Which thermostat is better to install on Kalina? Pay attention to the native one from AvtoVAZ

The thermostat is one of the most important elements of the cooling system of an internal combustion engine. It is designed to regulate the direction of movement of the coolant (coolant) depending on the degree of its heating.

When starting a cold engine, a working thermostat is closed, which forces the coolant to move in a small circle without passing through the cooling radiator. This is necessary so that the engine heats up faster.

When the coolant temperature reaches 85-90 degrees, the thermostat valve will open and antifreeze or antifreeze will flow into the radiator for cooling.

Choosing a thermostat

What is the best thermostat to install on Kalina? There are many options, but the most important thing is to know what this will lead to. Thus, a new thermostat of good quality will allow you to heat the engine up to 90°C, while old and outdated devices do not allow the scale to rise above 80°C. The new device will allow the Lada Kalina's engine to quickly heat up to operating condition even in thirty-degree frost.

If you can choose the right thermostat for Kalina, the heater will always heat up in winter, and the coolant temperature will be in the range of 88-95°C.

So, the best, according to most experts, is the device produced by Avto-VAZ. Yes, there are many defects among the products of this company, but we recommend installing a thermostat on Kalina from this domestic manufacturer. And the point is not even that your own shirt is closer to the body. No, everything is serious here.

The device from Avto-VAZ has a bolt specially placed to regulate the opening temperature. It is very convenient and everything can be adjusted manually. In addition, the device from this manufacturer is much more reliable than competitive products sold on the market today.

Replacing the pump on a Lada Kalina (8 valves)

On an 8-valve Kalina, you can change the water pump yourself. However, if the car owner does not have minimal experience in car maintenance, many questions may arise. For example, which pump to buy, how to choose the right tool, and is it worth draining the antifreeze from the system completely?

Which pump to choose

When the time comes to change the water pump, car owners begin to look at car dealerships for a worthy replacement. But which pump to choose so that it lasts as long as possible and does not cause problems for the owner?

In contrast, it will not last long - after 10 thousand kilometers the pump will need to be changed again.

At AVTOVAZ, designers install a TZA water pump on the Kalina. It has a long service life; drivers often change the pump only after 100 thousand kilometers. As an alternative, you can install more expensive German-made Bosch pumps - they are also famous for their quality and durability.

Where is the water pump located on Kalina?

Due to the fact that the pump is driven by the timing belt, it is part of the gas distribution mechanism. That is, you need to look for the water pump on the Lada Kalina from the side of the engine itself. Visually, before removing the belt, you can only see the pump pulley, which is involved in the gas distribution system.

The pump on the VAZ is located in the timing device

Preparing tools

It is recommended to prepare a standard set of tools for removing bolts and unscrewing nuts. You will also need a 6-point hex key. To drain the antifreeze without contamination and inconvenience, it is better to immediately find a container for draining and a rag to blot up any drops that have fallen on the engine elements. To ensure reliable installation of the pump, you can use a sealant with good thermal conductivity properties.

How much coolant to drain/fill when replacing the pump

In any case, before dismantling the old pump, you will need to drain the antifreeze from the system. This is necessary in order to reduce the pressure in the hoses and not be injured during sudden releases of liquid.

If the water pump has not been changed for a long time, then it is advisable to immediately drain the entire volume of antifreeze from the system and replace it with a new one. If the car owner has recently filled in new coolant, then there is no point in completely draining it: just disconnect the hoses from the expansion tank and wait until the antifreeze comes out.

To make it easier to fill a large volume of coolant, drivers usually use funnels

Operating procedure

First of all, you will need to install the machine on a flat surface. You can drive the Kalina into the inspection hole, you can simply lift the front right part on a jack. It is recommended to make sure that the car is securely secured; it is better to place additional supports under the body beam.

When dismantling the pump, you will need to remove the timing belts.

The work of replacing the pump on the Lada Kalina is carried out according to the following instructions:

1. Remove the engine splash guard.
2. Disconnect the negative terminal from the battery.
3. Unscrew the cap from the expansion tank and immediately remove the plug located on the cylinder block. Wait until the coolant drains out.
4. If all the antifreeze is drained, then unscrew the cap from the radiator and place a container under the drainage area.
5. After the antifreeze has been drained, screw all the plugs back on.
6. Remove the protective cover from the timing belt.
7. Loosen the belt by slightly tightening the timing pulley.
8. Remove the drive belt.
9. Remove the four bolts that secure the pump pulley to the cylinder block.
10. After removing the pulley, unscrew the last screws securing the pump.
11. Pull the water pump out of its socket along with the gasket.
12. Clean the planting site from adhering dirt and antifreeze drips.
13. Apply heat-resistant sealant to the edges of the hole and install a new gasket on it.
14. Place a new pump on the gasket and then proceed in the reverse order of removal.

