How many fuel filters VAZ 2114. How often to change the fuel filter. How often to change the diesel filter
In order to avoid car breakdowns as little as possible, for vehicle needs regular maintenance, it should regularly replace worn parts. This is especially true for parts and spare parts related to the fuel system, since malfunctions in its operation directly affect the operation of the engine.
The fuel filter is one of the key parts of this system, its function is to screen out dirt, rust and other solid impurities contained in the fuel using a special filter paper. Thanks to the filter, purified gasoline enters the engine.
Every car owner faces the need to replace, so let's take a closer look at the following questions: how to replace fuel filter in VAZ 2114 on your own, in which cases it needs to be changed, which filter should be chosen for this car.
During operation, the filter paper cells of the gasoline filter become clogged, and its throughput drops, and this immediately causes interruptions in the operation of the engine. There are a number of signs that may indicate this:
- fuel consumption increases sharply;
- the car often stalls at idle;
- with an increase in speed, failures in the operation of the engine occur;
- there are problems with starting the engine;
- during operation, the engine troit, its power decreases;
- while driving, the car brakes without pressing the pedals;
- car jerks when going uphill.
There are many signs that the fuel filter is clogged, and they are quite diverse. In addition, you should be careful, since all these signs cannot unequivocally indicate a filter failure. They may also indicate malfunctions of the elements of the engine management system: electronic block control, crankshaft position sensors (DPKV), mass air flow (DMRV), throttle position (TPDZ), detonation (DD), as well as candles, wiring or regulator idle move. In order to make sure that the fuel filter is the cause of the unsatisfactory operation of the car, you can apply the following method. Connect the pressure gauge to the nipple located on the fuel frame of the injectors; start the car and check the fuel pressure. If the pressure gauge readings are lower than those provided for by the technical documentation for the car, then the cause of the malfunction in its operation is a clogged filter.
Where is the fuel filter of a VAZ 2114 car
The fuel filter is mounted in the form of a cartridge in the fuel line of a VAZ 2114 car. It is located on the bottom under the trunk, so you will need an overpass or pit to inspect and replace it. If you can't find where the fuel filter is in your car, take a close look at the part you can see. fuel system- it is located right behind the gas tank, in front of the exhaust pipe.
The fuel filter in the car serves to clean the fuel from mechanical impurities and protects the elements of the fuel system from clogging. Clogging of parts leads to interruptions in the operation of the engine or to its complete stop. In some cases, as a result of clogging of system elements, repairs may be required, which leads to labor and material costs. And in any case, it gives a lot of trouble to the owner of the vehicle.
FUEL FILTER FOR VAZ 2114 MODEL
The fuel filter is a filter element in the housing and is installed directly in the fuel line. The element itself can be fine and coarse cleaning, in many cars two filter elements are installed at once. Two elements are necessarily present in cars with diesel engine, since low-quality diesel fuel is very detrimental to engine parts. And the high pressure fuel pump does not tolerate dirt, and can fail.
Injection gasoline engines are more demanding on fuel quality than carburetor engines. And since the VAZ installed an internal combustion engine (ICE) with a fuel injection system (injector), the requirements for fuel quality for the car's internal combustion engine are high.
LOCATION
Two filters are installed in the VAZ 2114 - a mesh is used for coarse cleaning, which is installed on a submersible gasoline pump (the pump is located inside the gas tank), for there is a special filter in a metal case, it is located in the gasoline line of a front-wheel drive VAZ car.
To find out where the fine fuel filter is located, you need to look under the car. The filter is located under, between the fuel tank and the rear of the muffler. Its location is easy to determine by the fuel pipes that go to it. The fuel filter is attached to the VAZ 2114 using a metal clamp, which in turn is connected to the bottom of the car. It is not difficult to get to the filter element, but it is convenient to change it in a pit or a lift.
VARIETIES
As you know, the model) was equipped with an internal combustion engine with a volume of 1.5 and 1.6 liters. Therefore, the filters have a different design according to the type of fastening of the fuel pipes.
For machines with an engine capacity of 1.5 liters, the filters have threaded fittings, with a volume of 1.6 liters, the fuel line elements are attached using specific clips (clips). The parts are not interchangeable with each other, and therefore, before replacing, you need to make sure which type of element is needed acquire.
Cost from the manufacturer of the goods and from the region in which the part is purchased. The price can range from 150 to 600 rubles. Inexpensive are filters from MANNOL, Nevsky, Citron, Ecofil, LAAZ, AvtoVAZ. More expensive (but also better) products are FRAM, BOSCH, FINWHALE, MANN.
REPLACEMENT INTERVAL AND SIGNS OF CLOGGING
The manufacturer recommends replacing the VAZ 2114 fuel filter after 30 thousand kilometers. How much to actually change is another question. Quality Russian gasoline often makes it necessary to replace much more often. On average, it is recommended to change the filter element every 20 thousand km. They also change the filter if it is clogged prematurely. That the element is inoperative is indicated by signs of a clogged fuel filter:
- The machine loses power and does not develop the motor runs stably;
- VAZ 2114 twitches when driving, sometimes it completely stalls;
- When driving at any speed, the engine chokes, “sneezes”, there are periodic pops in the intake manifold;
- The car practically does not go uphill;
- The car starts and immediately stalls;
- And finally, the car cannot be started at all (gasoline does not enter the engine).
