Location of cables and heater dampers on a VAZ 2105 injector

For any car operating in the cold season, the importance of flawless heater operation cannot be overestimated. You can have different attitudes to the heat, but you’re unlikely to find anyone who likes to ride in a car wearing felt boots and fur mittens. Therefore, any heater malfunction that occurs in winter will be considered a disaster, regardless of the make and model of the car. If we talk about the VAZ-2105 stove, then it can hardly be called a technically perfect device - heater breakdowns are not that rare, and many owners have questions about the heating efficiency. Therefore, the improvement and repair of the VAZ 2105 stove are procedures that are of interest to the majority of “A” owners who are forced to use a sedan even in severe frosts.


How to independently repair and replace a VAZ 2105 stove.

Processing the engine compartment

But one more problem remains - the long time it takes to warm up the interior. And to eliminate it, you need to insulate the engine. This will allow the engine to reach operating temperature faster and cool down more slowly.

But it is not possible to insulate the motor itself; there are a significant number of moving elements on it that cannot be covered. But insulation of the engine compartment is allowed.

First you need to insulate the hood of the VAZ-2107. To do this, you can purchase a special cover from the auto store that is attached to the cover from the inside of the hood.

But many car enthusiasts prefer to do this with improvised materials. But when deciding to treat the hood, you should choose the right insulating materials. They must be non-flammable and not absorb oil. Therefore, it is not recommended to use ordinary fabrics.

The engine compartment can be better insulated by gluing insulating materials onto the shield separating the engine from the passenger compartment. But this can only be done by removing the engine from the car.

We recommend: Replacing the pump on a 16-valve Priora

In addition to the hood, the radiator also needs to be insulated. For this purpose, masks are used that are attached to the radiator grille.

Instead of a mask, you can use a regular cardboard sheet placed between the radiator and the grille. But it is worth considering that you cannot completely close the radiator; heat exchange must still occur. Therefore, a sheet of cardboard should not cover more than 2/3 of the radiator area.

There is no need to take this into account with a mask, since in addition to the grille, there are enough holes in the front end for the air flow to pass to the radiator.

DAAZ

Second place, after Ozon, was occupied by DAAZ. This VAZ 2107 carburetor, unlike its “colleagues,” had an economizer device that provided forced idling. This difference did not have a significant impact and did not make this mechanism special.

Since “DAAZ” is a modification of “Ozone”, it also has options with the index 1107010 and 1107010 - 20. It is impossible to immediately say which carburetor is better to install on the Lada 2107. To do this, you need to decide what exactly you want to get from this device.

Disassembling, cleaning and assembling the VAZ 2107 “DAAZ” carburetor is one of the simplest tasks compared to cleaning other models. Although the layout of the unit is no different from the others, its design was somewhat simpler.

Radiator and heater fan

You should know that in order to always keep the interior of a five-wheeler warm and cozy, especially on winter days, you need to be able to increase the amount of heat supplied. Which part is directly responsible for supplying warm air? Of course, the radiator. But there is a problem - at the top five the fan is so loud that it makes you laugh. It is very small and simply not capable of creating the required flow. What to do? First, let's compare the fans on the VAZ 2105 and the VAZ 2108. The first motor consumes 4.5 A current and has a rotation speed of 3000 rpm, and the second one 14 A, but spins 4100 rpm. This already says something. It is recommended to replace the fan with another one.

Replacing the heater fan VAZ 2105

Replacing the heater fan on a VAZ 2105 is carried out as follows:

  • the lower part of the stove is removed (this is a simple casing, on top of which a regular electric fan is installed);
  • the old fan is removed;
  • we cut off one of the aerodynamic ridges that supply air to the legs of the driver and passenger (this is done due to the fact that the fan motor of the VAZ 2108 is much longer);
  • the impeller is also removed, which will not allow the fan from the VAZ 2108 to sit in place;
  • Instead, a homemade one is installed.

Advice. In order not to remove the impeller, but to leave everything as is, you can use another fan. A standard five-bladed fan for classics, which has a motor several times more powerful, is suitable. And its weight is much lighter, and the rotor of the new motor rotates stronger than even that of the VAZ 2108.

