In detail: do-it-yourself vaz 21213 repair from a real master for the site my.housecope.com.
VAZ-2121 "Niva" is a four-seater off-road passenger car. Produced by the Volzhsky Automobile Plant.
The VAZ-2121 "Niva" car is a design development of JSC "AVTOVAZ". Produced since 1977. This is a vehicle for off-road driving, traveling to hard-to-reach places, hunting and fishing trips. The folding rear seat allows you to place and carry a variety of goods. The tailgate floor-level connector provides convenient loading and unloading.
"Niva" is a cross-country vehicle with a permanent non-disconnectable drive of all wheels with a center differential lock and a transfer case with a lowering row. The car had a very progressive design, combining excellent off-road qualities with the comfort of a passenger car, and had practically no analogues at that time. It has been successfully exported to many countries. The car became one of the first representatives of the now so popular "parquet" SUVs.
Body - all-metal, load-bearing, three-door, equipped with seat belts. Front seats - with head restraints, adjustable in length and backrest tilt, recline forward. The rear seat folds down to increase the luggage compartment. On request, the car is equipped with an electrically heated rear window, a cleaner and a rear window washer.
Another feature of this unique machine was the use of passenger car assemblies. So, its engine was created on the basis of 2106, the gearbox and rear axle are also borrowed from this car. Despite this, the "Niva" has a cross-country ability, unique for such a machine.

The car was equipped with a 4-speed gearbox with synchronizers in forward gears, or a 5-speed gearbox. The transfer case is a two-stage one with a center differential with forced locking. The cardan drive consists of an intermediate cardan shaft and cardan shafts for driving the front and rear axles.
The front suspension is independent, on transverse swinging arms, with coil springs, hydraulic shock absorbers and an anti-roll bar. The rear suspension is dependent, with coil springs, hydraulic shock absorbers, four longitudinal and one transverse rods.
Since the start of production, modifications have been produced with an in-line four-cylinder carbureted gasoline engine with a volume of 1.6 liters. The modification 21211, which appeared later with a 1.3 liter engine, was not successful.
As a result of the modernization of 1993, a new model "Taiga" was born, which was assigned the index "VAZ-21213". This is a four-seater off-road passenger car with permanent non-disconnectable all-wheel drive. It's hard to believe that there are 16 years between these modifications. During these years, the plant made almost no changes to the design of the 2121. And the changes made in the 21213 model are more cosmetic than technical.
Externally, the new car is distinguished by a modified rear part of the body. 21213 has a "long" third door to the bumper and new taillights. It has become much easier to load anything into the luggage compartment. The lock disappeared from the back door, which was constantly clogged with dirt. It can only be opened from the salon. True, the location of the handle that opens the trunk under the elbow of the rear left passenger is difficult to call successful: you have to act “by touch”. The bumpers are now painted light gray, which is more practical than the old unpainted aluminum.
The cabin has a new panel, new seats, new facings. The instrument panel is the same as that of the VAZ-21083 model. Only now the glare from it illuminates the windshield at night. The new seats are also made in the image and likeness of the "eight". They are more comfortable and more modern than the previous ones. But the mechanism, which folds the backrest for the passage of the rear passenger and moves the seat forward, is not reliable - after fifty operations it fails, due to distortions that have appeared, the back does not want to get into place. The rear plastic panels creak and squeak from light pressure. But now there is a pocket in the sidewall next to the left rear passenger.
The engine has been updated too. The working volume is increased to 1700 cm. A contactless ignition system and a Solex carburetor are used. An invisible but very significant improvement is the new shape of the combustion chamber. Modification of the engine along with changes in the transmission allowed to significantly reduce fuel consumption.
The transmission of the new car has a five-speed gearbox and main gears with a gear ratio of 3.9. Reinforced crosspieces are used. Their size changed and grease fittings appeared. In the transfer case drive - CV joint. Its purpose is to reduce vibration and transmission noise.
The brake system uses a vacuum booster and a master cylinder from the "eight". The effort on the pedals has decreased, but the wheel now lies "upside down" and nothing can be put into it. In addition, the procedure for adjusting the steering gear has become incredibly complicated - now you can only crawl up to it with a crooked screwdriver. The exhaust system has new mufflers. Their bodies are not welded, but rolled, like those of the machines of the “eighth” family.
