In simple terms, the cooling radiator is designed to remove excess heat from the power unit. That is, it serves to protect against engine overheating and does not allow the engine to fail.

But over time, under even the most gentle operating conditions, the radiator can fail. Some are trying to repair it, although in fact the repair will only give a temporary effect, allowing them to get to the service station under their own power. The best option is replacement.

Design

Diagram of the engine cooling system
The structural elements of the cooling unit being considered today are:

• Two body parts;
• Pipes;
• Cores;
• Drain valve located at the bottom of the housing;
• Filler plug at the top of the housing with two valves (inlet and outlet).

Also in fairness, it is worth including a thermostat and an electric fan in the cooling system, which play an important role in cooling the engine.

1. The housing consists of two tanks with adjacent pipes through which coolant passes.
2. The core is a series of brass tubes that are soldered to the cooling fins. They can be found inside the case.
3. The fill plug allows coolant to be redirected to the radiator, and the drain valve allows the coolant to drain when needed.

Replacing a radiator on a VAZ 2110

Replacing a VAZ 2110 radiator with 16 valves is simple; you can use the instruction manual or consult a specialist.

Step-by-step instructions that will help you achieve the desired result:

1. Using the bottom plug, drain the coolant;
2. Remove the battery from the seat, as it will interfere with the replacement;
3. In the case of an injection engine, it is necessary to remove the air filter;
4. It is imperative to disassemble the upper fasteners of the frame, release and dismantle the electric fan;
5. Remove the steam inlet and outlet pipes;
6. The radiator can be removed without unnecessary damage; to do this, you need to tilt it slightly to the side of the power unit;
7. If small leaks appear without visible corrosion damage, it is possible to repair the radiator, but this is a risky endeavor, because the part, even after a very high-quality repair, can cause many problems;
8. When installing new equipment, you should pay attention to the condition and appearance of the rubberized cushions necessary to support the lower part of the radiator housing. It is important that these pillows fit firmly into the holes located along the crossbar;
9. Fill the system with new cooling, connect each pipe, install the battery in its place, tighten each plug one by one, check the fasteners on which the VAZ 2110 radiator frame is secured. Only after a complete check can you try to turn on the engine and check its performance, followed by a check replaced cooling element.

Although replacing the cooling radiator of a VAZ 2110 is a simple procedure, we absolutely must not forget about the subtleties, nuances, safety precautions, as well as consistency in work. Or you can simply go to a car dealership and entrust the replacement to specialists.

Why does the engine overheat?

The engine on a VAZ 2110 can overheat for various reasons. The first priority is a decrease in the efficiency of the cooling system. Why does it stop working properly?

1. The cooling system pipes may become clogged. Today such a situation is rare. Mainly provided that very low-grade coolant is used for CO. There is only one way out - change the pipes and use normal coolant.
2. Various smudges and leaks lead to a decrease in the coolant level. Here you will have to replace all the components that are causing the leak.
3. The housing is dirty. Over time, debris, dirt, leaves, insect corpses, and so on accumulate on the radiator housing. This negatively affects work efficiency. Therefore, be sure to periodically clean the exterior of the housing.
4. Radiator leak. In such a situation, you will have to remove it, assess the extent of the damage and decide whether to repair it or replace it with a new one.

Self-repair of VAZ 2110 radiator

Sometimes situations arise that it is impossible to do without radiator repair work, when you have to take everything into your own hands.

What and how to attach the radiator to a VAZ 2110 is described in the section on replacing the device; a mandatory action is to drain the cooling after the engine has completely cooled. Hoses, clamps, fan, radiator frame 2110 all must be properly disconnected before repair.

Sealing

In this case, you should have the necessary skills in this area and have special equipment. Before starting work, you need to clean the radiator from accumulated dirt. When soldering a small crack, it is enough to make a small seam, which cannot be said about a hole; a plate of the appropriate size will be required; if the tubes are damaged by more than 10%, it will need to be replaced.

Using a recovery agent

Minor damage to the heat exchanger can be repaired by using special products. And so, when repairing a VAZ 2110 radiator, sealant or reducing powder can become indispensable assistants to get to the place of a full inspection and repair. But of course, in this situation it is better to use “cold welding”.