  • increase the diameter of the impeller hole;
  • we insert a new shaft there (we do this very carefully so as not to break the impeller);

  • connect the fan and check its operation;
  • adjust the resistor and assemble everything in reverse order.

Heater VAZ 2105 fan replacement

Advice. It is recommended to replace the resistor on the five by installing the eight version. The new resistor must ensure quiet operation of the fan. The fan switch should also be replaced.

Replacing the stove on a VAZ-2101, 2102, 2105, 2106, 2107

Most often, a malfunction of the heater radiator is detected when a puddle of antifreeze or water forms under the feet of the driver or front passenger, or when you turn on the heater in winter, instead of warm air, you get a stream of cold air, and again a puddle of antifreeze in the cabin.

The reason for this is a leak in the car's heating system. The result of such a malfunction is a spoiled mood and cool temperature in the cabin. This problem can be easily corrected on your own. For some VAZ models it will take very little time - VAZ-2101, VAZ-2102. Replacing the stove in a VAZ-2105, 2106, 2107 will require more fuss; repairing the heating system on these cars is not much different, but things are a little more complicated with the radio panel. In this article you will find useful information and guidance on replacing the heater radiator of VAZ cars.

First of all, you need to find out the reasons for the malfunction of the car heating system:

1. Antifreeze leak. There may be several reasons for an antifreeze leak in the car interior; they can be identified by visual inspection: a rusted heater radiator, a metal pipe, or a heater faucet. If your problem lies in the stove pipe or tap, then they can be replaced without disassembling the central panel and radiator casing. In this case, repairs will not require much effort and time. If it happens that the cause of the leak is a rusted radiator, then there are two options to deal with this problem. If you have a copper radiator installed, then you can solder it and tin it. You can do this yourself if you have the necessary skills, or find a master. If you have an aluminum stove radiator installed, then it would be most advisable to replace it with a new one, since such radiators usually cannot be repaired.

2. Cold air flow from the blowers when the heater is on. This phenomenon indicates impaired circulation of coolant in the vehicle’s heating system. This could be due to a malfunctioning heater tap or a clogged radiator. The faucet can be replaced, but it’s up to you to decide what to do with the radiator - either buy a new one or contact a radiator specialist.

The reasons are clear. Now you can start repairing the VAZ-2101, 2102, 2105, 2106 stove,

2107. For repairs you will need the following tools:

The tools required for this are Phillips and regular screwdrivers, open-end and socket wrenches for 7, 8 and 10. You will also need three rubber gaskets, silicone sealant and a liter of coolant.

The process of replacing the heater radiator on VAZ cars is described in detail below:

1. The coolant should be drained, this will make replacing the stove much easier. Although you don’t have to drain it, the losses will be small. Moreover, you have 1 liter of coolant in stock.

2

Unscrew the clamps on the radiator pipes and carefully remove the hoses; coolant may leak out of them.

3. Unscrew the 2 screws securing the rubber seal and remove it from the pipes.

4. In the cabin, remove the radio panel; it is usually secured with two self-tapping screws.

5. Using a size 7 wrench or a screwdriver, unscrew the fastening of the radiator tap drive cable, and then disconnect the cable from the tap.

6. Look for four spring clips on the fan housing and remove them. This can be conveniently done using a screwdriver.

7. Lower the fan housing down and move it to the side. It will not be possible to completely remove the casing - the power supply wiring to the electric motor will interfere.

8. Carefully pull the heater radiator out of the casing.

After these steps have been completed, you must carefully examine the heater radiator, metal tubes and faucet for signs of rust and leakage. If the tube shows signs of severe corrosion, then it should be replaced. The stove tap may also be faulty: if the tap handle is jammed (i.e. the tap does not open or close) or traces of coolant leakage are visible, then it must be replaced.

In the event that you had to replace the stove radiator itself, then both the tube and the tap from the old radiator can be screwed onto a new one. It is also necessary to install new gaskets: lubricate the gaskets with silicone sealant, and then tightly, but not too tightly, so as not to crush the gasket and tear off the threads, screw the metal tube and tap to the radiator. It is worth lubricating the radiator tubes with silicone sealant before attaching rubber hoses to them.