What is it for?

As you know, this device regulates the temperature of the antifreeze, preventing overheating or underheating through a built-in valve. It is installed in the cooling system and automatically opens/closes depending on a certain situation. For example, if the liquid temperature is above normal, the valve opens and vice versa - if it is below normal, it closes.

In the second case

, the valve closes to reduce the warm-up time of the power unit in the cold season.

Closing the valve involves closing a large circle. As you know, the coolant moves in small and large circles. When the large circle is closed, the coolant flows through the small circle and after reaching 85°C the valve opens.

It is also worth noting that the thermostat is a completely mechanical device and the opening/closing of the valve occurs thanks to a special element, which is very sensitive. It is capable of melting when heated and opening the damper for non-stop movement of antifreeze in a large circle.

If for any reason this device does not work effectively, do the following:

• Purchase a thermal insert from Luzar;
• The air pipe is disconnected from the sensor. In addition, the connectors of the mass air flow sensor and the adsorber valve are removed;
• The air filter housing rises;
• The coolant is drained into some container;
• Remove the screws securing the thermostat cover clamps. They are removed;
• The device cover is removed along with the thermal insert;
• A new part is installed in your own garage (the approximate cost of a thermal insert is 140 rubles).
• After such modernization, Kalina will begin to warm up much faster, and the temperature will remain stable at around 90°C.

Verification methods

There are two ways to determine the functionality of the thermostat. The first method involves checking without dismantling. To do this, you need to start a cold engine, warm it up to operating temperature (about 90 degrees), and touch the lower radiator hose.

A cold lower pipe at this temperature indicates that for some reason the thermostat did not open. If it is hot, the thermostat operates normally.

For a more accurate check, you will need to remove the thermostat cover with the sensitive element. Place it in a metal container with clean cold water and place it on the stove to warm up. When the water temperature reaches 85-90 degrees, the element should operate, pushing the valve stem forward. If this does not happen, the thermostat is faulty.

How to check and replace?

Usually, it is possible to recognize a faulty device as soon as the following indicators are present:

• The engine takes too long to warm up;
• The coolant temperature rises unreasonably, and this causes the engine to overheat, even in the cold season.

Replacing the device with a new one is carried out as follows:

• First of all, the coolant is drained;
• The air filter is removed;
• Remove the hoses (there should be 4 of them);
• Unscrew the top nut of the thermostat and remove the ground wire;
• Now unscrew the nut on the device;
• Before installing a new thermostat, we prepare the seat. To do this, you need to clear everything of debris;
• Don’t forget to apply a layer of sealant or a new paper gasket;
• We install a new device.

How does the Lada Vesta engine cooling system work, what are the components?

• The pump is a CO pump;
• Engine radiator;
• Air conditioner heater radiator;
• Electric fan;
• Expansion tank;
• Thermostat;
• Connecting tubes.

Antifreeze is used to cool the engine. You need to use the same brand. And mixing liquids from different manufacturers is unacceptable. If the liquid runs out suddenly, you can add distilled water, but this should not be done in winter - it is better to constantly monitor the antifreeze level. As a rule, in winter, with the arrival of frost, the pipes begin to leak.

Thermostat functions and signs of malfunctions

The thermostat is one of the main components of the cooling system of any car; it is responsible for its optimal temperature conditions and preventing engine overheating.

A working thermostat can significantly reduce the time required to warm up the engine in winter.

The operation of the specified unit of the cooling system of the machine is carried out using 2 valves that operate automatically. The valves are opened using a heat-sensitive element, which, when the temperature in the system exceeds the normal temperature, begins to melt. The movement of coolant in the system is possible in a large or small circle. When the car engine warms up quickly, the large circle is blocked and the coolant flows through the small circle.

When the system temperature reaches 85°C, the valve partially opens and the liquid begins to move in a large circle. Its full opening occurs at a temperature of 100°C. When the coolant temperature drops, the valves close.

Various malfunctions in the thermostat can be identified by the following signs:

• the engine overheats and subsequently fails;
• a longer warm-up of the engine is required.

