But that’s not all, replacing the VAZ 21099 thermostat, as well as replacing the timing belt on the VAZ 21099, may be necessary after the next preventive inspection.
Other repair procedures are less common. But for them, the section also provides detailed manuals that take into account all the nuances necessary to avoid mistakes.
Main characteristics
First of all, the book repair and operation of a car tells the main characteristics of the car. The sedan body is made simply, but at the same time elegant. There are no plastic masks on the front fenders, unlike similar models. The 1.5 liter engine shows good technical characteristics. The gearbox is made manually with 5 steps. The injection engine consumes little fuel, about 7-8 liters per 100 kilometers.
For additional driver comfort, there is an on-board system that monitors errors. The windows are electronic and the doors are locked automatically. The seats guarantee comfortable seating for passengers and drivers.
Glass cleaners
Operating a vehicle with faulty wipers is prohibited. If the drive is working properly, but the quality of cleaning leaves much to be desired, replace the brushes immediately. This is an inexpensive consumable item, installation of which takes just a few minutes and does not require the use of specialized tools. Remember that in addition to comfort in bad weather, serviceable wipers significantly increase traffic safety, and timely replacement of the blades will help you avoid scratches on the windshield, which sometimes even expensive polishing cannot remove.
Also pay attention to the ability of the windshield wiper mechanism to operate at high speeds. As a rule, a decrease in their speed, regardless of the selected mode, indicates a malfunction in the drive
Auto highlight
First of all, you need to study the brake system. This includes regular replacement of pads and brake cylinders. The repair and operation manual for a VAZ 21099 carburetor or injector describes in detail how to disconnect the fasteners, dismantle the old part and install a new one.
The literature allows you to competently bleed the brake system. This is a simple action if you follow all the steps step by step:
- It is necessary to open the reservoir on the master cylinder.
- You should find and clean the bleeder fitting. It is located on one of the brakes, specifically for troubleshooting and prevention.
- Brake fluid is poured using a special hose. The cable is immersed in a bottle with it and the brake is pumped.
- The buddy must press the pedal all the way down several times and then hold it down.
- The fitting is unscrewed with a key, the liquid merges with the air.
For a more detailed description of the procedure, download the manual. This process is repeated several times until no more air bubbles come out.
Operation of the VAZ 21099 car
Exhaust gases are toxic! If you must start the engine in a garage or other building, provide good ventilation or be sure to open the gate.
When starting to repair or maintain electrical equipment, first be sure to disconnect the wire from the “-” terminal of the battery.
When coasting, do not turn off the ignition - the anti-theft device in the ignition switch may be activated, blocking the steering column shaft. Your car may become uncontrollable!
Leaded gasoline, antifreeze and antifreeze are toxic, so take precautions when filling your car with technical fluids. If a catalytic converter is installed in the exhaust system, please note that when the engine is running, it heats up to temperatures above 600 ° C
Therefore, to avoid a fire when parking, make sure that there is no dry grass or flammable materials under the bottom of the car.
If a catalytic converter is installed in the exhaust system, please note that when the engine is running, it heats up to temperatures above 600 °C. Therefore, to avoid a fire when parking, make sure that there is no dry grass or flammable materials under the bottom of the car.
It is prohibited to operate a vehicle with the emergency oil pressure lamp on: it should light up briefly (no more than 2 s) only when starting the engine.
Do not work under a jacked-up vehicle. Be sure to place supports under the body.
It is prohibited to smoke or use open flames when refueling or servicing the vehicle.
It is forbidden to check the operation of the generator by disconnecting the wires from the battery, as well as the functionality of the ignition system “for spark”.
When lifting the car with a jack, be sure to apply the parking brake and place suitable supports under the wheels on the opposite side.
Maintenance and repair of the car during the warranty period must be carried out only at service stations with a mandatory note about the work in the service book coupons, otherwise you will lose the warranty on the car.
Before driving, warm up the engine at idle speed, since running a cold engine at high speeds will reduce its service life.
When turning on the starter, the gearshift lever must be in the neutral position.
Drive away only in first gear.
Do not exceed the load capacity standards specified in the technical specifications of the vehicle: overload leads to increased wear of tires and suspension parts, as well as loss of directional stability.
