Car VAZ-2110: replacement of a cooling liquid

In the process of the internal combustion engine, a huge amount of heat is generated. For this reason, in order for the motor to operate normally, it must be forced to cool. For this, a special liquid is used - antifreeze (antifreeze). It eventually loses its properties.

The two-year-old antifreeze cools the engine less and less efficiently. This is extremely unsafe. Let's look at how a coolant is replaced on a VAZ-2110 car. This information will be useful to all novice car owners.

Coolant resource

Many are convinced that modern cooling fluids need to be replaced after 100 thousand km of run. In fact, this is not so. The manufacturer recommends to carry out the replacement of antifreeze every 2 years of operation of the car or every 45 thousand km. But on sale there is also more resource cooling liquid (VAZ-2110). How to replace it? This is done quite simply.

When to change the antifreeze

If the color of the coolant in the expansion tank has changed, if the antifreeze became rusty and the oil film is noticeable on the tank surface, this indicates the need to replace the coolant. Also one of the signs that a coolant replacement is needed on the VAZ-2110 is the frequent causeless overheating of the engine. But we must remember that the VAZ-2110 is designed for driving at relatively high speeds. If the car will be operated at a low speed, the antifreeze can boil and from this.

Toxic acid is also susceptible to antifreeze, which has lost its properties. But the problem can be in the sensor. Sometimes it helps to solve this problem replacing the coolant sensor. VAZ-2110 also has a coolant sensor, which shows the degree of overheating on the instrument panel. Another reason, due to which it is necessary to replace the antifreeze - this is leakage. On these models of cars (meaning all the "tenth" family) is a normal and fairly common situation. But a simple replacement is not enough. It is necessary to thoroughly investigate the entire cooling system to eliminate the problem. Sometimes these leaks are so insignificant that they are difficult to detect. Tosol can boil and evaporate through unknown for the owner of the path. The practice of servicing the cooling systems of domestic cars shows that these leaks can also be in the clamps. The problem can be solved by replacing the elements.

If the antifreeze boils, but is at a normal level, its color has not changed, this indicates the occurrence of air bubbles in the system.

Which coolant to choose?

The first step is to understand how much antifreeze is needed to replace it. According to the passport data, the filling level of the antifreeze on the VAZ-2210 is 7.8 liters. But here to merge from the system it is possible only 7 - it is impossible any more. Therefore, to replace the coolant with VAZ-2110, it is necessary to purchase 7 liters of antifreeze. When choosing a liquid, follow certain rules. It is best to purchase antifreeze, which is suitable for a specific model of the car. You can not mix different types of liquids of different colors. It is best to purchase the same antifreeze that was poured into the system before the replacement. Nobody knows how a "cocktail" of two different cooling liquids can behave. There have been cases when such antifreeze began to foam. The machine quickly boils from this.

Antifreeze is not only a finished product, it can also be sold in the form of concentrates that the car owner dilutes with distilled water. It is also necessary to pay attention to this.

The replacement process

Let us consider how the cooling liquid is replaced. VAZ-2110 (injector) - a very simple car, so this operation can handle even the girls. But it is necessary to do everything correctly and strictly according to the instructions.

Work on replacing the antifreeze is best performed, having taken care of your own safety: protect your eyes and hands. Do not turn off the expansion tank if the antifreeze has already begun to boil.

The machine must be installed on a flat surface. Then the car is de-energized. To do this, simply remove the terminals from the "minus" on the battery. Remove and the ignition module together with the bracket. So you can get more convenient access to the engine block. Then, under the drain plug, put any capacity where the cooling liquid from the system will flow. First, unscrew the plug of the expansion tank, then drain. It is necessary to wait until all the liquid has gone and the outflow will not stop. Next, the pelvis or any other container is placed under the radiator - its plug must also be unscrewed. It is necessary to drain as much liquid as possible (but the more, the better). When all the antifreeze is poured out, the drain holes must be thoroughly wiped, as are the plugs themselves. Also, it is not superfluous to check the condition of all the nozzles. If the antifreeze often boils, then this does not have the best effect on the condition of the rubber parts. Check their density. "Oak" pipes must be replaced with soft new ones.

To replace the VAZ-2110 coolant really successfully, you need to consider a few more points. On the injector remove the hose where it connects to the nozzle heating the throttle body. Next, look how much liquid could be drained, and pour about the same amount through the expansion tank, until the system is completely filled. It remains only to tighten the cap of the expansion tank tightly, return the inlet hose, place the ignition module in place, connect the wires and start the motor. It is necessary to let the engine run at idle speed for a while. Sometimes it happens that the level of fluid after a while falls (although it was filled with 7 liters). This indicates that there was an airlock in the system, and it "dissolved". In this case, it is recommended to add the antifreeze to the desired level. If the antifreeze is over, you can supplement the volume with distilled water.

Replacement of other parts of the cooling system

Sometimes the problems associated with the operation of the cooling system can be solved by simply replacing the coolant. Its unsatisfactory work can be associated with malfunctioning or failure of various elements of the system. Most often, a water pump ("pump"), coolant temperature sensors go out of order. Sometimes replacement of a supply pipe of a cooling liquid can be required.

VAZ-2110 - a car, which should be closely monitored. It's easier to fix the malfunction than to completely change the cooling system.

water pump

If the water pump fails, it can cause serious problems. The engine overheats, and can head.

Among the symptoms, which determine that the pump came out of standing, you can distinguish the following:

• Leaks of antifreeze from the pump.
• Noise during the operation of the device.
• Poor pressure in the system.
• Weak circulation of the coolant circulation along the contours.
• High engine temperature.
• Reducing the volume of antifreeze.

Diagnosis of the pump on the car VAZ-2110

To check the performance of the pump, heat the motor to its operating temperatures, and then squeeze the upper branch pipe of the radiator. At the same time, the hand needs to feel that the coolant moves through the system. If so, then everything is in order. Also, when diagnosing, pay attention to the sounds of the pump. If there is a rumble, then the bearing has failed. In this case, the VAZ-2110 is replaced with a coolant pump.

If the diagnosis of these methods did not reveal any problems, then inspect the timing belt cover. There may be moisture. The pump is located just under the lid. If there is a source of leakage somewhere, then on the tray you will see drops of antifreeze.

Sensors

Sometimes the problem is not in the liquid, and not even in the pump. The owners of cars have a lot of trouble with temperature sensors. They periodically fail. The replacement of the coolant temperature sensor can correct the situation .

VAZ-2110 - the car on which the system of a cooling liquid of the closed type is established. Its main component is antifreeze.