If you notice a malfunction in the thermostat, it is necessary to urgently replace it.

The owner decides which thermostat to install on his car. The following recommendations will help you make the right choice when purchasing this part:

1. The material used to make a high-quality thermostat is brass or stainless steel.
2. The thermostat for Kalina should be purchased from trusted manufacturers - AvtoVAZ, Luzar, Pramo, Elekton.

Many Lada Kalina owners ask the question, which is the best manufacturer of the main components of the car's cooling system.

All of the manufacturers listed above have proven themselves to be good. But the best for Kalina, according to most experts, is the domestically produced AvtoVAZ thermostat; it is reliable, durable, allowing the engine to quickly heat up to the desired state. This device has a bolt for manual heat regulation.

Checking for correct installation

It is very easy to check the correct installation and operation of the thermostat in the Lada Kalina. Here you will need to warm up the engine and then immediately turn it off. Next, open the hood and feel for the lower pipe that goes from the radiator to the cooling jacket of the engine block. If it is heated, the thermostat opens, and there is no risk of the Lada Kalina engine overheating. When this phenomenon does not occur, the system components require careful diagnosis. Therefore, it would be a good idea to check the functionality of the new thermostat before installation.

Annotation on replacing the thermostat on Lada Kalina

Replacing the thermostat on Kalina if it goes out of working order can simply be done by the driver himself. You should look more closely at the signs of a faulty thermostat, study the instructions for replacing it with a new device, and understand what tools are needed for this.

Instructions for replacing the unit

Before changing the thermostat on Kalina, it is necessary to carry out preparatory work, including the purchase of a new device and the selection of the necessary tools. For further work you will need:

• thermostat Lada Kalina;
• empty 5 liter canister;
• Screwdriver Set;
• silicone sealant;
• socket wrenches for 8, 12 and 13.

Now you can start doing the main work, having first installed the machine on the overpass. A complete replacement of the thermostat consists of a sequence of simple steps:

1. The coolant is drained into the prepared canister.
2. Remove the air filter by unscrewing the top bolts and nut, removing the connector, valve, and air hose from the housing, having first loosened the clamp.
3. 4 hoses are released; to do this, use an 8 socket wrench and a set of screwdrivers to release the clamps.
4. Unscrew the nut and stud using socket wrenches 12 and 13 and a screwdriver, remove the ground wire and the thermostat itself.
5. The seat for the new thermostat is being prepared: dust, dirt, and old materials are removed.
6. A thin layer of silicone sealant is applied to the seat, which is left for 10 minutes to crystallize.
7. A new thermostat is installed in the prepared place, and do not forget to replace the temperature sensor from the old device.
8. All steps to secure the new thermostat are performed in the reverse order: the ground wire is screwed in, 4 hoses are connected and coolant is poured into the system, do not allow air pockets to occur.
9. The correct installation of the device is inspected with the engine running; if necessary, the clamps are tightened to prevent leaks.

After replacing the thermostat on the Lada, you should carry out a control check.

When driving the car, monitor the current temperature level of the cooling system.

Correct installation of a new thermostat on Kalina should completely eliminate all signs of a malfunction in the car’s cooling system.

How to correctly determine that the device is in working condition?

We warm up the engine to such a temperature that the needle does not reach the critical value, and turn it off. We open the hood, find a hose on top of the radiator (a black rubber hose with a metal clamp at the end) and the same one on the bottom. Then, very carefully, they may be quite hot, touch them. If one of them becomes hot, and the other is still cold, and the sensor shows a high engine temperature, this means that most likely the liquid does not enter the engine, but is retained in the radiator, and you need to change the thermostat to a new one.

There is another way of checking, better known as “folk”. It echoes the “experiment” that was described above, to observe the process of the thermostat, only this time you will have to put the thermostat, the functionality of which you doubt, removed from your car, into a container with water, and then the procedure is repeated as Once the water reaches a temperature of 87–90 degrees, the valve should open, however, if this does not happen, then the thermostat is no longer suitable for operation. It is also worth remembering that different thermostats may have different critical valve opening temperatures, so when purchasing a new one, check this with the seller. Since it is no secret to the driver that it is impossible to install a thermostat in a car that has a high valve opening temperature - the engine will not cool.

