How to replace the cooling radiator on the VAZ 2109. Replacing the cooling radiator with its own hands. Causes of device replacement

Over time, all the systems of the car are out of order. And the radiator of the engine cooling system under the influence of external factors (stones from vehicles or branches protruding from the Earth) fails.

In this article, you will learn about how to replace the radiator VAZ 2109 and in general the whole family "Samar" with their own hands.

We will need:

- Looking Yama

- screwdriver

- Tosol or antifreeze, well, or any automotive coolant

- spanners

- Empty capacity

- New radiator

- high temperature silicone sealant

We proceed to self-replacement of the radiator VAZ 2109

1. We throw off a "minus" terminal from the battery and wait until the engine will completely cool.

2. Remove the protection of the crankcase and remove the lid of the expansion barrel.

3. We unscrew the drain plug on the radiator (on the radiators of cars VAZ 2109, 2108, 21099, it is located in the lower right corner) and drain the entire cooling fluid into a pre-prepared empty container (the volume of cooling fluids is approximately 5 liters so that select the appropriate container).

5. If the car with the engine is engine, then for self-substitution Radiator VAZ 2109 Additionally, it is necessary to remove the air filter.

6. Disconnect all the nozzles suitable to the radiator.

7. Remove the fastenings of the radiator to the body and remove the radiator and the fan body from motor compartment Machines up, with a slight tilt toward the engine.

8. Remove the nut and three fan bolts to the radiator. It is necessary to check the condition of the radiator pillows located on the lower fasteners. If they are torn or lost elasticity, they must be replaced.

9. To install a new radiator, it must be put on the lower fasteners and attach the fan to it. Next, all previously removed hoses are properly smearing their sealant and tighten the clamps.

10. Connect all previously disconnected wires.

11. Pour a new cooling fluid and wait for 10-15 minutes before graspting the sealant.

12. We start the engine, open the heater's crane and give it a little to work a little so that the coolant filled the entire system. At this moment, do not forget to monitor the level of the coolant in the expansion tank and felt as needed. For a full-fledged air outlet from the cooling system, which appeared there after replacing the radiator, it is necessary to raise it as above before the car and give it to work so much 10-15 minutes.

13. Spin the plug of the expansion tank.

On this, the replacement of the radiator VAZ 2109 is finished with their own hands! Good luck to all!

My blog is found according to the following phrases.

The main constructive feature of the engine cooling system motor vehicle is the radiator. Mounting of the radiator on the VAZ 2109 Designers were determined in the engine compartment.
It is located behind the decorative front grille of the car. On the VAZ 2109, the fastening of the radiator has a special device for heating.

Basic design features

So:

At the bottom of the radiator, the pins are designed in which inserts from rubber are installed. These inserts are responsible for the depreciation of the radiator during the movement of the vehicle.

In the lower part there is a pipe with a thread, a plug cork is twisted into it.
If you look at the front surface of the radiator, the right in the middle is space for installing the fan power sensor.
In the upper part two cylindrical protrusions are provided for connecting rubber pipes.
At the bottom - one protrusion.

Radiators are made of aluminum or copper alloys. Since such alloys are less subjected to oxidation in interaction with disintegration fluids.
So:

On the front there is a surfing transverse chaserler. It provides holes for installing rubber inserts. They are inserted there in space.

Note: Therefore, before installing them, it is necessary to moisten in the soap solution.

Insert inserts must be carefully so as not to disturb the rubber structure. Since the edges of the chapellery have sharp surfaces.
On the installed inserts it is necessary to tap the engine to the engine gently put the radiator on the pins.

After that, the top of the radiator bends to the front decorative grid.
Under the top transverse channel there are two studs that are welded to the body.
The metal spacer plank is screwed on them.
The top of the radiator is attached to this bar.

Note: A rubber gasket is paved before the bar.

Two nuts secure the top of the radiator.

This method provides for the fastening of the system radiator.

Device heating salon

Designers of manufacturers plants provided for the installation of the radiator of the heating system of the car VAZ-2109 car. Under the auxiliary device panel, which is between two front seats, the design is provided by the location of the stove of the interior heating.
It made a frame for installing the radiator. Plastic protective panels are installed on this panel from both sides (passenger and driver).
They are attached to four self-pressing:

Unscrew the screws.
Remove them.
So dismissed access to the radiator of the salon heating.
It is fixed on four self-drawing.
They are installed in the holes located on the upper, lower surface of the radiator.
Split screws.
After that, connect the hoses of the salon heating system.

