VAZ-21045: technical specifications, photo

Among the classic domestic universal car models, the original VAZ-21045 modification remains one of the most popular models. The car is an exact copy of the famous "four", only with a diesel power unit. In favor of this model is shown by low loading height, body structure with the possibility of installing an additional trunk, as well as the price and fairly tolerable technical characteristics. With a diesel engine, the vehicle was produced in limited batches in three trim levels (standard, luxury and averaged performance).


With the release of the car VAZ-21045 the salon has completely changed, the car has become more comfortable and modern. Not only the exterior, but also the interior trim, the instrument panel were altered. The updated transmission with five stages has a mechanical drive.

It is worth noting that the VAZ-21045 diesel was not produced in large batches. At the same time, the car was in great demand, considering the needs and opportunities of that time. In appearance, petrol modifications and options for diesel fuel did not differ, it was extremely problematic to acquire a new model. Nevertheless, second-hand copies could be found at an affordable price. Despite all the shortcomings of the Soviet car industry, the determining factor in the popularity of this machine was its practicality and availability of spare parts. Even now, these "universals" are in great demand among rural residents.

Main technical characteristics

VAZ-21045 has the following technical indicators:

  • Body type - station wagon.
  • The number of doors is five.
  • Length / width / height - 4,11 / 1,62 / 1,44 meters.
  • The capacity of the trunk is 345 liters.
  • Own weight - 1.02 tons.
  • The main base is 2.42 meters.
  • The track (front / rear) is 1.36 / 1.32 meters.
  • The clearance is 175 millimeters.

The serial production of the VAZ-21045 (diesel) vehicle continued from 1999 to 2006. The vehicle was equipped with a power unit with a capacity of fifty horsepower, the volume of one and a half thousand cubic centimeters. The transmission unit of the car consists of a single-disk dry clutch with a spring of the central-pressure type. Gearbox is a mechanical variation with five or four synchronous steps on all forward gears.

Brakes and steering

The disc-shaped wheels of the VAZ-21045 are equipped with 165/70 / 80R chamber radial tires . The independent front suspension has cylindrical springs with two pairs of longitudinal bars. The rear unit is equipped with five bars, a rigid beam and hydraulic shock absorbers.

The brake system of this vehicle in front is equipped with a pair of opposing disc cylinders and rear drum brakes with a pressure regulator. The clutch in the car is hydraulic, the parking brake is cable, the steering unit is safe with the intermediate propshaft.

The control gear reducer consists of a worm gear and a roller with a pair of crests, which are responsible for the gear ratio. The steering wheel includes two lateral symmetrical and one central link. Also available pendulum-pivoting levers and bipods.

Electrical equipment and operational parameters

At car VAZ-21045 technical characteristics in terms of electrical equipment have the following indicators:

  • Single-wire wiring system with a nominal voltage of twelve volts;
  • The battery corresponds to the class 6ST55P (capacity 55 ampere-hours in the discharge mode for at least twenty hours);
  • Alternator with regulator and rectifier;
  • The starter power is 1.3 kilowatts, there is an electric traction relay and a freewheel;
  • Type of spark plugs - А17ДВ or FE65P.

The maximum speed that the diesel VAZ-21045 develops is about 145 kilometers per hour. At the same time the machine spends from seven to ten liters of fuel for a hundred miles. The capacity of the fuel tank is 42 liters. With the capacity of the main trunk of 345 kilograms, it is possible to mount an additional compartment on the roof (50-60 kg).

The engine VAZ-21045 (diesel engine)

The characteristics of the powerplant of the car in question are as follows:

  • Type of motor - diesel with a turbocharger;
  • Working volume - 1,8 liters;
  • Rotational speed - 4600 rotations per minute;
  • Cylinder diameter / stroke - 82/84 millimeters.

VAZ-21045 with a diesel engine is an experimental technique in its time, which in the initial versions had a lot of shortcomings. However, the low price of the car and subsequent improvements made the car one of the most in demand in rural areas.

In many ways, such popularity is due to good driving performance, which is comparable with the "Niva" and further hybrids in combination with fuel economy, ease of maintenance and cheap parts.

Advantages of the power unit

Despite the apparent mediocrity, the VAZ-21045 engine proved to be quite good. In operation, the motor does not require constant cleaning of injectors and candles, provided it is refueled with high-quality fuel. In addition, it should be noted that the engine of this machine allows the owner to save on insurance and repairs. The benefit of spare parts and repair services is everywhere in the Russian Federation.

The machine runs perfectly at frosts over twenty-five degrees, if it is properly heated and do not hurry to start from the first time after turning the ignition key. For its modification, the VAZ-21045 engine fits perfectly into the concept of the whole unit. It should be taken into account that the car is still more designed for users from rural areas, in which it is not bad succeeded.

Weaknesses of the motor

The disadvantage of the engine is the weak gasket between the block and the head. Over time, the power plant begins to overheat, and bubbles appear in the expansion tank. It is not difficult to solve the depressurization, it is enough to replace the sealing element. This problem was inherited by the diesel engine of the VAZ-21045. This is due to the fact that such an aggregate needs its own cylinder head bolts (cylinder head), which the Quartet had unified with petrol versions of models with front-wheel drive. Often, the tightening force was insufficient, which led to the omission of the gasket.

The oil pump works for a long time, but in the bearing of the cooling system there is a regular play, which must be eliminated by replacing the element. It is worth noting that rarely the native pump fulfills the put resource. Contrary to the opinion that the fuel "Bosch" equipment could not withstand the domestic diesel fuel, it departed 125 thousand kilometers without comment.


The characteristics of the VAZ-21045 will continue to be studied in a practical example for testing the motor. As the tests have shown, the diesel consumes about 0.4 liters of engine oil per thousand kilometers, although the manual stipulates a limit of 0.6, which is not so little. After five thousand runs, the filter element is already bathed in oil. Developers have eliminated this problem by removing the ejection hose from the filter. This made it possible to keep the element longer in cleanliness and not to collect oil baths in the crankcase.

The crankshaft, liners, half-rings on the stops conscientiously work out the put resource in 125 thousand kilometers. It is worth noting that these parts VAZ-21045 still fit into the design dimensions of the motors, they can be safely used in the assembly of new power plants. The same can be said about the pushers and the camshaft. The head of the block of cylinders was spoiled by the picture that the guide sleeves were worn to the limit.

Owner feedback

Users of a fairly rare diesel modification VAZ-21045 note in it a lot of pleasant moments, but not without minuses. The pluses are attributed to pluses:

  • Multifunctional auto and high payload;
  • Reliability of the power unit and fuel injectors;
  • Economy (fuel consumption - about six liters per hundred kilometers);
  • Simplicity in repair and maintenance;
  • Good patency.

As for the shortcomings, here on the first place the following points:

  • High noise when the clutch pedal is depressed;
  • Insufficient ground clearance for driving on country roads;
  • Poor quality of some components;
  • Insufficient number of workshops for the repair of diesel engines from VAZ (but this is more a lack of service than cars).

In general, car 21045 with diesel engine left a good impression for domestic inexpensive equipment.

The result

The main advantage of the car in question is its economy, but at the same time the dynamics suffer when compared with the petrol analog. The power unit perfectly behaves on the move, does not require pumping, has a more even draft. At temperatures up to minus 20 degrees, the car starts without problems, the engine complies with the Euro 2 standards.

It is difficult to name the engine of the Quartet ideal, it requires structural improvements and improvements, but it is easy to maintain and repair. Now it is problematic to buy a diesel VAZ-21045, due to the small print run. It is assumed that these machines will produce Izhmash, but much depends on the demand for the goods.
