Device engine VAZ 2115 injector 8 valves – VAZ-2113, -2114, -2115 manual operation, maintenance, repair, tuning – Mirglobo

VAZ-2115 Samara-2 is a front-wheel drive sedan, the first representative of the updated Samara family of cars.

The VAZ 2115 car is the founder of the family codenamed Samara-2. The model range includes the 3-door VAZ 2113 hatchback, the 5-door VAZ 2114 hatchback and the VAZ 2115 sedan itself. The Samara-2 family is a modernization of the VAZ 2108, 2109 and 21099 models, respectively.

In 1997, the VAZ 2115 sedan began to be assembled at Pilot Industrial Production (EPP); in 2001, assembly began on the factory assembly line. Currently, the VAZ 2115 is on wide sale; three versions are available: standard (21150-20), norm (21150-21) and luxury (21150-22). In terms of price, the car occupies an intermediate position between the Samara and the tenth family.

The appearance of the car has noticeably changed - the front and rear parts have been changed, the interior has been updated, while the sides, doors and roof remain the same. The new model is distinguished by the front part of the body with original headlights, a modified shape of the hood and front fenders, new taillights with an insert between them, bumpers painted in body color, a trunk spoiler with an additional brake light, door moldings, door sill fairings, a new trunk lid with floor level connector. New efficient lighting technology is provided. The modernization has noticeably improved, modernized the appearance of the car, and also improved the aerodynamics of the car.

The interior of the VAZ-2115 car has become more comfortable, a new, more convenient and advanced instrument panel has appeared, which has a more streamlined and ergonomic shape, backlit push-button switches and indicator lamps (the so-called “European panel”), an adjustable steering column, a steering wheel from the “tenth” "family, "console" between the front seats. The new heater design provides efficient heating of the interior. The standard equipment includes an on-board driver warning system for closing the door locks, unfastened seat belts, leaving the ignition key in the lock, the level of oil and coolant in the engine, and extreme wear of the brake pads. The luggage compartment has become more spacious and convenient due to the increase in the trunk lid. The power units are similar to the VAZ-21099.

The cars use 1.5-liter gasoline engines, both carburetor and with an electronic fuel injection control system with a 5-speed manual gearbox. Initially, modifications with a carburetor engine were produced. In 2001, a modification of the VAZ 2115i was released with an injection (VAZ 2111) engine with distributed fuel injection. To increase service life and reduce noise at idle, a new clutch driven disc with an idle damper is provided.

What is under the hood of the VAZ 2114

Under the hood of the VAZ 2114 its key mechanisms are located. First of all, this is an engine - four-cylinder, single-row, with 8 or 16 valves. From the receiver, compressed air enters it and passes through the air filter (to the right of the engine).

In addition, under the hood of the 2114 there are:

1. The windshield washer reservoir is to the left of the engine.
2. The hydraulic tank for the brake system is just above the air filter.
3. The battery is in the lower right corner.
4. The cooling system expansion tank is on the right, above the battery.
5. Fuel system adsorber - between the hydraulic drive reservoir and the expansion tank of the cooling system.
6. The gearbox is under the engine, on the right side.

The adsorber on the VAZ 2114 appeared in order to comply with Euro-2 and Euro-3 environmental standards. It is designed to capture spent fuel vapors that have not liquefied. With the help of an adsorbent (usually activated carbon), the vapors are absorbed. A malfunction of the device is indicated by a characteristic hissing sound when opening the fuel tank, and a drop in engine speed at idle.

Symptoms of malfunction

The malfunction of the water pump on the four can be determined by characteristic symptoms or a combination of them. Most often this is evidenced by:

1. Coolant smell in the cabin. This symptom may indicate a pump failure. But the characteristic “amber” can also occur with other malfunctions.
2. Frequent overheating of the motor. The vehicle's dashboard will indicate that the engine temperature is too high. Under normal conditions, it should not exceed 90 degrees.
3. Uneven or regular wear on the timing belt. The crankshaft pulley may also look very worn.

