Body structure
Replenishment of the VAZ family of cars occurred in 1980. It was then that the first car of the so-called 2nd generation appeared, namely. The car is rear-wheel drive, has 5 doors and a sedan body type. Currently, there are few fans of such a specimen left, but this model has not yet been forgotten. It is still used today, since the VAZ 2105 is a real draft horse and often helps in work.
Operating this car is a little different from using modern cars, and it is a little more difficult to drive compared to the latest models. If you have such a machine, you should carefully study its repair manual.
It should be said that the car is quite durable, and some breakdowns can be easily fixed with your own hands. We list the main faults that can lead to repair of the VAZ 2105.
Basic faults
- The engine does not start. In this case, several options for eliminating the breakdown are possible. The first thing you need to do is check the presence of fuel in the . If there is fuel, you should carefully examine the fuel pump. It may become clogged or be completely faulty. If everything is fine with the pump, pay attention to the ignition system. If there are no problems with it, then the reason is a leak in the carburetor.
- The engine runs unevenly or begins to stall at idle. There may be several reasons for this problem. These include: incorrect adjustment of the idle speed in the engine, malfunctions in the carburetor, damaged drain pipe, worn gaskets, damaged pipeline hose, incorrectly set gaps, breakdown of the ignition system.
- cannot develop full power. The reasons are as follows: the carburetor throttle valve is not fully open, the air filter is clogged, the ignition system is faulty. You need to check all these points to fix the problem.
These are the main malfunctions of the VAZ 2105 engine. It also does not hurt for a car enthusiast to remember how the car should be operated correctly.
At first, you should not use the maximum speed limit of the car. The driver needs to get used to driving the VAZ 2105. If you choose the wrong speed of the car when driving, you risk damaging the front suspension elements and causing the rear axle beam to bend. Also, at maximum driving speed, rapid tire wear is possible, and increased body vibration will lead to instability of the car.
General information about the car
Model VAZ-2105 Zhiguli/Lada Nova is a rear-wheel drive four-door five-seater sedan from AvtoVAZ.
In 1980, the first-born of the “second generation” of rear-wheel drive cars appeared - the VAZ 2105 sedan. The model appeared as a result of a rather serious modernization of the previously produced VAZ cars of the “classic” layout. Based on the 2105 model, a little later the “luxury” sedan VAZ 2107 and the station wagon VAZ 2104 appeared. These models, together with the 2105, eventually replaced the “first generation” models (with the exception of 2106).
The VAZ-2105 model in its design almost corresponded to the European fashion of the early 1980s. This allowed the model to be sold in a number of European countries for many years to come. Although in Europe such rear-wheel drive four-door five-seater sedans began to lose ground to front-wheel drive models already in the 70s. Since its appearance (and even more so now), this classic sedan has not become prestigious for many car owners and, accordingly, has not become AvtoVAZ’s most popular product. This did not prevent it from being considered the most progressive design before the advent of front-wheel drive VAZs. Externally, the car received straight lines of body design, large rectangular block headlights at the front and rear, aluminum bumpers, fenders with then fashionable cut contours, and the camshaft was driven by a belt rather than the usual chain. The ventilation system differs from the previous ones by the presence of rectangular deflectors. Electrically heated rear window is standard! The fuse and relay box is located in the engine compartment.
The VAZ-2105 model range, which is still produced, reflects the very essence of the modern concept - a vehicle. A somewhat ascetic interior can only spoil the first impression with the build quality and level of equipment, but not with the price (especially after devaluation)! The interior has undergone significant changes: a new instrument panel, new seats and door trim. The interior is not very large - it matches all Zhiguli cars, but new materials, front headrests and an acceptable driver's workplace (the driver's seat is moved back, which allows tall drivers to sit more comfortably behind the wheel) make a better impression than its predecessor - VAZ- 2101. However, as before, three people in the back seat are still a bit cramped. In some cars of the latest releases, the electrical wiring has been changed due to the installation of an instrument panel from the VAZ-2107 model. Due to the change and simplification of the electrical part, carried out almost annually by the manufacturer, when purchasing such models, it is necessary to consistently check the operation of ALL ELECTRICAL CONSUMERS!