When the replacement of parts is completed, install the elements of the heating system in the reverse order, then fill in the coolant, start the car and check the tightness of the connections of the pipes and hoses. The replacement of the VAZ heater radiator has been completed. Now the inside of your car will be warm and comfortable.

Operating procedure

Before you begin removing the radiator, you need to prepare the necessary tools. Namely:

  • Two keys - 7 and 10;
  • Screwdrivers (phillips and flathead);
  • Rags;
  • Two new rubber gaskets;
  • Four liters of coolant.

Before starting work, place a rag on the floor mats. It will protect them from getting antifreeze or antifreeze while the stove radiator is being replaced.

First of all, clear access to the heater casing. This must be done by removing the bottom and shelf of the glove compartment, and also by disassembling the radio panel. Once the casing is released, it must be removed. Now, the stove radiator itself has opened in front of you.

All the work that needs to be done from inside the car is completed, let's move on to the engine compartment. On VAZ 2105 and 2107, there are two pipes from the cooling system to the heater radiator. On each of them there are clamps. They need to be released and the pipes disconnected from the stove. Also, carefully inspect the clamps for corrosion. If these hot spots are found, the clamps will need replacement. Otherwise, the source of corrosion may transfer to the thread, and you will not be able to loosen this part.

Once the clamps are removed, you will need to remove the diaphragm. It is attached with two 7mm bolts to the heater radiator. The last thing that holds the stove in place is the heater control cable. Let's remove the loop from it, and that's it, the radiator can be removed.

You need to remove it carefully without damaging the tubes. Otherwise, after reinstallation, they will leak and will need to be replaced. To disconnect them from the radiator, take a 10mm wrench and unscrew all the fasteners (there should be four of them).

Now, through the hole on which the pipes were attached, you can inspect the part from the inside and determine whether it needs replacement, or whether cleaning can be done.

Replacing the heater fan

The previous post “heater noise VAZ 2101 - 2107” revealed to us the main sources of noise in the heating system. And it may happen that the fan motor will need to be replaced. I will try to tell you how to do this in more detail.

Connection diagram and details of the electric motor of the heater VAZ 2101 - 2107

1 – battery; 2 – generator; 3 – ignition switch; 4 – fuse block;

5 – heater switch; 6 – additional resistor; 7 – heater fan electric motor.

It is useful to know about the parts of the heater; if you have disassembled the heater motor, then during reassembly this picture will serve as a small manual for you.

1 – lock washer; 2 – washers; 3 – body;

4 – anchor; 5 – crackers; 6 – cover

Installing a stove radiator

Installing the radiator is done in the reverse order. To prevent future coolant leaks, it is better to replace the radiator clamps and pipes with new ones. This especially applies to pipes.

Open the heater valve before adding coolant. After adding antifreeze, you need to start the engine and let it run a little at high speeds. The circulation of coolant from the pump will expel any air pockets that could have formed when filling it. After all this, we check the antifreeze level and if it is low, then add it to the radiator and expansion tank to the mark.

  1. Drain the coolant.
  2. Loosen the clamps and disconnect the pipe that comes from the radiator and the inlet.
  3. Loosen the clamps themselves.
  4. Remove the pipes by disconnecting them from the water pump.
  5. We take out the thermostat. Disconnect the remaining pipes.

When installing the thermostat, you need to take note that this is a serious operation and must be carried out carefully:

  1. Clean all surfaces thoroughly and replace the O-ring.
  2. Correctly orient and place the thermostat in the housing.
  3. Next, tighten all existing cover bolts. To be able to do this, you need to try.
  4. Reinstall all hoses in their original locations, then fill with coolant.
  5. You should also start the engine until it reaches operating temperature to make sure there are no leaks.

Assembly

Assembling the VAZ 2107 heater occurs in the reverse order. First, we screw the pipes to the radiator and thread the part into the hole between the body and the engine. We put on the loop of the stove control cable and install the diaphragm. We connect the pipes, and be sure to tighten their edges with clamps.

When repairing or replacing this mechanism, it is recommended to replace all gaskets in order to increase their service life. The final step is to reinstall the radio panel and assemble the glove compartment. Replacement of the VAZ 2107 radiator is completed. Now, start the engine, warm it up for 5-10 minutes, and turn on the heater. First, do not forget to open the faucet, which is located under the dashboard, on the passenger side. If warm air is blowing from the vents, then the problem is solved, but if not, then it is better to contact a specialist.

