VAZ-2112 (16 valves). Repair and maintenance, owner reviews

VAZ-2112 was the last in the line of the 10th model. It is a modern and dynamic machine, in which operational as well as external indicators have significantly improved. It is worth saying that this is the best-selling car. Buyers are attracted by low prices, excellent maintainability, and also high practicality.

History of the model

The tenth family of front-wheel drive models of the Volga plant began in 1995, with the model 2110 with a sedan. Then in 1998, the factory launched the assembly of the station wagon - 2111. In the 99th the plant began to produce hatchbacks.

In the first years of production for the 2110 used a 1.5-liter sixteen-valve engine. At that time it was the maximum capacity of the plant.

In 2000, the plant introduced a new version of the hatchback - VAZ-2112, 16 valves. In comparison with the ordinary eight-valve version, the car had more power and more dynamism. The model immediately won the motorists, its appearance was sporty.

Packages

The car was manufactured and offered in the "Lux" and "Norma" trim levels. "Norma" from the luxury version differs only in that there was no trip computer, fog lamps, a set of light-alloy wheels, headlight cleaning system.

"Norma" is equipped with electric window regulators for all four windows, central lock, remote boot opening, steering column with height adjustment, immobilizer.

What is most interesting, in none of the complete sets (how expensive they were) there is no air conditioner. By today's standards, this is quite a big minus, because of which drivers are increasingly looking towards used foreign cars.

Exterior view and body arrangement

As for the dimensions, the VAZ-2112 (16 valves) decreased by 93 mm in length. This change occurred in the region of the rear overhang. But the size of the wheelbase was not transformed. The length of the body was 4170 mm. A height of 1676 mm and a width of 1430 mm remained traditional for the "tenth" family. The top line on this body very smoothly turns into a rather short rear overhang and a large wing. This design allowed the developers to make the car more manageable.

If we compare this hatchback with more classic models of the VAZ, then it should be noted that the "twelve" has the best aerodynamic characteristics and modern appearance. The model is very popular with fans of tuning.

A fully galvanized body of "tens", which became very popular at the time, still undergoes corrosion. Many owners of new cars did not consider it necessary to perform anti-corrosion treatment. The bottom rusted very quickly to holes.

Interior and interior

In the interior VAZ-2112 (16 valves) - all the best from two brothers. Here, the best characteristics of the station wagon were combined. The backs of the rear seats are divided into two parts. Each of them can be folded. This significantly increases the volume of the trunk. And this is the only advantage. In the cabin all is more modest, than in any foreign cars of the same classes and the same years.

Owners say that there is little light in the cabin, and on the dashboard. All the panels seem to be perfectly assembled, but there's still something creaking somewhere. The central tunnel next to the handbrake is equipped with buttons for operating the window regulator - it is considered that it is not very convenient to use. For passengers at the rear there are no such options - in the basic configuration, even mechanical handles are not provided.

Another disadvantage, according to the owners of the VAZ-2112 (16 valves), is the total absence of any kind of sound insulation. When driving with music on, you can clearly hear how the engine and the hydraulic booster work.

The big trouble is an incredibly tight block of pedals.

From the edge of the brake to the console - just over 10 cm. Many complain about this very narrow opening. In order to work with the gas pedal, you have to turn your leg sideways. And if you do not turn it off, then when the accelerator pedal is clamped, the brake is caught by the foot. In 2110 this is all right. Maybe the reason here is that the lining is made more convex? Maybe.

And the front seats are done well. They are additionally equipped with side support. But here everything is not so clear. Many complain about uncomfortable adjustments. But large people fit perfectly in the salon and in the driver's seat - this is a virtue, as there is not much room.

Another positive feature is the small height of the luggage compartment shelf. It is necessary to open the fifth door, and nothing prevents the loading.

In the car, good visibility. But the mirror in the cabin is not very comfortable to use because of the large racks and the tilt of the glass. Rear passengers also note excellent performance in this regard. But there is not enough space above the heads behind.

Chassis and steering

The main claim to running is excessive softness. It's all because of the redesigned suspension system. But many drivers do not have enough feedback. And while the machine is perfectly controlled. Turning the steering wheel slightly, you will immediately feel the result. By inertia, this hatchback surpasses both the sedan and the wagon many times. But rotating the steering wheel at low speeds is pretty hard. The fault in this completely falls on the hydraulic booster. It reduces effort, but the machine does not become more docile of it.

Driving characteristics are fairly confident. On the ice car is controlled. ABS here, of course, not. Brakes with vacuum amplifier and discs are in front, and rear are drum. Brake - and good.

