How to improve

It is proposed to put thermal insulation on the tubes going from the compressor to the air conditioner evaporator, for example, K-FLEX (after cutting it lengthwise). As a result, it is possible to increase the performance of the air conditioner by reducing cold losses. After modification, not just cold, but icy air should come out of the air ducts.

Reference

: K-FLEX is used in refrigeration equipment, air conditioning and ventilation systems, and energy. This universal thermal insulation is designed to protect industrial pipelines, heating systems, petrochemical facilities, and refrigeration units from heat losses.

Largus dashboard

The Largus instrument panel, which you can buy in our showroom with delivery in Moscow and the region, looks great, the plastic is pleasant to the touch, and the dials of electrical appliances look respectable. However, the steering wheel installed on the vehicle is very reliable and beautiful. The audio system is also excellent, it not only gives good sound, but also makes it possible to connect a mobile phone and talk on it without holding it in your hands. Largus has a climate system and on-board computer equipment, which displays all the data important to the car owner:

1. Amount of gasoline.
2. Motor rally.
3. Speed ​​mode.
4. Gasoline consumption is average.

By the way, the average consumption per 100 km is approximately 11 liters of fuel. On the road, the Largus car behaves confidently and overcomes bumps excellently. Moves calmly at 100 km/h. Thanks to the instrumentation, the driver can monitor the condition of the car.

Air conditioning in hot weather and in traffic jams

It is believed that almost all budget cars are equipped with air conditioners, which practically do not cool the air, especially in hot conditions and traffic jams. It turns out that manufacturers really save on the air conditioning system. Lada Largus also has similar devices in many trim levels. The system was tested and we will now describe its results in detail.

Air conditioning operation in the cabin

To check the operation of the air conditioner, it was decided to go out onto the city streets in the extreme heat. It was noon and the thermometer showed +32 degrees Celsius. The trip lasted about 1.5 hours. And all this time it was quite comfortable in the car. Of course, on the last, third row of seats there were no such flows of cool air as in front, but still it was not hot. It is worth noting that if the rear half is tinted according to GOST, it will probably be even better.

On video - testing the air conditioner in Lada Largus

The air flow regulating “rounds” are quite convenient to use. They rotate easily and direct jets of cool air to the desired location. Checking the temperature control of the air conditioner was also pleasing. When switching the temperature from maximum cool to medium, the cabin actually became a little warmer.

You can also adjust the fan speed. It is most comfortable when it is exposed to o. You can, of course, set it to high speed, but then it’s too windy.

If you want to cool the car interior as much as possible, then you should set the air intake switch to the internal circulation position. In this case, the air intake from outside will be blocked and it will actually be cooler.

In general, the air conditioning in Largus works fine. The only noticeable disadvantage is a slight decrease in engine power and an increase in fuel consumption. Under hot conditions and stuck in serious traffic jams, the gasoline consumption was 13.2 liters.

Instrument clusters for popular models VAZ 2110, VAZ 2114, Lada Kalina, Lada Priora

Today, tuning the instrument cluster can be done on all VAZ models. All devices differ from each other in the presence of certain functions, the use of the latest technologies, modern design and ease of operation. At the same time, much attention was paid to driver safety when developing the instrument cluster. Suffice it to say that thanks to such a device you will always be aware of all current parameters, airbags, power steering, ABS, and you can also diagnose all these parameters, which means you can prevent a malfunction in a timely manner.

Some devices are equipped with “auto light” functions, which allow you to automatically switch the lights to day or night mode, as well as traffic alerts with the handbrake active or low beam headlights turned off. These are just some of the functions that modern VAZ instrument clusters have.

Exterior of Lada Largus

As already mentioned, the appearance of the Lada Largus is an almost complete copy of Logan with some small touches from AvtoVAZ. The car’s belonging to Tolyatti manufacturers is most clearly visible from the front, by the characteristic emblem on the radiator grille. The headlights look rather modest; the picture is completed by a bumper with smooth outlines and a large air intake mouth.

When viewed from other sides, Lada Largus looks like an ordinary station wagon from any manufacturer. All similar models are characterized by a sloping hood, a flat roof, and side glazing that takes up a large area. At the rear, judging by the photo, you can see two asymmetrical doors, a non-bulky bumper and vertically oriented optics on the sides.

The center console of the instrument panel is orange on the Lada Largus Cross

Electrical equipment in a Largus car

The electrical circuit in a car provides for the presence of two global categories of devices: consumers of supply voltage and devices that generate current. These nodes are connected via cable lines comprising a single on-board network. The network in LADA Largus operates according to this principle. By the way, in this car there are no negative wires (to the edge of the battery), and the role of the negative contact is performed by the body itself.