Many car enthusiasts decide to replace spare parts from one car with another, trying to solve an existing problem or save money. And therefore, to the question: will a radiator from a VAZ 2110 fit on a VAZ 2114 - definitely not. The fact is that the radiators of these models are not only different in size, but also have different fastenings.

Choosing something new

Before removing the cooling radiator from your VAZ 2110, you need to think about what unit will be in its place. There are not many options, but the choice should be made wisely.

Kraft model

For the domestic “ten” there are two types of cooling devices - aluminum and copper . And here it is important to think about what exactly you want - reliable, long-term operation, or minimal financial costs for its purchase.

1. Aluminum. They are light in weight and quite cheap. Prices directly depend on the manufacturer. But such radiators have poorer thermal conductivity and do not cool the engine as effectively. Plus, aluminum units are characterized by the appearance of corrosion after a short period of operation. Among the most popular models, we note two: Luzar. Its cost is now about 1000 rubles;
2. Pramo. You will have to pay about 1600 rubles for it.

Causes of engine overheating

The reasons for overheating of the VAZ 2110 engine include, first of all, the insufficiently efficient operation of the cooling system. The reasons may be:

1. The radiator pipes are clogged. A thing that is rarely seen today, and only when using coolant of extremely low quality. In this case, replacing them will help;
2. Low coolant level due to leakage at the attachment points of the pipes or cracks in the pipes themselves. Need to replace fasteners or pipes;
3. Housing contamination. Here you should take into account a small detail: the whole car, the radiator in particular, requires care. It should not be allowed to “overgrow” with dirt, fallen leaves, or other debris. Because of this, the efficiency of its work is significantly reduced;
4. The radiator is leaking. It is necessary to remove it in order to decide based on the location, size of the leak, and general wear and tear of the unit whether it needs repair or replacement.

How to fix problems

Now let's talk about eliminating these faults according to the list presented.

1. Coolant cannot disappear with the wave of a magic wand; it does not evaporate under the influence of temperature. Therefore, you need to check all pipes, hoses, clamps, radiator and other components. There is bound to be damage somewhere causing a leak.
2. If in winter you have to stand still for a long time waiting for the engine to warm up, try insulating the engine compartment. There are many ways to do this - from the classic “sheep coat” for the engine, to using simple cardboard in front of the radiator in winter, or using special insulation. Be sure to ensure that your insulation does not touch the generator belt.
3. In the event of detonation, we can only sympathize with the car, since its owner completely ignored all the signals from the car that the CO was in a faulty state. If the simplest repair measures give a positive result, consider yourself very lucky. If not, then engine repair cannot be avoided. And these are completely different amounts of money.
4. When the sensor needle is in the red zone, immediately take appropriate measures. Turn off the engine to prevent excessive overheating from leading to even worse consequences. Raise the hood and check for fluid in the reservoir. Just don't open it, it's very hot in there. With a timely reaction, you can avoid boiling and whistling from under the hood. But it’s better not to drive to the service station on your own. Call a tow truck.
5. Situations where engine head gaskets break are not uncommon. But we don’t want anyone to encounter them. Such a breakdown indicates that you must begin a full engine repair. On your own or at a car service - decide for yourself.

Reasons for failure of the cooling radiator

As a rule, the main reasons for the failure of the cooling radiator are:

• mechanical damage;
• vibration;
• corrosion.

Often flying stones damage the radiator, jamming its thin “honeycombs”. Also, vibration loads cause cracks to appear in different parts of the radiator.

To increase the service life of the radiator, it is necessary to monitor the cleanliness and serviceability of the cooling system. It is recommended to periodically flush the entire system, regularly change antifreeze, do not pour ordinary untreated water from the water supply into the system, and also clean the radiator externally from dirt, dust and fluff.

What to do next

To replace the old VAZ-2110 radiator with a new device, repeat the above in reverse order, starting from the last point. In order for the radiator to work well, it is also worth checking the condition of the rubber bushing on the upper fastener. If the part is very worn, replace it with the one you just purchased.

The subsequent steps to install a new product are as follows:

• fix the air ventilation device;
• tighten the casing well;
• place the radiator in its original place in the VAZ-2110, put the lower mounting pads on the pins;
• When the radiator is already standing, add antifreeze.