REPLACEMENT
There are many reasons why the internal combustion engine began to work unstably. And before changing the fuel filter to the VAZ 2114, you need to make sure that the matter is precisely in the clogging of the element. In any case, if the gasoline filter is clogged, the fuel supply will be uneven and reduced. The pressure is checked by a manometer, which is built into the car's fuel line.
Check the pressure in several modes:
- At idle;
- At high speeds;
- With a pinched pipe "return";
- On a dead engine.
We turn on the ignition, the fuel pump immediately pumps gasoline into the system, and pressure appears. The pressure gauge should fix a figure of the order of 3 atm. Start the engine and let it run for idling(2.5 atm.). When regassing, the pressure gauge needle in a working fuel system can rise to the number “3” and drop to 2.5 atm when the speed is reset. When the "return" is pinched, the pressure rises to 6-7 atmospheres. When the engine is stopped, the pressure should drop slowly, and the pressure gauge needle cannot suddenly go to zero. But clogged filter- not the only reason for the drop in fuel pressure in the gasoline path. fuel filter may be misinterpreted. Here can:
- Possess low performance fuel pump;
- Be a faulty fuel pressure regulator.
We found out where the fuel filter is located on the VAZ 2114, and the time has come to change it anyway. So it's time to start replacing.
INSTRUMENTS
To replace the fine filter element, you will need the following tools:
- Keys 10 and 13 to loosen the clamp;
- Keys 17 and 19 for unscrewing the fuel lines (filter with threaded fittings).
PREPARATION
We install the car in a pit (even better if the replacement is carried out on a lift), it will be very problematic to replace the filter on the ground. We prepare a container for gasoline (a basin or a plastic canister cut on the side). You will also need a rag if gasoline does spill. Before starting work, it is advisable to relieve the pressure in the fuel system, since when dismantling the fuel pipes, gasoline can fill the entire surrounding space.
There are two ways to relieve pressure:
- Remove the fuse responsible for the operation of the fuel pump and start the engine. The pump will not work, and after the production of gasoline in the fuel system, the engine will stall itself (after that, do not forget to return the fuse to its place!);
- Under back seat remove the hatch and disconnect the plug that supplies power to the fuel pump. Also start the engine and wait until the engine stops.
REPLACEMENT WORK
How to replace the fuel filter on a VAZ 2114:
- We install a container under the filter (in any case, gasoline will leak a little, despite the pressure relief);
- Do not forget to remove any of the terminals on the battery, it is better to de-energize the car during such work;
- With keys 10 and 13, we loosen the clamp that holds the fuel filter rigidly;
- With 19 keys we keep the filter from rotating, and with a 17 key we unscrew the fuel line fittings (for a 1.5 liter engine). For a 1.6 liter engine, we snap off the clips and pull off the fuel hoses.
- We dismantle the old filter element and install a new one. We fasten the fittings in their places, tighten the clamp. Everything is very simple, the work takes no more than half an hour.
After replacement, a performance check of the new part is required. You should start the engine and make sure that the replaced filter does not leak, and the engine runs stably and gains momentum well.
SAFETY
Gasoline is a flammable and poisonous substance, therefore, when carrying out work related to its flow, it is necessary to observe elementary safety measures:
- Do not smoke or use open flames to avoid a fire;
- It is necessary under or other means for extinguishing a fire (construction sand, water);
- Try not to get gasoline on the skin and oral mucosa;
- Gasoline leaks should be wiped up immediately with a rag and then stored separately for disposal. After contact with gasoline, rags can no longer be used!
- The fuel line fittings should be dismantled carefully, without sudden movements.
- The fuel filter must be installed in a certain position, there is an arrow on its body. The arrow indicates the direction of fuel flow.
- After replacing the filter, turn on the ignition two or three times without starting the engine. The fuel pump needs to pump fuel into the system.
The fuel filter is the same consumable item as gasoline, the more fuel passes through it, the more it becomes clogged, and the sooner its replacement.
The arrow indicates the direction of fuel flow
How often should the fuel filter be changed? The range is very different: on some machines it must be changed every 10-30,000 kilometers, on others it is designed for the entire period of operation of the car.
If not changed in time..
All fuel passes through the filter, bringing with it all sorts of debris - dirt that has got in from the outside, corrosion products, etc. Over time, the filter element becomes clogged and stops passing the required amount of fuel through itself. Since the throughput drops, less fuel passes through it, and the pump still works with the same capacity, where will the extra gasoline go? That's right, it will increase the pressure in front of the filter and thereby increase the load on the pump, which will lead to its early wear.
On the injector, a clogged filter will be affected by a pressure drop in the rail, which, when driving, will show weak acceleration during hard acceleration and the gas pedal will not be as responsive as the first noticeable sign of a clogged fuel filter. And all due to the fact that the mixture will turn out to be lean, there will not be enough fuel. Most likely, the oxygen sensor will show this and the tidy will light up " check engine”, you will have to drive to find out what kind of mistake it is, hand-ass masters will disassemble half the car, because they don’t know what computer diagnostics they do with new spark plugs, a new fuel filter and normal rail pressure and a charged battery. Therefore, change the fuel filter on time.