Note: Before stretching nozzles, you need to wear fastening clamps.

Tip: Before installing the clamp on the inner edges, clean the sandpaper. It is necessary to do this in order to remove sharp edges.
Since sharp edges can damage the rubber surfaces of the nozzles.

This provides for the constructive order for fastening radiators on VAZ-2109:

Tip: It should be borne in mind that before fixing the upper part of the cooling radiator, it is necessary to establish the upper pipes on it.

Secure them with clamps.
Only then kpi the top bar to the vehicle body.
The next procedure for bringing the cooling system to the operating status.
Install the bottom nozzle and spin the clamp.

Note. The lower nozzle will easily install from the observation pit. Previously, you need to remove the protection of the engine crankcase.

Assembly and checking the cooling system

It is necessary:

Install.

The fan casing is attached to the radiator with two bolts on the right side. On the left side gently dresses on the studs, fastened with nuts.

Then insert the power supply terminals of the cooling engine.
Check the drain plug tight.
Stretch clamps on installed pipes.
Check the tap for the salon heating, it must be open, the lever handle must be in the extreme right position.
Only you need one hose that passes on the carburetor to remove.
Pour Tosol into the expansion tank. It is necessary to pour carefully, look at the fitting of the carburetor.
As soon as Tosol flows out of it, put the pipe, tighten the clamp.
Add to the tank to the level between the minimum, maximum marks.
Close the plug of the expansion tank.
Start the engine.
Leave it to work for 2-3 minutes.

At this point, the system is filling, removal of air traffic jams. In case of poor warming, you need to drown out the engine.

Open a tank stopper.
The top nozzle to the engine block wrap with a rag.
Make a few sudden push on it.
Air bubbles should appear from the tank.
Then close the tank again.
Turn the engine.
Wake out for 5 minutes.

The engine must warm up. Lower nozzle as well. The temperature of the device must show 85-90 0.

Conclusion: Checking the engine cooling system on this can be considered complete.

It is necessary to carry out all the work related to the verification of the work of the motor vehicles with your own hands after watching the video. It is necessary to view, carefully examine the written accompanying instructions.
Get acquainted with the included photos.
Independent holding maintenance Always accompanied by Knowledge constructive features motor vehicle. In addition, it makes it possible to save well, because the price for repair and diagnostics in a hundred is quite high.

Cars VAZ 2109, 21099 are equipped with injectors and carburetors. At the same time, both versions of the car have a cooling system.

How it works

The principle of operation of the cooling system (CO) is as follows:

The pump drive functions from the timing belt;
The system has a volume of 7.8 liters, if taken into account the stove;
The temperature is controlled by the sensor installed in the shirt of the cylinder block. Temperature readings are displayed on the dashboard;
When the motor is running, the liquid from the shirt goes into the radiator (heat is selected) or to the thermostat (work on the small contour required to warm the engine);
Then, the cooling fluid with the pump goes into the engine cooling shirt (injection);
At the expense of pipelines, coolant circulates on the system;
The CO uses a centrifugal pump;
Radiator applies tubular-plate, collapsible, equipped with plastic expansion Bachkom;
Inside the radiator has aluminum tubes and cooling plates, but no bay hole;
For fill and tall, the extension tank is used. There is also a fan switching sensor;
The tank is equipped with a fuel throat, intake and exhaust valve;
To merge the coolant from the system, you need to unscrew the drain plugs on the tank, the radiator and the cylinder block.

If you understand in detail in the components of the cooling system and their functions, features, you will be able to carry out repair, preventive work, change the radiator or individual components of CO.

Elements of S.

The cooling system used on the VAZ 2109 works under a slight pressure. After examining the components, you will learn about their functions and features.