The engine VAZ-2112 (16 valves)

As a power unit, the engineers used something new. They did not create the unit again, but on the basis of the motor 21083. It retained all the geometric characteristics of the 83rd, but at the same time it differs completely from it both in power and in other characteristics. In the development of it attended by eminent automotive brands. The engine is very economical. Among the minuses - a weak torque at low revs. Also, the owners write in the reviews of a weak belt drive, if the timing belt breaks.

VAZ-2112 (16 valves) has a displacement of 1.5 liters. The power he can give is 93 liters. from. The torque is 133 Nm at 3300 rpm. As for environmental standards, the motor is designed for Euro-3. Each cylinder has 2 valves. One - for the intake, the second - for the release.

Design Features

Four-stroke engine VAZ-2112 (injector 16 valves) differs in a row arrangement of the cylinder and piston group. The crankshaft in this unit is common for the two camshafts. Cooling system based on liquid, closed type. Circulation of cooling fluid of forced type. Lubrication system combined.

Block of cylinders, connecting rods, pistons

The VAZ-2112 engine (16 valves) is equipped with a block cast from high-strength cast iron. At first glance it seems that it is completely analogous to model 21083. But this is not so. The main difference is the smaller by 10 mm diameter of the head bolts. Other tides under the sensors of the injection system and other honing technology.

The connecting rods are made of steel by forging. They differ in the I-section. The same connecting rods can be found at 2110.

Pistons are steel, hollow, floating. The finger has a diameter of 22 mm. The length is 60.5 mm.

The VAZ-2112 head (16 valves)

This is a brand new cylinder head. It uses two camshafts. It was created with the support of specialists from the Porsche. So, the two shafts work from the gear drive. They are perfectly protected from dirt and dust. In the valve drive, hydraulic thrusters were used, and now there is no longer any need for manual valve adjustment.

Valve group

They are arranged in two rows V-shaped. Their design resembles the model 2110, however, the diameter of the plates and rods is reduced. Each valve has one spring.

VAZ-21124

Also on the "twelve" set unit 21124. Here the volume of 1.6 liters, power - 89 liters. With., The twisting moment - 131 Nanometers. The power system is also a distributed injection. The engine supports Euro-3 and Euro-4.

This engine is the continuation of the 2112 line. The volume was increased by means of a crankshaft with a large crank radius with the same cylinder diameter. The cylinder block here also has an increased height.

Here we were able to solve the problem of bending valves, and the characteristics are at the sports level.

Ignition system

The electronic module is used as the heart of the system. Motorists say a lot about the fact that it is quite problematic. It should be very carefully selected candles for him.

Ignition VAZ-2112 (16 valves) has two coils. One serves to work the first and fourth cylinders, the second - for the second and third. For problems in the module, the spark disappears in pairs. The system itself is not serviced or repaired. Control of it entirely is given to the controller.

There are several sensors in the system. This is a crankshaft position sensor that sends a signal to the computer, and then the "electronic intelligence" will calculate how to operate the coils. In the formation of the mixture and ignition, the detonation sensor familiar to many DMRV, cooling liquid, works . Other VAZ-2112 sensors (16 valves) are also working. For example, a throttle, oxygen, exhaust gas sensor.

Typical engine faults

Many motorists who own an "iron horse" with a motor 2112 complained about the deformation of the valves when the timing was broken. This is a typical malfunction. Repair is simple. You just need to change the pistons to those that stand on 21124. There the problem is solved, but as a payment for it the power will decrease. If you do not want to lose in this indicator, you need to constantly monitor the belt. Listen to the sounds. First the clips are squeaking, then rustling.

In addition, the engine can trip. How to deal with this unpleasant phenomenon? Check the compression level, ignition module, wires. If the revs are floating, then you can suspect the throttle, the idle speed regulator, the crankshaft position sensors, the DMRV.

Mark one more malfunction. It can occur at idle and on the go. The motor with the change of gear sometimes stalls. Clean the throttle or its sensor.

If the unit does not start at all, then check the starter and the battery.

Also, the ignition or power system may be jammed.

With proper care of this engine car VAZ-2112 (16 valves) repair is not needed. Just follow the manufacturer's regulations and regularly conduct maintenance. All instructions on basic operations will not cause difficulties.

Price list

At the very beginning, this hatchback was asked for more than for other models. It was considered quite expensive. Perhaps, the reason for this - electric windows and a lock. However, a little later prices fell, and equipment and equipment became richer.

To date, the average car VAZ-2112 (16 valves), the price is from 90 to 250 thousand rubles, depending on the configuration, tuning, engine. The car is suitable for various changes, so the owners modify it.

According to users' reviews, the most optimal cost is about 150 thousand rubles. Since at this level, it is by no means a trash.

So, we found out what the car VAZ-2112 has technical characteristics, price, reviews and bundling. Successful purchase!