Interior of Lada Largus

The interior of the car, as can be seen from the photo, is practically indistinguishable from the same Logan and is just as ascetic and unremarkable. In the arrangement of instruments and other elements, you can notice the same ergonomic errors that were characteristic of Logan. The set of instruments is laconic, the two-color screen of the course computer and instrument dials are surrounded by chrome trim. The information content of the devices is quite good. The steering wheel is large, mounted on three spokes and has the AvtoVAZ logo in the center.

The number of controls on the central panel is minimal. In the maximum configuration you can find a radio with AUX and USB connectors; in the initial and middle configurations there is a plastic plug instead of a radio. Nearby are the controls for ventilation and heating (air conditioning and stove). Between them there are also buttons for the electric windows of the front windows, the rear door lock, the heated rear window and the hazard warning lights.

All upholstery is made of hard plastic and fabric, and the comfort provided by the seats is minimal. The front seats are quite flat, lateral support is minimal, but the range of adjustment is quite wide. In the luxury version, the driver's seat even has lumbar support and seat height adjustment.

There is also more than enough space for passengers in the second and third rows; the roof does not create an oppressive impression, however, climbing into the third row is not very convenient. However, the car was created to transport goods and passengers on a budget basis. It doesn’t have to be very comfortable, but it copes with its main tasks perfectly well. Despite the cheapness of the interior and upholstery, everything is made quite well and firmly; unnecessary noise or squeaks from poorly secured elements are not annoying, as in other similar cars of this class.

When is pinout required (device chips) and how to do it

All car parts fail sooner or later. There are times when they need to not only be repaired, but replaced. The instrument panel may also break, causing it to be removed and a new one installed in its place. This work is easy to do with your own hands if you have at least the slightest knowledge of mechanics. If you are well versed in your Priora (sedan), then you need to perform the pinout in this way:

1. First, the dial hands are removed using a regular knife.
2. Next, the gasket in the speedometer is scraped out to replace the backlight.
3. If there is no need to change the sensors, you can simply remove them and clean them.

Very often, motorists cover the panel with a special LED strip to achieve even lighting. You can also use CMD diodes, which can be easily fused into glass with a soldering iron. To do this, you need to disassemble the dial and solder diodes directly under the base of the hands.

If you understand the purpose of all the contacts, and also know the purpose of a particular connector on the panel, then you can easily do the pinout yourself. The main thing is to carry out everything strictly according to the instructions so that the connection is successful and the panel continues to function efficiently. If you know which is better to install a tidy: with a canbus or a regular one, then it’s better to ask professionals who understand this. If you have no experience in such work, and you do not understand the purpose of certain wires, then the technical service will help you improve the operation of the instrument panel. Of course, you will have to pay for this, but you will not waste your time, and the work will be done efficiently.

Fan replacement

If the stove fan stops working, or it makes strange sounds, then it is necessary to dismantle it, clean it or replace it. However, you should not rush to replace it; first you need to make sure that the brushes of the mechanism are intact, in which case replacement will not be required. Getting to this part is not so easy, but for cars with the Lada “tenth” family design, there is a time-tested reliable way to get to the fan:

• Release the right side of the instrument panel by unscrewing the eight screws, then the panel must be lifted.
• Afterwards it is necessary to remove the standard sound insulation of the engine shield.
• Next, you will need to take a position in the cabin so that your shoulders rest on the mat; this is the easiest way to reach the fan.

Removing the fan is quite simple. All you need is the necessary tools and a little time. By unscrewing the three screws of the casing cover and removing the frame of the radiator pipe seal, you can remove the device. But before changing a part, you need to determine whether it works or not.

After all, it often happens that a dismantled fan spins and functions normally, but as soon as it is put back in place, it immediately ceases to fulfill its direct duties. The reason for this is most often accumulated small particles that prevent normal contact in the mechanism.

Largus car dashboard

The showroom of such a popular car as the Lada Largus is almost completely similar to the Renault Logan showroom. Almost the same central car panel, round air ducts and buttons. The Largus instrument panel has only slightly changed, the buttons on the console in the center have been updated, and the insert is varnished. The scales themselves now have a silver edging. The Largus instrument panel itself, which can be ordered with delivery in Moscow and the region, is assembled, consists of a frame and a decorative car panel. Steel frame. It is to this that the system units and electrical wiring harnesses of the car equipment are attached, as well as all the steering elements. The frame itself is attached to the front shield, front pillars and the body base.

It is an integral element of the power structure of the car body. As for the decor, the element is made of plastic, which is attached to the frame with screws. The controls for the car as a whole and the climate system are attached to it. There are also control devices and linings that cover the units. The catalog on the website presents a large assortment of auto parts, parts, components, consumables and additional equipment for VAZ and Renault cars. Choosing what you need is not difficult. However, if you have problems with the choice, contact the company manager by contacting him in any available way.

