Copper radiator VAZ 2108, 2109, 2113, 2114, 2115, increased performance

In this article we will talk about the cooling radiator on Lada cars of the Samara 2 family. The entire replacement process is described in detail below, as well as prices with article numbers for the purchase of a new radiator.

Cooling radiator VAZ 2114: useful tips for replacement

How is the VAZ 2114 cooling radiator replaced? This question interests many owners of cars of this model, which is a restyled version of the VAZ 2109. The hood and headlights have undergone changes, plastic moldings and spoilers have been installed, and a new VAZ radiator grille has been installed on the car.

Breakdowns happen to almost all cars, the consequences of which vary. If the radiator of a VAZ 2114 breaks down, the car’s engine may overheat and fail. Therefore, you need to regularly monitor and care for this very important device in the vehicle cooling system.

Three main water pump problems

During the operation of domestic vehicles, you can sometimes hear noise and play in the bearings. If damage is detected, you should not drive the car for a long time, otherwise the pump may jam or rupture.
The substance boils away through the hole - this is an alarming signal that indicates rapid wear of the spare part.
A broken impeller means a malfunction; the car’s engine quickly overheats.

Cooling fan: The car engine will also overheat greatly if the fan in the vehicle is not working properly.

Poorly tightened and faulty clamps can cause your personal car to overheat. Sometimes it happens that thin hoses become clogged and therefore the throttle valve heating return flows poorly.

What is a radiator and what is its function?

The radiator looks like a rectangular box made of numerous and very thin slats. Inside, it is a system through which the coolant passes and is cooled by the oncoming air flow. At the end sides of this element there are two pipes to which water cooling hoses are connected.

The principle of its operation is very simple. When the driver starts the car, the engine begins to work, but the harder and longer it does useful work, the higher its temperature. It's no secret that the fuel-air mixture ignites in the upper part of the cylinder blocks of the power unit. Around this zone there are channels through which coolant flows. The water pump accelerates it under pressure and it enters the “hot” zone. Having made a circle and absorbed the heat, it returns to the radiator. And since it is open to air flow, it cools the liquid, which then repeats its cycle many times.

Thermostat problems

When the temperature reaches 95 degrees Celsius, the liquid begins to flow through the thermostat. Due to the operation of this unit, the engine requires a minimum of time and resources to warm up. The thermostat is located between the radiator and the engine.

Most often there are two types of faults.

The valve closes. If the engine is not warmed up, it is difficult to maintain speed. It may simply stall.
The valve opens. During frosty periods, you can operate the car, but you must turn on the heating at maximum speed. Otherwise, the power unit will simply overheat.

If you are unable to move the valve while repairing the thermostat, don't be afraid to lightly tap the housing with a simple screwdriver. This will solve a common problem.

When the thermostat is completely disassembled, the pipes are hermetically sealed, which will prevent coolant leakage. Only after this can you start working.

In general, the choice between antifreeze and antifreeze should not be a problem for you. Choose antifreeze. Although it is more expensive, it lasts longer and allows you to minimize possible problems with wear and tear of the cooling system. The imaginary savings due to antifreeze are not called that for nothing. In the future, you will pay much more to fix the damage caused by the use of antifreeze.

Reasons for removing a cooling system element

When a car breaks down, some reasons lead to the need to remove the radiator. The main ones:

various types of mechanical damage;
individual radiator tubes are clogged with dirt, deposits in the form of scale and rust;
getting a car into an accident.

Replacing the device in question is not always required. Sometimes it can be repaired, washed, soldered. Modern radiators often have an aluminum core and a plastic tray. Such models are very difficult to repair.

To eliminate the malfunction or replace it, you will need to dismantle the device. You need to take this work very seriously and do it carefully. In order for the process to be carried out efficiently, you need to at least briefly know what parts the radiator assembly consists of. It includes:

device body;
expansion tank;
Electrical engine;
engine casing;
impeller (fan);
rubber cushion;
drain plug;
various hoses;
a pump that is powered by a drive belt.