4. Coolant leak near the pump and timing belt. Traces of this liquid may be visible in the engine compartment and under the car. It is worth noting that sometimes the problem occurs when the oil seal wears out or is installed incorrectly.
5. Pump noise and vibration. Unpleasant sounds are heard from under the hood when the engine is running. This symptom does not always indicate a failure of this part; it can also be caused by other reasons.

The appearance of one or more of the above symptoms or a combination of them is a reason to immediately check the pump. After all, its breakdown is very dangerous. As a result, the timing belt may break and, as a result, the valves and pistons of the engine will meet if the pistons are installed without recesses. The motor will jam. And only expensive and complex repairs will help restore its functionality.

The service life of the part for this AvtoVAZ model is about 100,000 km. But sometimes it can break even earlier. Therefore, on long runs, it is recommended to regularly monitor its operation.

Adjusting the hood latch is easy to do with your own hands

Let's take a closer look at the hood of our car

Has there been any strangeness in his behavior? Often we do not pay attention to such little things as the fact that the hood has become a little worse to close, more and more effort is required each time to open it, and a rattling noise has appeared (at first light and intermittent). After all, all this happens gradually, and therefore imperceptibly

We forget about such a simple matter as adjusting the hood latch.

Timely diagnosis is the key to safety

We notice a flat tire or a “sick” starter immediately and take urgent measures to eliminate the problem. And a tired hood lock, according to most car enthusiasts, “does not affect speed.” Indeed, it does not affect, but many are terribly annoyed by repeated clapping, nervously tugging at the handle in the hope that Sesame will finally open. And all this happens, as a rule, at the most inopportune moments. It seems like a small thing, but an irritated driver is a threat on the road, and for absolutely all road users.

Or a hood that opens of its own accord while driving... Even at low speed this can create serious problems.

Let’s not put off such a “trifle” as adjustment. Moreover, all operations can be performed independently, without resorting to the help of service station workers, and most importantly, completely free of charge!

And this happens sometimes!

What does the price depend on?

Motorists who need engine overhaul of a VAZ-2114 are faced with different prices for such a service. The cost depends on the influence of factors:

• Engine capacity.
• The prestige of the service company, its pricing policy.
• Urgency.
• Scope of work.
• Difficulty of repair.
• The need for a specialist to visit.
• Cost of spare parts.
• Equipment used.
• Automotive technician qualification level.

The more work is required to restore the engine of a VAZ-2114 car, the more expensive the service of a specialist will cost. You will have to pay extra for urgency and a specialist visit.

How to change the engine on a VAZ 2114

The VAZ 2114 engine changed throughout the entire production period of this car. The first models of the VAZ 2114 or “Samara-2” (as it began to be called by analogy with its predecessor) rolled off the production line with an engine from the VAZ 2109. It was an eight-valve injection engine with a relatively small volume - only one and a half liters. This engine did not differ in terms of developed power, which was 78 horsepower.

Since 2007, VAZ 21114 engines began to be installed on cars, with an increased volume of 1.596 liters and a maximum power of 80-84 hp. With. This engine complied with the Euro-3 environmental standard.

And since 2010, a model with a 16-valve engine has been produced. It's also a four-cylinder engine, but instead of two valves per cylinder there are four. The 16-valve engine has more power - 98 horsepower, faster acceleration, but is more susceptible to breakdowns than the eight-valve engine.

Thus, under the hood of the VAZ 2114 there are key mechanisms, the main one of which is the engine. Its operation is based on a distributed fuel injection system, which is regulated by an electronic control unit.

The VAZ-2114 car uses a hidden engine cooling circuit with an injector. It is highly complex and includes 28 elements. Traditionally, the assembly of the cooling system of this car is not of high quality. Therefore, throughout the entire period of operation, it requires constant monitoring, regular maintenance and repair. In this regard, many owners of this car are interested in the nuances associated with independent maintenance, repair and operation of the cooling system, among which the most common questions are:

1. 1. How to properly replace the coolant mixture?
2. 2. How to flush the cooling system?
3. 3. How to remove air from the VAZ-2114 cooling system?
4. 4. How to properly replace the cooling system pipes?

