Owners of domestic cars often face situations that are described sparingly in service manuals, and on forums they overgrown with legends. Lada KalinaDespite the mass production, it is able to present surprises that baffle even experienced mechanics. Strange sounds, unexplained electronics or sudden system failures are not always a sign of critical failure, but such signals cannot be ignored.
In this article, we will look at the most “very strange things” that happen to Kalina cars and offer practical solutions. We will touch on the issues of diagnostics of electrics, engine features and maintenance nuances that will help you save time and money. Understanding the nature of these anomalies will turn chaos into a system.
Before panicking when a new sound or smell appears, you need to conduct a primary visual and auditory diagnosis. Often the reason lies in the little things that are easy to overlook when a cursory examination. Car It is a complex mechanism where one fault can be disguised as another.
⚠️ Warning: If you smell a persistent burning smell or see sparkling wiring, immediately turn off the engine and turn off the battery. Continued movement can lead to fire.
Phantom currents and muffling electronics
One of the most common problems that generates “strange things” is the unstable operation of the onboard network. The owners complain that door-end He lives his life by making lights flash in the cabin or making errors on the dashboard. Often the problem lies not in the sensor itself, but in oxidized contacts or poor “mass.”
The electronic control unit (ECU) is also sensitive to voltage surges. If the generator is producing unstable current, controller It can change sensor readings randomly. This leads to floating idling speeds or a sudden transition of the engine to emergency mode. Checking the voltage at the battery terminals with the engine running is the first step to the solution.
To fix electrical problems, it is recommended to check the main grounding points. The body of the car oxidizes over time, and contact deteriorates. Cleaning contacts and using special lubricants often work wonders.
Hidden wiring problems
Often, wire harnesses are rubbed in the passageway through the body openings, especially in the area of corrugated doors. This causes a short circuit when opening the door.
Below is a list of the main symptoms that indicate electrical problems:
- ⚡ Unintentional actuation of wipers or headlamps.
- ⚡ Blinking indicators on the dashboard for no apparent reason.
- ⚡ The failure of the central lock to respond to the key fob.
- ⚡ Fast battery discharge per night (parasitic current).
Use a multimeter to check the voltage. The norm on the started engine is 13.5-14.5 Volts. If less, the problem is in the generator, if more, in the voltage regulator.
Mysterious sounds of suspension and steering
The suspension of the Lada Kalina is structurally simple, but its elements tend to wear out unevenly, creating acoustic illusions. A knock that is heard only on a warmed-up car or, conversely, only in the cold can be confusing. Often the culprit is the one who is guilty. steering-rail, which begins to knock due to the production in the gears or weakening of the pressing mechanism.
Silent blocks and ball supports when worn can make sounds similar to the crunch of bearings. It is important to locate the source of the noise. For this purpose, a technical hearing or a mechanical stethoscope is used. Sometimes the sound is transmitted through the body from a completely different node, creating a false impression of the place of failure.
Particular attention should be paid to the stabilizer racks. Their rapid wear is a frequent cause of knocking on small irregularities. Replacing these components usually does not require complex equipment and can be done in garage conditions.
| Type of sound | Probable cause | Method of verification |
|---|---|---|
| Deaf knocking in front | Wearing of Silentblocks | Rolling the car on the spot |
| Screaming at the turn | Steering joints | Rotating the steering wheel in place |
| Hum at speed | Stack bearing | Diagnosis by hearing when moving |
| Knocking on the bumps | Stabilizer struts | Visual examination of the backlash |
Engine: triple and floating revolutions
The power units of the VAZ installed on the Kalina are known for their survivability, but they are also susceptible to “childhood diseases”. The sudden trifle of the engine is often associated with the ignition system. Candles, coils and high-voltage wires require regular revision. Ignition module - a node that often fails precisely due to overheating or breakdown.
Floating turns of idling can be caused by the sucking of unaccounted air. Cracks in the nozzles, sealing rings of nozzles or throttle disrupt the mixture. ECU tries to compensate for this, pulling the engine in plus, then in minus in terms of revs.
Adjusting the heat gap of the valves is a procedure that many ignore, and in vain. On engines without hydraulic compensators, the gaps “float away”, which leads to noise and loss of power. Adjustment should be carried out every 30 thousand kilometers of run.
