Radiator for VAZ 2114 - replacement, which one to choose, cost

Cooling radiator for VAZ cars

VAZ 2114 is considered one of the most striking examples of success of the domestic automobile industry. This model is a modified version of the VAZ 2109 and differs from it in the design of the front part of the body, updated headlights and hood, radiator grille design, as well as plastic moldings and spoilers. However, as it became known, the car is susceptible to radiator failures, which can lead to overheating, and as a result, to engine failure.

Choosing a heater radiator for a VAZ 2114

Which heater radiator is better for a VAZ 2114? The question is more pressing than ever. All owners of the fourteenth understand that the heating system leaves much to be desired. It’s not only that the car doesn’t warm up enough (although it’s almost always hard to do anything against the temperature regime in many regions), but the heater also tends to fail, antifreeze starts leaking, etc.. Standard, especially in Samara first generation, VAZ used copper radiators. Relatively not so long ago, a Russian manufacturer adopted foreign experience and began using duralumin heaters. And yet, which is the best heater radiator for the VAZ 2114 still needs to be figured out.

Aluminum or Copper

Trivial advantages of a duralumin radiator:

• the presence of lateral ribs is much larger than that of the opponent
• 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)

A trivial disadvantage of a duralumin radiator:

• heats up very quickly and cools down just as quickly (heat loss is 209.3 W/m.deg)
• As soon as the leak was found, it needed to be replaced; such a unit cannot be resuscitated

Trivial advantages of a copper heater:

• takes a long time to heat up and also takes a long time to cool down (faster, the advantage is the 2nd part of the radiator characteristics), heat loss is 389.6 W/m.deg
• can be revived: as soon as the leak appeared, you just need to solder the hole

Trivial disadvantages of a copper heater:

• fewer ribs than the opponent
• the channels are small and narrow, they tend to clog quickly, which aggravates heating and adds reasons for repairs
• At idle it doesn't actually heat up.
• it is difficult to find a high-quality copper heater, because virtually everyone who makes units from such material uses impurities and can paint the original material, which naturally reduces the heat loss property

Today, duralumin radiators are obviously more popular than copper ones. And this is primarily due to the difficulty of finding a high-quality copper unit. And if fortune smiled on you, then... and copper from 1700 rubles! This is also great if you install it without the help of others; the radiator replacement service will cost 800-1000 rubles, on average. By the way, if you cannot solder a leaking copper heater without the help of others, then taking it to service every time will be very expensive, you can save up for a limousine. And because 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 it, it’s worth taking a copper radiator for the VAZ 2114 .

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.

Main reasons for replacement

There are not many reasons why it may be necessary to replace the radiator of the interior heating system. One of them is the appearance of a leak.

Heat exchangers are made of non-ferrous metals - copper or aluminum.

Gradually, these metals oxidize due to exposure to liquid, which leads to the appearance of cracks through which coolant flows out.

The second reason for replacing the heater radiator is clogging of the tubes with contaminants. The coolant, circulating through the cooling system, washes away corrosion products, small particles, etc.

Moreover, the liquid cannot contain them and these polluting elements settle on surfaces, including the stove radiator.

As a result, the heating system first loses efficiency, and later (if it is heavily contaminated) it simply stops working.

In some cases, radiator blockages can be eliminated by flushing using chemicals.

But if the blockage of the tubes is severe, then the plugs can only be removed from the dirt mechanically. And this can only be done with the radiator removed.

Before you start disassembling, you should first make sure that the problems arose with the radiator.

So, a leak of this element is manifested by the appearance of traces of antifreeze on the floor in the cabin.

But the same result can also be caused by damage to the radiator pipes or loss of tightness at the point of their connection with the heat exchanger.

A decrease in heating efficiency can occur not only due to blockage of the radiator tubes, but also due to severe clogging of its honeycombs.

Dust, fluff, leaves, and insect remains get clogged between the cooling fins, making it difficult to transfer heat to the air.

But in this case, it is very easy to identify the problem - turn on the stove fan at full power and check the air flow from the deflectors.

If it is not strong, the radiator should be cleaned, which also cannot be done efficiently without removing the element.

The stove may also stop heating due to the radiator becoming airy, which often happens when replacing the coolant. Often the cause is a malfunction of the cooling system elements, especially the thermostat.

In general, before removing the heater radiator, you should make sure that it is the cause of poor interior heating that is hidden there. And for this you will have to check almost the entire cooling system.

