A modern car is a complex system of interconnected parts. Violation of the normal operation of any of them will ultimately lead to breakdown of several others. A good example for such a statement is the case of a radiator breakdown.
The cooling system radiator is one of the most vulnerable parts of a car. With a thin brass body with a large number of soldered joints, it is more prone to mechanical deformation than any other part. And in simple terms - a breakdown from the blow of an accidentally flown pebble or tree branch.
The second common cause of radiator breakdowns is the destruction of soldering points and resistance welding. It is in this case that the mutual influence of the elements of the car has a destructive effect: long-term operation chemically weakens the contact zone, a violation of the pump or thermostat operation mode increases the temperature of the coolant, the bonded valve of the lid does not allow the pressure to be relieved in time, and as a result, we get many points of leakage.
There are many more reasons why the radiator may need to be repaired, but this is already a topic for another very voluminous article, and in this review we will briefly tell you how to properly remove the radiator of the cooling system of a VAZ 2110 car if a leak is suddenly found.

- heater radiator;
- coolant drain hose from the heater radiator;
- coolant supply hose to the heater radiator;
- coolant pump hose;
- expansion tank hose;
- heater radiator steam hose;
- expansion tank;
- liquid level sensor in the expansion tank [Installed on parts of cars.];
- thermostat;
- coolant drain hose from the engine radiator;
- hose for supplying fluid to the throttle assembly;
- engine radiator steam hose;
- hose for supplying fluid to the engine radiator;
- engine radiator;
- radiator drain plug;
- electric motor radiator fan;
- coolant pump;
- inlet pipe to the coolant pump;
- coolant drain hose from the throttle assembly.
Removing and replacing a radiator:
1. The battery will interfere with disassembly, so it must be removed.
2. To drain the coolant, remove the ignition module. Now, having access to the plugs on the cylinder block and on the radiator, we drain the coolant into a previously substituted container. 3. If the vehicle is equipped with an injection system, the air filter must be removed.
4. Disconnect the wires leading to the fan. To do this, disconnect the branded block on the fan and cut the clamp that secures the harness.
5. We release the throttle valve rod, which is attached to the fan shroud.
6. Having previously loosened the clamps, remove the cooling system pipes from the thermostat mounting fittings.
7. Disconnect the steam outlet from the radiator to the expansion tank at the point of attachment to the tank. Remove the clamp.
8. Remove the steam outlet from the clamps fixing it. Typically, these clamps are provided at two points. The first on the expansion tank hose.
9. The second is on the water pump pipe.
10. We disassemble the upper mount of the radiator to the car frame (this way we simultaneously release the fan).
11. We take out the radiator from the VAZ 2110 car. In order for it to "come out" without any problems, it is necessary to tilt it towards the engine.
12. Disconnect all hoses and fan from the removed radiator. To do this, loosen the tightening of the clamps and disconnect from the radiator hose No. 1 (outlet), hose No. 2 (supply) and No. 3 (steam outlet). Then unscrew two bolts and nuts.
13. If the landing pads remain on the lower pins, remove them and assess their condition. In case of deformation or cracking, we change to new ones.
After that, the removal of the VAZ radiator can be considered complete. Now we determine where to flow in the radiator by supplying air with a pressure of no more than 0.2 MPa into it and immersing it in water. But the right decision would be to entrust this procedure to professionals. Although there is nothing difficult here.
14. Replacing the radiator 2110 of the VAZ car model with a new one occurs in the reverse order. But, before installing a new or repaired radiator on the car, we check the condition of the top mount rubber bushing. In case of wear, we change it to a new one. We install the fan by fixing its casing.
15. Install the radiator in the workplace, following all the points of this manual in reverse order, but initially do not forget to put on the bottom mount pillows on the radiator fonts.
16. The very last step in replacing the radiator will be pouring antifreeze (antifreeze) into the cooling system. To do this, read in detail the article entitled: "Replacing the VAZ 2110 coolant".
