Engine cooling system presents forcar of particular importance. After all, it provides the cooling of the internal combustion engine with a special liquid - antifreeze. SOD should be washed out from time to time, but many drivers forget the importance of this operation. If this is not done in time, dirt in the radiator will induce engine overheating and an increase in consumption of antifreeze. In today's article we will look at how to wash the cooling system properly with your own hands.
About sediment
The design of the radiator is special in that dirt accumulates on it, not only outside but also inside.
How to wash the car cooling system? Preparation process
First we need to open the SOD valve anddrain the whole antifreeze. Next, distilled water is poured into the system along with a descaler (such as are sold in automobile and hardware stores). The whole essence of the washing process is as follows. After entering the mixture of water with an additive, the scale collapses when the engine is running. Further, its particles together with the liquid are poured out. Most often, this mixture after washing has a very turbid and sometimes yellow-green hue.
Before flushing the cooling system(with serum or additive, it does not matter), you need to remember that the whole process is carried out in 3 stages. First, the radiator itself is washed, then the engine, and then the stove radiator. Let us examine all the details separately.
How to flush the cooling system? Descaling the radiator
First you need to drain the coolant (coolingfluid) from the system and disassemble the pipeline. To do this, remove the hose from the base of the radiator and the top of the tank. How to flush the cooling system further? In order for washing to be effective, it is necessary that there be a good pressure. Therefore, a garden hose should be inserted into the radiator pipe. Under the pressure of water, he washed the inside of the element. It is necessary to wash until dirty water stops flowing from the bottom of the radiator.
Now clean the parts near the engine.How to wash the cooling system VAZ? For this we need high water pressure and the same garden hose. The latter is inserted into the outlet thermostat. The process occurs as in the previous case and lasts until clean water begins to flow down, without dirt and sediment.
Cleaning the radiator stove
Before rinsing the cooling system, weyou need to open the heating tap and remove all hoses from the stove. Insert the flushing garden hose into one of the opened fittings and turn on the pressure. The whole process lasts until clean water starts to flow from the second fitting.
Rules for draining and coolant
In order for the parts to be washed, the SOD really yields a result, it is necessary to know the rules for filling and draining coolant.
Recommendations for draining antifreeze
To drain the coolant, you can lift the frontcar up, however, the fluid can safely be removed and with a horizontal position of the body. When removing the terminals can only remove the "mass", that is, "-". On cars VAZ 2111 when you open the cork of the cylinder will have to unscrew the ignition module. On vases of the model 2110 and 2112, the plug opens without any additional actions with ignition. Before flushing the cooling system, “Lanos” and other passenger cars should be checked for the level of ICE heating. Remember that the drain antifreeze in any case should not be made "on hot."
Next, you should remove the cork of the tank, and under the internal combustion engine to put a container into which the liquid will flow. Then unscrew the plug to drain the mixture from the cylinder block.
When the main part of the fluid stopsrun out, unscrew the radiator cap, located at the bottom. Under this item is also necessary to put a container to drain. At the expiration of all operations, you must re-tighten all traffic jams on the car.
Antifreeze Bay
After all the deposits on the walls of SODwill dissolve and come out with distilled water to the outside; you should refill the new antifreeze in the system. In order to avoid the formation of air plugs, the bay process should be done as follows. For a carburetor internal combustion engine, loosen the clamp and remove the hose that leads to the carburetor preheater nipple. If it is an injection vehicle, then it is necessary to remove the hose of the choke fitting for the throttle tube. After that, the new antifreeze is poured into the expansion tank and is distributed evenly throughout the system. At the same time, traffic jams at the bottom should be closed.
As antifreeze topping is recommended to dosmall stops. This is necessary in order. so that the fluid fills all the taps in the system. If the level of antifreeze in the expansion tank remains for a long time at the same level, it means that the SOD is completely filled with antifreeze. Then all hoses are mounted back. The cover of the expansion tank at the same time twists only half. This is necessary so that a lot of pressure is not generated in the system. If the cap is screwed completely, next time it will be very difficult to unscrew, as the antifreeze with air expands and acts on all parts of SOD, including the connections. If the latter were badly clamped with a yoke, they can be pulled out. Further movement of the car in this case is impossible. Therefore, always twist the cover halfway.
After a few minutes of ICE operation after the bayNew antifreeze should unscrew the cap and re-look at the level of the coolant. Most often it decreases, so you have to top it up to a normal level.
How to get rid of the airlock?
From time to time in the engine system mayair plugs that interfere with the normal cooling of the motor. The easiest way to eliminate this problem is to drive in the front part of the car on the overpass and let it stand at an angle for several minutes in a normal state. At the same time, it is recommended to “podgazovyvat” pedal, so that the engine worked at different speeds. But not always this method is effective. If this method did not help, you need to perform the following operations:
- Remove the pipe from the throttle assembly, which leads to the reverse flow of coolant.
- Add antifreeze to the tank.At this time, he should go out of the socket. If this is the case, then we plug the nozzle and wait for the fluid to flow from the hose. When the coolant does not go, start the engine and plug the pipe with a finger.
- Wait for the moment when the antifreeze does not appear from the hose of the throttle assembly.
- Close the nipple. Next, hold it until coolant runs out of the hose.
- Tighten the nipple and clamp the mounting clamp.
- Start the engine and heat it to a working temperature of 90 degrees.
- Turn on the heater. If a hot stream of air went into the cabin, the problem with the airlock is eliminated.
Next we just have to set backcooling pipe throttle unit, and check the level of coolant in the tank and, if necessary, bring it to normal. At this point, the question "how to wash the engine cooling system with your own hands" can be considered closed. Finally, we note that in the event of a critical increase in the temperature of the internal combustion engine, you must immediately turn off the machine in order to prevent the engine from overheating. The most common cause of this is the airing of the system or an insufficient amount of antifreeze itself.
Conclusion
So, we figured out how to flush the cooling system."Priora VAZ" and many other passenger cars are repaired in this way. The use of special anti-scale additives and distilled water are the best way to remove excess deposits on the walls of SOD.
