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 may fail or work with low performance if there are air 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;
- turn over the three screws with which the stove radiator is fixed;
- we take out the radiator from the heater housing;
- weaken the hose mounting clamps and remove them from the heater radiator nozzles;
- if necessary, clean the device from dust, dirt, extraneous garbage.
Installing in reverse sequence.
Very often, to reduce the sound of the fan of the stove, producing it, change it to a more perfect model

Step-by-step radiator VAZ 2109
To replace the radiator, you need:
- Keys for ten and eight
- Flat screwdriver
- New radiator
- Sudine for the drain of coolant
- New coolant
And so start the replacement of the radiator.
1. Remove the minus terminal from the battery. If you just went, wait until the motor cool down. Next, remove the crankcase and open the heater crane. Also open the lid of the expansion tank. Remove the drain plug, and drain the entire coolant in the pre-prepared vessel.
2. Disconnect 2 wiring from the electric fan sensor. Next, turn off the fan wire connector. Now disconnect all the hoses from the radiator. To remove the hoses, you need to make climbing clamp before removing. Next, unscrew the 2 nuts fastening nuts on top of the fan casing, and then remove the radiator fastening bracket.
3. Remove the radiator (in a compartment with a fan housing), slightly tilting it to the motor. Fit fan housing on four bolts. Remove the bolts and remove the fan body. I advise you to look at the condition of the pillows, they are on the lower mounting of the radiator. If they are damaged, I advise you to replace.
4. We take a new radiator and put the fan case on it. Next, set the pillows to the bottom mount. Now we take the radiator and carefully we start it and lower it on the pillows into the bracket holes. Next, fix pillows with pins. Now connect all hoses and wires. When the fan sensor is connected, insert protective rings from rubber into its body, and only then the tips themselves themselves.
5. Check the fixing of all hoses and look shielded by a drain plug. After checking, fill the new cooling fluid. Next, connect the battery.
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. We unscrew the fastenings of the radiator to the body and remove the radiator and the fan body from the engine compartment 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 a radiator. Radiator mount on VAZ 2109 Designers Determined in motor 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 B. 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 aerial traffic. 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 It is always accompanied by the knowledge of the design features of the vehicle. In addition, it makes it possible to save well, because the price for repair and diagnostics in a hundred is quite high.
Radiator VAZ-2109 is composite element Cooling systems (CO) serving to create and maintain the optimal temperature mode of the engine. The safety of the engine and the car depends on its sustainable function. The cessation of cooling fluid circulation (coolant) caused by a radiator's flow or failure of another system element leads to overheating and breakdown. Stable work Cooling systems makes it possible to ensure a unique heat of heat from the parts of the operating engine, without which its normal functioning is not possible.
Design and technical characteristics of the radiator
On the VAZ "nine" there is a liquid, hermetic cooling system with forced circulation. Cooling antifreeze occurs in the radiator located in front of the engine compartment. The system's tightness is provided by setting 2 valves in the lid of the expansion tank. When the pressure is raised above 1.1 kg / cm², the outlet valve opens and thereby supports the value of the parameter in the range of 1-1.1 kg / cm². This allows you to increase the boiling point of the coolant to 110 ° C.
If the pressure in C reduced to 0.03-0.13 kg / cm² below atmospheric on the cold engine, it opens inlet valve. When you align the parameters, the latter closes. The cooling radiator of the VAZ-2109 is an element with consisting of 2 vertical plastic tanks, interconnected in a height of 2 horizontal rows of aluminum tubes. To increase the area of \u200b\u200bthe heat grower on them, cooling plates are pressed. The left tank is divided by a horizontal partition to change the flow direction.
The coolant is fed through the nozzle located in the upper part of the radiator, and is given through the lower. The right tank has a switch-switch that controls the radiator fan. At a fluid temperature, about 100 ° C includes an electric motor, and at 95 ° C - it turns off. The radiator is installed in the frame. The casing is fixed on it with a fan installed. The frame of the radiator of the VAZ-2109, in turn, is attached to the car construction of the car.
Filling the system of coolant is carried out through the expansion tank. Constructive feature The "Nine" radiator is the lack of a fuel neck. In order to avoid injury, it is forbidden to open the tank cover and carry out a liquid plot on the hot engine.
Causes of device replacement
If the temperature of the coolant increases during operation and the level does not decrease, then, most likely, problems with the radiator arose. Since the tubes are aluminum, and their diameter is small, they are not subject to repair. Today, the auto routes offer various additives soluble in coolant, and tamping fistulas. However, it should be remembered that their use is a temporary measure. During the trip, the fault may arise again and lead to difficult consequences.
Most often the leaks of the radiator occur due to mechanical damage to plastic tanks and cooling tubes during accidents or repair work in the engine compartment. With this defect to restore it is impractical. In this case, it is recommended to replace the engine cooling radiator to a serviceable one.
To make sure that the device is not sealed, it is immersed in a bath with water, pre-fueling the holes, and compressed air. According to the presence of bubbles that have appeared about the place and degree of damage. During the operation of the car in the winter and in rainy weather, the radiator is contaminated, especially at the bottom. It significantly worsens the cooling of the fluid, which adversely affects the engine operation. In the mud, aggressive substances are reacted with the material of the tubes, as a result of which the fistulas appear.
The use of poor quality antifreeze can not only lead to the failure of the radiator, but also cause damage to other elements of the cooling system. It is not recommended as a coolant to use water, because on the inner surfaces of the shirt of the cylinder block, water pump and the radiator tubes appears scale. It leads to a deterioration of the heat unit, which negatively affects the operation of the engine.
For efficient operation, it is necessary to periodically make it washing and replacing the coolant. This will help to avoid breakdowns and extends the service life of the system elements.
Step-by-step instruction for replacing the radiator
If there are some skills, you can remove the radiator with your own hands. If the car enthusiast does not have repair experience, then this work is better to charge a specialist. Before starting disassembly, it is necessary to prepare a container for spent antifreeze. It is not recommended to drain it on earth, because liquid is toxic and you can harm the environment.
To replace the VAZ-2109 radiator, you must perform a series of consecutive actions:
- Disconnect the battery and remove it from the engine compartment.
- Merge coat. To do this, unscrew the plugs on the radiator, the cylinder block and open the heater valve. Works are carried out on a cold engine.
- On the "nine" with an injector, it is necessary to further remove the air filter housing.
- Disconnect the contact pads from the fan engine and the switch sensor and cut the clamp that is attached to the wiring harness.
- Dismantle a bracket traction throttle valvefixed on the fan casing.
- Disconnect the rubber pipes from the shirt of the cylinder block, the thermostat and the steaming hose, removing the fastening clamp.
- Unscrew the nuts fixing the radiator to the car body.
- Extract it to the outside with the cooling fan
After that, the hoses from the radiator nozzles and the remaining equipment are removed.
If during the disassembly, the pillows of the lower fastening were removed, they must be installed in place, and if there are cracks or loss of elasticity - replace. On this work on the dismantling of the defective radiator is considered to be finished.
