What are people guided by when buying domestic cars? Some are bribed by cheapness, while others like good maintainability and the presence of a large number of spare parts in car dealerships. In fact, the Russian auto industry has long begun to produce good cars. For example, Lada Granta confidently won one of the first places in the segment of popular cars. It is famous for its special popularity among our motorists. Low price, low fuel consumption, a large selection of spare parts, maintainability - all these qualities bribe motorists, forcing them to look more and more at cars made in Russia. This article will give some tips on car repair, for example, what to do if the Lada Grants fuel filter is faulty.
Reasons for replacing the filter element
The heart of any car is the engine. It will depend on his resource how long he will serve you, and although this resource is clearly spelled out in the technical specifications, the service life before overhaul will depend on the motorist himself. Meeting maintenance deadlines plays an important role in extending engine life. One of the important maintenance factors will be the replacement of the fuel filter at the Lada Grant.
What could be the reasons for replacing the filter element? What is the danger of operating a car with an old fuel filter? Any filter is a cleaning element. In our case, the fuel filter filters gasoline coming to the engine from the fuel tank. Gasoline is not a clear and clean liquid, as some people think. Yes, it is possible that at refineries, when distilling oil, gasoline turns out to be of high quality, like distilled water, but during transportation, during overflow from one tank to another, dirt or rust can get into it. That is why most cars are equipped with fuel filters.
Untimely replacement of the filter may affect the engine resource. Mechanical particles that are in gasoline, penetrating from the fuel tank, fall into the cylinder block. They do not burn when the mixture ignites, but settle on the walls of the cylinders and pistons. In contact with the rubbing surface, they gradually destroy it, thereby reducing the life of the engine. To prevent wear, it is important not to overtighten the filter.
Purpose of filters
The purpose of the filtering elements is mechanical cleaning of solid particles entering liquids or air. Fuel filters are divided into coarse and fine filters. The first are used in the filler necks of fuel tanks - these are strainers that clean gasoline from coarse impurities coming directly from the filling gun.
A fine filter is placed directly between the fuel tank and the car engine. It cleans gasoline from the tank from impurities. The car’s fuel tank, despite its apparent cleanliness, may contain mechanical impurities such as dust, dirt, rust, insoluble paint particles. The Lada Grant car is no exception. Replacing the fuel filter on time is a necessary measure to increase engine life.
How is the filter element
The fuel filter is a non-separable structure with a filter element inside. The element itself is a membrane made of porous cardboard and folded into a spiral. On the filter housing there are fittings to which hoses are connected. Since the membrane is laid in a certain way, the input and output of the filter are different. Therefore, when replacing, it is important to follow the direction. Typically, the direction of fuel movement is indicated by an arrow on the filter housing. At Lada Grants, the fuel filter has a similar design, and replacing it does not cause any difficulties.
Recommended filter replacement times
Almost always, motorists ask such a question. At what mileage does the filter need to be changed? Different cars have different ways. At Lada Grant, the fuel filter is usually changed after 30 thousand kilometers traveled, although some motorists recommend replacing it ahead of schedule. Why? Everyone knows that the quality of domestic gasoline cannot even be compared with pan-European indicators. Even despite the fact that gas prices are rising every day, and everyone is massively switching to Euro 5, no one can guarantee an improvement in its quality. The mechanical impurities that inevitably get in the process of transportation do not disappear anywhere, so many car dealers advise replacing fuel filters ahead of the deadlines recommended by the manufacturer.
How to find out that the filter is out of order
Is it possible to find out that the filter is clogged and needs to be replaced? A novice driver is unlikely to be able to identify such a malfunction, but with an experienced motorist the symptoms of filter pollution are probably known. If suddenly the car began to start poorly, especially during a cold start, it began to “triple”, to work unstably at idle, to stall — all this indicates that the filter is already clogged. In the presence of contaminants, the filter does not allow gasoline to pass through well: the pressure in the fuel system drops, the car runs intermittently. All cars without exception are subject to this, including Russian ones. How to change the fuel filter on the Lada Grant will be described below.
How to replace yourself
We will consider the replacement of the fuel filter on the example of the same "Lada Grants". Replacing this part is a simple process. Even a novice driver can handle it, without going to a car service. To find out where the Lada Grants fuel filter is, the car must be installed on a viewing hole or on a flyover. You can lift it on a lift, but it is unlikely that an amateur has professional equipment.
Removing and installing a filter
Usually the fuel filter is located next to the gas tank of the car. If the "Lada Grant" is 8-valve, the fuel filter is located behind the tank at the rear. To remove it safely, it is necessary to relieve pressure from the fuel system. To do this, find the fuse responsible for turning on the gas pump, and pull it out. In order not to suffer with a fuse, you can simply pull out the terminal of the fuel pump. We start the engine. After a little work, he will die out himself, since the fuel will no longer come from the tank - this means that there is no pressure in the system.
Two hoses are attached to the fuel filter, at the ends of which clamps are located. Having pressed a little on them, we take away hoses from the filter. We remove the filter from the bracket and put a new one. We put on the hoses in the reverse order, wait for a characteristic click. After replacing the filter, you need to insert the key into the ignition switch, turn it and, without starting the starter, wait for the pump to pump pressure into the system. Now you can start the engine.
Conclusion
Replacing the Lada Grant fuel filter was not a big deal. According to this principle, you can make a replacement on any other car.
However, you need to give a few words when choosing a fuel filter. Beware of fakes! Now the car market is awash with cheap Chinese fakes. Buying low-quality products, you risk your car. Fakes can lead to costly repairs, so purchase spare parts only from authorized dealers and be sure to ask the seller for a product certificate.