How to remove and replace the heater motor on VAZ-2107, 2105 and 2104

So, dear friends, today we will tell you in an accessible language how to get to the heater motor on a VAZ-2107 in order to replace it or repair it, depending on what forced you to take it out. Let us immediately note that if the heater motor on your seven began to squeal when cold, or squeal, then this will only get worse, the motors from the factory are bushed, lubrication will not lead to anything, it may return you silence for a short time, but not for long, so in this case only replacement. And ideally, replacing the heater with a bearing motor - it certainly won’t squeal. So, first we will need to remove the beard on our seven. First, we remove the gear shift knob, it will interfere with us, and we remove the radio from the shaft and disconnect the connectors. It’s different for everyone, some may not even have a radio.

First, let’s unscrew the shelf, everything is simple here, the action is in three photos:

To further remove the beard, we need to remove the panel with the clock and cigarette lighter, pry it off from the right or left side with a flat screwdriver and pull it out of the latches:

Then, we disconnect the wires from the clock, the cigarette lighter (for ease of assembly, I would advise marking them), remove the socket to the side and gain access to two nuts, here it will be convenient to use a 10 mm socket wrench

We unscrew the nuts, do not lose the washers, look down where the buttons are. There is a decorative plug on the side that looks at the rear passengers; we pry it off with a screwdriver, and under it we see two screws screwed into the tunnel:

We unscrew them, disconnect the pads from the buttons, the panel no longer holds anything. We move it to the side and gain access to the stove body:

Now, we disconnect the side air ducts and carefully remove them from the latches with a flat screwdriver (the photo shows how they snap into place):

We are interested in the lower and middle parts of the body of the stove 2107, in order to remove them you need to get close to the metal latches, there are only four of them - two on each side, here they are:

It can be problematic to snap them off with your hands, we recommend using a screwdriver, like in this picture:

After the latches are removed (be careful when removing, they may “shoot” and fly away in an unknown direction), the lower part of the stove body can be easily pulled out by hand:

Here we see our motor. The motor itself is held in the lower part of the case, also on two metal latches; we snap them off and disconnect the terminals

and remove our motor from the stove body:

That's all, assembly is carried out in the reverse order, about 40 minutes are spent on everything. By analogy, the heater motor is replaced on the VAZ-2105 and VAZ-2104, the only difference is in the beard itself and its fastenings. A little later we will tell you about the nuances of replacing the heater motor in these and other VAZ models. Good luck on the roads and don’t let your car break down. We will be glad to see you in our VAZ classics club on the forum.

Installation

The new electric drive is installed in the reverse order. Do not forget to check the functionality of the purchased unit before installation. This will avoid unnecessary steps to re-disassemble the heater. Check if the engine is functioning

Fortunately, just connect it to the battery installed on the car directly.

When replacing the fan, it makes sense to also inspect other elements of the heating system of your “Seven”. Make sure that:

  • there is no damage to them;
  • the seal is not broken.

Pay special attention to the heater valve and radiator. Timely detection of problems will allow them to be eliminated with minimal expenditure of money and time.

Electric motor parts and heater switching diagram for VAZ 2107

1 - battery; 2 - generator; 3 — ignition switch; 4 - fuse block; 5 — heater switch; 6 — additional resistor; 7 — heater fan electric motor

The easiest way to replace an electric motor is in VAZ 2101, 2103, 2106 cars. In a VAZ 2107 car this is always associated with minor difficulties, since it has a more extensive ventilation system, placement of buttons, etc. That is why I would like to consider how to replace the stove fan exactly on this this make of car.

So, how to replace the VAZ 2107 stove fan:

1. First of all, you should move the lever (lower) to the extreme right position, this is done so that the side air duct dampers close. 2. Remove the instrument panel. 3. Then we move to the opposite side and remove the glove compartment body and the shelf for things. 4. We outline the wires and remove the beard, carefully, without tugging, remember what is located and where. 5. Using a 7 key, loosen the cable fastening and disconnect the rod.

6. Remove the end of the damper drive cable

7. Using a 10mm wrench, unscrew the nut that secures the heater radiator casing. It is located behind the central air duct.

