How to drain the coolant from the system completely

In this article, we'll talk about how to drain the coolant from the engine. It is necessary to conduct this procedure for various reasons. For example, when repairing the internal combustion engine cooling system . Even the replacement of the thermostat requires the coolant to drain. But let's look at the main reasons for this procedure in more detail. From the article you will also learn how to fill the system with liquid and make a pumping - getting rid of air plugs.

The main reasons for draining a liquid

As it was said earlier, it is necessary to get rid of the liquid even when changing the thermostat. In addition, you need to drain the antifreeze when replacing the nozzles, water pump, repair the stove. Therefore, you need to know how to drain the coolant in the planned maintenance of the car systems. It is worth noting that antifreeze has some resource. It contains additives that evaporate during the operation of the car. These additives are necessary for lubricating the water pump, which rotates when the engine is running. If water is added to the cooling system, the pump will stop lubricating, which will lead to premature wear.

The additives, which are contained in the antifreeze, allow the nozzles to work sparingly. Rubber is much longer, does not crack, therefore, there is no need to monitor its condition. But these additives volatilize, as they do not withstand a constant sharp temperature drop. The approximate service life of the antifreeze is 90,000 kilometers. From here it is possible to draw an analogy, in fact to replace a liquid pump it is necessary at the same run. The conclusion is this: during the replacement of the pump it is necessary to fill in fresh liquid.

How to merge coolant

Before draining the coolant, you need to prepare for this. From tools and devices you need a capacity of about 10 liters. It is enough to fit all the liquid that you will drain. In addition, you need a key to 13. It is advisable to use an end or a combination key, since with their help it is more convenient to work. In rare cases, pliers may be required. If you have an engine protection installed, you need to remove it. So, there are two drain holes - directly in the internal combustion engine block and in the lowest part of the radiator. But notice that getting rid of the whole liquid is quite difficult. Therefore, we need to resort to some tricks.

They will be discussed below. First of all, you install a tank under the drain hole on the radiator. If necessary, cover the generator with a piece of film. Please note that the engine must be cold so that you do not get injured. In cooling systems of hermetic type, the liquid will not flow until you start to unscrew the plug on the expansion tank. After all the antifreeze has poured out of the radiator, you need to close the drain hole in it. The key on the 13 twist plug in the engine block. Similarly, get rid of the antifreeze in the cooling jacket.

Small tweaks

But there are small nuances that will help you completely get rid of the fluid in the system. It is worth noting that not everyone knows how to completely drain the coolant. And it's quite easy to do this. Do not forget that the stove is connected to the motor cooling. Therefore, it must be fully opened, so that all liquid is removed from the radiator. In addition, you can do a little trickier - put the car in such a way that the rear part of it is higher than the front. This will allow the antifreeze to flow through the hole in the radiator. In this case, even from the stove, it will be directed to the main hole. Similarly you can do when pouring coolant. The only difference is that the front of the car should be higher than the rear. Thus, the antifreeze will tend to maximally fill the radiator of the stove. And now a little about how to refuel the system.

Coolant fill

Before you start pouring coolant into the system, make sure that all drain holes are tightly closed. This will avoid unnecessary costs. The procedure for refueling the cooling system on the "classic" and the VAZ family is slightly different, starting with model 2108. The latter uses a sealed system in which the liquid is at a certain pressure. It is regulated by means of two valves which are in a stopper of a broad tank. Hence the conclusion - to drain the cooling liquid VAZ-2110, you need to open the cork. There is another small feature - as such, the pumping system is not provided. It is enough just to fill in the antifreeze, warm up the engine to operating temperature and give it some time to work. But in the "classic" you need to act in a slightly different way. In general, the difficulties with refueling the coolant system should not arise. The main thing is to know exactly how much liquid is in the system.

conclusions

Now you have an idea of how to drain the coolant, "Nexia" or the domestic dozen, it does not matter at all. Works are carried out similarly both on domestic machines, and on import. True, there are small features for each model of the car. For example, the location of the drain holes may not coincide. But they will still be on the radiator and the ICE block, because these are the largest elements of the cooling system. In the engine there is a powerful return of heat to the liquid, and in the radiator the latter lowers its temperature.