The manager will help you navigate the assortment, tell you about the terms of cooperation, payment, delivery, and, if possible, offer a discount. We will be glad to new cooperation, our prices are low, guarantees from the manufacturer are provided.

Ignition system in Largus

Now the “switching baton” is passed to the ignition coil. This element directs high voltage power to the spark plugs and does this according to a specific algorithm. Plugs are necessary to create a spark inside the combustion chambers, which leads to ignition of the mixture. To make the combustion process possible and occur with sufficient efficiency, the coil generates a voltage reaching 30,000 V. The coil is powered from a standard 12-volt network.

Methods for connecting to the main electrical wiring of Lada Largus

Regarding the issue of electrical commutation, the more relevant discussion will be not how to connect the wires, but with what. Almost everyone has enough skills to connect a couple of conductors. Now you need to be able to connect them efficiently or reliably. We will also discuss with you the best way to insert into the existing electrical wiring and how to do it.

Connecting wires to standard wiring

The easiest way, of course, is to make the connection using regular twisting. But this kind of method “is not comme il faut.” Contact will be lost sooner or later. In general, it cannot be called reliable. But this is really the simplest and enough to first test the switching made.

If you have soldering skills, tinning and soldering conductors will be a simple and reliable way. This kind of connection will never oxidize over time, and its strength will be comparable to the strength of the conductor itself. That's why soldering is good.

But it’s not soldering alone that can help you out in the matter of connecting rear lights to the Lada Largus. A cheap and practical way would be to use the most common screw terminal blocks. They cost pennies and are sold in almost any electrical goods store. To avoid cutting the main wiring, bend it at the connection point and thus clamp it with a screw contact.

Well, the most optimal would be to use special terminal blocks, known as clamp couplers. They are specifically designed to connect to live electrical wiring without twisting, soldering or cutting. Perhaps this method can be considered a priority. We will finally move on to the connection process itself.

Electrical connection diagram, how to connect the wires correctly

Let's take in our hands a working electrical plug that is connected to the main lights of the Lada Largus. It comes with wires of five different colors, including:

• common wire, also known as “plus”;
• power supply for direction indicators;
• for fog lights;
• in reverse;
• on the brake, as well as the clearance.

Among all this not very tricky interweaving of multi-colored conductors, we are interested in the following colors:

• black - common wire;
• orange - responsible for the brake light;
• blue - responsible for dimensions.

This is exactly the connection scheme that is allowed on the Lada Largus. Rear lights installed instead of trims, of course, can be connected to any other wires in the plug, but this will contradict the technical regulations of AvtoVAZ, therefore we will not invent anything of our own and will not teach you anything bad. Additional lighting conductors have the following insulation colors:

• black - common “positive” conductor;
• red - to be connected to the orange on the plug, it is responsible for the brake light;
• yellow - to be connected to the blue one on the plug, it is responsible for the dimensions.

The electrical connection has no other nuances. Before final assembly of the casing, it is recommended, however, to test the correct functioning of the additional lights. This will help you avoid a “bad job” if you make a mistake. In general, there should be no problems, everything is extremely simple, and soon you will be able to independently drive along the roads in an updated and tuned Lada Largus, to the envy of everyone.

Some technical characteristics and general description

In order not to buy a pig in a poke, having decided to stylishly tune your car, it is advisable to familiarize yourself with the proposed description of the technical characteristics of the product. What material is the additional lighting made of, how long will it last, and how justified is such a purchase? Let's figure it out together. A meager description on the packaging is one thing, and an objective view from the outside is another.

Let’s say right away that such lights shine really well on Largus. It is also noteworthy that this illumination is practically indistinguishable from the illumination of the main lights and is, in fact, its logical continuation. This will definitely emphasize the individuality of your car and will be a simple, but at the same time effective visual tuning.

When it comes to light source technology, LED lighting is currently the most technologically advanced. It is capable of providing high-quality light for tens of thousands of hours and for at least ten years. Such lamps are also not afraid of low temperatures, are economical and shock-resistant. They do not heat up the lamp body like outdated halogen samples. In general, it’s a pleasure.

Attaching new skin

Installation of all working parts and components is carried out in the reverse order of removal. Rubbing parts are lubricated, sliding surfaces in the door lock, stops, hinges, and rod hinges too. Before installing the upholstery, be sure to connect the ground wire terminal to the battery, check the operation of the door lock, and if necessary, adjust it. To check the operation of the window regulator, raise the lowered window. You can also restore or replace the seal-sealant at the end of the upholstery, if necessary.
