Replacing the thermostat on the "Kalina" with their own hands. Replacement of the thermostat at VAZ

Unfortunately, the cooling system of "Lada-Kalina" is far from perfect. Here, the most common problems are the flow of the radiator of the stove, the suction of air from outside, and the non-working thermostat. The latter can become a serious problem for the owner of the machine, therefore, in the event of such a problem, an urgent replacement of the thermostat at Kalina is necessary.

Thermostat operation

In the car cooling system, one of the most important parts is the thermostat related to the machine assembly. Thanks to this simple device of small size, the system keeps the correct coolant temperature at all times. And it still keeps the engine running.

This temperature-sensitive device is necessary in the car to prevent engine overheating, as well as to monitor the temperature of the coolant. This is done using two valves that are in the system. When the temperature becomes higher than normal, they automatically open. And vice versa, when it decreases - the valves are closed. It is very good in cold weather to shorten the time for warming up the motor. The movement of the liquid can be carried out both over a large and a small circle.

In order to quickly warm up the engine, it goes around a small circle, while the big one is blocked. It opens only when the temperature of the coolant reaches eighty-five degrees, and is completely unblocked only at one hundred degrees.

This is a completely mechanical device that works only according to the laws of physics. The process of opening the thermostat valve passes through a solid thermosensitive element. When heated, it melts, and as a result, a damper opens to allow the coolant to move freely along a large circle.

Symptoms of a thermostat malfunction

The first thing that should alert the car owner is a lot of time spent on warming up the engine. However, the most dangerous situation is its overheating or an increase in the temperature of the coolant without a base.

Such a case entails major problems, and a major overhaul of the engine becomes inevitable due to a decrease in its power.

If you notice the above signs, then the replacement of the VAZ thermostat is urgently required.

A sign of the health of the device in the car

In order to check the thermostat (it must be in the closed position, and the pipe that connects it to the radiator must be cold), it is necessary to start the motor. If this element is warm, it means not very tight closing of the described part, but because of this the motor heats up longer, which entails a higher fuel consumption.

Replacement of the engine thermostat is necessary if the nozzle does not become hot when the coolant is heated to ninety degrees centigrade.

Check of the removed thermostat

In dishes filled with water, you need to put the removed thermostat so that it does not touch the walls, and put it on the stove. Having included it, it is necessary to closely monitor the operation of the device. As the water warms up, the thermostat should gradually open. Before the liquid begins to boil, the maximum opening occurs.

After this, the device must be removed and monitored for the process of blocking it. As it cools down, it should close and get the original look.

In the event that during this test you have found any deviations, the thermostat must be replaced. "Kalina" 8-valve, like any other car, must necessarily be cooled down for carrying out this procedure. This is the most important rule that must be observed before starting work.

Replacement of thermostat

Before proceeding with this process, you need to prepare the following tools: the actual thermostat, the screwdriver set, the five-liter container in order to drain the coolant, the silicone sealant. It takes a couple of hours of free time.

Replacement of the thermostat on the "Kalina" can only be carried out by the driver himself. To do this, you must first install the machine on the flyover or observation pit, and then drain the coolant. After that you need to remove the air filter. To do this, unscrew the nut and the two upper bolts. Then it is necessary to remove the connector from the valve located on the filter housing, and then, pulling the valve up, remove it.

Now you need to remove the connector from the air sensor, and then the air hose, after loosening the clamp. After that, the air filter housing must be removed.

Slightly letting go of the clamps using a screwdriver and a socket wrench to eight, you need to remove the four valves. A good amount of coolant should be indicative of good pumping of the system, which will result from it.

Then remove the mass wire by unscrewing the upper nut of the thermostat and the hairpin.

Replacement of the thermostat on the "Kalina" must be carried out only after cleaning the parts surrounding this device from dirt, dust, as well as the remains of the old gasket. After this, it is necessary to apply a layer of sealant to the prepared place, and if it is not there, then you can use a special pad of paper.

Remember that the replacement of the thermostat ("Lada-Kalina" - a car where this procedure is carried out simply and quickly) should be carried out only on the prepared surface and with not having time to crystallize the sealant.

Thermostat setting process

When installing a new thermostat, remove the temperature sensor from the old one. On the upper fastening pin, you must screw the mass wire. After that, you can connect the hoses, and pour the liquid into the cooling system to the maximum level. It is necessary to remove air jams.

When the assembly is completed, it is necessary to start the motor, and thus check the tightness of all connections and the absence of leaks. Tighten the clamps, if necessary.

Replacement of the thermostat on "Kalina" should eliminate all signs and symptoms of its malfunction.

Quite often, when this device breaks down, it is customary to replace an extremely sensitive element. However, it is not uncommon for cases when it is not suitable for the dimensions or diameter of the shaft. As a result, a problem arises here. To avoid such trouble, experts recommend replacing the thermostat assembly.