Element	Features
	It provides efficient, stable work Systems. The pump serves to pump the cooling fluid, which contributes to its movement on a small or large contour. Pump consists of a housing, an axis with a pulley located on it connecting with timing beltand plastic impeller. The latter makes it possible to move. A bearing lubricated to Tosol is installed between the axis and the housing. Because of this, the presence of water in the system is unacceptable. Otherwise, the bearing collapses
	Plays an important role, although in practice I can do without it. The system works so that at first the engine is heated to operating temperature (about 90 degrees Celsius), after which it is required to additionally cool the liquid. First, the coolant moves along a small contour - through a shirt in the stove radiator, and then the surplus returns to the expansion tank. But when the operating temperature is reached, the thermostat begins to move the flow of coolant into the radiator. The thermostat can be called a mechanical valve that automates the work of CO. Hot liquid acting on the bimetallic plate of the thermostat deforms it, because of which the feed valve in the radiator can open or close
Radiators	In VAZ 2109 there are a pair of radiators - stoves and the main one. They have the same design regardless of whether the carburetor is or injector. In this case, there is a noticeable difference between the main and stove radiators. Basic larger in size, they perform different functions, plus the main holes for the sensor turning off the fan. If the stove radiator can be connected to operation at any time by pressing the button, the main radiator operates automatically when certain parameters of working with
Expansion tank with cork	Inside C is maintained constant pressure, which ensures efficient circulation of coolant. On the VAZ 2109, the system is arranged so that at high pressure, the fluid boils without reaching 100 degrees, and at higher parameters. This increases the reliability of the engine. Pressure support is provided by an expansion tank with a lid, a pair of mechanical valves - intake and release. Inlet valve It works if the pressure drops to 0.13 atm. The second is connected to operation at the moment when the pressure turns out to be higher than 1.3 atm.
Pipes, clamps	It is not necessary to underestimate the role of pipes and clamps in CO, since it is precisely the flow of cooling fluid to the desired points. When replacing, in no case use the trimming of other nozzles that do not correspond to the parameters used earlier. Plus if at least one nozzle was damaged, everything is complete, and not separately
	Looking at the radiator (main), below you will see a pair of wires and a yellow-colored device twisted into the hole. It is the sensor switch of the electric fan. Another sensor is also located in the motor block. It transmits information on the electronic unit Control or pointer
Electroventian	Standardly, the VAZ 2109 is installed fans equipped with 4 blades. But if you want to achieve greater efficiency, we advise you to replace it with an electric fan with 6 blades. This will increase the air flow, while maintaining the initial power and speed of rotation. Inside the interior, the heat from the radiator stove begins to come when the crane is opened. Under the hood there is a fan connected via a row. It regulates the frequency of rotation of the impeller. The switch is located under the audio system, near the heater valve control levers.

When planning the replacement of the electric fan, work should be done through podcast space. No need to dismantle snail.

Replacing radiator

The radiator is changed in the event that it appeared to flow. In some cases it can be repaired, throwing the place of the leaks. To verify maintainability or the need to replace the device, it is better to first carry out a small check.

To check, you need to dismantle the radiator, close all the nozzles and place the devices in the bath with water. We bring air under pressure and check. If after 20-30 seconds, bubbles will begin to appear, there are holes in the radiator and they can be found without any problems.

Having gathered with the forces, carry out the replacement.

Disconnect minus with battery or remove the battery.
Drain the entire cooling fluid.
If you have an injection machine, not a carburetor, you will need to additionally remove the air filter.
Cut the clamp that holds the wiring harness. Disconnect the electrical firing pad.
Remove the damper thrust clamp (throttle). It is located on the fan casing.
Disconnect the discharge hose connected to the thermostat.
Disconnect the supply hose. It is connected to the shirt nozzle.
Remove the warehouse hose.
Unscrew the nut that holds the radiator on the body at the top. The same bolt holds the fan casing.
Tilt a little radiator to the engine, remove it, raising up. Dismantling is carried out directly with the electric fan.
Loosen the tension of the clamps and disconnect all hoses going on the radiator.
Unscrew all the fasteners that hold the casing with the electric fan and the radiator itself.
Discontinue the radiator with the fan casing.
Remove from the radiator a couple of lower fixation pillows. Examine the condition of the pillows. If they are worn, lost its original elasticity, it is better to immediately replace with new ones.
Moving in reverse order, set the place of the old new unit. Do not forget about lower fixation pillows.
Fill into the system new liquid cooling.

The engine cooling radiator on the VAZ 2109-2108 has to be changed not so often, and mostly this is due to its leakage. There are of course lovers repair them, that is, to resort to the soldering, but still a more reliable option is a complete replacement.

