Replacing the expansion tank Lada Kalina - step-by-step instructions

Refining the expansion tank cap on Kalina will help improve the cooling system. It is no secret that the normal functioning of the main components of the car depends on proper engine cooling. If the tank element in question does not perform its function correctly, pressure interruptions occur in the cooling system. Due to untimely bleeding of excess air, the pipes begin to leak. The hotter the power unit heats up, the higher the coolant temperature. Excess pressure from the sealed unit must exit through the expansion block and two-way valve.

After the system cools down, a similar process occurs, only with air being sucked inside. The tank cap should be periodically checked for scale, other formations and valve operation. If there is an excessive amount of various contaminants, the valve is deformed, does not perform its function and the system depressurizes.

Problems due to a faulty lid

Modifying the expansion tank cap on Kalina allows you to avoid malfunctions of the valve and freezing of the element in winter. Before considering options for modifying a part, you will need to find out the consequences of its malfunctions and how to check it.

Severe clogging of the expansion tank valve leads to pressure buildup, leakage of pipes, depressurization of the system and the formation of air locks. All this affects the operation of the stove and cooling unit. Due to such fluctuations, breakdowns of the pump, thermostat and connecting elements occur.

The functionality of the lid valve can be checked as follows:

• Visually inspect for the presence of rust and other foreign deposits;
• When mechanically pressed, the valve characteristically whistles, signaling the release of air, and after releasing, the norm is to hear a hissing suction sound;
• To check the system for blockage, you need to remove the hose from the upper fitting and connect it to the pump or compressor;
• The injection of the air mixture on the pressure gauge readings should correspond to values ​​from 1.1 to 1.5 kgf/sq.cm.

The final adjustment of the pressure will be made possible by upgrading the cover, which involves cutting off the thick spring of the part and adjusting it to the required air pressure.

Who has more choice of engines and gearboxes?

Since 2011, the powertrain models are almost identical. Both are equipped with 1.6-liter engines producing 87, 98, 106 horsepower. The difference in the amount of “horsepower” under the hood is achieved by modifying the engines and timing. But the Granta in the Sport package has a special 16-valve unit with 118 hp. Together with.

As for gearboxes, the sons of AvtoVAZ have two – 5 manual transmissions (modernized, cable type) and 4 automatic transmissions from Jatco. True, in 2018 Granta also received the Robotic 5 gearbox. And soon after Kalina 2, it also inherited the “robot”.

The first method of modernization

You can improve the expansion tank cap on the Lada Kalina using the method presented below. It is necessary to purchase a FEBI cover (02269)

. The price of the issue will be no more than 150 rubles. The standard Kalina cover should be disassembled and the valve mechanism removed from it. A similar procedure is carried out with the purchased part.

The original valve assembly is sawed down and removed along with the bead that helps center the spring. The Faby valve needs to be ground off no more than one millimeter. This manipulation will allow you to put him in a new place without any problems. The new valve is installed on the standard cover along with a rubber gasket. The part is screwed onto the neck of the expansion tank. The result is a frost-free lid, the production of which took no more than half an hour and quite reasonable financial costs.

Comparative characteristics

From the above we can draw the following conclusion:

• the grant has a modern platform and greater manageability;
• Granta is cheaper than Kalina;
• Granta top quality paint. Less susceptible to corrosion, retains its natural color longer.
• Compared to Kalina, Granta has better sound insulation, which allows you to talk in the car even at high speed.
• due to the safety and quality of the Grant, it simplifies the blocking of headlights and other parts of the body, but at the same time reduces the price of the car;

Some parameters are worth considering in more detail and comparing.

1. Appearance of the car. A quick examination of the new product may seem that Granta is not like other Russian cars. Upon closer inspection, we notice that the side doors are the same as those of the Lada Kalina. Moreover, the sedan bodies of both models are not much different. Grant is recognized only by its larger size and different shape of the bumper and headlights.
2. Luggage compartment. As for the trunk, the Lada Kalina remains on the bench. Due to the fact that Granta's body is longer than Kalina's, her torso is much larger. This is just a view of the “lame” trunk, and this is not the first time it has closed. But the size of the trunk speaks louder than its shortcomings, and that's good news.
3. Overview of the living room. Kalina users often received complaints about the unbearable creaking of panels, a large number of gaps and backlashes. In the new Lada Granta, these shortcomings have been corrected and the interior makes virtually no unnecessary unpleasant sounds. But the question regarding the plastic of the car is: is it cheap? Despite this, the Lada Grant salon has its advantages:

• nice and pleasant dashboard;
• cup holders installed;
• oversized glove compartment;
• No problems were found in the operation of the heating element.

