VAZ 2104 is an old-fashioned car. It can be repaired, including with your own hands. Some things are done even in a private garage, without serious experience. This is not like today's foreign cars, the repair of which consists of replacing units: the gearbox is broken - we change the box, the starter is broken - we change the starter, the car is broken - we change it... Not to that extent, of course, but close to it.

Repairing a VAZ 2104 is a “club” event. Members of the informal club “VAZ 2104 Repair” can do anything. In private garages, they disassemble the engine, grind the valves, upgrade the carburetor and increase engine power to 200 Horse power. Not everyone can do this, but even inexperienced car enthusiasts can do simple repairs on a VAZ 2104 with their own hands.

Which machine components most often require repair and why?

VAZ 2104 is a work car, not a ceremonial car. Many car owners are rural residents; they are often driven on bad roads or off-road conditions. This determines the character typical breakdowns VAZ 2104. Suspension parts often break.

To the number typical faults breakdowns include:

• ball joints;
• master brake cylinder;
• shock absorber struts;
• front brake cylinders;
• rear brake cylinders.

Car brakes are important from a driving safety point of view. Without adequate experience and infrastructure, brake repairs should be done by professionals. They do these jobs every day and are responsible for them. Such breakdowns of the VAZ 2104 happen often, and the technicians have a lot of experience.

The second place in the number of failures in the VAZ 2104 car is electrical equipment. Bulbs burn out, contacts come loose, breaks through high voltage wires. From time to time you have to change the battery and buy an alternator belt. Electrical engineering is the science of contacts. You have to keep an eye on them.

The VAZ 2104 engine is reliable, it has proven itself during operation in winter and summer. But he requires care. The fuel and air filters of the VAZ 2104 become clogged and must be changed at regular intervals. The VAZ 2104 engine does not like “left-handed” low-quality gasoline. Refuel your VAZ 2104 at trusted gas stations.

Clean fuel tank, fuel supply pipelines and carburetor VAZ 2104 - a labor-intensive and unpleasant task. The use of special fuel additives helps, but it is better to avoid the risk of filling with “left” gasoline.

Will the repair and operating manual help when disassembling a car?

The repair and operation manual for the VAZ 2104 car is an indispensable source of information about your car. Where else can you find out how much oil is poured into the VAZ 2104 engine and with what frequency and what oil is suitable for your “four”. The manual says how much luggage is loaded into the trunk of a VAZ 2104, what fuel consumption is used when driving in the city and on the highway, how much anti-freeze is poured into the washer reservoir windshield to what pressure the tires are inflated. This information is given in the section on operating the VAZ 2104. And the more accurately you follow the recommendations from this section, the less often you will have to refer to the repair section.

The VAZ 2104 wiring diagram contains a lot of information. The manual contains electrical diagram indicating the color of the wires that lead to electricity consumers, and the current ratings for which the fuses are designed. This information is indispensable when troubleshooting problems related to electrical repairs of a VAZ 2104 car.

It is important that the repair and operation manual that you purchased along with the car contains information specifically about your modification and configuration option of the VAZ 2104. Information obtained on the Internet often refers to a version of the VAZ 2104 that is different from yours and may not be suitable for you personally. If you rely on information obtained from the Internet, you are responsible for the result. If you find a typo in the official repair manual, you can submit a claim to the manufacturer of the VAZ 2104, and he will respond.

The official manual is important when disassembling and even more important when assembling the VAZ 2104.

Differences in the repair of carburetor and injection versions

From a repair point of view, the carburetor and injection versions of the VAZ 2104 engine differ in that:

• a carburetor engine is easier to repair in the field, but it breaks down more often;
• The VAZ 2104 injection engine fails less often, but it is more difficult to repair without the appropriate infrastructure.

The VAZ 2104 carburetor engine has a device familiar to product consumers domestic auto industry since pre-war times. The air-fuel mixture is prepared in the carburetor, enters the engine cylinder, ignites from the spark plug and pushes the piston. If the VAZ 2104 engine stalls while driving, if the speed idle move they float if the engine reacts sluggishly to pressing the accelerator pedal - there is only one recipe. I pulled the suction towards myself and off to repairs. Gasoline consumption will increase, but to the nearest auto repair shop on a VAZ 2104 with carburetor engine you will get there.

When an engine with multiport injection needs to be repaired, things are not so simple. Operating modes injection engine disposes of the electronic unit control unit (ECU). To understand what exactly is the problem that requires repair, you need computer diagnostics, reading error codes from the ECU. This is not the case on the road. Get the cable, ask for a trailer or call a tow truck.