Cooling system: 1 – expansion tank plug; 2 – expansion tank; 3 – radiator supply hose; 4 – hose from the radiator to the expansion tank; 5 – radiator outlet hose; 6 – left radiator tank; 7 – aluminum radiator tubes; 8 – sensor for turning on the electric fan; 9 – right radiator tank; 10 – drain plug; 11 – radiator core; 12 – electric fan casing; 13 – electric fan impeller; 14 – electric motor; 15 – pump gear pulley; 16 – pump impeller; 17 – camshaft drive toothed belt; 18 – heater radiator outlet pipe; 19 – pump supply tube; 20 – hose for supplying fluid to the carburetor starter; 21 – carburetor heating block; 22 – exhaust pipe; 23 – heater supply pipe; 24 – hose for draining fluid from the carburetor heating unit; 25 – thermostat; 26 – hose from expansion tank to thermostat

How the OS works

The electric fan is located on the electric motor shaft. Depending on the indicators of the sensor, it is turned on or off. One of the main elements of the OS is a thermostat valve with a storage tank. which senses changes in air temperature.

If the fluid temperature is around 87 degrees, the main valve turns on and sends fluid through the large circuit. At a temperature of 102 degrees, the valve stops at 8 mm.

Selecting a heater radiator (DAAZ, Luzar, Pramo, Fenox, etc.)

What determines the cost of a radiator?

There are several factors that affect the final cost of a given element.

The first is the manufacturer. Original spare parts are always very expensive, so many car owners try to replace them with imported analogues in the event of a breakdown. Today, the following companies are in great demand in the Russian car market:

DAAZ.
BAKER.

The second is the characteristics of the radiator. For this car model, the radiator is made of two types of metal: copper and aluminum. Each of them has its own unique characteristics that allow it to perform better.

This heat exchanger has no varieties, apart from its design. Therefore, the specific cost will be based only on the characteristics.

Cooling system of an injection engine on a VAZ 2114 (diagram)

Alas, the build quality of the VAZ 2114 radiator and the cooling system as a whole leaves much to be desired, which is why it can fail over time. The main disadvantage of the OS (cooling system) of the “fourteenth” model is the need for constant monitoring, regular maintenance and repair.

The solution to these issues is complicated by the fact that the cooling system of the injection engine on the VAZ 2114 is quite complex and includes 28 elements. The most convenient way to get to know them is on a special chart.

Some useful tips

To drain the coolant, you need to unscrew the plugs on the radiator, on the expansion tank and on the engine cylinder block.
If the cooling system is not functioning well, the culprit may be a liquid cooling pump whose shaft bearings or seals have failed. It needs to be repaired or replaced with a new product.
The cause of failure of the cooling system may be improper operation of the thermostat, which must be repaired or replaced.
It is more convenient to remove the radiator together with the fan. The fan can be removed later if necessary.

You can check the tightness of the removed radiator as follows:

fill the bathtub with water;
lower the product into water and apply pressure of approximately 0.2 MPa;
bubbles will show where leaks have appeared.

Sometimes, to bring the radiator into working condition, it is enough to rinse it with water. It's done like this. The antifreeze or antifreeze is drained and clean distilled water is poured in. The engine starts and runs at 3000 rpm. The temperature should be monitored. They turn off the car and after 7-8 minutes drain the water. If it is not completely clean, the procedure can be repeated. If the fluid has changed color, it needs to be replaced.

The coolant should be changed: antifreeze - after 2 years, antifreeze - after 5 years. The best choice for cooling fluid is antifreeze. The standard cooling system fan is quite noisy. Therefore, it makes sense to replace the original four-blade impeller with a new eight-blade one. When purchasing an impeller, you need to remember that the shaft for its attachment can have a landing thread of 8 mm and 6 mm.

Radiator repair

In some cases, the radiator can be repaired, so you don’t have to buy a new spare part.

Most often, liquid leaks at the junction of plastic and metal parts. If there is a small leak, you can pour a special liquid with a coolant mixture inside the radiator. Thanks to its special composition, this product will seal the defects that caused the leak. If the damage is serious, repairs will no longer save the situation; you will still have to replace the radiator.

To check the tightness of the radiator, you can conduct a simple experiment at home.

Fill the bathroom with enough water to submerge the radiator.
Close all pipe openings tightly.
Lower the radiator under water about 30-50 centimeters. Apply a pressure of 0.2 MPa to it.
Watch what happens. If bubbles appear, the system is not sealed and needs to be repaired or replaced.

Do not even try to repair the radiator after side or frontal impacts in an accident. In such situations, he suffers first of all, and no clogging liquids will help you.

Why the OS does not work

If you don’t know which cooling radiator is best to choose for the VAZ 2114, look at the existing one. Buy an analogue from the manufacturer, or purchase a device with the closest characteristics.