So which heater radiator is better for a VAZ 2114

Before replacing the radiator, you need to compare all the advantages and disadvantages of heaters made from different materials. Only after this can a final decision be made. It is worth taking into account the opinions of experts in this field. Many of them believe that aluminum parts are much more practical.

You should not buy painted radiators. This is a fairly common mistake made by many young car enthusiasts. The problem with painted radiators is that they have fairly low heat transfer.

In addition, they cause unpleasant odors in the car interior. Let's hope that the answer to the question of which radiator is better aluminum or copper for the VAZ 2114, has now been found.

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.

Which heater radiator for the VAZ 2114 is better - copper or aluminum

Increasingly, motorists are wondering which heater radiator is better, copper or aluminum, for a VAZ 2114. This question is especially relevant in winter, especially if the car enthusiast lives in one of the northern regions of the country.

In addition, the issue is extremely important due to the fact that the standard car heating system is quite mediocre. The car warms up extremely slowly. As a result, the driver and passengers can freeze very quickly.

Important! Quite often the heater breaks down completely and the motorist needs to have it repaired. Sometimes there are smaller problems with the radiator (it may start leaking, etc.).

Replacing the radiator (cooling) VAZ Samara 2114,08,09,99,2115

Previously, the VAZ company used only copper radiators, but recently the company decided to try using aluminum radiators. So which of these radiators is preferable to use on a VAZ? 2114?

Today, aluminum radiators are much more popular than copper radiators. The reason for its popularity is that finding a high-quality copper radiator has recently become too difficult.

Another problem is that many models of copper radiators cost exorbitant amounts of money. Not every VAZ 2114 owner can afford to purchase such a unit. aluminum radiator

If we add to this the cost of replacing radiators at a service center, then in the end the car enthusiast’s wallet will become noticeably lighter. Not everyone will be able to replace this unit on their own, so it is worthwhile to include in the budget for replacing the radiator in advance the cost of specialist work.

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

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.

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

Alas, the build quality of the VAZ 2114 radiator and the cooling 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.

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.)

COOLING SYSTEM PROBLEMS

As a rule, due to malfunctions in the cooling system, the engine overheats, and this leads to engine failure. Any of the elements may be faulty.

Radiator:

1. It may leak. Possible leakage through aluminum tubes and plastic tanks. Often the plastic outlet for the return hose of the expansion tank breaks off.
2. It may clog, and for this reason the engine will heat up.

Pipes. Because of them, antifreeze leaks due to the fact that the pipe:

1. Ragged.
2. Old and lost elasticity.

Thermostat. Depending on how incorrectly the valve in the thermostat operates, the internal combustion engine can:

1. Overheat (in this case, the antifreeze “throws out” through the expansion tank).
2. Do not reach operating temperature. As a result, the car drives poorly, and in cold weather it is cold inside the car.

Water pump (three main problems):

1. Noise and play in bearings. It is not worth driving with such a defect for a long time; the pump may jam or fall apart.
2. Liquid is leaking through the inspection hole. It also signals the imminent “death” of the part.
3. Broken impeller. With such a defect, the engine overheats very quickly.

Cooling Fan:

• A faulty fan also leads to overheating of the internal combustion engine.

The clamps may be faulty or poorly tightened. It happens that thin hoses become clogged with debris (“return”, throttle valve heating).

Radiator replacement

The replacement procedure itself is as follows.

• Unscrew the plug from the expansion tank and the cylinder and radiator plugs.
• Drain the coolant into a large container.
• Disconnect the radiator ventilation system from the battery.
• Remove the silicone pipes of the VAZ 2114 cooling system by disconnecting them from the radiator and tank.
• Remove the mounting bolts from the casing.
• Hold the radiator and remove the skin and fan together.
• This will completely free the radiator, so you can easily replace it with a new one.
• Assembly of the unit is carried out in reverse order. After replacing the radiator, start the engine and check the efficiency of the new unit.

Replacing the coolant

To normalize the cooling system on a VAZ 2114, sometimes it is enough to replace the coolant. To determine when this needs to be done, you should know some nuances:

• The effective life of antifreeze is 2 years, and antifreeze is 5 years;
• Typically, replacing antifreeze is required after a mileage of 20-40 thousand kilometers, depending on operating conditions;
• A changed color of the composition indicates that it needs to be replaced.