1. Rack. A significant advantage of the Grant over the Kalina is the shortened steering rack. This decision was achieved thanks to the ease of driving of the new car. But there was no place in the car for an ashtray, but all was not lost.
2. Power supply. The engines in both cars are almost the same, but the subsidies have some advantages. With the same number of valves per cylinder, the Kalina engine is capable of developing 82 horsepower, and the Granta - 90. Such figures can be explained by the fact that the latter has a lightweight connecting rod-piston assembly. The Granta's power unit works faster than the Kalina and there is no additional noise.
3. Safety system. It is worth noting that the Granta has two airbags, which cannot be said about the Kalina, and this is a good indicator, considering the new product as a budget car.

In addition, the new product, like its competitor Lada Kalina, will exist in a sedan body. The Grant sedan looks younger, but the Lada Kalina is more functional in terms of transporting large loads.

The classic way to improve

To improve the expansion tank cap in this way, it is necessary to remove and disassemble the element under study. In this case, remove the rubber gasket and remove the inner part using a screwdriver or other suitable tool. The lid device itself consists of a housing, a pair of springs and a valve mechanism.

The essence of modifying the part is to trim both springs. The first element is shortened by 1 turn, the second copy by 2. After assembling in the reverse order, you need to check the efficiency of the modernized unit. As a result, the outlet part of the valve will open at a load of 1 bar (it is worth noting that the initial value was 1.7 bar.

).

Correctly performed modification will allow you to blow the lid freely with your mouth on the air inlet and outlet. If the process occurs without difficulty, it means that the part has been improved in terms of preventing the formation of air in the system and the flow of coolant through minimal gaps.

You can modernize the cover of the unit in question yourself, quickly, at minimal cost. The problem occurs not only on the car model in question, but also on other vehicles with similar characteristics.

Refinement of the expansion tank cap on Kalina significantly increases the working life of the cooling system and associated elements. In addition, the modification promotes normal operation of the valve in both modes and prevents freezing of the unit, even in severe frosts.

When the engine cools down, air is supplied through the steam exhaust hose from the expansion tank, this happens mainly in winter. And when the engine is started, air bubbles in the radiator of the stove and the heater does not heat well. The boiling on the stove got a little annoying, so I decided to get rid of it using a water seal on the steam exhaust hose. If in doubt, you can also read here www.lkforum.ru/showpost.p...?p=1158931&postcount=1455 here is also www.lkforum.ru/showpost.php?p=1256887&postcount=2

I took a bolt, cut off the threaded part as much as I needed, drilled it not straight through, and drilled it from the side.

We welded it with tubes (stainless steel), one long tube and one short.

I screwed a nut onto it and painted it for appearance.))

Now the expansion tank: I cut off the plug where the steam exhaust hose from the radiator is connected.

There is no need to drill anything, we cut the thread with an M12*1.75 tap.

And we tighten the water seal so that it does not let through, and we wind the fumka.

Now, instead of air, antifreeze is sucked in through a long tube and air does not enter the cooling system. —We drain the old antifreeze: We unscrew the cap on the radiator in the lower right corner, then open the cap of the expansion tank, and also unscrew the cap on the cylinder block, take out the top radiator hose of the interior heater and blow into it to expel the remaining liquid from the heater radiator. — We rinse: I tightened the cap on the radiator and began to pour distilled water into the cylinder block for flushing, when water came out of the heater hose, I put it in place and tightened it. We started the engine to run for a while so that a large circle opened and drove distilled water through the system (rinse) then I drained everything. — Fill in new antifreeze: Fill in the antifreeze in the same sequence as distilled water. We drive all the air out by placing the car on a hill in front and the left side of the car should be higher, and press on the gas until a large circle opens, it’s somewhere around 102-105 * C. This is the temperature when The thermostat is fully open and antifreeze begins to circulate through the radiator and expansion tank. We look at all the leaks, if there are any, we eliminate them (tighten the clamps). The water seal tube should not be long, it should reach the maximum mark on the expansion barrel, that is, it should be immersed in the coolant by 5-10 millimeters; if it is long, the system cannot expel air through it. I can’t promise that it will work for everyone, but if you do everything correctly, it will work. For me, it circulates through the water seal when the large circle opens. I’m happy as an elephant, the stove heats up perfectly. Thank you for visiting this page.