The fourteenth model is equipped with an aluminum radiator with two additional tanks. The radiator design includes:

Radiator;
Upper tank with pipes;
Bottom tank with pipes.

CHOICE

So which heater radiator is better, copper or aluminum for a VAZ 2114? Let's consider the disadvantages of each manufacturing material.

Copper or aluminum?

What can you say about the aluminum stove radiator? Aluminum has good thermal conductivity and therefore heats up quite quickly. True, it also cools down almost immediately. Therefore, when you turn off the engine, the cabin of the 2114 will become cold after a while.

Choosing a heater radiator for a VAZ 2114

Which heater radiator is better for a VAZ 2114? The question is more relevant than ever. All owners of the fourteenth understand that the heating system leaves much to be desired. Not only does the car not warm up enough (although in most cases it is difficult to do anything about the temperature regime in many regions), but the heater also tends to fail, antifreeze begins to leak, and so on.

As a standard, especially on first-generation Samaras, VAZ used copper radiators. Relatively recently, a domestic manufacturer adopted foreign experience and began to use aluminum heaters. And yet, which is the best heater radiator for the VAZ 2114 still needs to be figured out.

Which stove radiator to choose: copper or aluminum

Many people ask the question: which stove radiator is better - copper or aluminum? There can be no definite answer here; each has its own disadvantages and advantages.

Operating principle of the heater

To make the right choice, you need to know the principle of operation of the heating system in a car.

Heat enters the car interior from the engine, this is a side effect of its operation. Heat is generated as a result of fuel combustion and from rubbing surfaces. To remove heat from very hot parts, the engine is equipped with a cooling system, an integral part of which is interior heating. Therefore, the hotter the engine gets, the better the heating. Hot coolant is supplied to the heater core, and the fan, passing air through it, dissipates heat throughout the cabin.

The temperature of the air leaving the deflectors is regulated by a tap located on the line between the motor and the stove. This is a regular shut-off valve with a mechanical or electrical drive; it regulates the amount of coolant that passes through the heater (by increasing the temperature on the control unit, the valve opens more; by decreasing the temperature, it closes). How the stove will work greatly depends on its operation. If it does not work correctly (does not fully open the passage for liquid), then it will be cold in the cabin.

Aluminum or Copper

Obvious advantages of an aluminum radiator:

the presence of side ribs is much larger than that of a competitor
the width of the channels for air flow is greater (this fact can significantly reduce the risk of breakage, and also increases the efficiency of heat supply at idle)

The obvious disadvantage of an aluminum radiator:

heats up very quickly and cools down just as quickly (heat transfer is 209.3 W/m.deg)
As soon as a leak is discovered, it needs to be replaced; such a unit cannot be resuscitated

Obvious advantages of a copper heater:

heats up for a long time and cools down just as long (rather, the second part of the radiator’s property is a plus), heat transfer is 389.6 W/m.deg
can be reanimated: as soon as a leak appears, you just need to solder the hole

Obvious disadvantages of a copper heater:

fewer ribs than the competitor
the channels are small and narrow, they tend to clog quickly, which impairs warming up and adds more reasons for repairs
At idle it barely warms up.
it is difficult to find a high-quality copper heater, since almost everyone who makes units from such material uses impurities and can paint the original material, which naturally reduces the heat transfer property

Today, aluminum radiators are clearly more popular than copper ones. And this is primarily due to the difficulty of finding a high-quality copper unit. And if luck smiles on you, then the price for a copper radiator of a VAZ 2114 stove will be many times higher than for an aluminum radiator. Average. You will get aluminum from 1000 rubles, and copper from 1700 rubles! This is still good, if you install it yourself, the radiator replacement service will cost 800-1000 rubles, on average. By the way, if you can’t solder a leaking copper heater on your own, then taking it to the service center every time will be very expensive; you’ll be able to save up for a limousine. And since all VAZ spare parts tend to be imperfect, keep in mind that you will have to deal with this one way or another. So think about whether it’s worth buying a copper radiator for the VAZ 2114 stove.

Specific examples

The painted copper radiator on the VAZ 2114 . By the way, these are made by an office called “LUZAR”. There is no need to take such units: they are very cold, and have minimal heat transfer! But such devices have a full year warranty.

