VAZ 21074: model overview
Content
"Volzhsky Automobile Plant" in its history has produced many different models of cars. One of the classic versions of the VAZ is 21075, equipped with a carburetor engine. This model has not been produced since 2012, but is still in active use by connoisseurs of the domestic auto industry.
VAZ 21074 carburetor - model overview
The "seventh" VAZ series left the factory assembly line in 1982. "Seven" was a "luxury" version of the previous model VAZ 2105, which, in turn, was developed on the basis of the Fiat 124. That is, we can say that the roots of the domestic automotive industry go to the Italian auto industry.
In the spring of 2017, the Avtostat analytical agency found that the most popular sedan in Russia is the VAZ 2107 and all its modifications. At the time of the study, more than 1,75 million Russians used a car.
Where are the body number and engine number
Any car produced at the Volga Automobile Plant is required to receive several identification numbers. So, the most important of them are the body number and engine number.
The engine number is a kind of passport for a specific model, because it can be used to identify the car and trace the entire history of the “four” from the very beginning. The engine number on the VAZ 21074 is stamped on the left wall of the cylinder block, immediately below the distributor.
All other passport data of the car can be found on the aluminum plate located on the bottom shelf of the air intake box. Here are the following options:
- model name;
- body number (individual for each VAZ);
- power unit model;
- information on the mass of the vehicle;
- version of the machine (complete set);
- marking of the main spare parts.
Unfortunately, or maybe fortunately, this car was discontinued and you can only buy it in the secondary market. There are no specific kits. This car is quite popular for tuning, car owners understand that their cars are very far from ideal and make them either retro or racing style. My car was bought for 45 rubles for the same amount and was sold. But whatever it was, only positive memories remained in my memory.

Vehicle Specifications
VAZ 21074 is made in a sedan body - both according to the designers of the plant and according to motorists, a sedan is the most convenient "box" for both personal use and for cargo transportation.
It should be noted that the carrying capacity of the machine, indicated in the technical documents (1430 kg), is underestimated. Surely you have seen more than once the “four” loaded to the maximum, on which the neighbors were transporting things or sacks of potatoes. Until now, in any market, a fairly large number of sellers use the VAZ 21074 to transport goods. Do not forget that initially the model was not created for the transport of goods in principle!

The resource of the carburetor engine is relatively large - from 150 to 200 thousand kilometers. On the VAZ 21074, the repair of the power unit and the carburetor mechanism is not considered a costly procedure, since all components and parts are made according to the most simplified schemes.
Salon Description
By modern standards, the exterior of the VAZ 21074 is outdated.
It is difficult to talk about appearance, because in fact the car is very outdated and looks like a rarity in the city. But in any case, from a certain angle, we can say that it seems not terrible. In a word, classicism.
Due to the fact that the entire line of the VAZ 2107 family (and the VAZ 21074 is no exception here) is rear-wheel drive, the engine is located in front, which made it possible to significantly expand the cabin space: both in the ceiling and in the legs for the driver and front row passenger.
The upholstery is made of special plastic alloys, which do not give glare and are unpretentious in care. The floor of the car is covered with polypropylene mats. The pillars from the body and the inner parts of the doors are sheathed with plastic of medium hardness, and are covered with capro-velour on top. The seats in most cars are upholstered in durable wear-resistant fabric - velutin.
It must also be said that in the VAZ 21074 a large number of “auxiliary” materials are used for interior decoration - various kinds of mastics, bitumen gaskets, felt pillows and lines. All these materials somehow come into contact with the upholstery (doors, bottom, seats) and protect the interior from excessive noise from the outside. Bitumen and mastic are mainly used in equipping the bottom of the car, while soft and textile materials are used in upholstery and trim. This equipment helps not only to make the presence of a person in the cabin more comfortable, but also solves a number of other problems:
- increased sound insulation of the cabin;
- minimization of vibration waves while driving;
- protection of metal from rust;
- increasing the thermal insulation of the cabin.
Dashboard
VAZ 21074 is considered a more comfortable version of the VAZ 2107. Comfort is achieved in various ways, including the simplification of driving. So, the instrument panel serves to ensure that the driver at any time can see the current data on both the ride and the state of his "iron horse".
On the VAZ 21074, the dashboard is made up of many elements, each of which shows the operation of a particular unit in the car. The panel is embedded in the torpedo of the car from the driver's side. All elements are under plastic glass: on the one hand, they are clearly visible, on the other hand, the devices will be protected from possible mechanical shocks.
The following elements are located on the instrument panel of the VAZ 21074:
- The speedometer is a special mechanism that shows the current speed. The scale is numbered in divisions from 0 to 180, where each division is the speed in kilometers per hour.
- Tachometer - located to the left of the speedometer and serves so that the driver can see the speed of the crankshaft per minute.
- ECON fuel gauge.
- Engine temperature gauge - for the VAZ 21074, the operating temperature of the engine is set in the range of 91–95 degrees. If the pointer arrow "creeps" into the red zone of the device, the power unit is operating at the limit of its capabilities.
- The indicator of the amount of fuel in the gas tank.
- Accumulator charging. If the battery light comes on, the battery needs to be recharged (the battery is low).
In addition, additional lights and indicators are located on the instrument panel, which remain off in normal operation (for example, engine oil level, engine problems, high beam, etc.). Light bulbs turn on only when there is a malfunction of a particular system or when a certain option is turned on.
Gear shift diagram
The gearbox on the VAZ 21074 works according to the international standard. That is, the first four gears are switched on by analogy with writing the Russian letter "I": up, down, up, down, and the fifth - to the right and forward. Reverse gear is engaged to the right and back.

Some questions among drivers cause controversy. For example, when is it better to change gears on a car:
do not pay attention to the revolutions, look at the speed, the first one started, the second up to 40, the third at least up to 80 (the consumption will be high, better than 60), then the fourth, if the hill is ahead and you have 60 and the fourth, then it is better to switch to a lower speed select only when switching (at the moment the clutch pedal is released), so that it is smooth, without jerks, but in general marks have already been made on the speedometer) when to switch
The VAZ 21074 car is still actively used by motorists today. Despite the outdated design and limited functionality (compared to modern standards), the machine is very reliable in operation and durable. In addition, the simplicity of the design allows you to independently eliminate all breakdowns and not spend money on expensive services of after-sales services.