Video, checking the thermostat VAZ 2101-2107 and Tama (Toyota):

This device is, indeed, not an expensive part, and its cost depends on the brand of your car. The price of a thermostat for VAZ 2101, 2108, 2110 and 2121 is approximately 230 rubles. A thermostat in a housing will cost approximately 400–550 rubles or more, but for a Lada Granta 8V car you can buy it for 1,200 rubles. For foreign cars - on average from 550 to several thousand rubles. The most common, popular and high-quality thermostats are GATES and WAHLER brands. There are also positive reviews about the manufacturer Vernet.

A thermostat is a device that regulates the temperature of the fluid in the engine cooling system. In its standard version, it is 5 cm in diameter and is located between the engine and the radiator. The operation of the thermostat allows you to maintain a constant temperature of the motor due to thermostats or due to the implementation of a phase transition.

The device blocks the radiator from coolant, thereby allowing the engine to warm up. In addition, this inherently simple mechanism reduces wear on the car engine. The device is closed if the engine temperature is normal, but as soon as it reaches a critical level of 90-95 ° C, the damper in the thermostat opens, which allows coolant to enter the engine.

Fuel pump: design features

Carburetor cars had mechanical pumps. The drive or dam pushed the diaphragm, in the process a vacuum was created and fuel entered the carburetor. Nowadays, almost all cars have an injection engine and an electric pump. It delivers hot food at high speed and maintains stable pressure in the system. The electric motor, together with the working rotor, pushes the fuel. The pump is located in the gasoline tank itself. During operation, fuel becomes coolant and lubricant. There are car models that have two pumps: the main one is under the hood, the worker is located in the fuel tank.

• special motor shell;
• heat exchanger with electric fan;
• device for maintaining a constant temperature;
• suction device;
• expansion tank;
• contact tubes.

By looking into the plastic expansion tank, you can visually check the amount of antifreeze and antifreeze. There are special marks for high and low levels of liquids in the tank. Outside the tank, there is a pipe at the top for connecting to the heat exchanger sleeve, at the bottom - to the filling tube.

• Expansion cap with breathers. The device includes inlet and outlet breathers. They are capable of providing systemic impermeability. The intake valve maintains elevated pressure in the hot engine. As the temperature rises, steam leakage decreases. The reduced pressure promotes the opening of the released breather as the car engine gradually cools.
• The pump pumping antifreeze is a blade of rapid discharge. The crankshaft wheel drives the pump through a toothed belt on the timing rod. Its body consists of aluminum. The shaft rotates in a double-row ball bearing, which contains enough fuel oil for the entire warranty period. The outer ring is tightened with a self-tapping screw. The gear is pressed in at the front, the impeller, retaining ring, and oil seal are at the rear. Antifreeze or antifreeze leakage is monitored through a hole in the pump shell. This method will help identify unit malfunctions. If the pump cannot be repaired, it is replaced with an identical assembly device. The coolant corrects the redistribution of antifreeze. System cooling of paired cycles occurs as follows:
• in a larger circulation circle, antifreeze penetrates through the engine shell to the radiator battery;
• when moving in a small circle, antifreeze or antifreeze passes only through the cooling shell, without getting into the heat sink.

The cooling system consists of a radiator battery and a throttle heating unit. The circulation of antifreeze or antifreeze here occurs continuously, regardless of the location of the coolant valve.

Thermostat. The thermal unit and two breathers are components. There is a redistribution of the flow of antifreeze or antifreeze. When the engine is cold, the node valve redistributes the direction of fluid movement. It begins to circulate over a smaller radius, without entering the radiator. High temperatures of 85°C allow the valves to open and allow fluid to flow into the radiator. At temperatures above 100° C, the main valve is fully open, the spare valve closes. Liquid circulation occurs over a large radius. Antifreeze or antifreeze temperature meter. This device is screwed into the cylinder head for automatic control of coolant. The sensor is connected to the temperature indicator on the instrument panel of the car. This information is sent to the controller. Heating heat sink. Built into the engine cooling system, it heats the vehicle interior by circulating hot coolant. The radiator consists of 2 plastic tanks in a vertical position. One of them has a partition. There are 2 more rows of rounded aluminum tubes, aligned horizontally, that pass through the cooling plates. The pipes are connected to the tanks through a rubber key. Antifreeze enters through the upper pipe and exits through the lower pipe. The inlet pipe is located next to a thin steam exhaust hose. The radiator has a casing with an electric motor. Drain plug at the bottom. The fan maintains the temperature inside the car. As soon as the controller receives the signal, the fan is turned on via a relay.