To perform the removal of the radiator from the car, we will need the following tool:

head at 8 and 10
patty handle
screwdriver Flat and Cross

Instructions for removing and installing radiator on VAZ 2109-2108

Before you begin to dismantle, you first need. Then necessarily. After this is done, it actually remains only to remove the cooling system nozzles. So, two nozzles are at the top, and they are visually shown in the photo below. First unscrew the bolts of the clamps:

After that, remove the nozzle and the hose, the result of which is shown in the picture below:

Then we proceed to the bottom nozzle, also revealing the bolt of fastening the clamp, remove it:

And it remains to be disconnected by two wiring from the temperature sensor, which is on the right side of the radiator. Below it is shown more clearly:

After that, you can proceed to the removal. Gently assign a radiator a little forward to the engine:

And also no less carefully take it up, following it, so that it does not cling to anywhere when dismantling, so as not to damage it:

If necessary, replacing, you need to buy a new one and install in the reverse sequence. The price of a new radiator on the VAZ 2109-2108 is about 1100-1500 rubles and differs depending on the company manufacturer and manufacturing material.

The trouble-free operation of any car is impossible without a cooling system. The main element of this system is the radiator, which is a reservoir made of synthetic material or aluminum, equipped with edges on the left and right side.

Continuous circulation of coolant on special channels, allows you to maintain a certain temperature needed for normal work Engine.

The output of the cooling device is out of order, leakage of coolant, insufficient level, ultimately can lead to engine overheating and ultimately to break it. The radiator of VAZ 2109 can be repaired, after identifying the main reasons that could serve as a refusal of its effective work.

Removing the radiator and its subsequent installation in place, you must perform on cold car engines. Before installing a new or repaired radiator, it should be checked for tightness.

To do this, slightly shook the nozzles, lower it into the bath with water and supply the air with a pressure of 0.2 MPa. If within 30 seconds, bubbles did not appear on the surface, then we can assume that the device passed on the tightness. All work on the repair and replacement of the radiator can be made independently with their own hands, without resorting to the help of a specialist.

Dismantling of the failed cooling system devices in the following sequence. Photos that accompany the entire dismantling process will help to easily and quickly cope with the task:

remove the battery;
we produce a drainage of coolant;

disconnect the electrical fan power sensor wires;

we turn over two nuts and two bolts with which the electrical fan casing is mounted;

unscrewing two fastening nuts, remove the bracket;

disconnect the block with wires by means of which power is supplied to the electric motor of the radiator fan;

tilting the casing with an electric fan towards the engine, take out the fan casing from the engine compartment;

weakening the fastening clamps and disconnect the two upper hoses suitable to the radiator;

disconnect the lower hose;

tilting the radiator towards the engine, take it out;

remove from the radiator of the lower fastening pillow if they have come out with the radiator mounting pins. If necessary, in the case of loss of elasticity and the presence of torn places, we produce their replacement.

Installing the cooling radiator is performed in reverse sequence.

It is worth noting that one of the reasons for continuous overheating of the radiator can serve as its clogging. In this case, it is enough to wash the radiator with a large water pressure.

It costs to immediately check the radiator for tightness

Radiator stove VAZ 2109

With the onset of cold weather, almost all owners of VAZ 2109 are faced with the reasons for this can be a lot, but as one of the mains is the failure of the stove radiator. Then, even at normal coolant temperature of 90 degrees, barely warm airWhich is not enough even for direct heating of windshield and side windows, not to mention the creation of a comfortable microclimate in the car's cabin. VAZ 2109 stove heating device can fail or work with low performance in the event that there is aerial traffic jams. It is possible to judge the presence of such a problem in cold air coming from the cooling system deflectors with a fully open crane. Solve this problem can be enough simple way: Install the front wheels of the car on the elevation, open the stove crane until it stops and pay off.

The discovery in the cooling fluid salon can only speak the rim, the heater radiator lost its tightness and its replacement is required. You can replace with your own hands without resorting once again to help a specialist, it is enough to explore the provided photos and follow the recommendations:

it is necessary to merge the cooling fluid from the cooling system of the car, while the crane on the heater of the cabin must be fully open;
on the right side of the stove is a screw, with the help of which the fastening of the clamp of the thrust adjusting the heating flap windshield - It must be turned away;