From the start of production, the VAZ 2105 was equipped with carburetor engines with a displacement of 1.3 liters and a power of 64 hp. (with a camshaft belt drive), these cars were also equipped with 69-horsepower (according to the old GOST) VAZ-21011 engines, which until 1986 were equipped with oil filters of type 2101. Subsequently, they were replaced by compact ones of type 2105. The engines were constantly modernized. Later, a modification of the VAZ-21053 with a VAZ-2103 engine with a power of 72 hp was mastered. (according to the new GOST). For a long time, the VAZ-21051 was modified with a 1.2-liter VAZ-2101 engine with a power of 64 hp. (according to old GOST).
From 1982 to 1984, together with valve rocker arms made of 40X steel, the camshafts were nitrided to increase wear resistance instead of high-frequency hardening, which provided increased corrosion resistance, wear resistance and high resistance to alternating loads. Since 1985, camshafts have been installed with whitened cams. These shafts have a hexagonal belt between the third and fourth cams. From the same year, models were equipped with 45-liter fuel tanks for AI-93 gasoline without drain plugs instead of 39-liter gas tanks with drain plugs.
Carburetors type 2105 with a forced idle economizer (EFH), which allows reducing carbon monoxide emissions (the notorious CO) during engine braking and reducing fuel consumption, were installed on engines until 1985. Then they began installing carburetors of the 21051 type, which were simpler in design, which until 1987 were equipped with an econostat. Since 1986, instead of the ST-221 starter, a starter type 35.3708 and an additional ignition relay have been installed. The cooling system also changed. So, since 1988, “fives” (the informal name of the VAZ-2105 and modifications among drivers) have been equipped with radiators with aluminum cores made from two rows of horizontal aluminum round-section tubes and cooling plates. On sedans, in addition to four-speed gearboxes, since 1985, unified five-speed ones of the VAZ-2112 type, designed on their basis, and later - of the VAZ-21074 type, have been installed. With AvtoVAZ winding down the production of low-power 1.2- and 1.3-liter engine models, only the most powerful 1.5-liter modification of the VAZ-21053 remained in production, the configuration of which can differ significantly in interior trim (from leatherette to velor), etc. In addition It should be noted that VAZ 21054 cars are produced in small series for special orders of the State Traffic Safety Inspectorate, the Ministry of Internal Affairs, the FSB and other special services, which are additionally equipped with a second gas tank and a second battery.
VAZ-21057 (Lada Riva) - a model similar to the VAZ 21053, but with a right-hand steering column. The location of the control pedals and the vacuum brake booster has been changed accordingly. The windshield wiper movement algorithm has been changed. They move from left to right, which is due to the “mirror” wiper drive mechanism. This export modification is right-hand drive and 1.5 liter. engine was produced in 1992-1997 for the UK
Since 2001, a new model configuration program was adopted; two types of execution appeared for the VAZ 2105 model: “standard” and “norm”.
In general, second-generation rear-wheel drive Zhigulis are still in steady demand among the unspoiled domestic public, who are ready to forgive many assembly flaws and low-quality components for the cheapness and availability of spare parts. The handling of the “classic” on slippery winter roads has also long been below world requirements.

One of the most popular cars produced by the VAZ plant is the Zhiguli. five, namely VAZ 2105“Zhiguli”. This car rolled off the assembly line back in 1980. In terms of its format, the VAZ Five is a rear-wheel drive four-door sedan designed for five passengers. Later, based on this model, no less famous models appeared:
- VAZ-2107;
- VAZ-2104 station wagon.
The external exterior of the car was fully consistent with its time, namely the eighties. The body of the five consisted of straight lines, the bumper was made of aluminum, and voluminous rectangular headlights. There is no point in further describing the external data of the well-known five. Even after more than 30 years, this car remains recognizable and popular.
Initially, the VAZ-2107 was equipped with a 1.3 carburetor engine. But there were also engine configurations using oil filters, type 2101. The engines on this model were constantly modernized, making them more powerful and durable.
Technical characteristics of the VAZ-2105: the engine has a displacement of 1.3 and a power of 64 hp. The body exterior dimensions are as follows: length – 4130 mm, width – 1620 mm, height – 1446 mm. The ground clearance adapted to our off-road conditions is 17 centimeters. But the trunk does not have a large volume, only 385 liters. Combined cycle fuel consumption is about 10 liters per 100 km.
The VAZ-2105 model was also loved because it is quite easy to maintain. This allows you to do simple repairs and tuning yourself if possible.
Despite frequent repairs and the inability to meet the standards of modern automotive industry, the VAZ-2105 remains one of the most popular models. Not a high starting cost, ease of repair and maintenance, makes this model truly popular.
