from the use of low-quality fuel or oil. For this reason, the engine is usually overhauled and cleaned after a certain mileage. The sediment collects mainly in the cylinder head. If the engine is not cleaned in time, the sediment will form a seal with poor thermal conductivity. In this case, the antifreeze circulation circuits are blocked, the coolant loses its effectiveness, and the thermostat fails. As a result, the engine heats up, although you don’t notice it.

Circuits blocked by sediment increase the likelihood of cooling coating cavitation. Cavitation is the process of damage to the metal shell of the engine, which most often becomes the cause of its detonation. Often mechanics may confuse cavitation with corrosion, but they are not the same thing.

The fundamental factor in internal engine overheating is burning out of the compartments in the cylinder block. In this case, a dense layer of deposits forms in the compartments, which creates the effect of thermal insulation. Typically, such problems arise in domestic cars with high mileage, that is, the engine begins to eat up more oil. As a result, the motor consumes only some of the resulting lubricant, and the rest forms seals. As the mileage increases, the engine overheats more and more, and the car owner does not even notice this, since the temperature indicator on the instrument panel is within the normal range.

One of the most destructive factors contributing to engine overheating is the regular use of additives. They often cause the formation of a dense metal-ceramic layer on the surface of the pistons. This coating has extremely low thermal conductivity. The presence of this factor alone already guarantees engine detonation.

Recommendations for motor maintenance

It's better to prevent problems in advance

So, Lada Kalina requires competent and timely maintenance of the engine cooling system. It is necessary to constantly monitor the functioning of the belt drive, thermostat, ventilation cooling system, radiator, and also fill in a sufficient amount of antifreeze. In summer, it is better not to use low-quality gasoline, especially on long trips. In urban environments, you need to take into account the density of traffic on the streets and the level of air temperature.

When choosing antifreeze, you must remember that you cannot mix coolant from 2 different manufacturers. This is fraught with rapid wear of elements in the cooling system with further destruction of its parts. To prevent this situation, you need to choose the right brand of antifreeze. But first of all, you will need to determine what kind of coolant is used in your Kalina.

Heater radiator is clogged

There may be several reasons:

The first is improper mixing of antifreeze and antifreeze . For example, in G13 you filled in, say, G11 or even antifreeze, then a sediment may appear that will quickly clog all the thin radiator pipes.

Secondly, they poured water. Water not only causes rusting of metals in the system, but also forms scale on the walls.

Third, they eliminated leaks in the heater radiator or main radiator using all kinds of sealants. On the one hand we heal, on the other we cripple. The passages in the radiator can become clogged with excess of this sealant; the liquid cannot circulate normally in it and, accordingly, heat it up, which means it will not really heat it. True, your engine may show high temperatures, at the limit level (the main thing is not to overheat it). You need to either flush the system, clean the radiator, or simply replace the radiator.

Reasons for engine heating

Cooling system assembly

Quite often you can come across the concept of engine overheating on the Lada Kalina. There are quite a few reasons and they are worth knowing if you want to carry out the repair yourself without resorting to the help of a car service.

The main reason why overheating occurs (4th error on the instrument panel) is a malfunction in the engine cooling system, as well as, in rare cases, accumulated errors in the engine control unit. So, let's look at the main reasons for overheating of the main power unit of the Lada Kalina:

Clogged engine cooling radiator and cooling lines.

Diagram of the working thermostat. If there is a malfunction, it jams into a small circle, causing the car to become very hot.

Coolant sensor locations

Cleaning the cooling radiator from debris

All these elements are part of the cooling system, which can fail.

Heats up at idle

At idle, the engine gets hot, most likely due to a faulty thermostat or a clogged radiator. Therefore, the reason must be sought here. First, you need to replace the thermostat. This operation is carried out quite easily:

Drain the coolant through the radiator drain plug.

The drain plug in the radiator is located at the bottom right

Thermostat disassembly diagram

Attention! The new thermostat comes with a gasket that must be installed. For normal manufacturers of spare parts, it is included with the part, so it is worth checking its presence in the box.

We carry out the assembly in the reverse order.
Fill in coolant.

Important! When replacing a thermostat, it is recommended to pour completely new fluid into the system, since the wedge of this element can be caused not only by wear of the part, but also by the loss of the physical and chemical properties of the coolant.