Check the air pressure in your tires regularly: low pressure leads to increased tire wear. A difference in tire pressure of 0.2–0.3 atm leads to a deterioration in vehicle handling.
Vehicles equipped with catalytic converters cannot be fueled with leaded gasoline. This will lead to rapid failure of the neutralizer.
Regularly check the condition of the protective covers of the steering rack, constant velocity joints (CV joints), ball joints, and steering rod joints. Damaged covers must be replaced, as water and dirt will quickly damage the mechanisms.
For refueling, use fuels, lubricants and operating fluids recommended by the manufacturer.
Regularly check the condition of the battery terminals and the fastening of the wires on them. Loose or oxidized terminals can damage the vehicle's electronic devices.

Heart examination
Any edition of the manual says that the most important part is the engine. The driver knows that each vehicle has its own resource. In this case we are talking about 150 thousand kilometers. In most cases, the machine lasts longer, but proper care is important for this.
First of all, you must follow the maintenance rules. The manual provides detailed advice on when and how to change each part. You can handle almost all consumables with your own hands.
The second point is driving style. The engine is strictly prohibited from operating for a long time at low or high speeds. The driver should change gears in a timely manner.
Recommendations include restrictions on towing, cold starts, and the use of poor fuel.
The main way to extend the life of the machine's heart is to maintain it regularly. It consists of a planned replacement of technical fluids and consumables. Depending on the mileage, but on average approximately once a year, it is necessary to inspect the car and consult the manual for preventative repairs and identification of problems.
1) Warning icons on the dashboard: "Check Engine" indicator
The check engine light on the dashboard is the most common problem for car and truck owners. This light on the dash comes on when the ECU (Electronic Engine Control Unit) detects an error code in the system. For example, this happens when a sensor generates an error.
Since there are more than 200 possible error codes that can cause the engine light to come on, in order to determine the cause of the engine warning, you need to do an electronic diagnostic, which will show the error number. Using the code, you can determine what has gone wrong in the car. If you ignore this warning, there is a risk that it will lead to more serious engine damage.
7) Generator failure
The alternator is the part of your car that keeps all the electrical systems running when you start the car. It is also responsible for supplying charge to the battery to keep it in peak condition. If the alternator breaks down, it can cause premature battery wear and other problems when starting the car.
Check your machine manual or service book for recommended maintenance intervals for your generator and replace it before it breaks to avoid problems.
Also note that many generators can be iterated over. This way you can save a lot of money.
Weak spots
What weak points does the body of the domestic nine have? Let's try to find out.
If rotten or deformed elements of the car body are detected, they must be removed and appropriate measures taken to restore the integrity of these areas.
The most vulnerable areas of the VAZ 2109 body include:
- Front floor, reinforced sills, doors, fenders and rear underbody;
- The hood has relative endurance, but over time it begins to lose its former properties. The area above the battery is especially affected. This is where Nine owners most often notice the formation of rust;
- A noticeable problem that many drivers face is the fuel tank floor;
- Optics reflectors and a muffler also cannot boast of a long life without the appearance of signs of rust.
Corrosion is obvious
Corrosion is the main enemy of almost all domestic cars. Although anti-corrosion coatings are done quite well, time, weather conditions and the characteristics of our roads kill everything, rust actively begins to eat the metal and this problem must be dealt with.
What is an injector - a modern replacement for a carburetor
An injector is a device that replaces the operation of a carburetor and consists of a fuel rail (rail) onto which injectors are attached. Under high pressure from the gasoline pump, fuel enters the rack, and from there the gasoline is distributed to the injectors. The injector nozzles, using rubber sealing rings, are inserted together with the rack into the engine block and inject fuel, which then ignites.
An injector is a fairly thin device, the operation of which is constantly regulated by the electronic “brain” of the car. The presence of an on-board computer allows specialized car repair shops to carry out quick and accurate vehicle diagnostics. Diagnostics is carried out by connecting special equipment through a connector to the vehicle’s on-board computer.