⚠️ Note: When replacing the belt, strictly observe the labels. An error on one tooth can lead to a meeting of valves with pistons and overhaul of the engine.
For the diagnosis of the ignition system, it is useful to have spare candles and a coil. By eliminating the defective element, you can quickly find the defective element. It is also worth checking the compression in all cylinders - a difference of more than 1 atmosphere indicates problems with the CPG or valves.
☑️ Engine diagnostics
Transmission: howling boxes and tight run
The manual transmission on the Kalina is often criticized for noise and fuzzy switching. However, many problems are solved by changing the oil and adjusting the scenes. Transmission oil Over time, it loses its properties, and the box begins to buzz, especially on the cold.
Tight stroke of the gearbox lever can be caused by souring of the switching cables or wear of plastic bushings in the gear selection mechanism. Lubrication of the nodes and replacement of worn-out elements return the ease of switching. Sometimes the problem lies in the wrong clutch or squeezed bearing.
Vibration on the body when the gear is on often indicates problems with the engine support or gearbox. Resinometallic supports extinguish vibrations, and their destruction transmits all vibrations to the body, creating discomfort to the driver and passengers.
If you hear a crunch when changing gears, this may indicate wear of synchronizers. In this case, a double clutch or a full stop is required to turn on the gear, which is a sign of the need to repair the gearbox.
Body features and corrosion
The body of the Lada Kalina has its own vulnerabilities where corrosion appears first. Wheel arches, thresholds and bottoms of doors are high-risk areas. Regular washing and anticory treatment significantly prolong the life of the body. Ignoring small chips leads to the growth of "redheads".
Strange creaks in the cabin are often caused by friction of plastic skin elements. Plugging joints with antiscript or using special lubricants for plastic helps eliminate annoying sounds. This is especially true in the winter when plastic is becoming tougher.
Drainage holes in doors and spars should be cleaned periodically. Clogged with dirt water stagnates inside the structures, causing the metal to rot from the inside out. This is a hidden threat that is not visible on external inspection.
Regular anti-corrosion treatment of hidden body cavities extends the life of the car by 5-7 years and maintains its market value.
Cooling system: boiling and air traffic jams
The engine cooling system on the Kalina is prone to the formation of air traffic jams, which leads to overheating and "boiling" of antifreeze. The thermostat is a key element that often jams in the closed position. Checking its operation is simple: the lower radiator tube should be heated simultaneously with the upper one after warming up.
The cover of the expansion tank plays the role of a valve that maintains the pressure in the system. If the valve does not hold the pressure or, conversely, jams, this will either lead to boiling or to the collapse of the pipes. Replacing the cover with a quality one is a cheap way to avoid problems.
The cooling fan shall be clearly activated when a certain temperature is reached. If it turns on too late or doesn’t work at all, the engine can get heat stroke. Checking the electric circuit of the fan and the motor itself should be part of routine maintenance.
How to properly remove the air traffic jam?
To remove the air traffic jam, it is necessary to raise the front of the car, open the lid of the expansion tank and start the engine. Let him warm up before the fan is turned on, periodically gasping. Add antifreeze as the air goes away. After the procedure, check the fluid level.
Which antifreeze is better to pour?
It is recommended to use G12+ or G12++ antifreezes that meet the Renault-Nissan specifications (e.g. CoolStream Premium). Mixing different types of antifreeze can lead to the formation of sediment and corrosion of the system.
Why is the pump flowing?
The pump leak is often caused by wear of the obal or gasket. On Kalina, the pump is given by the timing belt, so its replacement is better combined with a belt replacement to avoid re-disassembly of the unit in the future.
What to do if the engine is boiling?
Stop immediately, but do not shut down the engine immediately (unless there is an antifreeze leak). Open the hood for better cooling. Do not open the radiator cover on a hot engine - it is dangerous with burns. Wait for cooling and check the fluid level.
Do I need to wash the cooling system?
Yes, when replacing antifreeze, it is recommended to wash the system with distilled water or a special wash to remove scaling and residues of old liquid. This will ensure efficient heat exchange and prolong the life of the new liquid.
