Fine fuel filter VAZ 2112 16 valves where is it located

On VAZ 2110 cars, a fuel filter is used to clean the gasoline entering the engine.

During operation, it gradually becomes clogged with debris, so the installation of a new consumable is periodically required. Replacing the filter is easy to do with your own hands, both on a carburetor VAZ 2110 and on an injection one.

On the VAZ 2110 the injector has two filters. The first is responsible for fine fuel cleaning, and the second for coarse cleaning. On cars with a 1.5 liter engine with 8 and 16 valves there is a filter 21120-1117010.

This non-separable disposable unit is assembled in a transparent plastic case, thanks to which the condition of the paper filter element can be assessed visually. The filter is the same as in all carburetor cars. In addition to this, mesh types of cleaning the fuel intake, fuel pump and carburetor are guarding the purity of gasoline.

The filter installed in the power supply system of injection engines is also made of paper. But due to the fact that it works under high pressure, it is assembled in a non-separable metal case.

The tenth VAZ model was supposed to be a sedan based on Samara, which later became the “ninety-ninth”. In fact, the index 2110 received a second-generation front-wheel drive car - a car without a proper name, which everyone knows as a “ten”.

Typical signs of filter contamination

• unstable operation of the power unit at idle;
• reduction in power, including without load;
• the engine “requires” a shift to lower gears before an ascent or hill;
• starting the engine is complicated, both “hot” and “cold”;
• Gases and exhaust periodically shoot out from the exhaust pipe, which indicates that the combustible mixture is unbalanced, depleted, or enriched.
• A burning smell can be heard near the car, which indicates incomplete combustion of the mixture inside the chamber and the formation of an excessive amount of soot.

Selecting a fine filter

The abundance of consumables on the market makes it difficult to choose. Surveys show that more than a third of “ten” owners use the BIG brand. The brands SCT, Bosch, Mann and Nevsky have proven themselves well.

“Experts” recommend assessing consumables visually by opening the casing. It is unlikely that such an “examination” makes sense. The differences are not fundamental; they are impossible to see with the naked eye. Universal advice - buy one that you don’t mind spending money on.

Replacing fuel filters

There are fewer problems with replacement on a carburetor engine. The fine filter is visible when you lift the hood. It is attached to the hose section with ordinary clamps. The arrow on the body indicates the direction of fuel movement: from the fuel pump to the carburetor.

Carburetor, fuel pump and fuel intake strainers require replacement extremely rarely. The manufacturer recommends cleaning them with a hard brush, rinsing them with gasoline or acetone and blowing them with air.

Location of fuel injection engine filters

A coarse strainer protects the inlet of the electric fuel pump located in the fuel tank. To access it, you need to remove the electric fuel pump through the hatch under the rear seat.

The designers of the VAZ 2110 placed the fine filter at the rear of the car under the tank.

From the point of view of ease of access, this is not the best solution. To get to the filter you need to drive the car onto an overpass. But do not forget that it works under pressure of several atmospheres. If the housing ruptures, a gasoline spill will cause minimal harm.

Replacement frequency

The manufacturer recommends changing the fine fuel filter of a carburetor engine after 15 thousand kilometers. Engines with injection - half as often, after 30 thousand km.

What tool will you need?

After the final decision has been made on self-prevention with subsequent replacement of worn-out elements, we check the availability of the following tools:

• set of heads;
• flathead and Phillips head screwdrivers;
• rags;
• new filter, according to the catalog article;
• empty container for storing waste.

According to the regulations, replacing the fuel filter on VAZ-2710 Priora, VAZ-2110 -2111 -2112, VAZ-2113 -2114 -2115 and VAZ-21099 cars with an injector must be carried out every 30,000 km . But, given the quality of domestic fuel, it is better to reduce the recommended mileage by at least 10,000 km. And change the fuel filter every 20,000 km. This definitely won’t make the car’s fuel system any worse. Some who have already had bitter experience in eliminating problems caused by a clogged fuel filter change it every 10 thousand kilometers. And to the question - “Why so early? ". They usually answer - “In this matter, it’s better to play it safe! ". And you can’t argue with them))). It’s no secret that the gasoline filter directly affects the service life of the fuel pump and injectors. Therefore, it is better not to forget about its existence and change it regularly. Otherwise, the risk of having to replace an expensive fuel pump or clean/wash injectors increases significantly!

Spare parts. On cars VAZ 21099 injector, VAZ 2110-2112, VAZ 2710 Priora, VAZ 2113-2115, two types of fuel filters are installed - threaded and clip-on. Therefore, before purchasing a filter, you need to get under the car and decide which filter is installed on your car. If someone does not know where the fuel filter is located on the VAZ 2110-2112, VAZ-2710 Priora, VAZ-2113 -2114 -2115, VAZ-21099 cars , then I will tell you. The gasoline (fuel) filter on the above machines is located near, or rather behind, the fuel tank (see photo 1).

The catalog number of the fuel filter with threads (nuts) is 2112-1117010-01 (see photo 2). The catalog number of the gasoline filter with clips is 2123-1117010 (see photo 3). When purchasing a threaded fuel filter, check whether it comes with copper or rubber sealing washers or rings (photo 4). Since washers/rings tend to wear out, tear, deform and get lost. And it will not be possible to install them again. And without them, gasoline will flow at the connection points between the fittings and the filter. Therefore, you should think about such a little thing as sealing washers in advance.

And by manufacturer brands . As they say, who can you trust with the process of cleaning fuel for your favorite car))). I recommend purchasing fuel filters from the following manufacturers: BIG (GB-320, GB-302), Nevsky filter, BOSCH, CHAMPION, MANN, FILTRON, hexen and SCT . This is how the TOP-8 turned out
