How to drain the coolant: detailed instructions

From the article, you will learn how to drain the coolant from the engine correctly, not the Strait it on the ground or floor in the garage. Reasons for discharge may be several. It and its complete replacement, and repair pumps, thermostat. If you are installing new pipes or radiators, can not do without draining fluid from the system. But you need to follow a certain algorithm to work was carried out quickly and efficiently. First you need to talk about the typical faults in the cooling system of any internal combustion engine.

Signs of failure of the cooling system

Very often damaged gasket under the cylinder head, decreases the amount of coolant in the system. In this case, the liquid can escape, even in small amounts, in the combustion chamber. This is reflected both in the engine and in the operation of the refrigeration system. It is also worth noting that with proper thermostat during engine warm-up temperature of the primary radiator of the cooling system is not changed. So if after two or three minutes after starting you touch the lower and upper ends, and they are hot, then there is a problem with the thermostat. Most likely, it the valve is in the position in which the fluid circulates in a large circle. On the other hand, if even after reaching 90 degrees the temperature of the pipes remains low, it can be judged that the jamming has occurred at the position at which the liquid circulates in a small circle.

What you need to know before you drain the fluid

Most importantly – always do work only on cooled down engine! Otherwise, you will get severe burns on the body. Wounds heal very long, and if we take into account that antifreeze (antifreeze) is poisonous, then you are at risk of severe allergic reaction. To Ambaritsa hot antifreeze is much worse than plain water, as it fat, because the cooling system plays a minor role in the lubrication of the bushing or bearing of the pump. And you know what it's like to Ambaritsa boiling oil (e.g., vegetable). The effect is about the same. To carry out draining, you'll need the key 13, the capacity and pliers. But the latter is necessary in exceptional cases, which will be discussed below. Pay attention to the coolant reservoir, it has a tube. It is described a little below.

How to drain the fluid?

So, first, prepare the machine for repair. While the engine cools down, you remove him of his protection, she would interfere. The total volume of coolant in the system – about 9 liters. Freeing up space, you can relax a bit, waiting for full cooling of the antifreeze. Establish under a drain hole on the radiator capacity, estimate the approximate direction of the jet. For example, on the domestic front-wheel drive cars when draining the fluid stream enters on the back cover of the generator. It's not very good as you can get short circuit and burn the generator. So before you drain the coolant, it is best to cover with waterproof material. Install a small trench so that the spray fell on him, and all the liquid without leaving residue dripped into a container.

Please note that without unscrewing the tube from the surge tank fail to drain all the fluid, since the system is sealed. After I drained the fluid from the radiator, close the hole in it. With key 13 Unscrew the second cap. It is located on the engine block. Similar install a small gutter to direct all liquid flow into the container. Without these steps, replace the coolant VAZ 2114 impossible. The most important thing during fluid drain – open the valve on the stove! It is also desirable to set the car so that its front end was lower than the rear. This will allow all the liquid to drain to the drain holes.

What is better antifreeze or antifreeze?

This is a very common question among car owners. And the answer will sound like the question “What is better: Coca-Cola or "Baikal"”? In fact, it is the same, only "Baikal", as well as antifreeze, – is a domestic product. And abroad the more popular Coca-Cola and antifreeze. Antifreeze – this is antifreeze. Any liquid that does not freeze in the cold – the antifreeze. But there are differences. Before you drain the coolant to replace, is to learn about the nuances.

Antifreeze was developed by domestic scientists nearly half a century ago, it is widespread, and is not inferior to foreign analogue of (called the ‘freeze”) in its characteristics. Different antifreeze blue color and a completely different structure. Unfortunately, foreign brands this liquid a lot more additives that improve its performance, prolong service life. And what to choose – Tosol or antifreeze (the price of these liquids are almost identical), only you can decide.

Replace thermostat

You only Need to replace a failed thermostat. It is located directlythe internal combustion engine. It is connected to several nozzles. Typically, one goes to the expansion tank, the second – radiator, the third – to the water pump, the fourth made the connection to the cooling jacket of the cylinder block. Please note that all work should be carried out only after full cooling fluid in the cooling system. And before you start the repair, you need to completely drain the antifreeze from the system.

Twisting the clamps, which are located on the pipes then take them off. Please note that in this case must be completely drained antifreeze. The price, incidentally, is about 700 rubles per canister volume of 10 liters.

Conclusion

If you notice that the temperature has reached a critical point, it is necessary to determine the cause of the malfunction, and quickly take action to immediately resolve.

On the other hand, excessively low temperature of the engine may also cause increased wear and tear of all elements of the internal combustion engine. Air-fuel mixture almost evaporates, it takes away from all of the walls of the cylinder a film of oil. No matter what the symptom of failure, hypothermia, or excessive heating, the system has a fault which should be corrected.

Now you know how to drain the coolant from the internal combustion engine. Success!