8. Remove the ground wire from the stud

9. Then you should unscrew the fasteners of the right air duct. 10. We do the same with the left air duct.

11. We remove the side air ducts from the heater body using a screwdriver.

12. Remove the entire assembled casing.

13. Remove the fan from the housing, passing the wires inside, and disconnect the terminal from the resistor

14

Remove the impeller, paying attention to the adjusting washers

15. Disconnect the spring clips and remove the heater heater motor.

Assembly is carried out in reverse order.

Notes on replacing the fan: -You should only disassemble the electric motor yourself to check and clean the commutator. -If the stove is disassembled, you can at the same time inspect the remaining parts of the interior heater. -In order for the radiator to produce more heat, it should be washed. This can be done by using water pressure from a hose connected to the radiator inlet or outlet pipe.

Basic faults

As a rule, a heater failure occurs due to the fact that its electric motor stops functioning. There are several reasons for this:

  • combustion of the fuse link;
  • breakage of the electrical circuit wires responsible for its operation;
  • switch failure.

In the first case, the faulty protective device must be replaced. If the new fuse burns out, you need to find out why this is happening. Most often this happens if there is damage to the insulation of the wires or their separation from the connecting terminals. The electrical circuit is tested with a multimeter, and if a defect is detected, it is eliminated.

The regulator, in turn, usually does not work properly when its contacts burn out. A broken pusher also causes a similar result. The serviceability of this element is determined by measuring the voltage at its side contacts. Its presence when switching the toggle switch indicates operability. Otherwise, this unit will need to be replaced.

In addition, the motor itself may fail. The most common reasons are:

  • breakage of armature winding wires;
  • brushes sticking;
  • collector oxidation.

If eliminating these causes does not correct the problem, then the engine is completely changed.

Sometimes a malfunction occurs due to a break in the wires supplying the mounting block or due to a burnout of the current-carrying track in it.

And finally, destruction of the resistor circuit may also occur - it is checked and the element that has become unusable is replaced with a serviceable one.

Replacing the stove on a VAZ-2101, 2102, 2105, 2106, 2107

Most often, a malfunction of the heater radiator is detected when a puddle of antifreeze or water forms under the feet of the driver or front passenger, or when you turn on the heater in winter, instead of warm air, you get a stream of cold air, and again a puddle of antifreeze in the cabin.

The reason for this is a leak in the car's heating system. The result of such a malfunction is a spoiled mood and cool temperature in the cabin. This problem can be easily corrected on your own. For some VAZ models it will take very little time - VAZ-2101, VAZ-2102. Replacing the stove in a VAZ-2105, 2106, 2107 will require more fuss; repairing the heating system on these cars is not much different, but things are a little more complicated with the radio panel. In this article you will find useful information and guidance on replacing the heater radiator of VAZ cars.

Other problems with the heating system

Although heater radiator breakdowns occur most often, there are other malfunctions that can be easily fixed with your own hands:

  1. Fan motor failure. Problems are created by the rotor bushings, which on the “original” motor are made of low-quality material. As soon as the heating system fan begins to whistle, it needs to be replaced with a non-original one, in which bearings are installed instead of bushings.
  2. Heater valve wear. It suffers from scale, dirt, and simply wears out. Cranes are usually not repaired, but replaced. It is better to replace a faucet with a ceramic core; it is much more reliable and durable than a metal one.
  3. Breakage of control unit rods. Everything is clear here: what should be regulated is not regulated - check the condition of the rods and their connection. Sometimes the problem is solved in just half an hour.

More complex work, such as tuning or modifying the stove, is no longer considered troubleshooting. Of course, the stove on a VAZ opens up endless possibilities for improvements and additions, but you can get by with what you have at the moment. The main thing is that everything works as it should, and then you definitely won’t freeze in winter.

It is better to check the heating system before the time comes to use it. In the summer it is more comfortable and easier to do repairs; you can take your time and look for high-quality and inexpensive spare parts, and generally come to the cold season fully armed. In most cases, when the VAZ 2107 stove does not heat, you can correct the situation yourself. You just need to have straight hands and the desire to do the repairs correctly and efficiently.