Injection models of the VAZ 21099 since 2000 have also acquired electronic “brains”. This car model has front-wheel drive and shows high road stability. The engine of the injection 99 is four-cylinder, eight-valve, with a displacement of 1.5 liters. In a modern VAZ, the maximum speed indicated on the speedometer is 180 km/h. In practice, it is not recommended to accelerate this car over 160 km/h.
How to set up carburetor 21099
The outside of the device does not need to be washed if it is used regularly. Cleansing becomes necessary only when the internal mechanisms become very dirty and their mobility becomes difficult. Before you start adjusting the carburetor or taking your car in for repairs, you should also clean the mechanism. It is strictly forbidden to use brushes or dry rags for internal cleaning. Even the smallest and invisible lint can get inside the device and disrupt its operation. After the VAZ 21099 carburetor is brought into proper shape, you can begin to configure it.
Setting the throttle valve is the first step in carburetor adjustment. It consists of checking how well the damper cable is tensioned. It should neither sag nor be too tight.
If you need to tighten or loosen the cable, you should adjust the drive, which consists of several stages:
- A size 13 wrench holds the tip nut, and a second similar tool slightly unscrews the lock nut.
- The required distance from the tip of the nut to the carburetor is set. In this case, the gas pedal must be lowered.
- The locknut that was previously unscrewed with a wrench is tightened.
After the throttle valve is brought to the required state, you can proceed to setting up the air damper drive.
To do this you need:
- Remove the cover from the air filter.
- Check the draft level in the shell. This is done as follows: if the drive is adjusted correctly, then the air damper opens completely when the drive handle is screwed in. If the opening is not complete, it must be adjusted. The handle rotates 180 degrees so that the damper opens completely.
The next step is setting up the launcher. This mechanism can be adjusted correctly only with the carburetor removed. If this is problematic, then you should purchase a tachometer.
After the carburetor is removed, you need to do the following:
- Remove the air filter base.
- Pull out the air damper drive handle and open the damper itself by about a third.
- Start the engine, loosen the bolt to 3 - 3.5 thousand rpm and lower the throttle.
- Continue unscrewing the adjusting screw to 2.7 thousand rpm.
- When the required values are achieved, you can tighten the bolt back and return the filter base to its place.
It is also sometimes necessary to adjust the idle speed. To do this, warm up the engine and turn on power-consuming devices (headlights, stove, etc.). After this, using a screwdriver, set the maximum possible speed of the carburetor quality screw. On the contrary, the quantity screw decreases the normal speed. Next, you need to go to the quality screw again and lower the speed to the average value.
Fluid levels
Let's start, first of all, with the oil level in the engine - this is the most important parameter that characterizes its operation. With increasing mileage, engine oil consumption due to waste increases significantly, and the recommended replacement interval of 10,000 km may be too long. It is necessary to regularly check the level on the dipstick in the engine compartment, without waiting for the warning lamp on the instrument panel to light up, which will protect your engine from completely replacing the cylinder-piston group and grooving the crankshaft.
In addition, you should pay attention to a sharp increase in the oil level - most likely, there has been a leak of coolant into the lubrication systems or into the combustion chamber. Operation in such a situation should be stopped immediately
An additional confirmation of this disappointing conclusion can be a decrease in the level of coolant in the expansion tank.
In turn, the lack of this fluid leads to an increase in the operating temperature of the engine, frequent activation of the forced radiator fan, and can subsequently lead to boiling in the traffic jam. It is worth noting that in particularly advanced cases, systematic overheating causes warping of the cylinder head cover, which requires expensive repairs.
Brake fluid is also of particular importance, since the effectiveness of the most important safety system directly depends on it. This is a hygroscopic substance that needs not only control of its level, but also systematic replacement in order to avoid boiling and brake failure on a long descent.
It is also worth remembering about the transmission oil in the gearbox - it is not replaced as often as in the engine, so many car owners simply forget about this important procedure. For a manual transmission, this can lead to increased effort on the lever and the inability to engage one of the gears.
If these symptoms continue to be ignored, then excessive wear of the bearings occurs, which makes further operation impossible.
An automatic transmission is even more demanding on the level and condition of the working fluid, since changes in its properties during long-term operation lead to costly breakdowns and the risk of having to replace the entire assembly.