For the external market, a modification of the VAZ-21214 with central fuel injection was produced. In the "standard" version - VAZ-21214-00. This car is a design development of JSC "AVTOVAZ" with a permanent non-disconnectable drive of all wheels with a center differential lock and a transfer case with a lowering row.
The model range of JSC AVTOVAZ also included the temporarily produced transitional modification 21219 - a combination of the old body 2121 and the engine with transmission 21213. On request, the cars can be equipped with a 1.9-liter Peugeot diesel engine (VAZ-21215).
Despite the fact that the VAZ-21213 is considered one of the most successful developments of the Volga Automobile Plant, like all mechanisms, it is prone to breakdowns. Moreover, the more mileage a car has, the more actively it begins to break down - this is characteristic not only of the Niva, but also of all other representatives of the domestic auto industry. Therefore, a dilemma very quickly arises - to constantly contact service centers or to learn how to repair VAZ 21213 with your own hands. With sufficient skills and "straight" hands, the latter is not as difficult to do as it seems - the main thing is to have all the necessary tools and accessories at hand.
The most common breakdowns and malfunctions
The most common malfunctions after which a VAZ 21213 Niva repair is required are:
Clogged carburetor;
Overheating of the engine;
Failure of timing chain tensioners and dampers;
Wear of the elastic clutch of the flush shaft;
Failure of the checkpoint;
Increased vibration;
Wear of CV joints anthers;
Oxidation of electrical wiring contacts;
Stove tap leak;
Body corrosion.
Some of the faults can be eliminated by yourself. For example, you can also clean the terminals from oxidation or install a new boot on the CV joint in your garage. With certain skills, you can also clean the radiator. But it is better to eliminate more serious problems with specialists - here you need certain knowledge, tools and equipment.
The main disease of the VAZ-21213 engine is the carburetor.When using low quality fuel - and such a problem occurs at our gas stations regularly - the carburetor is constantly clogged. If fuel lines and filters are clogged, simply clean them and install new filters if necessary. But if you do not pay attention to this problem for a long time, then very soon the fuel pump will fail and then you will have to change it.
Another problem, and almost impossible to eliminate, is engine overheating. The reason for this is the unsuccessful design of the cooling system, or rather the blowing system. This is especially noticeable on engines that have undergone overhaul, since due to cylinder bore, the baffle becomes thinner and heat transfer increases. You can fight it only by upgrading the airflow system and installing either an additional fan, or replacing it with a more efficient one. But it is impossible not to pay attention to this problem - even novice motorists know what long-term engine overheating is fraught with.
Another problem that requires a VAZ 21213 repair is vibration. Its cause is the failure of one of the transmission elements. There may be several reasons for this:
Violation of the centering of the transfer case;
Souring of the propeller shaft cross;
Biting the SHRUS promval;
Wear of the elastic clutch of the flush shaft;
Failure of suspension elements.
As long as all transmission and chassis assemblies are adjusted, vibrations are invisible. But it is worth at least one of the parts to fail - it is immediately felt.
Among other things, the VAZ-21213 has a characteristic disease - a failure of the fifth gear gears. The fact is that this box is a modernized version of the old four-speed gearbox. There is a big flaw here - the ill-conceived design of the lubrication system leads to oil starvation of the fifth gears and they wear out much faster than others - literally after 30-40 thousand kilometers.
There is a joke that the Niva's body begins to rust even before it is bought. This is, of course, an exaggeration, but with the anti-corrosion treatment of metal it is simply a disaster - it really starts to rust very quickly, especially in those places where there is active contact with water: sills, rear door, bumper attachment points, fenders, and so on.
In order to delay the appearance of holes in the body to the maximum, it is necessary to carry out anti-corrosion treatment every year. Considering how we struggle with road icing in winter, the bottom can burn out in literally a year, if it is not processed.
Also, pay close attention to the drainage and ventilation holes - if they become clogged, then moisture and condensation begins to accumulate inside.
If you can repair the VAZ 21213 with your own hands, then reinforce the floor with an additional metal plate in the place where the distributor is attached - due to increased vibration, this area is subject to increased loads and can simply fall off.

At the beginning of the 3rd millennium, the most significant events of the last century were summed up and named. The rapid development of VAZ-21214 vehicles did not pass by. Having gained fame at the end of the nineteenth century and at the beginning of the twentieth, while remaining something special today, the machine has become a loyal friend and indispensable assistant to many people not only in Russia, but throughout the world.