Pour coolant into the system through the expansion tank

We warm up the car to operating temperature and test whether the problem is resolved. If not, then you need to remove the cooling radiator, wash it and blow it out. Also, heating can be caused by insufficient liquid, so it’s worth looking to see if a pipe has burst somewhere or if liquid is leaking from the system.

Engine gets hot in traffic jams

A faulty cooling fan can cause your car to heat up in traffic jams. There may be several reasons for this:

Burnt out cooling fan.
Failure of the fan control relay.

Replacing the fan relay

Usually, it is in the wire connection block that the contact melts or oxidizes, which leads to an open circuit

Blown cooling fan fuse

Therefore, if the cooling fan does not turn on, you need to look for the reason here.

The second reason for the engine heating up in traffic jams may be a malfunction of the engine cooling thermostat. Replacing it is quite easy and simple, but it may take a lot of time.

Heats up to the red zone

When the engine heats up, when the arrow on the dashboard moves to the red zone, then the thermostat and engine temperature sensor are definitely faulty.

In this case, when the power unit heats up to 100 degrees Celsius, the cooling fan should turn on. If it does not turn on, then you should look for the reason in the fan circuit.

Heating the engine to the red zone

You should not allow the engine to overheat in the red zone, as this can lead to deformation of the cylinder head, gasket breakdown and failure of other elements of the main power units.

Recommendations

Some car enthusiasts recommend installing cooling system tuning kits. It has an increased service life, and due to the improved operation of the thermostat and high-speed pump, the car cools better, which prevents overheating even with frequent use of high speeds.

Installed tuning cooling kit

Device and features

The cooling system of the Priora internal combustion engine has a standard set of main components:

radiator;
thermostat;
electric fan;
water pump;
heater;
engine jacket;
connecting hoses;
expansion tank.

By circulating through the large and small circuits, the coolant prevents the engine from overheating, maintaining the desired temperature. Structurally, the cooling system of the Priora is simple and no different from other internal combustion engines with an injector, with the exception of small parts.

Radiator and forced cooling fan

They mainly serve to bring the working fluid to the optimal temperature for the functioning of the engine (the operating temperature of the Priora engine with 16 valves is 90–95 degrees). The predecessor of the Priora VAZ 2110 often installed a cooler made of copper alloys, but due to cheaper prices, designers switched to aluminum analogues.

The operation of the fan depends on the engine control unit.

It receives information from the DTOZH (this is a sensor that reads temperature readings) located in the water jacket of the power unit. If the permissible temperature values are exceeded, the control unit connects an electric fan to improve cooling efficiency. A faulty fan or clogged radiator can lead to a constant increase in optimal engine temperatures, which shortens the service life and can cause costly repairs.

Thermostat

Its task is to promptly open coolant access to a large circle of the engine cooling system (engine cooling system) after the engine reaches the optimal temperature. In simple terms, the thermostat allows you to quickly warm up the engine and regulates the operation of the entire system. During warming up, the thermostat valve is in the closed position, antifreeze does not flow through the large circuit (the radiator is not activated). As it warms up, the valve opens slightly under the influence of rising temperature, and antifreeze begins to move through the radiator along a larger circuit.

A thermostat malfunction can result in overheating of the power unit (if the valve is stuck closed) or, conversely, the operating temperature rises very slowly (when the valve is stuck in the open position). Overheating is much more dangerous. Beginners can identify this malfunction if the engine heats up all the time and the fan on the Priora is constantly running.

Pump (water pump) and heater

Without the first part, the coolant circulation circuit in the system is impossible. If the water pump is faulty, at best there will be a coolant leak from the system. In the worst case, the pump may jam, which will lead to a broken timing belt and subsequent problems, the solution of which will result in expensive repairs.

The heater, or simply the stove, consists of a radiator, pipes and a fan. Can additionally cool the antifreeze in the system. An indispensable unit in winter. Provides the interior with warm air.

Connecting elements and expansion tank

It serves as a receiving compartment where gases and vapors are discharged when the coolant is heated. Also, the expansion tank is the level for the entire cooling system. One of the main elements in the tank is the valve cover through which air is forced out. There is antifreeze, it begins to boil when the engine temperature rises critically.