Why is everything so bad with Luzar? An autopsy will show: the rubber band, which is located next to the passage channels of the ribs, simply becomes damp after a relatively short period of time (less than a year) and the same short mileage. Another big disadvantage of Luzarov radiators is that the pipes are separated from each other, this reduces heat transfer, but makes the cost advantageous.

In general, it is now difficult to find a zero radiator that is relatively recent. Factory junk will crumble, radiators from the manufacturer are not always of decent quality. Therefore, the guideline you can choose is very simple (when choosing a radiator): it just has to be working and not clogged. And what material it is made of is the tenth thing.

Another company, DAAZ, has proven itself very well. There is only one minus - try to find it, and then try to find the original. By the way, the heat output of the Daazov heater is slightly lower than the factory one in the VAZ. And in terms of quality it clearly wins.

Another example is a heater from Oberkraft. The factory carefully approaches the testing process of the unit, which is why it is covered by a good warranty (one year). This device is made of aluminum alloy, which meets modern quality standards. An obvious advantage is the good, uniform distribution of heat throughout the cabin (apparently, they decided not to skimp on pipes), but considering the price, you can’t say that this is an easy purchase – from 1,800 rubles. But there are justifications for this price:

Corrosion resistant
Relatively light in weight
Very important: resistant to temperature changes!
Robust design
Excellent and uniform heat dissipation.

In winter, even the highest quality stove will play tricks in terms of heat output. We offer a couple of good tips on how to make the interior warmer:

You need to change the antifreeze and rinse the entire cooling system - this will remove all the debris in the tubes, making it easier for air to enter the cabin
A great way to improve the microclimate is to install a new stove!
You can also replace the cooling radiator with a new one - this will save the antifreeze from premature fatigue
An option is to replace the pump, because it is responsible for the stability of coolant circulation at idle
Run all the pipes and get rid of air pockets

As strange as it may sound, the stove can be insulated. Yes, for example, after running the entire system, you can glue all the joints, then the heat through the pipes will be precisely directed through the channels towards you, and not spread in an unknown direction. Another way: change the mode of air intake from outside to recirculation (why it is worth explaining this elementary action as one of the ways: yes, because many people think that the stove needs to be plugged! But the air intake does not come clearly from under the hood, which is what they are trying shut up, but just from outside!

So, as soon as such a crazy thought appears in your head, change the air intake mode). The last option for preserving heat is to insulate the interior itself. A very logical action, especially considering the presence of gaps around the body on the fourteenth.

The most common mistakes of those who choose a particular radiator model

Some car owners prefer units. It is not worth buying such devices. The fact is that they have practically no heat transfer! The warranty on units from this manufacturer is 12 months, but the efficiency of such radiators is practically zero.

Sometimes car enthusiasts prefer heaters from. These devices are quite efficient. Manufacturer's warranty - 1 year. These radiators help distribute heat evenly throughout the car's interior, but the cost of these units may seem overpriced.

Advice! Some car enthusiasts are faced with another problem. It turns out that even buying a fairly high-quality radiator may not give the expected result. In order for the stove to work effectively enough, you need to change the antifreeze in advance, and then rinse the cooling system of the machine. In a similar way, you can get rid of various debris in the tubes. This is extremely important, because only after this procedure the air entering the cabin will become cleaner.

We can also recommend replacing the pump. This unit is responsible for how coolant circulates in the car at idle.

Some experienced motorists also recommend getting rid of all air jams.

Which heater radiator to install on a VAZ 2114

Key advantages of aluminum radiators:

A radiator made of aluminum will have significantly more side fins. This makes it more convenient and practical.
The width of all channels in an aluminum radiator is much larger. It is because of this that you can increase the efficiency of supplying warm air at idle.

The main disadvantages of an aluminum radiator:

The aluminum radiator heats up extremely quickly.
It is almost impossible to restore an aluminum radiator that has even a small leak.

Copper radiator of the VAZ 2114 stove and its disadvantages:

A small number of ribs.
The channels are too narrow and small. They clog very quickly, which has the most negative effect on warming up. As a result, such a radiator has to be repaired quite often.
There is practically no heating at idle.
It is too difficult to find a sufficiently efficient copper radiator. Many of them are made from extremely low-quality material with many different impurities. The heat transfer of such devices is at the lowest level.

Expert opinion

We advise you, dear readers, to purchase an aluminum stove radiator. Despite its disadvantages, practice shows that this type of radiator has proven itself well. For example, a VAZ 2114 from 2008, the heater radiator was replaced only in 2014, its service life is about 5 years.
