Modern vehicle - a complex system of interrelated elements. However, even people fairly far from engineering, understand the purpose of cooling the radiator - it removes excess heat from the engine, thereby preventing it from possible overheating.

But, under the influence of time, cooling the radiator, as well as any other element of the vehicle may be damaged. In this case, there is a need for its replacement. You can do this in two ways - by resorting to professional help or on their own. Undoubtedly, the second option requires less financial costs, but much more time and patience. In any case - the choice is only yours. And if you decide to replace the heat sink on their own, read on the article detailed instructions.

radiator device

Any car radiator, regardless of brand, consists of:

1. Core.
2. Connections.
3. Two halves (corpus).
4. Drain cock in the lower housing section.
5. Filler plug in the top of the radiator section, complete with valves - an outlet and an inlet.

The body is made of aluminum or copper (most often from aluminum), consists of two tanks (from above and below) and the nozzles adjacent to them, according to which the coolant circulates. Inside the case there is a core - rows of brass tubes that are soldered with cooling edges. In the radiator, the cooling fluid falls through the bay stop, and by means of a drain crane, respectively, if necessary, merges.

In addition, to maintain the temperature regime, the temperature aggregate includes a temperature sensor (2) and an electric fan (1).

Cooling system does not work well, causes and ways to eliminate

1. Clogging of radiator nozzles. This phenomenon, today, occurs very rarely, and that - only when using poor-quality coolant. In this case, replace nozzles.
2. Low coolant level as a result of cracking in nozzles or leakage in places of their attachment.
3. Pollution of the case. Here it is necessary to take into account one small detail - for the whole car, the radiator - in particular, care is needed. Do not let it "figure out" with fallen leaves, mud and other garbage, as it significantly reduces the effectiveness of its work.
4. There is another reason for the failure of the cooling system - the appearance of leaks in the radiator. Remove it so that in the place of the leak, its size and general wornity of the device, decide, is needed to replace it or repair.

Tools, fixtures, consumables for replacing radiator cooling VAZ 2110

1. Flat screwdriver.
2. The key to "10".
3. New radiator.
4. Antifreeze.
5. Capacity for drain.

Cooling radiator VAZ 2110, what to choose, aluminum or copper, comparative analysis

Advantages and disadvantages of an aluminum radiator:

Relatively cheap, light, cost depends on the manufacturer:

1. Pramo (2110-1301012) - about 1600 rubles.
2. Luzar (2110-8101060) - approximately 1000 rubles.

It has a smaller thermal conductivity, less efficiently cools the motor, is subject to enough corrosion. To the aluminum radiator of the flow, you need much less time.

Advantages and disadvantages of the copper radiator:

It is heavier, more efficient on cooling characteristics, serves longer, since the copper case is less susceptible to corrosion. In order for the copper unit, the flows, as a rule, a mechanical impact is required (for example, a blow and so on).

The disadvantage is a big value. For a double-row radiator with an increased efficiency, 40 percent will have to put 5,000 rubles.

Cooling radiator, how to dismantle the old and install a new

1. Remove the battery so that it does not interfere with the dismantling.
2. Next, remove the ignition module to merge the coolant.
   
3. We merge the cooling fluid in a pre-prepared canister.
   
4. If the car is equipped with an injection system, you must remove the air filter.
5. Then we turn off the wires going to the fan, for which you should disconnect the branded block on the fan and cut the clamp that fixes the harness.
   
6. Now you need to free the throttle of the throttle, which is fixed on the fan casing.
7. Remove the nozzles of the cooling system from planting fittings of the thermostat, pre-weakening the clamp.
   
8. Next, you need to disconnect the steaming nozzle, which leads to an expansion tank from the radiator. Remove the clamp.
9. From the fixing clamps, we remove the vocabulary nozzle. These clamps are usually located at two points - on the water pump pipe and the expansion tank hose.
   
10. Next, you need to disassemble the upper mount of the radiator to the car frame.
11. Take out the radiator from the car.
    
12. Disconnect the fan from it and all the hoses (removing, applying and vapor), for which you should weaken the tightening of the clamps.
13. Remove the landing pillows from the lower pins and we estimate their condition. In the presence of cracking or deformation - we produce their replacement.
    
14. To determine exactly where the radiator flows is supplied to the air pressure has no more and 0.2 MPa is immersed in water. However, it is better to entrust it to professionals.
15. Before mounting a new or repaired radiator, check the state of the rubber sleeve on the upper mount. If she is worn - change it to a new one.
16. We carry out the installation of the fan.
    
17. Do not forget to wear lower mounting pillows on the pins of the radiator.
18. The last stage is the fill of antifreeze into the system.

Profi advice, why when choosing a new radiator you need to know the model of the old

When buying a new radiator, be sure to check how your vehicle is equipped with your vehicle, since the radiator model, as a rule, depends on the volume of the power unit and there is both a new and old sample.