Self-tuning

Causes of Kalina engine overheating:

• Thermostat malfunction. To ensure their functionality, visually inspect the radiator hoses. If the top is cold and the bottom is hot, the thermostat is locked. In this case, you will need to install a new device;
• clogged honeycombs. In this case, the engine overheats in spring or summer. It is advisable to clean the radiator (external);
• fan failure. The device does not start due to strong heating of the coolant. It is advisable 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 throttle (to the red mark). If the fan starts, they "ignite with gas" after the ignition is turned off. If the malfunction is not resolved, the power unit screen is removed. First raise the motor, lower the vice. The pipe has been removed. The lid has been removed and the container has been broken. The tube and cap have been replaced. The engine warms up and the ignition turns off. Then remove the heating pipe. Since antifreeze is a toxic substance, it is recommended to drain it thoroughly (following safety precautions). The engine must be cold. A pipe is put on the fitting and air is removed.

If the engine warms up, the Lada Kalina SOD will be updated. Modification of the system consists of installing a 6-hole thermostat. The device is designed to maintain a stable fluid temperature and normalize the operation of heating devices inside the car. 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 short-circuit and open-circuit stoves on a VAZ 2110. In the first case, it will be necessary to throttle the output from the SOD. In this case, the oven will only operate at high speeds. To get hot air from the heating unit, press the gas pedal. If you reduce the heater C/O power, the pressure in the remote control will increase. To do this, use a throttle valve or ball valve. Before installing Kalina SOD in a VAZ, it is recommended to consult with specialists.

To configure it yourself, it is recommended to first study the ODS diagram.

up to 85 degrees, on average it’s always in this position; in summer in traffic jams it’s 90 – 91 degrees, which is quite comfortable. Turning the fan on controls the ECU logic, and the thermostat has almost no effect here - unless it's stuck. In general, the Grantovskaya SOD is very durable and compact in terms of the thermostat itself, after two years of use there are only positive emotions. He himself is not difficult, in any case, he changed it on his knees in the fresh air in the hot season himself

Symptoms of problems

There are a number of symptoms that indicate a malfunction of the cooling system; if at least one of them is detected, it is worth taking corrective action.

1. When the engine is not started and has cooled down (more than 8 hours of inactivity), a residual pressure remains in the cooling lines (this can be understood when the rubber pipes are pressed, they will be hard).
2. The release of coolant when the engine is running can be either a small amount or a significant column of steam.
3. Coolant leakage from lines or radiators is accompanied by a decrease in the coolant level in the tank.
4. When the engine is fully warmed up, cold air blows from the deflectors coming from the cabin heater. The effect may disappear when the crankshaft speed increases.

And if with the first three points everything is more or less clear, then with the last it’s not so simple. You can change radiators, thermostats and coolant as much as you like, but you still won’t achieve a positive result. The problem is the formation of an air lock that cannot be seen. The air in the lines prevents the normal removal of heat from highly heated parts, which can lead to serious damage to the power plant.

Tools

The following tools will be needed for work:

• Set of keys (including wrench, extension and sockets);
• Container for draining coolant;
• Hose;
• Syringe;
• Double sided tape.

As for the tank itself, it is recommended to buy a product of a new design - this is a reinforced tank, which can be purchased under article number 11180-1311010-10. Its price is low and does not exceed 300 rubles.

Refinement of the cooling system of the Lada Kalina car

Considering the fact that this problem is not uncommon for Kalina owners, we can assume that this is a miscalculation of Tolyatti engineers. The owner will have to correct this development inaccuracy.

