Windscreen washer pump provides sufficientpressure in the system to supply water to the glass. This is one of the most important parts in a car, which is always necessary, and not only in bad weather. Let's take a look at where the windshield washer motor is installed, what are its features and how to replace and clean it.
The principle of the motor
Для создания необходимого давления и подачи воды This motor is used. Its design is different depending on the brand. This is due to the fact that sometimes water supply is required not only on the windshield, but also on the rear view glass. In general, the principle of action does not differ from that characteristic of any other water pump, it’s just that it has small dimensions and works not only with water, but also with the washing fluid, that is, in an aggressive environment. The windshield washer motor can fail, like any other node in the car, but unlike the same engine, every driver can easily repair it independently.
Typical causes of node failure
For a long time of car maintenance, most car service specialists distinguish the following "standard" motor failures:
- terminal damage;
- hose disconnection;
- nozzles clogged;
- washer switch malfunction.
That such problems occur most often.The most banal and simple - jumped off the hose under the hood. The fluid enters and simply pours into the engine compartment. In general, the problem is non-critical, it is enough just to fix the hose - and everything will immediately work.
Как показывает многолетняя практика, сам механизм simple and extremely reliable, so it rarely fails. Another thing is that the contacts oxidize and may not give the desired signal. Or, everything was beaten with rust and dirt to the point that the pump could not push the plug. Situations are different, in any case, if the windshield washer motor does not work, it is necessary to understand and look at what is the matter. Sometimes the reasons lie on the surface.
Details of the whole
As you can see, the window washing system is not socomplex. It consists of several simple components: a motor, a tank and injectors. Of course, there are also highways through which the washing fluid passes. The pump pumps fluid that goes under pressure to the tee. Tee - washer fluid dispenser. Further, through the nozzles, it is sprayed directly onto the center of the windshield and wipers spread around the perimeter.
How to replace the windshield washer motor
As noted above, the designmotor can vary depending on the brand of car. This also applies to its location. Nevertheless, if you can find the washer tank, then problems should arise. What you will need from the tool is an ordinary flat and Phillips screwdriver, as well as a set of keys.
As for the components, their price tagis small. Purchases will cost 500-1,500 rubles, depending on what you purchase. Then go directly to the replacement. We find a tank and a motor. Disconnect the terminals, they are immediately desirable to check. If there is a large amount of rust, then it must be carefully removed and try to check the performance of the system.
We continue repair work
После того как вы определили, где находится windshield washer motor, and disconnect it, you need to perform the following steps. Drain the liquid, if any in the system is available. To do this, disconnect the hose and fitting. Next you need to push the intake of the sealing sleeve. The easiest way to do this is with an ordinary flat screwdriver. In doing so, we try not to damage anything, since the products are quite fragile. Now we can turn off the pump from the tank and start cleaning it. You can clean it in any convenient way, the best is with an ordinary eraser - simply and fairly quickly.
How much does the windshield washer motor in caseits breakage? If the domestic cars, a couple of hundred rubles, if a foreign car - more. Usually 1,000 or more. But you need to change it only in the presence of obvious mechanical damage or critical wear.
Inspect the rubber seals
Most often glands and gaskets and arecause inoperability of the system. This is due to the fact that over time, rubber dubeet, cracks and so on. Accordingly, the gasket does not perform its functions. If during repair you find a malfunction of the sleeve, then replace it. So you significantly extend the life of your pump. Same concerns also other epiploons. Everything that looks bad or cracked, we try to throw it away, and put a new one.
We approach the final part
Практически всегда мотор омывателя лобового glass is not folding. That is, you will not be able to inspect its internal parts, such as the stator and the anchor. The case is filled in at the factory, only the replacement of the failed part is provided. But we are not looking for simple ways and we can disassemble the undecided. For this we need a hacksaw. With its help, we make a neat propyl on the pump step and use a flat screwdriver to divide it into two halves.
From the motor stator gently pull anchor withbrushes. At the same time it is important not to bend or break anything. Then take up the cleaning. We rub everything to shine and try to completely get rid of corrosion. We change the gland, because of which the fluid leaked, and collect everything back. To do this, use a soldering iron or glue. We check the performance. Everything should function without any sign of wear.
Finally
You should never ignore security onthe road. It would seem that the windshield washer motor has tiny dimensions, what kind of responsibility can it have? But if you seriously think about it, imagine that at a speed of 120 km / h it splashes mud into the windshield, but you cannot clean it or the wipers just smear dirt, and no water comes out of the nozzles. As a result - emergency braking or accident. For this simple reason, such a small simple node should be serviced periodically.