Replacing a stove radiator for a VAZ-2101, VAZ-2102, VAZ-2106, VAZ-2107 car

Motorists o. stove radiator (insulation), often mentioned only in autumn. winter. No, there are times when people mention this before. For example, the unexpected appearance of antifreeze or water (depending on what is poured into the cooling system) under the feet of the driver or front passenger. The cause of this phenomenon is leaks in the car's heating system. But most often the driver finds out about the malfunction of the heater radiator only with the onset of cold weather. When you want warmth and comfort in the car. Pull the oven switch knob in the heat direction, turn on the fan, and then instead of a blast of warm air from the ducts, you'll get a blast of cold air or another option. form a puddle of antifreeze. in the cabin. And as a result. bad mood and cool, uncomfortable atmosphere in the car.

But everything can be fixed (for any car) and in a very short time (this is a question for VAZ-2101 and VAZ-2102) Mainly replacing the heater radiator and other problems with heating system malfunctions on other Lada models. VAZ-2105, VAZ-2106, VAZ-2107 is a little different, a little more cluttered with a radio panel (panel), but this article will describe the process of repairing the heating system and replacing the radiator furnace VAZ-2101, VAZ-2102 cars.

Causes of heating system malfunction:

  1. The reason for the appearance of antifreeze in the cabin may be a rusty stove radiator or a metal pipe in the stove faucet. You can determine the exact cause by visual inspection. If all the problems are hidden, for example in a faucet or pipe, they can be replaced without disassembling the radiator body and core panel. If the radiator is responsible for the coolant leak, there are two options to solve the problem. Firstly, if you installed a copper radiator (old model), it can be repaired, cleaned, sealed, preserved, etc. The main thing. find a master. The radiator is working. The second option is that you installed an aluminum stove radiator. Everything is simpler here, it is better to replace it with a new one, it cannot be repaired.
  2. When you turn on the heater from the ducts, cold air continues to blow. The reason is a violation of the circulation of coolant in the car system through a faulty heater tap (it is constantly closed) or a clogged radiator itself. If the faucet is stuck, it needs to be replaced, but paragraph 1 of this article will help us choose the right radiator solution (see above).

They understood the reasons. Now the main thing is How to change the stove radiator for a VAZ-2101, VAZ-2102, VAZ-2105, VAZ-2106, VAZ-2107?

Necessary tools. a pair of screwdrivers (Phillips and regular), socket and open-end wrenches for 7, 8, 10. You also need to buy rubber gaskets (three pieces), a liter of coolant, and silicone sealant.

Repair

After the diagnostics have been completed, you can begin troubleshooting.

If the coolant level drops, it is necessary to find the location of the leak and eliminate the leak. Then add liquid until the neck is full. Then remove the air plug from the cooling system by pushing through the rubber pipes with the engine running, and add fluid if necessary. To replace the thermostat, you need to drain the coolant, unscrew the thermostat cover and replace it with a new one. Then fill in coolant and get rid of the air lock, as described in point No. 1.

To “break” a soured faucet, you can try to turn it manually (without a cable drive), and if it does not turn, you need to dismantle it and replace it with a new one. To do this, it is not necessary to drain the coolant; it is enough to clamp the pipes before and after the tap. You can try to lubricate a soured valve “remotely” by spraying water-repellent grease onto the hinge joint. If this procedure does not bring results, then you need to dismantle the entire heater and “develop” the damper. You can clean a clogged radiator by rinsing it with a special liquid or running water. But this will only help clean the inside, and the outside will remain clogged, so to achieve the maximum result from the work done, you need to remove it and wash it both inside and outside. If flushing does not produce results, then you need to replace the radiator with a new one.

Before replacing, it is advisable to flush the entire cooling system, otherwise this replacement will have a positive effect in a short time

The body is fastened together with iron brackets; it is important that they all stand in place and tightly press the parts of the body to each other. The radiator must be sealed in the housing around the perimeter to prevent flow from passing through the honeycombs

It is better to use foam rubber for compaction. After checking the fuse and wiring of the fan, you can begin to dismantle it. Then assess the feasibility of repairing this unit. Before final assembly, you need to connect the motor to the standard wiring and check the functionality on the car. The fan impeller is made of plastic and can be damaged with slight force, so special care must be taken during assembly.
