How to flush a car cooling system

The engine cooling System is for a vehicle of particular importance. In fact it provides cooling of the internal combustion engine due to the special fluid – the antifreeze. From time to time SOD needs to be flushed, however, many drivers forget about the importance of this operation. If the time this is not done, the mud in the radiator will induce overheating of the engine and increase the consumption of antifreeze. In today's article we'll look at how to correctly flush the cooling system with his hands.

About the deposits

The design of the radiator is special because dirt accumulates on it not only outside but also inside. The Role of sediments can play items such as motor oil, rust, but most of the basic scale. The latter appears if instead of antifreeze in SOD pour ordinary water. As for corrosion, the phenomenon is a rarity, since most radiators are made of copper and aluminum. The presence of rust says about the poor Assembly of the part.

How to flush a car cooling system? The process of preparation

First we need to open the flap of the SOD and to drain the antifreeze. Further, the system is filled with distilled water with an additive for descaling (such as sold in automotive and hardware stores). The whole point of the washing process is as follows. After exposure of a mixture of water with the additive scale when the engine is destroyed. Further, its particles together with the liquid pour out. Most often this mixture after washing is very turbid and sometimes yellow-green tint.

Before you flush the cooling system (serum or additive - doesn't matter), you need to remember that the whole process is done in 3 stages. First, flushing the radiator, then the engine, and after – the heater radiator. Consider all the parts separately.

How to flush cooling system? Descale sink

First we need to drain the coolant (coolant) from the system and dismantle the pipeline. It is necessary to remove the hose from the bottom of the radiator and the top of the tank. How to flush the cooling system on? In order for flushing to be effective, you need to have good pressure. Therefore, in the outlet of a radiator, insert a garden hose. Under the pressure of the water it will wash the inside of the element. It should be washed until then, until the bottom of the radiator will stop the dirty water.

Now we clean the parts near the engine. How to flush the cooling system Vase? For this we need high water pressure and the same garden hose. The latter is inserted into the hole of the thermostat. The process is similar to the previous case and lasts as long as the down will not begin to flow clear water, no dirt and deposits.

Rules of the drain and the Gulf coolant

In order to rinse parts SOD really gave the result, it is necessary to know the rules of Gulf and drain the coolant. There are several. First, the antifreeze is filled and drained only after full cooling of the engine. Secondly, before you start flushing you need to check the cap of the expansion tank. It must be open. And thirdly, you should follow safety rules. As additives are highly abrasive chemical substances, work with them only in rubber mittens, so as not to damage the skin.

Recommendations when draining antifreeze

Drain the coolant, you can lift the front of the car up, but the liquid can easily be removed and horizontal position of the body. When removing the terminals, you can extract only the “mass”, that is “–”. On cars VAZ 2111 when you open the tube the cylinder block will have to Unscrew the ignition module. On Vases of the model 2110, and 2112 the tube open without further action from the ignition. Before you flush the cooling system, “wheels” and other cars of the automobile type should be to check the heat level of the engine. Remember that the discharge of antifreeze in any case should not have made “hot”.

Next is to remove the tank tube and under the engine to enclose the container, which will leak fluid. Then unscrewed the drain plug of the mixture from the cylinder block.

When the main part of the liquid stops draining, Unscrew the radiator cap, located at the bottom. Under this detail also need to enclose a drainage container. After all operations you must re-tighten all the plugs on the car.

Gulf antifreeze

After all the deposits on the walls SOD will dissolve and will come off along with distilled water outside, you have to re-fill the system with new antifreeze. To avoid the formation of air pockets process Bay must do the followingway. For gasoline internal combustion engine need to loosen the clamp and remove the hose that leads to the fitting of heating the carb. If this is a fuel injected car, it is necessary to remove the hose fitting of the heated tube reactor. The new antifreeze is poured into the expansion tank and is distributed evenly throughout the system. The tube bottom has to be closed.

As the topping of the antifreeze is recommended to do a small stop. This is in order. the liquid filling all the taps in the system. If the level of antifreeze in the expansion tank remains for a long time on the same level, so SOD completely filled with antifreeze. Then all the hoses are mounted back. The cap of the expansion tank when it is twisted only by half. This is to ensure that the system is not formed a lot of pressure. If the cap to tighten completely, next time it will be very difficult to Unscrew, as the antifreeze with air expands and affects all parts of ODS, including the nozzles. If the latter were poorly clamped by the clamp, they can pull out. Further movement of the vehicle in this case is impossible. So always tighten the cap a half.

After a few minutes of engine operation after the Bay of new antifreeze must Unscrew the cover and re-look at the coolant level. Most often it is reduced, so you have to refill it to normal levels.

How to get rid of air locks?

From time to Time in the engine system may form air pockets that prevent the normal cooling of the motor. The easiest way to resolve this problem – to drive the front of the car on a rack and allow to stand her on the corner a few minutes in a running condition. In that case “to podrazumevati" of the pedal so that the engine working at different rpm. But not always, this approach is effective. If this does not help, you need to perform the following operations:

1. To Remove a branch pipe with a throttle node which leads to the reverse flow coolant.
2. Pour antifreeze into the tank. At this time he needs to go out of the pipe. If so, then plug the fitting and wait until the liquid will flow out of the hose. When coolant does not come on, start the motor and plug the nozzle with your finger.
3. Wait for the moment when the antifreeze appears the hose on the throttle node.
4. Close fitting. Then keep it for as long as the hose does not flow coolant.
5. Pull the pipe and clamp retaining strap.
6. Start the engine and warm it up to operating temperature of 90 degrees.
7. Turn on the heater. If the salon went hot air flow problem with the air tube removed.

Next we just need to set back the cooling nozzle throttle node, and check the coolant level in the reservoir and the need to bring it up to standards. In this question “how to flush the engine cooling system with their hands” can be considered closed. Finally, we note that in case of a critical rise in temperature of the internal combustion engine should immediately turn off the machine in order to prevent engine overheating. The most common cause of this is the airing system or inadequate number of antifreeze.

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 additives against limescale and distilled water are the best means to remove excess deposits on the walls of SOD.