1. Drain the coolant.
2. We dismantle and install the plug on the wide pipe, which is connected to the bottom of the expansion tank.
3. We install a tee in the lower hose of the stove.
4. We install a hose of suitable size, which is connected at one end to the tee, and at the other to the bottom of the expansion tank.
5. We install a plug in the return line of the throttle valve heating, and in its place we install an additional hose.
6. In the upper part of the expansion tank, you need to install an additional fitting, to which you need to attach a pipe for heating the throttle valve. There is also an option that does not require cutting in an additional fitting. To do this, you need to connect the new line to the upper pipe of the expansion tank using a tee.
7. Fill the coolant a little above the maximum mark, start the engine and warm it up until the fan turns on.
8. We expel air from the system, pushing through all the lines, and, if necessary, add coolant to the level.

This modification option will prevent the formation of an air lock, and if air gets in during scheduled repairs, removing it will not be difficult. After such a modernization, a slight negative effect is possible in the form of a long warm-up of the engine. But the undoubted advantages will be a well-heating stove and the absence of air locks.

Specifications

They look like Granta and Kalina. The cars are equipped with almost identical engines. The car can be equipped with a 1.6-liter engine with 87, 98 and 102 hp. An eight-valve engine with a volume of 1.6 liters and a power of 81 hp was installed only on the Lada Granta.

Exterior view of engine 21116 on Grant

All powertrains of these cars can be combined with a five-speed manual transmission and a Japanese automatic transmission. The chassis of the cars is also similar.

The only difference is in the settings, depending on the characteristics of a particular model.

Body

Video of how both of these cars are painted at the factory:

you need to start comparing these two body style cars. Today Kalina is offered in station wagon and hatchback body styles.

Appearance of Lada Granta

The subsidy applies only to the sedan body. Some car enthusiasts prefer to buy sedans for their classic looks and practicality, while some prefer sedans for their efficiency and compactness.

Kalina in the estate

Station wagons are chosen by those who value a large amount of usable space in the cabin.

We take potatoes from the dacha (photo by comrade Grantovod especially for the site)

It is worth noting that those expecting a spacious trunk from Kalina will be a little disappointed. Its volume is 360 liters versus 400 for Grant. The sedan has even less trunk space: 260 liters.

Equipment

The difference between Kalina and Granta becomes obvious if you look at the car’s equipment. The basic version is already installed in Kalina:

1. Electric power steering.
2. Short stance.
3. 14-inch wheels.
4. Cabin air filter.
5. Electric windows at the front.
6. Athermic glasses.

It should also be noted that Granta in its most expensive configuration is better equipped than Kalina, and at the same time the cost of the cars is almost the same. So, Grant can be equipped with:

1. Electric rear view mirrors.
2. Fog lights.
3. Heated rear view mirrors.
4. Electric windows on all doors.

Replacing the thermostat on Kalina 8 valves

The thermostat on Kalina consists of 2 parts - the so-called thermostat cover and housing. The cover is the part in which the thermocouple is located, and the housing is the part that is attached to the engine. Housings are not sold separately, unlike covers, at least I haven’t seen them. Therefore, you can either replace the cover or buy a completely assembled thermostat.

It is attached to the engine with 2 nuts along with the ground wire from the battery. We unscrew them and remove the thermostat. In most cases, the remaining gasket will stick to the engine. They will need to be removed with a knife or blade.

The coolant temperature sensor is screwed into the thermostat housing. You need to unscrew it from the old one and screw it into the new thermostat, or just buy a new one. It is attached under a copper gasket, which seems to need to be replaced with a new one, but practice shows that a used one also holds up normally. The thread of the sensor itself, closer to the gasket, can be lightly coated with sealant.

To be sure, I additionally applied a thin layer of sealant to the new thermostat gasket and installed it in the prepared place. According to reviews on the Internet, it is best to buy an original thermostat from AvtoVAZ. He will last the longest. In second place, this is exactly what I bought, since I simply couldn’t find the original one. Some samples may open not at 85 degrees, but at 90-95º. Not sure if this is normal. It should also be noted that the PRAMO thermostat cover will not fit into the AvtoVAZ body; the side will interfere, which the craftsmen successfully saw off with a grinder.

Replacing the pipes of the Kalina cooling system can be divided into replacing the heater pipes and replacing the radiator pipes. There are 2 pipes suitable for the stove - inlet (1) and outlet (2). There is also an inlet (3) and outlet (4) to the radiator. There is also a small connecting pipe (5) from the thermostat to the siphon.