Both versions of the VAZ 2104 engine have pros and cons. The trend in the global automobile industry is the transition from carburetor to injection engines. Our time is the time of the injector. So, compared to a carburetor engine, an injection engine has more advantages than disadvantages. And it's not just a matter of repairs.

Injection engines are more economical, reliable and environmentally friendly.

DIY electrical equipment repair

The most common type of repair of the electrical system of a VAZ 2104 car is replacing the fuse. If an electrical appliance fails, first check the fuse. Whether it's a light bulb, an actuator, or an indicator, start with the fuse.

On the VAZ 2104 in the first years of production, finger fuses were installed. They were dielectric cylinders with metal contacts at the ends and a fusible element inside the cylinder. The design was not very reliable. The contacts got hot and the fuses failed.

Subsequently, fork-type fuses were used on the VAZ 2104. This type of fuse is a plastic housing on which color and numerical marking rated current, and two contact flat electrodes connected to each other by a fusible jumper. Through the window in the upper part of the case you can see the condition of the fuse element.

The fuse box is located in engine compartment on the right side. The block is closed on top with a lid on which symbols for the purpose of the relay, fuse numbers and the circuits they protect are printed, which is convenient for repairs. Most of the circuits of the VAZ 2104 car are protected by fuses installed in the mounting block.

By removing the fuse that protects the circuit of the failed device, make sure that it has failed. Insert new one. It is not recommended to use “bugs” made from individual strands of stranded copper wire for repairs. Is it dangerous. Remember that replacing a fuse does not eliminate the cause of its blown and often only provides a temporary reprieve. After replacing the fuse, go to the workshop as soon as possible, determine the cause of the failure and make repairs.

A supply of fuses of three ratings for repairing a VAZ 2104 should accompany you on every trip.

DIY generator repair

A common type of repair of VAZ 2104 units is the elimination of breakdowns associated with the car’s generator. Malfunctions are divided into three groups.

1. Incorrect belt tension adjustment.
2. Belt failure.
3. Damage to the generator itself.

The belt in the VAZ 2104 engine passes through 3 pulleys: the generator itself, crankshaft and the coolant pump shaft. The correct belt tension can be checked by measuring the free deflection of the belt between the crankshaft and water pump pulleys. The deflection is measured with the engine not running, in the middle of the belt span between the pulleys. The standard value is 10–12 mm. If the deflection is higher than normal, repairs are necessary: ​​the belt is tightened.

You can do this kind of work yourself. To do this, loosen the nut securing the generator to the adjusting bar. Move it away from the engine crankcase until the belt tension is restored to normal.

For self-repair generator you will need:

• portable multimeter;
• three-jaw puller;
• a soft metal drift for pressing out the front and rear bearings;
• mandrel for pressing bearings;
• set of keys and screwdrivers.

During the repair, you will probably have to grind off the pierced ends of the bolts securing the front bearing cover with a grinder. You will need a fully equipped locksmith workshop. There are craftsmen who can rewind a burnt-out stator winding, but this is an activity for fans of VAZ 2104 repair. You will spend more money on the wire than on purchasing a used generator from disassembly. And you don’t need a new one: your car is “old,” well-worn. It's unlikely to survive the new generator.

Replacing a broken unit yourself is the maximum you can claim without professional experience and special equipment for repairs.

Then the VAZ-2104 was produced in Izhevsk and supplied to Ukrainian factories for large-unit assembly. Bogdan" and "KrASZ". When creating this model, the designers were faced with the task of achieving maximum consumer effect at the lowest cost. The first samples of the Quartet were not even equipped rear wiper and heated glass.

Note that there was even an export version VAZ-2104.

A later version of the VAZ-21047 was equipped with a five-speed gearbox, partial power accessories and an interior with anatomical front seats from VAZ-2107. And from 1999 to 2006, even a modification of the VAZ 21045 with a diesel engine was produced power plant volume 1.52 liters. The “four” has a roomy interior; moreover, the useful volume of the trunk is increased due to the folding rear seat. Despite the outdated design, the car is simple and reliable in operation, as well as an affordable price.

The VAZ-2104 is perfectly suited for transporting both cargo and passengers. A connector back door along the floor line does not create unnecessary inconvenience during loading or unloading. The car is perfect for long journeys and for trips around the city.
