The most important link in the cooling system of any car is the thermostat. Each mechanism is responsible for its functions. The thermostat in this case monitors the temperature regime of the entire system. In this article, we will consider the specified device in more detail, and also describe how to change the thermostat on Kalina.
Product Features
The essence of the mechanism of this device is that it opens and closes the valve through which the coolant moves. Thanks to this function, the engine is protected from overheating, and in the winter season, it is possible to save in fuel consumption and the time it takes to warm up the car. The Kalina thermostat starts to open at a temperature of 85 ° C, and is fully open when the arrow rises to 100 ° C.
Engine overheating
This concept is important to know in this case. What is an engine overheating and how is it dangerous? The answer to this question is simple and clear. Overheating is something that should be avoided, but occurs mainly due to a faulty thermostat. This is not to be forgotten.
Definition of a broken thermostat
This can be done according to some signs, which everyone should know:
- Significantly increased the time spent on warming up the engine. This is hard not to notice.
- Increased temperature and, as a result, overheating of the engine.
Diagnostic Methods
It’s best to control the situation and try to check the specified device as often as possible. The question immediately arises of how to check the Kalina thermostat. Experienced car owners and masters in car dealerships identify two main diagnostic methods:
- The essence of the first method is that the pipe is checked while the machine is running. This is easy to do. The pipe should remain cold after a couple of minutes of engine operation. From this we can conclude that if this part becomes warmer, it means that it has not completely closed, as a result of which there is a malfunction that needs to be fixed as soon as possible. You should also know that at a temperature of 85-90 ° C the pipe must reach a hot state. If this does not happen, then it is in a malfunctioning state.
- The second method is based on checking the operation of the thermostat at home. This is also a simple method. Here it is necessary to disconnect and get the Kalina thermostat. After this, it should be lowered into a container of water and put to boil. If the thermostat opens at high boiling point , then it is in order. If something went wrong, then you can safely replace it.
How to change the thermostat on "Kalina"? Required Tools and Process Description
If, nevertheless, a malfunction is detected, and a decision is made to independently change the indicated device, then for this process the following will be required:
- Thermostat "Kalina" itself;
- socket wrenches at 12, 13;
- sealant, it is desirable in this case to use silicone;
- a screwdriver in the form of a cross;
- container for coolant with a capacity of 5 liters.
With an independent replacement, and even if you do this for the first time, try to do the work in the following sequence:
1. Drain part of the coolant.
2. Remove the air filter. To do this, unscrew the two screws located in the upper part and the nut located on the side of the engine compartment. Find a recirculation valve on the filter housing. It also needs to be removed. All tubes inside the valve should be pushed to the side so that they do not interfere. After this, continue to work with the air sensor, in which you need to loosen the clamp and remove the air hose. Removing the air filter will require a little effort.
3. Next, loosen the clamps using an 8-wrench and a Phillips screwdriver. Then remove the four hoses. If the system was sufficiently pumped, then a lot of fluid will not come out.
4. Then unscrew the nut on the thermostat cover and disconnect the ground wire. In this paper, use the key at 12.
5. Remove the stud from the surface, and remove the nut from the bottom. By loosening and using force, try to get the thermostat. Here you will need a key at 13.
6. After all that has been done, be sure to clean the area of dirt accumulated there. Apply a layer of sealant to a clean and dry surface of the seat and apply a paper pad.
7. The sealant should crystallize, wait 5-10 minutes.
8. Then set the new thermostat, following the same path, only in the opposite direction. The main thing - do not forget to rearrange the temperature sensor, which was in the old mechanism.
9. Check that all hoses and fittings are connected correctly, and add the required amount of fluid.
10. Start the engine and inspect for leaks. If they are not there, then you did the job correctly, but if there is, then carefully check the entire mechanism and tighten the clamps.
After replacing the thermostat with Lada Kalina, you should start the car again. When it moves, it is necessary to control the temperature level. It should be around 90 ° C.
How to determine the best thermostat for Kalina
Before changing the specified device, it is necessary to solve the problem of its correct choice. When buying this product, the first thing you need to look at is what it is made of. After all, a poor and low-quality device can after some time simply become corroded, which will cause a lot of trouble. It is best to use a thermostat made of brass or stainless steel. The base of the case is the most important factor of choice.
Also, the question of how much the thermostat costs for Kalina can be answered quite simply. The price of the specified device is acceptable and everyone can afford it (from 300 to 430 rubles, depending on the brand of the manufacturer).