How to ensure ease of opening and reliable fixation?

For these purposes, a special part is sold that can be installed on the car yourself. This part is called a gas stop. They replace the standard rack and, as a result, the consumer properties of the car increase sharply. The opening of the hood begins as follows. You only need to lift the hood a little with one hand. Next, the gas stop gets to work. He himself will raise the hood to the required height and securely fix it there. The standard stop will no longer be used. During operation, this stop does not require any maintenance.

Many owners of VAZ 2114 cars prefer to install a gas strut on their car, especially since the installation process does not require much effort. To perform this operation you will need:

• The stops themselves;
• Two keys for 13;
• Four nuts with washers for 13mm;
• Drill;
• Eight-millimeter drill;
• A little enamel and bitumen.

In this case, the internal distance between the two holes will be 310 millimeters. The holes will be drilled into the thickening of the hood, inside of which there is a void. Nevertheless, the procedure should be approached with all responsibility, because if you overdo it, you can drill a hole in the hood itself. After making sure that everything is marked correctly, we proceed directly to drilling. Using a drill you need to make four holes. Two in the hood thickening and two under the hood, one on each side of the body cross member. To prevent the possibility of corrosion, it is advisable to treat the resulting holes with an anti-corrosion compound and paint. After this, you can proceed directly to the installation. We take the gas stop and install it in the drilled holes on one side. We do the same with the second emphasis. They will need to be screwed. For those who work without an assistant, it is better to first screw the stops onto the hood, and only then onto the body. If there is someone nearby who can support the hood, then the sequence of actions does not really matter. When everything is done, it will be possible to test the set stops in action. You will need to try opening and closing the hood several times. It should open easily and smoothly, and closing should not be accompanied by significant effort.

What do the tidy indicators do?

The control panel on the VAZ 2115 is located in the center console directly in front of the driver.
Descriptions of instrument cluster symbols are given below:

1. Coolant temperature sensor, if the controller arrow moves into the red zone, this indicates that the power unit is overheating.
2. A tachometer informs the driver about the crankshaft rotation speed; if the arrow falls into the red zone, it is necessary to reduce the engine speed.
3. Left turn signal.
4. Right turn signal.
5. A speedometer that tells you how fast a vehicle is moving.
6. Fuel level sensor in the tank.
7. The light indicator, made in the form of a gas pump, usually lights up if there is no more than 7 liters of fuel left in the gas tank.
8. Optics indicator, activated when the side lights are turned on.

Immediately after purchasing a car

So, you have become the happy owner of your own car, moreover, not a used one, but a brand new one, which brings much more positive emotions than buying a used foreign car at the same price. First of all, you should pay attention to anticorrosive. The bottom of the car and wheel arches come out of the factory without protection, so either contact a service station or take the time to buy plastic protection and a can of bitumen mastic. But you should not blindly trust the service station; always check the quality of the service provided.

new VAZ 2114 cars

After you have dealt with the car body, you should take up the wrenches and check the tightness of the nuts and bolts, at least those that can be obtained without unnecessary difficulties. The fact is that the domestic manufacturer has such a sin as loose bolts and nuts, which create unpleasant rattling noises.

Run-in

Warming up a new engine is a very important stage, and it is not necessary to wait until the temperature reaches operating 80 degrees; it will be enough to overcome the lower limit of 40 0 ​​C. If the car has not yet been run-in, then be sure to monitor the speed and do not load it with sudden accelerations, especially in a cold state.

During the break-in process, the engine pistons undergo final grinding, and if the engine is not warmed up, then as a result, not all elements will go through the thermal expansion phase, which will lead either to their rapid, uneven wear or to engine seizure.

Signs of breakdown

If, when you turn the ignition key, the electric starter does not spin, but you can hear soft clicks of the relay contacts operating, then the cause of the car malfunction is the starter. You can verify this by connecting it directly to the battery, bypassing this electric relay. If clicks are not heard, and the starter is working properly, then it’s time to change it.