The design of the cooling system also includes an engine temperature sensor on the Priora and an engine jacket. The sensor constantly reads information about the current antifreeze temperature and transmits it to the ECU. The location of the power plant jacket is structurally assumed in the cylinder block housing; it serves to remove heat through the coolant.

conclusions

The causes and methods of elimination, heating of the Lada Kalina engine in different modes are considered. So, the main reason remains the thermostat and radiator, which can fail. All other problems are purely individual and are determined through diagnostics and dismantling. You should not allow the engine to overheat, as this can adversely affect the operation of the power unit or cause it to fail.

I went to the garden after work. And water, and walk the cat for the first time.

It was +30, I was driving with air conditioning. The engine gets hot in traffic jams (it’s been like this since new - with a perfectly clean radiator - they say this happens on all vases). And then I remembered that I wanted to write one thing that everyone probably already knows, but suddenly.

During a trip to the Pamir Highway, on ascents, the engine temperature confidently crawled up to 100 degrees, sometimes higher. I fought this in a simple old-fashioned way: I turned the stove on full blast. The windows are open, so, to put it mildly, it’s not cold, but here you also get extra toasty.

Yes, it certainly brought down the temperature, but not as quickly as we would like. It would be more accurate to say that it didn’t just knock her down, but basically did not allow her to grow further. She lost her way very badly. And at some point a simple thought came to me: the car has air conditioning. There are two radiators, two fans... In general, I continued driving with air conditioning - on difficult sections I always turned it on. And the fan cooling the air conditioner radiator, in my opinion, is noticeably more powerful than usual. The first time it turned on, I even put down a few bricks. The engine temperature drops very quickly.

Yes, the air conditioner takes some power. But our ECU is smart. When you press the gas to the floor, it automatically turns off the air conditioning. This can be clearly heard by the click of the relay and the fact that the stuffiness begins again. You let go a little - another click of the relay, and again it blows cold air.

Almost every motorist has come across the concept of engine overheating, but not everyone knows why it occurs. Also, in this article we will talk about how to avoid this phenomenon, correct malfunctions and consider the recommendations of experts and the experience of motorists.

Hello forum members.

I need your help. I bought Kalina about a year ago and not long ago an unpleasant and intrusive knocking sound appeared in the engine. Before I drive it to the service center, where they clean out my pockets, I want to ask you. What could be the problem? A friend says that the problem may be related to the oil. I recommended Mobil oil. I use something else. Honestly, I didn’t even go into too much detail and took almost the first thing I came across. The budget is not rubber. and now I’m thinking, maybe I was greedy in vain? Is this the case when the stingy pays twice?? Has anyone used this oil? How is it?

Well, if it’s not the fault, then what?

conclusions

The car runs at idle and the temperature does not stay at 90, but starts to rise to 100, then the Carlson turns on and cools it a little. Then the same thing happens again. Is this a feature of Kalina Sport or what? Has anyone encountered this? Before this, my cars kept the temperature at a stable 90 and that’s it, but this one gets hot for some reason. Antifreeze is normal, it's not hot outside.

Stuttering when accelerating? Dig! — logbook Lada Kalina Sedan 2006 on DRIVE2

As you know, every car requires attention. So mine demanded it. Sluggish acceleration, vibration, consumption, shocks when switching. List of suspects:1. MAF sensor. I recently measured www.drive2.ru/l/477094589040165062/. The multimeter reading is 1.04 V.

According to the diagnostics, it showed 1.016 V. There is a third way - remove the chip from the mass air flow sensor and drive it. I haven't tried it.

2. Candles. I forgot to take a photo. Yesterday I took it off, like new. Candles cost 17 dv. www.drive2.ru/l/473344429755728085/. I'm going to install DENSO.

3. Air filter. Yesterday I took it out dirty. I blew it out from the compressor. I was breathing better. It was easier to go.

photo from the Internet. It looks like it was for me.

4. I have long wanted to try running antifreeze past the throttle valve. The fitting was used from an old radiator.

That's how I sawed it off.

did the same

5. Corrugation. www.drive2.ru/l/478326591819088066/. I've seen some cars come out inside. I thought so too. It turned out not. It just rattled and siphoned. Although sound could also play a role. After replacement the vibration went away.

Free passage

6. It remains to look at the injectors. There is no smell of gasoline. But the O-rings have already been purchased. I took washing for the injector and valves. I'll do it as soon as I fill the tank full. After this, you will need to replace the spark plugs as recommended.

Like this

7. Here I will simply post screenshots from the diagnostics. Guys who understand may notice. I'd be glad for your advice.