In the polls of magazines and newspapers about the best car of the century, a considerable percentage of votes were given to the VAZ-21214 "Niva" car, as it is advanced and unique. Many experts are surprised how the creators of "Niva" managed to collect so many positive qualities in one design at the same time.
This car is considered an SUV that combines good comfort, easy handling and high speed performance. The main advantage of this car is its amazing cross-country ability. In this "Niva" can not only surpass, but even catch up with the world famous car brands!
The VAZ-21214 car first entered the road surface in 1977, and since then world leaders have been trying to somehow catch up with it in terms of performance.
VAZ-21214 "Niva" is produced in a 3-door or 5-door station wagon body. The manufacturer provides a guarantee of flawless work, for the period of which the operation of the car will bring only joy. Any repair of this vehicle within 2 years or until it reaches 35 thousand kilometers is undertaken by the plant.
The car is equipped with a four-cylinder eight-valve petrol four-stroke engine with a volume of 1,690 cm / cu. The power unit is capable of reaching 83 hp. With. at 5 thousand rpm. The engine is designed according to the Euro-4 type, has electronic distributed fuel injection with an octane rating of at least 95. The engine has a single-disk, dry-type clutch with a hydraulic drive. The fuel consumption of the VAZ-21214 per hundred kilometers is declared to be 11.1 liters in the city and 8.3 liters on the highway. Up to 100 km per hour "Niva" is capable of accelerating in 17 seconds.
The car is equipped with a 5-speed manual transmission. The transfer case is installed with a lockable center differential. Permanent drive of full type.
With prolonged operation, the VAZ-21214 car, like any other, sometimes requires repair.
Based on the feedback from the owners who repaired their Niva on their own, we have compiled for you a list of the most common malfunctions and breakdowns requiring repair in the VAZ-21214 car.
Engine. One of the problem areas of the Niva engine are hydraulic lifters. When repairing this breakdown, it is necessary to clamp them correctly. With an incorrect tightening, various extraneous sounds and knocking appear. After a run of 100 thousand kilometers, the chain can stretch, which is manifested in the thundering sound that it makes.
Transmission. Frequent transmission breakdowns requiring repair occur due to wear of parts, which subsequently leads to the breakdown of an entire unit. To determine the presence of a malfunction requiring repair of the gearbox, various noise appearing during the operation of its elements helps.
The crosses must be lubricated every 10 thousand kilometers. In cars produced in 2005-2009, a cardan defect was noticed - vibration begins during movement. In this case, it is impossible to carry out repairs on your own, without qualified craftsmen and a service station.
Chassis. During the operation of the VAZ-21214, there are cases when moisture gets into the bearings, due to which the lubricants lose their properties. It is recommended to re-lubricate after 20 thousand kilometers. Malfunctions requiring repair and replacement of bearings cannot be diagnosed by oneself.
It is worth noting that there were no problems with the axle shafts in Niva cars, but when they are removed, some difficulties appear, namely, the bearing cannot be removed. If you are repairing this part, it is recommended to warm up the bearing before removing.
Brake system. The brakes in the VAZ-21214 car can boast of their reliability, they actually do not need repairs. The service life of the brake cylinders is 100 thousand kilometers, and the brake master cylinder does not require replacement even after 500 thousand kilometers.
Electrical and electrical equipment. When the air temperature drops below zero, the heating system fan may start squeaking. When squeaking sounds appear, repairs should be carried out, namely, the fan engine should be replaced.
The fuel level in the tank of a VAZ-21214 car may not be displayed correctly. The reason for this must be sought in the failure of the thrust ring of the fuel pump gasket on the float, due to which the level of the remaining fuel is displayed incorrectly. To carry out repairs, you should disassemble the interior trim and get the fuel pump.
Body.There are jokes around the world that the body of the Niva rusted even before the purchase. Of course, this is not true, but the solution to this issue at the plant was not treated well enough. The body of the VAZ-21214 car really rusts very quickly, in particular, in places of close contact with moisture: the back door, sills, fenders, bumpers and so on.
To avoid the early appearance of rust holes on the body as much as possible, it is advised to treat the body with anti-corrosion agents annually. Considering what measures are used in Russia to combat icing on the roads, the bottom of the VAZ-21214 can rot in a year.
Also, ventilation and drainage channels require special attention - if they become clogged, liquid will accumulate in them.
If you are able to repair the VAZ-21214 with your own hands, then it is worth reinforcing the floor with an additional metal plate in those places where the distributor is attached - due to high vibration, these parts experience increased loads and may simply fall off.