Experts recommend using antifreeze as a liquid. since it has a long service life and does not wear out the system so intensively. The only thing that speaks in favor of antifreeze is its affordable price.

Before adding new fluid, the system should be flushed. For this:

• Drain all existing coolant from the system;
• Screw the plugs tightly;
• Fill with high-quality distilled water to the maximum;
• Start the engine and bring it to operating temperature;
• The revolutions should be about 3 thousand. Avoid overheating the engine;
• After turning off the engine, leave the car for 7 minutes, after which the water is drained. If the system is heavily contaminated, the procedure must be repeated until completely clean distillate begins to pour out.

Installing a new radiator and how much does it cost?

In order to replace a cooling radiator, you do not need to have high knowledge in the field of mechanical engineering. It is enough to have some tools and follow the following algorithm without trying to change the order of actions in it.

First you need to drain all the liquid from it. There is a plug in the lower left corner of the heat exchanger specifically for this purpose. Then you need to unscrew the air filter, which is secured with two 13 bolts. Loosen the clamp and release the filter from the air duct. Then you need to separate the radiator from the “TV”. To do this, you need to unscrew the top mount of the radiator by unscrewing a couple of 8-mm nuts and remove the clamp.

Next, remove the pipes. This can be done by unscrewing just the bolts on the clamp, using a 7 or 8 key. The same must be done with the upper pipe. It is worth remembering that the pipes are sealed with sealant if they have never been changed since factory assembly, so do not be alarmed if it does not come off. It is necessary to rip them off with careful movements.

Having disconnected the fan power plug, you can safely remove the radiator from under the hood. Here you need to be careful not to lose the pads located in pairs on the lower corners of the radiator.

Now it's the fan's turn. It must be detached from the radiator, to which it is attached using four 10mm bolts. Having installed the fan on the new radiator, you need to do everything in the reverse order.

You can also order this service from car service employees. It costs about 1000-1500 rubles. Depending on the region. If we are talking about large cities, then the cost will be about 3,000 rubles.

You can buy a heat exchanger for the VAZ 2114 at any auto parts store or online store.

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.

Replace without removing the panel

But no matter what method is used, you will first have to drain the coolant from the system. Therefore, you will have to stock up on antifreeze in the required quantity in advance.

First, let's look at the replacement method without removing the panel. As already mentioned, this will require making cuts in some places.

To complete the work you will need:

• Set of screwdrivers of different lengths;
• Hacksaw blade for metal;
• Flat container for draining residual coolant from the radiator;
• Rags.

Having prepared everything and drained the coolant from the cooling system, you can begin work:

1. We remove the storage box (glove compartment) from the panel, for which it is necessary to unscrew 6 screws securing it;
2. Remove the side trims on the center console;

3. Use a metal blade to make the necessary cuts: The first cut is vertical
   , we do it on the inner wall of the panel near the center console (behind the metal strip of the glove compartment). Moreover, here you will have to make two cuts.
   The second cut is horizontal
   , runs in the upper part along the rear wall of the opening under the glove compartment.

   The third is also vertical
   , but not end-to-end. It is done on the right on the rear wall of the lower storage shelf of the panel;

4. After all the cuts, part of the panel together with the wall can be bent down, which will provide access to the radiator. We bend this part and fix it;

5. Unscrew the near bracket for fastening the heating system flap control cable and move the cable to the side;

6. Loosen the clamps of the coolant supply pipes to the radiator. In this case, you should place a prepared container under the connection points, since liquid will flow out of the heat exchanger. Remove the pipes;

7. We unscrew the three screws securing the radiator, remove it and immediately inspect it.

Afterwards we replace the heat exchanger, fix it in the seat, connect the pipes to it and clamp it with clamps. To make the pipes fit easily, lubricate them with soap.

At this stage of work, you should fill the cooling system with liquid and run it to remove air pockets.

Next, it remains to make sure that the connections between the pipes and the radiator are not leaking, and that the damper and faucet are connected without errors.

After this, all that remains is to return the cut part of the panel to its place and fix it. To do this, you can use screws and plates.

The main thing is to fix it in several places so that in the future the cut off part does not rattle when moving. Use sealant or silicone.

This method is convenient because if you replace the radiator again (which is quite possible), all the work will be very simple - you just need to remove the storage box and unscrew a few screws.

In addition, all cuts are made in such places that after assembling the panel and installing the glove compartment they will not be noticeable.
